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.edmondswa.gov by choosing Permit Assistance.
Site Plan:
1. The site plan needs to show the location of all the proposed utilities and stormwater system but
does not need to include the details (length, size, etc.). I have attached an example.
2. Call out width of sidewalk.
3. Add note to plan: Frontage improvements may be required. An assessment of the condition of
the existing curb and sidewalk will be determined on site by the engineering inspector. Curb or
Sidewalk in poor condition or damaged by construction activities shall require replacement.
Add City of Edmonds Standard Details E 2.8 and E 2.13 to plans. (Okay to add to civil detail
sheet).
4. Masonry pavers are called out for walkway in some areas and landscape pavers in others.
Civils and drainage plan state these areas will be permeable pavers but also note gravel
walkway in impervious surface calculations. Please confer and revise to provide consistent
plans.
5. Impervious surface calculations are different that calculations on civils and in drainage plan.
Please confer and revise to provide consistent plans.
6. Please remove reference to trench drain. This will be temporary measure during construction
so only needs to be shown on tesc plan.
7. Grade elevations and contour lines. The city does not require that both are used. A choice
between the two is provided. It is preferable to use all actual grade elevations for all notations,
including the height calculations.
8. Under Project Site Data, Easements, a reference is made to a sanitary sewer easement and a
an access easement. Please show on the site plan. There is shown on the plan an Emerald
Hills Utility Easement called out though. Please add to this section.
9. Please show the proposed contours on the site plan. This plan should reflect the final
conditions.

Stormwater:
1. Rim and invert elevations shall be provided for all connections to verify slopes. This
includes connections at catch basins, manholes, drywells, walls and clean-outs.
2. Note size, length and material of all pipe. Under driving surfaces pipe must be buried 2ft
from top of pipe to wearing course or must be ductile iron.
3. Civil Plans may be scaled 1:10 if desired for clarity.
4. Footing drains shall not connect to the stormwater management system. Add separate
drywell or other means to collect water from footing drains.
5. Impervious surface calculations are different that calculations on the site plan. Please
confer and revise to provide consistent plans.
6. Masonry pavers are called out for walkway in some areas and landscape pavers in others
on the Site plan. Civils and drainage plan show these areas as permeable pavers. Gravel
walkway is called out in impervious surface calculations but not shown on any plan. Please
confer and revise to provide consistent plans and calculations.
7. Please provide detail or cut sheet for permeable pavers proposed.
8. Please provide detail for Segmental Block wall.
9. Interceptor trenches are shown on this plan. In the Liu report (pg 8) interceptor trenches
are discussed as a temporary bmp during construction but not as a permanent drainage
option. The report states that all drainage shall be piped. Groundwater cannot be
discharged into the infiltration system. If using interceptor trenches for tesc, please show
on Grading/TESC plan.
10. Please provide elevations of pipe at any crossings.
11. Per 12/1/12 Liu report, pg 5, infiltration trench shall be excavated to a depth of 5.5ft.
Driveway profile shows the bottom of trench less than 5 ft deep. Please revise depth of
trench.
12. Infiltration trenches located under driving areas shall have 2 ft cover from top of wearing
course to the top of pipe. Please revise depth of pipe.
13. Under Storm Drainage Notes please remove # 5. CDF is not allowed in the right of way.
14. All CB;s with depth over 5ft shall be Type 2 or larger. Please revise plans and provide
detail.
Utilities:
Water:
1. Call out size of water meter and whether existing or proposed. A 1 meter may be
necessary if fire sprinkling is required by the Fire Marshall.
2. Call out size, material and length of water service line. For fire sprinkling requirements
water line on property must be 1 ½.
3. Under Water Notes, please remove #12.
Sewer:
1. Show 4side sewer clean out at house connection and 6 clean out at property line. Clean
out at property line is required to have a 12 locking cast iron lamphole cover. Please note
on plans.

2. Add rim/invert elevations at both clean outs and call out length of pipe to verify minimum
slope of 2% is achieved.
3. Call out material and size of pipe. Under driving surfaces pipe must be buried 2ft from top
of pipe to wearing course or must be ductile iron.
4. Is sewer lateral from main existing? If not, please provide all details for construction.
5. Under Sanitary Sewer Notes. Please remove Backfill above bedding shall be CDF.
6. Please call out elevations at point of crossing other pipe.
Grading/TESC Plan:
Erosion Control:
1. Please show location of stockpile(s) on plan.
2. Add note to plans: All disturbed areas on and off site shall be compost amended to meet
requirements of BMP T5.13 in the Stormwater Manual, Vol V, Chapter 5.
Grading:
1. Add bottom of footing (bof) elevation or slab elevation for elevation area of structure and
garage.
2. Grading amount looks closer to 1900 or more cyds but bof elevation information may
provide the explanation of why 1500 cyds is given. If not, please revise.
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.
