Current Public Works Projects

Transportation Gateway Project
The Transportation Gateway Project entails upgrading two City arterials: S. 216th St  between I-5 and 19th and 24th Avenue S. north of S. 216th St, serving transportation network needs for planned development of jobs and housing in Des Moines.  For additional information click here for the project page.

South 216th Street Sidewalk Project
South 216th Street will be widened along this corridor to provide a two-way left turn lane, sidewalks along both sides of the street, and bicycle lanes in each direction.  For additional information click here for the project page.

North Twin Bridge Improvement Project
This Project consists of some footing repairs, a seismic retrofit, and other safety improvements including new bridge railing, approach guardrails, and a widened sidewalk on the west side of the bridge.  For additional information click here for the project page.

Des Moines Creek & Beach Park Construction Projects
The City, in partnership with other agencies has embarked on several projects that will improve Des Moines Beach Park infrastructure, and restore Des Moines Creek by reducing flooding.  For public safety purposes, construction areas within the Park and along the trail must be closed intermittently to pedestrians and vehicles.  For additional information click here for the project page.

Pavement Management Program
This yearly program exists to maintain and preserve the integrity of the City’s existing roadway surfaces through a combination of pavement rehabilitation measures, such as overlays, slurry treatments, and chip seals.  Streets are selected for projects using the City’s Pavement Management System. This system divides the streets into appropriate segments and rates their condition by assigning each street a pavement condition index. Staff is then able to determine the most effective combination of reconstruction, rehabilitation and maintenance measures to fit within a given budget. Reconstruction of streets is extremely costly, and can be delayed when proper preservation techniques are budgeted for and implemented.

Neighborhood Traffic Calming Program
The Neighborhood Traffic Calming Program provides a response to some widely experienced traffic problems such as cut-through traffic, speeding, and security.  Cut through traffic has neither its origin nor its destination within the neighborhood, but rather is passing through the neighborhood on its local streets.  Many motorists (neighborhood residents as well as 'cut throughs') drive too fast on local streets.  Excessive traffic speeds and volumes on local streets impact the quality of life in our neighborhoods.  The installation of traffic calming measures to reduce vehicle speeds and volumes within neighborhoods can enhance neighborhood safety.
Neighborhood consensus and participation are required prior to implementing projects. Available traffic calming measures are listed in the Des Moines Municipal Code and include speed humps, traffic circles, chicanes and others.  Small projects are funded through the City’s Arterial Street Fund.

Des Moines Creek Non-Motorized Trail Extension
The City of Des Moines is planning to extend the Des Moines Creek Trail from Des Moines Beach Park  to the Midway Wastewater Treatment Plant.  The project is currently in the design phase, and construction of this project is anticipated for the spring and summer of 2008, following the completion of the Moines Creek Bridge Project, and other improvements planned for the Beach Park.
This trail link will fully connect with the planned "Westside Trail" being designed by the City of SeaTac as shown on the graphic below.  Trail connections within the park and to the downtown area will be considered during design.  Anticipated trail construction includes approximately one mile of paved pathway, 12' wide, with 2' shoulders and associated signage, drainage and other related improvements.  The trail is planned as a multi-jurisdictional project connecting Puget Sound to Seattle.   This will be a federally funded project with matching funds from the City of Des Moines.  Design of the extension project is being undertaken as a joint effort between of the City of Des Moines Parks Department and the Planning, Public Works and Building Department.  For further information on the status of the project, please call the Public Works Department at 206.870.6522.  Click here to view the proposed trail map.

Annual Guardrail Program
This program is specifically intended to target roadside safety on the City’s street system.  This program will identify and prioritize guardrail candidate locations.  Guardrail candidate locations are those where guardrail is warranted, as determined by the American Association of State Highway and Transportation Officials (AASHTO) – Roadside Design Guide, but where none exists, and locations where the existing guardrail does not meet current design standards and should be upgraded to enhance safety.  It is anticipated that this program will last 6 to 8 years depending on the availability of funds.  At the end of that time frame, the City’s guardrail system should be consistent with current design standards.

Annual Sidewalk Program
This program is intended to specifically target existing sidewalk locations that are in significant need of repair, or that do not meet current City, WSDOT, or ADA Standards.  Typical locations for repair might include curb, gutter, sidewalk, asphalt paths, driveway approaches.  This program is intended to address repairs that are considered too large for normal maintenance activities.   This program will prioritize projects that are near schools, in commercial areas, and at locations with high amounts of pedestrian traffic.  Special consideration will be given to locations with past pedestrian accident history, and at locations where citizen concerns have been received.
