The Indian Creek Trunk Sewer of Marion is a vital utility connection in the Cedar Rapids–Marion area. Following Indian Creek and passing through Faulkes Heritage Woods, sewer construction activities in these areas requires careful and appropriate engagement with potentially regulated natural resources as well as state and federal agencies that may regulate and permit development within these areas.

For the unavoidable disturbances to wetlands and other regulated natural resources, Impact7G coordinated appropriate and expedited permitting, on behalf of the City, with the Army Corps of Engineers, the Iowa DNR and the U.S. Fish and Wildlife Services. Impact7G worked with the client to identify avenues of avoidance and minimization, as well as to develop appropriate mitigation, such as wetlands and habitat for the Indiana Bat.
