Stormwater Comprehensive Plan 

The Final Mountlake Terrace 2018 Stormwater Comprehensive Plan Update (PDF) is now available.  The Comprehensive Stormwater Plan (Plan) provides guidance for the design, construction, management, and maintenance of the City’s storm system to meet future needs. The Plan also provides information about the City’s existing stormwater infrastructure, current operations and maintenance, regulatory requirements, and funding.   Deficiencies were identified, and a recommended course of action developed to resolve them. It was created in partnership with the 2015 City of Mountlake Terrace Comprehensive Plan and other planning documents adopted by City Council, to ensure a common vision for the future. City Council approved the plan in February 2019.
