GENERAL
1) Please submit Side Sewer Permit Application form for the proposed side sewer serving the
ADU.
2) Show sewer invert elevations at proposed ADU and connection to existing to verify a
minimum of 2% slope and 2 feet of cover.
• Label pipe material on the plans.
3) The proposed side sewer to serve the ADU appears to cross proposed underground dry
utilities (power, phone, cable, etc.). A minimum of 12" separation between dry utilities and
sewer must be maintained in perpendicular crossings. Please show this requirement is being
achieved (e.g. cross section).
4) January 28, 2019: Based on review by the Building Department, the existing 3/4" water
meter will not provide sufficient capacity to feed the existing single-family residence
and proposed ADU. 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 as outlined 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.
Please note, the City of Edmonds is currently evaluating GFC's for ADUs. If you
would like to proceed toward issuance of this permit at this time, the fee for the 1"
water meter is $10,544. If you would like to wait until a decision has been made on the
GFC's, which may affect the total cost, that is an option as well.
5) 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.
Please label the pipe material and note tracer wire to be installed on the water
service line.
