PROJECT DESCRIPTION: The applicant is requesting Environmental (SEPA) Review for improvements
to approximately 2,050 lineal feet of sewer main. The sewer line would be improved through a mix of parallel HDPE
pipelines and rehabilitation of the existing line using a cured-in-place lining technology. In addition, improvements are
proposed to the 37,574 square foot maintenance access road and slope stability measures are proposed to alleviate
erosion in the future. The project site includes Thunder Hills Creek, a type Np stream with a 75-foot buffer, and seven
tributary streams, all classified as Type Ns streams with 50-foot buffers. There are six wetlands (Wetlands A-F). Of the
six wetlands, four (Wetlands B, D, E, and F) would have a standard buffer of 100 feet, Wetland A would have a standard
buffer of 75 feet, and Wetland C would have a standard buffer of 50 feet. The proposal would include 20,703 square feet
of temporary wetland and stream buffer impacts, 1,332 square feet of wetland impacts (Wetland E and F), and 41,000
permanent buffer impacts including the removal of 36 trees. The project site includes RM-F and R-8 zoning designations.
Access to the site would be provided via a gated entrance off of Grant Ave S and S 18th St as well as an existing entrance
