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 the “Services” tab and
“Permits and Development”.
General
FYI: A stormwater covenant shall be provided for the infiltration facility prior to construction final. If
recording of the short plat is imminent, document will not be required.
Sheet SP-01
1.2. Please remove “Project Notes” section from plan sheet. The notes pertain to the short plat not this
project.
2.Add haul route.
3.Under “Sewer Notes” change “city main” to “OVWSD main”.
4.The easement for the alley crossing the southeast corner of the property must be shown on this plan. The
actual easement legal docs will need to go to the council for approval and acceptance before final
construction approval will be granted for this SFR permit.
5.SDCOs have inverts showing a 4 ft depth. Too small for adequate access for cleaning sfr system. Please
revise to type 1 cb.
6.Flow arrows in driveway show runoff directed to northwest corner but there is no indication of how that
runoff is being conveyed to the infiltration system.
Sheet TP-01
7. Please review sheet for additional call outs and notes needed per earlier emails regarding tesc and protected
areas.

12
b.Timestep
c.Predeveloped conditions
d.Evaluation of flow control duration standard
2.WWHM2012 modeling needs to be updated to include the following:
a.Outlet/overflow structure - current no outlet (other than infiltration) is included in the model
screenshot provided on page E-1 of the Storm Drainage Report (2/23/16); however, sheet RP-
01 in the plan set shows an 8” perforated pipe and an outlet structure
b.Evaluation of the flow control duration standard (Stream Protection Duration) on the Analysis
tab
3.Page E-1 of the Storm Drainage Report (2/23/16) and sheet RP-01 (2/23/16) list “1-1/2-inch to 3/4-
inch washed rock.” According to the Stormwater Management Manual for Western Washington, this
should be “1-1/2 to 1-3/4 inch washed rock.”
4.Typos in the Storm Drainage Report (2/23/16):
a.Page i – “pf” should be “of”
b.Page i – “t” should be removed or changed to a full word
c.Page H-1 – “Infiltratin” should be “Infiltration”
Please resubmit 3 copies of the revised plans/documents to a Development Services Coordinator. Please
contact me at 425-771-0220 if you have specific questions regarding these plan corrections.
