In 2010, $1,492,500 in Great Lakes Restoration Initiative (GLRI) funding was awarded to Macomb County and the Huron-Clinton Metropark Authority to restore the coastal wetlands at Lake St. Clair Metropark in Harrison Township.

Partners in the project included the Clinton River Watershed Council and Wayne State University.

Most of of the project centered around the Point Rosa Marsh area at the southwest corner of the park. The goals of this project were to restore the coastal wetlands by increasing the amount and quality of the landscape. Pre- and post-monitoring included bird, reptile, amphibian, plant and macroinvertebrate surveys.

Upon completion in 2013, the restoration of the plantlife, boardwalks and informative signage were installed, aiding in the water study of this area.
