Certification Program targeting up to 75 rain gardens
installed on private property within the community.
2. Removing existing impervious concrete surfaces at the KVCC
Arcadia Commons Campus and Kalamazoo Valley Museum.
3. Capturing roof runoff at the KVCC Food Innovation Building
Campus along Portage Creek and Axtell Creek for reuse in
growing local vegetables on-site.
4. Replacing existing impervious concrete sidewalk along
Arcadia Creek with pervious pavers to reduce runoff from a
section of the new downtown KRVT (City of Kalamazoo
