PROJECT NAME: Carpenter Short Plat
PROJECT NUMBER: LUA17-000659, U16-004636
PROJECT MANAGER: Ian Fitz-James, Civil Engineer III
APPLICANT: Chad Allen
Encompass Engineering and Surveying

ZONING CLASSIFICATION: R8-Residential (8 DU/AC)
PROJECT LOCATION: Parcel No. 334570-0235
SUMMARY OF REQUEST:
Pursuant to RMC 4-9-250D the applicant is requesting an Administrative Modification from
RMC 4-6-060 - Street Standards to modify Lincoln Avenue NE from a residential street section
to a modified residential street section reducing the landscape strip from 8-feet to 5-feet and
shifting the roadway centerline to the west of the right of way centerline to account for the
steep slopes and existing driveway on the east side of the roadway.
BACKGROUND:
Lincoln Avenue NE is classified as a residential street with an existing right of way width of 60’
per the King County Assessor’s Map. The existing pavement width is approximately 16-feet
wide and consists of two travel lanes and gravel shoulders.
Per RMC 4-6-060, a residential street with two lanes requires a minimum right of way width of
53’. A paved roadway width of 26-feet consisting of 2 – 10 foot travel lanes and a 6 foot
parking lane is required. A 0.5-foot curb, 8-foot planter, and 5-foot sidewalk are required along
each side of the pavement. To meet the City’s complete street standards, construction of
approximately 4 feet of additional pavement (to meet the minimum 20-foot pavement width
required for half street improvements), a 0.5-foot curb, an 8-foot planter, and a 5-foot sidewalk
would be required.
City staff has determined that a modified residential street standard better suits this portion of
Lincoln Avenue NE due to the steep slopes and existing driveway on the east side of th e right of
way which reduces the usable right of way available for the roadway improvements. The half

ANALYSIS OF REQUEST:
The Section 4-6-060Q.1 allows the Administrator to grant modifications provided the
modifications meet the following criteria (pursuant to RMC 4-9-250D.2):
Compliance Street Modification Criteria and Analysis
a. Substantially implements the policy direction of the policies and objectives of the
Comprehensive Plan Land Use Element and the Community Design Element and the
proposed modification is the minimum adjustment necessary to implement these
policies and objectives.
Staff Comment:
The Comprehensive Plan Land Use Element has applicable policies listed under a
separate section labeled Promoting a Safe, Healthy, and Attractive Community. These
policies address walkable neighborhoods, safety and shared uses. These policies address
walkable neighborhoods, safety and shared uses. The intent of the policies is to
promote new development with walkable places that support grid and flexible grid
street and pathway patterns, and are visually attractive, safe, and healthy
environments. The requested street modification is consistent with these policy
guidelines.
b. Will meet the objectives and safety, function, appearance, environmental protection
and maintainability intended by the Code requirements, based upon sound
engineering judgment.
Staff Comment:
The City’s Community and Economic Development have reviewed Lincoln Avenue NE
along with the steep slopes and existing driveway on the east side of the roadway and
have determined that a modified residential street section is more suitable for this
location on Lincoln Avenue NE. This determination was based on the fact that the
roadway is directly adjacent to a steep slope and there is insufficient space between the
proposed roadway and the existing slope and driveway in order to construct the
roadway without dramatically changing the roadway profile.
The modified street improvements will meet the objectives of a safe walkable
environment consistent with the surrounding neighborhood.
