Plant Selection

Native Vegetation are adapted to our local climate and conditions and they have many stormwater management benefits.  Their deep roots help water infiltrate into the soil and prevent erosion, prevent erosion, and provide filtration.

Compared to conventional landscapes or turf grass lawns, native plant installations can reduce costs and carbon emissions from maintenance, and reduce or eliminate the need for irrigation, fertilizers, and herbicides.

Approved Plant List

The approved plant list includes species for use in stormwater management installations in Washtenaw County.  Green infrastructure with vegetation not only manages stormwater but can also provide vibrant natural spaces for residents, clients, employees, and visitors to enjoy.

Installation & Maintenance

Proper installation by experienced native landscape contractors is critical to project success. Preventing soil compaction, careful handling of young plants, and watering during establishment will support robust vegetation.

A maintenance plan and control of invasive species is necessary to support healthy native plant communities.  Native plant installations do not need fertilization. Depending on site needs and plant species, common maintenance includes seasonal mowing, prescribed burns, controlled spot herbicide applications, and hand removal of weeds or invasive plants.
