DETERMINATION OF NON-SIGNIFICANCE (DNS) 
City of Auburn Comprehensive Plan Sewer Update 
SEP24-0008 

The City of Auburn is issuing a Determination of Non-Significance (DNS) for the following described project. The permit applications and listed studies may be reviewed at the Auburn Department of Community Development at One E Main St., 2nd Floor, Customer Service Center, Auburn, WA 98002 and by visiting www.auburnwa.gov/landuse.

Proposal: The proposed non-project action includes adoption of the Comprehensive Sewer Plan as an element of the city's Comprehensive Plan. The City of Auburn's 2024 Comprehensive Sewer Plan replaces the City of Auburn's 2016 Comprehensive Sewer Plan. The plan examines the existing sewer service area which includes both areas within the city limits and potential annexation areas for the City of Auburn. It addresses policies, design criteria, and recommends improvements to the sewer system within its service area. The plan analyzes the current level of service and identifies important projects necessary to meet city and state standards regarding public health, facility efficiency, and operations and maintenance. The wide range of facility improvements includes repair and replacement, system improvements, facility evaluations, and extensions of the utility to meet future sewer demands. The Comprehensive Sewer Plan is an ongoing element of the city's Comprehensive Plan and serves as a guide for the operation, maintenance and expansion of the utility within the sewer service area, in accordance with the local, County, and State requirements.
