C. Power and water supply are in the vicinity of the site but are limited. There is a hose bib and electrical panel on the restroom building located approximately 150 feet northeast of the site. The building is white with a blue roof and can be seen in the aerial on Sheet L- 3. Power and water is likely not sufficient for a job trailer or other large usage, but is available for minor power and water needs. If larger quantities of water are required, the contractor can obtain a fire hydrant meter from the City of Bartlesville, however the closest hydrant is on the south side of Adams Boulevard that lies adjacent to the south side of the Lee Lake Park site. A deposit is required for the hydrant meter that will be reimbursed upon return of the meter. Water used in association with this project is free of charge. If additional power needs are required, the contractor shall be responsible for coordinating temporary construction site power with AEP/PSO.

June 15, 2018 Kleinfelder Project No.: 20190806.001A

Mr. Micah Siemers, P.E. City of Bartlesville, Oklahoma 401 South Johnstone Avenue Bartlesville, Oklahoma 74003 E-mail: [email protected]

Subject: Subsurface Exploration and Laboratory Test Results Proposed Bartlesville Skate Park Bartlesville, Oklahoma

Dear Mr. Siemers:

In accordance with your request, Kleinfelder has completed the authorized subsurface exploration and laboratory testing for the above referenced project. It is our understanding that City of Bartlesville is planning to build a Stake Park south of the Bartlesville Soccer Field and west of Cooper Dog Park at northeast corner of SE Adams Boulevard and Silver Lake Road. No plan has been provided to Kleinfelder at time of this report. However, it is expected that the Stake Park will have a footprint of approximately 100 feet by 100 feet.

Kleinfelder was retained to perform two soil test borings and subsequent laboratory testing for the soil samples. Geotechnical engineering recommendations for the proposed Skate Park were not requested and therefore were not included in our scope of work. Kleinfelder conducted the field work by drilling two borings on June 11, 2018 at locations shown on Figure 1, Boring Location Plan and Vicinity Map. A hand-held GPS unit was used to locate the explorations with an accuracy of 15 feet or less. The general site location is shown on top right corner of Figure 1, Boring Location Plan and Vicinity Map.

The borings were advanced using a 4-inch diameter hand auger to approximately 5 feet below existing ground surface. The samples were sealed and returned to our laboratory for future examination, classification, and testing. The borings were backfilled in accordance with the appropriate Oklahoma Water Resources Board Regulations.

Laboratory tests including sieve analyses, Atterberg limits, and moisture contents were performed on four of the samples for classification purposes in general accordance with applicable standards. The results of the tests are presented on the respective boring logs and in attached Laboratory Test Results Summary Sheet.

Groundwater observations were made during and at completion of our drilling operations, and no groundwater seepage was observed. Field logs included visual classification of the materials encountered during drilling, as well as drilling characteristics. Our final boring logs represent the engineer’s interpretation of the field logs combined with laboratory observation and testing of the

20190806.001A / TUL18L79922 Page 1 of 2 June 15, 2018 © 2018 Kleinfelder www.kleinfelder.com Interchange Business Park, 10835 East Independence, Suite 102, Tulsa, OK 74116-5680 p| 918.627.6161 f| 918.627.6262

samples. Stratification boundaries indicated on the boring logs were based on observations during our field work, an extrapolation of information obtained by examining samples from the borings, and comparisons of soils with similar engineering characteristics. Locations of these boundaries are approximate, and the transitions between material types may be gradual rather than clearly defined. Boring logs are attached.

Boring B-1 and B-2 consisted of primarily fat clay to the termination depth of the borings, which is 5 feet below existing ground surface. The plastic limit of the fat clay ranged from 56 to 70 while the plasticity index ranged from 32 to 44.

Clay soils that have a moderate to high shrink-swell potential were encountered in both of the borings. Depending upon the design grades, these materials could be exposed at the finish subgrade level. Undercutting or stabilization of these soils should be anticipated. Typical remedial measures include treating the material with hydrated lime, cement kiln dust (CKD) or Class C fly ash in accordance with ODOT Method OHD L-50. A mix design is beyond the scope of this project. However, Kleinfelder can assist during the construction phase of the project if required.

We recommend that all structural fill placed required to achieve design grades consist of approved materials, free of organic matter and debris. All structural fill placed within the pavement area should consist of lower plasticity soil with a maximum Plasticity Index (PI) of 18 as determined by the Atterberg Limits test ASTM D 4318. In areas where high plasticity clay is present at design subgrade elevation, undercutting is recommended to allow placement of a minimum of 8 inches of low plasticity structural fill below the pavement section.

Information presented in this letter is based on our field observations, subsurface explorations, and limited laboratory tests. It is possible that subsurface conditions could vary between or beyond the points explored. We appreciate the opportunity to be of service to you on this project. Please call us if you have any questions concerning the information presented within this letter.

Sincerely, KLEINFELDER, INC. Certificate of Authorization #7292, Expires 6/30/19

Subsurface problems are a principal cause of construction delays, cost overruns, claims, and disputes.

While you cannot eliminate all such risks, you can manage them. The following information is provided to help.

The Geoprofessional Business Association (GBA) Typical changes that could erode the reliability of this report include has prepared this advisory to help you – assumedly those that affect: a client representative – interpret and apply this • the site’s size or shape; geotechnical-engineering report as effectively • the function of the proposed structure, as when it’s as possible. In that way, clients can benefit from changed from a parking garage to an office building, or from a light-industrial plant to a refrigerated warehouse; a lowered exposure to the subsurface problems • the elevation, configuration, location, orientation, or that, for decades, have been a principal cause of weight of the proposed structure; construction delays, cost overruns, claims, and • the composition of the design team; or disputes.

No one except authorized client representatives should rely on this geotechnical-engineering report without first Note, too, that it could be unwise to rely on a geotechnical-engineering conferring with the geotechnical engineer who prepared it. And no one report whose reliability may have been affected by the passage of time, – not even you – should apply this report for any purpose or project except because of factors like changed subsurface conditions; new or modified the one originally contemplated. codes, standards, or regulations; or new techniques or tools.
