The City of Kent Drainage Master Plan has been prepared by the Public Works Department Environmental Engineering Section along with a team of consultant engineering firms to address citywide update needs to its stormwater management plan and program. The plan evaluates and recommends drainage facility capital improvement needs to reduce flood risks, improve water quality, enhance fish passage and instream/riparian habitats, and to efficiently serve planned growth.
