Record low water levels in the Black River and Lake Michigan necessitated maintenance dredging efforts to keep the waterways navigable for the local boating industry.

Obtaining accurate bathymetric data was essential to the efficiency and timeliness of the project.  Even while surface water elevations were in constant flux due to weather conditions and hydrostatic forces associated with riparian waters and Lake Michigan, the GPS based bathymetric survey system was able to produce quality control checks of less than one tenth of one foot throughout project sites.  

Abonmarche was contacted by the Berrien County Road Commission to design and construct this single span structure.  The original structure was an earth filled arch requiring special SHPO approvals before it could be removed. The environmental review uncovered an endangered species habitat at the bridge location. Abonmarche worked closely with the MDEQ to ensure the habitat of the endangered bat was not affected by the construction and that the construction phasing did not impact breeding patterns.

Over the past several years, Abonmarche has designed and provided construction administration for a series of non-motorized bikeway and pedestrian trails for the City of Portage in Michigan. 

Among the projects are:
Milham Avenue Bikeway - a recreational path connecting commercial, industrial and school areas with easy access to other existing non-motorized trail systems.

For a number of years, the Arts District has been considered one of Benton Harbor’s greatest opportunities for revitalization within the heart of this economically and demographically depressed region. The project, part of the State of Michigan’s “Cool Cities” initiative, encompasses six city blocks, which were characterized by deteriorating infrastructure, crumbling buildings and a number of environmentally sensitive areas.

In an effort to gain greater efficiency from the 15 facilities Whirlpool Corporation operates in and around the Saint Joseph/Benton Harbor area, the company announced a consolidation effort in late 2010. The center-piece of this effort is the creation of a campus in downtown Benton Harbor consisting of three- three story office buildings and an amenities building. Additionally, the design will incorporate green elements, allowing the company to seek LEED Gold certification.
