(CEKO) has been contracted by Magellan Architects, project architect, to provide civil engineering design and consulting services in support of the proposed preschool playground improvements at 4110 Northeast 4th Street in Renton, Washington (herein referred to as the Site). The proposed improvements are to be constructed on an approximately 6,700-square-foot portion of a single parcel, consisting of King County Parcel No. 1023059128. The total parcel area encompasses approximately 3.56 acres of land. A Site location map is provided on Figure 1. It is anticipated that project construction will be completed in a single phase, with commencement of construction activities in 2023 and completion by the winter of 2023. This Technical Information Report (TIR) has been prepared to fulfill City of Renton Land Use and Building Permit application submittal requirements. This TIR includes descriptions and documentation demonstrating how the proposed project design will comply with the requirements set forth by the City of Renton in the adopted City of Renton Surface Water Design Manual, adopted on June 22, 2022 (RSWDM 2022), and the 2021 King County Surface Water Design Manual dated September 25, 2019 (KCSWDM 2021). A TIR worksheet is provided as Figures 2A through 2E in the building permit submittal issue of this report. It is anticipated that a Targeted Drainage Review, per Figures 3A through 3C (RSWDM 2022 Figure 1.1.2.A), is triggered for this project. 1.1 EXISTING SITE CONDITIONS AND HYDROLOGY The project Site area is approximately 6,700 square feet in the highlands of the City of Renton, Washington, and is currently developed as a grass area that is part of an existing commercial shopping center. The Site parcel is bordered as follows: · To the north by multi-family residential; · To the east and south, by other parcels of the same commercial shopping center, and the NE 4th Street right-of-way; and · To the west by commercial and multi-family commercial properties, and the Union Ave., NE right-of-way. See Figure 4 for a depiction of existing conditions. As reported by City of Renton staff, the Site is within the Black River Drainage Basin. Currently, the Site is served by an existing on-Site stormwater collection and management system constructed with the development of the commercial shopping center. Based on a review of information presented on COR MAPS, which is the City of Renton online GIS map system, stormwater runoff flows from the Site and the commercial shopping center are conveyed south via public surface water mains to a discharge to Maplewood Creek, near its headwater, just south of the NE 4th Street right-of-way. Maplewood Creek conveys flows southward to a confluence CEKO 1-2 C:\CEKO\Projects\Active\22015.01-Magellan-Goddard-Renton\Engineering\TIR\Goddard-Renton-TIR-2022-10-06.docx CEKO, LLC ■ 425-864-8246 ■ 2255 Squak Mountain Loop SW ■ Issaquah, Washington 98027 ■ www.cekonw.com with the Cedar River, near Maplewood Golf Course and Maple Valley Highway, also known as State Route 169. Based on a review of the USDA NRCS Web Soil Survey, the Site is underlain with Alderwood gravelly sandy loam with 8 percent to 15 percent slopes, abbreviated as AgC. AgC is considered a low permeability, till-like soil. See Figures 5A through 5E. Based on a review of date presented on the Federal Emergency Management Agency (FEMA) online Flood Insurance Rate Map (FIRM), Map No. 53033C0981G, the Site is an area designated as Zone X, which is defined as an area of minimal flood hazard. There are no known flood control facilities on or associated with the Site. See Figure 6. 1.2 PROPOSED SITE CONDITIONS AND HYDROLOGY The proposed project includes construction of the following improvements: · Tenant improvements, interior to the existing building; · Modifications to an existing loading dock; · Construction of a new preschool playground conforming to the standards of the Goddard School; · Construction of associated stormwater management facilities; and · Construction of additional and/or modified landscaping, where required. The new playground area is located on the north end of the existing on-Site building, in an area that is currently vegetated with mowed grass. See Figure 7 for a depiction of proposed developed conditions. The Site is in an area of the City of Renton which is required to meet the Peak Rate Flow Control Standard, which means that the site stormwater management system is required to match peak flow rates of the existing Site conditions for the 2-year, 10-year, and 100-year 24-hour design storm events (RSWDM 2022 1.2.3.1). The proposed stormwater management system for the Site will include detention in the void volume of the base rock beneath the proposed play area pervious surfaces. This approach is often used for synthetic turf athletic field projects and is desirable because of co-location of the flow control stormwater facility beneath the proposed play area and because the facility allows for partial infiltration within a substantial portion of the play area footprint. The proposed improvement surface areas are all non-pollution generating; therefore, no water quality facilities are proposed.

The project is subject to the City of Renton Stormwater Standards, which, at the time of project vesting, follow the adopted RSWDM 2022 and KCSWDM 2021. These requirements are as described Section 2.2, Adopted Basin Plans. 2.2 ADOPTED BASIN PLANS The project is located within the City of Renton and in the Black River Drainage Basin. Other than the requirements defined by RSWDM 2022, no additional basin plan requirements are in effect. 2.3 STATE ENVIRONMENTAL POLICY ACT REVIEW AND MITIGATION The project size is below thresholds that would trigger review and mitigation under the Washington State Environmental Policy Act (SEPA). SEPA review is not required. 2.4 CORE REQUIREMENTS As described in Table 1.1.2.A of RSWDM 2022, and with the assumption that the project will be subject to Targeted Drainage Review, the project is anticipated to be required to meet the nine Core Drainage Requirements listed below. The six Special Drainage Requirements are not anticipated to be applicable to the project. 2.4.1 DISCHARGE AT NATURAL LOCATION The proposed improvements will not alter the discharge location for the Site. 2.4.2 OFF-SITE ANALYSIS A limited analysis of off-Site downstream drainage conditions has been completed in support of this preliminary report. Additional analyses can be completed if and as required and appropriate, after preliminary review by City of Renton staff of the proposed improvements. 2.4.3 FLOW CONTROL FACILITIES Flow control facilities are proposed, and are anticipated to include detention in the void volume of the base rock beneath the proposed play area pervious surfaces, limited infiltration within the footprint of the proposed play areas, and a flow control structure prior to discharge from the proposed detention system.

Easements and/or Declarations of Covenants will also be prepared and submitted if and as required. 2.4.8 WATER QUALITY FACILITIES The proposed improvements are entirely non-pollution generating surface. Because of this, the requirement to include water quality facilities is not applicable. No water quality facilities are proposed. 2.4.9 ON-SITE BEST MANAGEMENT PRACTICES (BMPs) The proposed detention system will allow for limited include limited infiltration within the footprint of the proposed play areas, thereby meeting this requirement.

Maplewood Creek conveys flows southward to a confluence with the Cedar River, near Maplewood Golf Course and Maple Valley Highway, also known as State Route 169. Additional offsite analyses, including a field review of the downstream flow path can be performed if and as required and appropriate, after preliminary review by City of Renton staff of the proposed improvements.

The proposed TESC measures include: 1. Silt fences, aligned along the downhill perimeter of work areas; 2. Catch basin inserts, also known as inlet protection, placed in existing catch basins in the project area; 3. Straw wattles, placed where applicable around the existing, paved driveway area that will serve as the project staging area. The existing pavement, the straw wattles, and the relatively long paved driveway route to the street are intended to provide the protections normally addressed with a stabilized construction entrance; and 4. Temporary security fences, installed around construction areas, if and as needed to provide site security.
