During review of the above noted application, it was found that the following information, corrections, or
clarifications are needed. Please redline plans or submit three (3) sets of revised plans/documents with a
written response to each of the items below to a Permit Coordinator.
1.Any approach to storm water management other than tying in to City storm system must be discussed and
approved by our Storm Water Engineer, Don Fiene. Please have your Engineer contact Don Fiene as soon
as possible to discuss whether infiltration is a viable option at this location. He can be reached at 425-771-
0220 x-1323 or fiene@ci.edmonds.wa.us.
Per the Edmonds Community Development Code Section 18.30.060, any new development or
redevelopment with more than 2,000 square feet of new impervious surfacing shall be required to provide
storm water quality control. The impervious surface calculations noted on the plans indicate the new
impervious area to be 2465sf and therefore you will be required to install an on-site storm detention system.
Please refer to City handout #E72 available on the City website at www.ci.edmonds.wa.us under
o
Development Services Department then Engineering.
3/17/08 Not done. The new stamped concrete pavement shall be included in the new impervious surface
o
area calculations. Also need to include all impervious surface added after 1977 which City records
indicate includes sports court and 1997 two story addition. Plans can not be reviewed until the
impervious surface corrections are made.
If the new impervious area exceeds 5000sf the storm detention system will need to be designed and
o
stamped by a licensed engineer. Design and calcs will need to be submitted to the City for review by our
Storm Water Program Manager, Blaine Chesterfield.
If Infiltration viable per Don Fiene as noted above; plans need at minimum the following to be reviewed:
Submitted Infiltration report needs to specifically address the amount of new impervious surface that the
o
system is to be handling.
Infiltration detail does not match the system shown on the drainage site plan. Please show correct
o
detail to match system proposed.
Provided invert elevation for outflow catch basin is 106’ but topo at that point is 104’. Please correct
o
invert elevation or show grading changes.
