Our Priority. | farallonconsulting.com June 27, 2022 Clark Close, Senior Planner City of Renton 1055 South Grady Way Renton, Washington 98057 RE: REQUEST FOR PERMIT MODIFICATION UPPER BALCH PIT SPECIAL GRADE/FILL PERMIT (LUA-18-000703) 301 MONROE AVENUE NORTHEAST RENTON, WASHINGTON FARALLON PN: 841-008 Dear Clark Close: Farallon Consulting, L.L.C. (Farallon) has prepared this letter on behalf of Segale Properties LLC to support its request for a permit modification to the Special Grade/Fill Permit Number LUA-18-000703 (Grade/Fill Permit) for the property at 301 Monroe Avenue Northeast in Renton, Washington (Upper Balch Pit). Specifically, this letter includes additional information requested by the City of Renton (City) to further support the proposed modification of the Grade/Fill Permit to exclude the requirement for completion of the City’s Fill Source Statement. An initial request for the permit modification was submitted to the City in the letter regarding Upper Balch Pit Special Grade/Fill Permit (LUA-18-000703), Request for Permit Modification dated April 21, 2022, from Jamie Schroeder of CPH Consultants to Clark Close of City of Renton (April 2022 Request Letter) and is attached for reference (Attachment A). This letter includes a summary of Farallon’s review and evaluation of the following main documents: • City of Renton, Water System Plan Update, A Comprehensive Water System Plan, December 2012 (2012 Plan); and • City of Renton, Water System Plan Update, Final May 2021 (2021 Plan). The purpose of the review was to evaluate the delineation of the City’s Aquifer Protection Areas (APAs) at the Upper Balch Pit property in the 2012 Plan versus the updated 2021 Plan, and to provide conclusions and recommendations regarding the potential exclusion of the Fill Source Statement requirement from the Grade/Fill Permit.

Our Priority. | farallonconsulting.com WATER SYSTEM PLANS 2012 WATER SYSTEM PLAN In the 2012 Plan, the Upper Balch Pit property was included within APA Zone 2 as shown on Figure 2-3 (2012 Plan, Appendix L). However, it should be noted that the Upper Balch Pit property was outside of the modeled 10-Year Capture Zone for the Downtown Wellfield Capture Zones (2012 Plan, Appendix L, Figure 2-3). 2021 WATER SYSTEM PLAN According to the 2021 Plan, the APAs were updated to be consistent with the modeled Wellhead Protection Area Capture Zones (WHPAs), which include 6-Month, 1-Year, 5-Year, and 10-Year Capture Zones as shown on Figure 1 (2021 Plan, Appendix J). The Upper Balch Pit property is outside of the 10-Year Capture Zone (2021 Plan, Appendix J, Figure 1). In addition, the updated 2021 Plan included an assessment of parcels of possible elevated risk within the WHPAs in the City, including the Downtown WHPA. The Upper Balch Pit was/is not included as a parcel with possible elevated risk (2021 Plan, Appendix J, Figure 3). The updated 2021 Plan also included an evaluation of potential contaminant sources in the City WHPAs. No confirmed or potential contaminant sources were identified at the Upper Balch Pit property (2021 Plan, Appendix J, Figure 5). CONCLUSIONS AND RECOMMENDATIONS These data confirm that the Upper Balch Pit property is outside of the 10-year Capture Zone for the Downtown WHPA and has not been identified as a parcel with possible elevated risk and/or potential contaminant source, which is consistent with the historical and current land use. Further, Segale Properties LLC plans to continue with requiring compliance with the Segale Fill Acceptance Standards and completion of a Segale Fill Source Statement prior to acceptance of fill material from future source sites as described in Exhibits B and C of the April 2022 Request Letter, respectively (Attachment A). Based on these data, Farallon, on behalf of Segale Properties LLC, requests that the City update the Grade/Fill Permit to exclude the requirement for a Fill Source Statement for the upper Balch Property.

Balch Pit Special Grade/Fill Permit (LUA-18-000703) Request for Permit Modification Mr. Close, Our client, Segale Properties LLC, is requesting a permit modification to remove the requirement for a Fill Source Statement by a professional engineer or geologist for the Upper Balch Pit Special Grade/Fill permit. The site is located at 301 Monroe Ave NE and the permit was approved with the Hearing Examiner’s final decision dated March 29, 2019 and the Determination of Non-significance-Mitigated (DNS-M) and Environmental Review Committee Report dated February 18, 2019 (City Land Use File Nos. LUA18-000703, ECF, SP). Condition no. 2 of the SEPA mitigation measures requires a Fill Source Statement to mitigate for adverse impacts to the aquifer protection zone. The request to remove the requirement is based on the fact that the project site is no longer delineated within a Wellhead Protection zone per current City of Renton critical area mapping as shown on the COR Maps website. The pit site was mapped within the Maplewood Wellhead Protection area at the time of the original permit approval. Since that time, further studies by others have determined that the Upper Balch Pit site is actually outside of wellhead and aquifer protection area. As such, a Fill Source Statement CERTIFIED BY A PROFESSIONAL ENGINEER OR GEOLOGIST should no longer by applicable for the site and the permit. The project will continue to meet requirements for clean fill sources; however, a certified statement would no longer be required. The following documents are provided for your reference: · Exhibit A – Original fill source statement (to be replaced with Exhibits B and C below) · Exhibit B – Proposed Fill Acceptance Standards · Exhibit C – Proposed Fill Source Statement Please contact me directly at (425) 285-2392 or by e-mail at jamie@cphconsultants.com if you have questions or need any additional information to complete your approval of this request. Thank you. Sincerely, CPH Consultants Jamie B. Schroeder, PE Vice President Enclosures: Exhibits A, B, and C Cc: Mike Pruitt, Segale Properties DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT 1 H/CED/Data/Forms-Templates/Self Help Handouts/Pubic Works/Fill Source Statement.doc Rev: 08/2015 A Fill Source Statement CERTIFIED BY A PROFESSIONAL ENGINEER OR GEOLOGIST licensed in the State of Washington is required in the following circumstances: 1.More than 50 cubic yards of fill will be imported to a project site located in Zone 1 of the Aquifer Protection Area. 2.More than 100 cubic yards of fill will be imported to a project site located in Zone 2 of the Aquifer Protection Area. Exception: A Fill Source Statement is not required if documentation is provided that the fill to be imported comes from a Washington State Department of Transportation approved source. It is required that fill material be sampled AT THE FILL SOURCE SITE and analyzed by a laboratory to rule out contamination (see #11 below). A fill source site may qualify for an ABBREVIATED FILL SOURCE STATEMENT (answer only #1 - #7 below) ONLY if the source site has never been filled, developed, or subjected to use that could have introduced chemical contamination to the site. The abbreviated format does not require sampling and analysis of fill to detect contamination and, therefore, reduces applicant costs. Please see #12 and check the appropriate certification. A SEPARATE SOURCE STATEMENT IS REQUIRED FOR EACH FILL SOURCE SITE. A copy of the Renton Municipal Code section requiring the Fill Source Statement is attached for your information (RMC 4-4-060N). CONTACT DEVELOPMENT ENGINEERING TO DETERMINE IF THE PROJECT SITE IS LOCATED IN THE APA. NOTE: The Department has the authority to request additional information regarding imported fill material and to reject a source statement if it does not demonstrate that the fill material meets City standards and/or the Department has reason to suspect that the fill material could be contaminated. Such requests or rejections shall be made in writing to the applicant. 1.Project Site Address: 2.Project Site King County Tax Assessor Account Number: 3.In which Aquifer Protection Area Zone is the project site located 1 or 2? 1 2 4.Cubic yards of fill to be imported to project site: 5.Project applicant name: 6.Fill source site address: 7.Fill source site King County Tax Assessor Account Number: FILL SOURCE STATEMENT FOR PROJECTS IN THE AQUIFER PROTECTION AREA (APA) Planning Division | Development Engineering Section 1055 South Grady Way | Renton, WA 98057 (425) 430-7200 | www.rentonwa.gov 2 H/CED/Data/Forms-Templates/Self Help Handouts/Pubic Works/Fill Source Statement.doc Rev: 08/2015 8.
