Erosion Control

Erosion Control
The below booklet contains standard plans and procedures sufficient for typical residential building construction. It is not intended to address all circumstances.

Since our streets and storm sewers are conduits for draining stormwater it is important to keep sediment and debris on the lots rather than tracked or eroded onto streets.

Our primary objective is to eliminate or reduce the amount of sediments and other pollutants leaving a residential home construction site. To accomplish this goal, steps and procedures called Best Management Practices (BMPs) are undertaken. When properly implemented, these erosion and sediment controls are very effective.

The subdivision in which you are building may already have an overall Stormwater Pollution Prevention Plan (SWPPP) and Minnesota Pollution Control Agency (MPCA) permit. That permit remains in effect until all the lots are developed. BMPs related to that permit and plan are in place and should not be removed or compromised. You will need to submit a Notice of Termination/Permit Modification form to the MPCA if you are not the subdivision developer, or working for the subdivision developer.

The grading/erosion control permit holder and the building permit holder are responsible for ensuring that adequate BMPs are in place on the individual lot, catch basins and functioning until the project is completed. A project is defined as completed only when 70 percent of the lot has been re-vegetated. When terminating your MPCA permit you must supply the new property owner with the MPCA New Homeowner Fact Sheet. The MPCA New Homeowner Fact Sheet is available at City's Public Works Department at 344 West Main Street Marshall, MN 56258.

There will be situations where side or rear lot line protection may not be required. For example two houses under construction on adjacent lots where the surface drainage runs away from the other lot. Given this scenario, it is not the intention to require perimeter protection between the two lots.

When reviewing the standards presented in this publication and considering implementation on your construction project, keep in mind the intent of the standard is "to prevent erosion and to minimize sediments from leaving the lot." Failure to do so can result in damage to adjacent property, damage to the City's storm sewer system, as well as contributing to the pollution of stormwater ponds and the Redwood River.

If any questions or concerns arise, please feel free to contact the Assistant City Engineer at 507-537-6773. We are committed to helping all of those involved with the implementation of these construction procedures.
