DocuSign Envelope ID: 44E7B13B-E61D-42E2-9010-CB07930C65F3 4 1.0 PROJECT OVERVIEW Existing Site: The site is located at 1833 NE 12th Street, Renton, Washington. The parcel number is 3119900160. The existing property is rectangular in shape, approximately 0.94 acres. The east ¼ of the parcel has been developed (single -family residence) and has slopes between 10 percent and 15 percent to the southwest. The house has been demolished; a driveway, lawn and landscaping remain. The west ¾ of the parcel is undeveloped, has slopes between 25 percent and 50 percent to the southwest, and ground cover consists of trees, brush, and grass. The site is bordered by NE 12th Street to the north, Puget Sound Energy property to the west, and a single-family property to the south and east. Refer to Appendix A, Figure 2 Site Location Map. Refer to Appendix A, Figure 3 Drainage Basin Map. The existing and proposed discharge flow paths from the site are shown on Figure 2. The existing discharge leaves the site and flows in a southwesterly direction. The flow is conveyed downhill in a heavily vegetated ravine and appears to discharge to a public 12- inch storm drain pipe (ID 702896). The pipe conveys flow to a Type 2 manhole (ID 133077). Flow continues in a series of public 36-inch storm drain pipes along the north side of NE Sunset Boulevard and enters a Type 2 catch b asin (ID 133079). The length of travel from the site to the Type 2 catch basin is approximately 370 feet. Developed Site: The proposal is to divide the eastern third of the property into three individual lots. The remainder of the parcel west of the three proposed lots has steep slopes and will remain undeveloped. A 15-foot set back and 15-foot buffer is proposed between the three proposed lots and the steep slopes. The proposed development will include frontage improvements, and sewer and domestic water services. A joint use driveway is proposed for Lots 1 and 2, and a separate driveway is proposed for Lot 3. The proposed discharge is conveyed to on-site detention pipes and control structure. Flow continues in storm drain pipes and is discharged to an existing swale 30 feet downstream of the site. Flow is conyeyed downhill to the west in the existing swale and is discharged to a depressed area. Flow from the depressed area drains to a public 36 - inch storm drain pipe (ID 119239). The pipe conveys f low to the previously discussed Type 2 catch basin (ID 133079). The length of travel from the site to the Type 2 catch basin is approximately 330 feet. DocuSign Envelope ID: 44E7B13B-E61D-42E2-9010-CB07930C65F3 5 Soils: According to Natural Resources Conservation Service data, the soil type for eastern portion of the parcel that is proposed to be developed is primarily Type InC, Indianola loamy sand, 5 to 15 percent slopes. According to NRCS, the soil type for the western portion of the parcel that is not proposed to be developed is primarily Type AkF, Alderwood and Kitsap soils, very steep. Refer to Appendix A, Figure 4 Soils Maps. According to the soils reports included in Appendix E, undocumented fill containing some debris and having relative densities ranging from very loose to medium dense was encountered to a depth of about 12 feet below ground surface. The fill was un derlain by medium dense to very dense natural sands and very dense silt soils. 2.0 CONDITIONS AND REQUIREMENTS SUMMARY Stormwater design shall be in accordance with the 2017 City of Renton Surface Water Design Manual. The site areas are described below. Refer to Appendix A, Figure 5 Developed Site Plan. Impervious Areas Roofs = 4,500 sf Driveways = 1,324 sf Total new/replaced impervious surface = 5,824 sf Pervious Areas Landscaping, Lawn = 11,493 sf Offsite Area Draining to Site 2,252 sf Total pervious area = 13,745 sf Total site area = 19,569 sf Lot 3 Area Draining Offsite (pervious)= 24,264 sf Figure 1.1.2.A “Flow Chart for Determining Type of Drainage Review Required” is used to determine requirements based on the following new/replaced hard surface areas. This is a single-family residential project that results in: DocuSign Envelope ID: 44E7B13B-E61D-42E2-9010-CB07930C65F3 6 • Greater than 2,000 sf of new and replaced impervious surface? Yes • Less than 5,000 sf of new plus replaced PGIS? Yes • Less than ¾ acre of pollution generating pervious surfaces? Yes AND does the project meet one of the following criteria: • For projects on predominately till soils: o The project results in < 7,947 sf of target impervious surfaces? Yes. The target impervious surface area is 5,824 sf. o AND, the proposed pervious surface is <14,941 – (1.88 X total target impervious surfaces)? No. 1.88 X 5,824 sf = 10,949 sf. 14,941 – 10,949 sf = 3,992 sf. The proposed pervious area is 11,493 sf, which exceeds this threshold. Although the last criteria was not met, a majority of the criteria has been met and the project is viewed as qualifying for Simplified Drainage Review. Per Figure 1.1.2.A, does the project contain or is adjacent to a flood, erosion, or steep slope hazard area? Yes. Refer to Appendix A, Figure 6. The project site is within and/or adjacent to an erosion hazard area. The project qualifies for Targeted Drainage Review . Reference is made to Table 1.1.2.A, Requirements Applied Under Each Drainage Review Type. The project is within and/or adjacent to an erosion hazard area. The project qualifies for a Category 1, Target Drainage Review. Core Requirement #1: Discharge at Natural Location Refer to Appendix A, Figure 2 Drainage Basin Map. The existing and proposed discharge flow paths from the site are shown on Appendix A, Figure 2. The existing discharge leaves the site and flows in a southwesterly direction. The flow is conveyed downhill in a heavily vegetated ravine and appears to discharge to a public 12 - inch storm drain pipe (ID 702896). The pipe conveys flow to a Type 2 manhole (ID 133077). Flow continues in a series of public 36-inch storm drain pipes along the north side of NE Sunset Boulevard and enters a Type 2 catch basin (ID 133079). The length of travel from the site to the Type 2 catch basin is approximately 370 feet. The proposed discharge is conveyed to on-site detention pipes and control structure. Flow continues in storm drain pipes and is discharged to an existing swale 30 feet downstream of the site. Flow is conveyed downhill to the west in the existing swale and DocuSign Envelope ID: 44E7B13B-E61D-42E2-9010-CB07930C65F3 7 is discharged to a depressed area. Flow from the depressed area drains to a public 36- inch storm drain pipe (ID 119239). The pipe conveys flow to the previously discussed Type 2 catch basin (ID 133079). The length of travel from the site to the Type 2 catch basin is approximately 330 feet. The proposed discharge path converges within ¼ mile of the natural discharge path. Core Requirement #2: Offsite Analysis 1. Define and Map the Study Area The study area includes the area downstream of the project site for the entire flow path for a minimum flow path distance of ¼ mile. 2. Resource Review A resource review was conducted to determine any potential problems offsite of the project site. The following resources were used in gathering information for the offsite analysis. • City of Renton GIS maps • King County IMap Drainage Complaint maps 3. Field Inspection A downstream field inspection has not yet been conducted. A complete downstream field inspection will be conducted during design development. 4. Drainage System Description and Problem Descriptions Refer to Appendix A, Figure 3 Drainage Basin Map. As described previously, the proposed discharge from the project site will be conveyed to on -site detention pipes and a control structure, prior to discharge from the site. The proposed flow control will protect downstream properties from increases in peak, duration, and volume of runoff generated by the proposed development. Flow continues to an existing swale 30 feet downstream of the site. Rock outfall protection will be proposed at this discharge location to mitigate any erosion issues. Flow is conveyed downhill to the west in the existing swale and is discharged to the public storm drain system on the north side of NE Sunset Boulevard (approximately 330 downstream of the project site). At this location, the proposed discharge from the site converges with the natural drainage discharge path. Flow continues to the west in the public storm drain system for a distance of ¼ mile downstream from the project site. A majority of the project site is within a high erosion haza rd area. Refer to Appendix A, Figure 6 City of Renton Erosion Hazard Map. Project impact to erosion problems will be DocuSign Envelope ID: 44E7B13B-E61D-42E2-9010-CB07930C65F3 8 mitigated by tight-lining discharge from the site to a location away from the erosion hazard area. King County IMap data was reviewed to determine the existence of any potential drainage issues in the vicinity. Refer to Appendix A, Figure 7. Two drainage complaints were discovered. Both of the drainage complaints are located upstream of the project site and are not considered relevant. Core Requirement #3: Flow Control Facilities Refer to Appendix A, Figure 8 City of Renton Flow Control Application Map. The project site is located within the Peak Rate Flow Control Standard region. Runoff from the site will be conveyed to on-site detention pipes and control structure prior to discharge from the site. Refer to Appendix A, Figure 5 Developed Site Plan.

The scope of this limited geotechnical evaluation letter was based upon written authorization received via email on December 6, 2019, and in accordance with the conditions outlined in our Master Services Agreement with Abbey Road Group dated June 12, 2018. This limited geotechnical evaluation does not include any recommendations for the design or construction of structures or land improvements. Our services were exclusively for evaluation of infiltration feasibility for the site. Introduction We understand that the project will consist of subdivision of the existing property into three (3) building lots. We have been requested to evaluate available subsurface and site information and to provide our opinion and recommendations regarding stormwater infiltration feasibility. For our evaluation of infiltration feasibility, we have reviewed the report titled “Subsurface Exploration and Limited Geotechnical Engineering Services – Proposed Rankin Short Plat”, prepared by Bergquist Engineering Services (BES), dated October 17, 2017, and the undated, untitled site plan drawing prepared by Pittman Engineering, as well as local geologic resources. General Project and Site Description The project site is located at 1833 NE 12th Street in Renton, Washington. We understand that the proposed development will consist of the construction of residential dwellings on an approximately 0.95-acre parcel of land. The site is bounded by NE 12th Street to the north, residential properties to the south and east, and undeveloped land and Interstate 405 to the west. Lot 1 and Lot 2 slope down towards the southwest at gradients of about 10 to 15 percent. Lot 3 slopes down at a gradient of about 13 percent from elevation 243 feet at the northeast corner of this lot to elevation DocuSign Envelope ID: 44E7B13B-E61D-42E2-9010-CB07930C65F3 KA Project No. 062-19020 Proposed Short Plat Infiltration Feasibility Evaluation December 23, 2019 Page No. 2 Krazan & Associates, Inc. Offices Serving The Western United States 230 feet at the crest of the steep slope. From the crest of the slope, the ground surface slopes downward at an initial gradient of about 50 percent, reduces to a gradient of approximately 30 percent over the central portion of Lot 3, and then continues downward at a gradient of about 50 percent over the lower western third of the lot to elevation 150 feet at the southwestern corner of the site. We understand ground cover west of the crest of the steep slope of Lot 3 consists of trees and brush, with low grass covering the remainder of the site. Ground cover of Lot 1 and 2 consists of several trees, low grass, and some bare areas. GEOLOGY The Washington Division of Geology and Earth Resources Geologic Map classifies the site as Vashon glacial till consisting of gravelly sands and silts. The USDA Natural Resources Conservation Services (NRCS) Soil Survey of King County has mapped the site soils as belonging to the Indianola and Alderwood series. The Indianola series, mapped in the northeastern corner of the site, are glacial outwash soils comprised of gravelly sandy loam on 5 to 15 percent slopes. These soils are in Hydrologic Soil Class A, and exhibit low run-off, high infiltration, and slight to moderate erosion hazard. The remainder of the site is mapped as Alderwood and Kitsap series (AkF), which are classified as glacial till soils found on steep slopes that exhibit high run-off, low permeability, and severe erosion hazard. The Alderwood soils are in Hydrologic Soil Class B. These soils often exhibit a short term perched water condition as the groundwater tends to flow laterally to seeps at the bottom of the steep slopes. EXISTING SUBSURFACE CONDITIONS BES conducted one soil test boring to a depth of 51.5 feet below the existing ground surface (bgs), as well as five auger borings to a depth of 4 to 5 feet bgs within Lot 3. No field explorations were conducted on Lot 1 or Lot 2. The test boring was conducted within the northeastern portion of Lot 3, while the auger borings were excavated primarily along the crest of the steep slope. According to BES’ test boring log, undocumented fill containing some debris and having relative densities ranging from very loose to medium dense was encountered to a depth of about 12 feet bgs. The fill was underlain by medium dense to very dense natural sands and very dense (“hard”) silt soils to the explored depth of the test boring. BES indicated groundwater was not observed in the boring after its completion, but was recorded at a depth of 19 feet bgs about a month later in a pvc observation well installed within the boring. CONCLUSIONS AND RECOMMENDATIONS General In our opinion, from a geotechnical engineering perspective, an onsite stormwater infiltration system is not feasible on this site due to the presence of existing fill, the anticipated low permeability of the natural soils, and the slope stability and erosion hazard of the existing steep slopes on Lot 3. Existing fill was encountered up to a depth of 12 feet in Boring 1 conducted within Lot 3 by Bergquist Engineering Services, as well as in the auger borings conducted along the crest of the steep slope. The fill material was classified as being in predominantly a very loose to loose relative density, and debris was observed within the fill layer. Onsite infiltration systems are designed based on infiltration rates for native soil conditions. The variable composition and relative density of the existing fill soils are not suitable for consideration of an onsite infiltration system. We do not know if the fill material is present on Lot 1 and Lot 2 since to our knowledge subsurface explorations were not conducted for these lots.

Offices Serving The Western United States Title 21A.06.415 of the King County Code defines Erosion Hazard Area as “an area underlain by soils that is subject to severe erosion when disturbed. These soils include, but are not limited to, those classified as having a severe to very severe erosion hazard according to the United States Department of Agriculture Soil Conservation Service, the 1990 Snoqualmie Pass Area Soil Survey, the 1973 King County Soils Survey or any subsequent revisions or addition by or to these sources such as any occurrence of River Wash (“Rh”) or Coastal Beaches (“Cb”) and any of the following when they occur on slopes inclined at fifteen percent or more:” A. The Alderwood gravelly sandy loam (“AgD”); B. The Alderwood and Kitsap soils (“AkF”); C. The Beausite gravelly sandy loam (“BeD” and “BeF”); D. The Kitsap silt loam (“KpD”); E. The oval gravelly loam (“OvD” and “OvF”; F. The Ragnar fine sandy loam (“RaD”); and G. The Ragnar-Indianola Association (“RdE”). Based on the USDA NRC’s classification of the portion of the site west of the steep slope crest as Alderwood and Kitsap series (AkF) with severe erosion potential and existing slopes greater than 15 percent, this portion of the site meets the criteria for an Erosion Hazard Area. Based on our review of the definition of Landslide Hazard Areas presented in Title 21A.06.680 of the King County Code, the site is considered a Landslide Hazard Area due to the existing slopes being greater than 15 percent and the presence of impermeable soils. The USDA NRC estimates the saturated permeability (Ksat) of the Alderwood and Kitsap series soils as ranging between 0.0 and 0.06 inches per hour. The glacial till below the densic stratum of the Alderwood series is generally considered weakly cemented and impermeable. Based on our review of the referenced report by BES, the plan drawing by Pittman, and the geologic information for the site, it is our opinion that the site is not feasibly for an onsite infiltration system. Project stormwater runoff will need to be directed to a controlled facility, such as the city stormwater system. Limitations This letter has been prepared for the exclusive use of Abbey Road Group Land Development Services Company, LLC and their design team, for the specific application to the subject site. Our conclusions are based on our review of the site and subsurface conditions as presented in the referenced report by Bergquist Engineering Services (BES) and the site plan drawing by Pittman Engineering, and on our interpretation of the current conditions only. If conditions are encountered that appear to be different than those described in the report by BES, we should be notified so that we may review and verify or modify our recommendations. This letter does not include any environmental site assessment for the presence or absence of hazardous and/or toxic materials in the soil, groundwater or atmosphere, or the presence of wetlands or other biological conditions. This letter also does not include any recommendations for design or construction of site improvements, including building foundations or pavement sections.
