St. Joseph County Stormwater
Construction Stormwater General Permit/MS4 Regulations

Plan Submission Contacts for
St. Joseph County  


Throughout St. Joseph County, several people have been established by local municipalities for overseeing the sediment control of construction projects that will disturb more than 1 acre of soil.  



  • Within the city limits of Mishawaka, including Bethel College, MS4/CSGP SWP3's are to be submitted to the Mishawaka Planning Department, ATTN: Melissa McGuire (574-258-7113).     



  • In the remaining areas of the county that are incorporated, but that are either too small to have a designated oversight person, or just elect not to have one at this time, the CSGP SWP3’s are to be submitted to the St. Joseph County Soil and Water Conservation District, ATTN: Sarah Longenecker (574-936-2024 Ext. 4).  Mrs. Longenecker will also be over seeing the SWP3’s for projects being conducted by an MS4 entity (i.e. City of South Bend, City of Mishawaka).


If you are still uncertain as to who the appropriate overseeing entity is for your project, contact Sarah Longenecker, St. Joseph County SWCD at 574-936-2024 Ext. 4 or the St. Joseph County Engineering Dept., at 574-235-9626.

Did you know...

Currently stormwater runoff is not treated before entering our rivers and streams. We must do our part to prevent pollution from entering our waterways and protect aquatic life. 


Simple activities that can be done to prevent stormwater runoff pollution are:

  • Never dump anything down storm drains.

  • Use lawn fertilizers sparingly.

  • Direct downspouts away from paved surfaces.

  • Consider a rain garden to capture runoff.

  • Pick up pet waste.

  • Compost your yard waste.

  • Check cars for leaks.

  • Wash your car at a car wash or in your lawn.

  • Have your septic tank pumped and inspected regularly.
