SUBJECT: May Creek Trail South Project
4260 Lake Washington Blvd N, Renton, WA
LUA25-000091
I have reviewed the application for May Creek Trail located at 4260 Lake Washington Blvd N and
have the following comments:
EXISTING CONDITONS:
The site is approximately 8.21 acres of City of Renton Park/Recreation space. It is fronted by private
property to the north and south, Lake Washington Blvd N to the west, and I-405 to the east. It is
comprised of one king county parcel number 322405-9109.
WATER:
There is no anticipated water utility impact from the proposed development.
SEWER:
There is no anticipated sewer utility impact from the proposed development.
STORM:
There is a section of existing 24-inch stormwater main on the east side of Lake Washington Blvd N
(Project File: SWP2703531), which is a discharge pipe from an existing water quality facility (Facility
ID No. 250055) to the northwest of the project site. There is an existing stream named May Creek
across the project site flowing from the east to west.
STREETS:
The proposed development fronts Lake Washington Blvd N along the west property line. Lake
Washington Blvd N is classified as a Collector Arterial Street. Existing right-of-way (ROW) width
according to the King County Assessor map is 60 feet, consisting of approximately 34-foot paved
road, and on the project side, 10-foot lane, a 5-foot bike lane, 2-foot asphalt edge, and 16-feet of
clear space.

SURFACE WATER
1. Drainage plans and a drainage report complying with the adopted 2022 Renton Surface
Water Design Manual is required. Refer to Figure 1.1.2.A – Flow Chart of the 2022 Renton
Surface Water Design Manual (RSWDM) to determine what type of drainage review is
required for this site. Based on the City of Renton’s flow control map, the site falls within
the Duration Flow Control Standard- Matching existing site conditions and is within the
Lower May Creek Drainage Basin.
a. A Preliminary Technical Information Report (TIR) prepared by WSP, Inc. dated
November 2024 was submitted with the Land Use Application, which was
prepared following the 2022 Renton Surface Water Design Manual (RSWDM).
b. Core Requirement #2, off-site analysis: An offsite analysis was performed by
WSP, Inc on March 15, 2024. The TIR depicts that no evidence of existing or
potential drainage or erosion problems were observed during the field
inspection. Staff concurs with the assessment.
c. Core Requirement #3, per the TIR, exemption #2 for Core Requirement #3 per
RSWDM based on target surfaces that do not exceed 0.15-cfs of difference
between existing and proposed site conditions. Staff concurs with this
assessment. The preliminary analysis is conceptually acceptable and will be
further reviewed as a portion of civil construction permit review.
2. Conveyance, Core Requirement #4: All new conveyance systems constructed as part of
the project must be sized to 2022 RSWDM standards for the total tributary area (onsite and
offsite) that the storm systems serve.
a. The preliminary TIR provided a hydraulic calculation indicating that the
proposed new ditch, culvert and existing RCP storm drain will have the
conveyance capacity meeting 2022 RSWDM standards. Staff concurs with the
assessment.
3. Construction Stormwater Pollution Prevention, Core Requirement #5: The preliminary civil
plan and drainage assessment include an ESC and CSWPP plan.
a. A CSWPP plan was included in the land use permit application, which is
conceptually acceptable. ESC measures shall be included in the TIR and will be
reviewed with Civil Construction Permit application.
4. Water Quality, RSWDM Core Requirement #8: If the new plus replaced pollution generating
impervious (PGIS) surface exceeds 5,000 SF, the applicant will be required to provide basic
water quality treatment.
a. Per TIR, the project is adding 5,230 SF of new impervious surface but only 890
SF of total is considered as PGIS, which is less than 5,000 SF threshold, and the
project will add less than ¾ acre of new PGPS. Therefore, the project is exempt
from Core Requirement #8 and no water quality treatment is required. Staff has
reviewed the analysis and determined it is conceptually acceptable.
5. Appropriate on-site BMPs satisfying Core Requirement #9 will be required to help mitigate
the new runoff created by this development to the maximum extend feasible. On -site BMPs
shall be evaluated as described in Section C.1.3 of the 2022 RSWDM. A preliminary
drainage plan, including the application of on-site BMPs, shall be included with the land
May Creek Trail South Project LUA25-000091 Page 3 of 4

use application, as appliable to the project. The final drainage plan and drainage report
must be submitted with the utility construction permit.
a. The preliminary TIR depicts that the project will implement rock pads as a
dispersion device to discharge concentrated runoff up-slope of the proposed
trail, and the runoff from the proposed trail impervious surface is designed to
sheet flow into the wetlands and May Creek. Staff has reviewed the analysis
and determined it is conceptually acceptable.
6. A geotechnical report for the site is required and shall be submitted with the land use
application. Information concerning the soils, geology, drainage patterns, vegetation
present, water table and soil permeability, with recommendations of appropriate on-site
BMP options with typical designs for the site from the geotechnical engineer, shall be
submitted with the application. The geotechnical report should include an on-site
infiltration test to clearly show if the site is suitable or unsuitable for infiltration.
a. A geotechnical report dated March 3, 2023, completed by PanGeo, Inc., was
provided with the Land Use Application.
b. The report discusses the soil and groundwater characteristics of the site and
provides recommendations for project design and construction. Geotechnical
recommendations presented in this report state that groundwater is at 2-feet
below ground surface with seasonal fluctuations.
7. Construction Storm water General Permit from the Department of Ecology is required
if land disturbance of the site exceeds one acre.
8. No SDC fees will be collected on City-owned properties per RMC 4-1-180.B.2.b.
TRANSPORTATION
1. In accordance with RMC 4-6-060, if the site improvements and/or proposed building
additions exceed an overall valuation of $175,000, the project site(s) shall be required to
meet the City’s Complete Streets Standards.
a) Lake Washington Blvd N is classified as a Collector Arterial Street with an existing right -
of-way (ROW) width of approximately 60 feet. To meet the City’s complete street
standards for Collector Arterial streets with 2 lanes a minimum ROW width of 83 feet is
required. Per RMC 4-6-060 half of street improvements as taken from the ROW
centerline shall be required and include a minimum 46-foot paved road (23 feet each
side), a 0.5-foot curb, an 8-foot planting strip, an 8-foot sidewalk, 2-foot clear space at
back of walk, street trees and storm drainage improvements. Dedication of
approximately 11.5 feet will be required pending final survey. However, an alternate
street section has been designated for this section of Lake Washington Blvd N.,
minimum half street improvements shall consist of a 32-foot paved roadway (16 feet
from centerline) consisting of a 11-foot travel lane and 5-foot bike lane, a 0.5-foot curb,
an 8-foot planting strip, a 12-foot sidewalk, street trees and storm drainage
improvements. Dedication of approximately 6.5 feet will be required pending final
survey. A street modification will be required and shall be included with the land use
application.

a. Due to the adjacent critical areas (e.g., steep slope, wetland) along the east
side of Lake Washington Blvd fronting the project site, the applicant
provides a waiver to only install sidewalk on the northern portion of the May
Creek Trail connection on Lake Washington Blvd N. and no undergrounding
of existing utilities. The applicant provides a modification of the street
standards above to install a 4.5-foot sidewalk, 0.5-foot curb, 5-foot bike
lane, and 11-foot travel lane with the road centerline realignment to the
west, no ROW dedication is proposed. The proposed street section is
considered acceptable, and staff concurs with the proposed waiver and
modification request above.
2. Paving and trench restoration within the City of Renton right of way shall comply with the
City’s Trench Restoration and Street Overlay Requirements.
3. ADA access ramps shall be installed at all street crossings. Ramps shall be shown at each
intersection. Ramps shall be oriented to provide direct pedestrian crossings.
a. No ADA access ramps or pedestrian crossings are proposed per the preliminary
frontage improvement plans. The proposed new sidewalks and trails shall be designed
to meet ADA standards, which will be further reviewed as part of the civil construction
permit application.
GENERAL COMMENTS

ENVIRONMENTAL & DEVELOPMENTAL APPLICATION REVIEW SHEET
Police Comments – Submitted by Sandra Havlik, CEC, Renton Police Department
Police Comments regarding trail proposal:
1. Natural Surveillance
• Clear sightlines: Keep vegetation trimmed back along trails and near the bridge so users can see
ahead and around them.
• Low landscaping along trail: Trim shrubs 2-3 feet and clear tree canopies to 7-8 feet to avoid
hiding spots.
• Lighting: Install appropriate, vandal-resistant lighting along the trail and bridge to encourage safe
use during early morning or evening hours.
• Trail curvature: Design curves to be gentle so they do not block long sightlines. Ideally
pedestrians should be able to see out to 25 feet.
• Bridge transparency: Use open-style railings on the bridge (e.g., metal or cable) so it does not
create blind spots. Per the plans, this does seem to be the type that will be used.
2. Territorial Reinforcement
• Signage: Clear signs marking the trail's entrance, rules, hours, and the bridge as part of the park
system. This will assist our officers to enforce park rules of engagement.
• Defined pathways: Use paving, different materials, or edging to make trails and bridge
approaches look cared for and well monitored.
• Park branding: Consider using park logos or colors on the bridge and trail signs to reinforce that
this is a maintained public space.
3. Access Control
• Trailheads: Install gates or barriers that allow pedestrians and cyclists but prevent unauthorized
vehicles.
• Limit entry points: Keep access predictable and easily monitored, rather than having multiple
unmonitored informal paths.
4. Maintenance
• Keep up on repairs: The trail and bridge need to be maintained on a regular basis so they are
free of graffiti, broken fixtures, and overgrown plants.
• Trash bins: Provide waste receptacles along the trail and near the bridge — regularly emptied.
• Trail surface upkeep: Ensure pathways are free from erosion, tripping hazards, or damage.
5. Target Hardening
• Emergency call stations: If feasible, install emergency call boxes along longer stretches.
• Bridge structure: Use materials resistant to vandalism (e.g., anti-graffiti coatings) and tamper-
proof fixtures.
• CCTV: Consider discreet cameras at trailheads or key junctions, but balance privacy in natural
settings.
6. Community Involvement recommended to keep this an “active” space with intended users and
improve natural surveillance, and ownership of the area.
• Program/Activities: Host nature walks, volunteer cleanup days, and community events to
increase and encourage legitimate use.
• Partnerships: Collaborate with local law enforcement for routine patrols with public works
department and local social services for safety, security, and resources needed for any
encampments that may be set up alongside, or outside the trail area.
The above-mentioned suggestions are from Crime Prevention Through Environmental Design (CPTED)
ideology. CPTED focuses on preventing crime by designing your physical environment to positively
influence human behavior. These are only recommendations based on the CPTED philosophy and if
implemented cannot guarantee that the area will be impervious to crime.
