INSTRUCTIONS TO BIDDERS

FORM OF BID. Bids shall be made on the Bid forms found herein. Bidders shall include all forms and fill in all blank spaces, including inserting “N/A” (for not applicable) where necessary. The Bid shall be enclosed in a sealed envelope bearing the Bidder’s name and the Project name and identification number as described in the Notice Inviting Bids.

Any Bid not accompanied by a Contractor’s Statement completed with all information required and bearing the signature of the Bidder’s duly authorized representative under penalty of perjury may be deemed non-responsive and rejected. If the City determines that any information provided by a Bidder in the Contractor’s Statement is false or misleading, or is so incomplete as to be false or misleading, the City may reject the Bid submitted by such Bidder as being non- responsive.

DELIVERY OF BIDS. The Bid shall be delivered by the time and date and to the place specified in the Notice Inviting Bids. No oral, faxed, emailed, or telephonic Bids or alternatives will be considered. Bidders are solely responsible for ensuring that their Bids are received in proper time, and Bidders assume all risks arising out of their chosen means of delivery. Any Bid received after the Bid submission deadline shall be returned unopened. Bidders are invited to be present for Bid opening. Accepted Bids shall become the property of the City.

AMENDED BIDS. Unauthorized conditions, limitations or provisos attached to a Bid may cause the Bid to be deemed incomplete and non-responsive.

WITHDRAWAL OF BID. A Bid may be withdrawn without prejudice upon written request by the Bidder filed with the City Clerk before the Bid submission deadline. Bids must remain valid and shall not be subject to withdrawal for 90 Days after the Bid opening date.

BIDDER’S SECURITY. Each Bid shall be accompanied by cash, a certified or cashier’s check payable to the City, or a satisfactory Bid Bond in favor of the City executed by the Bidder as principal and an admitted surety insurer as Surety, in an amount not less than ten percent of the amount set forth in the Bid. The cash, check or Bid Bond shall be given as a guarantee that, if selected, the Bidder will execute the Contract in conformity with the Contract Documents, and will provide the evidence of insurance and furnish the specified Bonds, within ten calendar days after the date of delivery of the Contract Documents to the Bidder. In case of the Bidder’s refusal or failure to do so, the City may award the Contract to the next lowest responsible bidder, and the cash, check, or Bond (as applicable) of the lowest Bidder shall be forfeited to the City to the extent permitted by law. No Bid Bond will be accepted unless it conforms substantially to the form provided in these Contract Documents.

QUANTITIES APPROXIMATE. Any quantities shown in the Bid form or elsewhere herein shall be considered as approximations listed to serve as a general indication of the amount of Work or materials to be performed or furnished, and as basis for the Bid comparison. The City does not guarantee that the actual amounts required will correspond with those shown. As deemed necessary or convenient, the City may increase or decrease the amount of any item or portion of Work or material to be performed or furnished or omit any such item or portion, in accordance with the Contract Documents.

ADDENDA. The City Engineer may, from time to time, issue Addenda to the Contract Documents. The City shall post all documents to the City’s website at https://www.citymb.info. The Addenda may also be posted to BidSync at https://www.bidsync.com. Bidders are

12100-0001\2410807v2.doc City I-1 of MB Form

responsible for ensuring that they have received any and all Addenda. It is the Bidder’s responsibility to actively check BidSync and/or the City’s website for Addenda or bulletin updates. Each Bidder is responsible for verifying that it has received all Addenda issued. Bidders must acknowledge receipt of all Addenda, if any. Failure to acknowledge receipt of all Addenda may cause a Bid to be deemed incomplete and non-responsive.

DISCREPANCIES IN BIDS. Each Bidder shall set forth as to each item of Work, in clearly legible words and figures, a unit or line item Bid amount for the item in the respective spaces provided for this purpose.

In case of discrepancy between the unit price and the extended amount set forth for the item, the unit price shall prevail. However, if the amount set forth as a unit price is ambiguous, unintelligible or uncertain for any cause, or is omitted, or if the unit price is the same amount as the entry in the “extended amount” column, then the amount set forth in the “extended amount” column for the item shall prevail in accordance with the following:

(1) As to lump sum items, the amount set forth in the “extended amount” column shall be the unit price.

(2) As to unit price items, the amount set forth in the “extended amount” column shall be divided by the estimated quantity for the item set forth in the Bid documents, and the price thus obtained shall be the unit price.

In case of discrepancy between words and figures, the words shall prevail.

COMPETENCY OF BIDDERS. In evaluating Bidder responsibility, consideration will be given not only to the financial standing, but also to the general competency of the Bidder for the performance of the Project. Each Bidder shall set forth in the designated area of the Bid form a statement of its experience. No Contract will be executed with a Bidder that is not licensed and registered with the DIR in accordance with State law, and with any applicable specific licensing requirements specified in these Contract Documents. These licensing and registration requirements for Contractors shall also apply to all Subcontractors.

BIDDER’S EXAMINATION OF SITE AND CONTRACT DOCUMENTS. The Bidder, at its sole cost and expense, is required to carefully examine the Contract Documents and the Project site to become fully acquainted with the conditions affecting the Work. The failure of a Bidder to receive or examine any of the Contract Documents or to inspect the site shall not relieve such Bidder from any obligation relating to the Bid, the Contract, or the Work required under the Contract Documents. The City assumes no responsibility or liability to any Bidder for, nor shall the City be bound by, any understandings, oral representations or oral agreements of the City’s agents, employees or officers concerning the Contract Documents or the Work made prior to execution of the Contract. By submitting a Bid, Bidder represents: (1) that Bidder has read and understands the Contract Documents; (2) the Bid is made in compliance with the Contract Documents and is based upon the labor, materials, equipment, and systems required by the Contract Documents; (3) that Bidder understands that all labor, materials, equipment, and systems to be furnished for the Work shall be furnished for the prices bid; (4) that it has visited the Project site, familiarized itself with the local conditions under which the Work is to be performed; (5) that it is fully experienced, qualified and competent to perform the Work set forth in the Contract Documents; (6) that it shall not damage or endanger and shall preserve and protect adjacent properties; (7) that it is properly equipped, organized, and financed to perform the Work; (8) that it is properly permitted and licensed by the California Contractors State Licensing Board

12100-0001\2410807v2.doc City I-2 of MB Form

to perform the Work; (9) that it has familiarized itself with all conditions bearing upon transportation, disposal, handling, and storage of materials; (10) that it has familiarized itself with the availability of labor, water, electric power, and roads; (11) that it has familiarized itself with uncertainties of weather, or similar physical conditions at the Project site; (12) that it has familiarized itself with the character of equipment and facilities needed preliminary to and during performance of the Work; (13) that it has familiarized itself with the staging and material storage constraints of the Project site and surrounding buildings and will confine its staging and storage operations to approved areas; and (14) that it will coordinate its construction activities with the other contractors performing work on the Project site, if any, including, but not limited to, any separate contractor retained by the City.

No information derived from an inspection of records or investigation will in any way relieve the Contractor from its obligations under the Contract Documents nor entitle the Contractor to any additional compensation. The Contractor shall not make any claim against the City based upon ignorance or misunderstanding of any condition of the Project site or of the requirements set forth in the Contract Documents. No claim for additional compensation will be allowed which is based on a lack of knowledge of the above items. Bidders assume all risks in connection with performance of the Work in accordance with the Contract Documents, regardless of actual conditions encountered, and waive and release the City with respect to any and all claims and liabilities in connection therewith, to the extent permitted by law.

The omission of any portion or item of Work from the Bid that is reasonably inferable from the Contract Documents is not a basis for adjustment of the Contract Price or the Contract Time.

DISQUALIFICATION OF BIDDERS. No Person shall be allowed to make, file or be interested in more than one Bid for the Project. A Person that has submitted a sub-bid to a Bidder, or that has quoted prices of materials to a Bidder, is not thereby disqualified from submitting a sub-proposal or quoting prices to other Bidders or from making a prime Bid. If there is a reason to believe that collusion exists among the Bidders, all affected Bids will be rejected.

RETURN OF BID SECURITY. The successful Bidder’s Bid security shall be held until the Contract is executed. Bid security shall be returned to the unsuccessful Bidders within a reasonable time, which in any case shall not exceed 90 Days after the successful Bidder has signed the Contract.

AWARD OF CONTRACT. The City reserves the right to reject any or all Bids or any parts thereof or to waive any irregularities or informalities in any Bid or in the bidding. The Contract award, if made, will be to the lowest responsible, responsive Bidder and is anticipated to occur within 90 calendar Days after the Bid opening. The Contract award may be made after that period if the selected Bidder has not given the City written notice of the withdrawal of its Bid.

DETERMINATION OF LOWEST BIDDER IF ADDITIVE OR DEDUCTIVE ITEMS. In accordance with Public Contract Code Section 20103.8, the lowest Bid shall be determined by comparing the total Bid price of all Base Bid Items and Additive Alternate Bid Items, using the Engineer’s estimate of quantities for the Work as set forth in the Bidder’s Proposal. The amount of the contract award will be based on the available budget for the project. It may be only for the Base Bid or if the budget allows, include Additive Bid Items. In the event that any or all of the Alternate Bid Items are not awarded as part of the Contract, the City reserves the right to add any or all of the Alternate Bid Items by Change Order or Construction Change Directive at the prices set forth in the Bid.

12100-0001\2410807v2.doc City I-3 of MB Form

TRENCHING. If the Project involves the construction of a pipeline, sewer, sewage disposal system, boring and jacking pits, or similar trenches or open excavations, which are five feet deep or more, then each Bidder must submit, as a Bid item, adequate sheeting, shoring, and bracing, or an equivalent method, for the protection of life or limb, which shall conform to applicable safety orders. This final submission must be accepted by the City in advance of excavation and must include a detailed plan showing the design of shoring, bracing, sloping, or other provisions to be made for worker protection from caving ground during the excavation Work. If such plan varies from the shoring system standards, the plan shall be prepared by a registered civil or structural engineer.

LISTING SUBCONTRACTORS. Each Bidder shall submit a list of the proposed Subcontractors on the Project, as required by the Subletting and Subcontracting Fair Practices Act (Public Contract Code Section 4100, et seq.).

WORK OF SUBCONTRACTORS. All Bidders are encouraged to disseminate all of the Specifications, Drawings, and other Contract Documents to all persons or entities submitting sub- bids to the Bidder.

INELIGIBLE SUBCONTRACTORS. The successful Bidder is prohibited from performing Work on the Project with any Subcontractor who is ineligible to perform work on a public works project pursuant to Sections 1777.1 or 1777.7 of the California Labor Code. By submitting a Bid, each Bidder certifies that it has investigated the eligibility of each and every listed Subcontractor and has determined that none is ineligible to perform Work pursuant to the Labor Code.

EXECUTION OF CONTRACT. The selected Bidder shall execute the Contract in the form included in these Contract Documents within ten calendar days from the date of delivery of the Contract Documents to the Bidder. Additionally, the selected Bidder shall also secure all insurance and Bonds as herein specified, and provide copies to the City, within ten calendar days from the date of delivery of the Contract Documents to the Bidder. Failure or refusal to execute the Contract or to conform to any of the stipulated requirements shall be just cause for the annulment of the award and forfeiture of the Bidder’s security. In such event, the City may declare the Bidder’s security forfeited to the extent permitted by law, and the City may award the Contract to the next lowest responsible Bidder or may reject all bids.

SIGNATURES. The Bidder shall execute all documents requiring signatures, and shall cause to be notarized all documents that indicate such a requirement. The Bidder shall provide evidence satisfactory to the City, such as an authenticated resolution of its board of directors or a power of attorney, indicating the capacity of the person(s) signing the Bid to bind the Bidder to the Bid and any Contract arising therefrom.

INSURANCE AND BONDS. The Contractor shall not begin Work until it has given the City evidence of all required insurance coverage (including all additional insured endorsements), a Bond guaranteeing the Contractor’s faithful performance of the Contract, and a Bond securing the payment of claims for labor and materials. Where a Contractor has entered into an agreement with a Professional Employment Organization (PEO) to provide human resources, workers' compensation insurance, or other benefits to the Contractor's employees, the Contractor must also submit the agreement with the PEO for review by the City.

TELEPHONES. Bidders are hereby notified that the City will not provide telephones for their use at the time of Bid submission.

12100-0001\2410807v2.doc City I-4 of MB Form

INTERPRETATION OF CONTRACT DOCUMENTS. Any Bidder that is in doubt as to the intended meaning of any part of the Contract Documents, or that finds discrepancies in or omissions from the Contract Documents, may submit to the City Engineer a written request for an interpretation or correction not later than the date specified in the Notice Inviting Bids. Requests for clarification received after this date will be disregarded. Please indicate the Project and identification number in the request for clarification. Telephonic requests will not be taken. Any interpretation or correction of the Contract Documents will be made only by a written Addendum. No oral interpretation of any provision in the Contract Documents shall be binding.

TRADE NAMES OR EQUALS. Requests to substitute an equivalent item for a brand or trade name item must be made by written request submitted no later than ten calendar days after the award of contract. Requests received after this time shall not be considered. Requests shall clearly describe the product for which approval is requested, including all data necessary to demonstrate acceptability.

TAXES. Except as may be otherwise specifically provided herein, all sales and/or use taxes assessed by federal, State or local authorities on materials used or furnished by the Contractor in performing the Work shall be paid by the Contractor. The Bidder shall calculate payment for all sales, unemployment, pension and other taxes imposed by federal, State, and local law and shall include these payments in computing the Bid.

2-7 SUBSURFACE DATA

If the City or its consultants have made investigations of subsurface conditions in areas where the Work is to be performed, such investigations shall be deemed made only for the purpose of study and design. If a geotechnical or other report has been prepared for the Project, the Contractor may inspect the records pertaining to such investigations subject to and upon the conditions hereinafter set forth. The inspection of the records shall be communicated with the City Staff. It is the Contractor’s sole responsibility to determine whether such investigations exist, and the City makes no affirmative or negative representation concerning the existence of such investigations.

The records of any such investigations are made available solely for the convenience of the Contractor. It is expressly understood and agreed that the City, the Engineer, their agents, consultants or employees assume no responsibility whatsoever with respect to the sufficiency or accuracy of any investigations, the records thereof, and the interpretations set forth therein.

If the Engineer deems it expedient and not in the best interest of the City to correct work injured or done not in accordance with the Contract, the defective work may be accepted subject to an equitable deduction from the Contract Price which may be made therefor by the City upon certification from the Engineer.

Reexamination of any work may be ordered by the Engineer at any time prior to Final Acceptance and, if so ordered, the work must be uncovered by the Contractor.

Add the following paragraph to the end of Subsection 3-1.1:

If the Contractor alleges that instructions issued after the date of the Contract will result in increases to the Contract Price or Contract Time, if latent or unforeseen conditions require modification of the Contract Documents, or the Contractor otherwise becomes aware of the need for or desirability of a change in the Work, a Change Order Proposal (“COP”) may be submitted to the City in writing, using the forms provided herein in Subsection 3-6.2 of the General Provisions, and must specify the reasons for such change, including relevant circumstances and impacts on the construction schedule. The Contractor may request additional compensation and/or time through a COP but not for instances that occurred more than ten calendar days prior to the COP. The Contractor’s failure to initiate a COP within such period shall be deemed a waiver of the right to adjustment of the Contract Price or the Contract Time for the alleged change, unless such waiver is prohibited under state law. Any COP that is approved by the City will be incorporated in a Change Order or Construction Change Directive. If the City determines that the Work in question is not a change, the City shall issue a Work Directive, ordering the Contractor to proceed with the Work without delay. If the COP is denied but the Contractor believes that it does have merit, the Contractor may submit a claim to the City.

3-2 CHANGES INITIATED BY THE AGENCY

The City reserves the right, without notice to the Surety, to increase or decrease the quantity of any item or portion of the Work described in the Contract Documents or to alter or omit portions of the Work so described, as may be deemed necessary or expedient by the Engineer, without in any way making the Contract void. Such increases, alterations or decreases of Work shall be considered and treated as though originally contracted for, and shall be subject to all the terms, conditions and provisions of the original Contract. The Contractor shall not claim or bring suit for damages, whether for loss of profits or otherwise, on account of any decrease, alteration or omission of any kind of Work to be done.

B. Construction Change Directive approved by the City Council, City Manager, Public Works Director, or City Engineer (dollar value of approval authority for each as per City policy);

A change that causes the total value of all changes to exceed the Contract contingency amount established at the time of award of the Contract must be approved by the City Council. No payments in excess of the original Contract Price will be made until a Change Order is approved in the normal course of business. The City may, at any time, without notice to the Contractor’s surety(ies), order changes in the Work within the general scope of the Contract. Such changes in the Work shall not relieve or release the surety(ies) of its(their) obligations under the Performance and Payment Bonds issued for the Project. Changes in the Work made pursuant to this Article 3 shall in no way release any guarantee or warranty provided by the Contractor.

12100-0001\2410807v2.doc City GP-9 of MB Form

The City may issue a Change Order Proposal Request (“COPR”), in writing, to the Contractor, describing a proposed change to the Work and requesting that the Contractor submit an itemized Change Order Proposal (“COP”) to the City, using the forms provided herein in Subsection 3-6.2 of the General Provisions, within ten calendar days after the City’s issuance of the COPR. If the Contractor fails to submit a COP within such period of time, it shall be presumed that the change described in the City’s COPR will not result in an increase to the Contract Price or Contract Time and the change shall be performed by the Contractor without such increases. A COPR does not authorize the Contractor to commence performance of the changed work. The Contractor shall not perform any change until receipt of the City’s written approval. If the City approves the Contractor’s COP, City shall issue a Change Order.

Whenever a change is pending, the Contractor shall notify the City if it is necessary to halt other Work in the area of the change that would be affected thereby, until such time as the change is authorized.

Any change to the Contract Price shall be in a sum mutually agreed to by the Contractor and the City.

By execution of any Change Order, the Contractor agrees that the Change Order constitutes a complete accord and satisfaction with respect to all claims for schedule extension, Impacts, or any costs of whatsoever nature, character or kind arising out of or incidental to the Change Order. No action, conduct, omission, product failure, or course of dealing by the City shall act to waive, modify, change, or alter the requirement that Change Orders must be in writing, signed by the City and the Contractor, and that such written Change Orders are the exclusive method for effectuating any change to the Contract Sum and/or Contract Time.

The cost of labor will be the actual cost for wages prevailing locally for each craft or type of worker (including foreman when authorized by the Engineer) performing the Extra Work at the time the Extra Work is done, plus liability insurance, health and welfare, pension, vacation, apprenticeship funds, and other direct costs, as well as assessments or benefits required by lawful collective bargaining agreements.

To the actual wages, as defined above, will be added a labor surcharge set forth in the California Department of Transportation publication entitled “Labor Surcharge and Equipment Rental Rates” that is in effect on the date upon which the Extra Work is performed. The labor surcharge shall constitute full compensation for all payments imposed by State and federal laws and for all other payments made to, or on behalf of, the workers, other than actual wages, subsistence and travel paid to the workers. The labor surcharge includes Workers’ Compensation, Social Security, Medicare, Federal Unemployment, State Unemployment, and State Training taxes.

Except when direct supervision is provided by working foremen whose time is included in accordance with Subsection 3-2.2.2, the cost of direct supervision of Extra Work, when such direct supervision is provided exclusively for the Extra Work and not in conjunction with or at the same time as supervision for other Work, and when approved in advance in writing by the Engineer, may be charged to the Extra Work. Such cost includes only the actual cost of supervision labor,

12100-0001\2410807v2.doc City GP-12 of MB Form

plus payroll taxes, insurance, and pension costs. The cost of transportation, use of vehicle, and other costs incurred by supervision will not be allowed.

3-3.2.2.2 Materials

Add the following to Subsection 3-3.2.2.2:

If the Contractor does not furnish satisfactory evidence of the cost of the materials from the actual supplier thereof within five (5) days following delivery of materials to the Work site, the Engineer reserves the right to establish the cost of the materials at the lowest current wholesale prices at which the materials were available, in the quantities concerned, delivered to the location of the Work site, less any discounts.

3-3.2.2.3 Tool and Equipment Rental

Delete Subsection 3-3.2.2.3 in its entirety and substitute the following:

No payment will be made for individual pieces of equipment or tools not listed in the California Department of Transportation publication entitled “Labor Surcharge and Equipment Rental Rates” that is in effect on the date upon which the Extra Work is performed and that have a replacement value of $200.00 or less, whether or not consumed by use. Such equipment or tools shall be considered to be small tools.

The Contractor will be paid for the use of equipment at the rental rates listed for such equipment in the Labor Surcharge and Equipment Rental Rates publication that is in effect on the date upon which the Extra Work is performed.

Move in and out, or minimum charges other than the hourly rate, shall not apply to equipment available from the force already on the Project site.

For equipment that is rented from a local equipment agency, the Contractor will be paid at the hourly rate shown on the rental agency invoice or agreement for the time the equipment is used on Extra Work. If a minimum equipment rental amount is required by the local equipment rental agency, the actual amount charged will be paid to the Contractor.

If it is deemed necessary by the Engineer to use equipment not listed in the Labor Surcharge and Equipment Rental Rates publication, a suitable rental rate for that equipment will be established by the Engineer. The Contractor may furnish any cost data that might assist the Engineer in the establishment of the rental rate. If the rental rate established by the Engineer is $10.00 per hour or less, the provisions above concerning rental of equipment from a local equipment agency shall apply.

Rental time will not be allowed while equipment is inoperative due to breakdowns.

When owner operated equipment is used to perform Extra Work to be paid on a force account basis, the Contractor will be paid for the equipment and operator as follows:

1) Labor ...... 20

2) Materials ...... 15

3) Equipment Rental ...... 15

4) Other Items and Expenditures...... 15

To the sum of the costs and markups provided for in this subsection, one percent shall be added as compensation for bonding.

3-3.2.3.2 Work by Subcontractor.

For Extra Work performed by a Subcontractor, the markup established in Subsection 3-3.2.3.1 of the General Provisions shall be applied to the Subcontractor’s costs. An additional five percent shall be added to the Subcontractor’s final cost, which shall reimburse the Contractor for administrative costs, including overhead and profit.

3-3.2.3.3 Work by Sub-Subcontractor.

3-3.2.3.4 Work by Specialist.

If the Engineer and the Contractor agree that a service or an item of Extra Work cannot be performed by the forces of the Contractor or those of any of its Subcontractors or sub- Subcontractors, such service or Extra Work item may be performed by a specialist. Invoices for such services or items of Extra Work calculated on the basis of current market prices may be accepted without complete itemization of labor, material, and equipment rental costs when it is impracticable and not in accordance with the established practice of the special service industry to provide such complete itemization.

12100-0001\2410807v2.doc City GP-14 of MB Form

If the Contractor is required to perform Extra Work that requires a fabrication or matching process in a fabrication or machine shop facilities away from the Project site, the charges for that portion of the Extra Work performed in such facility may, by agreement between the Contractor and Engineer, be accepted as a specialist billing.

For Extra Work performed by a specialist, 15% shall be added to the specialist’s invoice price less a credit to the City for any cash or trade discount offered or available, whether or not such discount may have been taken; such percentage shall reimburse the Contractor for administrative costs, including overhead and profit.

3-3.2.3.5 Work not Covered by Unit Prices.

Markup for overhead and profit on any change in the Work for an Item of Work not covered by a Contract Unit Price that involves both added and deleted Work shall be paid, in accordance with this Subsection 3-3.2.3 of the General Provisions, only if the net cost increases the Contract Price (i.e., if the cost for added Work exceeds the cost for deleted Work).

3-3.3 Daily Reports by Contractor

Such invoices shall be submitted with the daily reports, or if not available, they shall be submitted with subsequent daily reports. The Contractor shall maintain the Contractor’s records in such a manner as to provide a clear accounting of the costs.

Upon completion of the Extra Work, the Contractor shall submit a summary of costs, including markup for overhead and profit. All costs shall be in accordance with Subsection 3-3.2, “Payment,” of the Standard Specifications and the General Provisions. The signature of the City’s Inspector on a daily report shall indicate agreement with the information reflected therein, not that the Contractor is entitled to payment of the costs in the report. The Engineer shall review the daily reports. The Engineer shall compare the Inspector’s records with the completed daily reports furnished by the Contractor and make any necessary adjustments. When the daily reports are agreed upon and signed by both parties, these reports shall become the basis of payment for the Extra Work performed.

3-3.4 Extension of Time

Add the following as Subsection 3-3.4:

If the Contractor is delayed in completing the Extra Work due to a change ordered by the City, the time for completion of Work will be extended in accordance with Subsection 6-6.1 of these General Provisions.

6-5 TERMINATION OF THE CONTRACT FOR CONVENIENCE

In addition to the reasons for termination listed in Section 6-5 of the Standard Specifications, which allow termination upon any written notice, the City may cancel the Contract for any other reason or for no reason upon 30 Days’ written notice. The rest of the procedure outlined in Section 6-5 shall apply to such situation, including the Contractor’s required immediate notification of Subcontractors and suppliers and the payment.

or for no reason) shall the total amount of money to Contractor exceed the amount which would have been paid to the Contractor for the full performance of the services described in the Contract.

Furthermore, some of the City’s projects are funded in whole or in part by funds other than the City’s General Fund. If this Project is funded by such external funds in whole or in part, or if those external funds are terminated or reduced at any time and for any reason or for no reason at all, and the City determines at its discretion that no other funding is available for continuation of this Project, the City will not be obligated to continue funding for the services contained in these Contract Documents and may terminate the Project immediately.

Unless otherwise agreed in writing, an adjustment to the Contract time by reason of a Change Order shall be agreed to at the time the Change Order is issued and accepted by the Contractor.

6-6.1 Extensions of Time

In executing such Bonds, the Sureties shall be deemed to have expressly agreed to any such extensions of time. The amount of time allowed by an extension of time shall be limited to the period of the delay giving rise to the same as determined by the City. Notwithstanding any dispute which may arise in connection with a claim for adjustment of the Contract time, the Contractor shall promptly proceed with the Work.

6-6.2 Payment for Delays

Notwithstanding any other terms and conditions of the Contract Documents, the City shall have no obligation whatsoever to increase the Contract Price or extend the time for delays.

Any accepted delay claim shall be fully compensated for by an extension of time to complete the performance of the Work.

This Section shall not apply to compensable delays caused solely by the City. If a compensable delay is caused solely by the City, the Contractor shall be entitled to a Change Order that: (1) extends the time for completion of the Contract by the amount of delay caused by the City; and (2) provides equitable adjustment, as determined by the City, to the Contractor.

In accordance with Public Contract Code Section 7107, if no claims have been filed and are still pending, the amount deducted from the final estimate and retained by the City will be paid to the Contractor except such amounts as are required by law to be withheld by properly executed and filed notices to stop payment, or as may be withheld for any other lawful purposes.

Whenever the Contractor is required to perform work or furnish equipment, labor, tools, and materials of any class for which no price is fixed in the proposal, it shall be understood that such work, equipment, labor, tools, and materials shall be provided without extra charge, allowance, or direct payment of any kind. The cost of performing such work or furnishing such equipment, labor, tools, and materials shall be included in the unit bid prices in the proposal most closely related to the work and no additional compensation will be made thereof.

If any portion of the work done or materials furnished under the Contract shall prove defective or not in accordance with the Specifications and Contract drawings, and if the imperfection in the same is not of sufficient magnitude or importance to make the work dangerous or undesirable, the Engineer shall have the right and authority to retain the work instead of requiring it to be removed and reconstructed, but he shall make such deductions therefor in the payment due the Contractor as may be just and reasonable.

Delete the tenth paragraph of Subsection 9-3.1 and substitute the following:

Not later than 60 days from the date of Final Acceptance, the five percent deducted and retained from each progress estimate (see Subsection 9-3.2 of the Standard Specifications and these General Provisions) by the City will be paid to the Contractor except such amounts as are required by law to be withheld by properly executed and filed notices to stop payment, or as may be authorized by the Contract to be further retained.

9-3.2.5 Substitute Security

In accordance with Public Contract Code Section 22300, the Contractor may request that it be permitted to substitute securities in lieu of having retention withheld by the City from progress payments when such payments become due or, in the alternative, the Contractor may request that the City make payments of earned retentions directly to an agreed upon designated escrow agent at the Contractor’s expense. If the Contractor selects either one of these alternatives, the following shall control.

9-3.2.5.1 Substitution of Securities for Performance Retention

At some reasonable time before any progress payment would otherwise be due and payable to the Contractor in the performance of Work under these Contract Documents, the Contractor may submit a request to the City in writing to permit the substitution of retentions with securities equivalent to the amount estimated by the City (“estimated amount of retention”) to be withheld.

12100-0001\2410807v2.doc City GP-52 of MB Form

The Contractor shall deposit such securities with the City or may, in the alternative, deposit such securities in escrow with a State or federally chartered bank in California, as the escrow agent, at the Contractor’s expense. Such securities will be the equivalent or greater in value of the estimated amount of retention. If the Contract is modified by written Modifications or Change Orders or the Contractor otherwise becomes entitled to receive an amount more than the Contract Price at the time the securities are deposited, the Contractor shall, at the request of the City, deposit with the City or escrow agent, whichever is applicable, additional securities within a reasonable time so that the amount of securities on deposit with the City or escrow agent is equivalent or greater in value than the amount of retention the City would otherwise be entitled to withhold from progress payments due or to become due to the Contractor as the Work progresses. The City shall withhold any retention amount that exceeds the security amount until the additional securities are deposited and, if the deposit is with an escrow agent, the City has confirmation from that escrow agent of the new total value of securities. Upon satisfactory completion of the Contract, which shall mean, among other things, that the City is not otherwise entitled to retain proceeds from progress payments as elsewhere provided in the Contract or under applicable law, the securities shall be returned to the Contractor. The City shall, within its sole discretion, determine whether the amount of the securities on deposit with the City or escrow agent is equal to or greater than the amount of estimated retention of progress payments that could otherwise be held by the City if the Contractor had not elected to substitute same with securities.

9-3.2.5.2 Deposit of Retention Proceeds with an Escrow Agent

As an alternative to the substitution of securities, as provided above, or the City otherwise retaining and holding retention proceeds from progress payments, the Contractor may request the City to make payments of retentions earned directly to an escrow agent with the same qualifications as required in Section 9-3.2.5.1 above and at the expense of the Contractor. At its sole expense, the Contractor may direct the investment of such retention payments into only such securities as mentioned in Section 9-3.2.5.3 below and shall be entitled to interest earned on such investments on the same terms provided for securities deposited by the Contractor. Upon satisfactory completion of the Contract, which shall mean when the City would not otherwise be entitled to withhold retention proceeds from progress payments had the Contractor not elected to have such proceeds deposited into escrow, the Contractor shall be allowed to receive from the escrow agent all securities, interest and payments deposited into escrow pursuant to the terms of this Section. The Contractor shall pay to each Subcontractor, not later than ten Days of receipt of payment, the respective amount of interest earned, net of costs attributed to retention withheld from each Subcontractor, on the amount withheld to ensure performance of the Contractor.

9-3.2.5.3 Subcontractor Entitlement to Interest

If the Contractor elects to receive interest on any moneys withheld in retention by the City, then the Subcontractor shall receive the identical rate of interest received by the Contractor on any retention moneys withheld from the Subcontractor by the Contractor, less any actual pro rata costs associated with administering and calculating that interest. In the event that the interest rate is a fluctuating rate, the rate for the Subcontractor shall be determined by calculating the interest rate paid during the time that retentions were withheld from the Subcontractor. If the Contractor elects to substitute securities in lieu of retention, then, by mutual consent of the Contractor and the Subcontractor, the Subcontractor may substitute securities in exchange for the release of moneys held in retention by the Contractor. The Contractor shall pay each Subcontractor, not later than ten Days after receipt of escrow moneys, the amount owed to each Subcontractor from the moneys plus the respective amount of interest earned, net of costs

12100-0001\2410807v2.doc City GP-53 of MB Form

attributed to the retention held from each Subcontractor, on the amount of retention withheld to ensure performance of the Subcontractor.

9-3.2.5.4 Securities Eligible for Investment

Securities eligible for investment shall include those listed in Government Code Section 16430, bank or savings and loan certificates of deposit, interest-bearing demand deposit accounts, standby letters of credit, or any other security mutually agreed upon between the Contractor and the City. The Contractor shall be the beneficial owner of any securities substituted for any monies withheld and shall receive any interest thereon.

9-3.2.5.5 Escrow Agreement for Security Deposits in Lieu of Retention

The escrow agreement that shall be used for the deposit of securities in lieu of retention shall substantially conform to the form prescribed in Public Contract Code Section 22300(f).

9-3.2.5.6 Inconsistencies with Prevailing Statutory Requirements

If there is any inconsistency between or differences in Public Contract Code Section 22300 and the terms of this provision, or any future amendments thereto, Section 22300 shall control.

9-4 AUDIT

The City or its representative shall have the option of inspecting and/or auditing all records and other written materials used by the Contractor in preparing its billings to the City as a condition precedent to any payment to the Contractor or in response to a construction claim or a Public Records Act (Government Code Section 6250 et seq.) request. The Contractor will promptly furnish documents requested by the City at no cost. Additionally, the Contractor shall be subject to State Auditor examination and audit at the request of the City or as part of any audit of the City, for a period of three and one-half years after Final Acceptance under the Contract. The Contractor shall include a copy of this Section 9-4 in all contracts with its Subcontractors, and the Contractor shall be responsible for immediately obtaining those records or other written material from its Subcontractors upon a request by the State Auditor or the City. If the Project includes other auditing requirements, those additional requirements will be listed in the Special Provisions.

• “Infeasibility Exemption Approved”

The Contractor shall follow the WMP and document results during demolition and construction. Final documentation shall be submitted at the end of the project to the Engineer for review of compliance with the original WMP. The amount deducted from the final estimate and retained by the City in accordance with Section 9.3.1 and 9.3.2 shall be withheld until final WMP is submitted to the City and approved by the City.

10-2 DEFINITIONS

a) “Construction” means the building of any facility or structure or any portion thereof including any tenant improvements to an existing facility or structure.

b) “Construction and Demolition Debris” means used or discarded materials removed from premises during construction of the Project.

c) “Conversion Rate” means the rate set forth in the standardized Conversion Rate Table approved by the City Council pursuant to this Section for use in estimating the volume or weight of materials identified in a Construction and Demolition Waste Reduction and Recycling Plan.

d) “Divert” means to use material for any purpose other than disposal in a landfill. Diversion credit is given for source reduction (waste reduction), recycling, and composting.

e) “Diversion Requirement” means the diversion of at least 65% of the total Construction and Demolition Debris generated by a Project via reduction (source reduction), reuse or recycling, unless the Contractor has been granted an Infeasibility Exemption, in which case the Diversion Requirement shall be the maximum feasible diversion rate established by the Engineer.

f) “Recycling” means the process of collecting, sorting, cleansing, treating, and reconstituting materials that would otherwise become solid waste, and returning them to the economic mainstream in the form of raw material for new, reused, or reconstituted products which meet the quality standards necessary to be used in the marketplace.

g) “Renovation” means any change, addition, or modification in an existing structure.

h) “Reuse” means further or repeated use of Construction or Demolition Debris. An example is the reuse of crushed concrete as road base or as aggregate on the construction site.

The Contractor shall indicate on the WMP the maximum rate of diversion the Contractor believes is feasible for each material and the specific circumstances that the Contractor believes make it infeasible to comply with the Diversion Requirement. b) The Engineer shall review the information supplied by the Contractor and may meet with the Contractor to discuss possible ways of meeting the Diversion Requirement. Based on the information supplied by the Contractor, the Engineer shall determine whether it is possible for the Contractor to meet the Diversion Requirement. c) If the Engineer determines that it is infeasible for the Contractor to meet the Diversion Requirement due to unique circumstances, the Engineer shall determine the maximum feasible diversion rate for each material and shall indicate this rate on the WMP submitted by the Contractor. The Engineer shall return a copy of the WMP to the Contractor marked “Infeasibility Exemption Approved.” d) Denial of Exemption. If the Engineer determines that it is possible for the Contractor to meet the Diversion Requirement, the Engineer shall so inform the Contractor in writing. The Contractor will have 15 days to resubmit a new WMP. If the Contractor fails to resubmit a new WMP, or if the resubmitted WMP does not comply with the requirements of the plan, the Engineer shall deny the WMP.

10-4 DIVERSION PROGRAM

The methodology used to calculate diversion is based on the Title 14, California Code of Regulations, Article 6.1 Solid Waste Generation Study, Section 18722 et seq, and is consistent with California Integrated Waste Management Board measurement protocols.

During all concrete pouring and tile installation procedures, ensure adequate safety guidelines are in place and that they are in accordance with the applicable industry and government standards. The physical characteristics of the concrete shall be consistent with the contract specifications while maintaining a slump range of 4” – 7” to permit solid placement of the Cast-In-Place Tile System. An overly wet mix will cause the Cast-In-Place System to float, therefore under these conditions suitable weights such as 2 concrete blocks or sandbags (25 lbs) shall be placed on each tile. Prior to placement of the Cast-In-Place System, the contract drawings shall be reviewed by the Engineer. The concrete pouring and finishing operations require typical mason’s tools, however, a 4’ long level with electronic slope readout, 25 lb weights, vibrator and small sledge hammer with 2” x 6” x 20” wood tamping plate are specific to the installation of the Cast-In-Place System. The concrete shall be poured and finished, true and smooth to the required dimensions and slope prior to tile placement. Immediately after finishing the concrete, the electronic level should be used to check that the required slope is achieved. The tile shall be placed true and square to the curb edge in accordance with the contract drawings. The Cast-In-Place Tiles shall be tamped or vibrated into the fresh concrete to ensure that the field level of tile is flush to the adjacent concrete surface. While concrete is workable a steel trowel shall be used to trowel the concrete around the tile perimeter of the field level of the tile. During and after the tile installation and the concrete curing stage, it is imperative that there is no

12100-0001\2410807v2.doc City TP-30 of MB Form

walking, leaning or external force placed on the tile to rock the tile, causing a void between the underside of the tile and concrete. Following tile placement, review installation tolerances to contract drawings and adjust tile before the concrete sets, 2 suitable weights of 25 lb each shall be placed on each tile as necessary to ensure solid contact of tile underside of concrete. Following the curing of the concrete, the protective plastic wrap is to be removed from the tile face by cutting the plastic with a sharp knife tight to the concrete/tile interface. If concrete bleeding occurs, a wire brush will clean the residue without damage to the tile surface. 303-5.7 Repairs and Replacements

Our scope of services did not include evaluations or recommendations regarding groundwater quality, hazardous waste, asbestos or lead abatement, or demolition of existing structures, utilities, or other facilities.

1.2 Project Description and Background

The City plans to widen the west side of Aviation Boulevard and north side of Artesia Boulevard to provide a southbound Aviation to Westbound Artesia Right-turn lane. Additional right-of-way is required on both Aviation Boulevard and Artesia Boulevard. A retaining wall of various heights (maximum 7-foot high) at the northwest corner of the intersection is needed. A storm catch basin and connector pipe need to be added adjacent to the end of curb return to drain the proposed sump in the curb and gutter.

2.0 FIELD EXPLORATION

Prior to the field investigation, a site reconnaissance was performed by our staff to mark the boring location and to evaluate this location with respect to utility lines and other subsurface structures. Underground Service Alert was then notified for the proposed boring location (Ticket number A70940854). The field investigation was performed on April 7, 2017 and consisted of drilling two (2) borings (Borings B-1 and B-2) to a maximum depth of 4 feet below ground surface (bgs) in the planter area, and two (2) borings (Borings B-3 and B-4) to a maximum depth of 16.5 feet bgs on Aviation Boulevard close to the intersection with Artesia Boulevard. Boring location, tentative depth, and soil sampling intervals were specified by Michael Baker International, Inc. and the project geotechnical engineer based on the anticipated subsurface conditions.

The two (2) 4-foot deep borings (Borings B-1 and B-2) were drilled with hand auger drilling equipment. Bulk samples were retrieved from the upper four (4) feet of onsite soils at the drilling location. A Modified California (MC) ring sampler for hand auguring was used to collect relatively undisturbed samples at a depth of approximately 2.5 feet bgs.

The two (2) 16.5-foot deep borings (Borings B-3 and B-4) were drilled with an 8-inch outside diameter hollow-stem auger (HSA) on a truck-mounted drill rig. 2R Drilling from Chino, California was subcontracted to drill the borings under the field supervision of HAI personnel. In order not to interfere with any utilities at the proposed drilling location, the upper five (5) feet of onsite soils were drilled using hand auger drilling equipment. Bulk samples were retrieved from the upper five (5) feet of onsite soils at the drilling location. From five (5) feet to the maximum drilling depth, relatively undisturbed samples were recovered from the test borings. Samples were taken at about every 5 feet using a Modified California (MC) ring sampler. The MC sampler has a 2.42-inch inside diameter and a 3.0-inch outside diameter and was used to collect relatively undisturbed samples.

After the sampler was withdrawn from the boring, soil samples were carefully removed, visually inspected and classified according to the Unified Soil Classification System (USCS), sealed to reduce moisture loss, and delivered to our laboratory for further inspection, soil classification, and testing. The borings were backfilled with compacted soil cuttings upon completion of the field investigation. The pavement surface at the locations of Borings B-3 and B-4 was patched with cold asphalt concrete.

Page 2 MBI-17-001 Michael Baker International Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Lane Improvement Project

Approximate location of the exploratory borings are shown on Figure 1. Logs of exploratory borings, as well as a key to these logs, are presented in Appendix A.

3.0 LABORATORY TESTING

Soil samples collected during the field investigation were examined in our laboratory and selected samples were tested to evaluate their physical characteristics, in-situ conditions, classification, index, and engineering properties. Laboratory tests performed included: • In-Situ Moisture Content and Dry Density (ASTM D2937); • Particle-Size Analysis of Soils (ASTM D6913); • Expansion Index (ASTM D4829); • Direct Shear (ASTM D3080); • R-Value (CTM 301); and • Corrosion Potential (including minimum resistivity, pH, soluble sulfates and soluble chlorides tests, in accordance with ASTM G187, CTM 643, 417 and 422).

Classifications made in the field were modified as appropriate based on the laboratory test results. These modifications and the type of tests performed on the selected soil samples are reflected in boring logs in Appendix A. Laboratory test results are presented in Appendix B.

4.0 SITE CONDITIONS

4.1 Local Geology

According to the California Geological Survey (CGS) Seismic Hazard Zone Report for the Redondo Beach 7.5-Minute Quadrangle (CGS, 2006), the project site is located in a region with late Pleistocene marine terrace deposits (Qter), mapped in places as Qoa, generally consisting of silty sand with local gravels that are found throughout the Palos Verdes Peninsula. Regional geology is presented in Figure 2.

4.2 Surface and Subsurface Conditions

Table 1 summarizes the thicknesses of the existing pavement structural sections and R-value test results for Borings B-3 and B-4. The log of borings in Appendix A also provides a graphical depiction of the existing pavement section and soil type.

Page 3 MBI-17-001 Michael Baker International Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Lane Improvement Project

According to the USCS, soils along the exploration depth at the four (4) boring locations classify as Well-graded or Poorly graded Sand (SW or SP) and Silty Sand (SM). Based on laboratory test results, the in-place moisture content of the samples collected at varies between approximately 5 and 11 percent. Similarly, the in-place dry unit weight of the soil varies between approximately 84 and 125 pounds per cubic feet (pcf).

4.3 Groundwater

Groundwater was not encountered in any of the borings. According to the groundwater map for the Redondo Beach Quadrangle (CGS, 2006), the historical highest groundwater depth at the project site is greater than 10 feet bgs. However, groundwater levels may fluctuate due to seasonal variation, nearby construction, irrigation, and numerous other anthropogenic and natural influences. The groundwater contour map is presented in Figure 3.

4.4 Expansion Potential

According to the 2016 California Building Code (CBC), if the expansion index is greater than 20, soils are considered expansive. Based on the result of one (1) Expansion Index test (ASTM D4829) performed on a soil sample collected within the upper 5 feet at the location of Boring B-4, the near- surface soils at this location have an expansion index value of 0 and are considered non-expansive.

4.5 Corrosion Potential

Two (2) samples collected within the upper 5 feet were submitted to Project X Laboratory for pH, minimum resistivity, soluble sulfates and soluble chlorides content testing. The results of the tests are summarized in Table 2. Details of the test results are presented in Appendix B.

Table 2. Results of Corrosivity Testing Estimated Estimated Boring/ Corrosivity Corrosivity Depth Chloride Sulfate Resistivity Based on Sample (feet) (mg/kg)1 (mg/kg) 1 pH Based on No. (ohm-cm) Resistivity2 Sulfates3 B-2/ Mildly Bulk 1 0-4 30 30 8.65 6,968 Corrosive S0 B-4/ Very Mildly Bulk 4 1-5 39 60 7.76 16,750 Corrosive S0 Notes: 1. mg/kg = milligrams per kilogram (parts per million) of dry soil. 2. The approximate relationship between soil resistivity and soil corrosivity was developed based on the findings of studies presented in ASTM STP 1013 titled “Effects of Soil Characteristics on Corrosion” (February, 1989). 3. The approximate relationship between water-soluble sulfate (SO4) in soil (percent by weight) and soil corrosivity was developed based on the 2013 California Building Code (CBC), referring to ACI 318M-14.

The above tests were performed for screening purposes only. Our firm does not practice corrosion engineering; therefore, we recommend that a corrosion engineer be retained to evaluate the corrosion potential of the onsite soils and any impact on the proposed project structures.

5.0 SEISMIC DESIGN CONSIDERATIONS

5.1 Seismic Design Coefficients and Site Seismicity

The seismic design coefficients based on Chapter 11 of the ASCE 7-10 are provided in Table 3.

Table 3. Site Categorization and Site Coefficients Design Categorization/Coefficient Value* 33.87306°N Site Coordinates 118.38157°W Site Soil Classification SD Short Period Spectral Acceleration SS (g) 1.610 1-sec. Period Spectral Acceleration S1 (g) 0.606 Short Period (MCER) Spectral Acceleration SMS (g) 1.610 1-sec. Period (MCER) Spectral Acceleration SM1 (g) 0.909 Short Period Design Spectral Acceleration SDS (g) 1.073 1-sec. Period Design Spectral Acceleration SD1 (g) 0.606

Note: MCER stands for Risk-Targeted Maximum Considered Earthquake. * Values obtained from USGS U.S. Seismic Design Maps tool, based on 2010 ASCE 7 Standard with March 2013 errata, http://earthquake.usgs.gov/designmaps/us/application.php?

Based on the number of blow counts measured in our borings and the results of laboratory tests, the site classification was assumed as Site Class SD. The Mapped Peak Ground Acceleration (PGAM) adjusted for site effects at the sites was calculated to be 0.612g.

The Compton and Palos Verdes Fault Zones are located about 6.5 km south of the site. Other active faults within the project area include the Redondo Canyon alt 1 Fault Zone, located at approximately 6.9 km to the southwest of the project site, and the North Los Angeles Basin Section of Newport Inglewood Fault Zone, located approximately 9.5 km to the northeast of the project site.

5.3 Fault Rupture Hazards

Primary ground rupture is ground deformation that occurs along the surface trace of an active fault during an earthquake. CGS defines an active fault as one that has experienced surface rupture within the last approximately 11,000 years (Holocene time). According to CGS Special Publication 42 (1997a), the proposed improvements are not located within an Alquist-Priolo Earthquake Fault Zone. The site fault activity map is presented on Figure 4. No known surface expression of active faults is believed to exist within the site. Based on the above mentioned reference, the potential for a fault rupture through the site is considered low.

Page 5 MBI-17-001 Michael Baker International Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Lane Improvement Project

5.4 Liquefaction

Soil liquefaction results in loss of strength during cyclic loading, such as imposed by earthquakes. Soils most susceptible to liquefaction are loose to moderately dense, saturated granular soils with poor drainage, such as silty sands or sands and gravels capped by or containing seams of impermeable sediment or non-plastic fine-grained soils. When seismic ground shaking occurs, the cohesionless soil is subjected to cyclic shear stresses that can cause increased pore water pressure that induces liquefaction. Liquefaction can cause softening and large cyclic deformations. In loose granular soils, softening can also be accompanied by a loss of shear strength that may lead to large shear deformations or even flow failure under moderate to high shear stresses, such as beneath a foundation or sloping ground (NCEER/NSF, 1998). Loose granular soil can also settle (densify) during liquefaction and as pore pressures dissipate following an earthquake.

According to the CGS Seismic Hazard Map for the Redondo Beach 2006 (CGS, 2006), the project site is not located within liquefaction-prone areas (see Figure 5). Therefore, a liquefaction potential analysis in accordance with the “Guidelines for Evaluating and Mitigating Seismic Hazards in California” Special Publication 117A of the CGS (formerly the Division of Mines and Geology) (CGS, 2008) was not performed for this project.

5.5 Landslides

The subject of landslides is a widely encompassing subject and cannot be fully covered in a brief summary; however, landslides are downslope motions of conglomerations of earth materials or bedrock or combinations of both. Landslides are a more defined unit and are similar to slumps, but are on a larger scale. They can move in a translational movement or rotational settlement or motion. It occurs because of the loss of ability of earth materials to maintain their integrity at a specific gradient and settle or deform into a lesser gradient or position of greater equilibrium. The internal strength of the material is lost and the material settles into a form where the mass is centralized on the downhill side of motion. Landslides are usually associated with water increasing the unit weight and decreasing the internal strength of the materials. The chances of a landslide occurring are increased by increases in slope gradient, looseness of materials, unfavorable bedding (out of slope), clay content of the bedrock, underground springs, unfavorable slope orientation with existing fault boundaries, human disturbance of the landslide or its boundaries, rise of groundwater, earthquake forces helping to mobilize the mass, looseness of in-situ materials, increases in water content, and disturbance of the lateral confining forces and/or the toe of a slope.

According to the CGS Seismic Hazard Map for the Redondo Beach Quadrangle (CGS, 2006), the project site is not located in earthquake-induced landslide areas (see Figure 5) and landslide is not expected to be an issue.

6.0 CONCLUSIONS AND RECOMMENDATIONS

The discussions and recommendations presented in the following sections are based on our understanding of the proposed project requirements, the results of our geotechnical investigation, and our professional judgment.

Page 6 MBI-17-001 Michael Baker International Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Lane Improvement Project

It is our opinion that based on the above-cited geotechnical findings, the site is suitable for construction of the proposed improvements, provided that the recommendations in this report are followed, and onsite construction observations and field testing are performed.

6.1 Site Preparation and Shoring Requirements

Prior to construction, the site should be cleared of all above-ground obstacles and structures. Existing utility and irrigation lines should be protected in-place, rerouted, or removed if they interfere with the proposed construction. The resulting cavities from removal of utility lines should be properly backfilled and compacted under the supervision of the project geotechnical engineer. Vegetation, debris, and organic matter should not be incorporated into the structural fill.

Excavations deeper than 4 feet should be either laid back or shored according to appropriate jurisdiction guidelines before personnel are allowed to enter. In addition, special care should be taken for excavations near existing improvements to ensure that their integrity is not impacted. For pipes where the pipe invert depths are greater than 4 feet, wherever there is an apparent physical restriction on the lateral land for trench layback, shoring is recommended. This also applies to shallow excavations where the depth of the excavation is equal or less than 4 feet.

Trenching should be performed in short (less than 200 feet) sections. Each 200-foot section should be properly shored prior to excavation of the next segment. Long-term storage of excess earth material or equipment along the top of the excavation should be avoided within a 1H: 1V (horizontal: vertical) projection from the base of the trench.

Typical cantilever shoring should be designed based on an active fluid pressure of 43H psf. If excavations are braced at the top and at specific design intervals, the shoring pressure may then be approximated by a rectangular soil pressure distribution with a pressure per foot of width equal to 33H (psf), where H is equal to the depth of the excavation being shored.

The project geotechnical engineer should review the contractor’s shoring design prior to implementation. In addition to the abovementioned pressures, the shoring system must be designed to resist horizontal pressures that may be generated by surcharge loads applied at the ground surface such as from uniform loads or vehicle loads. The edges of all excavations should be kept away from the property line a minimum horizontal distance equal to 2H (where H is the height of the excavation) or as set forth by local ordinances, whichever is more strict.

6.2 Lateral Earth Pressure for Retaining Structures

Based on laboratory test results and encountered soil conditions, the recommended lateral earth pressures are shown below:

Page 7 MBI-17-001 Michael Baker International Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Lane Improvement Project

Table 4. Recommended Lateral Earth Pressures Design Parameter Design Value

Active Pressure (Pa) 0.36q + 43H At-Rest Pressure (Po) 0.53q + 64H

Passive Pressure (Pp) 270H (maximum 2,700 psf) 2 Fe = 16H Seismic Force (Fe) (for cantilever walls, expect some deformations) Coefficient of Friction (µ) 0.34 Notes: 1. All Design Values were calculated based on zero cohesion, an internal friction angle of 28°, and a unit weight of 120 pcf. The coefficient of friction was calculated with a safety factor of 1.5. 2. All values of height (H) in feet (ft), pressure (P) and surcharge (q) in pounds per square feet (psf) and force (F) in pounds (lb) are for unit width of walls. 3. The above pressure values apply to horizontal backfill and do not include hydrostatic pressures that might be caused by groundwater or water trapped behind the structure. 4. For 2:1 and 3:1 slopes above the wall, increase Pa and Po by 80 and 35 percent, respectively. 5. µ is the friction coefficient applied to dead normal (buoyant) loads. Fe is in addition to the active and at-rest pressures, Pa and Po. 6. For passive pressure use a factor of safety of 2.5 if wall rotation (D/H) is smaller than 0.04. The passive pressure might not be used if soil is subjected to scour. 7. Neglect the upper 1 foot for passive pressure unless the surface is contained by pavement or a slab. 8. The earthquake load (Fe) should be distributed as a triangle along the wall height. 9. In addition to the abovementioned pressures, retaining walls must be designed to resist horizontal pressures that may be generated by surcharge loads applied at the ground surface such as from uniform loads or vehicle loads. 10. An equivalent mapped ground acceleration of 0.31g (½ of PGAM) was used to calculate Fe for the Design Earthquake. The earthquake load (Fe) may be distributed as an inverted triangular along the wall height for restrained or cantilever conditions.

An efficient drainage system should be provided behind retaining walls, which should consist of a curtain of free-draining material, such as Caltrans permeable Class 2 Aggregate. This drain curtain should be a minimum of 2 feet wide and extend from the bottom of the wall to within 1.5 feet of finish grade. Additionally, drainage geocomposite (Miradrain or equivalent) should be used to wrap the gravel material. The upper 1.5 feet should be a select material of low permeability (clayey soil) to minimize infiltration. A perforated pipe should be placed along the base of the wall and should be sloped at least two percent to drain water by gravity to a suitable discharge facility.

6.3 Foundations

Relatively light structures could be supported on continuous or spread footings bearing on 3 feet of compacted clean “granular” soils (soils having less than 20 percent passing standard sieve #200, free of debris, vegetation, and with rocks less than 6 inches in diameter with no more than 15 percent greater than 3 inches in diameter, confirmed with laboratory testing prior to construction) and extending to a zone of 3 feet beyond the edge of the footings, compacted in 8-inch-thick lifts (measured in loose state) to a minimum of 90 percent relative compaction per ASTM D1557 (Modified Proctor, latest edition).

Page 8 MBI-17-001 Michael Baker International Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Lane Improvement Project

Prior to placing any clean “granular” soil, the upper 18 inches of the excavation bottom should be scarified, moisture-conditioned to approximately 2 percent above the optimum moisture content, and recompacted to at least 90 percent of the maximum dry density per ASTM D1557 (Modified Proctor Test, latest edition). Based on laboratory test results, an allowable bearing capacity of 2,500 pounds per square foot may be used for design of 24-inch wide continuous footings embedded a minimum of 18 inches below adjacent level ground. This value may be increased by 250 and 500 pounds per square foot for every additional foot of width or depth increase, respectively, to a maximum of 3,500 pounds per square foot.

A lateral passive soil resistance on footing walls embedded in compacted engineered fill of 270 psf per foot of depth below the lowest adjacent finished grade, to a maximum of 2,700 psf, may be used for design. This lateral passive resistance may be combined with a lateral base friction resistance. A base friction coefficient of 0.34 may be used. The coefficient of friction should be multiplied by the dead load to obtain the lateral base friction resistance.

Where footings are adjacent to below-grade walls or underground utilities, the footings should extend below a 45-degree plane projected upward from the backside of the wall footing or bottom of the underground utility. Structural loads were not available at the time of our investigation. We should be retained to review the final foundation plans and structural loads for soil settlement estimation.

6.4 Pavement Design

Based on R-value test results from representative subgrade soil samples collected during the field investigation, Table 5 presents our recommendations for minimum pavement structural sections for traffic index (TI) values from 6 to 12.

Table 5. Recommended Pavement Section (Design R-value = 60)

Traffic Index (TI) Alternative Pavement Sections 6.0 7.0 8.0 9.0 10.0 11.0 12.0

Hot-Mix Asphalt (HMA) over 4.0” 4.5” 5.5” 6.0” 7.0” 7.5” 8.0” Aggregate Base (AB)* 4.5” 4.5” 4.5” 4.5” 4.5” 4.5” 4.5”

Full Depth Hot-Mix Asphalt (HMA) 4.5’’ 5.5’’ 6.5’’ 7.5” 8.5” 9.5” 10.0”

* Caltrans Class 2 aggregate base; minimum R-Value equal to 78.

The recommendations provided below are considered general and should be complemented with latest editions of Caltrans’ Highway Design Manual (HDM) and the Standard Specifications of Public Work Construction “Greenbook”, including all subsequent amendments, supplements and additions. In case of a conflict, the most stringent recommendations should prevail.

Page 9 MBI-17-001 Michael Baker International Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Lane Improvement Project

Subgrade Preparation: Upon removal of the pavement, the subgrade surface should be observed by the geotechnical engineer to verify that suitable competent bearing soil is exposed. The top 12 inches of the subgrade soil should then be scarified, brought to 2 to 3 percent above optimum moisture content and re-compacted to a minimum of 90 percent relative compaction in accordance with ASTM D1557, latest version. Unsuitable materials encountered during grading should be removed to the satisfaction of the geotechnical engineer and replaced with aggregate base or other materials approved by the geotechnical engineer.

Aggregate Base (AB): In all cases, AB should be in accordance with Class 2 AB per Caltrans’ Standard Specifications (latest edition). AB material should be compacted in 6-inch thick lifts to a minimum of 95 percent relative compaction per ASTM D1557, latest edition.

Hot Mix Asphalt (HMA): HMA should be compacted to a minimum of 95 percent of the HMA density determined by ASTM D1561 test procedure (latest version) in lifts not exceeding 3 inches. A “tack coat” should be applied between HMA layers.

Special recommendations:

1. Subgrade, AB, and HMA for future curbs, gutters, and sidewalks should also be worked following the above mentioned recommendations.

2. In all cases we recommend designing an efficient drainage system by the Civil Engineer of the project in order to avoid the adverse effects of surficial water penetrating into the pavement structural section. It is important to highlight that poor drainage is by far the most detrimental geotechnical factor for asphalt concrete pavement roads because it adversely contributes to degrading the stiffness and strength of the unbound (non- bituminous) materials the structural section is comprised of.

6.5 Pipelines

6.5.1 Pipe Zone Bedding and Shading Backfill

Pipe bedding should extend to a depth of at least 6 inches or pipe manufacturer’s recommendation below the pipeline invert and the shading should extend from the top of the bedding to a height of at least 12 inches over the top of the pipe or pipe manufacturer’s recommendation. In addition, there should be a minimum range of 6 to 8 inches of pipe zone backfill material on either side of the pipe or pipe manufacturer’s recommendation.

The bedding and shading material may consist of compacted, free draining sand, gravel, or crushed rock, having a sand equivalent of not less than 30, and meeting the gradation and compaction requirements of the Greenbook, latest edition, or pipe manufacturer’s recommendation. If open grade rock or crushed slag base is used around the pipe and within any portion of trench backfill, it should be separated from surrounding finer-grained material by installation of a geo-filter fabric. Properties of the pipe zone bedding and shading material should be confirmed with laboratory testing prior to construction. Onsite soils are not recommended to be used as pipe zone bedding or shading backfill.

Page 10 MBI-17-001 Michael Baker International Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Lane Improvement Project

The bedding material should be compacted to a minimum relative compaction of 90 percent per ASTM D1557 (Modified Proctor). Backfilling should be carried on simultaneously on each side of the pipe to ensure proper protection of the pipe. The bedding layer should be supported on firm, competent material, as determined by the project geotechnical engineer. Disturbed, loose/soft materials at the excavation bottom should be removed to expose firm native material per the project geotechnical engineer recommendations. If firm material is not encountered, the upper 1 foot of the onsite soils below the pipe bedding should be scarified, moisture-conditioned to approximately 2 percent above the optimum moisture content, and recompacted to at least 90 percent of the maximum dry density per ASTM D1557 (Modified Proctor). If compaction of the native soils below the bedding material is not feasible at any location, a 12-inch thick layer of crushed rock wrapped in geofabric should be placed below the pipe bedding. Questionable areas should be reviewed individually by the project geotechnical engineer to evaluate and recommend corrective measures, as necessary.

Placement of bedding and shading backfill should be observed by the project geotechnical engineer or his representative in the field and tested for compliance with the recommended relative compaction and moisture conditions.

Field density testing should conform to ASTM D6938 (Nuclear Method) and D1556 (Sand Cone Method), latest editions. Tests should be taken at a minimum of every 2 vertical feet of fill placed and every 200 feet of length, or at a frequency otherwise specified by the local regulations, whichever is stricter. Actual test intervals may vary with field conditions. Backfill found not to be in conformance should be removed or recompacted as recommended by the project geotechnical engineer.

Densification by water jetting within the pipe bedding and shading zone is not recommended. During removal of the shoring system, gaps should be filled and compacted. Pipes that are deeper than 5 feet should be able to handle stresses due to moving traffic. Casing of the pipeline might be necessary if pipes are placed shallower than 5 feet.

6.5.2 Trench Zone

Non expansive clean “granular” soils (confirmed with laboratory testing prior to construction) may be used as compacted structural fill, provided they are free of organic material, construction debris, and not containing rocks greater than 6 inches in diameter, with no more than 15 percent rocks greater than 3 inches in diameter. Clean “granular” soils should be placed in thin, loose lifts not more than 8 inches in thickness, moisture-conditioned to approximately 2 percent above the optimum moisture content and compacted to at least 90 percent of the maximum dry density per ASTM D1557 (Modified Proctor). For pavement areas, the upper 12 inches of the trench zone should be moisture-conditioned to approximately 2 percent above the optimum moisture content and compacted to at least 95 percent of the maximum dry density per ASTM D1557 (Modified Proctor). Onsite soils meeting these requirements may be used as trench zone backfill.

Placement of backfill should be observed by the project geotechnical engineer or his representative in the field and tested for compliance with the recommended relative compaction and moisture conditions.

Page 11 MBI-17-001 Michael Baker International Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Lane Improvement Project

Field density testing should conform to ASTM D6938 (Nuclear Method) and D1556 (Sand Cone Method). Tests should be taken at a minimum of every 2 vertical feet of fill placed and every 200 feet of length, or at a frequency otherwise specified by the local regulations, whichever is stricter. Actual test intervals may vary with field conditions.

Backfill found not to be in conformance should be removed or recompacted as recommended by the project geotechnical engineer. Densification by water jetting within the trench zone is not recommended. During removal of the shoring system, gaps should be filled and compacted.

6.6 Existing Utilities

The proposed improvement locaitons located near to and/or cross several existing utilities. The contractor should exercise care not to disturb these utilities and to support them during construction. Compacting backfill above the pipe zone could be detrimental to surrounding utilities; we recommend a weak slurry mix (minimum compressive strength of 100 pound per square inch [psi]) to be used for the backfilling operations wherever soil compaction is not feasible. These areas should be limited to zones between two pipes and not exceeding 2 feet on either side of the crossing.

6.7 Site Drainage

The site should be graded to provide adequate drainage away from building foundations and to prevent ponding on pavements in accordance with guidelines established by the City, Greenbook (latest edition), and the 2016 CBC. Special surface drainage features should be incorporated to drain surface sheet flow of water from retaining walls and intercept sheet flow over the paved areas.

6.8 Construction Observations and Field Testing

Construction observations and field testing should be performed by representatives of a qualified geotechnical engineer to confirm that the conditions and assumptions described in this report are the best representation of the actual conditions.

At a minimum, we recommend that the geotechnical engineer and/or his representative be present to observe and test during the following construction activities:

• Excavation, site grading of cuts and fills; • Placement of all backfill; • Backfilling of utility trenches and pits; and • When any unusual conditions are encountered during grading.

Onsite observation and field testing will be a key component to a suitable geotechnical design for this project. A final report of grading should be submitted to the City.

7.0 ADDITIONAL SERVICES AND LIMITATIONS

7.1 Additional Services

If considerable modifications to the concepts included herein are implemented over the course of the design, specific geotechnical consultation and input will be required. Accordingly, we recommend that HAI be retained to provide such consultation during site preparation and grading on an as-needed basis. As a minimum HAI should be retained to review the grading and design plans prior to their issuance for conformance and compatibility with the recommendations presented in this report.

7.2 Limitations

This report has been prepared for the sole use of Michael Baker International, Inc., specifically for design of this project in Manhattan Beach, California. The opinions presented in this report have been formulated in accordance with existing accepted geotechnical engineering practices in the southern California at the time this report was written. No other warranty, expressed or implied, is made or should be inferred.

The opinions, conclusions and recommendations contained in this report are based upon the information obtained from our investigation, which includes data from widely separated discrete sampling locations, visual observations from our site reconnaissance, along with local experience and engineering judgment. The recommendations presented in this report are based on the assumption that soil and geologic conditions at or between borings do not deviate substantially from those encountered during our investigation. We are not responsible for the data presented by others. We should be retained to review the geotechnical aspects of the final plans and specifications for conformance with our recommendations. The recommendations provided in this report are based on the assumption that we will be retained to provide observation and testing services during construction to confirm that conditions are similar to that assumed for design and to form an opinion as to whether the work has been performed in accordance with the project plans and specifications.

If we are not retained for these services, HAI cannot assume any responsibility for any potential claims that may arise during or after construction as a result of misuse or misinterpretation of HAI’s report by others. Furthermore, HAI will cease to be the Geotechnical-Engineer-of-Record if we are not retained for these services and/or at the time another consultant is retained for follow up service to this report.

The opinions presented in this report are valid as of the present date for the site evaluated. Changes in the condition of the site will likely occur with the passage of time due to natural processes and/or the works of man. In addition, changes in applicable standards of practice can occur as a result of legislation and/or the broadening of knowledge. Furthermore, geotechnical issues may arise that were not apparent at the time of our investigation. Accordingly, the opinions presented in this report may be invalidated, wholly or partially, by changes outside of our control. Therefore, this report is subject to review and should not be relied upon after a period of three years, nor should it be used, or is it applicable, for any other properties.

SUBJECT: Phase I Environmental Site Assessment for the Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project, located in Manhattan Beach, California

Dear Mr. Prem Kumar,

Michael Baker International (Michael Baker), is pleased to submit this Phase I Environmental Site Assessment (ESA) for the above referenced project, herein referenced as the “subject site.” The goal of this Phase I ESA is to identify recognized environmental conditions (RECs) associated with the subject site. This Phase I ESA has been prepared for the sole use of the City of Manhattan Beach, for the above-referenced subject site. Neither this Phase I ESA, nor any of the information contained herein, shall be used or relied upon for any purpose by any person or entity other than the City of Manhattan Beach.

The Phase I ESA was prepared using methods consistent with the ASTM International (ASTM) E 1527-13 Standard Practice for Environmental Site Assessments, the scope of services, and inherent limitations presented in our proposal. The Phase I ESA is not intended to present specific quantitative information as to the actual presence of hazardous substances on or adjacent to the subject site, but is to identify RECs based on available information.

Should you or your staff have any questions or concerns after reviewing the enclosed report, please do not hesitate to contact me at 949/855-5747.

Sincerely,

Kristen Bogue Environmental Professional Planning/Environmental Services

SECTION 1.0 INTRODUCTION

1.1 PURPOSE

The purpose of conducting this Phase I Environmental Site Assessment (ESA) is to identify Recognized Environmental Conditions (RECs) as defined by the ASTM International (ASTM) E 1527-13 Standard Practice for Environmental Site Assessments (Standard Practice). The ASTM E 1527-13 Standard Practice defines the term REC as “the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to any release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment. De minimis conditions are not RECs.”

This Phase I ESA was conducted in accordance with the ASTM E 1527-13 Standard Practice and satisfies the requirements of 40 Code of Federal Regulations (CFR) Part 312 titled Standards and Practices for All Appropriate Inquiries, as required under Section 101(35)(B)(ii) and (iii) of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The purpose of conducting an All Appropriate Inquiries (AAI) investigation into the previous ownership and uses of a property is to meet the provisions necessary for the innocent landowner, contiguous property owner, or bona fide prospective purchaser to qualify for certain landowner liability protections under CERCLA. To assist in understanding the terminology contained in this Phase I ESA, a glossary of terms associated with the ASTM E 1527-13 Standard Practice is provided in Appendix A, ASTM Terminology.

1.2 DETAILED SCOPE OF SERVICES

This scope of work follows the ASTM E 1527-13 Standard Practice. The ASTM E 1527-13 Standard Practice outlines a procedure for completing Phase I ESAs that includes review of Federal, tribal, State, and local government records; site reconnaissance; interviews with current owners, operators, occupants, and government officials; and report preparation. This practice does not include any testing or sampling of materials (for example, soil, water, air, building materials, etc.). This Phase I ESA is not intended to provide specific qualitative or quantitative information as to the actual presence of hazardous substances at the subject site, but is to merely identify the potential presence based on available information.

1.3 SIGNIFICANT ASSUMPTIONS

Unless stated otherwise in this Phase I ESA, Michael Baker assumes that groundwater flow follows the topography of the subject site.

In lieu of reasonably available public information pertaining to groundwater contamination, Michael Baker assumes that potential groundwater plume dimensions are within the 90th percentile of plumes determined by research conducted as part of ASTM E 2600-10 Standard Guide for Vapor Encroachment Screening on Property Involved in real Estate Transactions, which described in detail in Table 1-1, Groundwater Plume Dimension Assumptions.

Buonicore, Methodology for Identifying the Area of Concern Around a Property Potentially Impacted by Vapor Migration from Nearby Contaminated Sources, Paper 2011-A-301-AWMA, June 2011.

1.4 LIMITATIONS, DEVIATIONS, AND EXCEPTIONS

Historical information for the subject site was obtained back to 1896, at which time the subject site consisted of transportation uses. Based on a review of available historical topographic maps, historical aerial photographs, and available public records, the subject site has consisted of transportation land uses and no other uses have been identified. Thus, it is the opinion of Michael Baker that this limitation is not a significant data gap at the time of this Phase I ESA.

No additional scope items, or items outside of the scope of a Phase I ESA E 1527-13 Standard Practice, were conducted as part of this Phase I ESA.

1.5 USER RESPONSIBILITIES

This Phase I ESA does not satisfy continuing obligations under CERCLA liability protections provided for innocent landowners, bona fide prospective purchasers, and contiguous property

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 1-2 Section 1.0 | Introduction

owners, which includes, but is not limited to, duties required after property acquisition (i.e., compliance with land use restrictions and institutional controls, undertaking “reasonable steps” with respect to hazardous substances releases, compliance with other obligations such as reporting obligations and information requests, etc.).

ASTM E 1527-13 Standard Practice defines the user as “the party seeking to use Practice E 1527 to complete an environmental site assessment of the property. A user may include, without limitation, a potential purchaser of property, a potential tenant of property, an owner of property, a lender, or a property manager.” The purpose of this section is to describe tasks to be performed by the user that will help identify the possibility of recognized environmental conditions in connection with the subject site. These tasks do not require the technical expertise of an environmental professional and are not required to be performed by environmental professional performing a Phase I ESA. The user questionnaire utilized within this Phase I ESA is optional to the user and aids the environmental professional in gathering information from the user that may be material to identifying RECs; refer to Section 2.0, User Provided Information, for a discussion of the User Questionnaire conducted as part of this Phase I ESA. It should be noted that the following tasks are required, by the user of this Phase I ESA, to satisfy the requirements of conducting all appropriate inquiries.

1.5.1 REVIEW TITLE AND JUDICIAL RECORDS FOR ENVIRONMENTAL LIENS OR ACTIVITY AND USE LIMITATIONS (AULS)

To meet the requirements of 40 CFR 312.20 and 312.25, a search for the existence of environmental liens and AULs that are filed or recorded against the property must be conducted. Environmental liens and AULs are legally distinct instruments and have very different purposes and both can commonly be found within recorded land title records (e.g., County Recorder/Registry of Deeds). The types of title reports that may disclose environmental liens and AULs include Preliminary Title Reports, Title Commitments, Condition of Title, and Title Abstracts. Chain of title reports will not normally disclose environmental liens or AULs. Environmental liens and AULs that are imposed by judicial authorities may be recorded or filed in judicial records only. In jurisdictions where environmental liens or AULs are only recorded or filed in judicial records, the judicial records must be searched for environmental liens and AULs. Any environmental liens and AULs known to the user should be reported to the environmental professional conducting a Phase I Environmental Site Assessment. Unless added by a change in the scope of work to be performed by the environmental professional (refer to Section 1.4, Limitations, Deviations, and Exceptions), this practice does not impose on the environmental professional the responsibility to undertake a review of recorded land title records and judicial records for environmental liens or activity and

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 1-3 Section 1.0 | Introduction

use limitations. The user should either (1) engage a title company or title professional to undertake a review of reasonably ascertainable recorded land title records and lien records for environmental liens or activity and use limitations currently recorded against or relating to the property, or (2) negotiate such an engagement of a title company or title professional as an addition to the scope of work to be performed by the environmental professional.

1.5.1.1 Reasonably Ascertainable Title and Judicial Records for Environmental Liens and Activity and Use Limitations

Environmental liens and AULs that are recorded or filed in any place other than recorded land title records are not considered to be reasonably ascertainable unless applicable Federal, tribal, State, or local statues, or regulations specify a place other than recorded land title records for recording or filing of environmental liens and AULs.

1.5.2 SPECIALIZED KNOWLEDGE OR EXPERIENCE OF THE USER

Users must take into account their specialized knowledge to identify conditions indicative of releases or threatened releases. If the user has any specialized knowledge or experience that is material to RECs in connection with the property, the user should communicate any information based on such specialized knowledge or experience to the environmental professional. The user should do so before the environmental professional conducts the site reconnaissance.

1.5.3 ACTUAL KNOWLEDGE OF THE USER

If the user has actual knowledge of any environmental lien or AULs encumbering the property or in connection with the property, the user should communicate such information to the environmental professional. The user should do so before the environmental professional conducts the site reconnaissance.

1.5.4 REASON FOR SIGNIFICANTLY LOWER PURCHASE PRICE

In a transaction involving the purchase of a parcel of commercial real estate, the user shall consider the relationship of the purchase price of the property to the fair market value of the property if the property was not affected by hazardous substances or petroleum products. The user should try to identify an explanation for a lower price which does not reasonably reflect fair market value if the property were not contaminated, and make a written record of such explanation. Among the factors to consider will be the information that becomes known to the user pursuant to the Phase I ESA. The ASTM E 1527-13 Standard Practice does not require that a

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 1-4 Section 1.0 | Introduction

real estate appraisal be obtained in order to ascertain fair market value of the property. The user should inform the environmental professional if the user believes that the purchase price of the property is lower than the fair market value due to contamination. The user is not required to disclose the purchase price to the environmental professional.

1.5.5 COMMONLY KNOWN OR REASONABLY ASCERTAINABLE INFORMATION

Commonly known or reasonably ascertainable information within the local community about the property must be taken into account by the user. If the user is aware of any commonly known or reasonably ascertainable information within the local community about the property that is material to recognized environmental conditions in connection with the property, the user should communicate such information to the environmental professional. The user should do so before the environmental professional conducts the site reconnaissance. The user must gather such information to the extent necessary to identify conditions indicative of releases or threatened releases of hazardous substances or petroleum products.

1.5.6 DEGREE OF OBVIOUSNESS

The user must consider the degree of obviousness of the presence or likely presence of releases or threatened releases at the property and the ability to detect releases or threatened releases by appropriate investigation including the information collected under the following sections within this Phase I ESA:

 Section 1.5.1, Review Title and Judicial Records for Environmental Liens and Activity and Use Limitations (AULs);  Section 1.5.2, Specialized Knowledge or Experience of the User;  Section 1.5.4, Reason for Significantly Lower Purchase Price;  Section 1.5.5, Commonly Known or Reasonably Ascertainable Information;  Section 3.2, Standard Environmental Records Sources;  Section 3.4, Historical Use Information on the Subject Site and Adjoining Properties;  Section 4.0, Site Reconnaissance; and  Section 5.0, Interviews.

1.5.7 OTHER

Either the user shall make known to the environmental professional the reason why the user wants to have the Phase I ESA performed or, if the user does not identify the purpose of the Phase

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 1-5 Section 1.0 | Introduction

I ESA, the environmental professional shall assume the purpose is to qualify for an LLP to CERCLA liability and state this in the report.

be required. Areas of acquisition consist of vacant land (paved driveway area and ornamental landscaping) associated with the off-site Chase Bank structure.

3.1.2 TOPOGRAPHY

The USGS maps show geological formations and their characteristics, describing the physical setting of an area through contour lines and major surface features including lakes, rivers, streams, buildings, landmarks, and other factors that impact the spread of contamination. Additionally, the maps depict topography through color and contour lines and are helpful in determining elevations and site latitude and longitude.

Based on the USGS Redondo Beach, California and Venice, California Quadrangles, both dated 2015, on-site topography is approximately 100 feet above mean sea level (msl) and slopes downgrade to the southeast. The subject site appears to consist entirely of developed land. Surrounding uses appear to consist of developed land and transportation land uses in Redondo Beach and Manhattan Beach. On-site roads include Aviation Boulevard and Highway 91. Developed areas of the City of Manhattan Beach border the subject site to the north. The Pacific Coast Highway (PCH) and the City of Hermosa Beach are visible to the west, Flagler Lane is visible to the east, and Rockefeller Lane is visible to the south. No on-site pits, ponds, or lagoons are noted on-site on these topographical maps.

3.1.3 CURRENT USES OF ADJOINING PROPERTIES

For the scope of this Phase I ESA, properties are defined and categorized based upon their physical proximity to the subject site. An adjoining property is considered any real property or properties the border of which is contiguous or partially contiguous with that of the subject site, or that would be contiguous or partially contiguous with that of the subject site but for a street, road, or other public thoroughfare separating them. The following is a detailed description of each adjoining land use observed on July 12, 2017:

 North: Aviation Boulevard extends north of the subject site. Commercial and residential uses are located north of the subject site.  East: Commercial land uses are located to the east of the subject site.  South: Artesia Boulevard bounds the southern portion of the subject site. Commercial and residential land uses are also located to the south of the subject site.  West: Artesia Boulevard extends to the west of the subject site. Commercial land uses are located to the west of the subject site.

3.1.4 GEOLOGIC CONDITIONS

3.1.4.1 Geology

The USGS Geological Map Index was searched by EDR for available Geological Maps that cover the subject site and surrounding areas. These Geological Maps indicate geological formations that are overlaid on a topographic map. Some maps focus on specific issues (i.e., bedrock, sedimentary rocks, etc.) while others may identify artificial fills (including landfills). Geological maps can be effective in estimating permeability and other factors that influence the spread of contamination.

According to the EDR GeoCheck Report, the land consists of a stratified sequence from the Cenozoic era. According to the Waterfront Draft Environmental Impact Report, dated July 2016, the project vicinity is located within the western coastal areas of the Los Angeles Basin (Basin), which is at the juncture of three Southern California physiographic provinces: the Transverse Ranges to the north, the Peninsular Ranges to the east and southeast, and the continental borderland to the west. The Basin is underlain by both marine and nonmarine accumulations of gravel, sand, silt, and clay that were deposited over time as a consequence of sea level fluctuations and erosion of the landmasses to the north, east, and south of the Basin.

3.1.4.2 Soils

According to the Waterfront Draft Environmental Impact Report, dated July 2016, the project vicinity was developed on active and inactive coastal sand dunes. In general, the coastal portion of the City within the Redondo Beach Quadrangle consists of surficial (surface) geologic deposits that are mostly artificial fill (Af) or eolian and dune deposits (Qe).

3.1.4.3 Radon

Radon is a radioactive gas that is found in certain geologic environments and is formed by the natural breakdown of radium, which is found in the earth’s crust. Radon is an invisible, odorless, inert gas that emits alpha particles, known to cause lung cancer. Radon levels are highest in basements (areas in close proximity to the soil) that are poorly ventilated. A radon survey was not included within the scope of this investigation. According to the “U.S. EPA Map of Radon Zones,” the County of Los Angeles is located within Zone 2, which has a predicted average indoor screening level of greater than or equal to 2.0 Picocuries per liter (pCi/L) and less than or equal to 4 pCi/L. EPA recommends remedial actions when radon levels are greater than 4.0 pCi/L.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 3-6 Section 3.0 | Records Review

3.1.5 BIOLOGICAL SETTING

The biotic community that exists on-site includes paved areas and ornamental landscaping.

3.1.6 DRAINAGE/HYDROLOGY

3.1.6.1 Drainage

Drainage of the subject site is accomplished by overland sheet flow into the roadway curb/gutters and catch basins in Artesia Boulevard and Aviation Boulevard, then through the City’s existing stormwater drainage system.

3.1.6.2 Flood Hazards

Flood Prone Area Maps published by the USGS show areas prone to 100-year floods overlaid on a topographical map. These maps are not considered the official Federal Emergency Management Agency (FEMA) flood maps; therefore, in cases where a property is located immediately adjacent to or within the flood prone boundary, a FEMA map should be obtained. According to the EDR Database search and the FEMA Flood Insurance Rate Maps (FIRM), the subject site is not located within a 100-year flood zone (refer to the Appendix B, Database Records Searches, and Appendix C).

3.1.6.3 Groundwater

According to the Second Quarter 2009 Groundwater Monitoring Report for the Former Shell Station (dated July 13, 2009) for 1650 Artesia Boulevard (adjoining the subject site to the south), the groundwater gradient is east/southeast.

3.1.6.4 Water Wells

The USGS Well Database and State Well Database were searched by EDR. According to the EDR Well search, no water wells are located within the boundaries of the subject site. Additionally, no water wells are located within 0.5-mile radius of the subject site (refer to the Appendix B).

3.2 STANDARD ENVIRONMENTAL RECORDS SOURCES

The governmental sources have been searched by EDR (at the request of Michael Baker) for sites within the subject site and within an approximate one-mile radius of the subject site boundaries.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 3-7 Section 3.0 | Records Review

This database is maintained by EDR and includes selected national collections of business directories that were available to EDR researchers. EDR’s review was limited to those categories of EDR US Hist Cleaners sources that might, in EDR’s opinion, include potential dry cleaner establishments. The categories reviewed included, but were not limited to dry cleaners, cleaners, laundry, laundromat, cleaning/laundry, wash and dry, etc. The Emissions Inventory Data (EMI) database includes toxics and criteria pollutant emissions data that EMI is collected by the Air Resources Board (ARB) and local air pollution agencies. The Facility Index System/Facility Registry System (FINDS) database contains both facility information and ‘pointers’ to other sources that contain more detail. EDR includes the following FINDS databases in their report: PCS (Permit Compliance System), AIRS (Aerometric Information Retrieval System), DOCKET (Enforcement Docket used to manage and track information on civil judicial enforcement FINDS cases for all environmental statutes), FURS (Federal Underground Injection Control), C-DOCKET (Criminal Docket System used to track criminal enforcement actions for all environmental statutes), FFIS (Federal Facilities Information System), STATE (State Environmental Laws and Statutes), and PADS (PCB Activity Data System). The HAZNET database extracts data from the copies of hazardous waste manifests received each year by the DTSC. The annual volume of manifests is typically 700,000-1,000,000 annually, representing approximately 350,000-500,000 shipments. Data from non-California manifests & HAZNET continuation sheets are not included at the present time. Data are from the manifests submitted without correction, and therefore many contain some invalid values for data elements such as generator ID, TSD ID, waste category, and disposal method. The source is the Department of Toxic Substance Control. The historic “Cortese” Hazardous Waste and Substances Sites List is a list of sites that are designated HIST CORTESE by the State Water Resources Control Board (SWRCB), the Integrated Waste Board, and the Department of Toxic Substances Control. The HIST UST database contains information on sites where historical underground storage tanks are HIST UST located. The Los Angeles County Site Mitigation List (LA Co. Site Mitigation) includes a listing of industrial sites LA Co. Site Mitigation that have had some sort of spill or complaint.

Database Description The Leaking Underground Storage Tank Incident Reports contain an inventory of reported leaking LUST underground storage tank incidents. The data comes from the State Water Resources Control Board Leaking Underground Storage Tank Information System. The Resource Conservation and Recovery Act (RCRA) – Large Quantity Generator (LQG) database contains selective information on sites which generate, transport, store, treat and/or dispose of RCRA-LQG hazardous waste as defined by RCRA. Large quantity generators generate over 1,000 kilograms (kg) of hazardous waste, or over 1 kg of acutely hazardous waste per month. The Resource Conservation and Recovery Act (RCRA) – Small Quantity Generator (SQG) database contains selective information on sites which generate, transport, store, treat, and/or dispose of RCRA-SQG hazardous waste as defined by RCRA. Small quantity generators generate less than 1,000 kilograms (kg) of hazardous waste, or over less than 1 kg of acutely hazardous waste per month. SQGs generate between 100 kg and 1,000 kg of hazardous waste per month. The Statewide Environmental Evaluation and Planning System, the SWEEPS UST database also SWEEPS UST maintains information on properties where an underground storage tank is located, however, this database is no longer updated. The Underground Storage Tank (UST) database contains registered USTs. USTs are regulated under UST Subtitle I of the Resource Conservation and Recovery Act (RCRA). The data comes from the State Water Resources Control Board’s Hazardous Substance Storage Container Database.

Adjacent Properties

The lists that were reviewed reported 10 regulatory sites adjacent to the subject site. These off- site regulatory properties are considered to have a low potential of affecting the subject site due to the distance, anticipated groundwater flow direction, and/or the status of the identified sites. Refer to Appendix B, for a listing of all properties noted.

3.2.3 UNMAPPED PROPERTIES

According to EDR’s ESA Report Desktop Reference, dated 1996, some reported sites are unmappable as exact locations remain undefined. Listings in publicly available records, which do not have adequate address information, are not generally considered practically reviewable. For the purposes of this Phase I ESA, practically reviewable is defined as information provided in a manner and in a form that yields information without the need for extraordinary analysis of irrelevant data. Although the location of these sites may be unknown, the site and detail information are often available through EDR.

Michael Baker’s review of Unmapped Properties consisted of a verification, based solely on the professional judgment of the Environmental Professional, that the subject site is not listed (i.e., referenced by name or street address) and a review to identify if any of the Unmapped Properties cause a likely potential to create an REC within the boundaries of the subject site. No listed Unmapped Properties are located within the boundaries of the subject site. Additionally, no unmapped properties are located within a one-mile radius of the subject site.

3.3 FILE RECORD REVIEWS

If the subject site or any of the adjoining properties are identified on one or more of the standard environmental record sources, pertinent regulatory files and/or records associated with the listing should be reviewed. The purpose of the regulatory file review is to obtain sufficient information to assist the environmental professional in determining if a REC, HREC, CREC, or a de minimis condition exists at the property in connection with the listing. If, in the environmental professional’s opinion, such a review is not warranted, the environmental professional must explain the justification for not conducting the regulatory file review.

Michael Baker requested records for all onsite and adjoining properties that have reported releases to soil and groundwater including the following:

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 3-13 Section 3.0 | Records Review

 1727 Artesia Boulevard (Former Mobil Service Station): This property is associated with the proposed partial ROW acquisition and is currently occupied by a Chase bank. However, this property was historically occupied by an Exxon Mobil Service Station. Files maintained by the Regional Water Quality Control Board (RWQCB) and City of Manhattan Beach Department of Public Works were reviewed.

 1700 Artesia Boulevard (Shell Service Station; Former Exxon Service Station): This property adjoins the subject site to the southeast (down-gradient) and is currently developed as a Shell Service Station. Files maintained by the RWQCB and Los Angeles County Fire Department Health Hazardous Materials Division (HHMD) were reviewed.

 1650 Artesia Boulevard (Former Shell Service Station): This property adjoins the subject site to the southwest (cross-gradient) and is currently occupied by an eight-unit condominium complex. However, this property was historically occupied by a Shell Service Station. Files maintained by the RWQCB were reviewed.

3.3.1 File Reviews Conducted

Michael Baker searched the Geotracker database for available files relative to the properties discussed above on July 7, 2017. Geotracker was developed pursuant to a mandate by the California State Legislature to investigate the feasibility of establishing a statewide Geographic Information System (GIS) for leaking underground fuel tank (LUFT) sites and is maintained by the State Water Resources Control Board. Michael Baker makes no claims as to the completeness or accuracy of Geotracker; our review of Geotracker’s findings can only be as current as their listings and may not represent all known or potential hazardous waste or contaminated sites.

Michael Baker requested files from the RWQCB, Department of Toxic Substances Control (DTSC), HHMD, and City of Manhattan Beach Department of Public Works. Files were obtained from the City of Manhattan Beach Public Works on March 10, 2016. Supplementary files were reviewed at the RWQCB on July 25, 2017. It is noted that Michael Baker requested files for 1751 Artesia Boulevard from the RWQCB, DTSC, LAFD, and City of Manhattan Beach Department of Public Works. However, agencies stated that no files are available for review. Michael Baker reviewed available files for the following reported properties:

1727 Artesia Boulevard (Historic Mobil Service Station): This property (adjoining the subject site to the west) is currently occupied by a Chase Bank and was historically occupied by an Exxon Mobil Service Station. This Exxon Mobil Service Station reported a release of hydrocarbons to the soil. In 1988, the first generation of underground storage tanks (USTs) were removed from

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 3-14 Section 3.0 | Records Review

the northwestern portion of the site and replaced with the second generation of USTs in the northeastern portion of the site. Groundwater monitoring was performed from 1987 to 1998. Results of the groundwater monitoring indicated that dissolved-phase benzene was localized to the western portion of the site, and concentrations showed a declining trend after the completion of remedial activities in 1996. The Los Angeles Regional Water Quality Control Board granted the site closure in its letter dated September 4, 1998, and all wells were abandoned. In March 2003, the service station was abandoned. In May 2005, three additional soil borings were drilled to delineate the vertical extent of residual adsorbed-phase hydrocarbons detected beneath the former fueling facilities. On March 8, 2007, a secondary excavation was conducted to 9 to 19 feet below ground surface (bgs) to remove hydrocarbon-containing soil and 9.23 tons of hydrocarbon- containing soil was transported off-site. Based upon these site conditions, the Los Angeles Regional Water Quality Control Board granted the site closure in its letter dated July 10, 2007.

1700 Artesia Boulevard (Shell Service Station; Former Exxon Service Station):

Former Exxon Service Station

This property adjoining the subject site to the southeast was formerly occupied by an Exxon Service Station and consisted of three USTs containing motor vehicle fuel with associated product piping, dispenser islands, vent lines, and a station building. During excavation activities to remove the former USTs, soil sampling took place to delineate the vertical and lateral extent of hydrocarbons in the soil beneath the site. Based on the analytical results of soil sampling at the site, it was determined that hydrocarbons in the soil beneath the property were localized in two areas; in the area surrounding the former gasoline USTs in the southwestern portion of the property and at the eastern end of the northern dispenser islands. In addition, petroleum hydrocarbons were confirmed to exist within on-site soils to the west of the dispenser islands in the eastern portion of the property. Depth to groundwater at the property was estimated to be at 97 feet bgs and there was no significant potential for hydrocarbon impact to groundwater beneath the site from the former USTs or dispenser islands.

In October of 1994, a sol vapor extraction (SVE) test was conducted to determine the feasibility of vapor extraction as a remediation option. The results of the study indicated that vapor extraction was an effective remediation method for removing volatile hydrocarbons from the soil beneath the site and a remediation action plan was prepared. No information to determine if hydrocarbon concentrations were removed from on-site soils to asymptotic levels by the SVE system was available. Based on the information available the Los Angeles Regional Water Quality Control Board granted the site closure on December 11, 1996.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 3-15 Section 3.0 | Records Review

Shell Service Station This property is currently occupied by a Shell Service Station and consists of three 10,000 gallon USTs containing gasoline with associated product piping, eight dispenser islands, an Valvoline auto service building, a food mart building, and a car wash building. Excavation activities to replace product line piping, soil sampling was performed at the site on January 6, and January 7, 2010. A total of eighteen soil samples from approximately 3.5 feet below the former product and UST vent piping. Two stockpile samples were also collected. All soil samples were analyzed for total petroleum hydrocarbons as gasoline (TPHg), and benzene, toluene, ethylbenzene, and xylenes (BTEX), ethanol, and fuel oxygenates (di-isopropyl ether [DIPE], ethyl tertiary butyl ether [ETBE], methyl tertiary butyl ether [MTBE], tertiary amyl methyl ether [TAME], and tertiary butyl alcohol [TBA]). Laboratory results indicated maximum detected concentration of TPHg, ethylbenzene, and xylenes were 0.4J milligrams per kilogram (mg/kg) 0.001J mg/kg, and 0.003 mg/kg, respectively. Benzene, toluene, ethanol and fuel oxygenates were not detected at or above their respective reporting limits in either soil sample collected in January 2010. Based on the information available, the Los Angeles Regional Water Quality Control Board determined that residual concentrations of fuel constituents pose a low threat to human health, and soil and groundwater quality beneath the site. The Regional Board issued a no case letter for the site on August 5, 2015.

1650 Artesia Boulevard (Former Shell Service Station): This property (adjoining the subject site to the southwest) is occupied as an eight-unit condominium complex and was historically occupied by a Shell Service Station. This Shell Service Station reported a release of hydrocarbon to groundwater. In February 1999, three 10,000-gallon USTs, one 550-gallon waste oil UST, five product dispensers, three hoists, one clarifier, and all associated product piping were removed from the site. Following tank removal, TPH-g, BTEX compounds, and MTBE were detected in the soil collected in the vicinity of the fuel USTs. Additionally, TPH-g, BTEX compounds, and fuel oxygenates were detected in groundwater samples collected and analyzed in August 1999, October 2000, and July 2002. Routine groundwater monitoring activities took place from December 2000 to August 2008. According to the Closure Request/Remedial Action Plan, dated April 22, 2010, the potential source of the petroleum hydrocarbon impact has been removed via removal of the USTs, dispensers, hoists, the clarifier, and all subgrade piping, a review of groundwater data obtained since September 2008 indicates concentrations of TPH-g, BTEX compounds, and fuel oxygenates are stable, and bioremediation is occurring in groundwater. Based on this information, the Los Angeles Regional Water Quality Control Board granted the site closure in its closure letter dated October 20, 2010.

3.4 HISTORICAL USE INFORMATION ON THE SUBJECT SITE AND ADJOINING PROPERTIES

The objective of consulting historical sources is to develop a history of the previous uses of the property and surrounding area, in order to help identify the likelihood of past uses having led to RECs in connection with the property. The Environmental Professional shall exercise professional judgment and consider the possible releases that might have occurred at a property in light of the historical uses and, in concert with other relevant information gathered as part of the Phase I ESA process, use this information to assist in identifying RECs (discussed in Section 6.0, Evaluation, of this Phase I ESA).

The standard sources identified by ASTM E 1527-13 include aerial photographs, fire insurance maps, property tax files, recorded land title records (a chain-of-title), historical USGS topographic maps, local street directories, building department records, zoning/land use records, prior assessments, and other historical sources (i.e., any source or sources, other than those listed, that are credible to a reasonable person and that identify past uses of the property). The focus is on usage rather than ownership, which is why a chain-of-title is not sufficient by itself.

3.4.1 METHODOLOGY AND LIMITING CONDITIONS

3.4.1.1 Methodology

Data failure (a subset of a data gap) occurs when all of the standard historical sources that are reasonably ascertainable and likely to be useful have been reviewed and yet the historical source review objectives have not been met.

USES OF THE PROPERTY

Per ASTM E 1527-13 Standard Practice, historical uses “shall be identified from the present, back to the property’s obvious first development use including (agricultural and fill activities), or back to 1940, whichever is earlier.” This task requires reviewing only as many of the standard historical sources as are necessary and both reasonably ascertainable and likely to be useful.

Historical information for the subject site was obtained back to 1896, at which time the subject site consisted of transportation uses. Sources reviewed have been cited throughout this section and are referenced in Section 7.0, References, of this Phase I ESA.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 3-17 Section 3.0 | Records Review

INTERVALS

Review of standard historical sources at less than approximately five year intervals is not required by ASTM E 1527-13 Standard Practice. If the specific use of the property appears unchanged over a period longer than five years, then it is not required by ASTM E 1527-13 Standard Practice to research the use during that period.

Michael Baker did not encounter data failure with regard to source intervals during the course of this Phase I ESA.

USES OF PROPERTIES IN SURROUNDING AREA

Uses in the area surrounding the property shall be identified in the Phase I ESA, but this task is only required to the extent that this information is revealed in the course of researching the property itself. If the environmental professional uses sources that include the surrounding area, surrounding uses should be identified to a distance determined at the discretion of the environmental professional. Factors to consider in making this determination include, but are not limited to:

 The extent to which information is reasonably ascertainable;  The time and cost involved in reviewing surrounding uses;  The extent to which information is useful, accurate, and complete in light of the purpose of the records review;  The likelihood of the information being significant to RECs in connection with the property;  The extent to which potential concerns are obvious;  Known hydrogeologic/geologic conditions that may indicate a high probability of hazardous substances or petroleum products migration to the property;  How recently local development has taken place;  Information obtained from interviews and other sources; and  Local good commercial and customary practice.

Surrounding land uses have been noted throughout the Phase I ESA, as applicable, and are referenced accordingly.

3.4.1.2 Limiting Conditions

Michael Baker did not encounter any other conditions that limited the historical use review during the course of this Phase I ESA.

3.4.2 STANDARD HISTORICAL SOURCES

3.4.2.1 Historical Uses Summary

Based upon the evaluation of the documented land use as demonstrated in the resources reviewed as part of this Phase I ESA, the subject site appears to historically been used as transportations uses (roadway) along Artesia Boulevard and Aviation Boulevard within the City of Manhattan Beach. The on-site property located at 1727 Artesia Boulevard appears to have been historically vacant land, developed as commercial uses (service station) by 1970, and reconfigured by 1989 and 2007.

Between the years of 1896 and 1924 transportation uses (Gould Lane) appear to have been constructed on-site. By 1928 the surrounding area has been developed with residential and agricultural land uses. By 1934, Gould Lane (Artesia Boulevard) has been improved and by 1938 both Artesia Boulevard and Aviation Boulevard were widened. By 1941 both roadways are indicated as primary highways throughout the City of Manhattan Beach. Between 1952 and 1963, the intersection of Artesia Boulevard and Aviation Boulevard was widened and Aviation Boulevard has been extended to the north.

Between 1963 and 1970, the subject site appears to be developed with an automobile service station. By 1977, Artesia Boulevard was widened and the subject site received additional improvements including the construction of sidewalks adjoining the intersection of Artesia Boulevard and Aviation Boulevard, and a new lane configuration similar to the present day condition. The subject site was redeveloped by 1989 and listed as a commercial use (Johnson Mobil) by 2001. Between 2007 and 2009, the on-site structure appears to have been reconfigured a second time, similar to present day conditions.

Development in the general vicinity of the subject site appears to have begun in the 1920’s. The properties located along Mathews Avenue were developed with residential uses by 1957. By 1977, a residential use appears to be adjoining the subject site to the north (1736 Mathews Avenue). The property located at 1751 Artesia Boulevard (to the east) was developed with a gasoline service station from the 1960’s to the 1980’s before being redeveloped to a commercial building. The property located at 1700 Artesia Boulevard was developed with a gasoline service

SECTION 4.0 SITE RECONNAISSANCE

According to the ASTM E 1527-13 Standard Practice, the objective of the site reconnaissance is to obtain information indicating the likelihood of identifying RECs in connection with the subject site.

4.1 METHODOLOGY AND LIMITING CONDITIONS

4.1.1 METHODOLOGY

Michael Baker performed a visual observation of readily accessible areas of the subject site and immediately adjoining properties on July 12, 2017. At this time, the subject site was visually inspected. Refer to Exhibit 5, On-Site Photographs, and Exhibit 6, Off-Site Photographs, for photographic documentation conducted during the site visit. The subject site was viewed from all public thoroughfares. If roads or paths with no apparent outlet are observed on the subject site, the use of the road or path was identified to determine whether it was likely to have been used as an avenue for disposal of hazardous substances or petroleum products.

4.1.2 LIMITING CONDITIONS

lanes (two lanes in each direction) with an additional southbound center left-turn lane. The subject site also encompasses the westbound through lane of Artesia Boulevard. Associated curb and gutter, and a concrete sidewalk are located within the boundaries of the subject site. The proposed ROW acquisition of a portion of 1727 Artesia Boulevard would be required. No on-site structures are located within the boundaries of the subject site. Areas of acquisition consist of vacant land (paved driveway area and ornamental landscaping) associated with the off-site Chase Bank structure.

4.2.3 DESCRIPTION OF PAST USES OF THE SUBJECT SITE

Based on review of USGS Topographical Quadrangle maps, aerial photographs, and the city directory search, past uses of the subject site are reported to consist of transportation and commercial land uses (retail/restaurants and a former gasoline service station). No evidence to suggest the presence of other past uses was noted during the July 12, 2017 site visit.

4.2.4 HAZARDOUS SUBSTANCES AND PETROLEUM PRODUCTS

Michael Baker did not observe hazardous substances or petroleum products associated with the subject site.

4.2.5 CHEMICAL STORAGE TANKS (ASTS AND USTS)

Michael Baker did not observe chemical storage tanks (aboveground storage tanks [ASTs] and USTs) on-site during the site visit.

4.2.6 SPILLS

No visual or physical evidence of stained catch basins, drip pads, sumps, or stained soils was observed during the July 12, 2017, site inspection.

4.2.7 SOLID WASTE DISPOSAL

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 4-4 Section 4.0 | Site Reconnaissance

4.2.8 UTILITIES

Typical roadside utilities (e.g., water-related utilities, including stormwater drainage and irrigation utilities, and electric utilities) were noted during the site inspection. No staining or leakage was noted with respect to on-site utilities.

4.2.8.1 Polychlorinated Biphenyls (PCBs)

No power poles or other electrical equipment were observed within the boundaries of the subject site.

4.2.8.2 Wells

No water wells were observed within the boundaries of the subject site during the July 12, 2017 site visit.

4.2.8.3 Potable Water Supply

No evidence of a potable water supply was noted during the site visit. However, the surrounding area appeared to be connected to the City’s local water system.

4.2.8.4 Sewage Disposal System

Evidence of a sewage disposal system (a sewer manhole along Aviation Boulevard) was noted on-site during the July 12, 2017 site visit. No evidence of other sewage disposal systems (including septic systems) was observed.

4.2.8.5 Heating/Cooling

No structures are located within the subject site; therefore, Michael Baker did not observe any heating or cooling systems during the site visit.

4.2.9 DRAINS AND SUMPS

Storm drain systems (curb and gutter) were noted along Artesia Boulevard and Aviation Boulevard. A catch basin was observed along Artesia Boulevard within the vicinity of the subject site.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 4-5 Section 4.0 | Site Reconnaissance

4.2.10 PITS, PONDS, LAGOONS

No pits, ponds, or lagoons were noted during the July 12, 2017 site visit.

4.2.11 LEAD-BASED PAINTS

Lead-Based Paints (LBPs) were commonly used in traffic striping materials before the discontinued use of lead chromate pigment in traffic striping/marking materials and hot-melt Thermoplastic stripe materials (discontinued in 1996 and 2004, respectively). Traffic striping was observed along Artesia Boulevard and Aviation Boulevard during the July 12, 2017 site visit. Thus, LBPs may be present within traffic striping. However, traffic striping was noted to be in good condition.

4.2.12 AERIALLY DEPOSITED LEAD

ADL refers to lead deposited on highway shoulders from past leaded fuel vehicle emissions. According to the Caltrans ADL webpage (Caltrans 2014), although leaded fuel has been prohibited in California since the 1980’s, ADL may still be present in soils adjacent to highways in use prior to that time. Thus, there is potential for lead contamination to exist within soils along the subject site due to ADL. However, areas of the subject site are paved; no areas of bare soil are present other than a few small areas of landscape planters. Thus, lead contamination within on- site soils is not anticipated.

4.2.13 ASBESTOS-CONTAINING MATERIAL

Asbestos is a strong, incombustible, and corrosion resistant material, which was used in many commercial products since prior to the 1940s and up until the early 1970s. If inhaled, asbestos fibers can result in serious health problems. Asbestos containing materials (ACMs) are building materials containing more than one percent asbestos (some state and regional regulators impose a 0.1 percent threshold). No habitable structures are located on-site; therefore, the potential for ACMs to be found on-site as a result of building materials is unlikely.

4.3 OFF-SITE OBSERVATIONS

An adjoining property is considered any real property or properties that the border of which is contiguous or partially contiguous with that of the subject site, or that would be contiguous or partially contiguous with that of the subject site but for a street, road, or other public thoroughfare separating them. An adjacent property is any real property located off-site, which is not

adjoining. Visual observations of the publicly accessible portions of adjoining properties were conducted on July 12, 2017 as part of this Phase I ESA and are described below.

4.3.1 DESCRIPTION OF CURRENT AND PAST USES OF THE SURROUNDING AREA

Current uses surrounding the subject site primarily consist of residential, transportation, and commercial land uses. Past uses consisted of vacant land, residential, commercial, and transportation land uses. No evidence to suggest past uses was observed during the July 12, 2017 site inspection.

4.3.2 DESCRIPTION OF CURRENT USES AND STRUCTURES AT ADJOINING PROPERTIES

Adjoining uses observed included commercial, residential, and transportation (Aviation Boulevard) uses to the north; commercial and transportation (Artesia Boulevard) uses to the east; commercial, residential, and transportation (Aviation Boulevard) uses to the south; and commercial and transportation (Artesia Boulevard) uses to the west. Adjoining structures include a one story commercial structure (Chase Bank) to the west; a commercial strip mall to the east; a Shell Service Station consisting of a food mart structure, Valvoline auto service structure, drive-thru car wash structure, and eight dispenser islands to the southeast; and a two-story residential apartment structure (Aviation Villas) to the southwest. No unusual or suspicious materials handling or storage practices were observed with respect to adjoining properties.

4.3.3 DESCRIPTION OF PAST USES AND STRUCTURES AT ADJOINING PROPERTIES

Based on available documentation obtained, off-site adjoining uses appear to have historically consisted of residential, commercial, transportation, and vacant land uses. Residential uses adjoining the subject site to the north were developed from the 1950s to 1970s. A former Chevron Service Station was noted at 1751 Artesia Boulevard from 1960s to 1970s adjoining the subject site to the east. Beginning in the 1980s, this site was redeveloped as a strip mall with associated surface parking uses similar to the present day configuration. A former Shell Service Station was noted at 1725 Artesia Boulevard (historically 1650 Artesia Boulevard) from the 1970s to 1990s adjoining the subject site to the southwest. Beginning in the 2000s, the site was redeveloped as residential uses similar to the present day configuration. Since the 1970s a former service station was noted at 1700 Artesia Boulevard adjoining the subject site to the southeast. The site was redeveloped by 2002 to include an additional commercial structure (EZ Lube) similar to the

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 4-7 Section 4.0 | Site Reconnaissance

present day configuration. By 1989, a commercial structure adjoining the subject site to the west was developed. No evidence to suggest other past uses was observed during the July 12, 2017, site visit.

4.3.4 OBSERVATIONS OF OFF-SITE PROPERTIES

4.3.4.1 Utilities

Typical roadside utilities (e.g., stormwater drainage, sewer, irrigation, and electrical utilities including overhead power lines, pad-mounted transformer and pole-mounted electrical transformers) were noted during the site inspection. No staining or leakage was observed with respect to off-site utilities.

4.3.4.2 Chemical Storage Tanks

Michael Baker observed fuel islands at the Shell Service Station adjoining the subject site to the southeast during the July 12, 2017 site visit.

4.3.4.3 Hazardous Materials

During a preliminary observation of surrounding properties on July 12, 2017, no visible physical evidence was observed to suggest that a surface release of petroleum-based material has recently occurred. However, the Shell Service Station adjoining the subject site to the southeast is anticipated to handle hazardous materials. No other unusual or suspicious materials handling or storage practices were observed with respect to adjacent properties.

SECTION 5.0 INTERVIEWS

The ASTM E 1527-13 Standard Practice indicates that the objective of interviews is to obtain information indicating RECs in connection with the subject site. Interviews with past and present owners, operators, and occupants of the property consist of questions to be asked in the manner and of persons as described in the ASTM E 1527-13 Standard Practice. The content of questions to be asked shall attempt to obtain information about uses and conditions observed during the site reconnaissance as well as the documentation review. The content of questions to be asked of State and/or local government officials shall be decided in the discretion of the environmental professional(s) conducting the Phase I ESA, provided that the questions shall generally be directed towards identifying RECs in connection with the subject site.

5.1 PROPERTY OWNER

Due to the nature of the project (proposed roadway improvements), current and past property owners were not readily available for interview.

5.2 KEY SITE MANAGER/OPERATOR

A key site manager, identified by the property owner, is a person with good knowledge of the uses and physical characteristics of the property. Often the Key Site Manager is the property manager, the chief physical plant supervisor, or head maintenance person. If the user is the current property owner, the user has an obligation to identify a key site manager, even if it is the user himself or herself.

The City of Manhattan Beach has identified the Project Engineer, Mr. Brian Anderson, P.E., with Michael Baker International, as the Key Site Manager for the purposes of this analysis. Mr. Anderson has provided Michael Baker with information pertaining to the subject site throughout this Phase I ESA, which has been referenced accordingly.

5.3 OCCUPANTS

No occupants are associated with the subject site, as the site consists of transportation uses. In addition, no habitable structures are located within the proposed ROW acquisition located at 1727

SECTION 6.0 EVALUATION

Michael Baker has performed a Phase I ESA in general conformance with the scope of services and limitations of ASTM E 1527-13 Standard Practice of the Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project, City of Manhattan Beach, California, also known as the subject site within this Phase I ESA. Any exceptions to, or deletions from, this practice are described in the Section 1.0, Introduction, of this report. This Phase I ESA has revealed the following in connection with the subject site.

6.1 FINDINGS AND OPINIONS

The following findings and opinions are based upon review of reasonable ascertainable referenced material available to Michael Baker during the preparation of this Phase I ESA, which included a review of historical aerial photographs, historical topographic maps, regulatory databases, and other documentation, as well as interviews and site reconnaissance.

6.1.1 CURRENT ON-SITE USES

The subject site currently consists of transportation and commercial land uses. Within the vicinity of the subject site, Aviation Boulevard contains four lanes (two lanes in each direction) with an additional southbound center left-turn lane. The subject site also encompasses the westbound through lane of Artesia Boulevard. Associated curb and gutter, and a concrete sidewalk are located within the boundaries of the subject site. Areas of proposed ROW acquisition consist of vacant land (paved driveway area and ornamental landscaping) associated with the Chase Bank located at 1727 Artesia Boulevard. No habitable structures are located within the project site.

6.1.1.1 Lead Based Paints (Traffic Striping Material)

LBPs were commonly used in traffic striping materials before the discontinued use of lead chromate pigment in traffic striping/marking materials and hot-melt thermoplastic stripe materials (discontinued in 1996 and 2004, respectively). Michael Baker observed traffic striping along Artesia Boulevard and Aviation Boulevard during the July 12, 2017 site visit. Thus, LBPs may be present within traffic striping.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 6-1 Section 6.0 | Evaluation

As the on-site striping materials is currently contained, and no visible evidence to suggest the release of LBPs into the environment was observed, it is Michael Baker’s opinion that the likely presence of LBPs in traffic striping materials is not a REC at the time of this Phase I ESA.

6.1.1.2 Current Commercial Uses

The Chase Bank located at 1727 Artesia Boulevard is proposed for partial ROW acquisition. Areas of proposed ROW acquisition consist of vacant land (paved driveway area and ornamental landscaping). No contamination to soil or groundwater was reported in association with the current Chase Bank facility. Further, no indication of a release was observed during the site visit on July 12, 2017. As this facility has not reported releases of hazardous materials to the soils, surface water, or groundwater, it is the opinion of Michael Baker that no REC has resulted on-site as a result of this current use.

6.1.2 PAST ON-SITE USES

Based upon the evaluation of the documented land use (as demonstrated in the resources reviewed as part of this Phase I ESA), the subject site appears to have consisted of transportations uses (roadway) along Artesia Boulevard and Aviation Boulevard within the City of Manhattan Beach. Past on-site uses associated with ROW acquisition include a former gasoline service station. The following is a discussion of findings made in association with past on-site uses.

6.1.2.1 1727 Artesia Boulevard (Former Mobil Gasoline Service Station)

This property is associated with the proposed partial ROW acquisition (currently Chase Bank) and was historically occupied by an Exxon Mobil Service Station. This property is reported in the EDR US Hist Auto, RCRA-LQG, LUST, SWEEPS UST, CA FID UST, HIST CORTESE, HIST UST, CHMIRS, and UST databases. This property consisted of a gasoline service station from the 1970’s to the 2000’s and reported a release of gasoline to groundwater.

In 1988, the first generation of USTs was removed from the northwestern portion of the property and replaced with a second generation of USTs in the northeastern portion of the subject site. During this time, the structures were reconfigured. Results of compliance sampling indicated a release hydrocarbons to on-site soils and groundwater beneath the western portion of the property. Remediation activities took place and were completed in 1996. Groundwater monitoring was performed from 1987 to 1988. Results of the groundwater monitoring showed a declining trend of hydrocarbon concentration since completion of remediation activities. The RWQCB granted the initial site closure on September 4, 1998.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 6-2 Section 6.0 | Evaluation

A second release of petroleum hydrocarbons to soil was reported. This case was closed by the RWQCB on July 10, 2007. By the 2000s, the gasoline service station was redeveloped into a commercial building. However, proposed excavation activities would only occur within the top 20 feet; groundwater is not anticipated to be encountered during project construction.

Additionally, the users of this Phase I ESA provided Michael Baker with a Title/Grant Deed, dated December 8, 2003. The Grant Deed indicates land use restrictions (such as residential, hospital, child care, etc., not permitted at the property) and residual soil contamination from the former gasoline service station.

It is the opinion of Michael Baker that a Phase II/Site Characterization Specialist conduct sampling during the project design phase. Since this past release has achieved case closure by the RWQCB with land use restrictions, it is the opinion of Michael Baker that a CREC has resulted.

6.1.2.2 Aerially Deposited Lead

ADL refers to lead deposited on highway shoulders from past leaded fuel vehicle emissions. According to the Caltrans ADL webpage (Caltrans 2014), although leaded fuel was has been prohibited in California since the 1980’s, ADL may still be present in soils adjacent to highways in use prior to that time.

According to historical aerial photographs, and topographic maps, the subject site appears to have consisted of transportation uses since 1924. However, the on-site roadways are paved and the areas adjoining the roadways are entirely built out. Further, the proposed ROW acquisition area is paved, or has landscaped planters, and is highly disturbed. Thus, the potential for lead contamination to exist within soils along on-site roadways due to ADL is unlikely. It is the opinion of Michael Baker that ADL has not resulted in a REC on-site and no further recommendation is necessary.

6.1.3 CURRENT ADJOINING PROPERTIES

Adjoining uses currently consist of transportation, commercial, and residential uses to the north; commercial uses to the east; transportation and commercial uses to the south; and transportation and commercial uses to the west of the subject site. The following is a discussion of findings made in association with current adjoining properties.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 6-3 Section 6.0 | Evaluation

6.1.3.1 Commercial and Residential Uses Not Anticipated to Handle, Store, or Transport Hazardous Materials

The following sites are adjoining the subject site and are not anticipated to currently handle, store, or transport hazardous materials:

 1721 Artesia Boulevard (commercial uses);  1725 Artesia Boulevard (Aviation Villas Apartment Homes); And  1751 Artesia Boulevard (Strip Mall).

These current facilities do not appear to involve hazardous materials. No known corrective action, restoration, or remediation has been planned, is currently taking place, or has been completed on the adjoining properties. The adjoining properties have not been under investigation for violation of any environmental laws, regulations, or standards, as identified in the databases reported in EDR (refer to Appendix B). Based on the information reviewed as part of this Phase I ESA, it is the opinion of Michael Baker that no REC has resulted on-site as a result these properties.

6.1.3.2 Commercial Uses That Have Reported Releases

The following adjoining uses have reported releases and are located in proximity to the subject site:

 1700 Artesia Boulevard (Shell Service Station)

This property adjoins the subject site to the southeast and is currently occupied by a Shell Service Station. This property consists of three 10,000 gallon underground storage tanks (USTs) containing gasoline with associated product piping, eight dispenser islands, a Valvoline auto service building, a food mart building, and a drive-thru car wash building.

This current use has reported a release to soil at the time of product line piping replacement in 2010. During excavation activities to replace product line piping, soil sampling was performed at the site on January 6, and January 7, 2010 and the soil samples were analyzed for petroleum hydrocarbons. Gasoline, ethylbenzene and xylenes were detected near the dispenser islands adjoining the subject site to the east. Concentration levels of gasoline and other petroleum hydrocarbons were considered below action levels. Based on the files reviewed, the RWQCB determined that residual concentrations of fuel constituents posed a low threat to human health, and to soil and groundwater

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 6-4 Section 6.0 | Evaluation

quality beneath the site. The RWQCB issued a no case letter for the site on August 5, 2015. Based on the available files reviewed, and considering this property is greater than 100 feet down gradient from the subject site, it is the opinion of Michael Baker that this adjoining property has not resulted in a REC at the subject site.

6.1.4 PAST ADJOINING USES

Based on the available documentation obtained, off-site adjoining uses appear to have historically consisted of residential, commercial, transportation, and vacant land uses. Adjoining properties of concern include past gasoline service stations and dry cleaners, further discussed as follows:

6.1.4.1 1650 Artesia Boulevard (Former Shell Gasoline Service Station)

This property is located at the southwest corner of Artesia Boulevard and Aviation Boulevard adjoining the subject site to the southwest. This property consisted of a gasoline service station from the 1960’s to the 1990’s and is reported in the RCRA-SQG, LUST, and SWEEPS UST databases. This property reported a release of gasoline to groundwater.

This Shell Service Station reported a release of hydrocarbon to groundwater. Following tank removal activities, TPH-g, BTEX compounds, and MTBE were detected in the soil collected in the vicinity of the fuel USTs. Additionally, TPH-g, BTEX compounds, and fuel oxygenates were detected in groundwater samples collected and analyzed in August 1999, October 2000, and July 2002. Routine groundwater monitoring activities took place from December 2000 to August 2008. According to the Closure Request/Remedial Action Plan, dated April 22, 2010, the potential source of the petroleum hydrocarbon impact had been removed and a review of groundwater data obtained since September 2008 indicated concentrations of TPH-g, BTEX compounds, and fuel oxygenates are stable, and bioremediation is occurring in groundwater. Based on this information, the RWQCB granted the site closure in its closure letter dated October 20, 2010.

Based on files reviewed, monitoring wells nearest the subject site reported elevated levels of TPH- g, Toluene, MTBE, and DIPE. By the 2000’s, the gasoline service station was redeveloped into the existing residential building. Proposed excavation is not anticipated to exceed 20 feet bgs. Based on files reviewed as part of this Phase I ESA, groundwater is approximately 72.80 to 73.70 feet bgs at this site (although more recent files reviewed for neighboring properties show groundwater at 97 feet bgs). Thus, contaminated groundwater underneath the subject site as a result of past adjoining uses at 1650 Artesia Boulevard is likely. However, as groundwater is not anticipated to be encountered, it is the opinion of Michael Baker that this adjoining release has resulted in a de minimis condition at the subject site and no REC has resulted.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | 6-5 Section 6.0 | Evaluation

6.1.4.2 1751 Artesia Boulevard (Former Chevron Gasoline Service Station, Arlo’s Plaza Cleaners)

This property is located at the northeast corner of Artesia Boulevard and Aviation Boulevard adjoining the subject site to the east. This property consisted of a gasoline service station from the 1960’s to the 1970’s before being redeveloped into a commercial strip mall in the 1980’s, similar to the existing structure at this adjoining property. A drycleaners facility was reported at this property from 2001 to 2012. This facility is situated less than 100 feet down-gradient from the subject site and could have impacted groundwater as a result of past adjoining uses at 1751 Artesia Boulevard. Proposed excavation is not anticipated to exceed 20 feet bgs. Based on files reviewed as part of this Phase I ESA, groundwater is approximately 72.80 to 73.70 feet bgs at this site (although more recent files reviewed for neighboring properties show groundwater at 97 feet bgs). However, as groundwater is not anticipated to be encountered, it is the opinion of Michael Baker that this adjoining release has resulted in a de minimis condition at the subject site and no REC has resulted.

6.1.4.3 1700 Artesia Boulevard (Former Exxon Service Station)

This property is located at the southeast corner of Artesia Boulevard and Aviation Boulevard adjoining the subject site to the southeast. This property (currently a Shell Service Station) was formerly occupied by an Exxon Service Station and consisted of three underground storage tanks (USTs) located in the southwest portion of the subject site containing motor vehicle fuel with associated product piping, dispenser islands, vent lines, and a station building.

During excavation activities to remove the former USTs, soil sampling took place to delineate the vertical and lateral extent of hydrocarbons in the soil beneath the site. Based on the analytical results of soil sampling at the site, it was determined that hydrocarbons in the soil beneath the site were localized in two areas; in the area surrounding the former gasoline USTs in the southwestern portion of the site and at the eastern end of the northern dispenser islands. In addition, petroleum hydrocarbons were confirmed to exist within on-site soils to the west of the dispenser islands in the eastern portion of the subject site. Depth to groundwater at the site was estimated to be at 97 feet bgs and there was no significant potential for hydrocarbon impact to groundwater beneath the site from the former USTs or dispenser islands.

In October of 1994, a soil vapor extraction (SVE) test was conducted to determine the feasibility of vapor extraction as a remediation option. The results of the study indicated that vapor extraction was an effective remediation method for removing volatile hydrocarbons from the soil beneath the site and a remediation action plan was prepared. No information to determine if

hydrocarbon concentrations were removed from on-site soils to asymptotic levels by the SVE system was available. The RWQCB granted the site closure on December 11, 1996.

Based on the available files reviewed, and considering this property is greater than 100 feet down- gradient from the subject site, it is the opinion of Michael Baker that this adjoining property has not resulted in a REC at the subject site.

6.1.5 CURRENT AND PAST ADJACENT USES

Current and past adjacent uses consist of vacant undeveloped land, commercial, residential, agricultural, and transportation uses. Multiple adjacent properties were listed in multiple regulatory databases involving hazardous materials. However, based on the information reviewed as part of this Phase I ESA, no reported adjacent regulatory properties have been identified that also present a potential concern to groundwater underlying the subject site. Reported adjacent regulatory properties are considered to have a low potential of affecting the subject site for one or more of the following reasons: distance from the subject site, direction of anticipated groundwater flow, site status, and/or no contamination has been reported. Thus, it is the opinion of Michael Baker that no REC has resulted from adjacent regulatory properties.

6.1.7 DATA GAPS

A data gap is a lack of or inability to obtain information required by the ASTM E 1527-13 Standard Practice despite good faith efforts by the Environmental Professional to gather such information. Data gaps may result from incompleteness in any of the activities required by this practice, including but not limited to site reconnaissance (for example, an inability to conduct the site visit) and interviews (for example, an inability to interview the key site manager, regulatory officials, etc.). A data gap by itself is not inherently significant. For example, if a property’s historical use in not identified back to 1940 because of data failure, but the earliest source shows that the property was undeveloped, this data gap by itself would not be significant. A data gap is only significant if other information and/or professional experience raises reasonable concerns involving the data gap. For example, if a building on the property is inaccessible during the site visit, and the Environmental Professional’s experience indicates that such a building often involves activity that leads to an REC, the inability to inspect the building would be a significant data gap warranting comment.

No significant data gaps were noted during the course of the Phase I ESA. Refer to Section 6.3, Limiting Conditions/Deviations, below.

APPENDICES

APPENDIX A: ASTM TERMINOLOGY

TERMINOLOGY

The following definitions and descriptions of terms are from the ASTM E1527-13 Standard Practice for Environmental Site Assessments: Phase I Environmental Site Assessment Process.

Abandoned property – property that can be presumed to be deserted, or an intent to relinquish possession or control can be inferred from the general disrepair or lack of activity thereon such that a reasonable person could believe that there was an intent on the part of the current owner to surrender rights to the property.

Activity and use limitations – legal or physical restrictions or limitations on the use of, or access to, a site or facility: (1) to reduce or eliminate potential exposure to hazardous substances or petroleum products in the soil, soil vapor, groundwater, and/or surface water on the property, or (2) to prevent activities that could interfere with the effectiveness of a response action, in order to ensure maintenance of a condition of no significant risk to public health or the environment. These legal or physical restrictions, which may include institutional and/or engineering controls, are intended to prevent adverse impacts to individuals or populations that may be exposed to hazardous substances and petroleum products in the soil, soil vapor, groundwater, and/or surface water on the property. See Note 1.

NOTE 1 — the term AUL is taken from Guide E2091 to include both legal (that is, institutional) and physical (that is, engineering) controls within its scope. Other agencies, organizations, and jurisdictions may define or utilize these terms differently (for example, EPA and California do not include physical controls within their definitions of “institutional controls.” Department of Defense and International County/City Management Association use “Land Use Controls.” The term ‘land use restrictions” is used but not defined in the Brownfields Amendments).

Actual knowledge – the knowledge actually possessed by an individual who is a real person, rather than an entity. Actual knowledge is to be distinguished from constructive knowledge that is knowledge imputed to an individual or entity.

Adjoining properties – any real property or properties the border of which is contiguous or partially contiguous with that of the property, or that would be contiguous or partially contiguous with that of the property but for a street, road, or other public thoroughfare separating them.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | A-1 Appendix A | ASTM Terminology

Aerial photographs – photographs taken from an aerial platform with sufficient resolution to allow identification of development and activities of areas encompassing the property. Aerial photographs are often available from government agencies or private collections unique to a local area.

All appropriate inquiry – that inquiry constituting “all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice” as defined in CERCLA. 42 U.S.C. §9601(35)(B), that will qualify a party to a commercial real estate transaction for one of threshold criteria for satisfying the LLPs to CERCLA liability (42 U.S.C. §9601(35)(A) & (B), §9607(b)(3), §(9607(q); and §9607(r)), assuming compliance with other elements of the defense.

Approximate minimum search distance – the area for which records must be obtained and reviewed pursuant to Section 8 subject to the limitations provided in that section. This may include areas outside the property and shall be measured from the nearest property boundary. This term is used in lieu of radius to include irregularly shaped properties.

Bona fide prospective purchaser liability protection – (42 U.S.C. §9607(r) – a person may qualify as a bona fide prospective purchaser if, among other requirements, such person made “all appropriate inquiries into the previous ownership and uses of the facility in accordance with generally accepted good commercial and customary standards and practices.” Knowledge of contamination resulting from all appropriate inquiry would not generally preclude this liability protection. A person must make all appropriate inquiries on or before the date of purchase. The facility must have been purchased after January 11, 2002.

Brownfields Amendments – amendments to CERCLA pursuant to the Small Business Liability Relief and Brownfields Revitalization Act, Pub. L. No. 107-118 (2002), 42 U.S.C. §§9601 et. seq.

Building department records – those records of the local government in which the property is located indicating permission of the local government to construct, alter, or demolish improvements on the property. Often building department records are located in the building department of a municipality or county.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | A-2 Appendix A | ASTM Terminology

Business environmental risk – a risk which can have a material environmental or environmentally-driven impact on the business associated with the current or planned use of a parcel of commercial real estate, not necessarily limited to those environmental issues required to be investigated in this practice. Consideration of business environmental risk issues may involve addressing one or more non-scope considerations, some of which are identified in Section 13.

Commercial real estate – any real property except a dwelling or property with no more than four dwelling units exclusively for residential use (except that a dwelling or property with no more than four dwelling units exclusively for residential use is included in this term when it has a commercial function, as in the building of such dwellings for profit). This term includes but is not limited to undeveloped real property and real property used for industrial, retail, office, agricultural, other commercial, medical, or educational purposes: property used for residential purposes that has more than four residential dwelling units; and property with no more than four dwelling units for residential use when it has a commercial function, as in the building of such dwellings for profit.

Commercial and real estate transaction – a transfer of title to or possession of real property or receipt of a security interest in real property, except that it does not include transfer of title to or possession of real property or the receipt of a security interest in real property or the receipt of a security interest in real property with respect to an individual dwelling or building containing fewer than five dwelling units, nor does it include the purchase of a lot or lots to construct a dwelling for occupancy by a purchaser, but a commercial real estate transaction does include real property purchased or leased by persons or entities in the business of building or developing dwelling units.

Comprehensive Environmental Response, Compensation, and Liability Information System (CERCLIS) – the list of sites compiled by EPA that EPA has investigated or is currently investigating for potential hazardous substance contamination for possible inclusion on the National Priorities List.

Construction debris – concrete, brick, asphalt, and other such building materials discarded in the construction of a building or other improvement to property.

Contaminated public wells – public wells used for drinking water that have been designated by a government entity as contaminated by hazardous substances (for example, chlorinated solvents), or as having water unsafe to drink without treatment.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | A-3 Appendix A | ASTM Terminology

Contiguous property owner liability protection – (42 U.S.C. §9607(q) – a person may qualify for the contiguous property owner liability protection if, among other requirements, such person owns real property that is contiguous to, and that is or may be contaminated by hazardous substances from other real property that is not owned by that person. Furthermore, such person conducted all appropriate inquiries at the time of acquisition of the property and did not know or have reason to know that the property was or could be contaminated by a release or threatened release from the contiguous property. The all appropriate inquiries must not result in knowledge of contamination. If it does, then such person did “know” or “had reason to know” of contamination and would not be eligible for the contiguous property owner liability protection. See Appendix X1 for the other necessary requirements that are beyond the scope of this practice.

Controlled recognized environmental condition – a recognized environmental condition resulting from a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority (for example, as evidenced by the issuance of a no further action letter or equivalent, or meeting risk- based criteria established by regulatory authority), with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls). (See Note 2). A condition considered by the environmental professional to be controlled recognized environmental condition shall be listed in the findings section of the Phase I Environmental Site Assessment report, and as a recognized environmental condition in the conclusions section of the Phase I Environmental Site Assessment report. (See Note 3).

Note 2 — For example, if a leaking underground storage tank has been cleaned up to a commercial use standard, but does not meet unrestricted residential cleanup criteria, this would be considered a controlled recognized environmental condition. The “control” is represented by the restriction that the property use remains commercial. Note 3 — A condition identified as a controlled recognized environmental condition does not imply that the environmental professional has evaluated or confirmed the adequacy, implementation, or continued effectiveness of the required control that has been, or is intended to be implemented.

CORRACTS list – a list maintained by EPA of hazardous waste treatment, storage, or disposal facilities and other RCRA-regulated facilities (due to past interim status or storage of hazardous waste beyond 90 days) that have been notified by the U.S. Environmental Protection Agency to undertake corrective action under RCRA. The CORRACTS list is a subset of the EPA database that manages RCRA data.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | A-4 Appendix A | ASTM Terminology

Data failure – a failure to achieve the historical research objectives in 8.3.1 through 8.3.2.2 even after reviewing the standard historical sources 8.3.4.1 through 8.3.4.8 that are reasonably ascertainable and likely to be useful. Data failure is one type of data gap. See 8.3.2.3.

Data gap – a lack of or inability to obtain information required by this practice despite good faith efforts by the environmental professional to gather such information. Data gaps may result from incompleteness in any of the activities required by this practice, including, but not limited to site reconnaissance (for example, an inability to conduct the site visit), and interviews (for example, an inability to interview the key site manager, regulatory officials, etc.). See 12.7.

Demolition debris – concrete, brick, asphalt, and other such building materials discarded in the demolition of a building or other improvement to property.

De minimis condition – a condition that generally does not present a threat to human health or the environment and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. Conditions determined to be de minimis conditions are not recognized environmental conditions nor controlled recognized environmental conditions.

Drum – a container (typically, but not necessarily, holding 55 gal (208 L) of liquid) that may be used to store hazardous substances or petroleum products.

Dry wells – underground areas where soil has been removed and replaced with pea gravel, coarse sand, or large rocks. Dry wells are used for drainage, to control storm runoff, for the collection of spilled liquids (intentional and non-intentional) and wastewater disposal (often illegal).

Due diligence – the process of inquiring into the environmental characteristics of a parcel of commercial real estate or other conditions, usually in connection with a commercial real estate transaction. The degree and kind of due diligence vary for different properties and differing purposes. See Appendix X1.

Dwelling – structure or portion thereof used for residential habitation.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | A-5 Appendix A | ASTM Terminology

Engineering controls (EC) – physical modifications to a site or facility (for example, capping, slurry walls, or point of use water treatment) to reduce or eliminate the potential for exposure to hazardous substances or petroleum products in the soil or groundwater on the property. Engineering controls are a type of activity and use limitation (AUL).

Environment – environment shall have the same meaning as the definition of environment in CERCLA 42 U.S.C. § 9601 (8). For additional background information, see Legal Appendix (Appendix X1) to section XI. 1.1 “Releases and Threatened Release.” Environmental compliance audit – the investigative process to determine if the operations of an existing facility are in compliance with applicable environmental laws and regulations. This term should not be used to describe this practice, although an environmental compliance audit may include an environmental site assessment or, if prior audits are available, may be part of an environmental site assessment.

Environmental lien – a charge, security, or encumbrance upon title to a property to secure the payment of a cost, damage, debt, obligation, or duty arising out of response actions, cleanup, or other remediation of hazardous substances or petroleum products upon a property, including (but not limited to) liens imposed pursuant to CERCLA 42 U.S.C. §§9607(1) & 9607(r) and similar state or local laws.

Environmental professional – a person meeting the education, training, and experience requirements as set forth in 40 CFR §312.10(b). For the convenience of the reader, this section is reprinted in Appendix X2. The person may be an independent contractor or an employee of the user.

Environmental site assessment (ESA) – the process by which a person or entity seeks to determine if a particular parcel of real property (including improvements) is subject to recognized environmental conditions. At the option of the user, an environmental site assessment may include more inquiry than that constituting all appropriate inquiries or, if the user is not concerned about qualifying for the LLPs, less inquiry than that constituting all appropriate inquiries. An environmental site assessment is both different from and often less rigorous than an environmental compliance audit.

ERNS list – EPA’s emergency response notification system list of reported CERCLA hazardous substance releases or spills in quantities greater than the reportable quantity, as maintained at the National Response center. Notification requirements for such releases or spills are codified in 40 CFR Parts 302 and 335.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | A-6 Appendix A | ASTM Terminology

Federal Register (FR) – publication of the United States government published daily (except for federal holidays and weekends) containing all proposed and final regulations and some other activities of the Federal Government. When regulations become final, they are included in the Code of Federal Regulations (CFR), as well as published in the Federal Register.

Fill dirt – dirt, soil, sand, or other earth, that is obtained off-site, that is used to fill holes or depressions, create mounds, or otherwise artificially change the grade or elevation or real property. It does not include material that is used in limited quantities for normal landscaping activities.

Fire insurance maps – maps produced for private fire insurance map companies that indicate uses of properties at specified dates and that encompass the property. These maps are often available at local libraries, historical societies, private resellers, or from the map companies who produced them.

Good faith – the absence of any intention to seek an unfair advantage or to defraud another party; an honest and sincere intention to fulfill one’s obligations in the conduct or transaction concerned.

Hazardous substance – a substance defined as a hazardous substance pursuant to CERCLA 42 U.S.C. §9601(14), as interpreted by EPA regulations and the courts: “(A) any substance designated pursuant to section 1321(b)(2)(A) of Title 33, (B) any element, compound, mixture, solution, or substance designated pursuant to section 9602 of this title, (C) any hazardous waste having the characteristics identified under or listed pursuant to section 3001 of the Resource Conservation and Recovery Act of 1976 (RCRA), as amended, (42 U.S.C. §6921) (but not including any waste the regulation of which under RCRA (42 U.S.C. §§6901 et seq.) has been suspended by Act of Congress, (D) any toxic pollutant listed under section 1317(a) of Title 33, (E) any hazardous air pollutant listed under section 112 of the Clean Air Act (42 U.S.C. §7412), and (F) any imminently hazardous chemical substance or mixture with respect to which the Administrator (of EPA) has taken action pursuant to section 2606 of Title 15. The term does not include petroleum, including crude oil or any fraction thereof which is not otherwise specifically listed or designated as a hazardous substance under subparagraphs (A) through (F) of this paragraph, and the term does not include natural gas, natural gas liquids, liquefied natural gas, or synthetic gas usable for fuel (or mixtures of natural gas and such synthetic gas).” (See Appendix X1.)

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | A-7 Appendix A | ASTM Terminology

Hazardous waste – any hazardous waste having the characteristics identified under or listed pursuant to section 3001 of RCRA, as amended, (42 U.S.C. §6921) (but not including any waste the regulation of which under RCRA (42 U.S.C. §§6901-6992(k) has been suspended by Act of Congress). RCRA is sometimes also identified as the Solid Waste Disposal Act. RCRA defines a hazardous waste, at 42 U.S.C. §6903, as: “a solid waste, or combination of solid wastes, which because of its quantity, concentration, or physical, chemical, or infectious characteristics may – (A) cause, or significantly contribute to an increase in mortality or an increase in serious irreversible, or incapacitating reversible, illness; or (B) pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, or disposed of, or otherwise managed.”

Hazardous waste/contaminated sites – sites on which a release has occurred, or is suspected to have occurred, of any hazardous substance, hazardous waste, or petroleum products, and that release or suspected release has been reported to a government entity.

Historical recognized environmental condition – a past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority or meeting unrestricted use criteria established by a regulatory authority, without subjecting the property to any required controls (for example, property use restrictions, activity and use limitations, institutional controls, or engineering controls). Before calling the past release a historical recognized environmental condition, the environmental professional must determine whether the past release is a recognized environmental condition at the time the Phase I Environmental Site Assessment is conducted (for example, if there has been a change in the regulatory criteria). If the EP considers the past release to be a recognized environmental condition at the time the Phase I ESA is conducted, the condition shall be included in the conclusions section of the report as a recognized environmental condition.

IC/EC registries – databases of institutional controls or engineering controls that may be maintained by a federal, state or local environmental agency for purposes of tracking sites that may contain residual contamination and AULs. The names for these may vary from program to program and state to state, and include terms such as Declaration of Environmental Use Restriction database (Arizona), list of “deed restrictions” (California), environmental real covenants list (Colorado), brownfields site list (Indiana, Missouri, Pennsylvania), and the Pennsylvania Activity and Use Limitation (PA AUL) Registry.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | A-8 Appendix A | ASTM Terminology

Innocent landowner defense – (42 U.S.C. §§9601(35) and 9607(b)(3)) – a person may qualify as one of three types of innocent landowners: (i) a person who “did not know and had no reason to know” that contamination existed on the property at the time the purchaser acquired the property; (ii) a government entity which acquired the property by escheat, or through any other involuntary transfer or acquisition, or through the exercise of eminent domain authority by purchase or condemnation; and (iii) a person who “acquired the facility by inheritance or bequest.” To qualify for the first type of innocent landowner defense, such person must have made all appropriate inquiries on or before the date of purchase. Furthermore, the all appropriate inquiry must not have resulted in knowledge of the contamination. If it does, then such person did “know” or “had reason to know” of contamination and would not be eligible for the innocent landowner defense. See Appendix X1 for the other necessary requirements that are beyond the scope of this practice.

Institutional controls (IC) – a legal or administrative restriction (for example, “deed restrictions,” restrictive covenants, easements, or zoning) on the use of, or access to, a site or facility to (1) reduce or eliminate potential exposure to hazardous substances or petroleum products in the soil or groundwater on the property, or (2) to prevent activities that could interfere with the effectiveness of a response action, in order to ensure maintenance of a condition of no significant risk to public health or the environment. An institutional control is a type of Activity and Use Limitation (AUL).

Interviews – those portions of this practice that are contained in Section 10 and 11 thereof and address questions to be asked of past and present owners, operators, and occupants of the property and questions to be asked of local government officials.

Key site manager – the person identified by the owner or operator of a property as having good knowledge of the uses and physical characteristics of the property. See 10.5.1.

Landfill – a place, location, tract of land, area, or premises used for the disposal of solid wastes as defined by state solid waste regulations. The term is synonymous with the term solid waste disposal site and is also known as a garbage dump, trash dump, or similar term.

Landowner Liability Protections (LLPs) – landowner liability protections under CERCLA; these protections include the bona fide prospective purchaser liability protection, contiguous property owner liability protection, and innocent landowner defense from CERCLA liability. See 42 U.S.C. §§9601(35)(A), 9601(40), 9607(b), 9607(q), 9607(r).

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | A-9 Appendix A | ASTM Terminology

Local government agencies – those agencies of municipal or county government having jurisdiction over the property. Municipal and county government agencies include but are not limited to cities, parishes, townships, and similar entities.

Local street directories – directories published by private (or sometimes government) sources that show ownership, occupancy, and/or use of sites by reference to street addresses. Often local street directories are available at libraries, or historical societies, and/or local municipal offices. See 8.3.4.6 of this practice.

LUST sites – state lists of leaking underground storage tank sites. RCRA gives EPA and states, under cooperative agreements with EPA, authority to clean up releases from UST systems or require owners and operators to do so. (42 U.S.C. §6991b).

Major occupants – those tenants, subtenants, or other persons or entities each of which uses at least 40% of the leasable area of the property or any anchor tenant when the property is a shopping center.

Material safety data sheet (MSDS) – written or printed material concerning a hazardous substance which is prepared by chemical manufacturers, importers, and employers for hazardous chemicals pursuant to OSHA’s Hazard Communication Standard, 29 C.F.R. §1910.1200.

Material threat – A physically observable or obvious threat which is reasonably likely to lead to a release that, in the opinion of the environmental professional, is threatening and might result in impact to public health or the environment. An example might include an aboveground storage tank system that contains a hazardous substance and which shows evidence of damage. The damage would represent a material threat if it is deemed serious enough that it may cause or contribute to tank integrity failure with release of contents to the environment.

Migrate/migration – for the purposes of this practice, “migrate” and “migration” refers to the movement of hazardous substances or petroleum products in any form, including, for example, solid and liquid at the surface or subsurface, and vapor in the subsurface. See Note 4.

Note 4 — Vapor migration in the subsurface is described in Guide E2600; however, nothing in this practice should be construed to require application of the Guide E2600 standard to achieve compliance with all appropriate inquiries.

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | A-10 Appendix A | ASTM Terminology

National Contingency Plan (NCP) – the National Oil and Hazardous Substances Pollution Contingency Plan, found at 40 C.F.R. Part 300, that is the EPA’s blueprint on how hazardous substances are to be cleaned up pursuant to CERCLA.

National Priorities List (NPL) – list compiled by EPA pursuant to CERCLA 42 U.S.C. §9605(a)(8)(B) of properties with the highest priority for cleanup pursuant to EPA’s Hazard Ranking System. See 40 C.F.R. Part 300.

Obvious – that which is plain or evident; a condition or fact that could not be ignored or overlooked by a reasonable observer while visually or physically observing the property.

Occupants – those tenants, subtenants, or other persons or entities using the property or a portion of the property.

Operator – the person responsible for the overall operation of a facility.

Other historical sources – any source or sources other than those designated in Sections 8.3.4.1 through 8.3.4.8 that are credible to a reasonable person and that identify past uses of the property. The term includes, but is not limited to: miscellaneous maps, newspaper archives, internet sites, community organizations, local libraries, historical societies, current owners or occupants of neighboring properties, and records in the files and/or personal knowledge of the property owner and/or occupants. See 8.3.4.9.

Owner – generally the fee owner of record of the property.

Petroleum exclusion – the exclusion from CERCLA liability provided in 42 U.S.C. §9601(14), as interpreted by the courts and EPA: “The term (hazardous substance) does not include petroleum, including crude oil or any fraction thereof which is not otherwise specifically listed or designated as a hazardous substance under subparagraphs (A) through (F) of this paragraph, and the term does not include natural gas, natural gas liquids, liquefied natural gas, or synthetic gas usable for fuel (or mixtures of natural gas and such synthetic gas).”

Petroleum products – those substances included within the meaning of the petroleum exclusion to CERCLA, 42 U.S.C. §9601(14), as interpreted by the courts and EPA, that is: petroleum, including crude oil or any fraction thereof which is not otherwise specifically

Aviation Boulevard at Artesia Boulevard Southbound to Westbound Right Turn Improvement Project Phase I ESA | A-11 Appendix A | ASTM Terminology

listed or designated as a hazardous substance under Subparagraphs (A) through (F) of 42 U.S.C. §9601(14), natural gas, natural gas liquids, liquefied natural gas, and synthetic gas usable for fuel (or mixtures of natural gas and such synthetic gas). (The word fraction refers to certain distillates of crude oil, including gasoline, kerosene, diesel oil, jet fuels, and fuel oil, pursuant to Standard Definitions of Petroleum Statistics. )

Phase I Environmental Site Assessment – the process described in this practice.

Physical setting sources – sources that provide information about the geologic, hydrogeologic, hydrologic, or topographic characteristics of a property. See 8.2.4. Pits, ponds, or lagoons – man-made or natural depressions in a ground surface that are likely to hold liquids or sludge containing hazardous substances or petroleum products. The likelihood of such liquids or sludge being present is determined by evidence of factors associated with the pit, pond, or lagoon, including, but not limited to, discolored water, distressed vegetation, or the presence of an obvious wastewater discharge.

Practically reviewable – information that is practically reviewable means that the information is provided by the source in a manner and in a form that, upon examination, yields information relevant to the property without the need for extraordinary analysis of irrelevant data. The form of the information shall be such that the user can review the records for a limited geographic area. Records that cannot be feasibly retrieved by reference to the location of the property or a geographic area in which the property is located are not generally practically reviewable. Most databases of public records are practically reviewable if they can be obtained from the source agency by the county, city, zip code, or other geographic area of the facilities listed in the record system. Records that are sorted, filed, organized, or maintained by the source agency only chronologically are not generally practically reviewable. Listings in publicly available records which do not have adequate address information to be located geographically are not generally considered practically reviewable. For large databases with numerous records (such as RCRA hazardous waste generators and registered underground storage tanks), the records are not practically reviewable unless they can be obtained from the source agency in the smaller geographic area of zip codes. Even when information is provided by zip code for some large databases, it is common for an unmanageable number of sites to be identified within a given zip code. In these cases, it is not necessary to review the impact of all of the sites that are likely to be listed in any given zip code because that information would not be practically reviewable. In other words, when so much data is generated that it cannot be feasibly reviewed for its impact on the property, it is not practically reviewable.

Subject: FINAL CLOSURE REPORT FOR EXXONMOBIL OIL CORPORATION FORMER SERVICE STATION #18-EBK 1727 ARTESIA BOULEVARD, MANHATTAN BEACH, CALIFORNIA (CRWQCB-LAR ID #R-09354A)

Dear Ms. Hsu:

Holguin, Fahan & Associates, Inc. (HFA), on behalf of ExxonMobil Oil Corporation (ExxonMobil), is pleased to present the following final closure letter to document current site conditions at the subject site. In an Underground Tank Program - Case Closure letter dated July 10, 2007, the CRWQCB-LAR required that a well abandonment report be submitted by October 31, 2007 (see Attachment 1 for the regulatory correspondence). A list of acronyms used in this report is enclosed.

SITE HISTORY

In 1988, the first generation of USTs was removed from the northwestern portion of the site and replaced with the second generation of USTs in the northeastern portion of the site (see Figure 1 - Plot Plan). Results of compliance sampling indicated that the maximum adsorbed-phase hydrocarbon concentrations were measured in the vicinity of the former first generation southern dispenser islands (Alton Geoscience, 1996).

Groundwater monitoring was performed from 1987 to 1998. Results of the groundwater monitoring indicated that dissolved-phase benzene was localized to the western portion of the site, and concentrations showed a declining trend by more than an order of magnitude after the completion of remedial activities in 1996. During the final monitoring events, MTBE was added to the monitoring program and was detected for only one well, at a concentration only slightly in excess of the primary drinking water MCL (Kleinfelder, 1998). Ms. Mercedes Hsu CRWQCB-LAR October 2, 2007 - Page 2

The CRWQCB-LAR granted the site closure in its letter dated September 4, 1998, and all wells were abandoned.

In March 2002, a baseline environmental assessment of the site was conducted. Laboratory analytical results for the soil samples indicated only two detections of TPH as gasoline (maximum of 2.4 mg/kg at 30 fbg) and one detection of MTBE (0.16 mg/kg at 20 fbg). Benzene was not detected for any of the soil samples (HFA, 2002).

In March 2003, the service station was abandoned. In May 2005, three additional soil borings were drilled to delineate the vertical extent of residual adsorbed-phase hydrocarbons detected beneath the former fueling facilities. Laboratory analytical results for two soil borings indicated no TPH as gasoline, benzene, or MTBE concentrations above laboratory reporting limits. Laboratory analytical results for the soil samples collected from soil boring B-8 indicated a maximum benzene concentration of 0.0247 mg/kg at 20 fbg, and no detections of TPH as gasoline or MTBE above laboratory reporting limits. Benzene concentrations attenuated at depths greater than 20 fbg and were not measured at the capillary fringe (85 fbg). Laboratory analytical results for a grab groundwater sample collected from the bottom of soil boring B-8 indicated no detections of TPH as gasoline, benzene, MTBE, or TBA (HFA, 2005).

On March 8, 2007, a secondary excavation was conducted to remove hydrocarbon-containing soil in the vicinity of historical sample EX-B-1-10. This sample contained the highest adsorbed-phase MTBE concentration (31 mg/kg) measured at the site. The excavation was conducted to 19 fbg to remove hydrocarbon-containing soil from 9 to 19 fbg. Two verification soil samples (EX-1-19 and EX-2-19) were collected from the bottom of the excavation, and these samples indicated no detections of hydrocarbons (HFA, 2007). The 9.23 tons of hydrocarbon-containing soil excavated from 9 to 19 fbg was transported off-site for recycling to TPS Technologies’ facility in Adelanto, California.

Based upon these site conditions, CRWQCB-LAR granted the site closure in its letter dated July 10, 2007 (see Attachment 1).

CURRENT SITE CONDITIONS

This letter certifies that there are no remaining groundwater monitoring or vapor extraction wells associated with the site, and that all site closure conditions have been met. Ms. Mercedes Hsu CRWQCB-LAR October 2, 2007 - Page 3

Holguin, Fahan & Associates, Inc. trusts that this final closure report meets your requirements. If you have any questions or require additional information, please contact me at (805) 641-4089 or [email protected].

UNDERGROUNDSTORAGETANKPROGRAM-CASEREFERRALRESPONSE SOUTH BAY SHELL 1700 ARTESIA BOULEVARD, REDONDO BEACH, CALIFORNIA (GLOBAL ID NO.: T10000007166)

Dear Mr. Madani:

On July 14, 2015, the County of Los Angeles Department of Public Works transmitted this case to our agency due to concerns regarding soil and groundwater impacts from the subject site (Site). · The California Regional Water Quality Control Board, Los Angeles Region (Regional Board), is the public agency with primary responsibility for the protection of ground and surface water quality for all beneficial uses within the Los Angeles and Ventura counties. As such, we are the lead regulatory agency for overseeing corrective actions (assessment and/or monitoring activities) and cleanup of releases from leaking u.nderground storage tank (UST) systems at the Site.

We have received the following document for the Site:

);> "Environmental Oversight of Product Piping Removal and Soil Sampling Activities" report dated March 22, 2010, prepared by Wayne Perry, Inc.

Based on our review of the submitted document, we have the following comments:

• In January 2010, product piping and vent lines were replaced with new piping and vent lines. Eighteen soil samples were collected approximately 3.5 feet below the former product piping and vent lines and submitted for analytical testing.

• All soil samples were analyzed for total petroleum hydrocarbons as gasoline (TPHg) by EPA Method 8015B, and benzene, toluene, ethylbenzene, and xylenes (BTEX), ethanol, and fuel oxygenates (di-isopropyl ether [DIPE], ethyl tertiary butyl ether [ETBE], methyl tertiary butyl ether [MTBE], tertiary amyl methyl ether [TAME], and tertiary butyl alcohol [TBA]) by EPA Method 8260B.

• Laboratory results indicated maximum detected concentration of TPHg, ethylbenzene, and xylenes were 0.4J milligrams per kilogram (mg/kg) 0.001J mg/kg, and 0.003 · mg/kg, respectively. Benzene, toluene, ethanol and fuel oxygenates were not detected at or above their respective reporting limits in either soil sample collected in January 2010.

• Groundwater was not encountered at the Site during transfer piping and vent line replacement activities.

Based on the information available to us, Regional Board staff determined that residual concentrations of fuel constituents pose a low threat to human health, and soil and groundwater quality beneath the Site. Therefore, no further action is required to pursue any further soil and/or groundwater investigation at the Site. No Regional Board case for the Site will be opened at this time.

If you have any questions, please contact Dr. Weixing Tong at (213) 576-6715 or email him at [email protected]

SITE DESCRIPTION

The site is currently occupied by an active Shell service station. There are three 10,000 gallon underground storage tanks (USTs) containing gasoline with associated product piping. Main features of the site are shown on Figure 2.

PRODUCT PIPING REMOVAL ACTIVITIES

WPI provided environmental oversight during excavation activities conducted to replace product line piping and performed soil sampling at the site from January 6 to 7, 2010. Excavated soil was monitored for volatile organic compounds using aphoto-ionization detector (PID) calibrated to hexane in accordance with WPI's South Coast Air Quality Management District(SCAQMD) Rule ]166 Mitigation Plan No. 494846 under Reference Number 233353. PID readings did not exceed 50 ppm during excavation activities. Copies of the SCAQMD Rule 1166 notification forms and 1166 monitoring records are provided in Appendix A.

On January 7, 2010, the product lines were cleaned and triple rinsed, under permit number 136669. Copies of LADPW permits are in Attachment B.

The old product and vent lines were cut and removed for recycling and new double-walled fiberglass lines were installed. The removed product and vent lines were disposed of as non- RCRA hazardous waste. Copies of the waste disposal receipts are provided in Attachment C.

SOIL SAMPLING ACTIVITIES

On January 7, 2010, WPI personnel collected a total of eighteen soil samples from approximately 3.5 feet below the former product and UST vent piping. Two stockpile samples were also collected. Soil sample locations are shown on Figure 2.

All soil samples were collected using a hand auger and preserved for volatile analyses using the EPA 5035 Protocol. Aback up sample was packed into a brass tube, sealed at each end with Teflon sheets and capped with plastic end caps. All samples were labeled, stored on ice, and transported under chain-of-custody to Alpha Scientific Corporation of Cerritos, California. Soil sampling activities were performed under the supervision of a California Professional Geologist.

All samples collected were analyzed for total petroleum hydrocarbons as gasoline(TPH-G) using EPA Method 8015 and benzene, toluene, ethylbenzene, total xylenes and oxygenated compounds using EPA Method 8260.

Soil analytical results are summarized in Table 1 and on Figure 2. Copies of the laboratory reports and chain-of-custody documents are provided in Attachment D. March 22, 2010 Shell Service Station 1700 Artesia Boulevard, Redondo Beach Page 3

SOIL SAMPLING ANALYTICAL RESULTS

DISPENSERS

TPH-G and ethylbenzene were detected in soil sample D 1 collected from below the location shown on figure 2 at concentrations of 0.45 and 0.003 mg/kg, respectively. These results do not exceed LADPW action levels. Ethylbenzene and xylenes were detected in soil sample D4 (0.001 J mg/kg). Total xylenes were detected in soil samples D4 at concentrations of 0.001 J and 0.0015J mg/kg, respectively. These concentrations are also below action levels.

Oxygenated compounds were not detected in any of the product line, soil stockpile or dispenser samples.

CONCLUSIONS

Based on these analytical results, WPI concludes that no further actions related to these upgrade activities are required. March 22, 20l 0 Shell Service Station 1700 Artesia Boulevard, Redondo Beach Page 4

Re: Closure Request / Remedial Action Plan Former Shell Service Station 1650 Artesia Boulevard Redondo Beach, California Case No. R-26321

Dear Dr. Tong:

On behalf of Equilon Enterprises LLC dba Shell Oil Products US (SHELL), Delta Consultants (Delta) respectfully submits this Closure Request / Remedial Action Plan (RAP) for the above-referenced site (Figure 1). The purpose of this document is to present an evaluation of remedial alternatives to address the petroleum hydrocarbons identified in soil and groundwater beneath the site.

Based on a detailed review of historical data, Delta is recommending that no further action be performed as any residual petroleum hydrocarbons will naturally degrade.

This document has been prepared to comply with the California Code of Regulations, Title 23, Division 3, Chapter 16, and Article 11. Provided below is site background information followed by a detailed evaluation of remedial alternatives.

SITE BACKGROUND

SITE DESCRIPTION

The site is located on the southwest corner of the intersection of Artesia Boulevard and Aviation Boulevard in Redondo Beach, California (Figures 1 and 2). The site is a former Shell service station. Three 10,000-gallon gasoline underground storage tanks (USTs), one 550-gallon waste oil UST, five product dispensers, three hoists, one clarifier, and associated product piping were removed from the site in February 1999. The site is a two-story, eight-unit condominium complex with one level of underground parking.

The site is approximately 100 feet above mean sea level (msl). The topography across the site generally slopes towards Aviation Boulevard. The vicinity of the site is mixed commercial and residential with a Shell service station and an EZ Lube facility located to the east across Aviation Boulevard, a strip mall and a surf shop to the northeast across the intersection of Artesia Boulevard and Aviation Boulevard, a vacant service station to the north across Artesia Boulevard, and residential structures (including single-family and multi-family properties) to the west and south of the site.

GEOLOGY AND HYDROGEOLOGY

REGIONAL GEOLOGY AND HYDROGEOLOGY

The site is located in the Los Angeles Coastal Plain within the West Coast Basin Area at an elevation of approximately 100 feet above mean sea level (msl). Sediments beneath the site are primarily older dune sand of Upper Pleistocene age which extends to approximately 120 feet below ground surface (bgs). The site is located in the El Segundo Sand Hills which extend from Ballona Gap south to Torrance and the Palos Verdes Hills, and approximately three to four miles inland from the ocean. The older sand dunes overlie silts and clays which apparently were deposited on the landward side of the beach sands and which now form a portion of the Torrance Plain (CDWR, 1961).

Major aquifers beneath the site in order of increasing depth include the Gage and the Lynwood - Silverado. The Lynwood and Silverado Aquifers are merged in this area. Overlying the Gage Aquifer is the Bellflower Aquiclude which is approximately 30 feet thick in the area around the site and is found approximately 150 to 180 feet bgs. The Gage Aquifer extends from a depth of approximately 180 to 210 feet bgs. The regional groundwater gradient is toward the east - northeast (PEG, 1998).

The site is also located just east of the West Coast Barrier Project, which runs along Pacific Coast Highway and extends north along Sepulveda Blvd. The barrier consists of a network of groundwater injection wells that protect fresh groundwater resources from salt-water intrusion by maintaining a groundwater divide parallel to the coastline. This has apparently caused groundwater on the eastern side of the barrier to flow to the east, and away from the ocean (PEG, 1998).

SITE SPECIFIC GEOLOGY AND HYDROGEOLOGY

Soils encountered during monitoring well installation activities in July 2002 were predominantly sand and silty sand from the surface to the total depth explored of approximately 101 feet bgs. Boring locations are shown on April 22, 2010 1650 Artesia Blvd., Redondo Beach, California Closure Request / Remedial Action Plan Page 7

Figure 2. Lithological data is also presented in cross-section view in Figures 3 through 5, and historic boring logs are provided in Appendix B.

During the most recent gauging of wells on November 23, 2009, the depth to groundwater ranged from 72.80 to 73.70 feet below the top of well casings. The groundwater gradient at that time was easterly at approximately 0.002 feet per foot (ft/ft). Groundwater was generally first encountered during drilling at depths ranging from approximately 75 to 86 feet bgs. Groundwater has risen approximately 13 feet in well MW-1, approximately 5 feet in well MW-2, and approximately 1 foot in well MW-3 since gauging events began March 31, 2001. Historical groundwater data is presented in Table 5. A groundwater elevation contour map is presented as Figure 6. A rose diagram of historic groundwater flow direction based on quarterly monitoring events is included in Appendix C. As depicted in the diagram, historical groundwater flow direction has been predominantly to the east, with an average gradient of 0.007 ft/ft.

SOURCE REMOVAL

The USTs, piping, dispensers, hoists, and a clarifier were removed from the site in February 1999. The site has not been operated as a service station since that time.

HYDROCARBON DISTRIBUTION IN SOIL

In May 1999, three 10,000-gallon USTs, one 550-gallon waste oil UST, five product dispensers, three hoists, one clarifier, and all associated product piping were removed from the site. TPH-g, benzene, toluene, ethyl benzene, and total xylenes (BTEX compounds) were detected in one sample collected beneath the eastern UST at a depth of 15 feet bgs (T-3B). TPH-g and benzene were reported at concentrations of 200 mg/kg and 0.18 mg/kg, respectively. MTBE was detected in soil samples collected beneath the USTs and southern fuel dispensers (approximately 2.5 feet bgs), with concentrations ranging from 0.41 mg/kg to 20 mg/kg (T-3B). TPH-g, BTEX, and MTBE were not detected above the laboratory reporting limits in samples collected beneath Dispensers 4 and 5, north of the UST complex. Three soil samples were collected beneath the former hoists (H1 through H3) and one sample was collected beneath the former clarifier (C1); total recoverable petroleum hydrocarbons (TRPH) were reported in all four samples with concentrations ranging from 16 mg/kg and 149 mg/kg. Please note that, although PEG’s historical soil analytical tables indicate that soil samples were collected beneath the USTs at 3 to 4 feet bgs, typical samples collected beneath USTs are at depths of 15 feet bgs. As stated in the text of PEG’s Underground Storage Tank Closure Report, dated May 20, 1999, the sample depths were denoted as 15 feet bgs.

In September 1999, PEG evaluated the vertical and lateral extent of petroleum hydrocarbon and MTBE impacts in soil near the UST complex, the waste oil tank, the fuel dispensers south of the UST complex, and the hydraulic hoist area inside the building. Eleven soil borings were completed, and four grab groundwater samples were collected. TPH-g, ethylbenzene, toluene, and total xylenes were detected in soil samples collected in the area of the USTs (borings B-5 and B-7 located east and southeast of the former UST complex) primarily from a depth of 20 to 50 feet bgs. The maximum TPH-g concentration reported was 6,100 mg/kg at 45 feet bgs in boring B-7. MTBE was detected in four shallow soil samples (above 25 feet bgs) with a maximum reported concentration of 4.7 mg/kg in boring B-6. Borings B-8 and B-9 were drilled adjacent to the former hydraulic hoists to 20 feet bgs; all analytical parameters were below the laboratory reporting limits including TRPH. Boring B-11 was drilled April 22, 2010 1650 Artesia Blvd., Redondo Beach, California Closure Request / Remedial Action Plan Page 8 adjacent to the former waste oil tank to a depth of 90 feet bgs. Four samples between the depths of 40 and 90 feet bgs were analyzed from this boring and analytes were below the laboratory reporting limits (PEG’s Subsurface Investigation, 1999).

IT’s Groundwater Assessment Report, dated January 12, 2001, presented assessment data that further defined the extent of hydrocarbon-impacted soil and groundwater beneath the site. Three borings were drilled and converted to wells MW-1, MW-2, and MW-3. TPH-g was detected in two soil samples at concentrations of 1.2 mg/kg from 60 feet bgs in MW-1 and 1.1 mg/kg from 65 feet bgs in MW-2. MTBE was reported in five samples collected between the depths of 35 and 80 feet bgs with concentrations ranging from 0.0016 to 0.05 mg/kg (80 feet bgs in MW-3).

In September 2002, KHM conducted additional soil and groundwater sampling activities and installed wells MW-4 through MW-8. TPH-g was reported in soil samples from wells MW-4 through MW-7 between depths of 15 and 85 feet bgs in well MW-4, 65 and 80 feet in well MW-5, 80 and 85 feet in well MW-6, and at 90 feet in well MW- 7. The maximum concentration of TPH-g detected in soil samples was 6,700 mg/kg (MW-4d35). BTEX compounds were reported in soil samples from wells MW-4, MW-5, MW-6 between depths of 15 and 35 feet from well MW-4, 75 and 80 feet in well MW-5, and 80 and 85 feet in well MW-6. The maximum concentration of benzene detected in soil samples was 0.0093 mg/kg (MW-6d80). The maximum concentrations of toluene, ethylene, and total xylenes detected in soil samples were 3.1 mg/kg, 1.4 mg/kg, and 25.6 mg/kg, respectively (MW- 4d25). MTBE was reported in soil samples from wells MW-4 through MW-8 at a depth of 15 feet bgs in well MW-4, between depths of 40 and 90 feet bgs in well MW-5, 65 and 85 feet in well MW-6, 70 and 85 feet in well MW-7, and 75 and 90 feet in well MW-8. The maximum concentration of MTBE detected in soil samples was 0.79 mg/kg (MW-6d80). Tert-butyl alcohol (TBA) was reported in soil samples from wells MW-4 through MW-7 between depths of 15 and 85 feet bgs in well MW-4, 40 and 90 feet bgs in well MW-5, 70 and 90 feet in well MW- 6, and at 85 feet in well MW-7. The maximum concentration of TBA detected in soil samples was 1.1 mg/kg (MW-5d70 and MW-6d70). Di-isopropyl ether (DIPE) was reported in soil samples from wells MW-4 through MW-7 at a depth of 85 feet bgs in well MW-4, between depths of 75 and 90 feet bgs in well MW-5, 80 and 93 feet in well MW-6, 85 and 95 feet in well MW-7. The maximum concentration of DIPE detected in soil samples was 0.16 mg/kg (MW-5d85). During the site assessment activities, a septic leach pit was discovered within approximately 15 feet of well MW-4. Specific dimensions and historical use of the leach pit were not identified at the time of the assessment (KHM’s Additional Site Assessment Report, 2002).

Based on the historical soil analytical data, TPH-g impacted areas are in the vicinity of boring B-7 (south of the former USTs) and well MW-4 (south of the former dispenser islands) to the maximum depth of 50 ft bgs. The maximum TPH-g concentration from these borings is 6,700 mg/kg (MW-4d35). MTBE impacted areas were in the vicinity of well location MW-5 (west of the former dispenser islands) between depths of 40 and 90 bgs in the vicinity of the former USTs. The maximum MTBE concentration from this boring is 0.22 mg/kg (MW-5d75).

Soil analytical data from previous investigations are provided in Tables 2 through 4. Cross-section maps are provided as Figures 3 through 5. April 22, 2010 1650 Artesia Blvd., Redondo Beach, California Closure Request / Remedial Action Plan Page 9

HYDROCARBON DISTRIBUTION IN GROUNDWATER

PEG’s Subsurface Investigation, dated September 23, 1999, detailed the results of grab groundwater samples collected from borings B-5, B-6, B-7, and B-11. TPH-g, BTEX compounds, and MTBE were detected in the grab groundwater samples collected from B-5, B-6, and B-7. Maximum concentrations of TPH-g, benzene, and MTBE were reported in the grab sample collected from boring B-5 at 3,400 µg/L, 18 µg/L, and 220 µg/, respectively. Maximum concentrations of toluene, ethylbenzene, and total xylenes were reported in the grab sample collected from boring B-7 at 46 µg/L, 76 µg/L, and 260 µg/L, respectively.

Four additional grab groundwater samples were collected during the 2002 site assessment conducted at the site. TPH-g was detected in all grab groundwater samples, with the exception of GW-MW-8, with concentrations ranging from 250 µg/L (GW-MW-7) to 11,000 µg/L (GW-MW-6). Benzene was detected in one grab groundwater sample (GW-MW-6) at a concentration of 49 µg/L. MTBE was detected in all grab groundwater samples, with the exception of GW-MW-4, with concentrations ranging from 22 µg/L (GW-MW-7) to 4,400 µg/L (GW-MW-6). TBA was detected in three of the five samples with concentrations ranging from 37 µg/L (GW-MW-4) to 570 µg/L (GW-MW-6), and DIPE was detected in all five samples with concentrations ranging from 3.9 µg/L (GW- MW-8) to 250 µg/L (GW-MW-5) (KHM’s Additional Site Assessment Report, 2002).

As part of the quarterly groundwater monitoring program, eight monitoring wells (MW-1 through MW-8) were sampled from December 2000 to November 2009. Historical groundwater sampling indicated separate phase hydrocarbons (SPH) were not encountered in the wells sampled. Maximum TPH-g, ethylbenzene, MTBE, TBA and DIPE concentrations were detected in well MW-6 with concentrations of 6,500 µg/L, 350 µg/L, 3,600 µg/L, 1,300 µg/L, and 360 µg/L, respectively. Maximum benzene, toluene and total xylenes concentrations were detected in well MW-2 with concentrations of 30 µg/L, 180 µg/L, and 238 µg/L, respectively. Wells MW-4 through MW-8 were abandoned in November 2004 and August 2006 due to site redevelopment.

During the most recent quarterly groundwater monitoring and sampling event conducted on November 23, 2009, three monitoring wells (MW-1 through MW-3) were sampled. SPH was not encountered in any of the wells. Maximum concentrations of TPH-g, MTBE, TBA, and DIPE were detected in well MW-3 at concentrations of 1,400 µg/L, 460 µg/L, 2,100 µg/L, and 60 µg/L, respectively. MTBE was also detected in well MW-2 with a concentration of 1.4 µg/L. Benzene, toluene, ethylbenzene, xylenes, ethyl tert butyl ether (ETBE), tert amyl methyl ether (TAME), and ethanol were not detected above the respective reporting limits during the fourth quarter 2009 sampling event. Table 5 presents a summary of the historical groundwater analytical data. Fourth Quarter 2009 groundwater maps are provided as Figures 6 and 7. Time series graphs of constituent of concern concentrations in groundwater and depth to groundwater vs. time are presented as Graphs 1 and 2.

WELL RECEPTOR INFORMATION

The nearest field-verified drinking water well was identified as State Well No. 03S/14W-30G01S (Well 14), located approximately 4,520 feet northwest of the site. However, according to research conducted by BBL Environmental Information (May 2005) on behalf of SHELL, this well has been taken out of service and destroyed; the well was owned by the City of Redondo Beach. Similarly, Well 13 (03S/14W-30H02S) is reportedly located approximately 3,900 feet north of the site but could not be field-verified. This well, also owned by the City of April 22, 2010 1650 Artesia Blvd., Redondo Beach, California Closure Request / Remedial Action Plan Page 10

Redondo Beach, has been taken out of service and destroyed. No other active wells (water supply or monitoring) were identified to be within a one-mile radius of the site (BBL, 2005).

SENSITIVE RECEPTORS

The site is located in a mixed residential and commercial area. The nearest school was found to be the Manhattan Beach Nursery School located approximately 1,590 feet northwest of the site. Mira Coast High School was identified as approximately 1,760 feet west of the site, and Beach Babies child care center was identified as approximately 2,250 feet west of the site. A marsh area was identified as being approximately 1,760 feet west of the site. The Pacific Ocean is located approximately 1.5 miles to the west of the site.

POTENTIAL EXPOSURE PATHWAYS AND APPLICABLE CLEANUP LEVELS

Based on known site conditions, there are no potentially complete exposure pathways for the subject site. Exposure pathways that were evaluated, but not considered complete include:

• Ingestion of Impacted Groundwater. Given the distance and direction from the site to production wells and surface water bodies, ingestion of impacted groundwater is not likely to occur.

• Ingestion of Soil and Dust. Ingestion of soil and dust is unlikely to occur because the site is covered with asphalt and concrete. The potential for soil/dust ingestion may exist during any future construction activities. Risk associated with these activities can be managed through implementation of a health and safety plan to include vapor and dust monitoring and control measures.

• Dermal Contact with Soils. Dermal contact with impacted soil is unlikely to occur because the site is covered with asphalt and concrete. The potential for soil/dust dermal contact may exist during any future construction activities. Risk associated with these activities can be managed through implementation of a health and safety plan to include vapor and dust monitoring and control measures.

• Vapor Intrusion. The potential for exposure to hydrocarbon vapors migrating through the building floor from impacted soil below the site is low due to the depths and concentrations of measured impacts.

To protect potential current and future beneficial use of groundwater in the vicinity, appropriate groundwater cleanup levels for the subject area were obtained. The maximum contaminants limits (MCLs) are presented in the table below and were obtained from Environmental Protection Agency (EPA) National Primary Drinking Water Regulations (EPA, 2003), California primary maximum contaminant level (CDPH, 2008) and California Department of Public Health-Drinking Water Program (CDPH, 2007): April 22, 2010 1650 Artesia Blvd., Redondo Beach, California Closure Request / Remedial Action Plan Page 11

Soil screening levels were developed to reduce the risk for residential occupants due to the potential for exposure to hydrocarbon vapors below the site. Appropriate soil screening levels were estimated from the table of maximum soil screening levels for the TPH, BTEX and MTBE above drinking water aquifers obtained from Regional Water Quality Control Board, Los Angeles Region (LARWQCB, Interim Site Assessment & Cleanup Guidebook, Table 4-1, 2006). These soil screening levels are presented in the table below:

REMEDIAL ACTION PLAN

In the following section, DELTA has reviewed the currently applicable remedial approaches for addressing the fuel hydrocarbon and oxygenate impacts identified beneath the site.

Evaluation of Alternatives

Each remedial action was reviewed for feasibility based on the technical potential of implementing the reviewed action, economic feasibility based on the cost to implement the reviewed action, and regulatory acceptance or feasibility of the reviewed action. These components are defined below:

• Technical Feasibility is based on the ease of implementation, availability of equipment and applicability of the technology to the site-specific parameters. Excellent technical feasibility means that the remedial action is easily implemented, with readily available equipment and applies directly to the constituents to be remediated. Poor feasibility means that equipment is not readily available, the process is difficult, or in the experimental stages of development.

• Economic Feasibility is rated on the basis of excellent, good, fair and poor. Excellent being low in cost and poor being extremely costly for implementation of the remedial action.

• Regulatory Feasibility is based on past experience of regulatory acceptance of the remedial method reviewed as it applies to the specific parameters of the site. An excellent rating means that it has had a high regulatory acceptance and is currently in use on similar sites. A poor regulatory rating means that the remedial method under review is unlikely to be accepted by regulators, is not currently being utilized on similar sites, or is not applicable to the parameters of the site.

The following remedial actions were evaluated for soil and/or groundwater remediation feasibility at the site:

• No Further Action;

• Natural Attenuation/Long Term Monitoring;

• Excavation;

• In-Situ Bioremediation;

• In-situ Chemical Oxidation Injection; and

• Short-Term Groundwater Extraction. April 22, 2010 1650 Artesia Blvd., Redondo Beach, California Closure Request / Remedial Action Plan Page 13

The following table summarizes remedial alternatives that were considered for this site, along with the level of technical, economic, and regulatory feasibility:

Remedial Technical Economic Regulatory Alternative Feasibility Feasibility Feasibility

No Further Action Excellent Excellent Good

Natural Attenuation / Excellent Good Excellent Long Term Monitoring

Excavation Poor Poor Poor

In-Situ Bioremediation Fair Fair Fair

In-situ Chemical Oxidation Poor Poor Fair Injection

Short-Term Groundwater Fair Fair Fair Extraction

Evaluation Results

No Further Action has excellent technical and economic feasibility as no further action is required. This option has good feasibility from a regulatory standpoint as concentrations of TPH-g, MTBE, TBA, and DIPE in the groundwater detected in well MW-3 are stable. Constituents of concern from the remaining on-site wells are not detected above analytical reporting limits or MCLs.

Natural Attenuation/Long Term Monitoring for groundwater remediation has excellent technical feasibility as quarterly groundwater monitoring is already being conducted at the site. The presence of TBA in groundwater samples suggests that natural attenuation is ongoing. Based on electronic communication with Ms. Mercedes Hsu of the LARWQCB (Appendix D), monitored natural attenuation is an option that was suggested, giving this option an excellent regulatory feasibility. This option would create minimal residential interference during monitoring and sampling events. This option has good economic feasibility.

Excavation has poor technical feasibility due to the existence of buildings, asphalt and concrete on site. This site is occupied by a two-story, eight-unit condominium complex with one level of underground parking. The excavation option does not directly address groundwater impacts, and therefore it has poor regulatory feasibility. Economically, the excavation option is infeasible due to costs associated with the excavation as well as the interruption costs. April 22, 2010 1650 Artesia Blvd., Redondo Beach, California Closure Request / Remedial Action Plan Page 14

In-Situ Bioremediation is low in cost when compared to a pump and treat system, giving it a fair economic feasibility. This option has fair technical feasibility due to the accessibility restriction at the site. Issues with the length of time to remediate give this option only a fair regulatory feasibility.

The In-situ Chemical Oxidation Injection would deliver specific amounts of an oxidizing agent to mix with the groundwater and increase the oxidation of TPH-g and MTBE. However, limitations due to site soils, site access and potential rebound of the dissolved concentrations make this option poor in technical feasibility. This option is also negatively impacted by restrictive access issues. The economic feasibility is poor when compared to natural attenuation, due to the installation of injection points and the cost of the oxidizing chemical. The regulatory feasibility is fair due to the active nature of the remediation.

Short-term groundwater extraction might assist with short-term containment and control of a plume. Pumping from existing wells could reduce the hydrocarbon concentrations in the extraction well. For these reasons this option has fair ratings for technical feasibility and regulatory feasibility. Short-term groundwater extraction eliminates the need of a groundwater extraction system and remediation compound, however, this option has only fair economic feasibility because the cost compared to the mass removed is high, and activities would encroach on the public right-of-way.

SUMMARY OF FINDINGS

Based on the above information, Delta presents the following summary of findings:

• All historical sources of release have been removed from the site. All service station structures, including four USTs, five dispensers, three hoists, a clarifier, and subsurface piping were removed from the site in February 1999. Following tank removal, TPH-g was detected in two of thirteen soil samples with a maximum concentration of 200 mg/kg; BTEX compounds were detected in one soil sample collected beneath the fuel USTs with a benzene concentration of 0.18 mg/kg, a toluene concentration of 1.4 mg/kg, an ethyl benzene concentration of 0.48 mg/kg, and a total xylenes concentration of 6.0 mg/kg. MTBE was detected in 11 samples with a maximum concentration of 20 mg/kg.

• Eleven soil borings drilled in August 1999 (B-1 through B-11) showed TPH-g and BTEX compounds were present in soils between the depths of 20 and 50 feet bgs near the southern portion of the former tank complex (B-5) and the adjacent fuel dispenser (B-7). The maximum TPH-g concentration reported was 6,100 mg/kg (45 feet bgs in boring B-7). MTBE was detected in four shallow soil samples (above 25 feet bgs) with a maximum reported concentration of 4.7 mg/kg (boring B-6).

• Soil samples collected during the installation of monitoring wells MW-1 through MW-8 showed that soils impacted by TPH-g were present from 15 to 85 feet bgs in the boring for well MW-4 which was reportedly drilled adjacent to a historic leach pit. Low concentrations of TPH-g, BTEX compounds, and fuel oxygenates were also identified in samples collected between 60 and 80 feet bgs from borings MW-2 through MW-6 in an area south of the former UST complex and north of MW-4. April 22, 2010 1650 Artesia Blvd., Redondo Beach, California Closure Request / Remedial Action Plan Page 15

• TPH-g, BTEX compounds, and fuel oxygenates were detected in grab groundwater samples collected and analyzed during the assessments conducted in August 1999 (borings B-1 through B-11), October 2000 (wells MW-1 through MW-3), and July 2002 (wells MW-4 through MW-8). The maximum concentrations of TPH-g, benzene, MTBE, and TBA were detected in the grab groundwater sample from well MW-6 (sample GW-MW-6) at 11,000 µg/L, 49 µg/L, 4,400 µg/L, and 570 µg/L, respectively.

• Routine groundwater monitoring activities were initiated in December 2000 with wells MW-1 through MW-3. Wells MW-4 through MW-8 were added to the program in September 2002. Wells MW-4 through MW-6 were abandoned in July 2004 in preparation of the site redevelopment, and wells MW-7 and MW-8 were abandoned in August 2006.

• Groundwater occurs at a depth of approximately 72.80 to 73.70 feet below top of well casing and the groundwater gradient measured during the fourth quarter 2009 monitoring event is easterly with a gradient of approximately 0.002 ft/ft.

• The results of the most recent groundwater sampling event from third quarter 2009 demonstrate TPH-g was detected in one groundwater sample collected from well MW-3 at a concentration of 1,400 μg/L. BTEX compounds were not detected above reporting limits in groundwater samples collected from all wells. MTBE was detected in groundwater samples collected from wells MW-2 and MW-3 at concentrations of 1.4 μg/L and 460 µg/L, respectively. TBA and DIPE were detected in one groundwater sample collected from well MW-3 at concentrations of 2,100 µg/L and 60 µg/L, respectively.

CONCLUSIONS

Based on the prior information, DELTA presents the following conclusions:

• The potential source of the petroleum hydrocarbon impact has been removed by removal of the underground storage tanks, dispensers, hoists, the clarifier, and all subgrade piping.

• Based on the assessments conducted at the site, the lateral and vertical extent of hydrocarbon impact in the subsurface soil has been defined.

• A review of groundwater data obtained over the past year (since September 2008), as presented in Graphs 1 and 2, demonstrates concentrations of TPH-g, BTEX compounds, and fuel oxygenates are stable.

• The presence of increased levels of TBA in well MW-3, as well as diminishing levels of dissolved oxygen (DO) in this well, suggests that bioremediation is occurring in groundwater.

• As this site has been completely redeveloped as a residential facility, no further on-site assessment can be accomplished, nor can on-site remediation be practically achieved here due to physical constraints.

• As the City of Redondo Beach will not allow encroachment in the public right-of-way, further off-site assessment cannot be accomplished.
