The site location is shown in Figure 1, below. The project has been designed to meet the requirements of the 2017 City of Renton Surface Water Design Manual (RSWDM). FIGURE 1 – Vicinity Map The existing, approximate 0.248-acre site is partially developed and is currently covered with existing vegetation. After construction is completed for this permit, the site will include a new residence, paved walkway, and paved driveway. The neighboring parcels contain single-family residences. Historic land cover characteristics are provided below in Table 1 Project Site 2 | P a g e TABLE 1 – PREDEVELOPED AREAS Description Area (ft2) Total (ft2) Impervious --- --- --- Pervious Existing Vegetation 10,798 10,798 Total 10,798 The developed site will consist of a new single-family residence with an estimated roof area of 2,381 square feet, an 1,881 square-foot driveway, 435 square-foot sidewalk with ramps, 352 square feet of newly expanded road, curb, gutter, 3,291 square feet of landscaping and 1,740 square feet of gravel for safe walking routes to the nearest intersections. The developed areas are tallied below in Table 2. The developed sub-basin map is included in Appendix B. The soils present on the project site are identified in the geotechnical report as Alderwood gravelly sandy loam soils (AgC). Stormwater runoff from the roof and driveway areas will be conveyed to the existing stormwater system in SE 164th Street.

The developed site will require an addition of 6,789 square feet of new impervious surface including the rooftop area, driveway, sidewalk, and frontage improvement. This project proposes 6,789 square of new impervious area and therefore, does not qualify for Simplified Drainage review. Directed Drainage Review per section 1.1.2.3 will be applied to this project. All nine Core Requirements and all six Special Requirements have been considered in this report, as follows: Core Requirement #1: Discharge at the Natural Location Under existing conditions stormwater runoff flows to the southwest corner of the property and enters a man-made network of ditches and culverts in SE 164th Street. Under developed 3 | P a g e conditions stormwater from the site will continue to be released into the existing ditch system from the areas that will not be infiltrated and from the on-site pervious pavement in the case of overflow. Core Requirement #2: Off-site Analysis The existing downstream system has been reviewed and a downstream map and system description is included in Appendix E. Core Requirement #3: Flow Control Facilities This project will be exempt from flow control requirements because there will be less than a 0.15 CFS increase in the 15-minute, 100-year peak flow rate. Core Requirement #4: Conveyance System All new conveyance pipes will be analyzed to show the following: 1. The conveyance system has sufficient capacity to convey and contain (at minimum) the 25- year peak flow, assuming developed conditions for on-site tributary areas and existing conditions for any off-site tributary areas. 2. The 100-year peak flow to the existing system will not create or aggravate a “severe flooding problem” or “severe erosion problem” as defined in Core Requirement #2 and that any overflow occurring on-site for runoff events up to and including the 100-year event discharges at the natural location for the project site. Core Requirement #5: Erosion and Sediment Control Erosion and sedimentation control will be designed per Appendix D of the RSWDM. Core Requirement #6: Maintenance and Operations An operation and maintenance manual will be included in the final TIR and will provide the necessary guidance for operating and maintaining the on-site stormwater system. Core Requirement #7: Financial Guarantees and Liability A bond quantities worksheet is included in this TIR. Core Requirement #8: Water Quality Facilities The project will be exempt from the requirement to provide basic water quality treatment since less than 5,000 square feet of new or replaced pollution-generating impervious surface (PGIS) is proposed. Core Requirement #9: On-site BMPs BMPs will be applied as described in the Small Lot BMPs section of this TIR. 4 | P a g e Special Requirement #1: Other Adopted Area-Specific Requirements There are no known area-specific special requirements that apply to this project site. Special Requirement #2: Flood Hazard Area Delineations There are no known flood hazard areas on or adjacent to this project. Special Requirement #3: Flood Protection Facilities Flood protection facility special requirements do not apply to this project. The project does not propose to construct a new or modify an existing flood protection facility. Special Requirement #4: Source Controls Since the proposed project is a single family residence, source control measures are not anticipated to be required in conjunction with this project. There is no proposed outside-use or storage of pollutants. Special Requirement #5: Oil Control The proposed project does not require oil control measurements. The site is not considered high- use since it is a single family residence. 3.0 OFF-SITE ANALYSIS The runoff from the site enters a ditch near the southwest corner of the property. The ditch flows to the west along the north side of SE 164th Street and conveys the water through a series of culverts and ditches for approximately 474 feet. The conveyance network is described in the following table starting from the southwest corner of the property: TABLE 3 – DOWNSTREAM CONVEYANCE Type Length (ft) 1 Ditch 98 2 Culvert 19 3 Ditch 22 4 Culvert 19 5 Ditch 61 6 Culvert 24 7 Ditch 32 8 Culvert 156 9 Ditch 29 10 Culvert 14 11 Stream 846 5 | P a g e At the end of the ditch and culvert system the rain water is directed to the north through a catch basin into a stream. The stream begins on parcel 008800031 and continues due north onto parcel 008800030 for about 846 feet to a point past a quarter mile downstream of the project site. 4.0 FLOW CONTROL AND WATER QUALITY FACILITY ANALYSIS AND DESIGN Flow Control A WWHM analysis of the historic and developed surfaces has been completed and included in this report. This analysis shows that the 15-minute, 100-year peak flow rate under historic conditions (moderately-sloped forest on type B & C soils) from the area that will be disturbed by this project will not be surpassed by the 100-year peak flow rate under developed conditions by more than 0.15 cfs. This project will, therefore, exempt from providing flow control facilities. Permeable pavement flow control BMPs from Appendix C of the RSWDM will be applied and the credits from Table 1.2.9.A of the RSWDM were applied to the analysis. Under developed conditions, the portion of the property that will be disturbed for construction will be covered by 2,381 square feet of roof (0.055 acres), 2,914 square feet of driveway (0.074 acres), 435 square feet of sidewalk (0.010) and 4,777 square feet of lawn and landscaping (0.110 acres). The on-site driveway will be fully mitigated by paving it with permeable pavement and, therefore, will be modeled as 50% impervious and 50% grass. The area of driveway used in the model includes 50% of on-site driveway, 100% of off-site driveway and off-site impervious. The run-on from the roof does not receive a credit. Impervious area for the model includes 0.074 acres of driveway, 0.055 acres of roof and 0.010 acres of sidewalk. The table below summarizes the inputs to the WWHM model for this project. WWHM MODEL SUMMARY Developed Modeled as Impervious Lawn Pasture Forest Impervious 0.156 acres 0.138 acres 0.018 acres 0.000 acres 0.000 acres Landscaping 0.092 acres 0.000 acres 0.092 acres 0.000 acres 0.000 acres Totals 0.248 acres 0.138 acres 0.110 acres 0.000 acres 0.000acres The results of the model for developed conditions indicate that the 15-minute, 100-year peak flow will be 0.195 cfs. This is less than a 0.15 cfs increase over the 15-minute, the 100-year peak for 0.248 acres of moderately sloping forest on type C soils (0.001 cfs) and this project is, therefore, exempt from providing additional flow control facilities. Detailed calculations are included in Appendix E. BMPs Section C.1.3.1 of the City of Renton Surface Water Design Manual applies to projects on lots smaller than 22,000 square feet and thus the following requirements of this section apply: 6 | P a g e Small Lot BMP Requirements: Mitigation of Impervious Surface: The proposed project is on a site/lot smaller than 22,000 square feet, therefore, flow control BMPs must be applied as specified in Appendix C, Section C.1.3.1 or the project must comply with the LID performance standard. It is infeasible to use full dispersion BMPs as detailed in Appendix C, Section C.2.1.1 because of limited space available on the property. The native vegetative flow path for full dispersion is required be at least 100 feet in length and is not available on the project site. Full infiltration BMP as detailed in Appendix C, Section C.2.2 is not feasible for the same reasons that limited infiltration BMPs are infeasible, listed in this section. It is infeasible to use limited infiltration BMPs as detailed in Appendix C, Section C.2.3 due to space limitations. Per Appendix C, Section C.2.2.2 #3 a minimum 5-foot setback is required for any part of the infiltration device and property lines. Additionally, per Appendix C, Section C.2.2.3 point #7 and Section C.2.2.4 point #6 all infiltrative devices are required to maintain a 15-foot setback from buildings with crawl space or basement with elevations that are below the overflow point of the infiltration system. Therefore, as a result of the applicant proposing a house with a crawl space under the fished floor grade, full infiltration and limited infiltration BMPs are infeasible. Rain garden BMP as detailed in Appendix C. Section 2.12 is infeasible due to the lack of available space. Similarly, Bioretention BMP as detailed on Appendix C, Section C.2.6 is not feasible because limited space on site doesn’t allow for the required storage volume. The geotechnical report provided by JECB indicates that permeable pavement, as detailed in Appendix C, Section C.2.7 of the RSWDM is feasible for this property and, therefore, all 1,535 square feet of the driveway will be constructed of permeable pavement with a 6-inch sand layer beneath the pavement to treat the stormwater runoff and to reduce the risk of ground water contamination. Per the geotechnical engineer’s recommendation, the design shall include 12 to 24 inches of clean rock under the permeable pavement to replace the compacted existing soils. The measured infiltration rate was indicated to be 24.5 inches per hour in the report provided by JECB. Applying a testing factor of 0.3 to account for the EPA falling head method that was used to measure the infiltration rate, a geometry factor of 1.0 to account for what is expected to be at least 4 feet of separation between an impermeable layer and the bottom of the facility and a width of 15 feet, and a plugging factor of 0.7 for sandy loam soils, results in a design infiltration rate of 5.15 inches per hour. Run-on on the permeable pavement is limited to a maximum of 5 times the permeable pavement area. Therefore, the entire 2,381 square feet of roof impervious area will be directed to run-on onto the permeable pavement. Per Appendix C, Section C.2.7, runoff directed to permeable pavement is considered to have met the minimum on-site BMP implementation requirements. To satisfy the overflow requirement, slotted drain pipe will be installed along the property line on the south side of the shared driveway to route flow to the stormwater conveyance system in 164th. This will be accomplished by connecting the slotted drain pipe to catch basin at southwest corner of the shared driveway. 7 | P a g e The WWHM analysis of the permeable pavement indicates that 100% of the runoff from the roof and the driveway (0.09 acres) will be infiltrated. Detailed calculations are included in Appendix E. Water Quality This project is exempt from providing water quality treatment because there will be less than 5,000 square feet of PGIS. 5.0 CONVEYANCE SYSTEM ANALYSIS AND DESIGN Conveyance pipes for the roof will consist of a typical gutter system, splash blocks or similar downspout outlets, and/or 6-inch PVC pipe at a minimum slope of 1% that will adequately convey all of the runoff from the roof to the point of discharge. A new storm system will be installed along the gutter line to replace the existing culvert that conveyed stormwater along the ditch. The system will consist of 12-inch SDR-35 pipes and 28 lineal feet of 16-inch DIP at the most downstream section of the network. A separate on-site network will convey stormwater from an existing 8-inch pipe through a 12-inch SDR-35 pipe network into the public conveyance system. A backwater analysis was performed for the combined network using the Autodesk Hydroflow Storm Sewers Extension software. The incoming flows were approximated using a WWHM model with a 15-minute timestep. The upstream basins and their covers were approximated from the King County iMap application. The upstream basin map can be reviewed in Appendix E. The basin collected by the on-site pipe system (Basin A) has a 25-year peak flow rate of 1.51 cfs and a 100-year peak flow rate of 2.12 cfs, both based on the WWHM model. The basin collected by the right of way culvert replacement has a 25-year peak flow rate of 3.76 cfs and a 100-year peak flow rate of 5.07 cfs, also based on the WWHM model. The results of the backwater analysis indicate that the 25-year peak flow is fully contained in the pipes and the 100-year is fully contained in the pipes and catch basins of the system. For more in-depth reports, please refer to Appendix E for the WWHM report and the backwater analysis. 6.0 SPECIAL REPORTS AND STUDIES A geotechnical report has been included in Appendix A of this TIR. No additional special reports or studies are required for this proposed project. 7.0 OTHER PERMITS A building permit for the proposed house on Lot 2 will be required for this project. 8.0 ESC ANALYSIS AND DESIGN Erosion and sediment control requirements will include the delineation of clearing limits via flagging, proper cover measures for the protection of disturbed areas, perimeter protection with 8 | P a g e silt fencing on an as-needed basis, and a stabilized construction entrance per City of Renton standards. The Erosion and Sediment Control Plan has been included as part of the construction plans and is included in Appendix C. 9.0 BOND QUANTITIES, FACILITY SUMMARIES, AND DECLARATION OF COVENANT A bond quantities worksheet is attached in Appendix E. 10.0 OPERATIONS AND MAINTENANCE MANUAL The operations and maintenance details for the private facilities are provided in the Operations and Maintenance Manual found in Appendix D.
