There are five (5) trees located on site, of which the applicant is proposing to retain a total of two (2) trees. 8. The site is located in the Wellhead Protection Area Zone 2. 9. Approximately 215 cubic yards of material would be cut on-site and approximately 105 cubic yards of fill is proposed to be brought into the site. 10. The applicant is proposing to begin construction in spring of 2019 and end in fall of 2019. 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.  Goal L-U: Preserve, protect, and enhance the quality and functions of the City’s sensitive areas including: lakes, rivers, major and minor creeks, intermittent stream courses and their floodplains, wetlands, ground water resources, wildlife habitats, and areas of seismic and geological hazards.  Policy L-24: Manage urban forests to maximize ecosystem services such as stormwater management, air quality, aquifer recharge, other ecosystem services, and wildlife habitat. DocuSign Envelope ID: 7869B97B-3BD0-48D0-AE6C-B6D90053EB12 City of Renton Department of Community & Economic Development Gorban Short Plat Administrative Report & Decision LUA18-000627, SHPL-A Report of November 7, 2018 Page 5 of 16 D_Admin Decision_Gorban Short Plat_181107  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.  Policy L-32: Emphasize the use of open ponding and detention, vegetated swales, rain gardens, clean roof run-off, right-of-way landscape strips, open space, and stormwater management techniques that mimic natural systems, maximize water quality and infiltration where appropriate, and which will not endanger groundwater quality.  Policy L-34: Ensure buildings, roads, and other features are located on less sensitive portions of a site when sensitive areas are present.  Policy L-36: 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.  Policy L-48: Address privacy and quality of life for existing residents by considering scale and context in infill project design. Compliant if condition of approval under FOF 15 is met Policy L-55: Preserve natural landforms, vegetation, distinctive stands of trees, natural slopes, and scenic areas that contribute to the City’s identity, preserve property values, and visually define the community and neighborhoods. 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 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: Based on a net area of 16,683 square feet (18,326 square-foot gross area – 1,643 square feet of right-of-way [ROW] dedication), the proposal for two residential lots on the project site would result in a net density of 5.26 dwelling units per acre (2 lots / 0.38 acres = du/ac) which meets the minimum and maximum density requirements of 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 1 and 2. DocuSign Envelope ID: 7869B97B-3BD0-48D0-AE6C-B6D90053EB12 City of Renton Department of Community & Economic Development Gorban Short Plat Administrative Report & Decision LUA18-000627, SHPL-A Report of November 7, 2018 Page 6 of 16 D_Admin Decision_Gorban Short Plat_181107 Proposed Lot Lot Size (sq. ft.) Lot Width (ft.) Lot Depth (ft.) Lot 1 7,971 60.4 132 Lot 2 8,712 66 132 Staff Comment: All lots will comply with the lot dimension standards of the R-8 zone. 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: All lots have sufficient building area to develop a single-family home and comply with the setbacks of the zone. Setbacks would be verified at the time of building permit review. If retained, the existing residence and shed would not comply with Residential-8 (R-8) setback requirements. Therefore, staff recommends as a condition of approval that the applicant obtain a demolition permit and complete a final inspection from the City for the removal of the residence and shed located on proposed Lots 1 and 2 in order to comply with Residential-8 (R-8) setbacks of the zone prior to final plat approval.  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: Building height, building coverage, and impervious surface coverage for the new single-family residences would be verified at the time of building permit review.  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 DocuSign Envelope ID: 7869B97B-3BD0-48D0-AE6C-B6D90053EB12 City of Renton Department of Community & Economic Development Gorban Short Plat Administrative Report & Decision LUA18-000627, SHPL-A Report of November 7, 2018 Page 7 of 16 D_Admin Decision_Gorban Short Plat_181107 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, prepared by Eccos Design (see Exhibit 3), was submitted with the short plat application. A 10-foot on-site landscape strip is proposed along the street frontage of NE 28th St. A Plant Schedule was included on the Landscape Plan with the following trees and plants proposed within the on-site landscape strip and ROW: Dwarf Purple-leaf Barberry, Vanessa Parrotia (within ROW), Dwarf Burning Bush, Emerald Gaiety, Firepower Nandina, Dwarf Mugo Pine, Blue Oat Grass, and Kinnikinnick grass. In addition, two street trees are proposed within the ROW fronting each lot for a total of four street trees. Therefore the Conceptual Landscape Plan is compliant with RMC 4-4-070. Compliance with on-site landscaping would be reviewed at the time of building permit application for each lot. 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 total of five (5) significant trees were identified on the Tree Retention plan and in the Arborist Report prepared by A.B.C. Consulting Arborists LLC (see Exhibits 3 and 4). During review, staff discovered discrepancies between the tree retention plan and the Arborist Report related to tree retention. For example, the Arborist Report identifies a 16.5-inch caliper Cherry tree on proposed Lot 1 that is diseased and not viable for retention, while the Tree Retention plan shows the tree as retained. In addition, the Arborist Report identifies a 35.5-inch caliper Douglas fir tree for retention on proposed Lot 2 near the rear of the property. However, the Tree Retention plan identifies the Douglas fir, a landmark tree, as a tree proposed for removal. Due to the discrepancies between the two documents, staff was unable to review for compliance with the tree retention regulations. The Arborist Report recommends a number of tree protection measures related to protection fencing for on-site and off-site trees, canopy pruning, and excavation for utilities. In order to maximize the survival rate of retained on- and off-site trees, staff recommends as a condition of approval that the applicant DocuSign Envelope ID: 7869B97B-3BD0-48D0-AE6C-B6D90053EB12 City of Renton Department of Community & Economic Development Gorban Short Plat Administrative Report & Decision LUA18-000627, SHPL-A Report of November 7, 2018 Page 8 of 16 D_Admin Decision_Gorban Short Plat_181107 follow the recommendations contained in the Arborist Report prepared by A.B.C. Consulting Arborists LLC and dated September 28, 2018. In order to comply with the proposed priority order for retained trees and reconcile the discrepancies, staff recommends as conditions of approval that the applicant be required to retain the 35.5-inch caliper Douglas fir landmark tree on proposed Lot 2 and submit an updated Tree Retention plan and Arborist Report that both demonstrate compliance with the tree retention and density regulations. Each lot should provide a minimum of three trees (either existing or new) in order to comply with the tree density regulations. Trees designated as street trees do not count towards the minimum tree density requirement.  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 4-4-80 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. N/A 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 has not proposed any new retaining walls, fences, or hedges as part of the property. 15. Design Standards: Residential Design and Open Space Standards (RMC 4-2-115) are applicable in the R- 4, R-6, 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 Design Standards R-8 and Analysis Compliance not yet demonstrated Garages: If an attached garage is wider than twenty six feet (26’), at least one (1) garage door shall be recessed a minimum of four feet (4’) from the other garage door.

The proposal is consistent with the following subdivision regulations if all conditions of approval are complied with: DocuSign Envelope ID: 7869B97B-3BD0-48D0-AE6C-B6D90053EB12 City of Renton Department of Community & Economic Development Gorban Short Plat Administrative Report & Decision LUA18-000627, SHPL-A Report of November 7, 2018 Page 11 of 16 D_Admin Decision_Gorban Short Plat_181107 Compliance Subdivision Regulations and Analysis  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 access each lot with individual driveways off of NE 28th St. Alley access was determined by staff to be unfeasible for the proposed project due to the lack of available ROW at the rear of the property. Driveways shall be designed in accordance with RMC 4-4-080. 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. 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 and 2 meet the minimum lot dimensional requirements in the R-8 zone.  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: Access to the proposed project would be provided by one driveway per lot off of NE 28th St. The existing ROW width of NE 28th St is approximately 40 feet. To meet the City’s complete street standards, a minimum ROW width of 53 feet is required. The applicant has submitted a request for Fee in Lieu of Street Improvements (Exhibit 5). Due to the existing street pattern within the neighborhood, staff recommends 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.

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 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 2018, Fire impact fees are 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: Kennydale Elementary, Risdon Middle School and Hazen High School. Any new students from the proposed development would walk to the elementary school and would be bussed to middle and and high schools. The bus stop is located approximately 100 feet from the project site at the NE corner of Blaine Ave NE and NE 28th St. Students would cross NE 28th St at the interaction in order to reach the bus stop. Kennydale Elementary is located approximately 0.5 miles away from the project site. When walking to school, students would walk along the south side of NE 28th St where there is a wide shoulder. Students would then cross Aberdeen Ave NE at the four-way stop and continue walking along an unimproved section of NE 28th St that extends all the way to the intersection of Kennewick Pl NE and NE 28th St, directly across from Kennydale Elementary. A designated pathway is located within the unimproved ROW and is only accessible for bikes and pedestrians. A crossing guard is present at the intersection before and after school allowing safe passage for the students across the intersection and onto school grounds. 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 fee is payable to the City as specified by the Renton Municipal Code. For 2018, School impact fees are applicable at the rate of $5,643.00 per single-family residence. This fee is paid at time of building permit issuance.  Parks: A Park Impact Fee would be required for the future houses. For 2018, Park Impact Fees are applicable at a rate of $2,740.07 per single-family residence. This fee is payable at the time of building permit issuance.

Staff Comment: According to the Geotechnical Report, dated June 8, 2018 and prepared by Cobalt Geosciences (see Exhibit 8), the project site is nearly level and is primarily vegetated with grass, bushes, and multiple deciduous/evergreen trees. A single test pit, dug to depth of three feet, discovered 12 inches of topsoil underlain by approximately two feet of loose to medium dense grinded sand with traces of gravel. Two hand borings dug to a depth of three and a half feet in the northeast and southwest corners of the property yielded similar results. Groundwater was not encountered during testing. The report concluded that soil erosion potential on the site can be mitigated through landscaping and surface water runoff control. Measures recommended to be employed during construction include installing silt fences, hay bales, mulching, control ditches, and diversion trenches. In order to ensure all measures proposed by the geotechnical engineer are implemented related to soil erosion and the foundation, staff recommends as a condition of approval the applicant comply with all recommendations found in the submitted Geotechnical Report. A Preliminary Drainage Plan and Technical Information Report (TIR), dated September 5, 2018 and prepared by Offe Engineers, PLLC, was submitted with the Land Use Application (see Exhibit 6). Based on the City of Renton’s flow control map, the site falls within the Flow Control Standards Forested site conditions and is located within the Lower May Creek Drainage Basin. During review by staff, the report was found to be missing information and specifically does not address Core Requirements 7, 6, and 9 in the 2017 Renton Surface Water Design Manual. All nine core requirements and the six special requirements need to be discussed in the final Technical Information Report submitted at the time of Construction Permit application. In addition, appropriate on-site BMPs designed to mitigate for new runoff created by the development will need to be identified on the final drainage plan and report submitted at the time of Construction Permit application. The Stormwater system development charge for each new single-family residence is $1,718.00. This is payable at construction permit issuance. A redevelopment credit of the stormwater system development charges in the amount of $1,718.00 will be applied to the existing home proposed to be demolished.  Water: 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 fire hydrant is required within 300-feet of the proposed buildings and two hydrants if the fire flow goes up to 1,500 gpm. In order to provide adequate fire protection and to conform to City of Renton Code and Development Standards, the following improvements will be required: Each home shall be installed with a fire sprinkler system with a double check valve assembly (DCVA) for backflow prevention per the requirements of the Renton Regional Fire Authority.  Sanitary Sewer: The existing home is served by a private on-site septic system. The septic system shall be abandoned in accordance with King County Department of Health regulations and Renton Municipal Code.

SDC fee for sewer is based on the size of the new domestic water to serve the project. The current sewer fee for a 1-inch meter install is $2,837.00 per meter. Each lot shall have a separate side sewer stub. I. CONCLUSIONS: 1.

Dear Staff: We are applying for a waiver (fee in lieu of) for curbs, gutters, sidewalks and street drainage along NE 28th ST, Gorban Short Plat. There are no such improvements along the south side of NE 28th ST in this area. RMC Section 4-9-060 allows for a waiver (fee in lieu of) for street improvements under special conditions. Justification for the waiver (fee in lieu of) is as follows: a. NE 28th ST. street has no curbs, gutters, sidewalks or storm drainage along the south side of the street. The lots to the east and west are developed with single family residences on each lot at this time. b. No construction plans have been created for such improvements. The amount of material or costs are not determined. c. Construction of curbs, gutters, sidewalks and drainage improvements for such a short distance will create a hazard since there are no such adjacent improvements, to the east or west of the site. A coordinated design is needed for improvements for the entire street in the future. d. No adverse impacts will occur to other properties in the area since the street will remain usable as it is now. A ten foot landscape strip will be provided for the lot frontage on the street. The newly dedicated right of way will be landscaped. Please review the application and if additional information is needed or if you have any questions please contact us.
