Project Details
The city of Grand Haven turned to Abonmarche for assistance in reconstructing Grand Avenue from Harbor Drive to Sheldon Avenue. This route serves as an alternate access to Lake Michigan beaches and the State Park. Pavement deterioration, geometric deficiencies, pedestrian and bicycle safety, an undersized water main, and storm water ponding were the impetus behind the proposed improvements. The project included numerous “land locked” parcels and subdivisions exclusively accessible from Grand Avenue. An extensive traffic maintenance and phasing plan were implemented to maintain property access.
Abonmarche led an extensive public participation process including numerous public meetings and a bus tour for City Council to gain support for the proposed improvements. These improvements included pavement reconstruction, new curb and gutter, design of horizontal and vertical curves to meet AASHTO standards, retaining walls to meet adjacent grades, improved sidewalks and connectivity, and push button activated rapid flashing beacons for key pedestrian crossings. Our team also replaced and upsized the water main from 6” to 12”, replaced the sanitary sewer and lining, and created means for storm water detention through an interconnected system of perforated pipes and leaching basins.
