"a STO RM WATE R REVIEW COMMENTS
'`" City of Edmonds
Engineering Division
To: Engineering Reviewer
Date: February 13, 2018
Project Name: Graphite Art Studio
Permit Number: BLD20171841
Address: 202 Main St.
Review Type: Civil Construction
Submittal Date: 12/28/2017
Reviewer: Zack Richardson, PE
City of Edmonds, Stormwater Engineer
Recommendation: Drainage report was generally sufficient and does not need to be
resubmitted unless changes to the plans necessitate revisions to the report; revisions to
the plans are required. I recommend that BLD20171841 be withheld until the
comments below are adequately addressed.
Review Comments:
1. C2.1: Show extents of the storm drain demolition/removal
2. C3.1: Provide unique identifiers (numbers or letters) for each new or altered CB.
3. C3.1: Revise plans as needed to more clearly show how Main St. runoff will be
collected:
a. Revise and/or show more grading to demonstrate that the existing CB will
be the low point, OR
b. Provide new/replaced CB at low point before bulb -out.
4. C3.1: Revise basement drainage note to read "Basement drainage to sanitary
sewer per plumbing plan"
5. C3.1: The wye connection for the alley -side footing drains must occur on -site or
at a CB; revise plans as needed.
6. C3.1: It appears that there is an additional City storm drain connection upstream
of the revised alley CB which is not reflected on the plans; see GIS screenshot
below. Field verify and update plans (or provide written response) as needed.
a. Engineer should verify that a Type I is still structurally sufficient for the
proposed connection configuration.

7. C3.2: It appears that the dead-end configuration of the detention tank requires
the installation of an air vent pipe between the top of tank and control structure
manhole. Provide pipe or written response to address this concern.
a. Reviewer believes that air will be trapped in the top of the tank once the
pipe fills above the top of the 36" pipe; therefore, runoff will not be able to
push into the tank to utilize the upper 2' of storage unless this air has a
release point.
b. An open grate vent/cleanout pipe from the top of the tank to the surface
may serve the same purpose.
8. C3.2: Provide bedding and subgrade information, as needed for construction,
below the detention tank.
9. C3.2: Provide additional detail and/or notes to clarify how/what the detention tank
end cap materials and method for securing in -place will be.
10. SH Sheets: Structural sheets generally directs to move foundation/footing to
bottom of detention tank, but detail on civil plans suggested this needs to go to
the bottom of the control structure, which is lower. Update notes on SH sheets,
or detail on civil sheets, to be consistent with each other.
