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.ci.edmonds.wa.us by clicking City Government / City
Department / Public Works / Engineering Division:
Please Note: Building Handouts do not include updated Engineering Division Requirements. Refer to
Engineering Handouts for all Engineering Requirements.
General:
1. 2/7/12 Done
Plot Plan:
2. 2/14/12 Please review the example. The plot or site plan needs to show the location of all
the utilities and stormwater system but does not need to include the details (length, size,
etc.). I have attached an example.
3. 2/14/12 Revise to reflect new calculations. You can add in a line that states the 1991
sports court has a stormwater waiver with the date of the waiver. The impervious surface
calculation box from the Stormwater Management Handout #E72 Worksheet must be
included on this plan.
4. 2/14/12 Label garage.
Grading/Tesc Plan
5. 2/14/12 Existing and proposed topos are not distinguishable. Use different line types.
The grading and erosion control plan should only show an outline of the house to be
demolished and an outline of the proposed house to show the areas of grade change. No
other details of the structure or driveway etc. are needed on this plan unless they are to
remain. Please remove the proposed asphalt from this plan. Please note the square
footage, material and year of its construction on any areas that are to remain. If any
DATE FAXED/E-MAILED 2/14/2012 PAGE _1__ OF _3_
existing areas are to be removed and replaced, they should be labeled as such and
included in the clearing limits for demolition.
6. 2/14/12 An interceptor swale can not be constructed within a wetland or wetland buffer
area. Please replace with an alternate erosion control measure. All erosion and sediment
control measures shall be shown on the plan. Details of each type of measure used shall
be included with the plan. Please remove the catch basin insert detail and replace with
City of Edmonds detail E1.3. All details shall be consistent with City of Edmonds standard
details.
7. 2/14/12 Some areas labeled (TBR) are not included in the clearing limits. Please expand
clearing limits to include any areas of soil disturbance, including the area where the utilities
will be installed.
8. Please show where the existing utilities will be capped during the demolition.
9. Add the bottom of footing elevation for the area (or areas, if different elevations) of the
structure.
10. Under Contractor Responsibility.. please add the note; The contractor is required to have
on-call a Certified Erosion Sediment Control Lead (CECSL) immediately available onsite to
assess conditions in major storm events and /or when requested by the Engineering
Inspector.
11. Under Permanent Cover please add the comment All disturbed soils that will not
become impervious surfaces shall be compost amended in accordance with City of
Edmonds Handout E72 C.
Stormwater/Utility Plan:
2/14/12 Please submit revised Stormwater Plan. Note: Stormwater system can not be
constructed in the wetland buffer. Stormwater system must be connected to the city storm water
main or can go to infiltration outside of the wetland buffer if a soils test using the approved methods
in the Stormwater Supplement shows adequate infiltration per Supplement requirements.
2/7/12: The submitted plan does not seem to be in agreement with the calculations for the storm
system requirements. If the following is true then the new impervious surface is sf and is not
regulated by the storm water code.
12. The stormwater system shall be sized in one of two ways:
a. The simplified sizing chart located in the Stormwater Handout E72A. If you choose
to use the simplified sizing chart, please review the section Design and
Construction Requirements. A system detail shall be provided consistent with the
example shown in handout. 2/14/12Use the detail in the E72 A Handout to add all
rim and invert elevations and other sizing. If simplified sizing is used, a stormwater
report is not required.
DATE FAXED/E-MAILED 2/14/2012 PAGE _2__ OF _3_
b. If you choose to use a detention size not listed on the chart 2/14/12 (e.g. a different
size catch basin or manhole, only one manhole, etc), the system must be designed
by a Civil Engineer. Calculations and a detail of the system are required.
13. All stormwater catch basins, yard drains etc. shall be noted with rim and invert elevations.
14. All regulated impervious surface must be connected to the detention system. See
Stormwater Management Handout Worksheet (# E72)to determined the regulated
impervious surface on the property.
15. 2/14/12 Please revise. Impervious surface calculations from worksheet are required on this
plan.
16. 2/14/12 Not done. All pipe, storm and other utilities, shall be noted with size, length and
material.
17. 2/14/12 Not done. All storm and utilities shall be shown from connection to City systems to
connection at residence.
18. 2/14/12 Not done. Sewer shall have a 4 cleanout at house and a 6 cleanout at property
or easement line.
19. 2/14/12 Not done. Invert elevations shall be called out for Sewer cleanouts to verify slope.
20. 2/14/12 Not done. Label any existing utilities or connections as existing.
21. 2/14/12 Under General Notes on Drainage plan sheet please remove #10, #19.
22. 2/14/12 Please add to #18 after hydroseeded or stabilized consistent with City of
