Applicable water quality source controls will be applied in accordance with the King County Pollution Prevention Manual and Renton Municipal Code, Title IV. A designated area for refuse and recycling located on the south end of the building. 2.6 Special Requirement #5: Oil Control This requirement does not apply because the project is not expected to have more than 15,000 vehicles per day. 2.7 Special Requirement #6: Aquifer Protection Area This requirement does not apply because the project is not located within an aquifer protection area. Core Design, Inc. Parking Lot Expansion Swanson Gardner Meyers Page 6 3 OFFSITE ANALYSIS TASK 1 Study Area Definition and Maps The proposed project contains parcel number 3123059069. A map of the downstream can be found in Figure 3-1 Downstream Drainage Exhibit. TASK 2 Resource Review Basin Reconnaissance Summary Reports: No Basin Reconnaissance Summary Reports appear to be available for the area that is within one mile of this project site. FEMA Maps: Per the City’s Effective FEMA Flood Insurance Rate Map, the project site is not in the 100-year floodplain. The FEMA Map is included in Appendix B. Sensitive Areas Folio: Per the City of Renton Sensitive Areas Maps, this project not located in any sensitive areas. Soils The Geotechnical Report was completed by Nelson Geotechnical Associates, Inc. dated January 3, 2019. The following was encountered at each test pit “approximately 0.8 to 3.0 feet of loose to medium dense, silty sand with varying amounts of roots, gravel, organics, which [was] interpreted as undocumented fill soils. Underlying fill soils [was] orange-brown to gray-brown, relatively granular silty fine to medium sand with varying amounts of gravel and iron-oxide staining, which [was] interpreted as native ground marine deposits type soils.” Downstream Drainage Complaints Drainage complaints were researched within the study area. There were no drainage complaints downstream of the site within a quarter mile. See the Drainage Complaint Exhibit in Appendix B. Restrictive Well Covenant There is no existing well onsite. TASK 3 Field Investigation Upstream Tributary Area There is minimal upstream drainage area from fully vegetated parcel to the east that has plans for development in which all of their storm water will be captured and detained. Core Design, Inc. Parking Lot Expansion Swanson Gardner Meyers Page 7 Downstream Analysis The site drains west to the 12-inch storm drain system in Talbot Road that drains north for about 690 feet until S 43rd Street where it heads west for 550 feet and north for 150 feet through the parking lot of Valley Medical Center. The storm system in Valley Medical Center drains around the south and west sides of the property for about 1,200 feet before discharging into an open channel flowing north to Panther Creek. 4,514752 Figure 3-1 Downstream Drainage This map is a user generated static output from an Internet mapping site and is for reference only.

Parking Lot Expansion Swanson Gardner Meyers Page 12 4 FLOW CONTROL AND WATER QUALITY DESIGN 4.1 Predeveloped Site Hydrology The total parcel area is 27,644 square feet or 0.63 acres however, the disturbed area is only 8,380 square feet which will be considered as the project area. The existing building, parking lot, and portion of the rockery on the east property line are not included in the project area since they will remain and not be disturbed. All of the trees are on the south side of existing building and the site drains to the west at an average grade of 6 percent. There is no upstream drainage area from the developed neighboring parcel as all stormwater is detained and treated on site. The predeveloped conditions are shown in Table 4-1 below and Figure 4-1 Existing Conditions. Table 4-1 Predeveloped Condition Areas Land Use Area (sf) Area (ac) Till-Forest 8,380 0.19 4.2 Developed Site Hydrology In the developed condition, a new parking lot will be constructed, extending the existing parking lot further south. Landscaping will also be applied throughout the site around the parking lot and building. Proposed utility work includes new catch basins to capture runoff from the proposed parking lot and direct it to the existing system located in Talbot Road S. The splash block installed with the office addition will be connected to the storm drain system. Therefore, a new downspout and splash block on the north end of the site will be installed. See Table 4-2 below and Figure 4-2 Developed Conditions. Table 4-2 Developed Conditions Areas Land Use Area (sf) Area (ac) Till-Grass 4,514 0.10 Impervious 3,866 0.09 New Parking Lot 3,866 0.09 Total 8,380 0.19 Core Design, Inc. Parking Lot Expansion Swanson Gardner Meyers Page 13 4.3 Performance Standards Flow Control Duration Standard (Forested Condition) The facility requirement in the Flow Control Duration Standard Matching Forested Site Conditions is waived for any threshold discharge area in which there is no more than a 0.15 cfs difference (when modeling using 15-min time steps) between the 100-year developed conditions and 100-year predeveloped or historical site conditions. The predeveloped and developed site conditions were modeled in WWHM and the results are shown below: Therefore, the difference between the 100-year developed peak flow and the 100-year predeveloped peak flow is 0.10 cfs – 0.02 cfs or 0.08 cfs and the project is exempt from flow control. Water Quality: Basic Water Quality Menu This project will add only 3,427 square feet of pollution generating hard surface, which is less than 5,000 square feet so no water quality treatment is required.

Parking Lot Expansion Swanson Gardner Meyers Page 16 4.4 BMP Analysis Large Lot BMP Requirements If the proposed project is on a site/lot larger than 22,000 square feet, then flow control BMPs must be applied as specified in the requirements below or the project must demonstrate compliance with the LID Performance Standard (described in Section 1.2.9.1.B, p. 1-83) using an approved continuous runoff model. This project is not in compliance with the LID performance standard and has evaluated the following BMPs in order of precedence: 1. Full Dispersion – A native flowpath of 100 feet and no steeper than 20% per the requirements of Appendix C, Section C2.1.1 cannot be met so full dispersion is infeasible. 2. Full Infiltration of Roof Runoff – Per the Geotech report the subsurface soils consisted of silty fine to medium sand with gravel that was interpreted to be ground marine deposits and existing soils must be coarse sands, cobbles, or medium sands. 3. All target surfaces not mitigated by requirements 1 and 2 above, must be mitigated to the maximum extent feasible using one or more of the BMPs from the following list: • Full Infiltration has been considered infeasible per number two above. Limited Infiltration has been considered infeasible because the existing soils need to be fine sands, loamy sands, sandy loams or loams and the onsite soils consist of silty fine to medium sand with gravel. • Bioretention and Permeable Pavement is infeasible per the geotechnical findings. An underdrain would need to be installed and either LID technique would not quality as a flow control BMP. 4. All target surfaces not mitigated by requirements 1, 2 and 3 above, must be mitigated to the maximum extent feasible using basic dispersion. Basic dispersion is feasible and will be proposed via splash blocks. 5. BMPs must be implemented, at a minimum for an impervious area defined as follows: For projects that will result in an impervious surface coverage 45-65% on the buildable portion of the site/lot, on-site BMPs must be applied to 50% of target impervious surfaces reduced by 1.5% for each 1% of impervious surface coverage above 45% (e.g., impervious coverage of 55% results in a requirement of on-site BMPs applied to 35% of target impervious surfaces). 46% Core Design, Inc. Parking Lot Expansion Swanson Gardner Meyers Page 17 This project will result in 46% impervious area so the project must provide the following onsite BMPs: 46% - 45% = 1% 1 * 1.5 = 1.5 Therefore, BMPs are required for 50% – 1.5% = 48.5% Target Impervious Surface = Parking Lot = 3,866 sf Required BMPs = 3,866 sf x 0.485 = 1,875 sf Due to site constraints, the project is unable to provide BMPs to the maximum extend feasible. • Reduced Impervious Surface Credit – This project does not qualify for a reduced impervious surface credit. • Native Grown Protection Credit – This project does not qualify for a native growth protection credit. 6. The soil moisture capacity of new pervious surfaces must be protected in accordance with the City’s standards. The soil moisture capacity of the developed pervious surfaces will be protected per the City’s standards. 7. Any proposed connection of roof downspouts to the local drainage system must be via a perforated pipe connection. There are no proposed connection of roof downspouts to the local drainage system in this project because the perforated pipe connection would have to be under the proposed parking lot. Small Road Improvement and Urban Road Improvement Projects BMP Requirements If the proposed project is a road improvement project that is within the UGA or is on a site/parcel less than five acres in size, then flow control BMPs must be applied as specified in Section 1.2.9.3 however there are no road improvements associated with this project so the road improvement BMP requirements do not apply. Core Design, Inc. Parking Lot Expansion Swanson Gardner Meyers Page 18 5 CONVEYANCE SYSTEM ANALYSIS AND DESIGN The 6-inch pipe that connects into the existing SDMH #7003 has a 1.8% slope (n=0.012) and per Manning’s equation has a capacity of 0.8155 cfs. The pipe needs to be able to convey runoff from the proposed parking lot and area from the roof that used to disperse via the splash block, but will now connect to the storm system. The areas are 3,866 SF from the parking lot and perforated pipe connection and 700 SF from the splash block area. The total area is 4,566 SF of impervious. Below are the flows from 4,566 SF of impervious area. The flow rate for the 100-year storm is less than the max capacity of the 6” pipe. Therefore, the existing 6” pipe has the capacity to convey all the proposed runoff. Core Design, Inc.
