The project site is located at 3605 NE 7th Street. 3. The project site is currently developed with a single-family home and associated detached garage, which would be demolished as part of the project. 4. Access to the site would be provided via a new shared driveway off of NE 7th Street. 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 is one (1) existing tree onsite which is proposed for removal. 8. A sensitive slope is mapped within 50 feet of the project site. 9. The applicant anticipates that the project will require approximatley 100 cubic feet of cut and 1,700 cubic feet of fill. 10. The applicant is proposing to begin construction immediately following landuse and building permit approval. 11. Staff received no public or agency comment letters. 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 Residential 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  Policy L-3: Encourage infill development of single-family units as a means to meet growth targets and provide new housing.  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  Infill development on vacant and underutilized land in established neighborhoods and multi-family areas.  Policy L-28: Minimize erosion and sedimentation in and near sensitive areas by requiring appropriate construction techniques and resource practices, such as low impact development.

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 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 21,359 square feet (0.49 acres) after the deduction of a 6,346 square foot of shared driveway from the 27,705 gross site area. The proposal for 3 lots on the 0.49 acre site results in a net density of 6.1 dwelling unit per net acre, which is within the density range permitted in the R-8 zone. Compliance not yet demonstrated Lot Dimensions: The minimum lot size permitted in the R-8 zone is 5,000 sq. ft. The R- 8 zone requires a minimum lot width of 50 feet (60 feet for corner lots) and a minimum lot depth of 80 feet. However, the underlying plat states that lots shall not be subdivided with less than 6,000 square feet per lot with a minimum lot width of 60 feet (See Exhibit 9). The following table identifies the proposed approximate dimensions for Lots 1, 2, and 3. Proposed Lot Lot Size (sq. ft.) Lot Width (ft.) Lot Depth (ft.) Lot 1 (corner lot) 6,032 67.95 85.92 Lot 2 (corner lot) 6,047 67.96 85.92 Lot 3 9,280 95.97 96.76 Tract “A” 6,346 28.01 192.05 DocuSign Envelope ID: 35719AF6-30FE-463D-BA01-F406CF7F122E City of Renton Department of Community & Economic Development 7th Street Short Plat Administrative Report & Decision LUA19-000185, SHPL-A Report of December 3, 2019 Page 6 of 18 D_Admin Decision_7th Street Short Plat Stormwater Detention Vault Tract Approximately 1,238 Approximately 20 Approximately 61.8 Staff Comment: All lots, as currently proposed, comply with the minimum lot dimension standards of the R-8 zone and the underlying plat. However, the proposed stormwater detention vault is required to be located within a dedicated tract (See addition discussion under FOF 17, Compliance with Subdivision Regulations: Utilities in Tracts), which may impact Lot 3. The applicant will need to demonstrate compliance with minimum lot size (6,000 square feet) and lot width (60 feet) requirements for the underlying plat, after deduction of the required storm drainage facility tract, at the time of Civil Construction Permit application. Compliant if condition of approval is met 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 and detached accessory structure are proposed for removal. The existing single-family residence and accessory structure do not comply with minimum setback requirements after the creation of the new lot lines. Therefore, staff recommends, as a condition of approval, that demolition permits be obtained for the existing residence and accessory structure, and all required inspections completed, prior to the approval of the final short plat. Per RMC 4-6-060J.7., the administrator may permit lots that only front a shared driveway to be designated as a corner lot. While proposed Lot 2 does not comply with minimum lot depth requirements for an interior lot facing the shared driveway, proposed Lot 2 does comply with corner lot dimension requirements, consistent with RMC 4-6-060J.7. However, the site plan submitted with the project application (See Exhibit 2) does not comply with corner lot setback requirements. In the case of residential corner lots, there is no required rear yard setback. Setbacks for corner lots are allowed two (2) front yard setbacks adjacent to the public and private streets and two (2) or more side yards setbacks on common residential property lines. Where the side yard along a street setback is less than the required front yard setback, the smaller setback shall apply on the street when the façade is not associated with the front entry of the home. In the case of Lot 1, the front yard setback shall front the north property line and the secondary front yard setback shall front the east property line. In the case of Lot 2, the front yard setback shall front the east property line and the secondary front yard setback shall front the north property line. The lots, as proposed, provide adequate room to comply with corner lot setback requirements for Lots 1 and 2. Compliance not yet demonstrated 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, DocuSign Envelope ID: 35719AF6-30FE-463D-BA01-F406CF7F122E City of Renton Department of Community & Economic Development 7th Street Short Plat Administrative Report & Decision LUA19-000185, SHPL-A Report of December 3, 2019 Page 7 of 18 D_Admin Decision_7th Street Short Plat 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: Building height, building coverage, and impervious surface coverage for the new single-family residences 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 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. The conceptual landscape plan shows an 8-foot wide landscape strip between the curb and sidewalk and an 8-foot wide landscape strip within the shared driveway tract. The proposed shared driveway landscaping includes a mixture of trees, shrubs, and groundcover, as required by code. The proposed 8-foot planter within the public right-of-way (ROW) includes trees and shrubs; however, the public ROW planter does not include groundcover as required by code, nor does it meet minimum requirements, which require a minimum of one street tree per address. In addition, the project is required to show a minimum 10-foot wide onsite landscape strip along the public street frontage. The proposal includes new trees along the street frontage; however, the proposed landscaping along the street frontage does not demonstrate compliance with dimensional requirements for street frontage landscaping, nor does the proposed street frontage landscaping include a mixture of trees, shrubs, and ground cover as required per RMC 4-4-070.H.1. 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 demonstrates compliance with street frontage landscaping and public right-of-way landscaping requirements per RMC 4-4-070F.2 and RMC 4-4-070H.1, at the time of Civil Construction Permit application for review and approval by the Current Planning Project Manager, prior to Construction Permit issuance. In addition, in order for this landscape area within the proposed shared driveway tract (Tract A) to be maintained equally by all lots, the applicant would be required to record a note on the face of the plat that executes a shared maintenance agreement for equal ownership and maintenance responsibilities for improvements in Tract A. Therefore, staff recommends as a condition of approval that the applicant submit a draft version DocuSign Envelope ID: 35719AF6-30FE-463D-BA01-F406CF7F122E City of Renton Department of Community & Economic Development 7th Street Short Plat Administrative Report & Decision LUA19-000185, SHPL-A Report of December 3, 2019 Page 8 of 18 D_Admin Decision_7th Street Short Plat of a shared maintenance agreement for review and approval by the Current Planning Project Manager, prior to short plat recording. Per RMC 4-4-070H.6.c., perimeter landscaping with a minimum depth of 15 feet is required around storm drainage facilities, within the boundaries of the required storm drainage facility tract, unless otherwise determined through the subdivision review process. The applicant is proposing a below-ground stormwater detention vault within a storm drainage easement on Lot 3; however, the stormwater detention vault is required to be located within a dedicated tract (See addition discussion under FOF 17, Compliance with Subdivision Regulations: Utilities in Tracts). The project proposal does not include the required 15 feet of perimeter landscaping. Provided the vault is located entirely underground, staff is supportive of removal of the required landscaping within the storm drainage facility tract. Therefore, staff recommends a condition of approval that the applicant either revise the project proposal to include the required 15 feet of perimeter landscaping around the proposed stormwater detention vault, or the applicant shall submit stormwater detention vault profiles that demonstrate that the vault will be located entirely underground. If the applicant creates a home owners association for ownership and maintenance responsibilities for improvements in Tract A, then HOA documents shall be submitted for review and approval by the current planning project manager and the City Attorney prior to short plat recording. On-site landscaping shall be installed prior to final occupancy for the individual homes and landscaping within the right-of-way and within Tract A shall be installed prior to short plat recording.  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: One (1) onsite significant tree was identified on the Tree Retention Plan (Exhibit 4) and Arborist Report (Exhibit 5) submitted with the project application. The existing onsite tree is located within the proposed share driveway tract. Trees within DocuSign Envelope ID: 35719AF6-30FE-463D-BA01-F406CF7F122E City of Renton Department of Community & Economic Development 7th Street Short Plat Administrative Report & Decision LUA19-000185, SHPL-A Report of December 3, 2019 Page 9 of 18 D_Admin Decision_7th Street Short Plat 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 shared driveways are excluded from tree retention standards; therefore, no trees are required to be retained on the site. In addition to complying with the minimum tree retention requirements, the applicant is required to retain or plant two (2) significant trees per 5,000 square feet of lot area. A minimum of two (2) trees are required on Lot 1 and Lot 2 to comply with tree density requirements. Based on proposed lot size, a minimum of four (4) trees are required on Lot 3 to comply with tree density requirements. The conceptual Landscape Plan (Exhibit 3) shows a total of six (6) proposed trees on Lot 1, including Flowering dogwood, Serbian Spruce, Forever goldie cedar, and Excelsa Cedar trees. A total of six (6) trees are proposed on Lot 2, including Flowering dogwood, Serbian Spruce, Forever golden cedar, Japanese Snowdrop, and Sargent’s weeping hemlock trees. A total of thirteen (13) trees are proposed on Lot 3, including Excelsa cedar, Serbian spruce, Sumi nagashi red maple, Sargent’s weeping hemlock, Forever Goldie cedar, and Paperbark maple trees. The project proposal demonstrates compliance with minimum tree density requirements for each lot.  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: Each lot contains adequate area for the provision of two parking spaces per dwelling unit, as required by RMC 4-4-080 required parking spaces. Parking requirements and driveway grades for each of the new residences proposed would be verified at the time of building permit review. Compliant if condition of approval is met Fences and Retaining Walls: In any residential district, the maximum height of any fence, hedge or retaining wall shall be seventy two inches (72"). Except in the front yard and side yard along a street setback where the fence shall not exceed forty eight inches (48") in height. There shall be a minimum three-foot (3') landscaped setback at the base of retaining walls abutting public rights-of-way. Staff Comment: The applicant proposes a new retaining wall along the west and south boundaries of the proposed subdivision. The proposed retaining wall has a minimum height of approximately 2 feet and a maximum height of approximately 8.5 feet. The proposed height within the front yard setback of Lot 1 reaches a maximum height of 4 feet, which is compliant with the maximum retaining wall height requirements for front yard setbacks; however, the proposed retaining wall exceeds the maximum overall height of 6 feet outside of the front yard setback. Therefore, staff recommends that the applicant either demonstrate compliance with the maximum retaining wall height requirements for the R-8 zone or submit a request for retaining wall modification, for review and approval, prior to civil construction permit issuance.

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  Sensitive Slopes: Staff Comment: City Records indicate that a sensitive slope is mapped within 50 feet of the subject site. A geotechnical report (Exhibit 7), dated September 28, 2018, prepared by Earth Solutions NW, was submitted with the short plat application materials. Earth Solutions NW’s geotechnical scope of work included the advancement of five test pits to a maximum depth of 8.5 feet below ground surface (bgs). According to the report, the site is underlain primarily by silty sand with gravel, consistent with the typical makeup of glacial till. At the time of the subsurface exploration completed on August 20, 2018, groundwater was not encountered at the test pit locations. The report states that the contractor should be prepared for discrete zones of groundwater seepage during construction depending on the time of year construction occurs. The report states that topography maintains a south/southwesterly declination, with a 10- foot elevation change occurring within the property boundaries. Earth Solutions NW observed slopes from east to west on site at an approximate gradient ranging from 5% to 10%, with isolated areas up to 30%. The report provides recommendations for permanent and temporary slope inclinations during excavation activities. The report concludes that the proposed residential short plat is feasible from a geotechnical standpoint. Earth Solutions NW states that the proposed buildings be supported on conventional continuous and spread footing foundations bearing upon competent native soil, recompacted native soil, or new structural fill placed directly on competent native soils. 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 Earth Solutions NW, Inc. (dated September 28, 2018) for the subdivision. 17. 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 condition of approval is 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. In the R-6 and R-6, new lots shall utilize an alley or vehicular access and shall orient new homes towards to the rear of the property. 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: Along the west property line, the applicant is proposing a 28 foot wide by 192.05 foot long (6,346 SF) shared driveway tract, with a 20-foot wide paved shared DocuSign Envelope ID: 35719AF6-30FE-463D-BA01-F406CF7F122E City of Renton Department of Community & Economic Development 7th Street Short Plat Administrative Report & Decision LUA19-000185, SHPL-A Report of December 3, 2019 Page 13 of 18 D_Admin Decision_7th Street Short Plat driveway and turnaround, to serve the three lots. Access to each of the lots would be gained via the proposed shared driveway (Tract A). Staff recommends as a condition of approval that all lots shall gain vehicle access from the new shared driveway, Tract A. This condition shall be recorded on the face of the Final Short Plat. In addition, no parking shall be permitted within the turnaround access easement. 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). 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). The short plat has public street frontage on NE 7th Street, and the use of alleys would not be characteristic of the neighborhood or practical. The existing street grid would not support alley access beyond the proposed construction of the access drive (Exhibit 2). In addition, in order to ensure that additional curb cuts are not needed, staff recommends as a condition of approval that both Lots 1 and 2 access off of the emergency turnaround tract via residential driveways. No parking shall be permitted within Tract A. The applicant shall install one “No Parking” on each side of the pavement within the turnaround, prior to short plat recording. As stated in FOF 14, Zoning Development Standard Compliance: Landscaping, the applicant would be required to record a note on the face of the plat that executes a shared maintenance agreement for equal ownership and maintenance responsibilities for improvements in Tract A. The maintenance agreement shall address both the roadway and the landscaping in the 8-foot landscape strip. 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. Compliant if condition of approval is met Utilities in Tracts: Utilities, such as stormwater vaults, ponds, or other structures, shall be located within dedicated tracts. Staff Comment: The project proposal includes a new proposed stormwater detention vault; however, the proposed vault is not located within a dedicated tract as required by code. Therefore, the staff recommends as a condition of approval that the applicant revise the proposal to include the proposed stormwater detention vault within a dedicated tract. Compliance with this requirement shall be demonstrated at the time of Civil Construction Permit application. N/A Blocks: Blocks shall be deep enough to allow two (2) tiers of lots. 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. DocuSign Envelope ID: 35719AF6-30FE-463D-BA01-F406CF7F122E City of Renton Department of Community & Economic Development 7th Street Short Plat Administrative Report & Decision LUA19-000185, SHPL-A Report of December 3, 2019 Page 14 of 18 D_Admin Decision_7th Street Short Plat 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: Proposed Lots 1, 2, and 3 meet the minimum lot dimensional requirements in the R-8 zone, see FOF 14, Zoning Development Standard Compliance: Lot Dimensions. Lot 1 and 2 are proposed to be oriented towards NE 7th Street based on the lot width and depth dimensions.  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 project has public street frontage along NE 7th Street, which is classified as a Residential Access street. The existing right-of-way (ROW) width is approximately 60 feet. No ROW dedication is required for the proposed project. Per RMC 4-6-060, the required half street improvements include a 0.5-foot curb, 8-foot planter strip, and 5-foot sidewalk. The curb shall align with the existing curb to the west of the property. The proposed improvements are consistent with code requirements. 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 2019 transportation impact fee is $7,820.42 per new single family house. The fee in effect at the time of building permit application is applicable to this project and is payable at the time of building permit issuance.  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 east, west, north and south of the site. 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 and R-8 zoning designations. Therefore, the proposal for new single-family homes would be compatible with the existing uses in the area. 18.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. For 2019, Fire impact fees are DocuSign Envelope ID: 35719AF6-30FE-463D-BA01-F406CF7F122E City of Renton Department of Community & Economic Development 7th Street Short Plat Administrative Report & Decision LUA19-000185, SHPL-A Report of December 3, 2019 Page 15 of 18 D_Admin Decision_7th Street Short Plat applicable at the rate of $829.77 per single-family residence. This fee is paid at time of building permit issuance.  Schools: It is anticipated that the Renton School District can accommodate any additional students generated by this proposal at the following schools: Honey Dew Elementary, Risdon Middle School and Renton High School. The proposed project includes the installation of frontage improvements along the NE 7th Street frontage, including sidewalks. Any new middle school and high school students from the proposed development would be bussed to their schools. New elementary school students would walk to their school. Honey Dew Elementary is located approximately 0.52 miles from the project site at NE 8th Street and Union Ave NE. Students would walk east on NE 7th Street, east through Kiwanis Park and across Union Ave NE to the Honey Dew Elementary (See Exhibit 8). The existing shoulders and sidewalks would provide a safe walking route for students to walk to the bus stop. The bus stop for Risdon Middle School is located approximately 0.22 miles from the project site at NE 9th Ct and Redmond Ave NE. Students would walk east on NE 7th Street, across NE 7th Street at the corner of NE 7th Street and Redmond Ave NE, where they would continue north along Redmond Ave NE to where the bus stop is located. The existing shoulder would provide a safe walking route for students to walk to the bus stop. Lastly, the bus stop for Renton High School is located approximately 0.39 miles from the project site at NE 6th Street and Shelton Pl NE. Students would walk east on NE 7th Street, and would continue south along a public trail located on parcel number 0421000680 (See Exhibit 8) to where the bus stop is located. The existing shoulder, sidewalks, and trail 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 2019 School Impact Fee is $6,877.00 per new single-family residence. The fee in effect at the time of building permit application is applicable to this project and is payable at the time of building permit issuance.  Parks: A Park Impact Fee would be required for the future houses. The 2019 Parks Impact Fee is $3,945.70 per new single-family residence. The fee in effect at the time of building permit application is applicable to this project and is payable at the time of building permit issuance.  Storm Water: An adequate drainage system shall be provided for the proper drainage of all surface water. Staff Comment: A geotechnical report (Exhibit 7), dated September 28, 2018, prepared by Earth Solutions NW, was submitted with the short plat application materials. The report discusses the soil and groundwater characteristics of the site and provides recommendations for project design and construction. Geotechnical recommendations presented in the report do not support the use of infiltration devices. A Preliminary Drainage Plan and Technical Information Report (TIR; Exhibit 6), dated June 2019, prepared by CES NW, Inc., was submitted with the short plat application materials. Based on the City of Renton’s flow control map, the site falls within the Flow Control Duration Standard Area matching Forested Site Conditions and is within the Lower Cedar River Drainage Basin. The development is subject to Full Drainage Review in accordance DocuSign Envelope ID: 35719AF6-30FE-463D-BA01-F406CF7F122E City of Renton Department of Community & Economic Development 7th Street Short Plat Administrative Report & Decision LUA19-000185, SHPL-A Report of December 3, 2019 Page 16 of 18 D_Admin Decision_7th Street Short Plat with the 2017 Renton Surface Water Design Manual (RSWDM). All nine core requirements and the six special requirements have been discussed in the TIR. The project proposes a private detention vault to address the flow control requirements. The applicant proposes to convey stormwater from NE 7th Street, the internal access road, and the lot to the proposed detention and water quality system. Storm water will then be conveyed through an adjacent property to the existing conveyance system within NE 7th Pl. Any proposed detention and/or water quality vault shall be designed in accordance with the RSWDM that is current at the time of civil construction permit application. The 2019 Stormwater system development charge for each new single-family residence is $1,800.00. This is payable at construction permit issuance. A redevelopment credit of the stormwater system development charge in the amount of $1,800.00 will be applied to the existing home proposed to be demolished.  Water: Water service is provided by City of Renton. The project site is within the City of Renton’s water service area in the Highlands 565 hydraulic pressure zone. There is an existing 8-inch water main in NE 7th Street, north of the project site, that can deliver a maximum flow of 2,000 gallons per minute (gpm). 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 square feet, a minimum of 1,500 gpm fire flow would be required. A minimum of one new fire hydrant is required within 300-feet of the proposed buildings and two hydrants if the fire flow goes up to 1,500 gpm. The development is subject to a water system development charge (SDC) fee. The SDC fee for water is based on the size of the new domestic water to serve the project.

N\)rINCORPORÀTEDCIVL ENGINEERING & SURVEYINGJune25,2019City of RentonPlanning Division1055 South Grady WayRenton, V/A 98057RE: 7th Street Short Plat - Narrative for Preliminary Short Plat (CES #17234)Dear Sir or Madam:On behalf of Crowdceed, LLC, we are submitting this request for a Preliminary Short Plat. Thedevelopment involves one (1) parcel (0.64-acre), addressed 3605 NE 7th Street, Renton, WA98056, in the jurisdictional boundary of the City of Renton (King County Tax Parcel,8011100135). The Preliminary Short Plat is for three (3) single-family lots, one (l) tract, and thenecessary site development improvements, i.e. grading, utilities and roadway improvements. Theshort plat will create a net density of 6 dwelling units per acre (du/ac) with a minimum lot size of6,032 square feet and a maximum lot size of 9,280 square feet. Access to the proposed lots willbe via a 28-foot wide private access tract that will connect to NE 7th Street. Within the privateaccess tract will be a 20-foot private access drive complete with an emergency vehicleturnaround. Each of the 3 proposed lots will be accessed directly from the private access drive.The Preliminary Short Plat will require a Short Plat application and associated documents. Thefollowing documents were not included as they were signed off on the City of Renton's Vy'aiverForm: Biological Assessment, Colored Maps for Display, Environmental Checklist, FloodHazard Data, Habitat Data Report, Letter of Understanding Geological Risk, Steam or LakeStudy, and Wetlands Report/Delineation. The site is categorically exempt from Environmental(SEPA) Review, is not located within one hundred (100) feet from a stream or wetland, is notlocated inside of a floodplain or critical habitat, and no modifications are being requested.The site and surrounding parcels are zoned Residential-8 (R-8), with minimum densities of 4.0du/ac and maximum densities of 8.0 du/ac. The proposed net density for the project is 6.0 du/ac.Currently, the property is developed with an existing single-family residence and detachedgarage. Both of which will be removed as necessary to construct the proposed 3 lot short plat.As previously indicated, the site does not contain or is adjacent to any special features such as astream, wetland, floodplain, or critical habitat. However, per the City of Renton RegulatedSlopes map there are approximately 1,600 sq.ft.of sensitive slopes onsite that fall between therange of l5%o to 25%o. During site construction these slopes will be filled and eliminated duringfinal site grading.A Geotechnical Engineering Study was prepared by Earth Solutions NW (ESNW) LLC onSeptember 28,2018 to address the geotechnical issues associated with the proposed project.Paraphrasing, the "study,indicates the site is underlain primarily by glacial till. During our42e 2e'Ít' t' "tþlîå!?orÏä1["n' wÀ e8372s-s.rv.cesnrvinc.corrtEXHIBIT 10DocuSign Envelope ID: 35719AF6-30FE-463D-BA01-F406CF7F122E subsurface exploration completed on August 20, 2018, groundwater seepage was notencountered at the test pit locations." And "Based on the results of our infiltration testing andobserved variability in soil conditions, it is our opinion that neither full or limited infiltration bepursued for the subject project."Frontage improvements along NE 7th Street will consist of a half street improvement completewith new cement concrete curb and gutter, 8-foot wide planter strip, 5-foot wide cement concretesidewalk, and necessary below ground storm structures and storm pipes. The proposed curbalignment will match existing curb to the west at l6-feet south of the centerline of right of way.The frontage improvements will be constructed within the limits of the existing right of waywidth thus not requiring the need for right of way dedication. A new storm drainage extensionwill be required from the existing storm drainage system located within NE 7th Pl. in order toprovide the proposed onsite storm drainage system with a discharge location. The stormdrainage extension will extend through the existing parcel to the south of the proposed sitewithin a proposed 15-foot wide private storm drainage easement.Along with the previously mention private access drive and hammerhead turnaround, the onsiteimprovements will consist of a proposed storm drainage system that will collect and conveydeveloped stormwater runoff from the NE 7th St. half street improvements, private access drive,roof surfaces, individual driveways, sidewalks, patios, decks, landscape areas, etc. to a proposedbelow ground detention vault located within a storm drainage easement on Lot 3. The detentionvault will provide flow control for the sites proposed developed stormwater runoff. A mediafilter cartridge manhole will be provided to provide water quality treatment for the sitesdeveloped stormwater runoff. A new water main extension will extend into the site from theexisting water main located within NE 7th St. The new water main extension will consist ofapproximately 50-feet of 8-inch diameter water main with the remaining 185-feet of water mainconsisting of a 6-inch diameter water main. A new fire hydrant will be installed on the east sideof the private access drive at the north end. Each lot will be served by its own water service andmeter. In addition, each lot will be served by its own gravity side sewer that will be connected tothe existing 8-inch diameter sewer main located within NE Pierce Ct. The site will be finishedgraded to provide level pad ready lots that will require a retaining wall to be constructed alongmost of thc south and west boundary lines.We estimate the total site development construction cost at approximately $275,000. Weestimate the fair market value of the proposed 3 lot short plat at approximately $600,000. Weanticipate that proposed finish grading will require approximately 100 cubic feet of cut andapproximately 1,700 cubic feet of fill. Fill material shall be clean fill material from a nearbysource.There are 3 (20" Maple, 2'7" Fir, and 18" Fir) existing trees within public right of way along thenorth boundary of the site and I (25" Fir) existing onsite tree that will be removed as necessaryto construct the proposed offsite and onsite improvements.The proposed 3 lot short plat does not require right of way dedication in order to construct theproposed ofßite frontage improvements.P:\17234\SUBMITTALS & REVIEWS\O2 Short Plat\R0-05 - Nanative for Preliminary Short Plat.docxDocuSign Envelope ID: 35719AF6-30FE-463D-BA01-F406CF7F122E A job shack may be installed onsite during site development construction and/or home buildingconstruction.

STORM DRAINAGE COMMENTS 1. A geotechnical report dated September 28, 2018, completed by Earth Solutions NW, was provided with the Land Use Application. The report discusses the soil and groundwater characteristics of the site and provides recommendations for project design and construction. Geotechnical recommendations presented in this report do not support the use of infiltration devices. 2. CES NW, Inc. with the Land Use Application, submitted a Preliminary Drainage Plan and Technical Information Report (TIR), dated June 2019. Based on the City of Renton’s flow control map, the site falls within the Flow Control Duration Standard Area matching Forested Site Conditions and is within the Lower Cedar River Drainage Basin. The development is subject to Directed Drainage Review in accordance with the 2017 Renton Surface Water Design Manual (RSWDM). All nine Core Requirements and the six Special Requirements have been discussed in the Technical Information Report. a. General: The following general comments shall be addressed as part of the Civil Construction Permit Application: i.TIR Sections 1 and 4: The maximum impervious area allowed by zoning is 65%. It appears, based on the impervious area identified in the Preliminary Drainage Report, the proposed impervious area is less than the 65% allowed by zoning and a reduced impervious coverage is being applied to the lot given. This reduction in impervious area has implications in the projects ability to meet Core Requirement #3, #8, and #9. The use of On-site BMPs shall be fully discussed with the Technical Information Report submitted with the Civil Construction Permit Application. b. Flow Control, RSWDM Core Requirement #3: Any proposed detention and/or water quality vault shall be designed in accordance with the RSWDM that is current at the time of civil construction permit application. Separate structural plans will be required to be submitted for review and approval under a separate building permit for the detention and/or water quality vault. Special inspection from the building department is required. The project proposes a private detention vault to address the flow control requirements. The following are items that will need to be addressed as part of the Civil Construction Permit Application: i.Detention vaults must be located within a tract or easement. ii.Detention vault shall meet all building and property line setbacks required per the RSWDM. c. Conveyance, RSWDM Core Requirement #4: All new conveyance systems constructed as part of the project must be sized to RSWDM standards for the total tributary area (onsite and offsite) that the storm systems serve. The proposal will convey stormwater from NE 7th Street, internal access road, and the lot drains to the proposed detention and water DocuSign Envelope ID: 35719AF6-30FE-463D-BA01-F406CF7F122E 7th Street Short Plat– LUA19-000185 Page 4 of 7 September 19, 2019 quality system. Storm water will then be through an adjacent property to the existing conveyance system within NE 7th Pl. The following shall be fully addressed as part of the Civil Construction Permit Application: i. For conveyance pipes, an easement in compliance with table 4.1 is required to be obtained from the property owner at 3614 NE 7th PL prior to Civil Construction Permit Issuance. ii. Casings shall be provided on storm drainage piping beneath retaining walls. iii. Conveyance pipes shall be installed with setbacks in compliance with table 4.1 of the RSWDM. d. Water Quality, RSWDM Core Requirement #8: Based on the residential use of the project, Basic Water Quality Treatment is required. The project proposes to us a Contech Stormfilter Treatment System upstream of the detention vault in order to meet water quality requirements. e. When displaying the results of the WWHM analysis, the applicant shall include the full PDF report with the TIR. f. Onsite BMPs, RSWDM Core Requirement #9: Appropriate on-site BMPs will be required to help mitigate the new runoff created by this development. A preliminary drainage plan, including the application of on-site BMPs, has been included with the land use application. The final drainage plan and drainage report must be submitted with the civil construction permit application. The project proposes to utilize Soil Amendments and Perforated Stubout Connection. i.Reduced Impervious Coverage appears to be feasible and, based on the land use area proposed to design the detention system, it appears that impervious area proposed is less than the 65% allowed on each lot. ii.Additional onsite BMPs on the lots will be evaluated for feasibility as part of the single family building permit review. Basic dispersion will be evaluated more critically based on the final building layout and configuration of driveways and other impervious surfaces. 3. There is a 2019 system Development Charge of $1,800 per new single family residence. SDC fees are payable at construction permit issuance.
