Erosion & Sediment Control (Construction Storm Water)

In unincorporated Porter County, all land disturbing activities are governed by the Porter County Erosion & Sediment Control Standards, as presented in Section 7.15 of the UDO. Such standards help minimize soil erosion and prevent sediment-laden storm water runoff from leaving development sites.

Generally speaking, an Erosion & Sediment Control permit is required for all land disturbing activities conducted in unincorporated Porter County. Projects involving less than 10,000 SF of land disturbing activities do not require an Erosion & Sediment Control Permit , except when such sites are located within or immediately adjacent to: (a) storm sewer inlets, (b) ditches or streams, (c) wetlands. The Porter County Erosion & Sediment Control Standards do not apply to nursery, mineral extraction, or agricultural activities conducted as a permitted use.

Storm Water Management (Post-Construction Storm Water)

Unless specifically exempted, all land disturbing activities in unincorporated Porter County are also required to meet the Porter County Storm Water Management Standards, as presented in Section 7.28 of the UDO. Such standards address the increased storm water runoff rates, volumes, and pollutants loads that result from the land development process.

Generally speaking, all land disturbing activities conducted in unincorporated Porter County must comply with the Porter County Storm Water Management Standards. Projects involving additions or modifications to existing single-family homes or involving less than 10,000 SF of land disturbing activities, provided that such land disturbing activities are not part of a larger plan of development and that they do not create more than 1,000 SF of new impervious cover, are not regulated under the Porter County Storm Water Management Standards.
