CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2021\PRE21-000012 DEPARTMENT OF COMMUNITY AND ECONOMIC DEVELOPMENT M E M O R A N D U M DATE:February 2, 2021 TO:Pre-Application File No. 21-000012 FROM:Angelea Weihs, Associate Planner SUBJECT:Meng 13th Short Plat – East of 1301 Lincoln Pl NE (Parcel number 3343902559) General: We have completed a preliminary review of the pre-application for the above- referenced development proposal. The following comments on development and permitting issues are based on the pre-application submittals made to the City of Renton by the applicant and the codes in effect on the date of review. The applicant is cautioned that information contained in this summary may be subject to modification and/or concurrence by official decision-makers (e.g., Hearing Examiner, Community & Economic Development Administrator, Public Works Administrator, Planning Director, and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. The applicant is encouraged to review all applicable sections of the Renton Municipal Code. The Development Regulations are available online at https://www.codepublishing.com/WA/Renton/. Project Proposal: The subject property (Parcel number 3343902559) is located to the east of 1301 Lincoln Pl NE. The parcel has frontage on NE 13th Street and is located within the R-8 Zone. The site area is approximately 27,126 sf (0.62 acres) and is currently vacant. The proposal is to subdivide the property into 4 lots. The applicant proposes to access proposed Lots 1 and 2 via a new improved public half-street and cul-de-sac on NE 13th Street. Access for lots 3 and 4 is proposed via a private access easement extending from the NE 13th Street cul-de-sac. The property also abuts Lincoln PL NE, which is a private street that runs along the west property line. The proposed lots range in size from 5,387 SF to 5,598 SF in size. Wellhead Protection Area Zone 2 is mapped on the project site. No other critical areas are mapped on the project site. Current Use: The property is currently vacant. Zoning/Density Requirements: The subject property is located within the Residential-8 (R-8) zoning classification. The density range allowed in the R-8 zone is a minimum of 4.0 to a maximum of 8.0 dwelling units per 1 net acre. The Residential Medium Density Land Use designation is intended to implement the R-8 zone. 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. Detached single family residential dwelling units are permitted uses within the R-8 zoning designation. Meng 13th Short Plat, PRE21-000012 Page 2 of 6 February 4, 2021 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2021\PRE21-000012 Density: The area of public and private streets and critical areas would be deducted from the gross site area to determine the “net” site area prior to calculating density. In order to calculate the proposed density of the project, any area of public road, private driveway/easement, and/or critical area dedication must be known. All fractions which result from net density calculations shall be truncated at two (2) numbers past the decimal (e.g., 4.5678 becomes 4.56). Calculations for minimum or maximum density that result in a fraction that is 0.50 or greater shall be rounded up to the nearest whole number. Those density calculations resulting in a fraction that is less than 0.50 shall be rounded down to the nearest whole number. Based on the gross land area of 27,126 square feet, the 4-lot proposal arrives at a gross density of approximately 6.4 du/ac (4 lots / 0.62 gross acres = 6.4 du/ac). Based on the gross density of 6.4 du/ac, the subject site would meet the minimum density requirements of the zone. The applicant would be required to demonstrate compliance with the net density requirements of the zone at the time of formal application, after deduction of ROW dedication and any access tracts. Development Standards: The project would be subject to RMC 4-2-110A, “Development Standards for Single Family Zoning Designations” effective at the time of complete application (noted as “R-8 standards” herein). Minimum Lot Size, Width and Depth – The minimum lot size permitted in the R-8 zone is 5,000 square feet for parcels being subdivided. Minimum lot width is 50 feet for interior lots and 60 feet for corner lots; minimum lot depth is 80 feet. Please note that for short plats of parcels smaller than one acre, one parcel may be allowed to be smaller than the required minimum lot size, if all other parcels meet the required minimum lot size standard of the zone. In the R-8 zone, one parcel may be allowed to be four thousand five hundred (4,500) square feet. Lot depth shall be the horizontal distance between the front and rear lot lines, measured from midpoint to midpoint; except in the case of flag lots and irregularly shaped lots. For flag lots, the “flagpole” portion of the lot shall be ignored for the purpose of calculating lot depth. For irregularly shaped lots and lots without an obvious rear lot line, the lot depth shall be measured to the midpoint of an imaginary line at least fifteen feet (15') in length located entirely within the lot and farthest removed and parallel to the front lot line or its tangent. Based on the pre-application submittal provided by the applicant, proposed lots 1-4 appear to comply with minimum lot size requirements; however, the square footage provided does not account for the shared driveway tract, which must be deducted from lot area. All proposed lots appear to comply with lot width requirements. Lots 1 and 2 do not appear to comply with lot depth requirements based on the lot depth measurement requirements identified above. The applicant will need to demonstrate compliance with the minimum lot size, width and depth criteria of the zone (following deduction of required ROW dedication, including the required cul-de-sac), based on the definitions of lot size, width, and depth (RMC 4-11-120), at the time of formal land use application. Building Standards – The R-8 standards allow a maximum building coverage of 50% of the lot area. The maximum impervious coverage in the R-8 zone is 65%. The maximum wall plate height is restricted to 24 feet, and the buildings shall be not more than two stories. 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; common rooftop features, such as chimneys, may project an additional four (4) vertical feet from the roof surface. Non-exempt vertical projections (e.g., decks, railings, etc.) shall not extend above the maximum wall plate height unless the projection is stepped back one-and-a-half (1.5) horizontal feet from each façade for each one (1) vertical foot above the Meng 13th Short Plat, PRE21-000012 Page 3 of 6 February 4, 2021 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2021\PRE21-000012 maximum wall plate height. The maximum wall plate height for detached accessory structures is 12 feet. The gross floor area must be less than that of the primary structure. Accessory structures are also included in building lot coverage calculations. The new single family homes would need to comply with the maximum building coverage, impervious surface requirements, and building height regulations of the zone at the time of building permit review. Setbacks – Setbacks are the minimum required distance between the building footprint and the property line. The required setbacks for the R-8 zone are: Front yard: 20 feet for the primary structure; Rear yard: 20 feet; Side yards: 5 feet; and Side yards along streets: 15 feet. Side yard along a street is defined as the yard requirement that is neither a front yard nor a rear yard, yet it abuts a street right-of-way or private street. New single family homes must comply with the secondary front yard setback requirements from the both private street (Lincoln PL NE) and the proposed shared driveway. Based on the provided site plan, the proposed structures do not comply with the front or secondary front yard setback requirements. Compliance with required setbacks for the new single family homes would be verified at the time of building permit application. Access/Parking: The applicant proposes to access proposed Lots 1 and 2 via a new improved public half-street and cul-de-sac, NE 13th Street. Access for lots 3 and 4 is proposed via a private access easement extending from the NE 13th Street cul-de-sac. Shared driveways may be allowed for access to four (4) or fewer residential lots, provided: a. At least one of the four (4) lots abuts a public right-of-way and the street frontage of the lot is equal to or greater than the lot width requirement of the zone; b. The subject lots are not created by a subdivision of ten (10) or more lots; c. A public street is not anticipated by the City of Renton to be necessary for existing or future traffic and/or pedestrian circulation through the short subdivision or to serve adjacent property; d. The shared driveway would not adversely affect future circulation to neighboring properties; e. The shared driveway is no more than three hundred feet (300') in length; and f. The shared driveway poses no safety risk and provides sufficient access for emergency vehicles and personnel. Shared driveways shall be within a tract; the width of the tract and paved surface shall be a minimum of sixteen feet (16'); the Fire Department may require the tract and paved surface to be up to twenty feet (20') wide. If a shared driveway abuts properties that are not part of the subdivision, an eight foot (8') wide landscaped strip shall be provided between the shared driveway and neighboring properties. The landscape strip shall be within a tract and planted with a mixture of trees, shrubs, and groundcover. The shared driveway may be required to include a turnaround per subsection H of RMC 4-6-060. The maximum grade for the shared driveway shall not exceed fifteen percent (15%), except for within approved hillside subdivisions. The driveway slopes cannot exceed 15%. If the grade exceeds 15%, a variance is required. The maximum width of single loaded garage driveways shall not exceed 9 feet and double loaded garage driveways shall not exceed 16 feet. Compliance with driveway standards would Meng 13th Short Plat, PRE21-000012 Page 4 of 6 February 4, 2021 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2021\PRE21-000012 be verified at the time of building permit review. Each lot is required to accommodate off street parking for a minimum of two vehicles. The proposed shared driveway is not located within a tract. The proposal would need to be revised to comply with the shared driveway requirements. Compliance with the shared driveway and access standards would be verified at the time of formal land use application. Compliance with driveway and parking standards would be verified at the time of building permit review. Landscaping: With the exception of critical areas, all pervious area shall have landscape treatment. Landscaping may include hardscape such as decorative paving, rock outcroppings, fountains, plant containers, etc. Ten feet (10') of on-site landscaping is required along all public street frontages, with the exception of areas for required walkways and driveways and those zones with building setbacks less than ten feet (10'). In those cases, ten feet (10') of landscaping shall be required where buildings are not located. 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 (2) trees are to be located in the front yard prior to final inspection. A conceptual landscape plan shall be provided with the formal land use application as prepared by a registered Landscape Architect, a certified nurseryman or other certified professional. Significant Tree Retention: An aerial image of the site identifies mature trees on the site. If significant trees (greater than 6-inch caliper or 8-caliper inches for alders and cottonwoods) are proposed to be removed, a tree inventory and a tree retention plan along with an arborist report, tree retention plan and tree retention worksheet shall be provided with the formal land use application as defined in RMC 4-8-120. The tree retention plan must show preservation of at least 30% of significant trees. The Administrator may authorize the planting of replacement trees on the site if it can be demonstrated to the Administrator's satisfaction that an insufficient number of trees can be retained. Please refer to Tree Retention and Land Clearing Regulations RMC 4-4-130 for further general and specific tree retention and land clearing requirements. In addition to retaining 30% of existing significant trees, each new lot would be required to provide a minimum tree density of 2 trees per 5,000 square feet of lot area onsite. Protected trees that do not contribute to a lot's required minimum tree density shall be held in perpetuity within a tree protection tract. 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. The Administrator may require independent review of any land use application that involves tree removal and land clearing at the City's discretion. Meng 13th Short Plat, PRE21-000012 Page 5 of 6 February 4, 2021 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2021\PRE21-000012 If staff determines that the trees cannot be retained, replacement trees, with at least a 2-inch caliper or an evergreen at least 6 feet tall, shall be planted at a rate of 12 caliper inches of new trees to replace each protected tree removed. A formal tree retention plan prepared by an arborist or landscape architect would be reviewed at the time of the Short Plat application. Fences/Walls: If the applicant intends to install any fences or retaining walls as part of this project, the location must be designated on the landscape plan or grading plan.
