RE: File #22-100735-00-EN
Comment Response Letter
Woodbridge Building B; 3120 S 344th Street, Federal Way
Dear Mr. Spadoni:
ESM Consulting Engineers, LLC, is submitting the following responses to the comment
letter we received from you dated April 6, 2022.
In an effort to provide concise and direct responses, we have copied the review comments
below in italics and our responses are in bold.
Public Works – Development Services Division
Leonard Spadoni, 253-835-2732
1. This is a clear and grade permit only. Only existing and proposed topographical
contours along with Temporary erosion and sedimentation measures to be shown.
Remove all final features from plan.
The final features have been removed from the plan set.
2. Add City of Federal Way file number, 22-100735-00-EN to all sheets.
The file number has been added.
3. How are retained trees identified especially in the field?
All retained trees are located in the Managed Forest Buffer and outside of the
clearing limits, which are delineated with staking, flagging and orange filter fabric
fence or native growth protection fence, as applicable and shown on the plan set.
4. The walls shown are structural in nature so there will be a commercial building
permit required for each wall shown. Retaining wall construction is not a portion
of a clear and grade permit.

The retaining walls have been removed from the early clear and grade permit set.
5. The location of the temporary storm pond will require a retaining wall and will
require a commercial building permit. Given the comments in No. 4 how is this
pond viable?
The proposed temporary sediment pond has been relocated and the grades have
been adjusted to be able to retain onsite stormwater runoff without the retaining
wall construction.
6. Show the BMP’s to prevent illicit discharge from leaving construction storm ponds
discharging offsite.
The clearing limits have been updated to exclude the secondary storm drainage
outlet that will be constructed with the Building B construction plans.
7. A certified erosion and sediment control lead shall be identified.
Rob Overton has been identified as the CESCL for the project in the updated
SWPPP document.

loads meet section 303.
As described in the SWPPP, there are no known impairments for 303(d) listed or
Total Maximum Daily Load (TMDL) for the receiving waterbody. The East Branch
Hylebos Creek is not a 303(d) listed water body.
11. A copy of the fill and grade permit, section 404, from U.S. Army Corps of
Engineers must be submitted.
