Speed TrailerTraffic conditions on residential streets can greatly affect neighborhood livability. When streets are safe and pleasant, quality of life is enhanced. When traffic problems become a daily occurrence, sense of community and personal well-being may become threatened. The City of Maple Valley has developed a Neighborhood Traffic Safety Program (NTSP) to enhance the safety and livability of residential streets in neighborhoods. Under this program, the City's Public Works Department works with residents to help identify neighborhood traffic problems and implement solutions that are both acceptable and appropriate for the residential streets in their neighborhoods.

The City of Maple Valley’s NTCP is based on a two-phase approach. Phase I includes community education, enforcement, less restrictive traffic management measures, such as improved pavement markings and enhanced signage. These relatively simple, and often effective, approaches to solving neighborhood traffic problems are attempted first.

If necessary, and only with neighborhood concurrence, Phase II solutions may be tried. These involve more complex physical construction measures -- speed humps and traffic circles, for example.

Throughout the process, the Public Works Department carefully evaluates the effectiveness of all measures taken and helps prioritize neighborhood requests. However, the ability to conduct neighborhood studies or implement traffic calming measures is limited by the availability of budgeted funds.

Getting Started

The first step in getting started with the NTCP is to complete a Citizen Request Form. The form is available on the City’s website at

Phase I

Once we receive your Citizen Action Request form, the Public Works Department gathers data and studies the situation before recommending the best course of action. This analysis may take several weeks, depending on the complexity of the problems. The Public Works Department will keep neighborhood residents informed findings and recommendations for Phase I solutions.

Phase II

If Phase I solutions are proving ineffective after having been in place for 1 to 2 years, more restrictive traffic calming devices may be considered in Phase II.
