During review of the subject submittal, it was found that the following information, corrections, or
clarifications would need to be addressed. All Handouts and Standard Details referred to in these
comments can be accessed at our website: www.edmondswa.gov by choosing Permit Assistance:
GENERAL
1.Please provide an itemized engineers cost estimate, including units and unit prices, for both on-site and off-
site (right-of-way) improvements, including all utilities, traffic control, fencing and restoration. Please use
the King County Site Improvement Bond Quantity Worksheet and utilize the write-in sections where
appropriate.
A bond is required to be placed for all erosion control measures and right-of-way improvements. The
·
amount of the bond will be based on 120% of the City approved estimate. The City will inform you of
the appropriate bond amount after review of the cost estimate. Please obtain the appropriate site
improvement bond forms from the City.
Inspection fees for this project will be calculated at 3.3% of the 120% City approved estimate for on and
·
off site improvements.
2.Please add a cover sheet to civils with all general information . Signature block, if provided, should read
City of Edmonds Engineering Division, Construction Sequence, Erosion Control Notes, and General
Notes as applicable using sample language attached to these comments. (Review General Notes provided
on plan to insure they are consistent with the attached sample).
3.Provide all purveyor information for Edmonds utilities on civil coversheet. See COE Handout E28.
4.Please add note to cover sheet stating A separate right-of-way construction permit is required for all work
within the city right-of-way. A ROW permit application with contractors signature shall be provided to the
city.

STORM DRAINAGE
7.Proposed Impervious surface calculations do not appear to include eves, the dumpster pad or the walking
paver area. The walking paver areas are considered impervious. Permeable pavers are a means of
mitigation of the walkway area. (Please contact Stormwater Engineer Jerry Shuster for further information).
Rough calculations from the scaled plan indicate that the total proposed impervious area is closer to 5600 sf.
Please recalculate and revise plans.
8.Please provide a stormwater site classification worksheet for this project. The worksheet can be found in
the Handout E72
(http://www.edmondswa.gov/images/COE/Services/Permits_and_Development/Forms_and_Handouts/E72-
SWM_Erosion_Control-03.05.12.pdf). Based on the amount of new impervious surface proposed, it
appears it will classify as a Category 2 Small Site Project. Please verify.
9.Please provide a stormwater report including the requirements of Chapter 5 of the Edmonds Stormwater
CodeSupplement, (http://www.edmondswa.gov/images/COE/Government/Departments/Public_Works/Sto
rmwater_Utility/pdf/EdmondsStormwaterSupplementFinal20100428.pdf).

Category 2 Small Sites.
