During review of the subject submittal, it was found that the following information, corrections, or
clarifications would need to be addressed. All Handouts referred to in these comments can be accessed at
our website: www.edmondswa.gov/under City Government / Development Services Department /
Engineering Division then scroll down to Handouts:
1)Please show thelocation of theside sewer line on thesite plan.
2)A right of way permitis required for the use of the right of way, attached is a right of way application. Please
fill out and submit with a traffic control plan.
3)
Per Edmonds Community Development Code 18.80.060C, where there is no curb or gutter,the driveway
approach must be constructed with asphalt within the right of way up to the property line. Please identify the
new driveway material within the right of way (asphalt) and on site (asphalt or concrete).
4)Please provide the date of construction forall existing impervious surfaces on the Site Plan.
5)With demolition of the garage,per the plans theconcrete slab will be removed. This takes the area down
tobaresoils and will not be considered as Replacedexempt impervious surfaces.This will make the
section of the new garage/addition New Impervioussurfaces, please make these corrections in the
Impervious Surface Calculationstable.
6)In total, I’ve calculated Non-regulatedimpervious surfaces(existing surfaces to remain) as
approximately 1,920sf and New (Post 1977) impervious surfaces at approximately 2,400sf. For whichall
of the2,400sf ofimpervious surfaces will needto be mitigated by a stormwater management system, i.e.
detention system or infiltration system. Please recalculate the impervious surface numbers and revise
the Impervious Surface Calculations on your site plan.
a)If an infiltration system is proposed,aDrainage Reportis required. Please submit aDrainage Report
by a licensed Geotechnical Engineer.The report should addressthe soil conditions and infiltration
rates. Refer to City handoutE-72B Low Impact Development BMP Simplified Sizingalso the
