During review of the subject submittal, it was found that the following information, corrections,
or clarifications would need to be addressed. Our handouts can be found online at the City of
Edmonds web site www.ci.edmonds.wa.us under City Government/Development
Services/Engineering Division.
General Comments:
1.The Stormwater Management Code was updated on June 1, 2010. The changes to the code have made
some minor changes to how impervious surface is categorized and measured. I have attached the new
handout E72 for reference. If the total of new plus non-exempt replaced impervious surface is 2000vsf
or more then a stormwater management facility must be used. As I have not quite finished the Handout
regarding sizing etc. yet, please let me know if the project is over 2000sf and I will email you the
information that you will need. I apologize for not having that information readily available.
2.Please provide a separate drainage plan.
3.It appears that changes to the drainage of the existing driveway direct the flow to a catch basin that is
south of the property. Does the existing drainage system drain to that catch basin? Will the new
impervious surface be directed to this CB also?
4.CB located to the south of property is on private property. Is there an easement allowing the Lintons to
cross the adjoining property for access to the storm system or is this an existing condition?
5.Will the piping be replaced between all the catch basins? Please label pipe as existing or new. For all
new pipe label with material of pipe, size and length.
6.All new catch basins and drains need to be labeled with type of catch basin or drain, rim and invert
elevations.
7.Does any of the runoff from the existing or new impervious surface flow into the 4” drain line that
outfalls over the BSNF right of way?
8.In the geotech report there are references to directing some of the drainage to the system that outfalls to
BSNF. On page 7 there is a recommendation to extend the existing drain to the base of the slope and

that the outfall area be armored. Also it is recommended that the d/w and residence drains be
investigated and the outfall be directed to this outfall. Please comment on whether these
recommendations will be followed. Plan appears to indicate that is not the case.
9.Please consider the removal of any portion of the driveway when determining impervious surface
calculations. (if the only disturbance to the asphalt is replacing the cbs then no need to count it).
10.Please label tightline and downspouts drain lines and show where they connect to system.
11.Please add note to plan “Compost amendment required to all disturbed and converted pervious areas”.
This is a new requirement for all sites.
12.Please add note to plan that “All erosion and sediment control will meet recommendations in Geotech
report.”
13.Please add a temporary erosion sediment control method along the south property line where
construction will take place. All erosion and sediment control must be consistant with the City of
Edmonds Standard Details, please call out standard detail reference # for all tesc methods. Details
available on the City website.
14. Show location of side sewer from sewer main to house and water line from meter to house.
15. Indicate the area of disturbance.
16. Add grading amount (both cut and fill if applicable) to plan sheet.
17. Please shade or hatch “new entry”.
18. Please label areas around front of residence. I think they are landscaped areas?
19. Please indicate existing and proposed grade if there are to be changes. If not, a note on the plans that
the stating no change in existing grade would be sufficient.
20.In the Impervious Surface calcs you list a “proposed uncovered deck”. Will it be constructed of an
impervious material? If so, please call out material on plans. Decks made of wood slats are not
considered impervious in our code.
21.Please show on plans the location intended for stock piling of construction related materials.
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.
