STATEMENT OF UNDERSTANDING:
The AS team understands that the City of Hermosa Beach (City) intents to implement the Hermosa Beach Greenbelt Infiltration project (Project) to demonstrate compliance based on the goals of the Beach Cities Enhanced Watershed Management Program (EWMP) that was developed in response to the requirements of the 2012 Municipal Separate Storm Sewer System (MS4) Permit. The selected project site is a greenbelt area on Valley Drive between 2nd Street and Herondo Street and is part of the 3.5-mile-long Hermosa Valley Green Belt Trail. The site was once a railroad right of way, is now an active recreational trail used by joggers, walkers, and strollers. This Project is identified as the highest priority project and represents the most important and cost effective of three new regional BMPs proposed in the EWMP. The Project is the first of its kind that is undertaken by the City and will be developed in accordance to the 10% project concept (as provided in Appendix 2 of the RFP) and the supporting site geotechnical study that was previously performed. In accordance with the 10% project concept, components of the underground flow diversion and infiltration system will consist of the following:
• A diversion structure to redirect dry and wet-weather flows (up to Qdmax or 47 cfs) from the Herondo Street storm drain system (21” RCP) to an underground infiltration system. A flow meter at the diversion pipe to measure the volume of water diverted. • A gross solids removal device (GSRD) system for full trash capture of the flows prior to discharge into the forebay. • A forebay (30’ x 150’) to impound, infiltrate and controlled release of flows. The forebay will be designed to accommodate low-flow/dry-weather infiltration. Wet-weather overflow within the forebay will be released via a notched weir to an infiltration gallery. • An infiltration gallery (600’ x 150’) to accept wet-weather overflow from the forebay where additional infiltration will occur.
Additional project benefits and considerations include the following:
• Reducing downstream flooding through diverted flows from the Herondo Street storm drain to the underground forebay and infiltration gallery system that affords storage capacity. • Preserving the existing linear greenbelt as a running path. • Restoring the native coastal dune habitat. • Engineered surface/fill to support loads associated with municipal vehicles for parkland maintenance.
The Project is partially funded by the State Water Resource Control Board’s (SWRCB) Proposition 1, Storm Water Grant Program, Implementation Round 1 and will comply with the requirements and terms and conditions of the executed grant agreement between the California State Water Resource Control Board and the City of Hermosa Beach for the design and construction of the project. Matching funds is from the Beach Cities Watershed Management Group that includes the cities of Hermosa Beach, Manhattan Beach, Redondo Beach, Torrance and Los Angeles County Flood Control District (LACFCD).
The AS team will consider all aspects of the project and provide creative design solutions that would satisfy project objectives and constraints as it relates to design, operations and maintenance of the facility. The culmination of work would result in the preparation and delivery of plans, specifications and cost estimate to allow for construction bidding and award.
City of Hermosa Beach Greenbelt Infiltration Project 7 TECHNICAL APPROACH:
The AS team has developed a technical approach for the project to effectively streamline the design process that promotes time and cost savings. Tasks associated with the technical approach for all disciplines are reflected on the Project Schedule provided within this section of the Proposal, in accordance to the RFP. The culmination of required task by the various AS team disciplines are consolidated into the Scope of Work developed for the Project as follows:
A. PROJECT MANAGEMENT AND ADMINISTRATION
1. Project Coordination:
The AS team through the primary point of contact will coordinate the project with City staff, agencies, utilities, and other entities as needed during the design development and plan preparation process.
2. Project Progress Meetings:
The AS team will conduct progress meetings with the City during the course of the project. A minimum of four (4) progress meetings are anticipated to be held for project kick-off, the Preliminary Design Report and following the review of plans for the 60% and 90% stages of plan completion. Additional meetings that may potentially be needed, as determined during the course of the project will be scheduled on an “as-needed” basis and includes the following:
• Meeting(s) with affected utility agencies for the relocation of facilities (as applicable). • Meeting(s) with City staff (and stakeholders as applicable) on items related to the public outreach effort, budgeting/grant funding, and other items if requested.
3. Project Submittals:
The AS team will provide the PDR as the 30% level of completion submittal for the project. Plans will be prepared and submitted at the 60% and 100% stages of completion once a preferred final alternative is selected for implementation by the City. The Plans, Specifications and Estimates (PS&E) documents will be provided in printed and electronic format in accordance with City requirements.
4. Project Schedule:
AS will provide a project schedule (in MS Project format) on project initiation to the City and will revise and maintain the schedule throughout the course of the project, as necessary. The City will be provided with an updated project schedule whenever a revision to the schedule is made.
B. PRELIMINARY DESIGN PHASE
1. Research and Site Investigation:
Obtain available record drawings from the City, utility providers, and other applicable agencies for existing infrastructure information within or adjacent to the site. Conduct a preliminary site investigation with key team members to ascertain field conditions, identify site constraints and other factors necessary for a successful design.
City of Hermosa Beach Greenbelt Infiltration Project 8 2. Utility Notifications and Investigation:
A “Project Notification and Request for Information” letter will be initially sent to utility providers. All information received will be compiled and reviewed for potential conflicts with proposed work. A “Notice to Relocate” letter with the 60% completion level plans will be sent to utility providers identifying potential utility conflicts that may need to be verified and addressed. AS will continuously coordinate with affected utility providers (and City staff) for timing, verification and potential relocation of their facilities for a suitable outcome. Finally, a “Prepare to Relocate” letter with final plans will be sent to utility providers that will provide notification of imminent work to begin. Provisions for ground penetration radar and potholing are provided under optional items, if required.
3. Topographic Survey and Base Map:
Obtain available records from the City and other applicable agencies for boundary information within or adjacent to the site. Provide a topography survey for the subject property, identifying approximate property lines based upon record information. Obtain existing topography data, providing spot elevations and contours at a level of accuracy sufficient for development of construction documents and prepare a base map for use as the basis for design. Title reports are assumed not to be required and therefore are not included.
4. Preliminary Drainage and Facility Design Assessment:
Review technical/design documents to assess the existing drainage condition of the Herondo Street storm drain system and verify the design criteria and parameters for the proposed forebay and infiltration gallery, as provided by the Hermosa Greenbelt Subsurface Infiltration Facility Conceptual Design (10% Design) in Appendix 2 of the RFP. Documents for review includes the approved EWMP, Infiltration Testing and Preliminary Geotechnical Investigation report for the greenbelt project, related Hydrology & Hydraulics Report/Study for the stipulated 2,914-acre tributary area serviced by the Herondo Street storm drain system and other related documentation/calculations that was used in the development of the 10% design concept, as applicable. Data and conclusions derived from the preliminary assessment will be used for the development of alternatives that will be presented in the Preliminary Design Report.
5. Supplemental Geotechnical Investigation:
In addition to the Infiltration Testing and Preliminary Geotechnical Investigation recently prepared by the City’s consultant, a supplemental geotechnical investigation may be needed to ascertain recommendations to support the construction of site improvements for the greenbelt area. Since site improvements corresponding to surface and subsurface facilities are yet to be determined, a budgeted amount for potential supplemental geotechnical services is included in the fee proposal for this purpose.
6. Preliminary Design Report (PDR):
The AS team will prepare a PDR as part of the design development process that includes three (3) alternatives for the subsurface storm water infiltration system that is proposed within the greenbelt area based on the preliminary drainage and facility design assessment. Development of alternatives for subsurface facilities along with associated design elements and details will include, but is not limited to the following:
City of Hermosa Beach Greenbelt Infiltration Project 9 • Flow diversion, treatment methods and systems for full trash capture. • “Custom-designed” and “pre-fabricated” storage and infiltration solutions. • Long-term storage for potential reuse of diverted flows for irrigation purposes. • Facility access and maintenance.
Surface restoration of the existing greenbelt area is a large part of this Project and will be considered within the PDR. Based upon the information received during the kickoff meeting with the design team and data collected during the site reconnaissance, preliminary design concepts will be formulated. Three (3) alternative for surface improvements will be developed with illustrative elevations/cross sections in plan-view format. These will illustrate elements such as general landscape character, thematic possibilities and recreational features. They will include both soft scape and hardscape elements. The alternatives may include the following design considerations as they fit with the engineering design for the site as follows:
• Removal of the “ice plant” (Carpobrotus spp.) via appropriate methodology (physical, biological and/or chemical). The site is situated approximately 1,500 feet from the surf line, protected from ocean winds and is comprised mostly of the “ice plant” which is an invasive and non-native plant material. While this plant historically was used to help stabilize slopes, it has been found that its detrimental effects far outweigh its benefits. One detrimental character is that it prevents native species from propagating and it also creates a suitable environment for disease carrying rodents to nest. • Landscape design utilizing low water-use plant palette best suited for coastal climate. • Development of bio-swales and other infiltration features. • Prevention of grade disturbance of natural soil around existing mature trees which will remain protected in place with drip line irrigation. • Reintroduction of beach sand in strategic areas to restore site to a coastal dunes habitat. • Drip and subsurface irrigation redesign for compliance with AB 1881 and MWELO. • Potential relocation of underground utilities within the project site. • Opportunity to delineate the trail between pedestrians and municipal vehicles by use of base materials. • Related educational opportunities for the public via educational signage. Other signage may include way finding, mile markers, etc. • Themed site amenities such as benches, trash receptacles, doggie-bag stations and other park related amenities for trail users are not recommended for this site but can be implemented if desired by the City.
Preliminary cost estimates for the overall three (3) alternatives broken down by design items/elements, along with a recommendation for a preferred alternative will be provided in the report. The PDR will provide sufficient information/details of the proposed alternatives that can be utilized for review by the Public Works Commission and/or City Council, if needed.
7. California Environmental Quality Act (CEQA) Review:
The proposed project is funded in part by the State Water Resource Control Board’s (SWRCB) Proposition 1, Storm Water Grant Program - Implementation Round 1, with matching funds from the Beach Cities Watershed Management Group. As such, state environmental documentation will be required to satisfy the California Environmental Quality Act (CEQA). The CEQA Lead Agency for this project will be the City of Hermosa Beach. CEQA documentation will consist of an Initial Study/ Mitigated Negative Declaration (IS/MND) with the following tasks:
City of Hermosa Beach Greenbelt Infiltration Project 10 • Administrative Draft IS/MND:
An IS will be prepared using the approved checklist format from the City or Appendix G of the CEQA Guidelines. A project description will be prepared to include the location of the project area (including a project map), a brief description of the environmental setting, an identification of environmental effects using the above-referenced checklist format, a brief substantiation of the checklist entries, and a list of references and preparers. Mitigation measures will be provided (if required) that can be developed using existing data. A site visit by an Environmental Scientist will be conducted. In addition, record/database searches for biological, cultural, and paleontological resources will be conducted. We have assumed we will receive copies of any previously-prepared technical reports, plans, and other project information from the City, including electronic versions, to the extent possible. Five (5) bound copies of the Administrative Draft IS/MND will be submitted to the City for review and comment.
• Prepare Draft IS/MND:
After receipt of one (1) set of integrated comments on the Administrative Draft IS/MND from the City, we will revise the IS/MND accordingly. ECORP will provide five (5) bound copies, one (1) unbound, reproducible copy, and one (1) electronic copy of the environmental document to the City for internal use. ECORP will mail twenty (20) copies of the document to addressees on the mailing list and fifteen (15) copies to the State Clearinghouse. We have assumed that the City and ECORP will work together to assemble the mailing list.
• Prepare Public and Agency Notices:
The following notices will be prepared, as required by CEQA: 1. Notice of Intent (NOI) to Adopt a Mitigated Negative Declaration 2. Notice of Completion (State Clearinghouse Cover) 3. Notice of Determination (NOD)
One copy of each of these notices will be filed with the Los Angeles County Clerk and the State Clearinghouse, as appropriate. One electronic copy of each notice will be provided to the City. It has been assumed that the City will pay any fees associated with these notices, and will arrange for the NOI to be published in a newspaper of general circulation.
• Final IS/MND and MMRP:
The Lead Agency (City) must consider any comments received on the MND when making a decision on the project. There is no requirement to prepare formal responses to comments; however, the Lead Agency should have information in the administrative record explaining why the comment does not affect the findings in the MND. For costing purposes, we have assumed that 5 comment letters containing 2 comments each will be received (or a total of 10 comments). In practice, a response to comments document, which is included in the Final IS/MND, is usually prepared. The Final IS/MND will also include any changes to the Draft IS/MND and the Mitigation Monitoring and Reporting Plan (MMRP, if required), prepared in accordance with CEQA Guidelines Section 15097. The MMRP will be prepared in a table format with input from the City.
An Administrative Final IS/MND and MMRP will be prepared. After review by the City, the Final IS/MND and MMRP will be provided. We will send the Final IS/MND and MMRP to agencies, organizations, and individuals that commented on the project, and also notify them of the date and time of the public hearing for consideration of the project, as required by CEQA. City of Hermosa Beach Greenbelt Infiltration Project 11 Deliverables will include the following: • Five (5) copies of the Administrative Final IS/MND and MMRP • Five (5) bound copies and one (1) electronic copy of the Final IS/MND • Five (5) bound copies will be mailed to commenting agencies and interested parties, for a total of 10 bound copies

Project specifications (inclusive of all disciplines) will be provided as part final construction document submittal to the City.
10. Monitoring Plan and QAPP (Optional Item)
The Herondo Storm Drain Greenbelt Infiltration Project directly supports the City of Hermosa Beach’s (City) implementation of adaptive management strategies to protect downstream water contact recreational activities at the beach and implementation of the BMP provides a critical load reduction strategy for under the Santa Monica Bay Beaches Bacteria TMDL for eliminating storm- event based runoff on a year-round basis. Should this task be needed, it will be performed by Amec Foster Wheeler (AMEC) who is exceptionally familiar with storm-event monitoring and understands the practical aspects of sampling and flow monitoring of wet weather runoff for structural BMPs (best management practices) such as infiltration galleries and has extensive experience with helping public agencies implement monitoring for indicator bacteria load reduction projects under a wide range of conditions. AMEC has direct experience with the monitoring methods required for assessing the performance of the Greenbelt Infiltration BMP. AMEC has conducted functionally identical monitoring and most recently completed the second year of three pilot projects for the California Department of Transportation District 11 office as part of the metals, pesticides, and bacteria TMDL programs for the Chollas Creek Watershed. AMEC’s experience with monitoring infiltration gallery type of structural BMPs means that they understand the challenges with these types of treatment systems, have the requisite experience needed to implement adaptive techniques for a wide range of challenging site conditions, and that our experience can ultimately help the City demonstrate that the proposed EWMP load reduction strategy is effective.
Services for the Greenbelt Infiltration BMP project will focus on preparation of a State Water Resources Control Board approved Monitoring Plan and QAPP. The Monitoring Plan and QAPP development process would include suggestions for recommended monitoring locations, methods, sampling frequencies (if required), and data management practices for hydrologic and meteorological datasets. The monitoring approach to evaluate the BMP effectiveness will follow the Wet Weather criteria as specified in the Beach Cities Watershed Management Group Coordinated Integrated Monitoring Program (Section 2.3.2).
For water quality monitoring protocols, the proposed monitoring locations for this project would include four (4) types of sites to assess performance of the implemented BMP implementation. The primary focuses of the monitoring program would include the following proposed sites:
• Flow monitoring locations to recorded runoff volumes diverted into the forebay, infiltration gallery, and flows routed around the diversion structure.
City of Hermosa Beach Greenbelt Infiltration Project 14 • Rainfall monitoring locations to record local and watershed specific precipitation totals. The rainfall measurements would focus on adapted existing monitoring locations, as listed in Table 1, with addition gages included on an as-needed basis. • Water level measurements to record stored volumes contained within the forebay and infiltration gallery. • Water quality measurements at the diversion structure and additional key monitoring locations to characterize indicator bacteria loads, and other parameters of concern, during different storm events covering a range of storm sizes up to the 90th percentile event.
This project will leverage existing rainfall monitoring efforts performed by Los Angeles County (LAC), the National Oceanic and Atmospheric Administration (NOAA), and Weather Underground to provide the data needed for the rainfall-runoff modeling and flow weighted compositing sampling elements. The existing rain gages listed in Table 1 that may provide data for this project take into local differences in elevation and the potential of isolated storm cells within the sub-watershed drainage area.

The monitoring plan will be designed to collect the following sets of information from the existing storm drain system during wet weather conditions that represents a range of predicted rain fall amounts and potentially up to the 90th percentile storm event. Our implementation approach for water quality monitoring focuses on four elements which are; • Continuous flow monitoring in the storm drain system using an area-velocity sensor with data logged at 1 minute (wet weather) and 15 minute (dry weather) intervals. • Continuous water level monitoring in the forebay and infiltration galleries using a pressure- transducer based sensor with data logged at 1 minute (wet weather) and 15 minute (dry weather) intervals. • Adopting datasets from external rainfall monitoring programs for the rainfall-runoff calculations. • If required, water quality sample analyses using constant-time or constant-discharge volume protocols for indicator bacteria parameters as defined in the Beach Cities Watershed Management Group Coordinated Integrated Monitoring Plan, Appendix E.
AMEC’s monitoring support for the City would try to leverage any existing datasets as part of the load reduction assessment in order to maintain consistency with the historical datasets. For data management protocols, the data management requirements for this project include standardized data
City of Hermosa Beach Greenbelt Infiltration Project 15 formats that are accepted by the California Environmental Data Exchange Network (CEDEN) and the stormwater monitoring data protocols prepared by the California Department of Transportation in the Stormwater Monitoring Guidance Manual.

The proposed project aims to restore the pre-development hydrologic conditions by constructing various LID BMPs within the site. Specifically, these BMPs will provide the opportunity for OCPW to analyze and provide the information to the public on various BMPs and their application on filtration, infiltration, evapotranspiration, retention and storage facilities. The Glassell Yard Campus Stormwater Retrofit Project is integrated with the planned driveway and parking lot improvements. The project includes the construction of permeable pavement (concrete, asphalt, and decorative pavers); flow-through biotreatment planter boxes; cartridge media filters; vegetated bioswales; an underground detention basin; and an above-ground cistern. University Hills - Agave Park Client: Irvine Campus Housing Authority Victor Van Zandt - VP Planning/ Construction P:949.824.4827 [email protected]
Situated in the University Hills of the University of California in Irvine’s faculty housing neighborhood; this “Agave” park joins Planning Area 9-2 and 9-4. The vertical grade differential between the two planning areas was roughly 7’. The park incorporated a series of steps to connect these two planning areas together along with incorporating a meandering ADA compliant walkway made of decomposed granite. The ramps were well integrated into the design using ledgestone covered seat walls to soften up the aesthetic look of unappealing manufactured slopes. The geometry of the land between the two planning areas allowed for the design to take advantage of typically unusable areas to incorporate charming secluded seating spaces with views to Newport Coast. The park design incorporated agave plants, various succulents, and other drought tolerant plant material to reduce irrigation and has been a model for other parks at University Hills. Skyridge Stormwater Improvement Project Client: CalAtlantic Homes Cyrstal Burckle - Director of Development P:949.789.1723 [email protected]
This 84 lot, 28 acres residential development project is in a hillside setting along northerly boundaries of the City of Mission Viejo.

City of Hermosa Beach Greenbelt Infiltration Project 20 Section 7 Quality Control/Quality Assurance
The AS team is committed to providing the best possible service and product from project inception to completion. Unlike programs that employ a separate process for QA/QC that is typically initiated after significant work has been completed, AS defaults to a process whereby QA/QC is continuously practiced as part of the design development and plan preparation process. This practice consists of a peer “checks and balances” procedure that is conducted regularly between senior staff members (typically the Project Director and Project Manager) and key sub-consultant(s) to ensure appropriate concepts and detailed designs are derived and implemented for the project, in consideration of constructibility and cost considerations. Milestone checks and continuous coordination between senior and production staff members during the plan preparation process are performed to ensure proper work quality of deliverables are achieved and maintained. This streamlined method of integrating QA/QC within the design process also results in better control of the budget and project schedule. The practice typically considers the review of following items:
• Concept & Scope Development • Environmental Compliance • Design Details and PS&E Preparation • Constructibility and Cost Considerations (Value Engineering) • Conformity to CAD/Drafting Standards • Fulfilling City Related Requirements, Comments and Considerations • Completeness and Quality of Deliverables
