M E M O R A N D U M DATE:March 21, 2022 TO:Clark Close, Senior Planner FROM:Corey Thomas, Lead Plans Review Inspector SUBJECT:Young Short Plat and Townhomes Comments based on the assumption that these units will be built under the International Residential Code. Starting February 1st, 2021, townhomes over 4 units will require sprinklers per state amendment. 1. The fire flow requirement for single-family homes 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. The fire flow requirements for the townhomes is 2,500 gpm if built with non-rated construction and no fire sprinklers. Three fire hydrants are required. One within 150-feet and two within 300-feet of each of the proposed buildings. Fire sprinklers systems may be needed due to limited fire flow availability in this area. 2. The fire impact fees are applicable at the rate of $829.77 per townhome or single family unit. This fee is paid at building permit issuance. Credit will be granted for the removal of the tow existing homes. 3. Fire department apparatus access roadways are required to be a minimum of 20-feet wide fully paved, with 25-feet inside and 45-feet outside turning radius. Fire access roadways shall be constructed to support a 30-ton vehicle with 75-psi point loading. Access is required within 150-feet of all points on the buildings. Dead end streets that exceed 150-feet in length require an approved turnaround. An approved hammerhead type turnaround would meet minimum requirements. Maximum grade is 15 percent.

CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2022\PRE22-000079 DEPARTMENT OF COMMUNITY & ECONOMIC DEVELOPMENT M E M O R A N D U M DATE:April 7, 2022 TO:Pre-application File No. 22-000079 FROM:Clark H. Close, Senior Planner SUBJECT:Young Preliminary Plat – 8047 and 8055 S 130th St 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, Development Services 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 www.rentonwa.gov. Project Proposal: The project site is on three (3) properties located within the West Hill Community Planning Area in the City of Renton at the intersection of S 130th St and Renton Ave S at 8047 and 8055 S 130th St (APNs 2144800306, 2144800305, and 2144800300). According to King County Department of Assessments, the total site area is approximately 60,917 square feet (1.4 acres). Two (2) properties are located in the Residential-8 (R-8) zone and are designated Residential Medium Density in the Comprehensive Plan (APNs 214480-0306 and -0305). One (1) property is located in the Residential – 14 du/ac (R-14) zone and is designated Residential High Density in the Comprehensive Plan (APN 2144800300). The applicant is proposing to create 15 total dwellings units on 15 lots – five (5) 2 story single family detached homes on the R-8 zoned parcels and two (2) 2 story triplex townhomes plus two (2) 2 story duplex townhomes on the R- 14 zoned parcel. The existing homes and one outbuilding are proposed to be demolished. Vehicular access to the site is proposed via a private shared access driveway. The topography within the site includes regulated slopes from north to south (about 30 feet of elevation change). The proposed buildable areas on each R-14 zoned lot would range between 1,555 square feet and 2,022 square feet and between 2,722 square feet and 3,539 square feet for the R-8 zoned lots. Current Use: The properties contain two (2) existing single-family structures and a large outbuilding. All existing structures are proposed to be demolished. Comprehensive Plan/Zoning: Two (2) of the subject properties are located within the Residential Medium Density (RMD) land use designation and the R-8 zoning classification. The Residential Medium Density Land Use designation is intended to create opportunities for new Young Preliminary Plat, PRE22-000079 Page 2 of 10 April 7, 2022 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2022\PRE22-000079 single family residential neighborhoods and to facilitate high-quality infill development that promotes reinvestment in existing single family neighborhoods. The density range allowed in the R-8 zone is a minimum of 4.0 to a maximum of 8.0 dwelling units per one net acre. Detached single family residential dwelling units are a permitted uses within the R-8 zoning designation. The property located furthest east is located within the Residential High Density (RHD) land use designation and Residential-14 (R-14) zoning classification. The purpose of the Residential-14 Zone (R-14) is to encourage development, and redevelopment, of residential neighborhoods that provide a mix of detached and attached dwelling structures organized and designed to combine characteristics of both typical single-family and small-scale multi-family developments. Structure size is intended to be limited in terms of bulk and scale so that the various unit types allowed in the zone are compatible with one another and can be integrated together into a quality neighborhood. Project features are encouraged, such as yards for private use, common open spaces, and landscaped areas that enhance a neighborhood and foster a sense of community. Detached and attached dwelling are a permitted uses in the R-14 designation, provided the proposal complies with the density range specified by the zone. Development Standards: The project would be subject to RMC 4-2-110A, “Development Standards for Residential Zoning Designations” effective at the time of complete application (noted as “R-8 or R-14 standards” herein). These standards are available on the City’s website. Density – The density range allowed in the R-8 zone is a minimum of 4.0 to a maximum of 8.0 dwelling units per one net acre. The minimum net density requirements in the R-14 zone is 7 dwelling units per acre. The maximum net density is 14 dwelling units per net acre. Density bonuses are possible for applicants requesting additional market-rate dwelling units in exchange for the construction of affordable dwelling units (see RMC 4-9-065 for additional information). The area of public streets and critical areas would be deducted from the gross site area to determine the “net” site area prior to calculating density. In addition, net density is calculated after the deduction of critical areas, wetlands, Class 1 to 4 streams, floodways, and public rights- of-way and legally recorded private access easements. Required critical area buffers, public and private alleys, unit lot drives, drives, joint use driveways (and the access easements upon them), and trails shall not be subtracted from gross acres for the purpose of net density calculations. Calculations for minimum or maximum density which result in a fraction that is one-half (0.50) or greater shall be rounded up to the nearest whole number. Those density calculations resulting in a fraction that is less than one-half (0.50) shall be rounded down to the nearest whole number. A review of the proposed site plan that was submitted with the pre-application packet had an approximate gross acreage around 60,917 square feet (1.4 acres). The gross area of the R-8 zoned parcels is 29,867 square feet (0.69 acres) and the gross area of the R-14 zoned parcel is 31,050 square feet (0.71 acres). The gross density of the R-8 zoned parcel was calculated to be 7.2 dwelling units per acre (5 units / 0.69 acres = 7.2 du/ac) and the gross density of the R-14 zoned parcel was calculated to be 14.1 dwelling units per acre (10 units / 0.71 acres = 14.1 du/ac). Densities of 7.2 and 14.1 du/ac would meet the density ranges allowed for the R-8 and R-14 zones without density bonus allowances applied. A Density Worksheet would be required at the time of formal land use application. The applicant would be required to demonstrate compliance with the net density requirements of each zone at the time of formal application. 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. As proposed, it is unclear whether all five lots Young Preliminary Plat, PRE22-000079 Page 3 of 10 April 7, 2022 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2022\PRE22-000079 would meet the requirements for the R-8 zone after the proposed access easement or minimum access standard is applied. It is the applicant’s responsibility to demonstrate compliance with the minimum lot size, width and depth criteria of the zone at the time of formal application. There is no minimum lot size required for attached dwellings within the R-14 zone. The requirements for lot width and depth are 30 feet for interior lots and 40 feet for corner lots and the minimum lot depth is 60 feet, respectively. There is no minimum lot size, lot width or lot depth requirements for individual unit lot subdivisions. The applicant is proposing a subdivision with townhouses and single-family lots with widths and depths of variable distances. The applicant would be required to demonstrate compliance with lot standards of the zones at the time of formal application. Setbacks – Setbacks are the minimum required distance between the building footprint and the property line and any private access easement. The required setbacks for the R-8 zone are: Front yard: 20 feet for the primary structure (except when all vehicle access is taken from an alley, then 15 feet); Rear yard: 25 feet; Side yards: 5 feet; and Secondary Front yard: 15 feet. Corner lots required to have a front yard and a secondary front yard are relieved of the requirement to have a rear yard; in place of a rear yard setback, the side yard setback of the zone shall apply. The required setbacks in the R-14 zone are 15 feet for the front yard (except when all vehicle access is taken from an alley, then 10 feet), 10 feet for the rear yards, secondary front yards (applies to corner lots) would be required to have a 15-foot setback, and side yards are required to have a 4-foot setback for unattached sides and zero feet for the attached side(s). Compliance with setbacks would be reviewed through subdivision application. Building Height and Impervious Surface Coverage – 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 in the R-8 zone 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 maximum wall plate height. Detached accessory structures must remain below a height of 12 feet. The total floor area of all accessory buildings shall not be greater than the floor area of the primary residential uses. Accessory structures are also included in building lot coverage calculations. The maximum building coverage in the R-14 zone is 65 percent. The maximum impervious surface coverage is 80 percent of total lot area. The maximum wall plate height in the R-14 zone is restricted to 24 feet, increase up to 32 feet is possible subject to administrative conditional use permit approval, and the buildings shall be not more than three stories. The building height and coverage requirements would be verified at the time of formal application. Maximum Number of Units per Building – In the R-14 zone, no more than six (6) units per building. Young Preliminary Plat, PRE22-000079 Page 4 of 10 April 7, 2022 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2022\PRE22-000079 Residential Design and Open Space Standards: All new residential dwelling units in the R-8 and R-14 zones would be subject to the Residential Design Standards outlined in RMC 4-2-115. For example, dwellings shall be arranged to ensure privacy so that side yards abut other side yards (or rights-of-way) and do not abut front or back yards. Lots accessed by easements or pipestems shall be prohibited. In the R-14 zone, an open space requirement for four (4) or more units would require 350 square feet of common open space for each unit. Open space shall be located in a highly visible area and be easily accessible to the neighborhood. Open space(s) shall be contiguous to the majority of the dwellings in the development and accessible to all dwellings. For sites larger than one acre in size, open space(s) shall be at least forty feet (40') in at least one dimension. For all sites, to allow for variation, open space(s) of less than the minimum dimension (thirty feet (30') or forty feet (40'), as applicable) are allowed; provided, that when all of a site’s open spaces are averaged, the applicable dimension requirement is met. Common open space areas shall have a maximum slope of five percent (5%). In the R-14 zone, standards for private yards require each ground-related dwelling to have a private yard that is at least two hundred fifty (250) square feet in size with no dimension less than eight feet (8') in width. See RMC 4-2-115 for additional information and standards. All site design, open space and residential design standards applicable to the R-8 and R-14 zones would be verified at the time of preliminary plat and site plan review. Refuse and Recycling Areas: Refuse and recycling areas need to meet the requirements of RMC 4-4-090, “Refuse and Recyclables Standards.” Single family and two (2) attached residences (duplexes) shall be exempt from refuse and recycling standards. For multi-family developments a minimum of one and one-half (1-1/2) square feet per dwelling unit in multi-family residences shall be provided for recyclables deposit areas, except where the development is participating in a City-sponsored program in which individual recycling bins are used for curbside collection. A minimum of three (3) square feet per dwelling unit shall be provided for refuse deposit areas. A total minimum area of eighty (80) square feet shall be provided for refuse and recyclables deposit areas. The proposed six (6) townhomes (3-plex or greater) would require a minimum of 80 square feet for refuse and recyclables deposit areas. Multi-family residences using thirty-five (35) gallon garbage carts or smaller, when allowed, must be provided either within the garage or outside. Storage within a garage must be appropriately sized to accommodate both vehicles and refuse and recycling carts. Storage space for carts must measure at least two feet by six feet (2’ x 6’) floor area and sixty inches (60”) high. This space must be identified on floor plans. Storage located outside must measure at least two feet by six feet (2’ x 6’) in size and be located on the same lot as the dwelling in a side or rear yard. Outdoor storage must be adequately screened from public view, made of wood, masonry, or ornamental metal. The submitted material does not show compliance with the refuse and recycling standards. Compliance with the refuse and recyclable standards for multi-family use must be demonstrated at the time of formal application. See RMC 4-4-090 for additional information and standards. Landscaping: Pervious areas, with the exception of critical areas, shall have landscape treatment. Landscaping may include hardscape such as decorative paving, rock outcroppings, fountains, plant containers, etc. 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. Street trees shall be planted in the center of the planting strip between the curb and the sidewalk at the following intervals; provided, that, where right-of-way is constrained, irregular intervals and slight Young Preliminary Plat, PRE22-000079 Page 5 of 10 April 7, 2022 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2022\PRE22-000079 increases or decreases may be permitted or required. Additionally, trees shall be planted in locations that meet required spacing distances from facilities located in the right-of-way including, but not limited to, underground utilities, street lights, utility poles, traffic signs, fire hydrants, and driveways; such spacing standards are identified in the City’s Approved Tree List. Generally, the following spacing is required: i) Small-sized maturing trees: thirty feet (30') on center; ii) Medium-sized maturing trees: forty feet (40') on center; and iii) Large-sized maturing trees: fifty feet (50') on center. 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. Storm drainage facilities are required to comply with the minimum 15-foot perimeter landscaping strip on the outside of the fence unless otherwise determined through the site plan review or subdivision review process. Please refer to landscape regulations RMC 4-4-070 for further general and specific landscape requirements. Utility boxes that are not located in alleyways or away from public gathering spaces shall be screened with landscaping or berms. Stormwater Facility Perimeter Landscaping - A landscaping strip with a minimum fifteen feet (15') of width shall be located on the outside of the perimeter fence, unless otherwise determined through the site plan review or subdivision review process. A conceptual landscape plan prepared by a qualified professional shall be submitted at the time of formal land use application. Significant Tree Retention: If significant trees (greater than 6-inch caliper or 8-caliper inches for alders and cottonwoods) are proposed to be removed, a tree inventory, tree retention plan, arborist report, and tree retention worksheet shall be provided with the formal land use application as defined in RMC 4-8-120. Currently, tree retention plan must show preservation of at least 30 percent (30%) of significant trees in the R-8 zone and at least 20 percent (20%) of significant trees in the R-14 and indicate how proposed building footprints would be sited to accommodate preservation of significant trees that would be retained (please note that tree regulations (D-197) are proposed to change this year that would require properties subject to active land development permits to retain a minimum of thirty percent (30%) of all significant trees on site). Tree retention standards shall be applied to the developable area of a property (i.e., land within critical areas and their buffers, public rights-of-way, private PUD streets, shared driveways, and public trails shall be excluded). If the number to be retained includes a fraction of a tree, any amount equal to or greater than one-half (1/2) tree shall be rounded up. 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. Significant trees shall be retained in the following priority order: o 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. o Priority Two: Healthy tree groupings whose associated undergrowth can be preserved; other significant native evergreen or deciduous trees; and other significant non-native trees. Young Preliminary Plat, PRE22-000079 Page 6 of 10 April 7, 2022 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2022\PRE22-000079 o 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. 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. An inventory, retention plan, and arborist report would be required with the application if significant trees are to be removed. Fences/Retaining 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 and grading plan with top of wall and bottom of wall elevations. A fence and/or wall detail should also be included on the plan. A retaining wall that is 4 feet (4’) or taller, as measured by the vertical distance from the bottom of the footing to the finish grade at the top of the wall requires a building permit. The maximum height of any fence or retaining wall is 72-inches subject to further height limitations in setbacks and clear vision areas noted in RMC 4-4-040D. A fence shall not be constructed on top of a retaining wall unless the total combined height of the retaining wall and the fence does not exceed the allowed height of a standalone fence. For more information about fences and retaining walls refer to RMC 4-4-040. Hillside subdivisions: A subdivision in which the average slope is twenty percent (20%) or in which any street in the subdivision has grades greater than fifteen percent (15%) at any point. The subject development may be considered to be a hillside subdivision. The following additional standards shall apply to hillside subdivisions (RMC 4-7-220): 1. Application Information: Information concerning the soils, geology, drainage patterns, and vegetation shall be presented in order to evaluate the drainage, erosion control and slope stability for site development of the proposed plat. The applicant must demonstrate that the development of the hillside subdivision will not result in soil erosion and sedimentation, landslide, slippage, excess surface water runoff, increased costs of building and maintaining roads and public facilities and increased need for emergency relief and rescue operations. 2. Grading: Detailed plans for any proposed cut and fill operations shall be submitted. These plans shall include the angle of slope, contours, compaction, and retaining walls. Plans shall be consistent with requirements in RMC 4-4-060, Grading, Excavation and Mining Regulations. 3. Tracts: Areas of the subdivision deemed to be critical areas due to designation as protected slopes shall be located within a tract or tracts. 4. Streets: a. Streets may only have a grade exceeding fifteen percent (15%) if approved by the Department and the Fire Department. b. Street widths may be less than those required in the street standards for streets with grades steeper than fifteen percent (15%) if parking prohibition on one or both sides of the street is approved by the Administrator. Young Preliminary Plat, PRE22-000079 Page 7 of 10 April 7, 2022 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2022\PRE22-000079 5. Lots: Lots may be required to be larger than minimum lot sizes required by the Zoning Code. Generally, lots in steeper areas of the subdivision should be larger than those in less steep areas of the subdivision. 6. Erosion Control Requirements: Any clearing or grading shall be accompanied by erosion control measures as deemed necessary by the Department. Parking: Detached dwellings and townhouses require a minimum of two (2) parking spaces per dwelling unit; however, one (1) parking space per dwelling unit may be permitted for one (1) bedroom or less attached dwelling units. Tandem parking is allowed. Parking spaces within the garages shall be a minimum of 9’x20’. Bicycle parking is required for developments that exceed five (5) residential units. The proposal would be required to provide one-half (0.5) bicycle parking space per attached dwelling unit and ten percent (10%) of the number of required off- street vehicle parking spaces for detached dwellings. The bicycle parking provided for the residents shall provide for secure extended use and shall protect the entire bicycle and its components and accessories from theft and weather. Acceptable examples include bike lockers, bike check-in systems, in-building parking, and limited access fenced areas with weather protection. Spaces within the dwelling units or on balconies do not count toward the bicycle parking requirement. Please review RMC 4-4-080.F.10 and RMC 4-4-080.F.11 for further general and specific bicycle parking requirements. Access/Driveways: Access to the lots was proposed via a private shared access driveway and garages are proposed to be accessed via a short alley, such that all the single family detached homes and townhouses would be alley loaded. The maximum driveway slopes cannot exceed 15%. If the grade exceeds 15%, a variance is required. Driveways exceeding 8% shall provide slotted drains at the lower end with positive drainage discharge to restrict runoff from entering the residences or crossing any public sidewalks. A private shared access driveway would not comply with minimum levels of street improvements and design based on the proposed development (see Transportation Review Comments for more information). The location of the alley access and alley access points would be subject to approval of the Department of Community and Economic Development. Street Pattern: A grid street pattern shall be used to connect existing and new development and shall be the predominant street pattern. In addition, alley access is the preferred street pattern except for properties in the Residential Low Density land use designation. New residential development in areas without existing alleys shall utilize alley access for interior lots. Compliance with street requirements and minimum standards shall be demonstrated at the time of formal land use application. Critical Areas: According to COR Maps, the project site contains regulated slopes (>15% & <=40%). Geotechnical studies are required for development proposed on sites with any of the following geologically hazardous areas: a. Sensitive and protected slopes. b. Medium, high, or very high landslide hazards. c. High erosion hazards. d. High seismic hazards. e. Medium or high coal mine hazards. The required studies shall demonstrate the following review criteria can be met: Young Preliminary Plat, PRE22-000079 Page 8 of 10 April 7, 2022 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2022\PRE22-000079 a. The proposal will not increase the threat of the geological hazard to adjacent or abutting properties beyond pre-development conditions; and b. The proposal will not adversely impact other critical areas; and c. The development can be safely accommodated on the site. Studies submitted and reviewed are valid for five (5) years from the date of study completion unless the Administrator determines that conditions have changed significantly. A geotechnical engineering report would be required with the formal application materials. It is the applicant’s responsibility to determine whether any other critical areas are present on the site prior to formal land use application. Environmental Review: The proposed project would be subject to Washington State Environmental Policy Act (SEPA) due to the number of lots proposed. Therefore, an environmental checklist is a submittal requirement. An environmental determination will be made by the Renton Environmental Review Committee. Site Plan Approval: Per RMC 4-9-200, site plan review is required for any development in the R- 14 zone. The purpose of the site plan review process is to analyze the detailed arrangement of project elements to mitigate negative impacts where necessary to ensure project compatibility with the physical characteristics of a site and with the surrounding area. Site plan review ensures quality development consistent with City goals and policies. Site plan review analyzes elements including, but not limited to, site layout, building orientation and design, pedestrian and vehicular environment, landscaping, natural features of the site, screening and buffering, parking and loading facilities, and illumination to ensure compatibility with potential future development. Decisional criteria for site plan approval are itemized in RMC 4-9-200.E.3. Permit Requirements: The proposed subdivision of land into 15 or more individual lots showing the general layout of streets and alleys, lots, blocks, and other elements of a subdivision would require Preliminary Plat Review, Environmental (SEPA) Review, Site Plan Review, and a Conditional Use Permit (for building height increases in the R-14 zone, if necessary). All land use permits would be processed within an estimated time frame of 12 weeks. After the required notification period, the Environmental Review Committee would issue a Threshold Determination for the project. When the required two-week appeal period is completed, the project would go before the Hearing Examiner. Once the Hearing Examiner issues a decision, a two-week appeal period will commence. The 2022 Preliminary Plat Review, Site Plan Review and Conditional Use Permit application fees are $10,830, $3,800, and $3,300 respectively. The 2022 application fee for SEPA Review (Environmental Checklist) is $1,600. Any modification requests to code standards are $260 per modification. There is an additional 5% technology fee at the time of land use application. All fees are subject to change prior to submittal. Detailed information regarding the land use application submittal can be found on the Preliminary Plat submittal checklist and Site Plan submittal checklist. Other informational applications and handouts can be found on the City’s Digital Records Library. The city requires electronic plan submittal for all applications. Please refer to the City’s Electronic File Standards. In addition to the required land use permits, separate construction and building permits would be required. Public Information Sign: Public Information Signs are required for all Type II and Type III Land Use Permits as classified by RMC 4-8-080. Public Information Signs are intended to inform the Young Preliminary Plat, PRE22-000079 Page 9 of 10 April 7, 2022 CityofRenton\Department Folders\Community and Economic Development (CED)\Current Planning\Pre- Applications\2022\PRE22-000079 public of potential land development, specific permits/actions being considered by the City, and to facilitate timely and effective public participation in the review process. The applicant must follow the specifications provided in the public information sign handout. The applicant is solely responsible for the construction, installation, maintenance, removal, and any costs associated with the sign. Public Meeting: Please note a neighborhood meeting, according to RMC 4-8-090, is required for: a. Preliminary plat applications; b. Planned urban development applications; and c. Projects estimated by the City to have a monetary value equal to or greater than ten million dollars ($10,000,000), unless waived by the Administrator. The intent of this meeting is to facilitate an informal discussion between the project developer and the neighbors regarding the project. The neighborhood meeting occurs after a pre- application meeting and before submittal of applicable permit applications. The public meeting shall be held within Renton city limits, at a location no further than two (2) miles from the project site. Public Outreach Sign: Planned urban development projects require the applicant to install a public outreach sign. Public outreach signs are intended to supplement information provided by public information signs by allowing an applicant to develop a personalized promotional message for the proposed development. The sign is also intended to provide the public with a better sense of proposed development by displaying a colored rendering of the project and other required or discretionary information that lends greater understanding of the project. Impact Fees: In addition to the applicable building and construction fees, impact fees would be required. Fees change periodically and the fees in effect at the time of building permit issuance would apply. For informational purposes, the 2022 impact fees are as follows: A Fire impact fee based on the rate established by the Renton Fire Authority would be assessed based on the use. For example, fire impact fee is assessed at $964.53 per new multi-family dwelling unit or $829.77 per new single family dwelling; A transportation impact fee for new multi-family dwelling unit is assessed at $6,717.10 per new unit or $10,861.69 for a new single family dwelling; Renton School District Impact Fee assessed at $4,737 per new multi-family dwelling unit or $2,659 per new single family dwelling (+5% administrative fee) unless an exemption can be made under RMC 4-1-190.I.1.a; and Parks Impact Fee currently assessed at $1,977.62 (5 or more units) per new multi-family dwelling unit or $2,914.99 per new single family dwelling.
