Edgewater

Edgewater

The Edgewater site is a 64’ long privately owned shoreline along the east side of Muskegon Lake, located along Edgewater Street. Prior to restoration, the shoreline consisted of concrete and debris that had been historically placed.

Restoration of the shoreline included removal of the concrete and installation of a stone toe. Above the stone toe, bioengineered lifts were installed with native shrubs, grasses, and wildflowers. Additionally, whole logs were placed perpendicular to the shoreline to break up ice and create habitat.

As water levels rose, approximately 6-8’ waves reached the shoreline, which were higher than any previously recorded in the area. As a result, shoreline repairs were made un 2015 by adding larger stone to the toe and partially re-building the bioengineered lifts.

Site Summary:

Extremely high water levels has caused flooding along Edgewater drive, which has impacted the shoreline restoration. As an emergency protection measure, the City of Muskegon has placed stone over top of portions of the restored shoreline.

While originally planted as an upland buffer, the plant community has shifted and is now nearly entirely emergent wetland. Emergent plant species such as common arrowhead, white water lily, and bur reed are now growing out of cracks in Edgewater Street.  Several populations of red osier dogwood remain along the shoreline.


Native Mean C=average coefficient of conservatism (C). Each plant is assigned a “C” value, which represents the probability that a plant will occur in an undisturbed area. C values range from 0-10. Wetlands with a native mean C greater than 3.5 are considered “high quality aquatic resources” (USFWS)
FQI=Floristic Quality Inventory, which is an indication of quality of the vegetation at a given site. In general, wetlands with an FQI above 20 are considered “high quality aquatic resources” (USFWS)

Management Recommendations

Invasive species are minimally present at the site.

Due to high water levels, little can be done to manage the site at this time.  It is possible that the City of Muskegon may make repairs to the infrastructure along the lakeshore in this area, and may impact the shoreline restoration. If this occurs, the City should work to create the softest shoreline possible while still protecting infrastructure.

The site should be monitored 2-3 times per year to look for erosion and any invasive plants.
