I-405 Renton to Bellevue – STREET MODIFICATION
Admin. Modification Request Report & Decision
LUA18-000669
EXISTING CONDITIONS:
NE 44th St / Lake Washington Blvd N Street Conditions (West of I-405) at Location of Proposed Modified
Street Standard
Within the project area, NE 44th St / Lake Washington Blvd N, west of the I-405 NE 44th Interchange, outside
of WSDOT Limited Access, consists of a two-lane roadway. An existing eastbound left turn pocket is present
for eastbound to northbound left turns to Seahawks Way.
Currently no contiguous accessible pedestrian pathways exist along this stretch of roadway. There is a 250-
foot long segment of 12-foot wide sidewalk located on the east side of Lake Washington Blvd N from the
north side of May Creek Bridge to a point of termination approximately 200 feet south of the intersection
with N 43rd St. Striped roadway shoulders are marked for bike lane use south of N 43rd St. Varying width
roadway shoulders are available for pedestrian use but are not accessible from the curbed facilities, see
Exhibit A1.
N 43rd St and Seahawks Way Street Conditions:
N 43rd St consists of a two-lane roadway with existing 5-foot wide sidewalk on the south side of the street.
No pedestrian walkway conditions exist on the north side of the street. A new trail marked crossing and
access to the Eastside Rail Corridor Trail was recently constructed at the prior-existing railroad crossing.
Seahawks Way consists of a two-lane roadway with paved shoulders. Rolled curbs with paved shoulders
exist at the intersection returns to NE 44th St. No separated pedestrian facilities exist present day. For
existing conditions within the NE 44th St vicinity west of I-405, see Exhibit A1.
NE 44th / 110th Ave SE St Street Conditions – East of I-405 (Outside of WSDOT Limited Access)
Within the project area, NE 44th St east of the I-405 NE 44th Interchange, outside of WSDOT Limited Access,
consists of a 5-lane roadway section with 2 traveled lanes in each direction plus a center two-way left turn
lane. The outside westbound traveled lane is dropped via right turn only lane and the outside eastbound
traveled lane is added at the NE 44th St intersection with Lake Washington Blvd NE. The outside westbound
traveled lane is added at the driveway access to apartment complex at 7920 110th Ave SE, and the outside
eastbound traveled lane is dropped via right turn only lane at the NE 44th St intersection with NE 43rd Pl /
Lincoln Ave NE. The paved westbound shoulder between driveway access to 7920 110th Ave SE and the NE
44th / 110th Ave SE intersection with NE 43rd Pl / Lincoln Ave NE is currently utilized for on-street parking.
There is a 5-foot wide sidewalk on the north side of the street and a 6-foot wide sidewalk on the south side
of the street. No roadway planters are present, but the remaining ROW beyond the back of sidewalk is
vegetated. No in street or separated bicycle facilities exist on NE 44th St within this segment of roadway. For
the existing conditions within the NE 44th vicinity east of I-405, see Exhibit B1.
Lake Washington Blvd NE Street Conditions
Within the project area Lake Washington Blvd NE, east of the I-405 NE 44th Interchange consists of a 2-lane
roadway with a paved shoulder on the west side and curb and gutter with 5-foot wide paved sidewalk
located on the east side of the street. A center turn lane is developed approximately 500 feet north of the
intersection with NE 44th St and extends through the limits of the project area. A contiguous pedestrian
facility does not exist on the west side of the street directly adjacent to WSDOT Limited Access ROW, see
Exhibit B1.

LUA18-000669
SE 76th (NE 48th) St Street Conditions:
The existing cross street conditions at SE 76th (NE 48th) St consist of a three lane roadway with center left
turn lane. Existing 5-foot wide sidewalks are present on the north and south sides of the street. For existing
conditions within the Lake Washington Blvd NE vicinity, see Exhibit B1.
PROPOSED
NE 44th St / Lake Washington Blvd N Street Improvements at Location of Modified Street Standard
Future land use development of the undeveloped and underdeveloped parcels located east and west of NE
44th St / Lake Washington Blvd N will warrant intersection improvements at N 43rd St intersection. At this
time WSDOT proposes to provide an interim street section within the area of future intersection
improvements at N 43rd St and construct the street section per City Code to the maximum extent practical
between N 43rd St and Seahawks Way, see Exhibit A2.
An in-street bike lane will be constructed along the south side of the street. To address City concerns
regarding bicycle safety for bicyclists traveling southbound on NE 44th St / Lake Washington Blvd N between
Seahawks Way and N 43rd St, the weaving movements imposed on cyclists and vehicular traffic by the drop
lane condition with a developed inside bike lane at the right turn pocket will not be constructed. To mitigate
not implementing an on street bike lane, a 12-foot wide sidewalk will be constructed on the north side of
the street. Bicyclists can access the existing southbound on street bike lane at the south side of the
intersection with N 43rd St. A contiguous 12-foot wide sidewalk will be constructed on the south side of the
street connecting to existing facilities at May Creek trail vicinity.
An 8-foot wide planter will be constructed on both sides of the street between N 43rd St and Seahawks Way.
Due to anticipated future intersection improvements, WSDOT proposes to not construct planter areas
where future intersection improvements will be warranted once adjacent parcels are redeveloped. This
planned approach does not preclude future planter areas being constructed where feasible as part of future
warranted intersection work or any other future project work that extends beyond the limits of the WSDOT
I-405 Renton to Bellevue Project. Proposed modifications to the street standard for NE 44th St / Lake
Washington Blvd N are as indicated in Table 1, attached.
NE 44th St / 110th Ave SE Improvements – East of I-405 at Location of Modified Standard
WSDOT proposes to meet City street standards to the maximum extent practical within the areas where
roadway profile and alignment adjustments require reconstruction of the curb lines and new or widened
pavement be constructed, see Exhibit B2. The lane widths will be reduced to 11-foot traveled lanes and an
11-foot center two-way left turn lane. A 5-foot wide conventional bike lane will be constructed on both
sides of the street. Additionally, 8-foot planters and 8-foot wide sidewalks will be constructed.
Beyond the limits of proposed reconstruction of the curb lines and new or widened pavement, the project
proposes to reconfigure lane widths within the existing roadway width to accommodate a 5 lane section
with shared use “sharrow” vehicle/bike lanes that will extend to the intersection of NE 43rd Pl / Lincoln Ave
NE. The lane widths will be reduced to 11-foot inside traveled lanes and 11-foot center two-way left turn
lane, 5-foot wide bike lanes will transition to 14-foot wide outside shared use lanes. Existing sidewalks will
remain in place. The eastbound shared use “sharrow” lane will transition to 5-foot wide bike lane at the
north leg of the NE 44th St. / NE 43rd Pl / Lincoln Ave NE intersection where the outside lane is dropped via
right turn only lane to NE 43rd Pl. No modification to the west bound roadway channelization and on-street
parking on NE 44th St / 110th Ave SE is proposed. The proposed configuration meets the recommendations
in the City of Renton Trails and Bicycle Master Plan and will not preclude future private property
redevelopment frontage improvements outside the limits of proposed roadway work for this project.
Proposed modifications to the street standards for NE 44th St are as indicated in Table 1, attached.

I-405 Renton to Bellevue – STREET MODIFICATION
Admin. Modification Request Report & Decision
LUA18-000669
Lake Washington Blvd NE Street Improvements – East of I-405 at Location of Modified Street Standard
WSDOT proposes to realign Lake Washington Blvd NE to the east of the existing roadway and construct a
new northbound general-purpose traffic on-ramp. This ramp terminal intersection will include a
roundabout intersection that intersects with the new Lake Washington Blvd NE alignment approximately
400 feet south of existing SE 76th (NE 48th) St. The realigned portion of Lake Washington Blvd NE will match
into existing Lake Washington Blvd NE approximately 380 feet north of existing SE 76th (NE 48th) St, see
Exhibit B2.
Providing a pedestrian-accessible facility on the west side of the Lake Washington Blvd NE is not desirable
as it is contiguous to the I-405 Limited Access ROW. Pursuant to RMC 4-6-060G, this location is candidate
for exceptions, given establishing a pedestrian facility in this location would be a) contrary to public safety,
b) would be excessively disproportionate to the need or probable use, and c) no long-term need is identified.
Thus WSDOT proposes to not construct sidewalk facilities on the west side of Lake Washington Blvd NE
between the intersection with NE 44th St and the northern project limits on the local street.
An 8-foot wide planter and 8-foot wide sidewalks are proposed along the east side of Lake Washington Blvd
NE from the intersection with NE 44th St to the SE 76th (NE 48th) St intersection.
WSDOT proposes to match the existing roadway and east-side sidewalk section on Lake Washington Blvd
from the intersection with SE 76th (NE 48th) St to the project limits. Constructing sidewalk and planter widths
to the current City street standards would further impact private property and current land use on the
affected parcels, including existing private storm drainage detention facilities.
Proposed Cross Street Improvements – N 43rd St, Seahawks Way, and SE 76th (NE 48th) St:
Anticipated cross street improvements as part of WSDOT I-405 Renton to Bellevue Project are minor and
major grading is not anticipated beyond the intersection area. WSDOT proposes to match existing
conditions at the cross streets and construct, to the maximum extent practical, the minimum intersection
radii as per RMC 4-6-060. This planned approach does not preclude street improvements related to private
development(s) or other City capital projects that are beyond the scope of the WSDOT I-405 Renton to
Bellevue Project from being constructed at a future date. Proposed modifications to the street standard for
N 43rd St, Seahawks Way, and SE 76th (NE 48th) St are as indicated in Table 1, attached.
Proposed Intersections
WSDOT proposes to install four round-a-bouts that will that will be owned and maintained by the City of
Renton. Current design is to have the center of the round-a-bout landscaped, with the option for the City
to install signage which would include the need for power and irrigation. These round-a-bouts are required
to meet City of Renton municipal code including the City’s undergrounding code, RMC 4-6-090.

LUA18-000669
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 Community Design 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. The intent of the
policies are 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 Public Works Transportation section and Community and
Economic Development section reviewed the proposed NE 44th St and the surrounding
area and have determined the modified section as described above is the most
appropriate for the area. This determination was based on the close proximity to I-405,
adjacent properties and the future development within the area.
In order to provide maintainability and appearance of the round-a-bout City staff
recommends a condition that WSDOT shall provide lighting conduit and irrigation to
the round-a-bouts where landscape islands are proposed.
c. Will not be injurious to other property(ies) in the vicinity.
Staff Comment: WSDOT has purchased the portions of the properties surrounding the
proposed onramp at Lake Washington Blvd NE that would be affected by this project.
No additional impacts to other properties have been identified.
d. Conforms to the intent and purpose of the Code.
Staff Comment: See comments under criterions ‘a’ and ‘b’.
e. Can be shown to be justified and required for the use and situation intended; and
Staff Comment: The revised street standards provide a safe design for vehicles and
pedestrians.
f. Will not create adverse impacts to other property(ies) in the vicinity.
Staff Comment: See comments under criterion ‘c’.

Turning radius for streets which include industrial access may increase to 50 feet.
Sidewalks shall be provided on both sides of the street; however, the Administrator may approve sidewalks on one side of the street pursuant to RMC 4-6-006G.
Sidewalks may be designed to be reverse sloped away from the street; provided, that the sidewalks have a maximum long slope of 2% and are designed to drain towards a publicly owned low impact development facility along the roadway instead of directly into the street.
MC - Meets or exceeds Renton Municipal Code
for description of existing conditions, see narrative in Request for Administrative Street Modification. Many existing conditions do not currently meet City of Renton Municipal Code Section 4-6-060. WSDOT will not address existing conditions outside of the project scope footprint as part of this Project
for foot notes 1 through 13 from RMC Section 4-6-060(F)2 see below
A second parking lane may be required by the Administrator.
Class II bicycle facilities (bike lanes) included in roadway width for both sides. Bicycle facilities that are shared travel lanes, Class III bicycle facilities, require less roadway width. Class III travel lanes are a minimum of 14 feet.
Requirement: Either fire sprinklers shall be provided as approved by the Fire Department or a clear roadway area shall be provided for emergency vehicles midblock. All of the clear area must be 20 feet in width for vehicular movement with a minimum length of 50 feet and maximum length of 100 feet, so as to provide emergency access to
homes within 150 feet. Along the clear area only, the planting strip would not be required and the clear area will be in place of the landscaping area.
The City may require different lane width dimensions to address safety concerns or to meet state and federal requirements for state routes or grant funding.
Turning radius dimensions represent the vehicle turning path. The smallest curb radius should be used while maintaining the specified turning radius. Lane width and the presence of a bike lane and parking lane affect a vehicle’s turning path. On streets with more than one lane in that direction of travel, large vehicles may encroach into no
more than one-half of the adjacent travel lane to complete the turn. On Arterials and Collector Arterials, encroachment into oncoming travel lanes is unacceptable. The minimum curb radius is 15 feet.
Minimum design standards may be altered to allow alternative stormwater management and low impact development techniques within the R-O-W by the Department.
Sidewalk width will be 12 feet on both sides in the City Center Community Planning Area. This sidewalk width includes street tree grates for locating street trees. To accomplish low impact development best management practices, permeable pavement may be allowed by the Administrator.
Sidewalk areas may be required at a wider width to accommodate required multi-use path facilities when a Class I multi-use path is required within a street R-O-W by the Department. The width of a required 5-foot bicycle lane will be transferred to the sidewalk area to create a Class I multi-use path. To accomplish low impact development best management practices permeable pavement may be allowed by the Administrator.
Maintenance Responsibilities. Unless otherwise agreed upon by the City of Renton, maintenance of landscaping within the planting strip area, including but not limited to elements such as groundcover, turf, softscape, and hardscape, is the responsibility of the adjacent property owner. Maintenance for street trees within the public right-of-
way shall be the responsibility of the City of Renton.
Planting strips may be reduced if one of the following conditions is met: (a) when R-O-W acquisition is problematic; or (b) when critical areas would be impacted. If approved, a permanent alternative landscaped area should be provided equal to or greater than the allowed planting strip area reduction that is in addition to any minimum
existing code requirements.

Intersection Radii10
At the intersection of two classes of streets, the radius for the higher class street is to be
used. Where larger trucks, transit and school buses are anticipated, further design will be
required to determine an adequate radius. The minimum curb radius is 15'.
0.5 – 15%, greater than 15% only allowed
