The Amoco site, located on the south shore of Muskegon Lake, was restored in 2010 and 2011. Restoration included removal of foundry fill, including the removal of a historic peninsula to restore Muskegon Lake bottomland.
Along the shoreline, concrete, debris, and rubble was removed and replaced with bioengineering. Native trees, shrubs, grasses, and wildflowers were planted along the shoreline.

Recommended Management: Currently, invasive species are minimally present and have been successfully managed along the shoreline. However, the site should be regularly monitored for invasive species and removed through hand pulling or selective herbicide treatments when they are found. Spotted knapweed and purple loosestrife pose the greatest threat to this site. For more information on invasive plant management, click here.
High water levels have caused the shoreline to recede, and some erosion has begun to occur. High water levels have also reduced the diversity of the vegetation along the shoreline. It is important that the remaining vegetation remain in place, and any mowing along the shoreline should be limited so the plant roots can maximize their ability to reduce erosion from the high water and waves.
The site should be monitored 2-3 times per year to look for erosion and any invasive plants.
