During review of the subject submittal it was found that the following information, corrections, or
clarifications will need to be addressed:
1.Please provide a storm detention system worksheet. The worksheet is available in the City’s handout for
Storm Water Management #E72. The handout is available at www.ci.edmonds.wa.us, under the Engineering
Division of the Development Services Department.
2.Revise the impervious surface calculations for the house to include the roof overhang and make adjustments
to the sizing of the detention system accordingly. Also, impervious surface calculations have been provided
on the site plan twice and both calculations are different. Please revise.
3.Show the existing catch basin in the City right-of-way that will accept the outfall from the on-site detention
system.
4.Provide rim and invert elevations for all catch basins, including the existing CB in the right-of-way. Please
also provide rim and i.e.’s for the trench drain at the garage.
5.The footing drains shall not tie into the storm detention system. Indicate on the site plan where the footing
drains will outfall to. They can tie into the outfall of the detention system, on private property or drain to an
on-site drywell.
6.Show the location of the water service line from the meter to the house.
7.Show the location of the 6” sewer lateral from the main to the property line and the 4” side sewer from the

line.
c.A 4” cleanout shall be provided at the house.
8.Pursuant to the Edmonds Community Development Code 18.90 sidewalks are required as a condition of
development approval. Revise the site plan to include 5’ sidewalks along the property frontage, to be
constructed per City standard details E2.8 and E2.13. Standard details are available at
www.ci.edmonds.wa.us, under the Engineering Division of the Development Services Department.
9. Please also add a note to the plans that states the engineering inspector will make a determination during
