City proposes restoration, five-year monitoring to offset 2,855 sq ft wetland-buffer impact

City planning staff presented a mitigation plan to offset approximately 2,855 square feet of wetland buffer impacts tied to the replacement of Lift Station 1A in Crescent Creek Park.

"It fully mitigates the 2,855 square feet of proposed buffer impacts," Catherine Schaeffer said, summarizing the restoration and enhancement components. Staff described removal of invasive species, planting a mix of roughly 50 native trees and shrubs (listed by staff as including pine and shrub species such as Oregon grape, snowberry, twinberry and thimbleberry) and stabilizing soils to increase filtration capacity and habitat value.

Schaeffer said the restored area will be monitored for five years with annual reporting and replacement of plantings as needed and continued invasive species control. Staff framed these actions as intended to ensure "no net loss of shoreline ecological functions" rather than one-time planting.
