The development will include the construction of four,two story, apartment buildings, a surface parking lot,pathways, landscaping, service utilities, and associated right-of-way improvements along the Project frontage. See Figure 2 (TIR Worksheet)for a summary of the Project. 1.2 Pre-developed Condition The Project site is bounded by the Glennwood Avenue right-of-way to the north, a multi-family residential complex to the south,the vacated Harrington Place NE right-of-way to the east, and Harrington Avenue NE to the west. The existing land cover onsite consist of a park play area and playfield and two single family homes with associated lawns and dirt driveways. The topography is relatively flat with a less than 2% average slope across the site. Based on a topographic survey provided by Benchmark Surveying LLC,there is no existing storm drainage infrastructure on-site. Based on survey contours,existing stormwater runoff sheet flows across the site, from the northeast to the southwest and is likely collected by existing bioretention swales along Harrington Avenue NE or by a downstream catch basin located within the right- of-way. Figure 3—Existing Conditions shows existing condition flow patterns. Table 1 -Pre- Developed and Developed Surface Coverage Areas includes a summary of the existing site coverage areas.

Other proposed site features include concrete patios and walkways,two refuse enclosures,bicycle storage facilities, ROW frontage improvements, and associated landscaping improvements and infrastructure. Table 1 Pre-Developed and Developed Surface Coverage Areas includes a summary of the proposed site coverage areas. 1.4 Proposed Storm Drainage Facilities In general, stormwater runoff will be directed to a new stormwater detention vault, located beneath the proposed parking lot, and then to the existing storm main line within the Harrington RHA Sunset Court Apartments,MIGISvR#15030 Section 1 Technical Information Report Page 4 January 13,2016 Avenue NE right-of-way. Building downspouts will be tightlined to the proposed detention vault and pollution generating runoff from the parking lot will be directed to bioretention planters for treatment prior to being routed to the detention vault and then to the public storm drainage system. Runoff from landscaped areas is expected to infiltrate. The site will be graded towards the on-site stormwater planters; in the event that runoff from landscape areas does not infiltrate it will be collected by the planters. Figure 4—Proposed Conditions shows developed condition flow patterns. 1.5 Soils Based on a geotechnical engineering study performed by Geotech Consultants, Inc. (see Geotechnical Report in Appendix A)the subsurface conditions of the site consist of approximately 1' of topsoil,underlain by 2'—6' feet of sand with gravel,underlain by glacial till. The City of Renton Amendments(City Amendments)to the King County Surface Water Design Manual (KCSWDM) identifies the site as being underlain by Arents,Alderwood material, 6 to 15 percent slope(AmC), see Figure 5-Soils Map. In accordance with the KCSWDM,the soils onsite were tested for infiltration rates, soil gradation, organic content, and cation exchange capacity. Infiltration test results provided 60 and 96 in/hr infiltration rates for the two locations tested; however,the relatively shallow glacial till layer makes infiltration unfeasible across most of the site. Soil gradation results are provided in the Geotechnical Report,Appendix A. The organic content was determined to be 0.5%, in test pit#2, at a depth of two feet. The cation exchange capacity at the same location was tested to be 3.81 meq/100g. See Appendix A for a copy of the Geotechnical Report and information regarding cation exchange capacity and organic content.

The flow chart in Figure 6—Flow Chart for Determining the Type of Drainage Review Required in conjunction with Table 6— Requirements Applied Under Each Drainage Review Type in the City Amendments,provides the framework to determine which Core Requirements apply to the Project. These figures are provided in the City Amendments as Figure 1.1.2.A and Table 1.1.2.A. The Project will add/replace more than 2,000 square feet of impervious surface;therefore,the Project must comply with Core Requirements#1-#8 and Special Requirements#1-#6. 2.1.1 Core Requirements Core Requirement#1:Discharge at Natural Location Preliminary stormwater plans have been prepared; a copy is included in Appendix B. Following on-site treatment and detention, stormwater runoff will be discharged at the natural discharge location",the City of Renton storm drainage system within Harrington Avenue NE. Core Requirement#2: Offsite Analysis All projects are required to perform an offsite analysis per Section 1.2.2.1 of the City Amendment. A Level 1 analysis has been performed and is presented in Section 3.0 of this report. Core Requirement#3:Flow Control The project is located in a peak rate flow control (existing conditions) standard area based on the City of Renton Flow Control Application Map, see Figure 7. Flow control will be provided by routing runoff to a detention vault located beneath the surface parking lot. See Appendix B for preliminary stormwater plans, including vault size and location. Core Requirement#4: Conveyance System Runoff from the Project site will be conveyed to the existing,piped, storm drainage system in the right-of-way via a piped, onsite storm drainage system. The stormwater conveyance system has been sized to convey flows from the 25-year storm event. See Appendix D for conveyance calculations. Core Requirement#5:Erosion and Sediment Control Erosion and Sediment Control(ESC)Plans have not been prepared for the Project at this time. ESC plans will be submitted,together with stormwater plans, as part of the building permit submittal. Additionally,the Contractor will be required to prepare a Stormwater Pollution Prevention and Spill(SWPPS)Plan to comply with Section RHA Sunset Court Apartments,MIGISvR#15030 Section 2 Technical Information Report Page 21 January 13,2016 2.3.1.1 of the City Amendment. Applicable Best Management Practices (BMPs)will be selected and maintained by the Project Owner to control pollution. Core Requirement #6:Maintenance and Operations A maintenance and operations manual has been prepared and is provided in Section 10.0 of this report. Core Requirement#7:Financial Guarantees and Liability All required bonds will be paid by the Owner prior to permit approval,per Section 1.2.7 of the City Amendments. A bond quantities worksheet will be prepared at a later date and included in the final TIR. Core Requirement#8: Water Quality Normally, as the Project is a multifamily residential project,it would be subject to the requirements of the Enhanced Basic Water Quality Menu per Section 1.2.8.1.A of the City Amendments; however, as the Project will drain entirely via a piped system to the major receiving water"Lake Washington, it is exempt from providing enhanced treatment and only subject to the requirements of basic treatment. Treatment of pollution generating impervious surfaces will be provided with bioretention planters. Treatment of pollution generating pervious surfaces will not be explicitly provided; a Landscape Management Plan that controls solids, pesticides, and fertilizers leaving the Site will be created for the Project. See section 1.2.8.1 of the City Amendment for additional information on Water Quality requirements and exceptions. 2.1.2 Special Requirements Special Requirement#1: Other Adopted Requirements No other area-specific requirements apply to this Project. Special Requirement#2:Flood Hazard Delineation Not applicable. The Project is not adjacent to a flood hazard area. Special Requirement#3:Flood Protection Facilities Not applicable. There are no flood protection facilities on or adjacent to the site. Special Requirement#4:Source Control Not applicable. The Project does not require a commercial building or commercial site development permit. Special Requirement#5: Oil Control Not applicable. This site is not classified as high-use. RHA Sunset Court Apartments,MIGISvR#15030 Section 2 Technical Information Report Page 22 January 13,2016 Special Requirement#6:Aquifer Protection Area The Project is located within the Aquifer Protection Area, Zone 2. The project is proposing a bioretention planter with underdrain for water quality treatment of the parking lot. As the measured infiltration rate of the on-site soils is greater than nine inches per hour, a facility liner will be required per Special Requirement#6 (Section 1.3.6 of the City Amendments). The bioretention soil within the planter will have sufficient organic content to meet the organic soil layer requirements for a treatment liner per 6.2.4.2 of the KCSWDM. See the Geotechnical Report in Appendix A, Section 1.3.6 of the City Amendment, and Section 6.2.4 of the KCSWDM). A map of the Aquifer Protection Area zones is provided in Figure 8.

City of Renton's Storm and Surface Water Utility Systems Map (COR GIS). 3.2.2 Field Inspections A field inspection has not yet been conducted and will be conducted at a later date. 3.2.3 Drainage System Description and Problem Descriptions Figure 9 shows a map of the downstream system reviewed. Figure 10 includes a description of each drainage system element.No downstream drainage issues were identified by the Level 1 downstream analysis. 3.2.4 Mitigation of Existing or Potential Problems As no downstream issues were identified,no mitigation measures are proposed. As the ProjectgppJ will be matching existing runoff rates from the site,no potential downstream drainage problems are anticipated as a result of the proposed improvements. The downstream system and need for mitigation will be re-evaluated following the forthcoming field inspection.

The Project site is bounded by the Glennwood Avenue right-of-way to the north, a multi-family residential complex to the south,Harrington Place NE to the east, and Harrington Avenue NE to the west. The existing land cover onsite consist of a park play area and playfield and two single family homes with associated lawns and dirt driveways. Based on a topographic survey provided by Benchmark Surveying LLC,there is no existing storm drainage infrastructure on- site. See Appendix B for a survey drawing of the existing site conditions. 4.2 Proposed Site Hydrology In general, stormwater runoff will be directed to a new stormwater detention vault located beneath the proposed parking lot, and then to the existing storm main line within the Harrington Avenue NE right-of-way. Building downspouts will be tightlined directly to the proposed detention vault and pollution generating runoff from the parking lot will be directed to bioretention planters for treatment prior to being routed to the detention vault and. Runoff from landscaped areas is expected to infiltrate. In the event that runoff from landscape areas does not infiltrate,the site will be graded to sheet flow runoff from landscaped areas to the on-site stormwater planters. See Appendix B for the proposed drainage plan. 4.3 Performance Standards The Project is located in a peak flow rate control standard area and in a basic water quality area for treating a multifamily site draining via a piped system to Lake Washington. Therefore,the Project must comply with the Peak Flow Control Standard and provide basic water quality facilities for pollution generating surfaces. A detention vault will be provided beneath the surface parking lot to provide flow control for the Project. A bioretention planter with 18"of bioretention soil and an underdrain will provide water quality treatment for the pollution generating parking lot. Runoff from the parking lot will sheet flow into the bioretention planter,be infiltrated through 18"of bioretention soil, and then be collected in the planter underdrain which will convey the treated water to the detention vault. Permeable pavements will be provided to meet the requirement for onsite flow control BMPs. Figure 11 was used to help determine the flow control BMP requirements; this figure is also available as Figure 5.2.1.A in the KCSWMM. Pervious concrete pavement will be designed and installed in accordance with Section C.2.6 of the KCSWMM. Runoff calculations showing that the developed site meets and exceeds the Peak Flow Control Standard are provided in Appendix C. Flow control credit for the permeable pavements is not currently being applied to the detention RHA Sunset Court Apartments,MIGISvR#15030 Section 4 Technical Information Report Page 38 January 13,2013 vault sizing calculation in order provide a conservative estimate of the required improvements. Flow control credit(per Section 1.2.3.2,Table 1.2.3.0 Flow Control BMP Facility Sizing Credits in the KCSWMM) for the permeable pavement will be applied at a future phase of the Project.

The detention vault has been sized to detain flows to the Peak Flow Control Standard(matching the existing runoff rates for the 2-, 10-, and 100-year, 24- hour storm peak flows). Table 5 provides the Project peak flows for the existing and developed conditions. Locations of pervious concrete pavements may be found in the plan set within Appendix B. See Section 10 of this report for facility maintenance requirements. 4.5 Water Quality Facilities Water quality treatment for the pollution generating parking lot will be provided by a bioretention planter. Runoff from the parking lot will sheet flow into the planter where it will infiltrate through 18" of bioretention soil. The bioretention planter has been size to filter 99.7% of the runoff from the pollution generating parking lot which exceeds the 91%minimum requirement for basic water quality treatment. See appendix C for water quality treatment sizing calculations.

See drainage plans in Appendix B. 5.2 Proposed Conveyance System Roof runoff from each of the four proposed buildings will be collected in downspout tightlines and directed to the on-site detention vault where the runoff will be detained,prior to being released into the public storm drainage system within Harrington Avenue NE. Runoff from the pollution generating parking lot will sheet flow into stormwater planters (with under drains)that will filter collected runoff through 18" of bioretention soil. The planter underdrains and overflows will be connected to the detention vault and routed to the public storm drainage system in Harrington Avenue NE following detention. In general,runoff from the non-building and non-parking areas will either infiltrate into the ground through the landscape area amended soils or will sheet flow into the stormwater planters. 1 Capacity for a 6"PVC pipe at 2.0%was calculated using FlowMaster®hydraulic modeling software. The full flow capacity(Appendix D)for a 6"PVC pipe at 2.0%is 1.11 cfs. The 25 year runoff rate from the developed site is 0.288 cfs, as determined using KCRTS modeling software(see Appendix C). No pipes less than 6"diameter or less than 2% slope are being proposed for the project; therefore,the proposed conveyance system will have sufficient capacity. II .

The scope of our services consisted of exploring site surface and subsurface conditions, and then developing this report to provide recommendations for general earthwork and design criteria for foundations, retaining walls, and stormwater infiltration. This work was authorized by your acceptance of our proposal dated August 11,2015. The attached report contains a discussion of the study and our recommendations. Please contact us if there are any questions regarding this report, or for further assistance during the design and construction phases of this project. Respectfully submitted, GEOTECH CONSULTANTS, INC. 54Zs..72 James H.Strange, P Associate TRC/JHS: at GEOTECH CONSULTANTS, INC. GEOTECHNICAL ENGINEERING STUDY Proposed Housing Development 1144—1158 Harrington Avenue Northeast Renton,Washington This report presents the findings and recommendations of our geotechnical engineering study for the site of the proposed housing development to be located in Renton. Development of the property is in the planning stage, and detailed plans were not made available to us. We understand that the development will consist of approximately 50 units. The lowest level of the structures will be close to the existing ground surface. Infiltration of stormwater has been proposed for the project. If the scope of the project changes from what we have described above, we should be provided with revised plans in order to determine if modifications to the recommendations and conclusions of this report are warranted. SITE CONDITIONS SURFACE The Vicinity Map, Plate 1, illustrates the general location of the irregularly-shaped site in Renton. The site is bordered to the west by Harrington Avenue Northeast, to the east by Harrington Place Northeast, to the south by a multi-story condominium building, and to the north by three multi-family buildings. The ground surface within the site slopes very slightly down toward the south. The western portion of the site is developed with two, one-story duplexes and a few detached sheds. The duplex yards are vegetated with grass lawns and a few landscaping bushes and trees. Most of the eastern side of the site is a public park, with a few children's play structures. The area around those structures is surrounded by shredded bark, and the remainder of the park is grass lawn. The northeast corner of the site is undeveloped, and vegetated with field grass and a few mature deciduous trees. A concrete retaining wall is located along the south edge of the site. This wall has a height of about 2 to 4 feet, and faces a cut for the adjacent southern parking area. SUBSURFACE The subsurface conditions were explored by excavating 10 test pits and three hand-augered test holes at the approximate locations shown on the Site Exploration Plan, Plate 2. Our exploration program was based on the proposed construction, anticipated subsurface conditions and those encountered during exploration, and the scope of work outlined in our proposal. The test pits were excavated on August 25, 2015 with a rubber-tired backhoe. A geotechnical engineer from our staff observed the excavation process, logged the test pits, and obtained representative samples of the soil encountered. "Grab" samples of selected subsurface soil were collected from the backhoe bucket. The Test Pit Logs are attached to this report as Plates 3 through 7. The test holes were excavated on September 14, 2015 using hand tools. A geotechnical engineer from our staff conducted and logged the test holes. The Test Hole Logs are attached to this report as Plates 8 and 9. ii GEOTECH CONSULTANTS, INC. Renton Housing Authority JN 15342 October 15,2015 Page 2 Soil Conditions The test pits and test holes generally encountered about one foot of topsoil at the ground surface. Test Pit 10, located near the southwest corner of the site, revealed 1.5 feet of fill overlying topsoil. Test Hole 3, close to the play strictures in the southeast corner of the site, encountered shredded bark, geotextile, and gravel that extended to a depth of about 1.3 feet; no topsoil was exposed by that exploration. Test Pit 6 was located between the park and Harrington Place Northeast, and revealed a few inches of gravel but no topsoil. Below the topsoil and the surface material described above, the explorations encountered sand with gravel that was loose to medium;dense. This sand extended to depths of 2 to 6 feet, and was medium-dense within about 3 feet of the ground surface. The sand with gravel extended to the greatest depths in the northeast third of the site. The sand with gravel was underlain by medium- dense to dense silty sand with gravel in the explorations, with the exception of those in which we completed infiltration testing, as described below. The silty sand with gravel has been glacially- overridden, has very low permeability, and is referred to as glacial till. Groundwater Conditions No groundwater seepage was observed in the test pits or test holes. It should be noted that groundwater levels vary seasonally with rainfall and other factors. We anticipate that perched groundwater could be found above the silty sands encountered in our explorations, especially during the normally wet winter and spring months. The stratification lines on the logs represent the approximate boundaries between soil types at the exploration locations. The actual transition between soil types may be gradual, and subsurface conditions can vary between exploration locations. The logs provide specific subsurface information only at.the locations tested. The relative densities and moisture descriptions indicated on the test pit logs are interpretive descriptions based on the conditions observed during excavation. The compaction of test pit backfill was not in the scope of our services. Loose soil will therefore be found in the area of the test pits. If this presents a problem, the backfill will need to be removed and replaced with structural fill during construction. INFILTRATION TESTING We conducted EPA falling head infiltration testing at Test Pit 5 at a depth of 2.5 feet and in Test Hole 1 at a depth of 3 feet. As required by the City of Renton,the infiltration testing was completed in general accordance with the procedure outlined in the 2009 Surface Water Design Manual. The final measured infiltration rate at Test Pit 5 was 96 inches per hour, and the measured rate at Test Hole 1 was 60 inches per hour. Impermeable silty sand/glacial till soil was encountered in our test holes at the following depths: Test Pit 1 . . . 2 3. 4 5*. 6 7 8 9 10 Depth ', : 2 3 5.5 6 2.5+ ' 6 5 3.5 3.5 4 Test Hole 1* 2 : 3 `, Depth • 3+ 3.8 2.5 Test Pit 5 and Test Hole 1 were infiltration holes and were not excavated to the glacial till. LABORATORY TESTING We obtained a sample from a depth of 2 feet in Test Pit 2 and provided that sample to an analytical laboratory. That facility determined that the Cation Exchange Capacity of the sample was 3.81 and the Total Organic Carbon was 0.528%. GEOTECH CONSULTANTS,INC. Renton Housing Authority JN 15342 October 15, 2015 Page 3 CONCLUSIONS AND RECOMMENDATIONS GENERAL THIS SECTION CONTAINS A SUMMARY OF OUR STUDY AND FINDINGS FOR THE PURPOSES OF A GENERAL OVERVIEW ONLY. MORE SPECIFIC RECOMMENDATIONS AND CONCLUSIONS ARE CONTAINED IN THE REMAINDER OF THIS REPORT. ANY PARTY RELYING ON THIS REPORT SHOULD READ THE ENTIRE DOCUMENT. The test pits conducted for this study encountered native, medium-dense soil within a few feet of the ground surface. Conventional footings bearing directly on that material will be appropriate for the structure foundations. The sand and gravel soils present below the surficial topsoil has high permeability, as our infiltration testing demonstrates, and stormwater infiltration in that material is feasible. However, the underlying dense glacial till soil has very low permeability and water will accumulate above it and develop a perched water condition. We expect that most surface water at the site in its current condition infiltrates through the topsoil and sandy soil, and is then essentially prevented from continuing to flow any deeper by glacial till. A proper, designed infiltration system will need to be extremely shallow to duplicate the current condition. As the 2009 Surface Water Design Manual requires, any infiltration system should introduce water at least 3 feet above the surface of the low-permeability silty sand/glacial till. Shallow permeable pavement could work in certain areas and depths at the site, but we recommend that any infiltration systems for concentrated flow (roof runoff) or excavated infiltration systems (drywells/trenches)be avoided as the clearance to the glacial till is not available in most areas of the site. Additionally, no infiltration system should be located within 75 feet of the retaining wall at the south edge of the property. In our opinion, a design infiltration rate of 2 inches per hour can be can be used for the permeable pavement infiltration. The erosion control measures needed during the site development will depend heavily on the weather conditions that are encountered. We anticipate that a silt fence will be needed around the downslope sides of any cleared areas. Existing pavements, ground cover, and landscaping should be left in place wherever possible to minimize the amount of exposed soil. Rocked staging areas and construction access roads should be provided to reduce the amount of soil or mud carried off the property by trucks and equipment. Wherever possible, the access roads should follow the alignment of planned pavements. Trucks should not be allowed to drive off of the rock-covered areas. Cut slopes and soil stockpiles should be covered with plastic during wet weather. Following clearing or rough grading, it may be necessary to mulch or hydroseed bare areas that will not be immediately covered with landscaping or an impervious surface. On most construction projects, it is necessary to periodically maintain or modify temporary erosion control measures to address specific site and weather conditions. The drainage and/or waterproofing recommendations presented in this report are intended only to prevent active seepage from flowing through concrete walls or slabs. Even in the absence of active seepage into and beneath structures, water vapor can migrate through walls, slabs, and floors from the surrounding soil, and can even be transmitted from slabs and foundation walls due to the concrete curing process. Water vapor also results from occupant uses, such as cooking and bathing. Excessive water vapor trapped within structures can result in a variety of undesirable conditions, including, but not limited to, moisture problems with flooring systems, excessively moist air within occupied areas, and the growth of molds, fungi, and other biological organisms that may be harmful to the health of the occupants. The designer or architect must consider the potential vapor sources and likely occupant uses, and provide sufficient ventilation, either passive or mechanical,to prevent a build up of excessive water vapor within the planned structure. Geotech Consultants, Inc. should be allowed to review the final development plans to verify that the recommendations presented in this report are adequately addressed in the design. Such a plan review would be additional work beyond the current scope of work for this study, and it may include revisions to our recommendations to accommodate site, development, and geotechnical constraints that become more evident during the review process. GEOTECH CONSULTANTS, INC. Renton Housing Authority JN 15342 October 15,2015 Page 4 We recommend including this report, in its entirety, in the project contract documents. This report should also be provided to any future property owners so they will be aware of our findings and recommendations. SEISMIC CONSIDERATIONS In accordance with the International Building Code (IBC), the site soil profile within 100 feet of the ground surface is best represented by Site Class Type D (Stiff Site Class). As noted in the USGS website, the mapped spectral acceleration value for a 0.2 second (Ss) and 1.0 second period (Si)equals 1.43g and 0.54g, respectively. The IBC states that a site-specific seismic study need not be performed provided that the peak ground acceleration be equal to Sos/2.5, where Sos is determined in ASCE 7. It is noted that SOS is equal to 2/3Sms. SMs equals Fa times Ss,where Fa is determined in Table 11.4-1. For our site, Fa = 1.0. The calculated peak ground acceleration that we utilized for the seismic-related parameters (earth pressures and seismic surcharges)of this report equals 0.38g. The site soils are not susceptible to seismic liquefaction because of their medium-dense to dense nature and the absence of near-surface groundwater. CONVENTIONAL FOUNDATIONS The proposed structure can be supported on conventional continuous and spread footings bearing on undisturbed, medium-dense, native soil. We recommend that continuous and individual spread footings have minimum widths of 12 and 16 inches,. respectively. Exterior footings should also be bottomed at least 18 inches below the lowest adjacent finish ground surface for protection against frost and erosion. The local building codes should be reviewed to determine if different footing widths or embedment depths are required. Footing subgrades must be cleaned of loose or disturbed soil prior to pouring concrete. Depending upon site and equipment constraints,this may require removing the disturbed soil by hand. An allowable bearing pressure of 2,500 pounds per square foot (psf) is appropriate for footings supported on competent native soil. A one-third increase in this design bearing pressure may be used when considering short-term wind or seismic loads. For the above design criteria, it is anticipated that the total post-construction settlement of footings founded on competent native soil will be about one-inch, with differential settlements on the order of one-half-inch in a distance of 30 feet along a continuous footing with a uniform load. Lateral loads due to wind or seismic forces may be resisted by friction between the foundation and the bearing soil, or by passive earth pressure acting on the vertical, embedded portions of the foundation. For the latter condition, the foundation must be either poured directly against relatively level, undisturbed soil or be surrounded by level, well-compacted fill. We recommend using the following ultimate values for the foundation's resistance to lateral loading: PARAMETERULTIMATE VALUE Coefficient of Friction 0.45 Passive Earth Pressure 350 pcf Where: pcf is Pounds per Cubic Foot, and Passive Earth Pressure is computed using the equivalent fluid density. If the ground in front of a foundation is loose or sloping, the passive earth pressure given above will not be appropriate. We recommend maintaining a safety factor of at least 1.5 for the foundation's resistance to lateral loading,when using the above ultimate values. GEOTECH CONSULTANTS,INC. Renton Housing Authority JN 15342 October 15, 2015 Page 5 FOUNDATION AND RETAINING WALLS Retaining walls backfilled on only one side should be designed to resist the lateral earth pressures imposed by the soil they retain. The following recommended parameters are for walls that restrain level backfill: PARAMETER VALUE Active Earth Pressure*35 pcf Passive Earth Pressure 350 pcf Coefficient of Friction 0.45 Soil Unit Weight 130 pcf Where: pcf is Pounds per Cubic Foot, and Active and Passive Earth Pressures are computed using the equivalent fluid pressures. For a restrained wall that cannot deflect at least 0.002 times its height,a uniform lateral pressure equal to 10 psf times the height of the wall should be added to the above active equivalent fluid pressure. The design values given above do not include the effects of any hydrostatic pressures behind the walls and assume that no surcharges, such as those caused by slopes,vehicles, or adjacent foundations will be exerted on the walls. If these conditions exist, those pressures should be added to the above lateral soil pressures. Where sloping backfill is desired behind the walls,we will need to be given the wall dimensions and the slope of the backfill in order to provide the appropriate design earth pressures. The surcharge due to traffic loads behind a wall can typically be accounted for by adding a uniform pressure equal to 2 feet multiplied by the above active fluid density. Heavy construction equipment should not be operated behind retaining and foundation walls within a distance equal to the height of a wall, unless the walls are designed for the additional lateral pressures resulting from the equipment. The values given above are to be used to design only permanent foundation and retaining walls that are to be backfilled, such as conventional walls constructed of reinforced concrete or masonry. It is not appropriate to use the above earth pressures and soil unit weight to back-calculate soil strength parameters for design of other types of retaining walls, such as soldier pile, reinforced earth, modular or soil nail walls. We can assist with design of these types of walls, if desired. The passive pressure given is appropriate only for a shear key poured directly against undisturbed native soil, or for the depth of level,well-compacted fill placed in front of a retaining or foundation wall. The values for friction and passive resistance are ultimate values and do not include a safety factor. Restrained wall soil parameters should be utilized for a distance of 1.5 times the wall height from corners or bends in the walls. This is intended to reduce the amount of cracking that can occur where a wall is restrained by a corner. Wall Pressures Due to Seismic Forces The surcharge wall loads that could be imposed by the design earthquake can be modeled by adding a uniform lateral pressure to the above-recommended active pressure. The recommended surcharge pressure is 8H pounds per square foot(psf), where H is the design retention height of the wall. Using this increased pressure, the safety factor against sliding and overturning can be reduced to 1.2 for the seismic analysis. Retaining Wall Backfill and Waterproofing Backfill placed behind retaining or foundation walls should be coarse, free-draining structural fill containing no organics. This backfill should contain no more than 5 percent silt or clay particles and GEOTECH CONSULTANTS, INC. Renton Housing Authority JN 15342 October 15,2015 Page 6 have no gravel greater than 4 inches in diameter. The percentage of particles passing the No.4 sieve should be between 25 and 70 percent. If the native sand or silty sand is used as backfill, a drainage composite similar to Miradrain 6000 should be placed against the backfilled retaining walls. The drainage composites should be hydraulically connected to the foundation drain system. Free-draining backfill or gravel should be used for the entire width of the backfill where seepage is encountered.)) For increased protection, drainage.composites should be placed along cut slope faces, and the walls should be backfilled entirely with free-draining soil. The later section entitled Drainage Considerations should also be reviewed for recommendations related to subsurface drainage behind foundation and retaining walls. The purpose of these backfill requirements is to ensure that the design criteria for a retaining wall are not exceeded because of a build-up of hydrostatic pressure behind the wall. Also, subsurface drainage systems are not intended to handle large volumes of water from surface runoff. The top 12 to 18 inches of the backfill should consist of a compacted, relatively impermeable soil or topsoil, or the surface should be paved. The ground surface must also slope away from backfilled walls to reduce the potential for surface water to percolate into the backfill. Water percolating through pervious surfaces (pavers, gravel, permeable pavement, etc.) must also be prevented from flowing toward walls or into the backfill zone. The compacted subgrade below pervious surfaces and any associated drainage layer should therefore be sloped away. Alternatively, a membrane and subsurface collection system could be provided below a pervious surface. It is critical that the wall backfill be placed in lifts and be properly compacted, in order for the above- recommended design earth pressures to be appropriate. The wall design criteria assume that the backfill will be well-compacted in lifts no thicker than 12 inches. The compaction of backfill near the walls should be accomplished with hand-operated equipment to prevent the walls from being overloaded by the higher soil forces that occur during compaction. The section entitled General Earthwork and Structural Fill contains additional recommendations regarding the placement and compaction of structural fill behind retaining and foundation walls. The above recommendations are not intended to waterproof below-grade walls, or to prevent the formation of mold, mildew or fungi in interior spaces. Over time, the performance of subsurface drainage systems can degrade, subsurface groundwater flow patterns can change, and utilities can break or develop leaks. Therefore, waterproofing should be provided where future seepage through the walls is not acceptable. This typically includes limiting cold-joints and wall penetrations, and using bentonite panels or membranes on the outside of the walls. There are a variety of different waterproofing materials and systems, which should be installed by an experienced contractor familiar with the anticipated construction and subsurface conditions. Applying a thin coat of asphalt emulsion to the outside face of a wall is not considered waterproofing, and will only help to reduce moisture generated from water vapor or capillary action from seeping through the concrete. As with any project, adequate ventilation of basement and crawl space areas is important to prevent a build up of water vapor that is commonly transmitted through concrete walls from the surrounding soil, even when seepage is not present. This is appropriate even when waterproofing is applied to the outside of foundation and retaining walls. We recommend that you contact an experienced envelope consultant if detailed recommendations or specifications related to waterproofing design, or minimizing the potential for infestations of mold and mildew are desired. The General, Slabs-On-Grade, and Drainage Considerations sections should be reviewed for additional recommendations related to the control of groundwater and excess water vapor for the anticipated construction. SLABS-ON-GRADE The building floors can be constructed as slabs-on-grade atop competent native soil, or on structural fill. The subgrade soil must be in a firm, non-yielding condition at the time of slab construction or underslab fill placement. Any soft areas encountered should be excavated and replaced with select, imported structural fill. GEOTECH CONSULTANTS, INC. Renton Housing Authority JN 15342 October 15, 2015 Page 7 Even where the exposed soils appear dry,water vapor will tend to naturally migrate upward through the soil to the new constructed space above it. This can affect moisture-sensitive flooring, cause imperfections or damage to the slab, or simply allow excessive water vapor into the space above the slab. All interior slabs-on- grade should be underlain by a capillary break drainage layer consisting of a minimum 4-inch thickness of clean gravel or crushed rock that has a fines content (percent passing the No. 200 sieve) of less than 3 percent and a sand content (percent passing the No. 4 sieve) of no more than 10 percent. Pea gravel or crushed'.rock are typically used for this layer. As noted by the American Concrete Institute (ACI) in the Guides for Concrete Floor and Slab Structures, proper moisture protection is desirable immediately below any on-grade slab that will be covered by tile,wood, carpet, impermeable floor coverings, or any moisture-sensitive equipment or products. ACI also notes that vapor retarders such as 6-mil plastic sheeting have been used in the past, but are now recommending a minimum 10-mil thickness for better durability and long term performance. A vapor retarder is defined as a material with a permeance of less than 0.3 perms, as determined by ASTM E 96. It is possible that concrete admixtures may meet this specification, although the manufacturers of the admixtures should be consulted. Where vapor retarders are used under slabs, their edges should overlap by at least 6 inches and be sealed with adhesive tape. The sheeting should extend to the foundation walls for maximum vapor protection. If no potential for vapor passage through the slab is desired, a vapor barrier should be used. A vapor barrier, as defined by ACI, is a product with a water transmission rate of 0.01 perms when tested in accordance with ASTM E 96. Reinforced membranes having sealed overlaps can meet this requirement. The General, Permanent Foundation and Retaining Walls, and Drainage Considerations sections should be reviewed for additional recommendations related to the control of groundwater and excess water vapor for the anticipated construction. EXCAVATIONS AND SLOPES Excavation slopes should not exceed the limits specified in local, state, and national government safety regulations. Temporary cuts to a depth of about 4 feet may be attempted vertically in unsaturated soil, if there are no indications of slope instability. However, vertical cuts should not be made near property boundaries, or existing utilities and structures. Based upon Washington Administrative Code (WAC) 296, Part N, the soil at the subject site would generally be classified as Type B. Therefore, temporary cut slopes greater than 4 feet in height should not be excavated at an inclination steeper than 1:1 (Horizontal:Vertical), extending continuously between the top and the bottom of a cut. The above-recommended temporary slope inclination is based on the conditions exposed in our explorations, and on what has been successful at other sites with similar soil conditions. It is possible that variations in soil and groundwater conditions will require modifications to the inclination at which temporary slopes can stand. Temporary cuts are those that will remain unsupported for a relatively short duration to allow for the construction of foundations, retaining walls, or utilities. Temporary cut slopes should be protected with plastic sheeting during wet weather. It is also important that surface runoff be directed away from the top of temporary slope cuts. Cut slopes should also be backfilled or retained as soon as possible to reduce the potential for instability. Please note that sand or loose soil can cave suddenly and without warning. Excavation, foundation, and utility contractors should be made especially aware of this potential danger. These recommendations may need to be modified if the area near the potential cuts has been disturbed in the past by utility installation,or if settlement-sensitive utilities are located nearby. All permanent cuts into native soil should be inclined no steeper than 2:1 (H:V). Water should not be allowed to flow uncontrolled over the top of any temporary or permanent slope. All permanently exposed slopes should be seeded with an appropriate species of vegetation to reduce erosion and improve the stability of the surficial layer of soil. GEOTECH CONSULTANTS, INC. Renton Housing Authority JN 15342 October 15,2015 Page 8 DRAINAGE CONSIDERATIONS Footing drains should be used where: (1) crawl spaces or basements will be below a structure; (2) a slab is below the outside grade; or, (3) the outside grade does not slope downward from a building. Drains should also be placed at the base of all earth-retaining walls. These drains should be surrounded by at least 6 inches of 1-inch-minus, washed rock that is encircled with non-woven, geotextile filter fabric (Mirafi 140N, Supac 4NP, or similar material). At its highest point, a perforated pipe invert should be at least.6 inches below the bottom of a slab floor or the level of a crawl space. The discharge pipe for subsurface drains should be sloped for flow to the outlet point. Roof and surface water drains must not discharge into the foundation drain system. A typical drain detail is attached to this report as Plate 10. For the best long-term performance, perforated PVC pipe is recommended for all subsurface drains. As a minimum, a vapor retarder, as defined in the Slabs-On-Grade section, should be provided in any crawl space area to limit the transmission of water vapor from the underlying soils. Crawl space grades are sometimes left near the elevation of the bottom of the footings. As a result, an outlet drain is recommended for all crawl spaces to prevent an accumulation of any water that may bypass the footing drains. Providing even a few inches of free draining gravel underneath the vapor retarder limits the potential for seepage to build up on top of the vapor retarder. No groundwater was observed during our field work. If seepage is encountered in an excavation, it should be drained from the site by directing it through drainage ditches, perforated pipe, or French drains,or by pumping it from sumps interconnected by shallow connector trenches at the bottom of the excavation. The excavation and site should be graded so that surface water is directed off the site and away from the tops of slopes. Water should not be allowed to stand in any area where foundations,slabs, or pavements are to be constructed. Final site grading in areas adjacent to buildings should slope away at least 2 percent, except where the area is paved. Surface drains should be provided where necessary to prevent ponding of water behind foundation or retaining walls. A discussion of grading and drainage related to pervious surfaces near walls and structures is contained in the Foundation and Retaining Walls section PAVEMENT AREAS The pavement section may be supported on competent, native soil or on structural fill compacted to a 95 percent density. The pavement subgrade must be in a stable, non-yielding condition at the time of paving. Granular structural fill or geotextile fabric may be needed to stabilize soft,wet, or unstable areas. To evaluate pavement subgrade strength, we recommend that a proof roll be completed with a loaded dump truck immediately before paving. In most instances where unstable subgrade conditions are encountered, an additional 12 inches of granular structural fill will stabilize the subgrade, except for very soft areas where additional fill could be required. The subgrade should be evaluated by Geotech Consultants, Inc.,after the site is stripped and cut to grade. Recommendations for the compaction of structural fill beneath pavements are given in the section entitled General Earthwork and Structural Fill. The performance of site pavements is directly related to the strength and stability of the underlying subgrade. The pavement for lightly loaded traffic and parking areas should consist of 2 inches of asphalt concrete (AC) over 4 inches of crushed rock base (CRB) or 3 inches of asphalt-treated base (ATB). We recommend providing heavily loaded areas with 3 inches of AC over 6 inches of CRB or 4 inches of ATB. Heavily loaded areas are typically main driveways, dumpster sites, or areas with truck traffic. Increased maintenance and more frequent repairs should be expected if thinner pavement sections are used. Water from planter areas and other sources should not be allowed to infiltrate into the pavement subgrade. The pavement section recommendations and guidelines presented in this report are based on our experience in the area and on what has been successful in similar situations. ((We can provide recommendations based on expected traffic loads and California Bearing Ratio (CBR) tests, if requested.)) As with any pavements, some maintenance and repair of limited areas can be expected as the pavement ages. Cracks in the pavement should be sealed as soon as possible after they become evident, in order to reduce the potential for GEOTECH CONSULTANTS,INC. Renton Housing Authority JN 15342 October 15, 2015 Page 9 degradation of the subgrade from infiltration of surface water. For the same reason, it is also prudent to seal the surface of the pavement after it has been in use for several years. To provide for a design without the need for any maintenance or repair would be uneconomical. GENERAL EARTHWORK AND STRUCTURAL FILL All building and pavement areas should be stripped of surface vegetation, topsoil, organic soil, and other deleterious material. It is important that existing foundations be removed before site development. The stripped or removed materials should not be mixed with any materials to be used as structural fill, but they could be used in non-structural areas, such as landscape beds. Structural fill is defined as any fill, including utility backfill, placed under, or close to, a building, behind permanent retaining or foundation walls, or in other areas where the underlying soil needs to support loads. All structural fill should be placed in horizontal lifts with a moisture content at, or near, the optimum moisture content. The optimum moisture content is that moisture content that results in the greatest compacted dry density. The moisture content of fill is very important and must be closely controlled during the filling and compaction process. The allowable thickness of the fill lift will depend on the material type selected, the compaction equipment used, and the number of passes made to compact the lift. The loose lift thickness should not exceed 12 inches. We recommend testing the fill as it is placed. If the fill is not sufficiently compacted, it can be recompacted before another lift is placed. This eliminates the need to remove the fill to achieve the required compaction. The following table presents recommended relative compactions for structural fill: LOCATION OF FILL MINIMUM RELATIVE PLACEMENT COMPACTION Beneath slabs or 95% walkwa s Filled slopes and behind 90% retainin• walls 95%for upper 12 inches of Beneath pavements subgrade; 90% below that level Where:Minimum Relative Compaction is the ratio,expressed in percentages, of the compacted dry density to the maximum dry density, as determined in accordance with ASTM Test Designation D 1557-91(Modified Proctor). Structural fill that will be placed in wet weather should consist of a coarse, granular soil with a silt or clay content of no more than 5 percent. The percentage of particles passing the No. 200 sieve should be measured from that portion of soil passing the three-quarter-inch sieve. LIMITATIONS The conclusions and recommendations contained in this report are based on site conditions as they existed at the time of our exploration and assume that the soil and groundwater conditions encountered in the test pits are representative of subsurface conditions on the site. If the subsurface conditions encountered during construction are significantly different from those observed in our explorations, we should be advised at once so that we can review these conditions and reconsider our recommendations where necessary. Unanticipated conditions are commonly encountered on construction sites and cannot be fully anticipated by merely taking samples in test GEOTECH CONSULTANTS,INC. Renton Housing Authority JN 15342 October 15,2015 Page 10 pits. Subsurface conditions can also vary between exploration locations. Such unexpected conditions frequently require making additional expenditures to attain a properly constructed project. It is recommended that the owner consider providing a contingency fund to accommodate such potential extra costs and risks. This is a standard recommendation for all projects. This report has been prepared for the exclusive use of Renton Housing Authority and its representatives for specific application to this project and site. Our conclusions and recommendations are professional opinions derived in accordance with our understanding, of current local standards of practice, and within the scope of our services. No warranty is expressed or implied. The scope of our services does not include services related to construction safety precautions, and our recommendations are not intended to direct the contractor's methods, techniques, sequences, or procedures, except as specifically described in our report for consideration in design. Our services also do not include assessing or minimizing the potential for biological hazards, such as mold, bacteria, mildew and fungi in either the existing or proposed site development. ADDITIONAL SERVICES Geotech Consultants, Inc. should be retained to provide geotechnical consultation, testing, and observation services during construction. This is to confirm that subsurface conditions are consistent with those indicated by our exploration, to evaluate whether earthwork and foundation construction activities comply with the general intent of the recommendations presented in this report, and to provide suggestions for design changes in the event subsurface conditions differ from those anticipated prior to the start of construction. However, our work would not include the supervision or direction of the actual work of the contractor and its employees or agents. Also, job and site safety, and dimensional measurements, will be the responsibility of the contractor. During the construction phase, we will provide geotechnical observation and testing services when requested by you or your representatives. Please be aware that we can only document site work we actually observe. It is still the responsibility of your contractor or on-site construction team to verify that our recommendations are being followed, whether we are present at the site or not. The scope of our work did not include an environmental assessment, but we can provide this service, if requested.

This site was previously approved for a 10 unit townhome but the development has been revised to increase to 50 units. The site is located just north of the Sunset Terrace neighborhood. The site is shown in Figure 1. Note that Sunset Lane is currently being redesigned. The revised alignment will create a loop road and remove Harrington Avenue N between the Sunset Lane loop. Refer to Figure 1. 2.0 Trip Generation Site generated traffic volumes were calculated using data from the Institute of Transportation Engineers(ITE) Trip Generation Manual,8th Edition, (2008). Trip generation rates were selected using the ITE Land Use Code 230,Residential Condominium/Townhouse. The results of this analysis are shown in Table 1.

This is an increase of 232 vehicles per day over the previously planned 10-unit townhouse development. j 3.0 Trip Distribution The townhouses will have a parking lot with two access points. One will be located off of Harrington Avenue 1 NE and the other access point will roughly align with Harrington Place NE. It is anticipated that 30%of the site generated traffic will travel to the north with 70% traveling to the south through the reconstructed Sunset Lane. Further breakdown of the traffic assumes that 45%will continue to access Sunset Boulevard via NE 10th Street with the remaining 25% utilizing Harrington Avenue NE These percentages for traffic distribution were developed based on existing traffic volumes and peak hour counts of the surrounding street network. The trip distribution results are shown in Figure 1. The trip assignment was calculated using existing traffic counts, by using the PM Peak Hour— ADT ratio to convert peak hour counts into ADT units. This relationship was then applied to the site generated trips to determine the PM Peak Hour values for each street and which route they were more likely to take. These Sunset Court Page 1 Traffic Impact Analysis Ally Community Development,LLC September 10,2015 1 File location:\\evt-files\clients\Ally Community Development,LLC\Promo Efforts120150193-Sunset Court TIA\TIA 5tuff\TIA sunset court-Draft.docx l results are shown in Figure 2 which reveals the anticipated increase in each turning movement due only to the new Sunset Court townhome development. 4.0 Intersection Level of Service Analysis PM peak hour traffic counts were obtained for three intersections along NE 12th Street(at Edmonds Avenue NE,at Harrington Avenue NE,and at Kirkland Avenue NE) by National Data and Surveying Services in August 2015. The remaining five intersections had turning movement counts obtained from the Sunset Boulevard project traffic report conducted by Perteet. These eight intersections are shown in Figures 2-5. The existing turning movements are shown in Figure 3. The future analysis was performed for the development's anticipated year of opening, 2017. The baseline turning movement counts were developed using a 1% annually compounding growth rate. The baseline turning movements are shown in Figure 4. Following the development of the baseline turning movements, the trips generated from the proposed development were added to the 2017 baseline condition to reach the future conditions after development and are shown in Figure 5. The existing, baseline, and future scenarios were analyzed to determine the level of service(LOS)at each intersection within the study area. The results of this analysis are shown in Table 2.

This minor change in delay will not result in a change of LOS at any of the studied intersections. 5.0 Transportation Impact Fees The intersection level of service analyses indicate that none of the studied intersections will operate at a deficient level of service. Due to this,no offsite improvements are required due to this development. The City of Renton does not specify the transportation impact fee for townhouse developments. The closest equivalent fee would be the"Condominium" land use which requires a transportation impact fee of$1,180.84 per dwelling unit. For this 50-unit development,the total transportation impact fee required is$59,042.00. 6.0 Conclusions The Sunset Court Townhome development is proposed to have 50 units ranging from one to three bedrooms. This development is expected to generate 291 additional trips per day to the existing street network, with 26 of those occurring at the PM peak hour. This development is not expected to lower the level of service at any of the surrounding intersections included within the study area; therefore, the Renton Housing Authority will not be conditioned to provide any off-site improvements.

The privacy of individuals in residential uses shall be provided for. Guidelines-Primary entries shall face the street,serve as a focal point,and allow space for social interaction.All entries shall include features that make them easily identifiable while reflecting the architectural character of the building. The primary entry shall be the most visually prominent entry.Pedestrian access to the building from the sidewalk,parking lots,and/or other areas shall be provided and shall enhance the overall quality of the pedestrian experience on the site. Buildings 1,2 and 4 are oriented towards Harrington Avenue NE or vacated Glennwood Avenue NE with pedestrian entries to the buildings all directly accessed off of entry walks that pass through front yards and directly connect to sidewalks along the ROW. Entries are easily identifiable by being recessed and provided with weather-protection overhangs.Building 3 is oriented to a landscaped pedestrian only central courtyard Transition to surrounding development Guidelines:Careful siting and design treatment shall be used to achieve a compatible transition where new buildings differ from surrounding development in terms of building height,bulk and scale. Buildings are articulated to divide larger architectural elements into smaller increments and roof lines are designed to reduce apparent bulk.Building's 1 and 2,which front Harrington Avenue NE are lower in order to transition to smaller scale residential buildings to the west and north. Location and design of parking Guidelines-Surface pa)king shall be located and designed so as to reduce the visual impact of the parking area and associated vehicles.Large areas of surface parking shall also be designed to accommodate future infill development. schemata workshop inc 1172012th avenue,seattle wa 98122 www.schemataworkshop.com v 206.285.1589 f 206.285.2701 schemata workshop Surface parking is located at the south edge of the property across from the neighboring site's carport,and at the east side of the property,across from the back side of a large retail building.Both parking areas are.screened by 10-foot bioretention landscaping areas at the property line Vehicular access Guidelines:Vehicular access to parking garages and parking lots shall not impede or interrupt pedestrian mobility. The impacts of curb cuts to pedestrian access on sidewalks shall be minimized. Resident and visitor access to parking.is at the SW corner off of Harrington Avenue NE.Alleys are not available.The number of curb cuts along Harrington Avenue NE.is reduced from three to one. Emergency vehicle access to the site is at the SW corner off of Harrington Avenue NE as well as the NE corner off of 11th Avenue N.The drive'aisle at the NE corner off of 11th Avenue N is restricted with an automated gate for use only by emergency vehicles.The surface of the restricted;portion of the drive is grass crete,for a more pedestrian friendly experience where it meets the sidewalk. Pedestrian circulation Guidelines:The pedestrian environment shall be given priority and importance in the design ofprojects. Sidewalks and/or pathways shall be provided and shall provide safe access to buildings from parking areas.Providing pedestrian connections to abutting properties is an important aspect of connectivity and encourages pedestrian activity and shall be considered.Pathways shall be easily identifiable to pedestrians and drivers Numerous pedestrian pathways are provided within the site,linking all buildings,parking areas,amenity spaces,and service areas.Interior site pathways have clear sight lines and also link buildings to existing sidewalks in the ROW. Actual pathways within the parking areas are differentiated visually and materially.A mid-block pathway is provided from the sidewalk along Harrington Avenue NE to the central courtyard. Elevated exterior pedestrian walkways at buildings 3 and 4 are oriented towards the central courtyard with the intent of encouraging community and increasing safety.Nooks on the exterior walkways are intended to encourage informal gathering. Common space Guidelines Developments located at street intersections should provide pedestrian-oriented space at the street corner to emphasize pedestrian activity.Recreation and common open space areas are integral aspects of quality development that encourage pedestrians and users. These areas shall be provided in an amount that is adequate to be functional and usable;they shall also be landscaped and located so that they are appealing to users and pedestrians. Within the central courtyard,recreation space is set aside for children.Rather than use off-the-shelf play structures,the client has requested the reuse of boulders and logs to serve as natural play structures. Bike parking and a barbecue area are also proposed. Building character and massing,rooflines,and materials Guidelines:Building facades shall be modulated and/or articulated to reduce the apparent size of buildings,break up long blank walls,add visual interest and enhance the character of the neighborhood.Articulation,modulation,and their intervals should create a sense of scale important to residential buildings On buildings 1 and 2,modulation occurs at entries and typically at walls between units,resulting in facades that modulate every ten feet.On buildings 3 and 4,which do not face a public ROW,modulation is typically at 13 or 26 foot modules.Since building 4 is longer than 160'in length,it is also modulated vertically at the ends of the building to help reduce the overall bulk of the structure. Numerous discussions between the city and design team occurred during the fall of 2015 addressing concerns that the design of the buildings were too stark for Renton.The design team also met with community members on November 12,2015 to engage current RHA residents and elicit their feedback. schemata workshop January 19,2016,revised September;27,2016 project narrative to Matthew Herrera City of Renton Community&Economic Development Planning Division 1055 South Grady Way Renton,WA 98057 rT- \/ D from Grace Kim OCT U Schemata Workshop,Inc. 1720 12th Avenue 17.VF Seattle,WA 98122 PLANK. . 206.285.1589 I subject Site Plan Review Project Narrative project name RHA Sunset Court Apartments I project size Lot size=83,657 SF minus 1,901 SF ROW dedication=81,756 SF(1.88 acres).

A hammerhead turn-around has been paired-with an automated gate to Renton Fire Department standards. The emergency vehicle driveway is set 5 feet away from the adjacent property and is high strength grasscrete to reduce visual competition with the existing sidewalk along Harrington PI NE. Select panels of the existing sidewalk are sloped to meet the grade of the grasscrete driveway. Once complete,the driveway and automated gate will be clearly marked to prevent confusion and unsafe use of the vacated right of way on the neighboring parcel. In response to a concern brought up via email(attached),the water main has been relocated at the north side of the property to avoid other utilities and existing trees designated to be preserved. Additionally,exterior elevations for Building 3&4 have been developed further to fit the larger massing. Specifically,the siding type has been changed in various locations from fiber cement shingles to fiber cement board and batten.The rhythm of fenestration has also been revised.

Review comments may also need to be reviseld based on site planning and other design changes required by. City staff or made by the applicant. I have completed a preliminary review for the above-referenced proposal. The following comments are based on the pre-application submittal made to the City of Renton by the applicant. Water 1. The proposed development is within the City of Renton 565-pressure zone water service area. There is an existing 12-inch water main located in Harrington Ave NE (refer to City project plan no. W-3635) which can deliver a maximum flow,capacity of 2,350 gallons per minute (gpm). The static water pressure is about 93 psi at ground elevation of 350 feet. There is an existing 1-inch domestic water meter serving the existing house on the subject property(utility billing account reference no. 140092). 2. Based on the information submitted by the applicant, the City's Fire Prevention Department has determined the preliminary fire flow demand for the development is 2,750 gpm including the use of an automatic fire sprinkler system. 3. On-site and off-site water mains improvements are required to provide water service for fire protection and for domestic uses per City Code and development standards(RMC 4-6-010B) 4. In order to provide the required fire flow demand of 2,750 gpm, additional off-site water main extension of about 330 feet of 12-inch water main will be required along NE 10th Street from the existing 12-inch main in Harrington Ave NE to an existing 12-inch main (see plan no. W-3752)that ends at the intersection of NE 10th St and Sunset Lane NE. 5.

At"this time, the schedule for the construction of the improvements is not known. 6. Since the fire flow demand of the development exceeds 2,500 gpm, an on-site and looped 12-inch water main around the buildings is also required. A 15-foot wide utility easement is required for the on- site water main. No buildings, structures or vaults shall be placed within the easement area and within 10 feet of the water main. 7. Installation of fire hydrant(s) as required by Renton Fire Prevention. The number and location of the hydrants shall be determined based on the City's review of the final building plans and site plan. 8. Installation of a separate fire sprinkler stub to each building with a detector double check valve assembly (DDCVA) for backflow prevention. The DDCVA shall,be installed in an outside underground vault or in the building sprinkler rooms if it meets.the conditions as shown on City's standard plan for the interior installation of a DDCVA. 9. Installation of a separate domestic water meter for each building with a double check valve assembly DCVA) behind each meter. The sizing of the domestic water meters shall be done in accordance with Chapter 6 of Uniform Plumbing Code.

Entries are easily identifiable by being recessed and provided with weather-protection overhangs.Building 3 is oriented to a landscaped pedestrian only central courtyard Transition to surrounding development Guidelines:Careful siting and design treatment shall be used to achieve a compatible transition where new buildings differ from surrounding development in terms of building height,bulk and scale. Buildings are articulated to divide larger architectural elements into smaller increments and roof lines are designed to reduce apparent bulk.Buildings 1 and 2,which front Harrington Avenue NE are lower in order to transition to smaller scale residential buildings to the west and north. Location and design of parking Guidelines:Surface parking shall be located and designed so as to reduce the visual impact of the parking area and associated vehicles.Large areas of surface parking shall also be designed to accommodate future infill developmet. `y jDkuF'G FEB 01 2016 e . 172012thiavenue#3,_seaittle•wa 98122 i anal)iN www.schemataworkshop.com v 206.285.1589 f 206.285.2701 schemata workshop Surface parking is located at the south edge of the property across from the neighboring site's carport,and at the east side of the property,across from the back side of a large retail building.Both parking areas are screened by 10-foot bioretention landscaping areas at the property line Vehicular access Guidelines:Vehicular access to parking garages and parking lots shall not impede or interrupt pedestrian mobility. The impacts of curb cuts to pedestrian access on sidewalks shall be minimized. Access to parking is at the SW corner off of Harrington Avenue NE and the NE corner off of 11`h Avenue N.Alleys are not available.The number of curb cuts along Harrington Avenue NE is reduced from three to one.Sidewalks are not currently located at the NE corner of the property where the driveway is proposed. Pedestrian circulation Guidelines:The pedestrian environment shall be given priority and importance in the design ofprojects. Sidewalks and/or pathways shall be provided and shall provide safe access to buildings from parking areas.Providing pedestrian connections to abutting properties is an important aspect of connectivity and encourages pedestrian activity and shall be considered.Pathways shall be easily identifiable to pedestrians and drivers Numerous pedestrian pathways are provided within the site,linking all buildings,parking areas,amenity spaces,and service areas.Interior site pathways have clear sight lines and also link buildings to existing sidewalks in the ROW. Numerous traffic calming speed bumps in the parking drive aisle are intended to make surface parking more pedestrian friendly. Actual pathways within the parking areas are differentiated visually and materially.A mid-block pathway is provided from the sidewalk along Harrington Avenue NE to the central courtyard. Elevated exterior pedestrian walkways at buildings 3 and 4 are oriented towards the central courtyard with the intent of encouraging community and increasing safety.Nooks on the exterior walkways are intended to encourage informal gathering. Common space Guidelines:Developments located at street intersections should provide pedestrian-oriented space at the street corner to emphasize pedestrian activity.Recreation and common open space areas are integral aspects ofquality development that encourage pedestrians and users. These areas shall be provided in an amount that is adequate to be functional and usable;they shall also be landscaped and located so that they are appealing to users and pedestrians. Within the central courtyard,recreation space is set aside for children.Rather than use off-the-shelf play structures,the client has requested the reuse of boulders and logs to serve as natural play structures.Bike parking and a barbecue area are also proposed. Building character and massing,rooflines,and materials Guidelines:Building facades shall be modulated and/or articulated to reduce the apparent size of buildings,breakup long blank walls,add visual interest,and enhance the character of the neighborhood.Articulation,modulation,and their intervals should create a sense of scale important to residential buildings On buildings 1 and 2,modulation occurs at entries and typically at walls between units,resulting in facades that modulate every ten feet.On buildings 3 and 4,which do not face a public ROW,modulation is typically at 13 or 26 foot modules.Since building 4 is longer than 160'in length,it is also modulated vertically at the ends of the building to help reduce the overall bulk of the structure. Numerous discussions between the city and design team occurred during the fall of 2015 addressing concerns that the design of the buildings were too stark for Renton.The design team also met with community members on November 12,2015 to engage current RHA residents and elicit their feedback. A •T 4 f/ schemata workshop September 19,2015 I J R II 49'4 variance justification FEB ® ZGCifY subject Site Plan Review Application—Variance Justification PLANNING DIVISION project title Sunset Court Apartments Sunset Court Apartments is a proposed low-rise development,with a mix of one-,two-,and three-bedroom units located in four-buildings which encircle a central landscaped commons.The existing site is flat and measures 81,756 SF(1.88 acres).All existing structures will be demolished and 47,589 SF of new housing is proposed;which ' will accommodate 50 apartment units.The zoning designation for this site is Center Village which requires structured parking per Renton Municipal Code 4-2-120A.The project owner,Renton Housing Authority(RHA), requests a variance to provide 50 at-grade surface parking stalls in lieu of providing the code required structured parking.As an affordable housing development intended to provide housing for individuals and families earning below 60%of area median income,surface parking is a cost-effective approach to meeting the parking demands of the RHA's tenant base and construction financing limits while also maintaining some of the park character for which the project is named. RHA has learned through ownership of public housing for more than 50 years that when possible,families are better accommodated in townhouse style units with private ground-related entries and on-site open space for children-a feature residents have enjoyed at the Sunset Terrace public housing project forthe past seven decades. For that reason;the Sunset Court Apartments project includes a mix of townhome units along with stacked flats served by surface parking lots.The design currently includes protection of several large,mature trees.The courtyard will feature a landscaped play area for children.The low-rise buildings proposed for the site will set a higher standard for density in this neighborhood where duplexes predominate,but will still maintain a character and scale suitable for families. The project will have three accessible units;(1)1-bedroom,(1)2-bedroom and(1)3-bedroom.The accessible units are proposed to be closest to the accessible parking spaces.Two units will be set aside for large families. Construction is currently planned to be conventional wood frame structures with 2 on-site trash enclosures and a common laundry room. The proposed concept will create a village-like community,with ready access to open space for families who will live at Sunset Court,and will provide an open,welcoming street presence along Harrington Ave NE.Vehicle access via driveways will be provided at the SW and NE corners of the site.The at-grade parking is proposed to be located on the southeast side of the property,and will be screened from existing and proposed right-of-ways surrounding the project by buildings and landscaping;consistent with the Urban Design Guidelines for District D per the Renton Municipal Code.Two-story townhome units,with ground related entries,will be the visible,street- facing presence of this project along Harrington Ave NE and three-story apartment buildings will line the north property line,which may in the future become a continuation of Glennwood Ave NE.While parking will not be visible from the street,the entrances to the parking area will be visible but will look like residential driveways. In addition to more rental units,the remaining project will feature large landscaped areas-including some existing trees that will be preserved and protected.The surface parking lots will be designed with traffic control bumps and coordinated landscaped islands to provide a slow lane of traffic through the parking area and variation in the shape schemata workshop inc 11720 12th avenue,seattle wa 98122 www.schemataworkshop.com v 206.285.1589 f 206.285.2701 schemata workshop and contour of the vehicular route.These features will allow the parking area to double as hardscape for children to ride bikes, play ball,and other engage in other play activities. The Renton Housing Authority wishes to maintain a park-like setting for Sunset Court Apartments,because this is consistent with the Renton Municipal Code Urban Design Guidelines and because RHA knows that large families are most successful in units with direct access to outdoors. Surface grade parking willenable the project to meet the following Renton Municipal Code 4-3-100 Urban Design Regulations: E.SITE DESIGN AND BUILDING LOCATION intent is to o "ensure that buildings are located in relation to streets and other buildings so that the Vision of the City of Renton can be realized for high-density urban environment,.so that businesses enjoy visibility from public rights-of-way,and to encourage pedestrian activity throughout the district" o "make building entrances convenient to locate and easy to access,and ensure that building entries further the pedestrian nature of the fronting sidewalk and the urban character of the district" o "shape redevelopment projects so that the character and value ofRenton's'long-established neighborhoods are preserved. This will be a transitional project to help bridge the existing neighborhood to the potential higher density build out allowed on the adjacent properties.This project will establish a benchmark for development that preserves the character of the neighborhood while dramatically increasing density.The proposed project has been designed to have a significant number of street facing residential units-21 of the 50 units will have residential entrances along Harrington Ave NE and Glenwood Ave NE.The remaining units have exterior doors opening onto the common open space—whether at grade or accessed from exterior walkways and stairs.The site and buildings have been designed to provide for very visible pedestrian activity within and around the site.There is also pedestrian access at the NE corner of the site that will provide a convenient path to the nearby commercial district. If the project were required to have structured parking,it is likely that there would be fewer at grade residential entries and a much reduced pedestrian environment.A larger apartment building with structured parking would have more interior circulation,very different from the proposed exterior circulation of this project.The proposed village like concept of the design is in keeping with the character of the existing neighborhood that is primarily comprised of duplexes with street related entrances. F. PARKING AND VEHICULAR ACCESS intent is to 'maintain active pedestrian environments along streets by placing parking lots in back of buildings". The project is consistent with both of the Surface Parking requirements: 1. Parking shall be located so that no surface parking is located between: a.A building and the front property line;and/or b.A building and the side property line(when on a corner lot,). 2. Parking shall be located so that it is screened from surrounding streets by buildings,landscaping, and/or gateway features as dictated by location." The proposed parking lot area will be obscured by landscaping and buildings,and will not be located along nor is the primary visual feature of either Harrington Ave NE or Glennwood Ave NE.There is a proposed ten foot landscape buffer between the parking and south property line. G. PEDESTRIAN ENVIRONMENT intent is to "provide safe and attractive pedestrian connections to buildings,parking garages,and parking lots" The village concept of Sunset Court Apartments includes a network of clear pedestrian pathways connecting each of the five buildings to the outdoor common space in the center of the site,the parking lot,as well as to Harrington Ave NE and Glennwood Ave NE. If the project were required to provide enclosed,structured parking,the layout of the site would be required to change and an interior common open space would no longer be possible.The pedestrian circulation on site would not allow for the same level of clear,open views from one side of the site to the other but would be obstructed with interior schemata workshop buildings to accommodate the increase in dimension of unit,or to accommodate an additional parking structure. H. LANDSCAPING/RECREATION AREAS/COMMON OPEN SPACE intent is to provide visual relief in areas of expansive paving or structures;define logical areas ofpedestrian and vehicular circulation;and add to the aesthetic enjoyment of the area by the community. To have areas suitable for both passive and active recreation by residents, workers,and visitors;provide these areas in sufficient amounts and in safe and convenient locations;and provide the opportunity for community gathering in p/aces centrally located and designed to encourage such activity" The proposed site design with surface parking allows for a large central common open space surrounded by the proposed buildings.The'open space is intended to be the focus of the site,while the proposed parking area is obscured from view from the open space by the residential buildings.The open space will be designed to allow for recreation areas for both children and adults.All 50 proposed residential units have entrances facing the common open space. Programmatically,the interior of all the units have the kitchens facing the common open space.These planning strategies allow for the most eyes on the public open space for safety. I. BUILDING ARCHITECTURAL DESIGN intent is to "encourage building design that is unique and urban in character, comfortable on a human scale,and uses appropriate building materials that are suitable for the Pacific Northwest climate" The proposed site design with surface.parking allows for five smaller human scaled buildings that are more in keeping with the surrounding existing context of the neighborhood.The buildings maintain a strong frontage on the primary streets surrounding the site and are consistent with creating a more urban character to the neighborhood.The materials will be of a residential project scale including lap and panel siding. The zoning code requirement for residential uses in the Center Village zone per RMC 4-2-120A is: Required parking shall be located underground or under building(on the first floor of the structure),or in an attached or detached structure.Any additional parking may not be located between the building and public street unless located within a structured parking garage." The City of Renton may issue a variance to allow for surface parking at this site without negative impact to neighboring uses.The existing four parcels that make up the proposed project site are currently a city park,an empty parcel and two parcels each with a duplex apartment building. Maintaining the park-like environment at this site is a more aesthetically pleasing and programmatically beneficial alternative to a large 50-unit single apartment building with interior parking and fewer pedestrian entrances.The design of the five-building low-rise village community is not overwhelming to the surrounding neighborhood and will provide for greater sightlines to and through the property from the adjacent rights of way.As illustrated in the bulleted arguments above,the proposed design meets the intent of the Renton Design Regulations and the Renton Municipal Code without structured parking.

The Sunset Area Community Neighborhood is shown in Exhibit 1.Sunset Terrace is the central approximately 7-acre property in the Potential Sunset Terrace Redevelopment subarea of the Sunset Area Community Neighborhood in Exhibit 1.The Potential Sunset Terrace Redevelopment subarea includes Sunset Terrace plus some peripheral sites that have been master planned for redevelopment along with Sunset Terrace for a total of about 12.4 acres. Redevelopment of this area envisions Sunset Terrace as a mixed-use, mixed-income community anchored by a new public library and a new park. Mixed-use sites will have both market rate and affordable rental housing in multi-story, multi-family townhomes and apartments,along with commercial and retail space. In order to meet,National Environmental Policy Act (NEPA) and State Environmental Policy Act (SEPA) requirements,the City of Renton issued the Draft Environmental Impact Statement(DEIS)for the City of Renton Sunset Area Community Planned Action on December 17,2010 and the Final Environmental Impact Statement(FEIS)for the City of Renton Sunset Area Community Planned Action on April 1,2011.1 The City served as the Responsible Entity(RE)for NEPA compliance,and the lead agency for SEPA compliance. In May 2011,the City of Renton completed a Record of Decision (ROD) in accordance with NEPA; and in June 2011 adopted a Planned Action Ordinance in accordance with SEPA for redevelopment of the Sunset Terrace area. Under SEPA, adevelopment application for a site-specific Planned Action project located within the Sunset Area will be designated a Planned Action if it meets the criteria in the adopted Planned Action Ordinance,as well as laws,codes, development regulations and standards of the City of Renton. The ROD and Planned Action established a range of growth and associated facility and infrastructure investments(e.g.,park,library,"green streets,"etc.)for the Sunset Area Community Planned Action Study Area,for the neighborhood as a whole and for the Sunset Terrace Redevelopment,a site then fully owned by the Renton Housing Authority (RHA). Redevelopment efforts have continued since 2011, including " issuance of a Demolition and Disposition permit for a Mixed Use Library redevelopment on a portion of the property and a purchase and sale agreement with a private developer. This was followed by a Demolition and Disposition permit for the balance of the Sunset Terrace property, which includes both market rate and affordable dwellings.There would be no net loss of affordable units; RHA has developed plans or has constructed units in the Sunset Area that could serve as replacement units for Sunset Terrace when redeveloped. J In 2014,the City, RHA and Colpitts proposed a revised Master Plan based on the selected alternatives of the ROD to promote coordinated development among the property owners.See Exhibit 2.The City studied changes to total dwellings,setbacks,and building heights,and also reclassified some local streets serving the Sunset Area to allow a more efficient roadway cross-section while still facilitating circulation. The changes to the development proposal to add more units and height,and to address street standards,was evaluated in a NEPA Reevaluation, pursuant to Section 58.47 of US Department of Housing and Urban Development's (HUD's). NEPA regulations, and a SEPA addendum (WAC 197-11-706). The combined Reevaluation and Addendum demonstrated that the Master Plan did not alter the original conclusions of 1 CH2MHill and ICF International.2011.Sunset Area Community Planned Action NEPA/SEPA Environmental Impact Statement. Final.April. (ICF 00593.10.) Bellevue and Seattle,WA. Prepared for City of Renton and the Renton Housing Authority, Renton, WA. December 2015 2 RENTON SUNSET COMMUNITY AREA REEVALUATION AND ADDENDUM the SEPA/NEPA FEIS; no new or different impacts would occur as a result of the modified plan. The Reevaluation and notice of Revised ROD were issued on December 8,2014. Following the December 2014 NEPA reevaluation, the City approved a Master Plan including a new Conceptual Plan for Sunset Terrace pursuant to Renton Municipal Code(RMC)Title IV.The revised Master Plan included additional dwellings,alternative building locations,height,and street reclassifications in the Sunset Terrace area.This Master Plan will facilitate the preparation of detailed Site Plans in phases over time; provides a point of consistency with applicable regulations;and provides more certainty regarding future development for members of the public and private developers. An amended Planned Action Ordinance-was adopted on December 8,2014. At this time,the City and RHA are considering amended plans that would develop replacement housing for the Sunset Terrace redevelopment on five parcels located outside but abutting the 2014 Master Plan area—three parcels would be added to the Sunset Court Park site and developed with 50 apartments and townhomes, and two parcels would be added to properties north of the "loop road" in the Harrington Park development providing 19 townhomes.See Exhibit 3.

However, consistent with the flexibility allowed by the adopted Master Plan, some units would be redistributed.The proposed developments would meet City standards for density, height, setbacks, transportation levels of service, connection to utilities, and would be subject to City parking codes, including procedures for modifying applicable standards. The new developments would be incorporated into an amended Master Plan pursuant to RMC Title IV. Also, the SEPA Planned Action Ordinance could be amended to include the revised Master Plan concept. As with the changes previously evaluated in 2014,the revisions proposed to the Master Plan at this time require a NEPA Reevaluation and SEPA Addendum to provide additional information about the proposal, to determine whether the proposed changes would result in any new or substantially different environmental impacts, and to assess whether the conclusions of the original EIS are still valid. This analysis would also provide the basis for amendments to the ROD and/or Planned Action Ordinance, if any.This Reevaluation and Addendum document is structured as follows: 1. Introduction 2. Sunset Area Alternatives 3. Environmental Analysis 4. Conclusions 2.0 SUNSET AREA ALTERNATIVES 2.1 Study Area The primary redevelopment area is the Sunset Terrace site illustrated on Exhibit 4. The Sunset Terrace primary redevelopment area includes sites H through O. Replacement housing sites include A through G,where units that meet the affordability and size requirements to house former Sunset Terrace residents or new residents are located. Site D was part of the original Sunset Terrace public housing site.Site D will provide replacement housing for existing dwellings on Sites H through O. It should be noted that Sites A and B have already developed and thus are not included in the Master Plan. The Master Plan completed in 2014 provides a coordinated plan of development for both the Sunset Terrace and Replacement sites C through 0. The proposed 2015 Master Plan amendment would add properties to sites E and F into the Master Plan,and redistribute some dwelling units, but would develop the same overall number of units as approved by the 2014 Master Plan.See Exhibit 5. All sites on Exhibit 5 were evaluated in the 2011 EIS for the Sunset Area Community Planned Action Area shown in Exhibit 1 and Exhibit 6. Most of the Master Plan Sites being reviewed in this document were previously considered in the Potential Sunset Redevelopment'Study Area (shaded in purple on Exhibit 1) or were considered"swap sites" (where housing replacement could occur) as shown in Exhibit 6. Three additional parcels abutting Sunset Court Park(site"F",a 2011"swap site")are-added to the Master Plan, and two additional parcels are added to the Redevelopment area (site "E"). See Exhibit 5 and Exhibit 7. The 2014 Master Plan area totaled about 12.4 acres. Sites E and F are extended in the amended 2015 Master Plan.See Exhibit 5.The updated 2015 Master Plan area would then equal about 14 acres: December 2015 6 1 RENTON SUNSET COMMUNITY AREA REEVALUATION AND ADDENDUM Exhibit 4.

Sites B,F,and X considered swap sites and included within neighborhood dwelling units. c Does not include swap sites B,F and X. Source:FEIS 2011,BERK 2014 The purpose of identifying two "Selected Sunset Area Alternatives" in the FEIS was to define a range of acceptable growth and designs considering the conceptual nature of the Sunset Terrace redevelopment plans in 2011,as well as the 20-year horizon of the broader neighborhood planned action. The Preferred Alternative was similar to Alternative 3 with slightly lower growth and a reconfiguration of park space and road network. The two alternatives were similar in terms of potential beneficial and adverse impacts and required mitigation measures. Since the original FEIS analysis, additional site planning for Sunset Terrace and other properties has occurred and some changes in the number or location of units have been considered. In 2014, 90 units were added to in the Sunset Terrace Master Plan area (sites C-O), compared to Alternative 3 in the FEIS, but the total number of units in the overall Sunset Area neighborhood remained the same._As well,other site planning considerations were addressed regarding building height, etc. as described above. The NEPA/SEPA Reevaluation conducted in 2014 showed-no substantive changes in impacts or required mitigation were needed as a result of the revised alternative, which is termed the "Reevaluation Alternative." Per the approved 2014 Master Plan, dwelling units may be redistributed among sites provided the Reevaluation conclusions are maintained. While the net units in Sunset Terrace are lower in 2015 than in 2014 per Exhibit 9,this is a reflection of the boundaries of the 2011 Potential Sunset Terrace Redevelopment Area (sites shaded purple in Exhibit 1 and Exhibit 6)that included sites A, C through,E,and G to 0 but did not include site F.Site F is included _ in the neighborhood units. Some potential dwelling units are proposed to be transferred among three individual Master Plan sites; these are identified with the "box" on Exhibit 10. However, the total number of units that could be developed in the Master Plan area would remain the same.

Site C would be reduced from 112 units to 68 units(a reduction of 44 units)and the units redistributed by 35 to Site F(an increase of 15 to 50)and by 9 to Site E(an increase of 10 to 19 units). In 2011, the Sunset Court Apartment concept (Site F) was considered as a "swap site" within the-larger project,whereby an existing park and parcels would be consolidated for a larger park. On Site F,the "swap site" is designed with the proposed Sunset Court Apartments.This will be a 50-unit multi-family housing project situated on four tax parcels.Tax parcel numbers(and addresses)are:722780- 1660(1144 Harrington Avenue NE);722780-1665 (1156 Glenwood Avenue NE); 722780-1780(vacant lot on Harrington Place NE); and,722780-1781(City park on Harrington.Place NE).The three additional lots are now included to make the design more conducive to the overall revitalization plan. On Site E, part of the Sunset Area Redevelopment in 2011, two parcels are added: 722780-1315 (1062 Glenwood Avenue NE) and 722780-1290 (1081 Harrington Avenue NE). The two parcels abut two other previously studied parcels in the Sunset Area Redevelopment. Collectively these are called Harrington Park. Approximately 19 townhomes and flats would be constructed on the sites. Six of the parcels (two lots that are part of the Sunset Court Apartment project and all four lots that are part of the Harrington Park project)contain one-story duplex residences that would be demolished. The Master Plan concept approved in 2014 would be revised per the 2015 Reevaluation Alternative shown in Exhibit 11 below.

No changes to the sites considered in the 2014 Reevaluation, and approved in the currently adopted Master Plan are anticipated. All environmental impacts were addressed in the 2014 NEPA/SEPA Reevaluation. Building Height All three sites, C, E, and F for the Edmonds Apartments, Harrington Park Apartments, and Sunset Court Apartments would be designed to meet allowable heights of their respective zones. Sites C and F are zoned Center Village with a maximum height of 50 feet (60 feet is allowed if there is ground floor commercial).Site C has been conceptually included in the Master Plan with no change to the maximum height; detailed site plans have not been prepared for the property at the time of this writing. Preliminary site plans prepared by RHA for Site F propose up to 40 feet in height under the maximum heights of the zone. Site E is zoned R-14 with a maximum height of 30 feet with proposed heights in preliminary site plans prepared by RHA proposed below that maximum. Density Sites C, E and F are consistent with the density requirements of the zones. See Exhibit 12. Density Standards and Results. Exhibit 12.

CV Zone:Assisted living bonus:1.5 times the maximum density may be allowed subject to conditions of RMC 4-9-065. Source:City of Renton Municipal Code;BERK Consulting 2015 Parking Subject sites will be required to meet City parking standards.The standard for parking is as follows: Attached dwellings in RM-U, RM-T, RM-F, R-14 and R-10 Zones:A minimum and maximum of 1.6 per 3 bedroom or large dwelling unit;1.4 per 2 bedroom dwelling unit;1.0 per 1 bedroom or studio dwelling unit. Attached dwellings within all other zones:1 per dwelling unit is required.A maximum of 1.75 per dwelling unit is allowed. Attached dwelling for low income:A minimum of 1 for each 4 dwelling units is required[0.25J.A maximum of 1.75 per dwelling unit is allowed. The sites propose parking consistent with the standards for low-income attached dwellings which may range from 0.25 to 1.75 per dwelling unit: December 2015 16 RENTON SUNSET COMMUNITY AREA REEVALUATION AND ADDENDUM Harington Park: 19 units,3 bedrooms, 25 stalls: Rate of 1.3 stalls per dwelling Sunset Court Apartments:50 units (1 bedroom (12);2 bedroom (20);3 bedroom (18): Rate of 0.98 Site C has not yet been the subject of a preliminary site plan, butrwill follow City codes as appropriate at the time such plans are submitted. Onsite Open Space In the CV zone,common open space is required to be provided at a rate offifty(50)square feet per unit. The City may allow substitutions in light of the public park provided adjacent to the properties. See RMC 4-1-240 for Common'Open Space Substitutions. This would likely require payment of a Fee in Lieu of Common Open Space.This would be addressed in future Site Plan Review applications. The Sunset Court Apartments have a central common space of over 7,750 square feet, larger than the minimum 2,500 square feet required (west of Buildings 3 and 4). The Harrington Park development has a common space of about 4,000 square feet(a larger common area between buildings 1 and 2 and a smaller common area between buildings 3 and 4), more than the minimum 950 square feet required. Private open space is required to be provided for each dwelling unit. Site plans show ground floor units with patio space and upper floors with balconies. At the time of Site Plan Review, the Director may approve modifications such as a percentage of units that may have alternative private open space standards if meeting the overall intent of design standards and other criteria at 4-3-100(F)and RMC 4-9- 250(D). I Setbacks Based on the Renton Municipal Code (RMC)zoning standards, 15 foot setbacks are needed from streets in the R-14 zones and 4-foot setbacks are required for unattached side yards. A maximum 15 foot street setback is required unless parking is accessed from an alley in which case the setback can be 10 feet. Further the parking would need to be located 20 feet from the street. The CV zone setback requires a minimum 10 foot setback which may be reduced to 0 feet as part of the site plan development review process, provided blank walls are not located within the reduced setback. The proposed Harrington Park street setbacks are 10 feet from NE 10th Street,and otherwise 15 feet from other streets.This is based on the parking being located behind the townhomes and accessed at least 20 feet away from the street. ' The Sunset Court Apartments site plans show units meet the required setbacks of 10 feet from streets. 2.4 Facility and Infrastructure Proposals Detailed infrastructure plans have not yet been submitted for the proposals. However,the Sunset Court Apartments and Harrington Park Apartments will be required to meet City standards for utility hookups, fire flow pressure,and stormwater standards. 2.5 Updated Land Cover/ Impervious Analysis The FEIS included an analysis of changes in impervious surfaces. Additionally, consistent with the requirements of Section 7 of the Endangered Species Act(ESA),the original 2011 proposal was evaluated with respect to potential effects ,on species listed or proposed for listing under the ESA.A biological assessment was prepared and submitted to the National Marine Fisheries Service (NMFS) in December 2010 for its concurrence with a finding that the proposal may affect, but is not likely to adversely affect, December 2015 17 RENTON S. ,iT COMMUNITY AREA REEVALw i iON AND ADDENDUM anadromous fish protected under the ESA,and would have no effect on any ESA-protected species under U.S. Fish and Wildlife Service jurisdiction. The City and NMFS corresponded in January, February, and April 2011 on.NMFS questions. The City received a letter of concurrence in May 2011.

Assumes that 35%of the 3.2 acre park site would be impervious. In comparison to Alternative 3,the preliminary analysis indicates•that total acres within the study area as a whole is higher due to the added properties for replacement housing, but total impervious area is lower December 2015 18 RENTON SUNSET COMMUNITY AREA REEVALUATION AND ADDENDUM due to the proposed designs of the sites, lesser Sunset Terrace Right-of-Way and the larger park.There are also less pollutant generating impervious surfaces (PGIS) as there is less surface parking in the preliminary site plans for the 2015 Reevaluation proposal than in Alternative 3; RNA has also indicated use of pervious parking and sidewalks for its developments similar to designs accomplished in the already constructed Kirkland Townhomes. Effective impervious area is also a little lower overall than Alternative 3.Therefore the 2015 Reevaluation Alternative is in the range of the prior analysis and no further analysis or conditions are needed in association with the proposal. The City communicated with NOAA and received confirmation that no new formal consultation is needed with regard to the ESA as the results are within the range previously received in the 2011 letter of concurrence. (pers corn,Janet Curran, NOAA to Rocale Timmons, City of Renton,October 30,2015) 2.6 Master Plan and Other Discretionary Applications The City intends to amend the Master Plan per RMC 4-9-200 to add in the five new parcels (three surrounding Sunset Court Park and' two added north of the loop road with the Harrington Park development). For each Master Plan site, a number of current and future permits are also anticipated. See Exhibit 17.This Reevaluation and Addendum for the revised proposal will also result in minor revisions of the ROD and Planned Action Ordinance to reflect the revised Master Plan. Other development permits and,approvals would also follow, such as lot line adjustments/subdivisions, right-of-way dedications and easements, phased/detailed site plans and associated design modifications where appropriate. Lastly, building and construction permits would be sought. 2.7 Phasing The redevelopment of the study area and broader neighborhood was anticipated to occur over a number of years.The Master(Plan sites will generally be phasedLover a 10 year period in approximately 5 phases.

It concludes that the revised Master Plan would not change impacts significantly from those identified in the FEIS. 3.1 Land Use The Land Use analysis in the FEIS concluded that the Sunset Area subarea would advance the purposes of the Comprehensive Plan and Center Village (CV) zoning district. It would serve as an incentive for other redevelopment opportunities near the study area. Anticipated growth would also help the City meet its 2031 housing and employment targets. These conclusions are still valid for the 2015 Reevaluation Alternative which proposes housing uses consistent with zoning and developed in coordination with the Master Plan. 3.2 Aesthetics As described in Sections 2.2 and 2.3, the Reevaluation Alternative will reallocate dwelling units among sites, but all sites will meet zoning densities, building heights and setbacks, open space, and landscaping. Design standards will apply. 3.3 Cultural Resources Three parcels were previously studied for potential cultural resources (Sunset Court Park and two Harrington Park lots on the south of the property) and a determination of "no effect" upon,historic properties was issued by the Washington State Department of Archaeology and Historic Preservation. For this 2015 Reevaluation,the added lots with duplexes were studied for potential historic resources and, the park studied again for potential archaeological resources.The report prepared by CRC(Attachment A) shows a new determination of"no effect"as of September 22, 2015. 3.4 Transportation Based on the results of the 2014 Reevaluation traffic analysis, overall transportation conditions are expected to operate similarly to the FEIS Preferred Alternative and Alternative 3.The intersection LOS at each study location is expected to be the same for all of the alternatives, in both 2015 and 2030. The difference in average vehicle delay at intersections studied in the 2014 Reevaluation Alternative is expected to be negligible compared to the delay with Alternative 3 or the Preferred Alternative. Similar mitigation measures as identified in the FEIS would still be required. The 2015 Reevaluation proposal retains the same level of neighborhood growth per the 2011 range of alternatives and the total number of housing units would remain the same neighborhood wide.A traffic impact analysis was prepared for the Sunset Court Apartments to confirm the relocation of units to the site (from 15 to 50 units) would not result in traffic impacts. No significant impacts were identified and the City's level of service standards would be met.,See Appendix B. 3.5 .Parks and Recreation The Sunset Court Park(Site F) is being relocated to a central larger park with the Sunset Terrace property redevelopment consistent with the adopted master plan. There is no change to the 2014 Reevaluation and FEIS results. December 2015 22 RENTON SUNSET COMMUNITY AREA REEVALUATION AND ADDENDUM 3.6 Public Services The overall conclusions of the FEIS for Selected Alternatives is expected to be similar for the Reevaluation Alternative since growth is the same as projected for the overall neighborhood and is similar to the 2014 Reevaluation proposal. 3.7 Utilities Water In the 2014 Reevaluation,a conceptual water main improvements layout for the proposed developments identified in the conceptual master plan was presented in Exhibit 1820 and remains valid for the 2015 Reevaluation. The City will require 12-inch water mains in all new public streets(Harrington Avenue NE,Sunset Lane NE, NE 10th Street, Glennwood Avenue NiE) to provide the estimated fire flow demand ranging from 3,000 gallons per minute (gpm) to 4,000 gpm based on the City Fire Prevention's review of various pre- application submittals. Portions of the water mains in SR 900'were installed by prior projects in the area. The section of the 12-inch main in Harrington Ave between Glennwood Avenue NE and NE 10th street was scheduled for implementation by the City in 2015 as part of the Harrington Ave Green Connection stormwater and water improvements project.Another section will be installed by the KCLS library project in NE 10th Street and in Sunset Lane NE up to the west property line of the KCLS project. A developer's extension of the section of 12-inch water main in SR 900 will be required to be a looped water system. The location of the new water main in SR 900 west of Harrington,whether it will be installed in the existing roadway pavement or in the future unimproved right-of-way must be carefully evaluated as part of the pre-design/design of the roadway improvements projects, and consider the need to accommodate existing and future public and private utilities, rockery/retaining walls,street trees, etc. Adequate horizontal separation (5-ft minimum and up to 10-feet) must be provided between the new water main and other utilities,structures,or trees.

Conditions, mitigation measures, andl conclusions regarding Environmental Health and Historic/Cultural Features are likewise unchanged. No environmental health conditions or cultural resources features are known in the Potential Sunset Terrace Redevelopment Subarea, but in case such features are uncovered. mitigation measures would apply. Built environment topics that are more suited to analysis under cumulative growth conditions include air quality and energy. The level of potential greenhouse gas emissions and energy use may be slightly higher in the Potential Sunset Terrace Redevelopment Subarea, but not in the neighborhood as a whole, and overall FEIS conclusions and mitigation measures are still applicable. Lastly, regarding socio-economics, housing, and environmental justice, it is anticipated that the overall conditions and impacts.regarding the potential for change in the neighborhood, need for relocation assistance, etc. identified in the FEIS are still valid, as the study area would still redevelop from present conditions to a mixed use,amenity-rich environment. 3.9 Monitoring and Review The Planned Action Ordinance includes monitoring and review measures to be considered within five years of the ordinance adoption;some measures are t-o be considered at the time of a NEPA Reevaluation compliance with neighborhood goals and Leadership in Environmental and Energy Design rating system for Neighborhood Development [LEED-ND] criteria or equivalent), though monitoring and review are directed to the Planned Action area as a whole. The City conducted a review in the 2014 Reevaluation. The next 5-year milestone, based on the effective date of the amended ordinance in 2014, would occur in 2019.At that point more development in the area would have occurred and there would be results to monitor. Nevertheless,this Reevaluation provides a review of the Planned Action Study Area Goals and Objectives and to the LEED-ND criteria in relation to the Reevaluation Alternative to contribute to the City's future 5-year review effort.See Exhibit 20 and Exhibit 20.In general,the 2015 Reevaluation Alternative continues to promote a public and private effort to create a mixed use, mixed income neighborhood supported by park, library, road,and stormwater improvements that increase quality of life.

In accordance with specific statutory authority and the U.S. Department of Housing and Urban Development's (HUD's) regulations at 24 Code of Federal Regulations(CFR)part 58,the City is authorized to assume responsibility for environmental review, decision-making, and action that would otherwise apply to HUD under NEPA. Additionally,the City is the lead agency and proponent of the broader Planned Action for the Sunset area which has had environmental'review:under Washington State Environmental Policy Act (SEPA) Revised Code of Washington [RCW]43.21(C). The City has performed joint NEPA/SEPA environmental review in cooperation with the Recipient, the Renton Housing Authority(RHA). Accordingly,the City prepared a Draft and Final EIS to analyze potential impacts of redevelopment of the Sunset Terrace public housing community. The Final Environmental Impact Statement(FEIS)supporting both milestones was issued April 1, 2011. The City initiated consultation with agencies and tribes regarding permit requirements and to identify any areas of concerns regarding the Sunset Terrace public housing redevelopment as'well as the overall Planned Action. Federal and state agencies were notified of comment opportunities through the scoping process, and were offered comment; opportunity on the Draft EIS. Two agencies were particularly consulted consistent with NEPA,the National Historic Preservation Act(Section 106),and the Endangered Species Act(Section 7). As.documented in the ROD and Environmental Review Record,the City received a letter of concurrence from NMFS in May 2011. The Biological Assessment and NMFS memoranda are included in the Environmental Review Record.The City also completed Section 106 consultation for Sunset Terrace redevelopment and all properties fronting NE Sunset Boulevard as documented in the ROD and Environmental Review Record. In addition,consistent with the federal Coastal Zone Management Act,the City received a letter of consistency from the State of Washington Department of Ecology(16 U.S.C. 1451- 1464). In May 2011,the City of Renton completed a ROD in accordance with the National Environmental Policy Act,and adopted a Planned Action Ordinance in accordance with the State Environmental Policy Act. The ROD and Planned Action Ordinance identified mitigation measures from the FEIS. The Record of Decision (ROD) concluded that."[w]ith the application of City-adopted development regulations and recommended mitigation measures,' and application of other federal and state requirements, no significant unavoidable adverse impacts are anticipated. Pursuant to 40 CFR 1505.3, this decision to proceed with Sunset Terrace and actions in the broader area will be implemented 'and mitigation measures imposed'through appropriate conditions in any land use or related permits or approvals issued by the City of Renton and through conditions of federal funding." This Reevaluation and Addendum maintains the mitigation measures from the EIS, ROD and Planned Action and identifies where the application of such mitigation measures (e.g., design guidelines) is particularly relevant and could be included in permit conditions. The.City finds by this re-evaluation, after considering the effects of the revised Master Plan, as well as existing and supplemental environmental documentation, that no substantive change to the findings in the ROD would occur.The Sunset Area Community Planned Action NEPA/SEPA EIS adequately examines the impacts of the overall project, and the proposed changes in the Master Plan would not result in modification to those.conclusions. No new or significantly different impacts to the environment would occur. Mitigation measures incorporated in the proposal and identified in the EIS, and additional consultation and mitigation documented in the ROD, represent reasonable steps to reduce adverse _ environmental effects of the proposed project. Together, these measures and would reduce effects to December 2015 29 RENTON S' ET COMMUNITY AREA REEVALUM ION AND ADDENDUM acceptable levels. No additional mitigation is warranted as a result of changes proposed in the Master Plan.

Detached single-family development':Two (2)significant trees8 for every five thousand (5,000) sq. ft. of lot area. For example, a lot with 9,600 square feet and a detached single-family house is required to have four(4) significant trees or their equivalent in caliper inches(one or more trees with a combined diameter of 24"). This is determined with the following formula: • Lot Area 1 x 2 = Minimum Number of Trees 5,000sq.ft.J Multi-family development(attached dwellings): Four(4)significant trees8 for every five thousand (5,000) sq. ft. of lot area.

Project• Assignment and Methodology This report documents an arborist's assessment of 2I trees on the above property per City of Renton Conditional Use Permit Submittal Requirements. Data was collected on August I I. Attached to this report'are thelfollowing: List of Trees with tree data, specific observations and recommendations Survey map with'numbers showing tree locations. The scope of work included a detailed assessment of the canopy form, foliage color and density, visible wounds and cavities, and other observable issues that may affect preservation and design decisions.TI a trees were inspected from all sides of the trunk while standing on the ground and were not probed during the assesment.The assessment consisted of the following steps: Trunk diameter was measured at 54"above the ground (DBH, Diameter at Breast Height) except in the case of trees with multiple trunks emerging at grade. If multiple leaders emerge at grade, individual leaders were measured at 4.5 feet above grade. If there is a single trunk under the crotch at or below 4.5 feet,then the single trunk was measured below the crotch. Observations of visible characteristics leading to conclusions about health.Tree condition was given a range from poor (P)to fair (F)to good (.G) to excellent(E). Identification was to species unless impossible to identify to that level without flowers and/or fruit. Concerns were noted on(structural defects including but not limited to decay, poor crown confirmation, co-dominant stems, dieback, dead wood, and fungal conks. Trees were given metal number tags to aid in communication.Tree numbers are listed on the attached List of Trees. Tree numbers are placed on the attached site map.The four Landmark Trees are identified on the map with "LM" placed next to them. The following conclusions and findings are based upon a site visit, current arboricultural best management practices, and my education and professional knowledge gained during 34 years of tree and landscape management in the Puget Sound area. Observations and General Recommendations Red,oak#6I, and Douglas firs#71 and 72 meet the City of Renton's size and health requirements to be considered Landmark Trees. These are the#1, priority for preservation. In addition,the seven oaks, numbered 60 to 66, are considered a grove with one continuous RFCF4310SunnysideAvenueN. 206-545.1726 v' I no Seattle,,Seattle,WA 98103-7661 206.280•9740 cell susammnicol@grilail•com JAN 2 6 2016 -- PLANNING DIVISION canopy.Trees 61 to 66 are mature, magnificent, healthy, and a real asset to the City of Renton's tree canopy. I highly recommend that all efforts be made to preserve them as a grove. In short, Landmark Trees#6I, 71, and 72, and the rest of the oaks are the highest priority for. preservation.Though the 34 inch diameter of Cottonwood #56 gives it Landmark Tree status, its preservation value is much reduced if it is over a structure, parking lot, or walkway where people are likely to frequent. This is due to the species' propensity for sudden limb drop at all times of the year. If a choice has to be made between preserving the cottonwoods or preserving the oaks, I recommend the oaks. Two young deciduous trees,#59 green ash and#60 red oak,are small enough to be moved with a tree spade if they cannot be preserved in place. The rest of the existing trees on this property have lesser preservation value. Several are reasonably healthy so preserve them if possible. Limits of Disturbance Tree protection fence locations shall be determined in either of two ways-- Drip Line Radius DLR) or Critical Root Zone (CRZ) based on trunk diameter. DLR was based on the distance from the center of the trunk to an average of the farthest branch tips.'CRZ was based on one foot of distance for every inch of trunk diameter at 4.5 feet above grade.Tree protection fencing shall be located using either the DLR or CRZ,whichever is reasonable given placement of future hardscape and structures. I have provided both on the attached List of Trees. Supplemental Trees Additional landscaping should include a variety of tree genera and species. I suggest using the City's Approved Street Tree List for suggestions. It is located at the link below: https://rentonwa.gov/uploadedFiles/Business/CED/FORMS/treeslist_march20 10.pdf Here are additional recommendations: Do not plant Fraxinus species since the Emerald Ash Borer may arrive in the next decade and kill members of the genus. Do not plant birches since the Bronze Birch Borer is currently killing birches in western Washington. Plant few maples, since this genus is now over-used locally. Plant a mix of deciduous and coniferous trees. Avoid using hemlocks, redbuds, poplars,willows, and alders. Planting and Maintenance Specifications Tree planting specifications shall conform to those recommended by the Urban Tree Foundation,found at this link: http://www.urbantree.org/details specs.shtml Tree maintenance specifications shall conform to best management practices as written in the International Society of Arboriculture's Best Management Practices booklets for pruning, soil management,tree and shrub fertilization, integrated pest management,watering,etc. 2 Tree Protection,Measures (to,be placed on Tree Protection or Site Plan) A Tree Protection Zone will be established for all trees to be preserved, and no grading, site work, or storage of materials or equipment shall be allowed within this zone. All herbicides used around and under paving shall be labeled as safe for use near trees. Prior to the start of construction,the consulting arborist shall meet with the contractor to review the location of tree protection fencing and work procedures. All trees to be retained shall be fenced to completely enclose the tree protection zone prior.to work starting on the site. Fencing shall meet requirements as written in 4-4- 130, Tree Retention and Land Use Clearing Regulations:"Six foot(6') high chain link temporary construction..1" Fencing shall be placed at the edge of the tree protection zone. Fences are to remain until all grading and construction is completed. Understory trees and shrubs shall be retained within the protection zone.These plants contribute to the root health of the retained trees. If contractor wishes to clear out debris, place equipment outside the drip line and reach in to scrape the surface.Avoid ' excavating beneath tree canopies. No grading, construction, demolition, or other work shall occur within the tree protection zone. Modifications to this zone must be approved in advance by the Consulting Arborist and/or City of Renton. Roots encountered during excavation shall be severed cleanly with lopper or saw,which should be on site for the duration of construction. Injuries occurring to any tree shall be immediately evaluated by the Consulting Arborist to determine appropriateitreatment methods. Pruning needed for clearance during construction shall be performed by a Certified Arborist, or under the di iection of a Certified Arborist. Long-term maintenance of preserved trees shall be as required by the City of Renton but shall include deep but'infrequent watering and pruning to remove-dead and cracked branches. 1 Assumptions and Limiting Conditions: 1. Field examination of the site was made on August I I, 2015. Observations and conclusions'are as of that date. 2. Care has been taken to obtain all information from reliable sources.All data has been verified insofar as possible; however, the consultant can neither guarantee nor be responsible for the accuracy of information provided by others. 3. There is no warranty or guarantee, expressed or implied, that problems or deficiencies, ofthe subject trees may not arise in the future.All trees possess the risk of failure.

Management Summary This report describes a cultural resources assessment of six tax parcels for the proposed Sunset Court Apartments in Renton, King County, Washington. The project is to construct a new mixed-income apartment complex as part of a redevelopment effort for the Renton Housing Authority's Sunset Terrace housing project. This assessment was developed to identify any previously'recorded archaeological or historic sites at the project location and evaluate the potential for the project to affect cultural resources.No previously recorded archaeological sites are located in or adjacent to the project boundary.Assessment did not identify significant potential for archaeological resources that could be affected by this project. Four-structures built over 50 years ago are located on four of the subject parcels, and were inventoried for inclusion on the Washington State Historic Preservation Office database. These buildings do not appear to meet eligibility criteria for state or national historic register eligibility. 1. Administrative Data Report Title: Cultural Resources Assessment for the Sunset Court Apartments Project, Seattle, Washington. \ Author: James Schumacher • r Report Date: October 23, 2015 Location: The project is located in a mixed urban residential/retail neighborhood in Renton, in Township 23 North,Range 5 East,'Section 9, Willamette Meridian(Figure 1). The subject property includes King County Tax Parcel numbers (and situs addresses) are: 722780-1660 1144 Harrington Avenue NE); 722780-1665 (1156 Glennwood Avenue NE);722780-1780 vacant lot on Harrington Place NE); and, 722780-1781 (City park on Harrington Place NE). Two adjacent"node"parcels included in this project are 722780-1315 (1062 Glennwood Avenue NE) and 722780-1290 (1081 Harrington Avenue NE). USGS 7.5' Topographic Map(s): Mercer-Island, WA Total Area Involved: Less than two acres. Objective (Research Design): This assessment was developed as a component of preconstruction environmental review with the goal of ensuring that no cultural resources are disturbed during construction of the proposed project by determining the potential for any as-yet unrecorded archaeological or historic sites within the project area. This project requires oversight from the U.S.Department of Housing and Urban Development. CRC's work was intended, in part,to assist in addressing federal agency responsibilities regarding the identification of potential impacts to archaeological and historic sites•in compliance with Section 106 of the National Historic Preservation Act(NHPA), as well as state laws and regulations protecting cultural resources (e.g., RCW 27.44, RCW 27.53). Under Section 106, agencies involved in a federal undertaking must take into account the undertaking's potential effects to historic properties (36 CFR 800.16(1)(1)). The Washington State Archaeological Sites and Resources Act. CRC Technical Memorandum 1507F-3 Sunset Court Apartments Project,,Renton, King County,WA Page 1 RCW 27.53)prohibits knowingly disturbing archaeological sites without a permif'from the Washington Department of Archaeology and Historic Preservation (DAHP), and the Indian Graves and Records Act(RCW 27.44)prohibits knowingly disturbing,Native American or historic graves. Assessment methods consisted of review of available project information, local environmental, cultural, and historical information, and records on file at DAHP, as well as field investigations. CRC also contacted cultural resources specialists with the Duwamish Tribe,the Muckleshoot Tribe, and the Snoqualmie Nation to inquire about project-related cultural information or concerns (Attachment B). This assessment utilized a research design that considered previous studies,the magnitude and nature of the project,the nature and extent of potential effects on historic properties, and the'likely nature and location of historic properties within the project area, as well as other applicable laws, standards, and guidelines(per 36CFR800.4 (b)(1)). National Register of Historic Places (NRHP) assessment criteria were developed by the National Park Service (NPS 1991). Cultural resources may qualify for NRHP listing if they: A. Are associated with events that have made a significant contribution to the broad patterns of our history; or B. Are associated with the lives of persons significant in our past; or C. Embody the distinctive characteristics of a type,period,or method of construction or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or D. Have yielded, or may be likely to yield, information important in prehistory or history. Upon meeting eligibility criteria, a cultural resource will be termed a"historic property"under the NHPA. According to the NRHP guidelines,the "essential physical features" of a historic property must be intact for it to convey its significance, and the resource must retain its integrity, or"the ability of a property to convey its significance." The seven aspects of integrity are: Location(the place where the historic property was constructed or the place where the historic event occurred); Design(the combination of elements that create the form,plan, space, structure, and style of a property); Setting(the physical environment of a historic property); Materials(the physical elements that were combined or deposited during a particular period of time and in a particular pattern or configuration to form a historic property); Workmanship(the physical evidence of the crafts of a particular culture or people during any given period of history or prehistory); Feeling(a property's expression of the aesthetic or historic sense of'a particular period of time), and; Association (the direct link between an important historic event or person and a historic property). CRC Technical Memorandum 1507F-3 Sunset Court Apartments Project, Renton, King County,WA Page 2 n Criteria used for assessment of potential eligibility for the Washington Heritage Register are similar to NRHP criteria(OAHP n.d.). Criteria to qualify include: Age of at least 50 years. If newer,the resource should have documented exceptional significance. The resource should have a!high to medium level of integrity. The resource should have documented historical significance at the local or state level. In order to be recommended underiCriterion A of the NRHP;properties must have an important association with historical themes in the region in the;late nineteenth and early twentieth century. Such themes might include the development of timber,mining, hydroelectric or other industry; historic Native American,European-American, or other ethnic group settlement, homesteading, or farmsteading;transportation infrastructure; and recreation or tourism. Eligibility under Criterion B requires that the property have a documented association with a prominent individual important to local,regional, state or national history. The property must be associated with the individual's productive life; ownership alone is not sufficient for a recommendation. In order to be recommended eligible under Criterion C, a structure must embody the distinctive characteristics of a type,period, orlmethod of construction and have documented historic association. The distinctive physical characteristics of the construction method must be present and reflect their historic significane. Interiors should be considered in assessing the property's ability to convey its historic character. Individual buildings within a complex of associated structures may retain integrity and be individually eligible. Eligibility under Criterion D requires a documented historic association and integrity of location, in order to have the potential to yield important information pertaining to historic themes. Properties must demonstrate the likelihood that they contain unique archaeological data important in answering one or more developed research questions. Recorded Cultural Resources Present: Yes [x] No [ No archaeological sites have been previously recorded in the project location. Three of the subject parcels each has a building that was inventoried with DAHP in 2011, but which was not evaluated. Project Background: Berk Consulting, on behalf of the City of Renton, requested Cultural Resource Consultants, Inc. (CRC)to conduct a cultural resources assessment prior to development of the Sunset Court Apartments in Renton, King County, Washington. The City of Renton is redeveloping the Sunset Terrace public housing community in northeast Renton. In 2011,the City completed an Environmental Impact Statement(EIS) and a Record of Decision in accordance with the National Environmental Policy Act(NEPA)and adopted a Planned Action Ordinance in accordance with the State Environmental Policy Act(SEPA) for redevelopment. The NEPA/SEPA Final Environmental Impact Statement supporting both milestones was issued that year. Since the original FEIS analysis,additional planning has occurred and changes are now proposed. As a result of potential changes,the City is preparing a revised Master Site Plan. CRC Technical Memorandum 1507F-3 Sunset Court Apartments Project, Renton, King County,WA Page 3 The proposed Sunset Court Apartment project will construct a new mixed-income apartment complex as part of the redevelopment effort.In 2011,the Sunset Court Apartment concept was considered as a"swap site"within this larger project,whereby an existing park and parcels would be consolidated for a larger park,to allow construction of affordable replacement housing. RHA has since acquired additional lots adjacent to the park to make the overall design more conducive to their plans. Two "node" lots located across the street would likely receive a share of housing units. The recently acquired lots are now included to expand a previously defined Area of Potential Effect(APE)for the Sunset Terrace housing project. This CRC report is to be included in the City of Renton Sunset Court NEPA,Re-Evaluation and SEPA Addendum,which is currently being prepared. The City of Renton and Renton,Housing Authority (RHA) considered the larger area around the current proposed Sunset Court Apartments in the 2011 Renton Sunset Area Environmental Impact Statement. Cultural resources were evaluated on the Master Plan Sites and swap sites in 2010 and 2011 (Elder et al. 2010; Stevenson-et al. 2011),which included archaeological assessment and historic property inventory; on numerous parcels surrounding the six parcels discussed in-this report(Figure 2). The proposed Sunset Court Apartments will be a 50 unit multi-family housing project situated on four tax parcels (Figure 3). Tax parcel numbers (andsitus addresses) are: 722780-1660 (1144 Harrington Avenue NE); 722780-1665 (1156 Glennwood Avenue NE); 722780-1780 (vacant lot on Harrington Place NE); and, 722780-1781 (City park on Harrington Place NE). Two adjacent node"parcels included in this project are 722780-1315 (1062 Glennwood Avenue NE) and 722780-1290 (1081 Harrington Avenue NE), located across Harrington Avenue NE from the other parcels. Eight townhomes are planned on the two node parcels, part of a coordinated development that would have another eight townhomes on two abutting sites in the original 2010 APE, for a total of 16 townhomes. Four•of the parcels contain one-story duplex residences that would be demolished. For purposes of this assessment,the area of potential effects (APE)for this project is understood to be the parcels described above and depicted on attached maps. 2. Background Research Background research was conducted in August-September 2015. Archival Sources Checked: DAHP WISAARD x] Three buildings over 50 years old have been inventoried within the project boundary. Web Soil Survey x] Soils mapped in the project location consist of Arents, Alderwood material, 6-15 percent slopes, and Ragnar-Indianola association, sloping(USDA NRCS 2015). Library x] Various historical, archaeological, and ethnographic references. General Land Office Map [x] 1865 Context Overview: Environmental and cultural context information for this project is derived from relevant published reports, articles, and books; historical maps and documents; geological and soils surveys; ethnographic accounts; and local archaeological survey reports. CRC Technical Memorandum 1507F-3 Sunset Court Apartments Project, Renton, King County,WA Page 4 4 P Elder et al. (2010)produced a detailed cultural resources and historical context statement for the RHA Sunset Terrace redevelopment project that included and expanded on information summarized in this report. Environmental Context: An understanding of environmental and geological processes is important to assess archaeological 'expectations and model the potential for unidentified cultural resources in any location. Local topography in the project area was formed by Late Pleistocene glaciers that advanced through the'area approximately 15,000 years ago, during the Vashon Stade of the Fraser Glaciation, scouring troughs or channels in the older glacial till that was deposited and compacted during p ievious glacial advances. Since the last glacial retreat(ca. 12,000-13,000 years ago), little, if any, sedimentary deposition has occurred in the vicinity of the project area. The surface"geologic unit mapped in the project location is Qgd: Pleistocene glacial drift, which is composed of unsorted till and outwash clay, silt, sand, gravel, and cobbles deposited by glacial ice (WA DNR 2015). Soils mapped in the project area are mostly AmC: Arents,Alderwood material, 6-15 percent slopes, and RdC: Ragnar-Indianola association, sloping, in the southwestern-most part of the.APE(USDA NRCS 2015). Arents developed from glacial till;the typical vertical profile consists of gravelly sandy loam,with the gravel fraction increasing with depth. Ragnar-Indianola soil was formed from glacial till;the typical profile consists of ashy fine sandy loam to 27-inches depth, over loamy sand. Evidence of postglacial cultural activity would typically be expected toibe present near the modern ground surface."If archaeological deposits were present within the project area,they would have been on the surface or f ery shallowly buried. Due to minimal post-glacial soil development, any present deposits would likely have been obscured or destroyed by natural erosional forces and historic development.Thus,this type of depositional environment is considered to have a low potential to contain intact archaeological deposits. Archaeological Context: Approximately 11,500 years of human occupation in the Puget Sound region have been summarized in many archaeological, ethnographic, and historic investigations conducted over the past several decades. Sites dated between roughly 5,000-2,500 years ago show evidence of increased human use of open prairie land,the saltwater littoral, and riverine environments and floodplains. Seasonal camps in both upland and lowland environments indicate specialized resource utilization that complimented long-term lowland villages (e.g., Larson and Lewarch 1995). By the mind-19th century and the period of intensive Euroamerican contact,the archaeological record shows evidence of changes in social and cultural traditions. Several previous cultural resource studies and overviews provide general background information applicable to the project area(e.g., Elder et al. 2010;Nelson 1990). Archaeological evidence dated to.between 3000-200 B.P. illustrates the beginning of the elaboration ofseasonal logistical mobility and patterns of seasonal residence that characterized the ethnographic pattern in the Puget Sound region. Sites dating to this period represent seasonal specialized spring and summer fishing and root gathering campsites, and village locations. Beginning approximately two hundred years ago,relatively rapid social changes occurred under the pressures of acculturation (Marino 1990; Suttles and Lane 1990). CRC Technical Memorandum 1507F-3 Sunset Court Apartments Project, Renton, King County,WA Page 5 Ethnographic Context: This region is within the traditional territory of the Duwamish Tribe of Southern Lushootseed speakers; historically, ancestors of members of the Snoqualmie Nation and Muckleshoot Tribe and other tribal groups may have utilized this general area Suttles and Lane 1990; Waterman 2001). Local Indian people shared many broadly defined traditions with their inland Puget Sound neighbors, including littoral, lacustrine, or riverine settlement patterns, subsistence emphasis on salmon and other fish, land game, and a wide variety of abundant vegetable foods, and household and village communities.linked by family and exchange relations (Suttles and Lane 1990). From the early twentieth century, ethnographers (e.g., Waterman 2001)recorded many traditional place names in the general area, as told to them by Native American informants; most of these place names are near the lake and river shorelines. One name is recorded as within the general upland vicinity or the project(Waterman's map is not exacting): T" gwi't is,which is translated as"'red face,' for a high bluff east of Renton" (Waterman 2001:148-149). Historic Context: Euro-American settlement began in the Renton area around 1850. By the mid-1850s, increased Euro-American settlement had drastically impacted Indian people and their traditions through disease, violence, and the disruption of settlements and subsistence economies. In 1855,the Duwamish and other Puget Sound tribes signed the Point Elliot Treaty,which forced local Indian people onto reservations. Coal deposits in the Renton area attracted prospectors to the area. By the 1870s, investors expanded the industry; these included William Renton of the Port Blakely Mill Company,who was cofounder of the Renton Coal Company (Kirk and Alexander 1990). To support the increase in demand for coal, railroads were built from Elliot Bay to Renton, and from Elliott Bay, coal was shipped to west coast markets. By the 1880s in the project area,the logging industry also figured prominently in economic activity in the greater Renton area Slauson 1976). The project area was a small part of a vast territory that the United States deeded to the Northern Pacific Railroad Company in 1894-1895 (BLM 2015). The Renton coal mines began to close by the 1890s; however,the city's location on a transportation corridor continued to stimulate industrial, commercial, and residential development(Kirk and Alexander 1990). Sunset Highway was developed south of the project APE by1910,and until 1940 was the main road between Seattle and Snoqualmie Pass (Buerge 1989). In 1940, establishment of the Boeing Company aircraft manufacturing plant brought greater industrial prosperity. By 1942 and the entry of the United States into,the Second World War,Boeing employed over 40,000 people. Until about this time, when demand for worker housing skyrocketed,the project APE retained its rural character. Many,Renton neighborhoods were established during the war years..Following the end of the war,the federal government aided Renton's construction of housing`projects and residential infrastructure,which included the Highlands north and south of Sunset Highway Buerge 1989). Historical Maps: The General Land Office(GLO) cadastral survey plat for the project area is blank; it does not show any natural or cultural features, such as streams, forests, structures; trails, or clearings at the project location or within at least 0.5-mile of the project APE (USSG 1865). The nearest feature illustrated on that map is a trail that ran from the southwest to the CRC Technical Memorandum 1507F-3 Sunset Court Apartments Project, Renton, King County,WA Page 6 northwest over 0.5-mile southeast of the APE. A late 19th-century King County township map depicts no natural or cultural features in the vicinity of the project APE(Anderson 1889). Maps produced by the Kroll Map Company (Kroll 1912, 1926, 1930)were reviewed; these show no mapped roads or features within the vicinity of the project APE, and indicate ownership of lands surrounding the APE as"Alex B. Stewart."A later(post-World War 2) edition of the map depicts platted roads that exist today (Kroll 1946). Recorded Cultural Resources: Single structures on three of the subject parcels were indexed with a historic property inventory form(HPI),based on Assessor computer records imported by the DAHP into that office's electronic WISAARD database in 2011. There are no archaeological sites in the vicinity of the project APE recorded with DAHP or with the King County Historic Preservation office (personal communication with Phil LeTourneau, King County Historic Preservation Program, September 1, 2015). The nearest recorded archaeological site (45KI786) consists of early 20th century human remains and coffin hardware found in a construction trench about one mile north of the current project APE (Rooke 2008). Multiple pre-contact and historic archaeological sites are recorded on the Cedar River floodplain, over one mile southwest of the APE.Literature review did not identify traditional cultural properties (TCPs) in or near the project. The nearest previous cultural resources assessments were conducted adjacent to the current project APE, both for the Sunset Terrace housing redevelopment(Elder et al. 2010; Stevenson et al. 2011). The first of these resulted in inventory of historic buildings, and"very low potential" for the presence of undisturbed archaeological deposits across nearly all of the study area(Elder et al. 2010:7-1). Forty-eight properties identified as 45 years of age or older were evaluated for NRHP-eligibility. Based on NRHP criteria, only one of these was recommended eligible, located at 2825 NE Sunset Boulevard and used at that time as a St. Vincent de Paul Superstore. The other 47 properties were recommended not eligible for the NRHP, due mostly to structural modifications and upgrades completed by RHA that compromised their historical integrity(Elder et al. 2010:2-6, 2-7). The DAHP concurred with these recommendations (Holter 2010). The second study adjacent to the current project parcels,which included excavation of shovel probes on one of these parcels,the City park(Figure 4), concluded the study area contained mixed or imported sediments or soils that would not have the potential to contain archaeological resources. The potential for the discovery of archaeological deposits with in the APE is considered very low"(Stevenson et al. 2011:7-1). All probes were negative for identification of archaeological resources. Survey for a cell antenna upgrade within one-half mile east of the APE inventoried historic buildings, but did not result in identification of archaeological sites (Buehner 2013). Survey for a fiber-optic installation along the I-405 corridor, about 0.80-mile west of the project APE, did not identify unrecorded cultural resources (Juell 2001). Survey for public housing improvements about 0.5-mile north of the APE resulted in inventory of two historic buildings; no archaeology was found(Hetzel and Elder 2010). CRC Technical Memorandum 1507F-3 Sunset Court Apartments Project, Renton, King County,WA Page 7 Archaeological Expectations:The DAHP statewide predictive model uses environmental data about the locations of known archaeological sites to identify where previously unknown archaeological sites are more likely to be found. The model correlates locations of known archaeological to environmental data"to determine the probability that, under a particular set of environmental conditions, another location would be expected to contain an archaeological site Kauhi and Markert 2009:2-3). Environmental data categories included in the computer-based model are elevation, slope, aspect, distance to water, geology, soils, and landforms. The model classifies different parts of the project area as low, moderate, and high potential,likely based on slope and distance to water(i.e., streams)variables. Based on native environmental factors,the DAHP model designates the project area as high probability for the presence of archaeological sites; however, based upon the results of background research and the evidence of historic and modern development,the specific project location is considered to have a low potential to contain intact archaeological deposits. Local geomorphology,the shallow depositional environment, and significant historic and modern urban ground disturbances make it unlikely that the project could encounter intact, significant archaeological deposits. 3. Fieldwork Field investigations were conducted by the author; notes and photographs are on file at CRC. Total Area Examined: The entire project area. Areas not examined: None. Date(s) of Survey: September 3,2015 Weather and Surface Visibility: Weather conditions were warm and dry. Surface visibility of mineral soils was obscured by buildings, sidewalks,and grass. 4. Results The author surveyed the project area in clear and dry weather(Figure 5). Various data sets suggested a very low potential for the presence of buried archaeology. These included geological data that indicated any post-Pleistocene archaeology would be buried at a very shallow depth and the history of significant ground disturbance due to mid-20`h century development across the project area. Two shovel probes were dug and sediments screenedrthrough 0.25-inch mesh Table 1). Soils appeared to be glacial till and fill.No artifacts or indication of buried surfaces or pre-modern anthropogenic sediments was found. The exteriors of the four duplex houses in the APE were accessible for inventory. County assessor information indicated these had all been built in 1943, during expansion of Renton's residential neighborhoods. These buildings were similar in appearance. Each was a one-story wood-frame residential duplex with a rectangular plan and medium-pitch side gable roof.

These extriors had been modified from their original construction, and appeared in generally fair to poor condition (Figure 6). Other than the association with Renton's wartime growth, no evidence was identified that would support eligibility of these buildings for state or federal historic registers. The historic physical character of the buildings was likely compromised by structural modifications one or more times, including changes to windows and roofs observed in the site reconnaissance. Cultural Resources Identified: Assessment of the project APE identified four buildings older than 50 years; excavation of'shovel probes suggested a very low potential for buried archaeology (Figure 7). The four structures were photographed and inventoried on WADAHP Historic Property Inventory forms.These forms are amended to this report and uploaded electronically to the DAHP Historic Property Inventory database.No pre-contact or potentially significant historic sites were identified in the project area. Conclusions,Findings and Recommendations:Pedestrian surbey, shovel probes, and background research did not identify evidence of precontact or potentially significant historic sites within the project APE. The four duplex residences appeared to have exterior window and roof modifications similar to those that RHA implemented to nearby buildings inventoried in 2010 (e.g., 1052 Glennwood Avenue NE)that were determined not eligible for the NRHP (Elder , 2010; Holter 2010). The four duplex residences are recommended not eligible for the NRHP. Under NRHP eligibility Criterion A,they are related to an event that made a significant contribution to the broad patterns of our history: the growth of Renton during the Second World War and its connection to Boeing's military aircraft production. However,this relationship is tangential and supported only by the construction year of 1943.As to Criterion B_, no evidence was identified for association with significant persons. The duplexes do not embody distinctive physical characteristics, and, as the surrounding neighborhood has undergone rebuilding and redevelopment since their construction,these do not represent a distinguishable entity whose components may lack individual distinction, as required by Criterion C. Under Criterion D,the duplexes are not likely to yield information important in history. Eligibility for the Washington Heritage Register is supported by the buildings' age of at least 50 years, but they each have a compromised level of integrity and do not have documented historical significance at the local or state level. The depositional environment and modern land use conditions suggest a very low potential for. • intact buried cultural deposits.

The work site will be secured from any additional impacts and the supervisor will be informed.j The project proponent will immediately contact the agencies with jurisdiction over the lands where the discovery is located, if appropriate. The appropriate agency archaeologist or the proponent's contracting archaeologist will determine the size of the work stoppage zone or discovery location in order to sufficiently protect the resource until further decisions can be made regarding the work site. The project proponent will consult(with Washington State Department of Archaeology and Historic Preservation(WADAHP)regarding the evaluation of the discovery and the appropriate protection measures, if applicable.(Once the consultation has been completed, and if the site is determined to be NRHP-eligible,the project proponent will request written concurrence from the ' agency or tribe(s)that the protection and•mitigation measures have been fulfilled. Upon notification of concurrence from the appropriate parties,the project proponent will proceed with the project. Within six months after completion of the above steps,the project proponent will prepare a final written report of the discovery. The report will include a description of the contents of the • discovery, a summary of consultation, and a description of the treatment or mitigation measures. i Protocols for Discovery of Human Remains If human remains are found within;the project area,the project proponent, its contractors or permit-holders, the following actions will be taken, consistent with Washington State RCWs 68.50.645,27.44.055,and 68.60.055: If ground-disturbing activities encounter human skeletal remains during the course of construction then all activity will cease that may cause further disturbance to those remains. The area of the find will,be secured and protected from further disturbance; The project proponent will prepare a plan for securing and protecting exposed human remains and retain consultants to perform these services. The finding of human skeletal remains will be reported to the county medical examiner/coroner and local law enforcement in the most expeditious manner possible. The remains will not be touched,moved, or further disturbed. The county medical examiner/coroner will assume jurisdiction over the human skeletal remains and make a determination of whether those remains are forensic or non-forensic. If the county medical examiner/coroner determines the remains are non-forensic,then they will report that finding to WADAHP,which will then take jurisdiction over the remains. WADAHP will notify any appropriate cemeteries and all affected tribes of the find. The State Physical Anthropologist will make a determination of whether the remains are Indian or Non-Indian and report that finding to CRC Technical Memorandum 1507F-3 Sunset Court Apartments Project, Renton, King County,WA Page 19 any appropriate cemeteries and the affected tribes. WADAHP will then handle all consultation with the affected parties as to the future preservation, excavation, and disposition of the remains.

By 1942 and the entry of the United States into the Second World War,Boeing employed over 40,000 people(Buerge 1989).The exterior of the house was accessible for inventory Schumacher 2015).County assessor information indicated it was built in 1943,during the wartime expansion of Renton's residential neighborhoods. Highlands and North Highlands Much of the existing development in the Highlands is single family and duplex housing,with newer multiple family complexes near Sunset Boulevard N.E.to the north and N.E.4th Street to the south.The single family and duplex homes were originally built by the federal government as temporary housing for Boeing employees during World War II.As the time,the neighborhood was in King County.After the war, in 1946,the neighborhood was annexed to the City of Renton.The majority of these homes have endured and become Renton's main source of low income housing. [...]The housing to the north is dominated by small,duplex and single family structures.

' The scope of our services consisted of exploring site surface and subsurface conditions, and then developing this report to provide recommendations for general earthwork and design criteria for foundations, retaining walls, and stormwater infiltration. This work was authorized by your acceptance of our proposal dated August 11, 2015. The attached report contains a discussion of the study and our recommendations. Please contact us if there are any questions regarding this report, or for further assistance during the design and construction phases of this project. Respectfully submitted, GEOTECH CONSULTANTS, INC. Z0;00.2 ‘. 7q43H7 James H. Strange, P . Associate TRC/JHS: at zC I_: IT` FEB 01 ?a"3 CITY C 7 GEOTECH CONSULTANTS, INC. r GEOTECHNICAL ENGINEERING STUDY Proposed Housing Development 1144—1158 Harrington Avenue Northeast Renton,Washington This report presents the findings and recommendations of our geotechnical engineering study for the site of the proposed housing development to be located in Renton. Development of the property is in the planning stage, and detailed plans were not made available to us. We understand that the development will consist of approximately 50 units. The lowest level of the structures will be close to the existing ground surface. Infiltration of stormwater has been proposed for the project. If the scope of the project changes from what we have described above, we should be provided with revised plans in order to determine if modifications to the recommendations and conclusions of this report are warranted. SITE CONDITIONS SURFACE The Vicinity Map, Plate 1, illustrates the general location of the irregularly-shaped site in Renton. The site is bordered to the west by Harrington Avenue Northeast, to the east by Harrington Place Northeast, to the south by a multi-story condominium building, and to the north by three multi-family buildings. The ground surface within the site slopes very slightly down toward the south. The western portion of the site is developed with two, one-story duplexes and a few detached sheds. The duplex yards are vegetated with grass lawns and a few landscaping bushes and trees. Most of the eastern side of the site is a public park, with a few children's play structures. The area around those structures is surrounded by shredded bark, and the remainder of the park is grass lawn. The northeast corner of the site is undeveloped, and vegetated with field grass and a few mature deciduous trees. A concrete retaining wall is located along the south edge of the site. This wall has a height of about 2 to 4 feet, and faces a cut for the adjacent southern parking area. SUBSURFACE The subsurface conditions were explored by excavating 10 test pits and three hand-augered test holes at the approximate locations shown on the Site Exploration Plan, Plate 2. Our exploration program was based on the proposed construction, anticipated subsurface conditions and those encountered during exploration, and the scope of work outlined in our proposal. The test pits were excavated on August 25, 2015 with a rubber-tired backhoe. A geotechnical engineer from our staff observed the excavation process, logged the test pits, and obtained representative samples of the soil encountered. "Grab" samples of selected subsurface soil were collected from the backhoe bucket. The Test Pit Logs are attached to this report as Plates 3 through 7. The test holes were excavated on September 14, 2015 using hand tools. A geotechnical engineer from our staff conducted and logged the test holes. The Test Hole Logs are attached to this report as Plates 8 and 9. GEOTECH CONSULTANTS,INC. Renton Housing Authority JN 15342 October 15, 2015 Page 2 Soil Conditions The;test pits and test holes generally encountered about one foot of topsoil at the ground surface. Test Pit 10, located near the southwest corner of the site, revealed 1.5 feet of fill overlying topsoil. Test Hole 3, close to the play structures in the-southeast corner of the site, encountered shredded bark, geotextile, and gravel that extended to a depth of about 1.3 feet; no topsoil,was exposed by that exploration. Test Pit 6 was located between the park and Harrington Place Northeast, and revealed a few inches of gravel but no topsoil. Below the topsoil and the surface material described above, the explorations encountered sand with gravel that was loose to medium-dense. This sand extended to depths of 2 to 6 feet, and was medium-dense within about 3 feet of the ground surface. The sand with gravel extended to the greatest depths in the northeast third of the site. The sand with gravel was underlain 'by medium- dense to dense silty sand with gravel in the explorations, with the exception of those in which we completed infiltration testing, as described below. The silty sand with gravel has been glacially- overridden, has very low permeability, and is referred to as glacial till. Groundwater Conditions No groundwater seepage was observed in the test pits or test holes. It should-be noted that groundwater levels vary seasonally with rainfall and other factors. We anticipate that perched groundwater could be found above the silty sands encountered in our explorations, especially during the normally wet winter and spring months. The stratification lines on the logs represent the approximate boundaries between soil types at the exploration locations. The actual transition between soil types may be gradual, and subsurface conditions can vary between exploration locations. The logs provide specific subsurface information only at the locations tested. The relative densities and moisture descriptions indicated on the test pit logs are interpretive descriptions based on the conditions observed during excavation. The compaction of test pit backfill was not in the scope of our services. Loose soil will therefore be found in the area of the test pits. If this presents a problem, the backfill will need to be removed and replaced with structural fill during construction. INFILTRATION TESTING We conducted EPA falling head,infiltration testing at Test Pit 5 at a depth of 2.5 feet and in Test Hole 1 at a depth of 3 feet. As required by the City of Renton,the infiltration testing was completed in general accordance with the procedure outlined in the 2009 Surface Water Design Manual. The final measured infiltration rate at Test Pit 5 was 96 inches' per hour, and the measured rate at Test Hole 1 was 60 inches per hour. Impermeable silty sand/glacial till soil was encountered in our test holes at the following depths: Test Pit 1' ' 2 3 " 4 5* 6 •7 8 ' 9 10 Depth 2 3 5.5 6 2.5+ 6 5 3.5 3.5 4 " Test Hole 1*. 2 3 , Depth 3+ 3.8 2.5 Test Pit 5 and Test Hole 1 were infiltration holes and were not excavated to the glacial till. LABORATORY TESTING We obtained a sample from a depth of 2 feet in Test Pit 2 and provided that sample to an analytical laboratory. That facility determined that the Cation Exchange Capacity of the sample was 3.81 and the Total Organic Carbon was 0.528%. GEOTECH CONSULTANTS, INC. Renton Housing Authority JN 15342 October 15, 2015 Page 3 CONCLUSIONS AND RECOMMENDATIONS GENERAL THIS SECTION CONTAINS A SUMMARY OF OUR STUDY AND FINDINGS FOR THE PURPOSES OF A GENERAL OVERVIEW ONLY. MORE SPECIFIC RECOMMENDATIONS AND CONCLUSIONS ARE CONTAINED IN THE REMAINDER OF THIS REPORT ANY PARTY RELYING ON THIS REPORT SHOULD READ THE ENTIRE DOCUMENT The test pits conducted for this study encountered native, medium-dense soil within a few feet of the ground surface. Conventional footings bearing directly on that material will be appropriate for the structure foundations. The sand and gravel soils present below the surficial topsoil has high permeability, as our infiltration testing demonstrates, and stormwater infiltration in that material is feasible. However, the underlying dense glacial till soil has very low permeability and water will accumulate above it and develop a perched water condition. We expect that most surface water at the site in its current condition infiltrates through the topsoil and sandy soil, and is then essentially prevented from continuing to flow any deeper by glacial till. A proper, designed infiltration system will need to be extremely shallow to duplicate the current condition. As the 2009 Surface Water Design Manual requires, any infiltration system should introduce water at least 3 feet above the surface of the low-permeability silty sand/glacial till. Shallow permeable pavement could work in certain areas and depths at the site, but we recommend that any infiltration systems for concentrated flow (roof runoff) or excavated infiltration systems (drywells/trenches) be avoided as the clearance to the glacial till is not available in most areas of the site. Additionally, no infiltration system should be located within 75 feet of the retaining wall at the south edge of the property. In our opinion, a design infiltration rate of 2 inches per hour can be can be used for the permeable pavement infiltration. The erosion control measures needed during the site development will depend heavily on the weather conditions that are encountered. We anticipate that a silt fence will be needed around the downslope sides of any cleared areas. Existing pavements, ground cover, and landscaping should be left in place wherever possible to minimize the amount of exposed soil. Rocked staging areas and construction access roads should be provided to reduce the amount of soil or mud carried off the property by trucks and equipment. Wherever possible, the access roads should follow the alignment of planned pavements. Trucks should not be allowed to drive_off of the rock-covered areas. Cut slopes and soil stockpiles should be covered with plastic during wet weather. Following clearing or rough grading, it may be necessary to mulch or hydroseed bare areas that will not be immediately covered with landscaping or an impervious surface. On most construction projects, it is necessary to periodically maintain or modify temporary erosion control measures to address specific site and weather conditions. The drainage and/or waterproofing recommendations presented in this report are intended only to prevent active seepage from flowing through concrete walls or slabs. Even in the absence of active seepage into and beneath structures, water vapor can migrate through walls, slabs, and floors from the surrounding soil, and can even be transmitted from slabs and foundation walls due to the concrete curing process. Water vapor also results from occupant uses, such as cooking and bathing. Excessive water vapor trapped within structures can result in a variety of undesirable conditions, including, but not limited to, moisture problems with flooring systems, excessively moist air within occupied areas, and the growth of molds, fungi, and other biological organisms that may be harmful to the health of the occupants. The designer or architect must consider the potential vapor sources and likely occupant uses, and provide sufficient ventilation, either passive or mechanical,to prevent a build up of excessive water vapor within the planned structure. Geotech Consultants, Inc. should be allowed to review the final development plans to verify that the recommendations presented in this report are adequately addressed in the design. Such a plan review would be additional, work beyond the current scope of work for this study, and it may include revisions to our recommendations to accommodate site, development, and geotechnical constraints that become more evident during the review process. GEOTECH CONSULTANTS,INC. Renton Housing Authority JN 15342 October 15, 2015 Page 4 We recommend including this report, in its entirety, in the project contract documents. This report should also be provided to any future property owners so they will be aware of our findings and recommendations. SEISMIC CONSIDERATIONS In accordance with the International Building Code (IBC), the site soil profile within 100 feet of the ground surface is best represented by Site Class Type D (Stiff Site Class). As noted in the USGS website, the mapped spectral acceleration value for a 0.2 second (Ss) and 1.0 second period (Si) equals 1.43g and 0.54g, respectively. • The IBC states that a site-specific seismic study need not be performed provided that the peak ground acceleration be equal to Sos/2.5, where Sos is determined in ASCE 7. It is noted that Sos is equal to 2/3Sms. SMS equals Fa times Ss,where Fa is determined in Table 11.4-1. For our site, Fa = 1.0. The calculated peak ground acceleration that we utilized for the seismic-related parameters (earth pressures and seismic surcharges)of this report equals 0.38g. The site soils are not susceptible to seismic liquefaction because of their medium-dense to dense nature and the absence of near-surface groundwater. CONVENTIONAL FOUNDATIONS The proposed structure can be supported on conventional continuous and spread footings bearing on undisturbed, medium-dense, native soil. We recommend that continuous and individual spread footings have minimum widths of 12 and 16 inches, respectively. Exterior footings should also be bottomed at least 18 inches below the lowest adjacent finish ground surface for protection against frost and erosion. The local building codes should be reviewed to determine if different footing widths or embedment depths are required. Footing subgrades must be cleaned of loose or disturbed soil prior to pouring concrete. Depending upon site and equipment constraints,this may require removing the disturbed soil by hand. An allowable bearing pressure of 2,500 pounds per square foot (psf) is appropriate for footings supported on competent native soil. A one-third increase in this design bearing pressure may be used when considering short-term wind or seismic loads. For the above design criteria, it is anticipated that the total post-construction settlement of footings founded on competent native soil will be about one-inch, with differential settlements on the order of one-half-inch in a distance of 30 feet along a continuous footing with a uniform load. Lateral loads due to wind or seismic forces may be resisted by friction between the foundation and the bearing soil, or by passive earth pressure acting on the vertical, embedded portions of the foundation. For the latter condition, the foundation must be either poured directly against relatively level, undisturbed soil or be surrounded by level, well-compacted fill. We recommend using the following ultimate values for the foundation's resistance to lateral loading: PARAMETER ULTIMATE VALUE Coefficient of Friction 0.45 Passive Earth Pressure 350 pcf Where: pcf is Pounds per Cubic Foot, and Passive Earth Pressure is computed using the equivalent fluid density. If the ground in front of a foundation is loose or sloping, the passive earth pressure given above will not be appropriate. We recommend maintaining a safety factor of at least 1.5 for the foundation's resistance to lateral loading,when using the above ultimate values. GEOTECH CONSULTANTS,INC. Renton Housing Authority JN 15342 October 15, 2015 Page 5 FOUNDATION AND RETAINING WALLS Retaining walls backfilled on only one side should be designed to resist the lateral earth pressures imposed by the soil they retain. The following recommended parameters are for walls that restrain level backfill: PARAMETER VALUE Active Earth Pressure*35 pcf Passive Earth Pressure 350 pcf Coefficient of Friction 0.45 Soil Unit Weight 130 pcf Where: pcf is Pounds per Cubic Foot, and Active and Passive Earth Pressures are computed using the equivalent fluid pressures. For a restrained wall that cannot deflect at least 0.002 times its height,a uniform lateral pressure equal to 10 psf times the height of the wall should be added to the above active equivalent fluid pressure. The design values given above do not include the effects of any hydrostatic pressures behind the walls and assume that no surcharges, such as those caused by slopes, vehicles, or adjacent foundations will be exerted on the walls. If these conditions exist, those pressures should be added to the above lateral soil pressures. Where sloping backfill is desired behind the walls, we will need to be given the wall dimensions and the slope of the backfill in order to provide the appropriate design earth pressures. The surcharge due to traffic loads behind a wall can typically be accounted for by adding a uniform pressure equal to 2 feet multiplied by the above active fluid density. Heavy construction equipment should not be operated behind retaining and foundation walls within a distance equal to the height of a wall, unless the walls are designed for the additional lateral pressures resulting from the equipment. The values given above are to be used to design only permanent foundation and retaining walls that are to be backfilled, such as conventional walls constructed of reinforced concrete or masonry. It is not appropriate to use the above earth pressures and soil unit weight to back-calculate soil strength parameters for design of other types of retaining walls, such as soldier pile, reinforced earth, modular or soil nail walls. We can assist with design of these types of walls, if desired. The passive pressure given is appropriate only for a shear key poured directly against undisturbed native soil, or for the depth of level, well-compacted fill Placed in front of a retaining or foundation wall. The values for friction and passive resistance are ultimate values and do not include a safety factor. Restrained wall soil parameters should be utilized for a distance of 1.5 times the wall height from corners or bends in the walls. This is intended to reduce the amount of cracking that can occur where a wall is restrained by a corner. Wall Pressures Due to Seismic Forces - The surcharge wall loads that could be imposed by the design earthquake can be modeled by adding a uniform lateral pressure to the above-recommended active pressure. The recommended surcharge pressure is 8H pounds per square foot(psf),where H is the design retention height of the wall. Using this increased pressure, the safety factor against sliding and overturning can be reduced to 1.2 for,the seismic analysis. Retaining Wall Backfill and Waterproofing Backfill placed behind retaining or foundation walls should be coarse, free-draining structural fill containing no organics. This backfill should contain no more than 5 percent silt or clay particles land GEOTECH CONSULTANTS,INC. Renton Housing Authority JN 15342 October 15, 2015 Page 6 have no gravel greater than 4 inches in diameter. The percentage of particles passing the No.4 sieve should be between 25 and 70 percent. If the native sand or silty sand is used as backfill,a drainage composite similar to Miradrain 6000 should be placed against the backfilled retaining walls. The drainage composites should be hydraulically connected to the foundation drain system. Free-draining backfill or gravel should be used for the entire width of the backfill where seepage is encountered.)) For increased protection, drainage composites should be placed along cut slope faces, and-the walls should be backfilled entirely with free-draining soil. The later section entitled Drainage Considerations should also be reviewed for recommendations related to subsurface drainage behind foundation and retaining walls. The purpose of these backfill requirements is to ensure that the design criteria for a retaining wall are not exceeded because- of a build-up of hydrostatic pressure behind the wall. Also, subsurface drainage systems are not intended to handle large volumes of water from surface runoff. The top 12 to 18 inches of the backfill should consist of a compacted, relatively impermeable soil or topsoil, or the surface should be paved. The ground surface must alsorslope away from backfilled walls to reduce the potential for surface water to percolate into the backfill. Water percolating through pervious surfaces (pavers, gravel, permeable pavement, etc.) must also be prevented from flowing toward walls or into the backfill zone. The compacted subgrade below pervious surfaces and any associated drainage layer should therefore be sloped away. Alternatively, a membrane and subsurface collection system could be provided below a'pervious surface. It is critical that the wall backfill be placed in lifts and be properly compacted, in order for the above- recommended design earth pressures to be appropriate. The wall design criteria assume that the backfill will be well-compacted in lifts no thicker than 12 inches. The compaction of backfill near the walls_should be accomplished with hand-operated equipment to prevent the walls from being overloaded by the higher soil forces that occur during compaction. The section entitled General Earthwork and Structural Fill contains additional recommendations regarding the placement and compaction of structural fill behind'retaining and foundation walls. The above recommendations are not intended to waterproof below-grade walls, or to prevent the formation of mold, mildew or fungi in interior spaces. Over time, the performance of subsurface drainage systems can degrade, subsurface groundwater flow patterns can change, and utilities can break or develop leaks. Therefore, waterproofing should be provided where future seepage through the walls is not acceptable. This typically includes limiting cold joints and wall penetrations, and using bentonite panels or membranes on the outside of the walls. There are a variety of different waterproofing materials and systems, which should be installed by an experienced contractor familiar with the anticipated construction and subsurface conditions. Applying a thin coat of asphalt emulsion to the outside face of a wall is not considered waterproofing, and will only help to reduce moisture generated from water vapor or capillary action from seeping through the concrete. As with any project, adequate ventilation of basement and crawl space areas is important to prevent a build up of water vapor that is commonly transmitted through concrete walls from the surrounding soil, even when seepage is not present. This is appropriate even when waterproofing is applied to the outside of foundation and retaining walls. We recommend that you contact an experienced envelope consultant if detailed recommendations or specifications related to waterproofing design, or minimizing the potential for infestations of mold and mildew are desired. The General, Slabs-On-Grade, and Drainage Considerations sections should be reviewed for additional recommendations related to the control of groundwater and excess water vapor for the anticipated construction. SLABS-ON-GRADE The building floors can be constructed as slabs-on-grade atop competent native soil, or on structural fill. The subgrade soil must be in a firm, non-yielding condition at the,time of slab construction or underslab fill placement. Any soft areas encountered should be excavated and replaced with select, imported structural fill. GEOTECH CONSULTANTS,INC. Renton Housing Authority JN 15342 October 15, 2015 Page 7 Even where the exposed soils appear dry, water vapor will tend to naturally migrate upward through the soil to the new constructed space above it. This can affect moisture-sensitive flooring, cause imperfections or damage to the slab, or simply allow excessive water vapor into the space above the slab. All interior slabs-on- grade should be underlain by a capillary break drainage layer consisting of a minimum 4-inch thickness of clean gravel or crushed rock that has a fines content (percent passing the No. 200 sieve) of less than 3 percent and a sand content (percent passing the No. 4 sieve) of no more than 10 percent. Pea gravel or crushed rock are typically used for this layer. As noted by the American Concrete Institute (ACI) in the Guides for Concrete Floor and Slab Structures, proper moisture protection is desirable immediately below any on-grade slab that will be covered by tile,wood, carpet, impermeable floor coverings, or any moisture-sensitive equipment or products. ACI also notes that vapor retarders such as 6-mil plastic sheeting have been used in the past, but are now recommending a minimum 10-mil thickness for better durability and long term performance. A vapor retarder is defined as a material with a permeance of less than 0.3 perms, as determined by ASTM E 96. It is possible that concrete admixtures may meet this specification, although the manufacturers of the admixtures should be consulted. Where vapor retarders are used under slabs, their edges should overlap by at least 6 inches and be sealed with adhesive tape. The sheeting should extend to the foundation walls for maximum vapor protection. If no potential for vapor passage through the slab is desired, a vapor barrier should be used. A vapor barrier, as defined by ACI, is a product with a water transmission rate of 0.01 perms when tested in accordance with ASTM E 96. Reinforced membranes having sealed overlaps can meet this requirement. The General, Permanent Foundation and Retaining Walls, and Drainage Considerations sections should be reviewed for additional recommendations related to the control of groundwater and excess water vapor for the anticipated construction. EXCAVATIONS AND SLOPES Excavation slopes should not exceed the limits specified in local, state, and national government safety regulations. Temporary cuts to a depth of about 4 feet may be attempted vertically in unsaturated soil, if there are no indications of slope instability. However, vertical cuts should not be made near property boundaries, or existing utilities and structures. Based upon Washington Administrative Code (WAC) 296, Part N, the soil at the subject site would generally be classified as Type B. Therefore, temporary cut slopes greater than 4 feet in height should not be excavated at an inclination steeper than 1:1 (Horizontal:Vertical), extending continuously between the top and the bottom of a cut. The above-recommended temporary slope inclination is based on the conditions exposed in our explorations, and on what has been successful at other sites with similar soil conditions. It is possible that variations in soil and groundwater conditions will require modifications to the inclination at which temporary slopes can stand. Temporary cuts are those that will remain unsupported for a relatively short duration to allow for the construction of foundations, retaining walls, or utilities. Temporary cut slopes should be protected with plastic sheeting during wet weather. It is also important that surface runoff be directed away from the top of temporary slope cuts. Cut slopes should also be backfilled or retained as soon as possible to reduce the potential for instability. Please note that sand or loose soil can cave suddenly and without warning. Excavation, foundation, and utility contractors should be made especially aware of this potential danger. These recommendations may need to be modified if the area near the potential cuts has been disturbed in the past by utility installation, or if settlement-sensitive utilities are located nearby. All permanent cuts into native soil should be inclined no steeper than 2:1 (H:V). Water should not be allowed to flow uncontrolled over the top of any temporary or permanent slope. All permanently exposed slopes should be seeded with an appropriate species of vegetation to reduce erosion and improve the stability of the surficial layer of soil. GEOTECH CONSULTANTS,INC. 1 Renton Housing Authority JN 15342 October 15, 2015 Page 8 DRAINAGE CONSIDERATIONS Footing drains should be used where: (1) crawl spaces or basements will be below a structure; (2) a slab is below the outside grade; or, (3) the outside grade does not slope downward from a building. Drains should also be placed at the base of all earth-retaining walls. These drains should be surrounded by at least 6 inches of 1-inch-minus, washed rock that is encircled with non-woven, geotextile filter fabric (Mirafi 140N, Supac' 4NP, or similar material). At its highest point, a perforated pipe invert should be at least 6 inches below the bottom of a slab floor or the level of a crawl space. The discharge pipe for subsurface drains should be sloped for flow to the outlet point. Roof and surface water drains must not discharge into the foundation drain system. A typical drain detail is attached to this report as Plate 10. For the best long-term performance, perforated PVC pipe is recommended for all subsurface drains. As a minimum, a vapor retarder, as defined in the Slabs-On-Grade section, should be provided in any crawl space area to limit the transmission of water vapor from the underlying soils. Crawl space grades are sometimes left near the elevation of the bottom of the footings. As a result, an outlet drain is recommended for all crawl spaces to prevent an accumulation of any water that may bypass the footing drains. Providing even a few inches of free draining gravel underneath the vapor retarder limits the potential for seepage to build up on top of the vapor retarder. No groundwater was observed during our field work. If seepage is encountered in an excavation, it should be drained from the site by directing it through drainage ditches, perforated pipe, or French drains, or by pumping it from sumps interconnected by shallow connector trenches at the bottom of the excavation. The excavation and site should be graded so that surface water is directed off the site and away from the tops of slopes. Water should not be allowed to stand in any area where foundations, slabs, or pavements are to be constructed. Final site grading in areas adjacent to buildings should slope away at least 2 percent, except where the area is paved. Surface drains should be provided where necessary to prevent ponding of water behind foundation or retaining walls. A discussion of grading and drainage related to pervious surfaces near walls and structures is contained in the Foundation and Retaining Walls section PAVEMENT AREAS The pavement section may be supported on competent, native soil or on structural fill compacted to a 95 percent density. The pavement subgrade must be.in a stable, non-yielding condition at the time of paving. Granular structural fill or geotextile fabric may be needed to stabilize soft, wet, or unstable areas. To evaluate pavement subgrade strength, we recommend that a proof roll be completed with a loaded dump truck immediately before paving. In most instances where unstable subgrade conditions are encountered, an - additional 12 inches of granular structural fill will stabilize the subgrade, except for very soft areas where additional fill could be required. The subgrade should be evaluated by Geotech Consultants, Inc., after the,site is stripped and cut to grade. Recommendations for the compaction of structural fill beneath pavements are given in the section entitled General lEarthwork and Structural Fill. The performance of site pavements is directly related to the strength and stability of the underlying subgrade. The pavement for lightly loaded traffic and parking areas should consist of 2 inches of asphalt concrete (AC) over 4 inches of crushed rock base (CRB) or 3 inches of asphalt-treated base (ATB). We recommend providing heavily loaded areas with 3 inches of AC over 6 inches of CRB or 4 inches of ATB. Heavily loaded areas are typically main driveways, dumpster sites, or areas with truck traffic. Increased maintenance and more frequent repairs should be expected if thinner pavement sections are used. Water from planter areas and other sources should not-be allowed to infiltrate into the pavement subgrade. The pavement section recommendations and guidelines presented in this report are based on our experience in the area and,on what has been successful in similar situations. ((We can provide recommendations based on expected traffic loads and California Bearing Ratio (CBR) tests, if requested.)) As with any pavements, some maintenance and repair of limited areas can be expected as the pavement ages. Cracks in the pavement should be sealed as soon as possible after they become evident, in order to reduce the potential for GEOTECH CONSULTANTS,INC. Renton Housing Authority JN 15342 October 15, 2015 Page 9 degradation of the subgrade from infiltration of surface water. For the same reason, it is also prudent to seal the surface of the pavement after it has been in use for several years. To provide for a design without the need for any maintenance or repair would be uneconomical. GENERAL EARTHWORK AND STRUCTURAL FILL All building and pavement areas should be stripped of surface vegetation, topsoil, organic soil, and other deleterious material. It is important that existing foundations be removed before site development. The stripped or removed materials should not be mixed with any materials to be used as structural fill, but they could be used in non-structural areas, such as landscape beds. Structural fill is defined as any fill, including utility backfill, placed under, or close to, a building, behind permanent retaining or foundation walls, or in other areas where the underlying soil needs to support loads. All structural fill should be placed in horizontal lifts with a moisture content at, or near, the optimum moisture content. The optimum moisture content is that moisture content that results in the greatest compacted dry density. The moisture content of fill is very important and must be closely controlled during the filling and compaction process. The allowable thickness of the fill lift will depend on the material type selected, the compaction equipment used, and the number of passes made to compact the lift. The loose lift thickness should not exceed 12 inches. We recommend testing the fill as it is placed. If the fill is not sufficiently compacted, it can be recompacted before another lift is placed. This eliminates the need to remove the fill to achieve the required compaction. The following table presents recommended relative compactions for structural fill: LOCATION OF FILL MINIMUM RELATIVE PLACEMENT COMPACTION Beneath slabs or 95% walkwa s Filled slopes and behind 90% retainin• walls 95%for upper 12 inches of Beneath pavements subgrade; 90% below that level Where: Minimum Relative Compaction is the ratio,expressed in percentages, of the compacted dry density to the maximum dry density, as determined in accordance with ASTM Test Designation D 1557-91(Modified Proctor). Structural fill that will be placed in wet weather should consist of a coarse, granular soil with a silt or clay content of no more than 5 percent. The percentage of particles passing the No.200 sieve should be measured from that portion of soil passing the three-quarter-inch sieve. LIMITATIONS The conclusions and recommendations contained in this report are based on site conditions as they existed at the time of our exploration and assume that the soil and groundwater conditions encountered in the test pits .are representative of subsurface conditions on the site. If the subsurface conditions encountered during construction are significantly different from those observed in our explorations, we should be advised at once so that we can review these conditions and reconsider our recommendations where necessary. Unanticipated conditions are commonly encountered on construction sites and cannot be fully anticipated by merely taking samples in test GEOTECH CONSULTANTS,INC. r Renton Housing Authority JN 15342 October 15, 2015 Page 10 pits. Subsurface conditions can also vary between exploration locations. Such unexpected conditions frequently require making additional expenditures to attain a properly constructed project. It is recommended that the owner consider providing a contingency fund to accommodate such potential extra costs and risks. This is a standard recommendation for all projects. This report has been prepared for the exclusive use of Renton Housing Authority and its representatives for specific application to this project and site. Our conclusions and recommendations are professional opinions derived in accordance with our understanding of current local standards of practice and within the scope of our services. No warranty is expressed or implied. The scope of our services does not include services related to construction safety precautions, and our recommendations are not intended to direct the contractor's methods, techniques, sequences, or procedures, except as specifically described in our report for consideration in design. Our services also do not include assessing or minimizing the potential for biological hazards, such as mold, bacteria, mildew and fungi in either the existing or proposed site development. ADDITIONAL SERVICES Geotech Consultants, Inc. should be retained to provide geotechnical consultation, testing, and observation services during construction. This is to confirm that subsurface conditions are consistent with those indicated by our exploration, to evaluate whether earthwork and foundation construction activities comply with the general intent of the recommendations presented in this report, and to provide suggestions for design changes in the event subsurface conditions differ from those anticipated prior to the start of construction. However, our work would not include the supervision or direction of the actual work of the contractor and its employees or agents. Also, job and site safety, and dimensional measurements, will be the responsibility of the contractor. During the construction phase, we will provide geotechnical observation and testing services when requested by you or your representatives. Please be aware that we can only document site work we actually observe. It is still the responsibility of your contractor or on-site construction team to verify that our recommendations are being followed, whether we are present at the site or not. The scope of our work did not include an environmental assessment, but we can provide this service, if requested.
