There are approximately 106 trees located on site of which the applicant is proposing to retain a total of 28 trees. 8. High and moderate coal mine hazard areas, a 30,445 square foot Category 4 wetland with a standard 50- foot buffer, and sensitive slopes have been identified on the project site. 9. Approximately 720 cubic yards of material would be cut and 720 cubic yards of fill would be required for the grading of the driveways for the new lots. 10. The applicant is proposing to begin construction in Summer/Fall of 2018 and end in Fall/Winter of 2018/2019. 11. No public or agency comments were received during the 14 day public comment period. 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  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-T: Create a functioning and exemplary urban forest that is managed at optimum levels for canopy, health, and diversity.  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-29: Minimize erosion and sedimentation in and near sensitive areas by requiring appropriate construction techniques and resource practices, such as low impact development.

Development activities shall not decrease the net acreage of existing wetlands.  Policy L-32: Protect buffers along wetlands and surface waters to facilitate infiltration and maintain stable water temperatures, provide for biological diversity, reduce amount and velocity of run-off, and provide for wildlife habitat.  Policy L-35: Ensure buildings, roads, and other features are located on less sensitive portions of a site when sensitive areas are present.  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.  Policy L-49: Address privacy and quality of life for existing residents by considering scale and context in infill project design. 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 4-2-110A, 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. Phasing, shadow platting, or land reserves may be used to satisfy the minimum density requirements if the applicant can demonstrate that the current development would not preclude the provision of adequate access and infrastructure to future development and would allow for the eventual satisfaction of minimum density requirements through future development. In the event the applicant can show that minimum density cannot be achieved due to lot configuration, lack of access, environmental or physical constraints, minimum density requirements may be waived. Staff Comment: After the deduction of the 30,170 square foot wetland area from the 114,806 square foot gross site area, the project site would have a net area of 84,636 square feet or 1.94 net acres. The proposal for 2 lots on the 1.94 net acre site would result in a net density of 1.03 du/net acre, which is less than the minimum density DocuSign Envelope ID: 0B8CC495-C434-4FB0-AE78-8D4954686601 City of Renton Department of Community & Economic Development Administrative Report & Decision CHERIE LANE SHORT PLAT LUA16-000964 April 27, 2018 Page 6 of 17 D_Admin_Report_180427 required in the R-8 zone. Staff recommends the waiver of the minimum density requirement, consistent with RMC 4-2-110D1.b for this project due to the location of Wetland A within the center portion of the project site, and the high and medium coal mine hazard areas which significantly constrain the available developable area onsite.  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 1-2 and Tract A. Proposed Lot Lot Size (sq. ft.) Lot Width (feet) Lot Depth (feet) Lot 1 10,665 60 166 Lot 2 40,190 166 172 Tract A 36,951 N/A N/A Staff Comment: As proposed, all lots would comply with the minimum lot size, width, and depth requirements of the R-8 zone.  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 contain adequate area for compliance with the required setbacks. Compliance with setbacks would be verified 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: 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 DocuSign Envelope ID: 0B8CC495-C434-4FB0-AE78-8D4954686601 City of Renton Department of Community & Economic Development Administrative Report & Decision CHERIE LANE SHORT PLAT LUA16-000964 April 27, 2018 Page 7 of 17 D_Admin_Report_180427 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. A 15-foot wide landscape strip is required around the perimeter of any stormwater facility. The 15-foot wide landscape strip is required to be located within the stormwater tract and outside the perimeter of any fencing around the facility. Staff Comment: A Conceptual Landscape Plan was not submitted with the project application materials. A 10-foot onsite landscape strip is required along all street frontages (Talbot Rd S and S 34th Pl) and two trees are required in the front yard for lots that do not have public street frontage (Lot 2). Staff recommends, as a condition of approval, that a detailed landscape plan meeting the requirements of RMC 4-8-120D.12 be submitted at the time of Construction Permit review for review and approval by the Current Planning Manager. Compliant if condition of approval is 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. Trees required to be retained (i.e., protected trees), and/or Administrator approved replacement trees (excluding required street trees pursuant to RMC 4-4-070F, Areas Required to be Landscaped), 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; however, multiple tree protection tracts may be approved if it can be demonstrated, to the Administrator’s satisfaction, that multiple tracts provide a better site design and/or support other adopted goals and purposes of this Title. Staff Comment: A Conceptual Tree Retention Plan (Exhibit 10) was included with the project application. According to the submitted plan, a total of 106 significant trees were DocuSign Envelope ID: 0B8CC495-C434-4FB0-AE78-8D4954686601 City of Renton Department of Community & Economic Development Administrative Report & Decision CHERIE LANE SHORT PLAT LUA16-000964 April 27, 2018 Page 8 of 17 D_Admin_Report_180427 identified on the project site, 7 trees have been identified as dangerous and 46 trees are located within critical areas and/or buffer areas, resulting in 107 protected trees. Based on the City’s retention requirement of 30 percent (30%) the applicant would be required to retain or replace 32 trees on the project site. The applicant has identified 28 trees as viable for retention; therefore the applicant would be required to mitigate for the removal of 4 significant trees. Based on a replacement ratio of 6 minimum 2 inch caliper replacement trees for every protected tree removed, a total of 24 minimum 2 inch caliper replacement trees would be required to be planted on the project site. In addition, each lot would be required to provide the minimum two (2) trees required per 5,000 square feet for compliance with the minimum tree density requirements. It appears that protected or replacement trees would be required on the project site that would exceed the minimum tree density requirements for each of the new lots. Tree protection tracts are required for protected trees that do not count towards a lots minimum tree density requirements. The applicant may extend the boundaries of the Native Growth Protection Area Tract (NGPA) to include additional protected trees. Staff recommends, as a condition of approval, that a final Tree Retention and Replacement Plan be submitted at the time of Construction Permit application for review and approval by the Current Planning Project Manager. The final Tree Retention and Replacement Plan shall include the planting of a minimum of 24 minimum 2 inch caliper replacement trees and a minimum of two trees per 5,000 square feet of lot area for compliance with the minimum tree density requirements and shall include a tree protection tract for those trees that do not count towards an individual lot’s minimum tree density requirements. The NGPA tract may be extended to encompass the additional protected trees, if feasible.  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 new lot would contain adequate area for compliance with the minimum parking requirements. Compliance with parking would be verified at the time of Building Permit review for the new single-family residences.  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: A maximum 4-foot high rockery retaining wall is proposed along the north and south sides of the driveway access proposed to serve Lot 2, which would comply with the maximum height requirements for retaining walls.

If masonry siding is used, it shall wrap the corners no less than twenty four inches (24"). Staff Comment: Compliance with this standard would be verified at the time of Building Permit review. 16. 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 (delete those critical areas that are not located on or near the site): 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: Coal mine hazard areas are mapped on the project site. The applicant submitted a Coal Mine Hazard Assessment, prepared by Icicle Creek Engineers, Inc., dated December 27, 2016 (Exhibit 7) that evaluated and rated the onsite coal mine hazard areas and provided recommendations for development on and around the coal mine hazard areas. The report identified four abandoned underground coal mines underneath the project site. All the mines were developed by opening a “slope” down the coal seam that served as the main haulageway for coal to the surface. From the main haulageway, “chutes” (or tunnels) were driven up the coal seam toward the ground surface. These chutes were then connected by a series of “cross-cuts” (tunnels that connect the chutes). This type of mining is referred to as “room-and-pillar” mining. Upon retreat from the mine, the support pillars of coal between the chutes and cross- cuts were removed (called “pillar-robbing”) to maximize the removal of coal from the mine. The effect of pillar-robbing was to dramatically destabilize the mined-out area, therefore, natural collapse (“room caving”) of the mine usually occurred within a few weeks or years. Subsurface conditions of the project site were explored by drilling 19, three-inch diameter borings (B-1 through B-19) to depths ranging from 35 to 95 feet below ground surface. Three high coal mine hazard areas have been identified within proposed Lot 2. No development is recommended over these high coal mine hazard areas, unless the area is “bridged” (structurally spanned) or additional subsurface exploration is completed in order to develop alternative mitigation, as the risk of sink hole occurrence in these areas is high. DocuSign Envelope ID: 0B8CC495-C434-4FB0-AE78-8D4954686601 City of Renton Department of Community & Economic Development Administrative Report & Decision CHERIE LANE SHORT PLAT LUA16-000964 April 27, 2018 Page 12 of 17 D_Admin_Report_180427 Moderate coal mine hazard areas have been identified on the central portion of proposed Lot 2 traversing the site from northwest to southeast. In these areas, the risk of sinkhole occurrence is low to moderate. Roads, driveways, outbuildings (sheds), yard and passive use should be allowed in the moderate coal mine hazard areas. Low coal mine hazard areas have been identified on the southwest corner of proposed Lot 2. The development of structures, with mitigation, may be allowed in the low coal mine hazard areas. Recommended mitigation for development in low coal mine hazard areas includes: Small, square or nearly square-shaped building pads should be favored over large, irregularly-shaped building pads; use of rigid foundations (conventional reinforced-concrete spread footings) supporting a flexible superstructure (wood- frame), foundations should extend across the inside of the building footprint rather than using individual column footings; crawl-space construction rather than slab-on- grade (slab-on-grade may be used in garage areas); no brick or basement construction; underground utilities should be designed with flexible and/or telescopic couplings or fittings; ICE should be contacted immediately should house distortion or a ground surface sag/sinkhole be observed; and prospective owners that may occupy structures within Lower Risk High Coal Mine Hazard areas should be made aware that an abandoned underground coal mine exists at a depth of 50+ feet although subsurface exploration suggests that the abandoned mine working have filled with coal and rock fragments or have otherwise collapsed. Staff recommends, as a condition of approval, that development on the project site comply with the recommendation provided in the Coal Mine Hazard Assessment, prepared by Icicle Creek Engineers, Inc., dated December 27, 2016. Staff further recommends, that a note be recorded on the face of the final short plat map identifying and delineating the coal mine hazard areas on the project site.  Wetlands: The following buffer requirements are applicable to wetlands in accordance with RMC 4-3-050G.2: Wetland Category Buffer Width Structure Setback beyond buffer High Habitat Function (8-9 points) Moderate Habitat Function (5-7 points) Low Habitat Function (3-4 points) All Other Scores 15 ft.

One wetland (Wetland A) has been identified on the project site. Two other wetlands have been identified off-site with associated buffers that extend onto the project site. One off-site wetland is located to the southeast of the project site and a second off-site wetland has been identified off-site to the northeast. Wetland A is classified as a Category IV wetland with a 50-foot buffer, the off-site wetland to the southeast has been classified as a Category III wetland with a 75-foot buffer and the off-site wetland to the northeast has been classified as a Category IV wetland with a 50-foot buffer. No impacts are proposed to the wetland or buffer areas. All onsite wetland and buffer areas are proposed to be located within a Native Growth Protection Area tract (Tract A). The tract is required to be identified with a split rail fence and NGPE signage. The fence and signage shall be installed prior to short plat recording. 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  Access: Each lot must have access to a public street or road. Access may be by a shared driveway per the requirements of the street standards. Alley loaded access is the preferred street pattern. 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: Proposed Lot 2 would access off of Talbot Road S via an existing pipestem. Proposed Lot 1 has frontage on S 34th Pl and would access the public right-of-way via a driveway. Alleys are not proposed within the proposed short plat layout. Staff has reviewed the proposed lot layout and determined that the use of an alley layout would be infeasible due to the location of the wetland on the central portion of the project site. N/A Blocks: Blocks shall be deep enough to allow two tiers of lots. Staff Comment: Not applicable, no blocks are proposed. 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: Talbot Road South is classified as a Collector Arterial with an existing right-of-way (ROW) width of 60 feet. As per RMC 4-6-060 the minimum ROW width required on a minor arterial is 83 feet for 2 lanes (94 feet for 3 lanes) with street improvements. Per RMC 4-6-060, half street frontage improvements will be required to be built along Talbot Road frontage, including paving, curb and gutter, 8-foot wide planter strip with street trees, and sidewalk. Right of way dedication of 11.5 feet is required. The required improvements were not included on the submitted plans. The applicant may submit a street modification, to reduce the required frontage improvements and/or right-of-way dedication for Talbot Road. Staff recommends, as a condition of approval, that the applicant include the required frontage improvements along Talbot Road S on the construction plan submittal or submit a modification request and obtain approval of the modification to reduce the required improvements along DocuSign Envelope ID: 0B8CC495-C434-4FB0-AE78-8D4954686601 City of Renton Department of Community & Economic Development Administrative Report & Decision CHERIE LANE SHORT PLAT LUA16-000964 April 27, 2018 Page 14 of 17 D_Admin_Report_180427 Talbot Road S The modification request or revised civil plans shall be submitted at the time of Construction Permit review to the City’s Plan Reviewer for review and approval. S 34th Pl is classified as a Residential Access Street, per RMC 4-6-060, half street frontage improvements will be required to be built along the S 34th Pl frontage, including paving, curb and gutter, 8-foot wide planter strip with street trees, and sidewalk. Each new lot is subject to a Transportation Impact Fee. The 2018 Transportation Impact Fee is $5,430.85 per single-family home. The Transportation Impact Fee is due at the time of Building Permit issuance for each individual home.  Relationship to Existing Uses: The proposed project is compatible with existing surrounding uses. Staff Comment: The surrounding properties are developed with detached single-family residences and the proposal would be compatible with the surrounding development. 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. The 2018 fire impact fees are applicable at the rate of $495.10 per single family unit. The current fee at building permit application would be assessed and 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: Talbot Hill Elementary, Dimmit Middle School and Renton High School. Students attending Talbot Hill Elementary would walk to school along the following route: north for 0.8 miles along the existing shoulder/sidewalks along Talbot Rd S to Talbot Hill Elementary. Any new students attending Dimmit Middle or Renton High Schools from the proposed development would be bussed to their schools. The stop is located approximately 0.12 miles from the project site at Talbot Rd S and S 32nd St. Students would walk to the north along Talbot Rd S to the intersection of S 32nd street to wait for the bus. 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. Currently the fee is assessed at $6,432.00 per single family residence.  Parks: A Park Impact Fee would be required for the future houses. The current Park Impact Fee is $2,740.07. 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 preliminary drainage plan (Exhibit 9) and Technical Information Report (TIR) prepared by Encompass Engineering dated March 27, 2018 (Exhibit 8) was submitted with the short plat application materials. The site is located in the City’s Flow Control Duration Standard (Forested Site Conditions).
