City of Mercer Island / Public Works / Roadway, Trails & Rights-of-Way

Roadway, Trails & Rights-of-Way

The Right-of-Way Team is charged with keeping the City's roads, sidewalks, paths and trails safe for public use.  The Team is responsible for the maintenance of 84 miles of public roads, uncounted acres of undeveloped rights-of-way, storm drains, street lighting, traffic signage, 4 acres of planter beds, 54 miles of trails and paths, several footbridges, 3000 stairs, and sidewalks throughout the Island.

Roadway Maintenance Services

Services include patching holes, repairing edge failures, smoothing depressions, grading gravel roads, mowing & brushing rights-of-way, street signage, street lighting, traffic signals, storm event inspections, and catch basin and ditch cleaning.  In addition, 8 curb miles of roadway in the Town Center are swept 36 times per year, 49 curb miles of arterial streets are swept 18 times per year and 92 curb miles of residential streets are swept 2 times each year. 

Urban Forest and Vegetation Management

Services include  pruning, tree trimming, replanting of areas to maintain erosion control and aesthetics and tree canopy, mowing and brushing of arterial shoulders, and hazardous tree evaluations to ensure safe passage is provided on all City streets, trails, paths and sidewalks. 
 

Planter Bed Maintenance

Services include weed control done by hand with minimal chemical applications, fertilization, irrigation maintenance, pruning and plant replacement to ensure the City's planter beds and beautification areas are maintained in an economical and aesthetic state. 

Pedestrian & Bicycle Facilities Maintenance

Services include general trail maintenance, barrier installations and maintenance, repair or replacement of steps, bridges and retaining walls, repairing and clearing vegetation from sidewalks and paved paths.

Icy or Snowy Roads

The Public Works Departmentís de-icing system got its inaugural use in December 2009: crews spray down a liquid before freezing begins to prevent ice from forming on about 8.5 miles of roadway. Heavy icing resulting from major winter storms still requires the use of sand and salt. Learn more about the City's Snow and Ice Response Plan, and view maps of priority areas.

To report hazardous road conditions, flooding, fallen trees, or other dangers in the public-right-of-way, call the Public Works Department at (206) 275-7608 during work hours, or use the City's 24/7 dispatch number (425) 577-5656 after-hours and on weekends.
