Adopted July 9, 2018

The City of Maple Valley seeks to develop and maintain a multi-modal transportation system that is safe, economically and environmentally sustainable and supports community livability.  Pursuant to State Law (RCW 35.77), the City annually updates the Six-Year Transportation Improvement Program (TIP).  Projects are developed and prioritized based on specific goals to be achieved by the transportation program, consideration of public safety, operational deficiencies, financing, and availability of regional, state and federal grant programs.

The TIP identifies the schedule, cost and financial plan for the transportation improvement projects that the City intends to complete during the six-year period 2019-2024.  The TIP was adopted by the City Council on July 9, 2018 by Resolution R-18-1257. 

The 2019-2024 Transportation Improvement Plan is also available to view at City Hall, 22017 SE Wax Road, Suite 200.
