Erosion Control Notes
Remove or strikeout notes that are not applicable to the site.
General Notes
- Construct and maintain erosion control measures in accordance with Wisconsin DNR and Dane County requirements.
- Install erosion control practices prior to initiating other land disturbing activities.
- Inspect erosion control measures weekly and after every rainfall event exceeding 0.5 inches within 24 hours. Repair to erosion control measures shall occur within 24 hours of inspection.
- Erosion control is the responsibility of the contractor or landowner until site is stabilized. Additional erosion control measures, as requested by regulatory agents or owner's engineer, shall be installed within 24 hours.
- Install tracking controls to prevent sediment from being tracked onto adjacent roadways. Sediment in the roadway shall be removed by street cleaning (not hydraulic flushing) before the end of each work day.
- Install inlet filters prior to construction or immediately after inlets are installed and maintained until site is stabilized. Remove accumulated sediment when it reaches 1/3 to 1/2 of the device depth.
- Divert channelized runoff from adjacent land around disturbed areas.
- Install perimeter control around stockpiles and stabilize stockpiles that will remain inactive for 7 days or longer.
- Temporarily stabilize disturbed areas that will remain inactive for 14 days.
- Permanently stabilize any portion of the site within 7 days of reaching final grade.
- Install and maintain a concrete washout. Chute washwater may not be dumped on the ground.
- De-watering shall conform to DNR Technical Standard 1061 and may not increase erosion.
- Remove accumulated sediment from ditch checks and stone weepers when it reaches 1/2 of the device height.
- Notify the Dane County Water Resources Engineering Department within 10 days of installing all erosion control practices and upon site stabilization.
- Remove all erosion control measures once all disturbed areas are vegetated.

Detailed construction schedule must include all elements of erosion control and stormwater management plan, consistent with dates from the soil loss calculation.
