AN ORDINANCE approving the City of Enumclaw 2016 Comprehensive General Sewer Plan with Amendments 1-3.
body
STATEMENT OF FACTS:
1. King County has adopted K.C.C. chapter 13.24, which requires approval of comprehensive plans for water and sewer utilities that provide service in unincorporated King County as a prerequisite for operating in unincorporated King County, receiving approval for annexation proposals, granting right of way franchises, and approving right of way construction permits. K.C.C. chapter 13.24 prescribes the requirements for approval of such plans, including consistency with state and local planning requirements.
2. King County has not previously approved a wastewater plan for the city of Enumclaw. King County regulations require sanitary sewer system plans to be updated every six years.
3. The city of Enumclaw wastewater system has a service area within unincorporated King County and has adopted a comprehensive wastewater system plan ("the plan").
4. The city of Enumclaw wastewater system plan proposes to locate a sanitary sewer facility on a Rural designated property.
5. King County has adopted a Comprehensive Plan that includes policies F-402 through F-453, the applicable portions of which address sanitary sewer policies for facilities and services. These sanitary sewer policies call for consistency with other adopted plans, pursuit of reclaimed water, water conservation, protection of water resources, and when a sanitary sewer facility is proposed to be located in the Rural Area, a finding that its location is technically necessary to provide service to the Urban Growth Area.
6. K.C.C. chapter 13.24 requires the utilities technical review committee to review and make a recommendation to the King County executive and council on the plan, the requirements under K.C.C. chapter 13.24, consistency with the King County Comprehensive Plan, and when a sanitary sewer facility is proposed to be located in the Rural Area, a finding that its location is technically necessary to provide service to the Urban Growth Area. The utilities technical review committee has reviewed the planning data and system operations and has found:
a. The plan uses population and employment projections consistent with the city of Enumclaw's water system plan estimates which were determined using the King County Countywide Planning Policies (CPPs) Table DP-1 housing targets and Puget Sound Regional Council (PSRC) population projection data;
b. A portion of the system's service area is in unincorporated King County;
c. The sanitary sewer facility proposed to be in the Rural Area is:
(1) limited to serving areas within an Urban Growth Area;
(2) subject to access restrictions precluding service to adjacent rural areas; and
(3) technically necessary to provide service to the Urban Growth Area;
d. The capital facility plan is adequate to meet anticipated facility and service needs;
e. The plan is consistent with applicable Washington state water quality laws; and
f. The plan is consistent with other pertinent county adopted plans and policies.
7. Washington state Department of Ecology approved the 2016 plan on March 3, 2017, and approved amendment 2 on October 11, 2023.
8. Under the State Environmental Policy Act, the city completed:
a. an environmental check list and issued a Determination of Nonsignificance (DNS) for the 2016 plan on March 16, 2016;
b. an environmental check list and issued a DNS for amendment 1 on September 18, 2019 with an Addendum on October 16, 2016:
c. an environmental check list and issued a DNS for amendment 2 on September 6, 2023; and
d. an Addendum to a DNS for the city's Draft Comprehensive Plan Periodic Update and Municipal Code Amendments for amendment 3 on October 30, 2024.
9. The system's operations and facilities meet multiple existing statutory, administrative, and planning standards. As the system's operations, facilities, and planning meet the requirements of the King County Code, and are consistent with the King County Comprehensive Plan, the utilities technical review committee has recommended approval of the plan.
BE IT ORDAINED BY THE COUNCIL OF KING COUNTY:
SECTION 1. The city of Enumclaw 2016 Comprehensive General Sewer Plan
with Amendments 1-3, Attachment A to this ordinance, is hereby approved as a comprehensive wastewater system plan.
