The Dearborn County Council on Wednesday approved a one‑year amendment to an interlocal MS4 agreement with the town of Aurora and renewed planning and zoning’s service arrangement.

Sandy Whitehead, the county’s MS4 coordinator, attended on behalf of Nicole Daley and said Aurora will renew its agreement with the county and include coordinator services; the town agreed to a 3–4 percent increase after holding the prior rate steady for three years.

Whitehead summarized her expected duties: she told the council that if Aurora receives a development application that exceeds one acre, the project will be required to obtain a construction stormwater permit under the state construction stormwater general permit, and she will review those permits and perform post‑construction monitoring where required. She said it was not yet clear how many additional permits Aurora will submit but that the county will assess workload and revisit fees when the contract comes up for renewal.

Whitehead also cited changes in state law she said affected local MS4 responsibilities; she referenced recent state legislative changes that altered the local permitting scope.

Council members confirmed planning and zoning support for the amendment and noted the agreement had been discussed during budget hearings. The council approved the interlocal amendment and said they would reassess after one year.

Why it matters: the MS4 interlocal agreement addresses stormwater permit review and post‑construction compliance for developments that can affect water quality. Assigning the county coordinator to handle construction permits over one acre creates a central review responsibility and clarifies where Aurora developers should apply.

Formal action: council approved the one‑year interlocal amendment and planning and zoning’s renewed agreement with Aurora by voice vote; the motion included a plan to reassess after a year.
