Engineering Plan Review Comments
SEWER
1)The plans indicate that the existing side sewer and lateral is proposed to be reused.The sewer will need
to be inspected by the City’s Public Works department to determine if it can be reused. Contact
Edmonds sewer division, 425-771-0235.
a.If the lateralcannot be reused, anew connectionwill be required. The connection at the main
will need to be a romac inserta teeinstalled by the contractor (not the City of Edmonds).
b.If the lateral is to be re-used, show the installation of a 6”sewer cleanout at the property line,
such that thecleanout is located within the City right-of-way.
2)Show a 6” cleanout at the property line. Please add a note that the 6” cleanout at the property line will
have a 12” cast iron lamphole cover with ½” hexbolts.
STORM
1)Due to the slopes, please provide a Geotechnical Report that addresses the following items.
a.The location of theproposed infiltration of the drywell.
b.The location of the detention pipe. Please make sure that the Geotechnical Engineer comments
on the size of thepipe. To install a 72”pipe will require significant digging close to the slope.
c.The proposed locationof thestockpile. Typically the stock piles are placed away from slopes.
2)Please note what size yard drain will be installed in the drivewayand that it is drive-rated.
3)The out pipe in the yard drain in the driveway is showing 1.99’of cover. Please revise the invert
elevation such that there is a minimum of 2’of cover.
4)The yard drainin the driveway shall be private. Please relocate the yard draincompletely on private
property.
5)Please show how the surface waterrunoff from the driveway will be directed to the onsite stormwater
management system (i.e. directional flow arrowsto the yard drain).
a.Show the noteabout the drainage of the drivewayon sheet 3 on this sheet.

Engineering Plan Review Comments
Comments by the City Stormwater Engineer Program Manager, Jerry Shuster, PE–emailed 9/22/15.
Storm Drainage Report, RAM Engineering 8/14/2015
Section E.
WWHM2012 has had several updates since the 2015/03/18 version (used in the report).Please
download the most current version (Clear Creek Solutions website) and use it for this project.
Section 5.7.4.2 of the Edmonds Stormwater Code Supplementstates that the minimum orifice size for a
detention system is 0.5 inches, an orifice smaller than this is proposed in the report.As stated in Section
3.2.4 of the 2005 Ecology Stormwater Management Manual for Western Washington, if the allowable
discharge cannot be met even when the live storage depth is reduced to 3 feet using a 0.5 inch orifice,
that’s all that is expected.The allowable discharge rates can be rounded to 0.009, 0.018, and 0.042 cfs,
if that helps.
Plans
Once a notched weir has been modeled for compliance, place the depth and width on the riser pipe
shown the Plan Sheet GN-01.
