Erosion Control 2008
Erosion & Sediment Control Plan: So you have a Natural Resources Management Permit (NRMP)
for your project, now what? Here are a few things to keep in mind BEFORE,
DURING AND AFTER the completion of your project! Please follow these steps
in order: A. Erosion & sediment control measures MUST BE IN PLACE
BEFORE any clearing or grading begins as stated by City Ordinance. B. Install temporary sediment/erosion controls such as;
silt fence, biorolls, mulch berms, filter logs, and/or erosion control
blankets/netting to contain sediment on your property and to keep it off
your neighbors’ property, surrounding streets, sidewalks and out
of the City of Apple Valley’s storm sewers. This is important to
keep our City ponds & lakes clean! C. Please call the Natural Resources Department at 952-953-2463
to schedule a time for an erosion control inspection prior to the start
of your project. We would like to make sure your controls are D. Now you are ready to begin your project! When grading
your property, REMEMBER to keep sediment off the street! Even temporary
placement of sod, mulch, rock, sediment etc. is prohibited from being
placed on the roadway. E. Routine erosion & sediment control inspections will take place on site and an inspection report will be provided to the Project Manager listed on the NRMP application. If erosion & sediment control corrections are not completed by the re-inspection date, the City will DISCONTINUE BUILDING INSPECTION SCHEDULING and/or issue a STOP WORK ORDER until corrections are completed. F. Sometimes there is a need for temporary stabilization
during a project. You may need to seed and/or mulch areas of loose, unstable
sediment that is not currently under construction for more than 7 days. G. Finish your project! Now is the time to install permanent
stabilization. Vegetation is the best and most cost-effective erosion
control practice. Make sure your property is vegetated within 30 days
of completed construction. The Minnesota Pollution Control Agency (MPCA) Permit Standards
for Maintenance & Inspection are as follows: 1. Inspect your project site every 7 days and within 24
hours after every ½ inch rain event to ensure the erosion &
sediment controls are working properly. If not, repair immediately. 2. Clean out silt fences when they are 1/3 full of sediment,
or replace with functional silt fences within 24 hours. 3. Maintain construction entrance and clean adjacent roads and/or sidewalks of any mud tracked onto them. Content updated on: 29-May-2008
