Resubmittals can be made at the Development Services Department on the 2nd floor of City Hall.
Permit Center hours are M, T, Th & F from 8am-4:30pm and on Wednesdays from 8:30am-noon.
City of Edmonds handouts, new updated standard details with new reference numbers, application
and other forms, and development code may be referenced on the City website:
www.edmondswa.gov under Services/Permits and Development.
GFWF.RAL
1) Provide a site plan scaled to 1" = 20'.
2) Remove the plot plan from Sheet A0.01.
3) Sheet A1.00 should be a separate plan set, with the site plan and grading plan.
4) The southern property line appears to not be in the correct location. Please revise the plans
accordingly.
5) Show all City utilities within Walnut Street.
6) Please show and label all existing hard surfaces (patios, decks, walkways, driveway,
rooflines, etc.) on the plans.
7) Please show all proposed new and replaced impervious surfaces (additions, rooflines,
driveway, etc.) on the plans.
a. Please note that meeting or exceeding 2,000 square feet of new and replaced
impervious surfaces triggers stormwater management.
8) Show the extent of the existing driveway, and the extent of the proposed new driveway.
Label any portion of the existing driveway as replaced if you intend to remove to bare soils.
Please note that any new or replaced portions of the driveway will count toward the total
impervious surface area for this project.
9) Consistent with Edmonds Community Development Code 18.80.060, driveway slopes shall
not exceed 14% slope. Please indicate this requirement on the plans.
10) The City would prefer when a driveway is being reconfigured (e.g. change in slope) that the
driveway approach is replaced as well to meet ADA standards. If you intend to replace the
existing driveway approach, it will likely require a 15 foot wing (unlike the typical 6' wing)
on one side and less than a 6 foot wing on the other side to accommodate the slope down to
the driveway approach. Additionally a 2 foot asphalt cut will be required in Walnut Street
when replacing curb/gutter. Please revise the plans accordingly.
11) Submit ROW Permit Application form for replacement of the driveway and/or sidewalk and
curb/gutter.
TESC
1) Show filter fence on the plans and incorporate and reference City standard detail.
2) Show construction entrance on the plans and incorporate and reference City standard detail.
a. Please note that utilizing the existing driveway, or at least a portion extending from
the sidewalk to the house, will qualify as the construction entrance.
b. If the driveway will not be utilized for parking once it is removed prior to be re -
poured, then a construction entrance would not be required.
3) Please show and add a note to the plans that filter socks will be added to any catch basins
downstream from the construction site. Incorporate and reference City standard detail.
4) Please provide the location of any temporary stockpiles during the grading phase of the
additions. Add a note that the stockpile is to be covered within 24 hours
5) Please add a note to the plans that all disturbed soils will be compost amended per BMP
T5.13.
WATER
1) Based on review by the Building Department, the existing 3/a" meter will not provide
sufficient demand for the proposed fixture count for the existing single family plus the
addition. For this reason, the existing meter will need to be upsized to a 1" meter, which will
require a new tap by the City on the City's water main. The applicant will be required to pay
for the new tap on the main and the new meter. Fees are outlined as below:
• Installation of a 1" water meter is $2,970
• With the installation of a larger meter, general facility charges (GFC) will also be
required in the amount of $7,574. (The GFC for the 1" meter is $12,624. A credit for
the existing 3/a" meter GFC is $5,050.)
• Therefore, the total for the 1" water meter installation will amount to $10,544.
2) Please revise plans to include the following:
• Please add a note that a 1" meter is to be installed.
• Show the water meter located in the right-of-way, such that the back of the meter is
on the property line.
• The water meter shall not be located in the driveway or in the sidewalk.
• Please label the pipe material and note tracer wire to be installed on the water service
line.
2) Show that there is a minimum of 3' of horizontal separation between the water service and
dry utilities (i.e. power, phone, gas, cable, etc.).
3) A minimum of 10' of horizontal separation is required between water and sewer lines.
4) Please add a note to the plans that all final restoration shall be completed by the contractor
not the City of Edmonds.
