DATE:July 5, 2012
TO:Pre-Application File No. 12-050
FROM:Vanessa Dolbee, Senior Planner
SUBJECT:Saddlebrook Preliminary Plat – 13426 156th 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 at 13426 and 13430 156th Avenue SE and is
comprised of two parcels. The project site totals 4.36 acres in area, and is zoned Residential-4
dwelling units per net acre (R-4). The proposal is to subdivide the existing parcel into 14 lots for
the future construction of single family residences. Access to the site is proposed via a new
public road off of 158th Avenue SE.
Current Use: The property is currently developed with a single family home, garage and horse
pen.
Zoning/Density Requirements: The subject property is located within the R-4 zoning
designation. The maximum density allowed in the R-4 zone is 4.0 units per net 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. Using the information
provided with the application, 0.681 acres of the site would be dedicated as a public road
resulting in 3.676 acres of net developable area. The division of 3.676 acres into 14 lots results
in a net density of 3.81 du/ac (14 lots /3.676 acres = 3.81 du/ac), which is within the density
range permitted in the R-4 zone. The project would need to meet density requirements using
“net” square footage.
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-4 standards” herein).

Minimum Lot Size, Width and Depth – The minimum lot size permitted in the R-4 is 8,000 square
feet. A minimum lot width of 70 feet for interior lots and 80 feet for corner lots, as well as a
minimum lot depth of 80 feet, is also required. Based on the provided information, it appears
the proposed lots would comply with minimum lot size, width and depth requirements.
Building Standards – R-4 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. 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.
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-4 zone are 30
feet in front for the primary structure. However, the front yard setback of the primary structure
may be reduced to 20 feet if all parking is provided in the rear yard of the lot with access from a
public right-of-way or alley. The rear yard setback is 25 feet. Interior side yard setbacks are 5
feet. Side yards along-a-street (including access easements) are 15 feet for the primary
structure and 20 feet on side yards along streets (including access easements) for the attached
garage gaining access from the side street. The setbacks for the new residences would be
reviewed at the time of building permit.
Access/Parking: Each lot is required to accommodate off street parking for a minimum of two
vehicles. Access to the site is proposed via a new public road extended from 158th Avenue SE.
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. 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').
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). A conceptual landscape plan shall be submitted at the time of
Preliminary Plat application.
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.
Critical Areas: The subject site does not appear to contain any critical areas.

Environmental Review: The proposed project would be subject to Washington State
Environmental Policy Act (SEPA) review due to the number of proposed units. Therefore, an
environmental checklist is a submittal requirement. An environmental determination will be
made by the Renton Environmental Review Committee. This determination is subject to appeal
by either the project proponent, by a citizen of the community, or another entity having
standing for an appeal.
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 10-12
weeks. The Preliminary Plat Review application fee is $4,000. The application fee for SEPA
Review (Environmental Checklist) is $1,000. There is a technology fee, of 3 %, based on the total
land use application fees for the project. 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 issuance of building permits. 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 $6,310 per new single family
residence.
A handout listing all of the City’s Development related fees in attached for your review.
Expiration: Upon preliminary plat approval, the preliminary plat approval is valid for five years
with a possible one-year extension.

NOTE: The applicant is cautioned that information contained in this summary is preliminary and non-
binding and may be subject to modification and/or concurrence by official city decision-makers. 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.
I have completed a preliminary review for the above-referenced 14-lot plat proposal, located east of and
adjacent to Vesta Ave NE (156th Ave SE), west of and adjacent to Yakima Ave NE (158th Ave SE), and on
the NE 1st St grid line in Sect. 14, Twp 23N Rng 5 E. The following comments are based on the pre-
application submittal made to the City of Renton by the applicant.
WATER:
This site is not located in the City of Renton water service boundary. It is located in the Water
District 90 area and a Certificate of Water Availability is required and shall be submitted prior to
formal application.
This site is not located in the Aquifer Protection Zone.
The project will need to provide domestic and fire service to serve the proposed development.
Per the City Fire Marshal, the preliminary fire flow requirement for a single family home 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. Lateral spacing of fire hydrants is predicated on hydrants
being located at street intersections.
All fire hydrants need to be brought up to current code if not existing.
SANITARY SEWER:
This site is located in the City of Renton sanitary sewer service boundary.
There is an existing 8” sewer main in Vesta Ave NE. See City of Renton sanitary sewer drawing #S-
3338 for details.

There is an existing 8” sewer main in Yakima Ave NE. See City of Renton sanitary sewer drawing #S-
3148 for details.
Project plans need to show how sanitary sewer will be provided to each unit with an individual
sewer service line. Per code, the project needs to extend sanitary sewer along the full frontage of
the parcel being developed.
This proposal is located in the Central Plateau Interceptor Area Special Assessment District (SAD
0034). These fees are $351.95, plus interest, per unit and shall be paid at the time a construction
permit is issued and prior to recording the plat.
Sanitary Sewer system development (SDC) fees are based on the size of the domestic water meters.
These fees are collected at the time a construction permit is issued.
STREET IMPROVEMENTS:
The project shall be required to install curb, gutter, sidewalk, and street lighting on the full frontages
of the parcel being developed.
The street improvements on Vesta Ave NE shall be a 5-foot bike lane, curb 17 feet from centerline of
right-of-way, followed by an 8-foot planter strip, and a 5-foot sidewalk. Additional right-of-way not
required for this.
The street improvements on Yakima Ave NE shall be a 32-foot pavement to allow for parking on
both sides, curb 16 feet from centerline of right-of-way, followed by an 8-foot planter strip and a 5-
foot sidewalk. Additional right-of-way not required for this.
The new internal street shall be extended the full width of the development connecting to both
Vesta and Yakima Ave NE. The street shall have a 26-foot pavement section, allowing parking on
one side, an 8-foot planter, and 5-foot sidewalk in a 52’ dedicated right-of-way.
Street lighting shall be per current City of Renton standards and specifications. Residential style LED
Luminaires spaced approximately 110’ is required internally to the proposed plat and on 158th;
Cobra type or other arterial luminaires as approved by the City of Renton will be required on Vesta.
See City of Renton details.
Per City of Renton code, all lot corners at intersections of dedicated public rights-of-way shall have a
minimum radius of fifteen feet (15’).
All new electrical, phone, and cable services and lines must be undergrounded. The construction of
these franchise utilities must be inspected and approved by a City of Renton public works inspector
prior to recording the plat.
Traffic mitigation fees apply; these fees are approximately $750 per lot at this time.
A limited traffic study evaluating the 156th access intersection turning movements and sight distance
is required.
STORM DRAINAGE:
There are existing storm drainage facilities in both Vesta and Yakima Ave NE. See drawing #S-4031.
A drainage control plan designed per the King County Surface Water Manual 2009 is required.
The conceptual storm drainage plan needs to address how the roof runoff from the new lots will be
handled. This site is located in the Flow Control Duration Standard Forested Conditions.
Surface Water SDC fees are $1,012 per lot if individually owned or $0.405 per square foot of new
impervious area if not individually owned lots. These fees are collected at the time a construction
permit is issued.
