DATE:August 15, 2012
TO:Pre-Application File No. 12-061
FROM:Rocale Timmons, Associate Planner
SUBJECT:Taylor Preliminary Plat (17709 116th Ave SE)
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 for purchase for $50.00 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 on the west side of 116th Ave SE south of SE
Petrovitsky Rd. The applicant is proposing a preliminary plat for a 21-lot subdivision of a 3.63-
acre site located within the R-8 zoning designation. The proposed lots are intended for the
eventual development of detached single-family homes. Access to the site would be gained
from 116th Ave SE via a new east/west public road (SE 177th Pl) connecting to the existing
portion of SE 177th Pl. The applicant has proposed two access tracts extending off of the
proposed road. The site does not contain any critical areas.
Current Use: The site is currently contains a single family residence proposed for demolition.
Zoning/Density Requirements: The subject property is located within the R-8 zoning
designation. The density range allowed in the R-8 zone is a minimum of 4.0 to a maximum of
8.0 dwelling units per acre (du/ac). 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. It appears the net density of the site would be approximately 7.00 du/ac which is
within the density range for the R-8 zoning classification.
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 is 4,500 square
feet for parcels greater than 1 acre in size and 5,000 square feet for lots 1 acre or less in size.
The total lot area of the subject site is more than 1 acre; therefore a minimum lot size of 4,500
square feet is applicable to the proposed project. A minimum lot width of 50 feet for interior
lots and 60 feet for corner lots, as well as a minimum lot depth of 65 feet, is also required. The
proposal appears to comply with the lot size, width and depth requirements of the zone.
Lot Arrangement - RMC 4-7-170 states that insofar as practical, side lot lines shall be at right
angles to street lines or radial to curved street lines. The proposed plat’s arrangement of lots
does not meet this requirement. The applicant is encouraged to redesign the plat or will be
required to reduce the number of lots in order to comply with this requirement.
Building Standards – R-8 zone allows a maximum building coverage of 35% of the lot area or
2,500 square feet, whichever is greater for lots over 5,000 square feet in size and a maximum
impervious surface 75%. Building height is restricted to 30 feet from existing grade. Detached
accessory structures must remain below a height of 15 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 proposal’s compliance with the building standards would be
verified at the time of building permit review for the new residences to be located on all lots.
Building Design Standards – All single family residences would be subject to the Residential
Design Standards outlined in RMC 4-2-115. The proposal’s compliance with the residential
design standards would be verified at the time of building permit review for the new
residences to be located on all lots. Please take not of the following standards
One of the following is required:
Lot width variation of 10 feet (10') minimum of one per four (4) abutting street-fronting
lots, or
Minimum of four (4) lot sizes (minimum of four hundred (400) gross square feet size
difference) for at least every four (4) abutting street fronting lots, or
A front yard setback variation of at least five feet (5') minimum for at least every four (4)
abutting street fronting lots.
Setbacks – Setbacks are the minimum required distance between the building footprint and the
property line and any private access easement. The required setbacks in the R-8 zone are 15
feet in front for the primary structure and 20 feet in front for the attached garage, 20 feet in the
rear, 5 feet on interior side yards, and 15 feet on side yards along streets (including access
easements) for the primary structure and 20 feet on side yards along streets (including access
easements) for the attached garage. The setbacks for the new residences would be reviewed at
the time of building permit.
Access/Parking: Access to site is proposed off of 116th Ave SE via a new east/west public road
(SE 177th Pl) connecting to the existing portion of SE 177th Pl. The applicant has proposed two
access tracts extending off of the proposed road for access to Lots 16-20 (Tract A) and Lots 1-4
and 6 (Tract B). Private streets are allowed, per RMC 4-6-060J, for access to 6 or fewer lots,
provided at least 2 of the 6 lots abut a public right-of-way. Tract A would not meet this
requirement and the plat would be required to be revised in order to comply with this private
street standard.

RMC 4-7-150 states alley access is the preferred street pattern. Prior to approval of a plat
without alley access, the Reviewing Official shall evaluate an alley layout and determine that
the use of alley(s) is not feasible.
Per RMC 4-7-170F all pipe-stems are required to be no less than 20 feet in width. Lot 6 would
be required to revised to comply with this requirement.
Each lot is required to accommodate off street parking for a minimum of two vehicles.
Driveways: The maximum driveway slopes cannot exceed 15%, provided that driveways
exceeding 8% are to provide slotted drains at the lower end of the driveway. If the grade
exceeds 15%, a variance is required.
Landscaping – Except for critical areas, all portions of the development area not covered by
structures, required parking, access, circulation or service areas, must be landscaped with
native, drought-resistant vegetative cover. The development standards require that all pervious
areas within the property boundaries be landscaped. The minimum on-site landscape width
required along street frontages is 10 feet.
Please refer to landscape regulations (RMC 4-4-070) for further general and specific landscape
requirements (enclosed). The conceptual landscape plan submitted with the pre-application
materials is required to be revised to include a 10-foot wide on-site landscape strip on each
lot.
Significant Tree Retention: If significant trees (greater than 6-inch caliper) are proposed to be
removed a tree inventory and a tree retention plan along with a tree retention worksheet shall
be provided with the formal land use application. The tree retention plan must show
preservation of at least 30 percent of significant trees, and indicate how proposed building
footprints would be sited to accommodate preservation of significant trees that would be
retained. If the trees cannot be retained, they may be replaced with minimum 2 inch caliper
trees at a ratio of six to one. The applicant will be required to retain stands of trees on the
perimeter of lots.
Critical Areas: The project site appears to contain a Class 4 stream and a Category 2 wetland.
The applicant is proposing wetland buffer averaging in order to accommodate the proposed
drainage tract. A conceptual mitigation would be required to be submitted, as part of the
formal land use process, demonstrating mitigation sequencing and showing a net increase in
the function and value of the wetland system. Secondary review of the wetland report and/or
mitigation plan may be required at the applicant’s expense. All critical areas and buffers are
required to be placed in a Native Growth Protection Easement (NGPE).
Environmental Review: Environmental (SEPA) Review is required for projects nine lots or
greater, or on sites that contain critical areas. Therefore SEPA would be required for the
proposed subdivision.
Permit Requirements:
The proposed subdivision would require Preliminary Plat Approval and Environmental (SEPA)
Review. All land use permits would be processed within an estimated time frame of 12 weeks.
The Preliminary Plat Review application fee is $4,000. The application fee for SEPA Review
(Environmental Checklist) is $1,000. A 3% technology fee would also be assessed at the time of
land use application. Detailed information regarding the land use application submittal is
provided in the attached handouts.

Fees: In addition to the applicable building and construction fees, the following mitigation fees
would be required prior to the recording of the plat. Impact fees, which would replace
mitigation fees, may be adopted prior to construction. Those fees are to be determined. The
following are current fees:
A Fire Mitigation fee of $488.00 per new single family residence.
A Transportation Mitigation Fee based on $75.00 per each new average
daily trip attributable to the project; and
A Parks Mitigation Fee based on $530.76 per new single family residence.
A School District Impact Fee based on $6,392 per new single family
residence.
A handout listing all of the City’s Development related fees in attached for your review.
Expiration: The preliminary plat approval is valid for seven years with a possible one-year
extension.
