FINDINGS OF FACT (FOF): 1. The Planning Division of the City of Renton accepted the above master application for review on August 8, 2018, and determined the application complete on August 15, 2018. The project complies with the 120-day review period. 2. The project site is located at 532 SW 3rd Pl. 3. The project site is currently developed with an existing single-family home proposed to be retained. 4. Access to proposed Lot A would continue to be provided via an existing residential driveway off of SW 3rd Place to the south. Access to proposed Lots B and C would be provided via an existing alley (SW 3rd Street) along the north property line and a 1,039 SF turnaround tract which extends off of the alley. 5. The property is located within the Residential Medium Density (MD) Comprehensive Plan land use designation. 6. The site is located within the Residential-8 (R-8) zoning classification. 7. There are approximately 29 trees located onsite of which the applicant is proposing to retain a total of 9 trees. 8. The site is mapped with high landslide hazards and protected slopes. 9. Currently, no grading activities are proposed for the site. Proposed lot grading will be evaluated at building permit submittal. 10. The applicant is proposing to begin construction following land use and construction permit approval. 11. Staff received two public comment letters (Exhibit 10). To address public comments the following report contains analysis related to tree retention. 12. Representatives from various city departments have reviewed the application materials to identify and address issues raised by the proposed development. These comments are contained in the official file, and the essence of the comments has been incorporated into the appropriate sections of this report and the Departmental Recommendation at the end of this report. 13. Comprehensive Plan Compliance: The site is designated Medium Density (MD) on the City’s Comprehensive Plan Map. The purpose of the MD designation is to allow a variety of single-family and multi-family development types, with continuity created through the application of design guidelines, the organization of roadways, sidewalks, public spaces, and the placement of community gathering places and civic amenities. The proposal is compliant with the following Comprehensive Plan Goals and Policies if all conditions of approval are met: Compliance Comprehensive Plan Analysis  Goal L-H: Plan for high-quality residential growth that supports transit by providing urban densities, promotes efficient land utilization, promotes good health and physical activity, builds social connections, and creates stable neighborhoods by incorporating both built amenities and natural features.  Goal L-I: Utilize multiple strategies to accommodate residential growth, including:  Development of new single-family neighborhoods on large tracts of land outside the City Center,  Development of new multi-family and mixed-use in the City Center and in the Residential High Density and Commercial Mixed Use designations, and DocuSign Envelope ID: F72C5D06-49BE-4814-BB99-20733D01C274 City of Renton Department of Community & Economic Development Sather Short Plat Administrative Report & Decision LUA18-000559 Report of October 30, 2018 Page 5 of 21 D_Admin Decision_Sather Short Plat_181030  Infill development on vacant and underutilized land in established neighborhoods and multi-family areas.  Policy L-29: Minimize erosion and sedimentation in and near sensitive areas by requiring appropriate construction techniques and resource practices, such as low impact development.  Policy L-37: Land uses in areas subject to flooding, seismic, geologic, and coal mine hazards should be designed to prevent property damage and environmental degradation before, during, and after construction.  Goal L-BB: Maintain a high quality of life as Renton grows by ensuring that new development is designed to be functional and attractive.  Goal L-FF: Strengthen the visual identity of Renton and its Community Planning Areas and neighborhoods through quality design and development. 14. Zoning Development Standard Compliance: The site is classified Residential-8 (R-8) on the City’s Zoning Map. Development in the R-8 Zone is intended to create opportunities for new single-family residential neighborhoods and to facilitate high-quality infill development that promotes reinvestment in existing single-family neighborhoods. It is intended to accommodate uses that are compatible with and support a high-quality residential environment and add to a sense of community. The proposal is compliant with the following development standards, as outlined in Renton Municipal Code (RMC) 4-2-110.A, if all conditions of approval are met: Compliance R-8 Zone Develop Standards and Analysis  Density: The allowed density range in the R-8 zone is a minimum of 4.0 to a maximum of 8.0 dwelling units per net acre. Net density is calculated after the deduction of sensitive areas, areas intended for public right-of-way, and private access easements. Staff Comment: The project site has a net site area of 21,591 square feet (0.49 acres) after the deduction of 1,038 square feet of fire turn-around tract from the 22,629 gross site area. The proposal for 3 lots on the 0.49 acre site results in a net density of 6.05 dwelling unit per net acre, which is within the density range permitted in the R-8 zone.  Lot Dimensions: The minimum lot size permitted in the R-8 zone is 5,000 sq. ft. A minimum lot width of 50 feet is required (60 feet for corner lots) and a minimum lot depth of 80 feet is required. The following table identifies the proposed approximate dimensions for Lots A - C Proposed Lot Lot Size (sq. ft.) Lot Width (ft.) Lot Depth (ft.) Lot A 11,589 100 115.75 Lot B 5,002 50 Approximately 107’ Lot C 5,000 50 Approximately 107’ Staff Comment: All proposed lots would comply with the minimum lot size, width and depth requirements for the R-8 zone. However, per RMC 4-2-110D.14, for plats that create lots of a size large enough to allow future division under current lot size minimums and allow the potential to exceed current density maximums, covenants shall be filed as part of the final plat requiring that future division of those lots in question must be consistent with the maximum density requirements as measured DocuSign Envelope ID: F72C5D06-49BE-4814-BB99-20733D01C274 City of Renton Department of Community & Economic Development Sather Short Plat Administrative Report & Decision LUA18-000559 Report of October 30, 2018 Page 6 of 21 D_Admin Decision_Sather Short Plat_181030 within the plat as a whole as of the time of future division, as well as the general lot size and dimension minimums then in effect. Therefore, staff recommends as a condition of approval that the applicant record a covenant as part of final short plat, consistent with RMC 4-2-110D.14, and a draft version of this covenant shall be submitted for review and approval by the current planning project manager prior to short plat recording.  Setbacks: The required setbacks in the R-8 zone are as follows: front yard is 20 feet, side yard is 5 feet, secondary front yard (applies to corner lots) is 15 feet, and the rear yard is 20 feet. Staff Comment: The lots as proposed provide adequate area for the construction of new homes in compliance with the setback requirements. An existing single-family residence is proposed to be retained on Lot A. The proposed rear yard setback between the existing home and the new property line is approximately 62 feet, which complies with minimum rear yard setback requirements. The orientation of Lot A has the front yard facing a public street, SW 3rd PL. The orientation of Lot B and C has the front yards facing the public alley, SW 3rd St. The applicant will need to demonstrate compliance with setback requirements for Lots B and C at the time of building permit review.  Building Standards: The R-8 zone has a maximum building coverage of 50% and a maximum impervious surface coverage of 65%. In the R-8 zone, a maximum building height of 2 stories with a wall plate height of 24 feet is permitted. Roofs with a pitch equal to or greater than 4:12 may project an additional six (6) vertical feet from the maximum wall plate height. If the height of wall plates on a building are less than the states maximum the roof may project higher to account for the difference, yet the combined height of both features shall not exceed the combined maximums. Common rooftop features, such as chimneys, may project an additional four (4) vertical feet from the roof surface. Non-exempt vertical projections (e.g., roofs pitched less than 4:12, decks, railings, etc.) may extend up to six (6) vertical feet above the maximum wall plate height if the projection is stepped back one-and-a-half (1.5) horizontal feet from each minimum building setback line for each one (1) vertical foot above the maximum wall plate height. Wall plates supporting a primary roof surface that has only one (1) sloping plane (e.g., shed roof) may exceed the stated maximum if the average of wall plate heights is equal or less than the maximum wall plate height allowed. Staff Comment: The existing single-family home on Lot A has a building footprint of approximately 1,305 square feet and a building coverage of 11.3 percent (1,305 sf / 11,589 sf = 11.3%). Lot A also contains approximately 678 square feet of rockery, walkway, and patio, for a total impervious area of 1,983 square feet. The impervious area for Lot A is approximately 17 percent (1,983 sf / 11,589 sf = 17%). No changes to the existing single-family home are currently proposed. The existing one-story, single- family structure complies with the building coverage and impervious surface requirements of the R-8 zone. Building height, building coverage, and impervious surface coverage for the new single-family residences proposed on lots B and C would be verified at the time of building permit review. Compliant if condition of approval is met Landscaping: The City’s landscape regulations (RMC 4-4-070) require a 10-foot landscape strip along all public street frontages. Additional minimum planting strip widths between the curb and sidewalk are established according to the street development standards of RMC 4-6-060. Street trees and, at a minimum, groundcover, are to be located in this area when present. Spacing standards shall be as stipulated by DocuSign Envelope ID: F72C5D06-49BE-4814-BB99-20733D01C274 City of Renton Department of Community & Economic Development Sather Short Plat Administrative Report & Decision LUA18-000559 Report of October 30, 2018 Page 7 of 21 D_Admin Decision_Sather Short Plat_181030 the Department of Community and Economic Development, provided there shall be a minimum of one street tree planted per address. Any additional undeveloped right-of- way areas shall be landscaped unless otherwise determined by the Administrator. Where there is insufficient right-of-way space or no public frontage, street trees are required in the front yard subject to approval of the Administrator. A minimum of two trees are to be located in the front yard prior to final inspection for the new Single- Family Residence. Staff Comment: A Conceptual Landscape Plan (Exhibit 3) was submitted with the preliminary short plat application materials. Public right-of-way (ROW) improvements are not proposed with this subdivision. Where there is insufficient ROW space or no public frontage, street trees are required in the front yard subject to approval of the Administrator. A minimum of two (2) trees are required to be located in the front yard prior to final inspection for the new Single-Family Residences. Based on the provided landscape plan, a minimum of two (2) front yard trees are proposed on each lot, which complies with this requirement. The conceptual landscape plan shows landscaping along the street frontage of the new Lots B and C (SW 3rd ST); however, the landscape plan does not show the required street frontage landscaping area along SW 3d Place. In addition, the provided conception landscape plan does not specify the quantity or size of proposed shrubs or groundcover within the street frontage landscaping. Therefore, staff recommends, as a condition of approval, that the applicant submit a final detailed landscape plan in compliance with RMC 4-8-120D.12 that includes required street frontage landscaping on both streets at the time of utility construction permit application for review and approval by the current planning project manager prior to construction permit issuance. In addition, street frontage landscaping along SW 3rd PL shall be installed prior to short plat recording. Compliant if conditions of approval are met Tree Retention: The City’s adopted Tree Retention and Land Clearing Regulations (4- 4-130) require the retention of 30 percent of trees in a residential development. Significant trees shall be retained in the following priority order: Priority One: Landmark trees; significant trees that form a continuous canopy; significant trees on slopes greater than twenty percent (20%); significant trees adjacent to critical areas and their associated buffers; and significant trees over sixty feet (60') in height or greater than eighteen inches ( 18") caliper. Priority Two: Healthy tree groupings whose associated undergrowth can be preserved; other significant native evergreen or deciduous trees; and other significant non- native trees. Priority Three: Alders and cottonwoods shall be retained when all other trees have been evaluated for retention and are not able to be retained, unless the alders and/ or cottonwoods are used as part of an approved enhancement project within a critical area or its buffer. A minimum tree density shall be maintained on each residentially zoned lot. For detached single-family development, the minimum tree density is two (2) significant trees for every five thousand (5,000) square feet. The tree density may consist of existing trees, replacement trees, trees required pursuant to RMC 4-4-070F1, Street Frontage Landscaping Required, or a combination. Staff Comment: A conceptual Tree Retention Plan (Exhibit 5), arborist report, and arborist report addendum (Exhibit 4) were submitted with the project application DocuSign Envelope ID: F72C5D06-49BE-4814-BB99-20733D01C274 City of Renton Department of Community & Economic Development Sather Short Plat Administrative Report & Decision LUA18-000559 Report of October 30, 2018 Page 8 of 21 D_Admin Decision_Sather Short Plat_181030 materials. The Tree Retention Plan and Arborist Report identify 29 significant trees onsite. Two (2) of the trees (Identified as tree number 6 and 11 in the arborist report) are identified in the arborist report as non-viable based on poor health/condition and are recommended for removal. One (1) tree is located in the proposed turnaround/access tract. A total of 26 trees remain following the deduction of non-viable trees and trees located within the turnaround/access easement. Thirteen (13) of the 26 trees are proposed for removal due to proximity to proposed new single-family residences. The proposed tree retention of nine (9) trees complies with the minimum tree retention requirements of the R-8 zone, providing 35 percent (35%) retention. Per RMC 4-4-130A, the purpose of the tree retention and land clearing regulations is to preserve and enhance the City’s physical and aesthetic character by minimizing indiscriminate removal or destruction of trees, as well as promoting land development practices that result in minimal adverse disturbance to existing vegetation. This goal is further promoted by RMC 4-4-130H.1.b, which prioritizes the retention of significant trees that form a continuous canopy. Trees number 14, a 26-inch caliper Fir tree (as shown in Exhibit 4), is located in the rear yard of Lot B. City Arborist, Terry Flatley, visited the site and observed that this tree is one of the largest and tallest trees on the site. In addition, this tree is in close proximity to a neighboring offsite tree, which is also a 26- inch caliper Fir tree. City staff observed that both trees together create a continuous and impressive canopy which adds value to the character of the community. In addition, city staff has received public comment requesting that tree number 14 be retained due to its close proximity to the other offsite Fir tree, as well as the added privacy that this tree provides. Therefore, in order to preserve the mature tree canopy and neighborhood privacy/character, staff recommends a condition of approval that tree number 14 be retained, and that the applicant submit a tree retention plan with the civil construction permit that shows the required tree retention fencing at a minimum of 20 feet around the tree. In addition, the tree retention plan shall be revised to include offsite trees within 10 feet of the property, and required tree protection fencing shall be identified on the plan for offsite trees. In addition to complying with the minimum tree retention requirements, the applicant is required to retain or plant two (2) significant trees, or gross equivalent caliper inches, per 5,000 square feet of lot area. A minimum of five (5) trees are required on Lot A to comply with tree density requirements. The conceptual Landscape Plan demonstrates compliance for Lot A by showing a total of nine (9) significant trees. In addition, the applicant proposes two 2-inch caliper trees on both Lots B and C, as shown on the landscape plan (Exhibit 3), which complies with minimum tree density requirements. Per RMC 4-4-130H.2, trees required to be retained (i.e., protected trees), that are not necessary to provide the required minimum tree density for residential lots, shall be preserved by establishing a tree protection tract that encompasses the drip line of all protected trees. Among the trees proposed to be retained, the applicant proposes to retain trees numbered 9, 8, 7, 10, 11, and 12, which are all located on the north portion of Lot A, in close proximity. Following deduction of these trees, Lot A will still comply with tree density requirement; therefore, staff recommends as a condition of approval, that the applicant submit a final detailed tree retention/landscape plan and short plat plan that shows and identifies trees numbered 9, 8, 7, 10, 11, and 12 within a tree protection tract. In addition, The permit holder shall establish and record a permanent and irrevocable deed restriction on the property title of the tree protection tract.

A draft version of a shared maintenance agreement shall be submitted for review and approval by the current planning project manager prior to short plat recording. Onsite landscaping shall be installed prior to final occupancy for the individual homes and landscaping within the ROW, if required, shall be installed prior to short plat recording.  Parking: Parking regulations require that a minimum of two parking spaces be provided for each detached dwelling. Driveway cuts are required to be a minimum of 5 feet from property lines and new driveways may be a maximum of 16 feet in width at the property line. Maximum driveway slopes shall not exceed fifteen percent (15%); provided, that driveways exceeding eight percent (8%) shall provide slotted drains at the lower end with positive drainage discharge to restrict runoff from entering the garage/residence or crossing any public sidewalk. Staff Comment: The existing single-family residence on proposed Lot A has adequate area to provide off-street parking for two vehicles. Compliance with the parking and driveway requirements for the new single-family residences would be verified at the time of building permit review. 15. Design Standards: Residential Design and Open Space Standards (RMC 4-2-115) are applicable in the R- 8 zone. The Standards implement policies established in the Land Use Element of the Comprehensive Plan. Compliance with Site Design Standards must be demonstrated prior to approval of the subdivision. Compliance with Residential Design Standards would be verified prior to issuance of the building permit for the new single-family homes. The proposal is consistent with the following design standards, unless noted otherwise: Compliance R-8 Design Standards and Analysis N/A Lot Configuration: One of the following is required of preliminary plat applications: 1.

Critical Areas: Project sites which contain critical areas are required to comply with the Critical Areas Regulations (RMC 4-3-050). The proposal is consistent with the Critical Areas Regulations, if all conditions of approval are complied with: Compliance Critical Areas Analysis Compliant if condition of approval is met Geologically Hazardous Areas: Based upon the results of a geotechnical report and/or independent review, conditions of approval for developments may include buffers and/or setbacks from buffers. A standard 15-foot building setback is required for all structures from Protected Slope areas. A 50-foot buffer and 15-foot building setback are required from Very High Landslide Hazard Areas. Staff Comment: City Records indicate that high landslide hazards and sensitive slope are mapped on the subject site. A geotechnical engineering report, dated April 7, 2017, completed by Riley Group, Inc. (RCI), was provided with the application (Exhibit 8). RGI’s geotechnical scope of work included the advancement of four test pits to a maximum depth of 6 feet below ground surface (bgs). According to the report, the site is underlain by 5 feet of fill or surficial soils comprised of loose to medium dense silty sand with trace organics over very dense sandstone bedrock. As part of the evaluation, light groundwater was encountered at 3 and 5 feet bgs in one of the test pits during the subsurface exploration. The report states that the site slopes generally to the south with an overall elevation difference of about 50 feet. On March 22, 2017, RGI’s geologist performed a site reconnaissance to evaluate the stability of the site slope. During the field observations, RGI did not find any signs such as rotational failures, tension cracks or exposed slope surfaces indicating previous major landslide activities. No seeps or springs were observed on the slope face through most of the property. The report states that the slope onsite is vegetated with blackberry brambles, vines, ferns, and mixed brush, with localized small- to medium- diameter deciduous trees scattered throughout the slope. Based their observations, the slopes appear to be stable in their current configuration and condition. The report concludes that the site is suitable for the proposed construction from a geotechnical standpoint. RGI recommends that proposed buildings be supported on spread footings bearing on medium dense native soil, bedrock or new structural fill, and that slab-on-grade can be similarly supported on medium dense native soil or structural fill. The report further states that impacts on erosion-prone areas can be reduced by implementing an erosion and sedimentation control plan. The geotechnical study will need to be submitted with construction and building permit application. The study provides recommendations including, but not limited to, erosion control, stripping, site preparation, structural fill, foundations, and drainage. Staff recommends as a condition of approval, that project construction comply with the recommendations found in the geotechnical engineering report completed by Riley Group, Inc. (dated April 7, 2017) for the subdivision.

Compliance with Subdivision Regulations: RMC 4-7 Provides review criteria for the subdivisions. The proposal is consistent with the following subdivision regulations if all conditions of approval are complied with: Compliance Subdivision Regulations and Analysis Compliant if conditions of approval are met Access: Each lot must have access to a public street or road. Access may be by a shared driveway per the requirements of RMC 4-6-060 Street Standards. The maximum width of single loaded garage driveways shall not exceed nine feet (9') and double loaded garage driveways shall not exceed sixteen feet (16'). Staff Comment: The applicant is proposing to retain access to the existing home on proposed Lot A via an existing residential driveway off of SW 3rd Place to the south. Access to Lots B and C would be provided via an existing alley (SW 3rd Street) along the north property line and a 1,039 square foot emergency turnaround tract which extends off of the alley. Alley access is the preferred street pattern for all new residential development except in the Residential Low Density land use designation (RC, R-1, and R-4 zones). Both Lots B and C would access off of an existing residential alley, and therefore comply with this requirement. The short plat proposal does not include alley access for Lot A, which currently accesses from SW 3rd Place. The City uses the following factors to determine whether the use of alleys is not practical, including: a) Size: The new development is a short plat; b) Topography: The topography of the site proposed for development is not conducive for an alley configuration; c) Environmental Impacts: The use of alleys would have more of a negative impact on the environment than a street pattern without alleys; d) If site characteristics allow for the effective use of alleys (RMC 4-7-150E.5). Proposed Lot A has public street frontage on SW 3rd Place, and would not have alley access with the proposed short plat. The existing site characteristics, topography, and dimensions do not allow for a practical use of alley access for Lot A. Driveways shall be designed in accordance with RMC 4-4-080, Parking, Loading, and Driveway Regulations. Per subsection I.6 of this section, driveways shall not exceed a slope of 15% without an approved variance. Based on the existing topography of the site (Exhibit 2), the existing slopes are approximately 21 percent in the vicinity of the proposed emergency turn around. In order to ensure access feasibility, staff recommends as a condition of approval that the applicant submit a conceptual site grading plan that demonstrates compliance with driveway and tree protection regulations with the civil construction submittal, for review and approval by the current planning project manager, and site grading in accordance with the approved plan shall be completed with the civil construction permit, prior to short plat recording. In addition, in order to ensure that additional curb cuts are not needed, staff recommends as a condition of approval that both Lots B and C access off of the emergency turnaround tract via residential driveways. No parking shall be permitted within the emergency turnaround tract. A public access easement shall be placed over the proposed turnaround tract. The applicant would be required to record a note on the face of the plat that executes a shared maintenance agreement between Lots B and C (Excluding Lot A) for equal ownership and maintenance responsibilities for improvements in the new emergency turnaround tract. A draft version of a shared maintenance agreement shall be submitted for review and approval by the current planning project manager prior to short plat recording.

Staff Comment: Not applicable, no blocks are proposed. Projects are exempt from block depth regulation when the location and extent of environmental constraints prevent a standard plat land configuration.  Lots: The size, shape, orientation, and arrangement of the proposed lots comply with the requirements of the Subdivision Regulations and the Development Standards of the R-8 zone and allow for reasonable infill of developable land. All of the proposed lots shall meet the requirements for minimum lot size, depth, and width. Width between side lot lines at their foremost points (i.e., the points where the side lot lines intersect with the street right-of-way line) shall not be less than eighty percent (80%) of the required lot width except in the cases of (1) pipestem lots (or flag lot), which shall have a minimum width of twenty feet (20') and (2) lots on a street curve or the turning circle of cul-de-sac (radial lots), which shall be a minimum of thirty five feet (35'). No residentially zoned lot shall have a depth-to-width ratio greater than four-to-one (4:1). Pipestem lots may be permitted for new plats to achieve the minimum density within the Zoning Code when there is no other feasible alternative to achieving the minimum density. Staff Comment: As discussed above under FOF 14, all lots meet the minimum lot size and dimensional requirements in the R-8 zone. Proposed Lot A is rectangular in shape. Due to the deduction of Tract A, which is a fire hammerhead turnaround, Lots B and C have irregular shaped lots with one curved lot corner. The orientation of Lot A has the front yard facing a public street, SW 3rd PL. The orientation of Lot B and C has the front yards facing the public alley, SW 3rd St. The building design of the new residences on Lots B and C would be reviewed and approved at the time of building permit application. Compliant if condition of approval is met Streets: The proposed street system shall extend and create connections between existing streets per the Street Standards outlined in RMC 4-6-060 Street Standards. Staff Comment: The proposed access to Lot A is provided via an existing residential driveway off of SW 3rd Place to the south. Access to Lots B and C is proposed via an existing alley (SW 3rd Street) along the north property line and a 1,039 square foot emergency turnaround tract which extends off of the alley. SW 3rd Place is classified as a residential access street. Existing right-of-way (ROW) width, according to the King County Assessor Map, is 60 feet for SW 3rd Place and 20 feet for the alley. Per RMC 4-6- 060, the minimum ROW width for residential access street is 53 feet; therefore, no (ROW) dedication is required for SW 3rd Place. To meet the City’s complete street standards for residential access streets, 13 feet of pavement from center line, a 0.5-foot curb and gutter, 8-foot planter, and 5-foot sidewalk are required. The applicant has submitted a request for Fee in Lieu of Street Improvements. Due to the existing street pattern within the neighborhood, staff recommend approval of the requested street frontage Fee in Lieu. The application must be signed and dated, and the required fees will be subject to payment at the time of civil construction permit application.

Availability and Impact on Public Services: Compliance Availability and Impact on Public Services Analysis  Police and Fire: Police and Fire Prevention staff indicates that sufficient resources exist to furnish services to the proposed development; subject to the condition that the applicant provides Code required improvements and fees. The current rate of fire impact fee is $829.77 per new single-family house. Fees are subject to change. The fire impact fee that is current at the time of building permit application would be levied. Compliant if condition of approval is met Schools: It is anticipated that the Renton School District can accommodate any additional students generated by this proposal at the following schools: Bryn Mawr Elementary, Dimmitt Middle School and Renton High School. Any new students from the proposed development would be bussed to their schools. The bus stop for Bryn Mawr Elementary and Dimmitt Middle School is located approximately 0.20 miles from the project site at the corner Stevens Ave SW and SW Langston Rd. Students from Lots B and C would exit the residential alley (SW 3rd ST) and walk along the east shoulder of Earlington Ave SW to SW Langston Rd, where they would turn right and continue on a sidewalk to the corner of SW Langton Rd and Stevens Ave SW. Students from Lot A would walk on the north shoulder of SW 3rd PL and take a left and continue on the left shoulder of Stevens Ave SW to the same corner bus stop. This The existing alley ROW width is 20 feet. Frontage Improvements along the alley are not required since the existing ROW meets the minimum standards for alleys, per RMC 4-4- 060. As stated above, the applicant is also proposing a 1,039 SF emergency turnaround tract which extends off of the alley for emergency services access. The existing paved alley width is 14 feet and does not comply with the requirements for emergency services. Fire department apparatus access roadways are required to be a minimum of 20 feet wide fully paved, with 25 feet inside and 45 feet outside turning radius. Therefore, staff recommends, as a condition of approval, that the applicant either request a variance from the fire code to allow a 14-foot wide fully paved fire apparatus access roadway, or provide a 20-foot wide paved alley for emergency vehicles in order to provide fire access to within 150 feet of all points on each building. Payment of the transportation impact fee is applicable on the construction of the single- family houses at the time of application for the building permit. The current rate of transportation impact fee is $5,430.85 per new single-family house. Fees are subject to change. The transportation impact fee that is current at the time of building permit application would be levied.  Relationship to Existing Uses: The proposed project is compatible with existing surrounding uses. Staff Comment: The proposed short plat is surrounded by existing detached single- family residences to the north, south, east, and west of the site. All surrounding properties are also located in the R-8 zone. The proposed lots are similar in size and shape to the existing surrounding development pattern in the area and would be consistent with the Comprehensive Plan and Zoning Code, which encourages residential infill development in the Residential Medium Density (MD) Comprehensive Plan land use designation and R-8 zoning designations. Therefore, the proposal for new single- family homes would be compatible with the existing uses in the area.

Due to the uneven shoulders and incomplete sidewalks, improvements to Earlington Ave SW and Stevens Ave SW may be required in order to establish a safe walking route to the bus stop located on the corner of Stevens Ave SW and SW Langston Rd. Improvements may include lane paint stripes or barriers. Therefore, staff recommends, as a condition of approval, that the applicant provide a safe route to school plan, which includes lane paint and/or barriers, for review and approval by the Current Planning Project Manager, prior to construction permit issuance. Lastly, the bus stop for Renton High School is located approximately 0.16 miles from the project site at Thomas Ave SW and SW 3rd PL. Students from Lots B and C would exit the residential alley (SW 3rd ST) and walk along the east shoulder of Earlington Ave SW to SW 3rd PL, where they would cross the street to the west and continue on the north shoulder of SW 3rd PL till they reach the corner of Thomas Ave SW and SW 3rd PL. Students from Lot A would walk on the north shoulder of SW 3d PL towards the west until they reach the same corner stop. These routes are not improved with sidewalks; however, the existing shoulders would provide a safe walking route for students to walk to the bus stop. A School Impact Fee, based on new single-family lots, will be required in order to mitigate the proposal’s potential impacts to the Renton School District. The current rate of school impact fee is $7,772 per new single-family house. Fees are subject to change. The school impact fee that is current at the time of building permit application would be levied.  Parks: A Park Impact Fee would be required for the future houses. The current rate of park impact fee is $2,740.07 per new single-family house. Fees are subject to change. The park impact fee that is current at the time of building permit application would be levied. Compliant if condition of approval is met Storm Water: An adequate drainage system shall be provided for the proper drainage of all surface water. Staff Comment: A geotechnical report, dated April 7, 2017, completed by The Riley Group, Inc. for the site has been provided. The report discusses the soil and groundwater characteristics of the site including infiltration potential and provides recommendations for project design and construction. The report states that infiltration is not suitable due to the native soil or bedrock. A Preliminary Utility Plan and Technical Information Report (TIR) prepared by Triad (Exhibit 6), dated July 31, 2018, was submitted with the Land Use Application. Based on the City of Renton’s flow control map, the site falls within the City’s Peak Rate Flow Control Standard (Existing Site Conditions) and is within the Black River Drainage Basin. The development is subject to Directed Drainage Review in accordance with the Renton Surface Water Design Manual (RSWDM). All nine core requirements and the six special requirements must be discussed in the TIR and appropriate onsite BMPs will be required to help mitigate the new runoff created by this development. The provided TIR does not include the entire property and alley as part of the project area. In addition, a preliminary drainage plan, including the application of onsite BMPs, has not been included with the land use application. A final drainage plan and revised drainage report will be required with the civil construction permit application, prior to civil construction permit issuance. Within the revised TIR, all requirements must be revised to include the entire property and any disturbed area (alley) as the project area.

Patty: This report is provided to address the recent inventory I conducted on the property at the address of 532 SW 3rd Pl. in the City of Renton. Please see the accompanying Tree Inventory Map and Tree Evaluation Data spreadsheet for reference to this report. 1. Site Conditions and Proposed Development The property is located in Renton in an area primarily developed with single family residences. The project site is currently developed as a nursery with several buildings, greenhouses and a home. The site slopes downward to the south. The proposed development of the site is to short plat it into as many as four single family residence lots. 2. Tree Inventory Methods and Results I visited the site on May 22, 2017 to conduct an inventory and gather information on all of the trees during which I labeled them with numbered metal tags which correspond to the numbers on the inventory map and in the tree evaluation data spreadsheet. I conducted visual condition assessments according to the methods and procedures specified in the ISA Tree Risk Assessment Manual (2013) by viewing them up close to observe the trunk and root collar and from afar to observe conditions in the crown. The tree evaluation data spreadsheet provides information on all of the trees. In total, I conducted evaluations on 29 trees. One tree shown on the survey has recently fallen. The accompanying Tree Evaluation Data spreadsheet provides information on all of the inventoried trees. Two of the trees on the site, both western red cedars (#6 and #11) have very sparse crowns, a condition that is indicative of decline that will ultimately end in 1 EXHIBIT 4 DocuSign Envelope ID: F72C5D06-49BE-4814-BB99-20733D01C274 the death of these trees very soon. In my opinion, these trees should not be retained as they will soon need to be removed. 3. Tree Retention and Replacement Required and Proposed This property is located in a residential zone and is planned to be developed with single family residences, therefore the City of Renton specifies tree retention at 2 trees per every 5,000 square feet of property area. The project site measures 22,920 square feet requiring the retention/replacement with 9 trees. Trees 30” and greater are classified as landmark in the City of Renton and are prohibited from removal without an approved Vegetation Management Plan or a Land Development Permit. There are 2 trees on the site that meet the size threshold to be classifed as landmark. They are trees #6 and #9. Number 6, however, is in an advanced state of decline and not recommended to be retained as it will need to be removed in the near future once it has died. A total of 12 trees, including the healthy exceptional tree (#9) are proposed to be retained satisfying the requirement for tree retention on developing lots in the City of Renton. For trees not retained to meet the minimum requirement, replacement trees are to be 2 inch caliper for deciduous trees and a minimum of 6’ in height for evergreen trees. For trees not planted as replacement below the required minimum, section 3.H. 1.e.iii of the RMC specifies the following: iii. Fee in Lieu: When the Administrator determines that it is infeasible to replace trees on the site, payment into the City’s Urban Forestry Program fund may be approved in an amount of money approximating the current market value of the replacement trees and the labor to install them. The City shall determine the value of replacement trees. No tree replacement is required on this project as the required tree retention is being provided. 4. Impact Assessment This impact assessment is to provide information on the potential impact removing trees will have on the retained trees. Most of the trees to be removed are on the new lots, to the north of the existing residence. Three trees to be removed on the existing lot are east of the trees to be retained on that lot. The main impact associated with the removal of trees on retained trees is the increase in exposure of the retained trees to winds. In this area, the prevailing winds (which create the strongest gusts) blow from the south to southwest. Since 2 DocuSign Envelope ID: F72C5D06-49BE-4814-BB99-20733D01C274 all of the trees to be removed are north or east of the trees to be retained, the removal of trees on the site will not increase the exposure of the retained trees, therefore, they will not be impacted. 5. Tree Protection Measures The following tree protection measures are required for all of the retained trees: • Prior to beginning any work on the site, including clearing and grading, protection fencing is to be installed at the required locations at or beyond the dripline edge. • The fencing is to be a type required or approved by the City of Renton. • Signs calling out the area within the fencing as the Tree Protection Zone - No Entry, No Dumping, No Storage of Materials and No Machinery, are to be hung from the fencing around each tree. • The fencing is to remain in place throughout construction and removed only upon approval of the City of Renton. Any impacts proposed within the tree protection zone is to be evaluated and assessed for extent of impacts by the project consulting arborist. 5. Use of This Report and Limitations This report is provided to Patty Sather as a means of reporting on the conditions and statuses of the trees located on the short plat project site in the City of Renton. While Shoffner Consulting has used every means available to determine tree health and development impacts, trees are dynamic and their conditions can change rapidly given changes in environmental factors and site development, therefore this assessment pertains only for those noted on the day of their evaluation, and no guarantee can be made against damage caused by unforeseen development-related impacts. Natural decline and failure of trees is not predictable. Cordially, !

Renton, WA 98057 RE: Tree Inventory and Retention Plan Addendum - Sather SP, Renton, WA. Patty: This report is provided as an addendum to the original report dated May 30, 2017 reporting on the tree inventory of your property at the address of 532 SW 3rd Pl. in the City of Renton WA. This addendum addresses recent site plan changes that require the removal of additional trees. 1.0 Site Plan Tree Retention Revisions In order to achieve the 5,000 s.f. minimum lot size, both lots will be shifted just over 10 feet to the south into lot A. This adjustment moves development related impacts into the protection zones of trees 13, 14 and 23. These impacts call for grading and excavation that will result in significant damage to the root systems of these trees, encroaching into their root plates, the region wherein the major structural roots provide the most stabilization function. This significant encroachment and resulting root loss will also remove more than the recommended 1/3 total root area which will have a significant impact upon the growth of the trees. The reduced ability of these trees to maintain the current levels of water, oxygen and nutrient uptake will impair their growth and repair functions. Given these impacts, these trees will no longer be good candidates for retention and therefore are recommended to be removed. 2.0 Required Tree Retention and Proposed The property is located in a residential zone and is planned to be single family residences, therefore tree retention is required at 2 trees per every 5,000 square feet of property area. At total area of 22,920 square feet, retention/replacent is required with 9 trees. The prior site plan proposed the retention of the following 12 trees: 2, 3, 4, 7, 8, 9, 10, 11, 12, 13, 14 and 23. The removal of trees 13, 14 and 23 due to the discussed site plan changes will still maintain the required 9 trees to be retained, satisfying the City of Renton’s tree retention requirements. 4.0 Use of This Report This addendum to the original Tree Inventory and Retention Plan report is provided to Patty Sather as a means of addressing the proposed site plan changes and the resulting impacts to trees previously proposed to be retained affecting the total tree retention numbers. No site visit was made for the preparation of this report, therefore, DocuSign Envelope ID: F72C5D06-49BE-4814-BB99-20733D01C274 the conditions of the trees proposed to be retained are not specified nor warranted. Shoffner Consulting cannot be held liable for the failure of any retained trees. Please call if you have any additional questions.

The existing site contains one single family residence, three sheds, paved walkways, and associated driveways. The remainder of the site is forested and slopes heavily from north to south. WATER Water service is provided by the City of Renton. It is in the Earlington service area in the 370- feet hydraulic pressure zone. The approximate static water pressure is 80 pounds per square inch (psi) at a ground elevation of 182 feet. There is an existing 8-inch water main south of the site in SW 3rd Place that can deliver approximately 1,500 gallons per minute (gpm). Reference Project File WTR2703082 in COR Maps for record drawings. SEWER Sewer service is provided by the City of Renton. There is an existing 8-inch PVC sewer running northwest to southeast south of the site. Reference Project File WWP2703082 in COR Maps for record drawings. There is an existing sewer service for the existing home. Since this home will remain, no new sewer service is needed for this lot. A new 6-inch PVC sewer service will be needed to serve each new lot. The sewer service lines shall be contained in a utility easement where they pass through a shared driveway tract or neighboring parcel. STORM There is no existing on-site storm drainage system. The majority of the site contains slopes exceeding 15%. Drainage from the site sheet flows to the southwest. Drainage along the SW 3rd Place frontage is intercepted by a 12-inch concrete storm drain. Drainage enters the system in the vicinity of the site through two type 1 catch basins. One catch basin is located approximately 30 feet southeast of the site’s southeast corner (COR Facility ID 132476).

SW 3rd Place is classified as a residential access street. Existing right-of-way (ROW) width, according to the King County Assessor Map, is 60 feet for SW 3rd Place and 20 feet for the alley. CODE REQUIREMENTS WATER 1. There is an existing ¾-inch water service serving the existing home. This service is proposed to remain with the existing home. The Applicant is proposing two, 1-inch meters for B and C. The services will be installed in a Private Utility Easement along the east property line. 2. Meter sizing shall be based on Uniform Plumbing Code meter sizing criteria. Sizing calculations shall be provided to the City. 3. Installation of a pressure reducing valve (PRV) is required downstream of each meter if the pressure is over 80 psi. 4. Fire hydrant requirements per the fire department shall be met. 5. The fire flow requirement for a single-family home is 1,000 gpm minimum for dwellings up to 3,600 square feet (including garage and basements). If the dwelling exceeds 3,600 feet, a minimum of 1,500 gpm fire flow would be required. A minimum of one fire hydrant is required within 300 feet of the proposed buildings and two hydrants if the fire flow goes up to 1,500 gpm. Existing hydrants appear adequate to meet minimum requirements. a. There are three existing fire hydrants in the parcel vicinity. One is located across the street from 532 SW 3rd Place, 50 feet southeast of the SE corner of the lot. One is located at the NE corner of the SW 3rd Place and Earlington Avenue SW intersection approximately 125 feet northwest of the southwest property corner. Another is located along the eastern frontage of Earlington Avenue SW approximately 40 feet northeast of the alley and Earlington Avenue SW intersection. 6.The service line and meter for the new lots would be installed by the City of Renton. The current (2018) fee to install one (1) service and meter would be $3,310.00. The development is subject to system development charges (SDCs) for water service.
