Hello Jill Ding,
We would like to discuss the May Creek South Trail (SEPA #202501971) at 4260 Lake
Washington Blvd, Renton, WA 98059, on behalf of Jason Lederer. The Washington Department
of Fish and Wildlife (WDFW) is responsible for preserving, protecting, and perpetuating the
state’s fish, wildlife, and ecosystems while providing sustainable recreational and commercial
opportunities for fish and wildlife. Recognizing our responsibilities, we will submit the
comments for the May Creek South Trail. Other comments may be offered in the future.
Fish and Wildlife Resources and Recommendations:
• The applicant proposes to install a boardwalk over a wetland associated with a
regulated stream. Given the proximity of these developments to May Creek, which is
known for salmonids utilizing this area, the Department is concerned that the impacts
on this regulated wetland may adversely impact fish and their aquatic habitat (WAC
220-660-100).
• At the 90 percent design phase, we would like to see the following concerns addressed:
o We want to ensure that the design will withstand a 100-year flow and counter-
scour measures. The North bank abutment should be farther landward from the
100-year flood. We recognize the restriction of placement due to the wetlands,
but can the bridge be angled differently to increase the setback of this
abutment?

o We request additional information on the abutment pile foundations (Sheet S-6),
including the depth and substrate composition.
o If cutting down trees is part of the plan, we would like to see them utilized on-
site, such as for making benches or fencing, for example, or Large Woody
Material (LWM) in the wetland system.
o Can we obtain more information on the pin piles, such as planned depth, and are
they as far apart as possible to minimize impacts to the substrate?
o Where is the placement of the new stormwater facility or outfall? On page C-9, a
73 LF 12” HDPE is referenced. We would like to know how far outside the 100-
year floodplain it is, and whether a T-Diffuser or a dissipation pad is planned. We
would like to know the expected discharge rate.
o Is the zig-zag pattern over the wetland a necessary part of the design, or can it
be straightened to minimize overwater coverage?
o We require complete plans on any new 12” culverts referenced on pages C-11-
12, including location, amount of water they’re conveying, and purpose.
• Finally, if you have any questions or want technical feedback on project design at any
stage of the planning process, you may contact your local habitat biologist, Maria
McNaughton (maria.mcnaughton@dfw.wa.gov or 360-890-2975).
Thank you for taking the time to consider our comments on this proposal, which aim to better
align it with state regulations and the best available science for fish and wildlife habitats and
ecosystems. Please do not hesitate to contact me with any questions or if you require resources
during this process.
Sincerely,
