This erosion control planning sheet is a necessary attachment for all land use/building permit
applications in shoreland and residential zoning districts. Because of the impact of uncontrolled storm
water runoff from construction sites to surface water, the Kandiyohi County Zoning Office requires that an
erosion control plan be submitted with applications for permits in shoreland and residential areas. In order
to protect surface water quality, a comprehensive and detailed plan is needed that ensures the control of
storm water runoff.
If you feel that an erosion control plan is not necessary because of the nature of your lot and/or the
limited scope of your project (e.g. small deck or moved in yard shed), please provide a brief
explanation for the Zoning Administrator to consider.________________________________________

Below is a list of erosion and sediment control methods and practices. Please read the list carefully.
Circle the numbers of the corresponding erosion control practices that are appropriate and will be
implemented at your project site.
1. Maintain existing vegetation whenever possible and minimize the area of disturbance. Retain and
protect trees to enhance future landscaping efforts and to reduce raindrop impact. (Vegetation is the
best and most cost-effective erosion control practice.) Stake and flag areas before construction.
2. Install all erosion and sediment control practices prior to any upland soil disturbing activities.
3. Divert run-on around the site, if practical (avoids treating clean water).
4. Phase construction activities to minimize the areas disturbed at one time. This will also allow
completed areas to be stabilized and re-vegetated before disturbing adjacent sites.
5. Maintain and protect all natural waterways. Retain at least a 20-foot wide strip of natural vegetation
along all waterways to filter out sediment and other pollutants.
6. Minimize the use of impervious surfaces such as roofs, driveways, parking lots, and roads.
Disconnect impervious surfaces whenever possible (e.g. direct downspouts to lawn areas, not
driveways.)
7. Use rock rip-rap at both the outlet and inlet ends of culverts to prevent scour erosion and use energy
dissipaters at the outlet ends (e.g. plunge pools).
8. Limit construction equipment to designated areas to control soil compaction. Keep equipment away
from existing trees, future sewage treatment areas, and infiltration basins.
9. Install silt fence and/or fiber log products on the down-slope perimeter of all disturbed areas
according to the attached installation instructions prior to any soil disturbing activities (including
clearing and grubbing). Protect sensitive areas such as wetlands, drainage swales and shoreland
areas with silt fences or fiber logs.
10. Install rock dam checks, bale checks, or fiber logs in areas of concentrated flow.
11. Use temporary slope drains or rock chutes to move water down steep slopes.
12. Construct sediment basins and/or infiltration basins for areas with a large (5-10 acres or more)
contributing watershed.
13. Line waterways with erosion control blankets.
14. Protect storm drain inlets with a combination of silt fencing, fiber logs, straw bales, and rock dams.
15. Cover any stockpiled soil with plastic or use a temporary seed mix.
16. Use stockpiled topsoil as earthen berms to direct runoff or to create temporary sediment basins.
