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 for purchase for $100.00 plus tax, from the Finance Division on the first floor of City Hall or online at www.rentonwa.gov Project Proposal: The subject property is located at 17019 108th Avenue SE. The project site consists of one parcel which is 20,000 square feet (0.35 acre) in area and zoned Residential-14 dwelling units per acre (R-14). The applicant proposes to subdivide the site into 5 lots and has indicated building footprints for the future development of five single-family residences. It appears that the existing house on proposed Lot 1 would be removed. The lots vary in size from 3,068 square feet to 4,125 square feet. Access to all five proposed lots would be via a 20-foot access easement from a curb cut on 108th Avenue SE. Current Use: The parcel is developed with a 500 square foot single-family residence to be removed. Zoning / Density: The property is located within the Residential -14 dwelling units per acre (R-14) zoning designation. Detached and attached residential development is permitted within the R-14 designation, provided the proposal complies with the density range specified by the zone (minimum 10 dwelling units per acres to a maximum of 14 dwelling units per acre). However, up to 18 dwelling units per net acre (du/ac) are allowed as a bonus, subject to Density Bonus Review (RMC 4-9-065). The area of public Teng Short Plat, PRE12-031 Page 2 of 9 April 26, 2012 h:\ced\planning\current planning\preapps\12-031.jerry\12-031 (r-14 teng shpl).doc and private streets and critical areas would be deducted from the gross site area to determine the “net” site area prior to calculating density. The City would require 8-feet of additional right-of-way dedication along 108th Avenue SE as well as requiring a 26- foot wide private access road within the short plat. Based on right-of-way dedication required and internal access width requirements, the area to be deducted from the gross area of the project site is approximately 6,996 square feet. This would result in a net density of 16.67 du/acre, which exceeds the maximum density without Bonus Density Review. Please note that a reduction in the number of lots may satisfy the maximum density requirement. Density Bonus Review: The bonus provisions are intended to allow greater flexibility in the implementation of the purpose of the R-14 designation. A copy of the density bonus criteria has been attached to this memo. In order to qualify for the bonus density, the project must demonstrate that the same or better results will occur as a result of creative design solutions that would occur with uses developed under standard criteria at lower density. The applicant has not proposed to utilize the density bonus provisions in the project narrative. Development Standards: The submitted site plan indicates building envelopes for a single-family residence on each of the proposed five lots. Future development would be subject to RMC 4-2-110A, “Development Standards for Residential Zoning Designations” effective at the time of building permit application. These standards are as follows: Type of Standard R-14 Minimum Standard Lot Size None Lot Width and Depth Not Applicable Min Front Yard 10 ft., except garage/carport setback which shall be 15 ft. Max Front Yard None Side Yard Detached Units: 4 ft. Attached Units: 4 ft. for the unattached side(s) of the structure. 0 ft. for the attached side(s).23. Rear Yard 12 ft. Side Yard Along-A-Street 10 ft. except garage/carport setbacks which shall be 15 ft. Building Coverage Ratio n/a Impervious Surface Area 85% Maximum Gross Floor Area None Height 30 ft Units per Lot Detached single family dwellings: 1 dwelling unit with 1 accessory dwelling unit Teng Short Plat, PRE12-031 Page 3 of 9 April 26, 2012 h:\ced\planning\current planning\preapps\12-031.jerry\12-031 (r-14 teng shpl).doc Attached dwellings: None Units per Building No more than six (6) dwelling units per building Landscaping Tree Retention 10 % of significant trees Setbacks – Because proposed the front yards of proposed Lots 2 through 5 should be oriented to the south, the building envelope shown for proposed Lot 2 would not meet the front and rear yard setback requirements. Compliance with setback standards would be reviewed at the time of building permit application. Impervious Surface Area – There is not enough information provided with the application for staff to determine compliance with this standard. A lot coverage analysis meeting the requirements in RMC 4-8-120D.12, shall be submitted at the time of formal landuse application. Height – There is not enough information provided with the application for staff to determine compliance with the maximum height standards. Access/Parking – The following ratios would be applicable to the site: Use # of Units Ratio Required Spaces Single Family Residential 5 A minimum of 2 per dwelling unit, however, 1 per dwelling unit may be permitted for 1 bedroom or less dwelling units 5 to 10 Based on these parking requirements, minimum 5 to 10 parking spaces would be required in order to meet Code requirements. Pedestrian Access Sidewalks shall be provided throughout the neighborhood. The sidewalk may disconnect from the road, provided it continues in a logical route throughout the development. Front yards shall have entry walks that are a minimum width of 3 feet and a maximum width of 4 feet. Pathways shall be used to connect common parks, green areas, and pocket parks to residential access streets, limited residential access streets, or other pedestrian connections. They may be used to provide access to homes and common open space. They shall be a minimum of 3 feet in width and made of paved asphalt, concrete, or porous material such as: porous paving stones, crushed gravel with soil stabilizers, or paving blocks with planted joints. Sidewalks or pathways for parks and green spaces shall be located at the edge of the common space to allow a larger usable green and easy access to homes. A pedestrian circulation plan shall be provided with the formal land use application.

Fences – If the applicant intends to install any fences as part of this project, the location must be designated on the landscape plan. A fence detail should also be included on the plan as well. Critical Areas: It appears that a wetland may be located on the project site. The applicant would be required to provide Wetland Reconnaissance Report, prepared by a qualified biologist with the formal land use application. Please note that wetland areas, if found to exist on the project site, would be deducted from the gross area to determine net density. Environmental Review The project may require Environmental (SEPA) Review if the Wetland Reconnaissance Report indicates that wetlands exist on the project site. Permit Requirements: An Administrative Short Plat approval is required; the fee for a Short Plat is $1,442.00 ($1,400.00 plus 3% Technology Surcharge Fee). An Environmental (SEPA) Review may also be required if wetlands are found to be present on the project site; the fee for SEPA review is $1,030.00 ($1,000.00 plus 3% Technology Surcharge Fee). The Short Plat and Environmental Review (if required) would be processed concurrently and would take approximately 6 to 8 weeks to complete. Upon receipt of preliminary approval, the applicant must complete any required improvements, such as sidewalks, fire hydrants and grading. A separate construction permit is required for these improvements. The applicant must also satisfy any conditions of the preliminary approval before the plat can be recorded. A separate no fee submittal is required for the final short plat. The newly created lots may be sold only after the plat has been recorded. The applicant can submit plans for building permit review for new construction before the plat is recorded, however, the City can issue building permits only when the final plat has been recorded. Detailed information regarding the land use application submittal is provided in the attached handouts. Teng Short Plat, PRE12-031 Page 9 of 9 April 26, 2012 h:\ced\planning\current planning\preapps\12-031.jerry\12-031 (r-14 teng shpl).doc In addition to the required land use permits, separate construction and building permits would be required. The review of these permits may occur concurrently with the review of the land use permits, but cannot be issued prior to the completion of any appeal periods. Impact/Mitigation Fees: In addition to the applicable building and construction fees, the following mitigation fees would be required prior to the recording of the short plat. Impact fees, which would replace mitigation fees, may be adopted prior to building permit approval for which an applicant may vest to impact/mitigation fees. Those fees have yet to be determined. Currently fees are the following: A Parks Mitigation Fee based on $530.76 per new single family lot payable prior to recording; A Transportation Mitigation Fee based on $75.00 per each new average daily trip attributable to the project payable prior to recording; A Fire Mitigation Fee based on $488.00 per new single-family lot payable prior to recording; and, A Renton School District Impact Fee based on $6,392.00 per each new single- family residence payable prior to issuance of building permits. A handout listing all of the City’s Development related fees in attached for your review. Expiration: Upon preliminary short plat approval, the preliminary short plat approval is valid for two years with a possible one-year extension. cc: Jennifer Henning
