FROM: Jill Ding, Senior Planner
SUBJECT: Thomas Residence –
3209 Mountain View Ave N, Renton, WA 98056
Parcel No. 3342103810
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, Development Engineering 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 is located at 3209 Mountain View Avenue N (Parcel
No. 3342103810). The proposed project site is currently developed with an existing single
family residence and is zoned Residential-8 (R-8). The applicant is proposing to construct
approximately 663 square feet of new upper level deck area, approximately 665 square feet
of new ground level deck area, and the reconstruction of an existing 162 square foot entry
structure to an existing 1,755 square foot single family resid ence. The project site is located
along Lake Washington and is subject to the requirements of the Shoreline Management Act
and Shoreline Master Program. Per RMC 4-3-090, the vegetation conservation buffer
required for lots with a depth of between 130 feet and 150 feet is twenty feet (20’) with a
fifteen-foot (15’) building setback from the edge of the buffer for a total setback of thirty-five
feet (35’). The existing single family residence is located approximately thirty-nine feet (39’)
from the ordinary high water mark (OHWM) of Lake Washington, which would comply with
the shoreline setback requirements. No changes in access are proposed. The project site is
located within the Shoreline Residential Designation of Lake Washington, Reach E. Sensitive
slopes and moderate and high landslide hazard areas are mapped on the project site.
Current Use: The site is currently developed with an existing single family residence,
proposed to remain.

1. Zoning/Density Requirements: The property is located within the Residential Medium
Density (RMD) land use designation. The subject property is zoned Residential -8 (R-8).
Detached single family dwelling units are an outright permitted use within the R -8 zone.
2. 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-6 standards” herein).
Building Standards – The Shoreline Residential Designation has a maximum building
coverage of twenty five percent (25%) for buildings landward of the vegetation
conservation buffer, and within 100 feet of the OHWM. In addition, the Shoreline
Residential Designation has a maximum impervious surface coverage of fifty percent
(50%) for the area landward of the vegetation conservation buffer and within 100 feet of
the OHWM. The maximum building height is restricted to 24-feet from grade plane to the
highest wall plate and 2 stories. Roofs with a pitch equal to or greater than 4:12 may
project an additional 6 vertical feet. The proposed addition would be required to
demonstrate compliance with these requirements at the time of formal land use and
building permit application.
Setbacks – Setbacks are the minimum required distance between the building footprint
and the property line and any private access easement. The required minimum setbacks
in the R-8 Zone are 20 feet in front, 25 feet in the rear and the side yard setback is 5 feet.
Per RMC 4-3-090, the vegetation conservation buffer required for lots with a depth of
between 130 feet and 150 feet is twenty feet (20’) with a fifteen-foot (15’) building setback
from the edge of the buffer for a total setback of t hirty-five feet (35’). The existing single
family residence is located approximately thirty-nine feet (39’) from the ordinary
high water mark (OHWM) of Lake Washington and is compliant with respect to the
shoreline setback requirements. The existing residence appears to project into the
required twenty-foot (20’) front yard setback along Mountain View Ave N. The
applicant would be required to demonstrate that the proposed addition s would
comply with the required setback requirements of the R-8 zone and shoreline
master program at the time of formal land use and building permit application.
3. Access/Parking: Each lot is required to accommodate off street parking for a minimum
of two vehicles. Driveways and curb cuts are subject to RMC 4 -4-080I. The applicant
would be required to demonstrate compliance with the parking requirements at the
time of formal land use and building permit application.
4. Driveways: The maximum driveway slope 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.
5. 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 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.
Please refer to RMC 4-4-130, Tree Retention and Land Clearing Regulations for further
general and specific tree retention and land clearing requirements.

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; significant trees over sixty feet (60') in height or
greater than eighteen inches (18") caliper; and trees that shelter interior trees or trees on
abutting properties from strong winds, which could otherwise allow such sheltered trees
to be blown down if removed.
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

The Administrator may require independent review of any land use application that
involves tree removal and land clearing at the City's discretion.
The Administrator may authorize the planting of replacement trees on the site if it can be
demonstrated to the Administrator's satisfaction that replacement requirements in RMC
4-4-130H1e can be met.
Tree retention standards shall be applied to the developable area, as defined in RMC
4-11-040, Definitions D, of a property. A formal tree retention plan and tree retention
worksheet prepared by an arborist or landscape architect would be reviewed at the
time of the land use and building permit application.
6. Critical Areas: According to the City’s COR Mapping system, the site is mapped within a
high seismic hazard area and is located within the 200-foot shoreline jurisdiction of Lake
Washington. The site is mapped within the Shoreline Residential Designation of Lake
Washington Reach E. A lake study may be required to be submitted with the project
application.
Sensitive slopes and moderate and high landslide hazard areas are mapped on the
project site. A geotechnical report may be required to be submitted at the time of
building permit review.
7. Shoreline Master Program: The project site is located within the Shoreline Residential
Designation of Lake Washington Reach E. Any proposed development of the project site
would be subject to the City’s adopted Shoreline Master Program (RMC 4 -3-090). The
development of a single family residence for the use and enjoyment of the property
owner would be exempt from a Shoreline Substantial Development Permit.
8. Environmental Review: The proposal would be exempt from Environmental (SEPA)
Review, in accordance with WAC 197-11-800.
9. Permit Requirements: A Shoreline Exemption application would be reviewed within an
estimated time frame of 3-4 weeks. Shoreline Exemptions are not subject to any
application fees. All fees are subject to change. Detailed information regarding the land
use application submittal can be found on the City’s Permit Center website
(www.Rentonwa.gov). The City now requires electronic plan submittal for all
