Planning Ahead

Filed under: Video — Tags: , , , , , , , — Sheetflow @ 3:40 am

Planning ahead requires a different mindset to prevent problems rather than react when they happen.

On this project we are using the neighboring property for staging; all of the runoff drains into their constructed stormwater treatment swale.

Their stormwater discharges are regulated and any non-compliance issues could be attributed to the contractor’s use of this area.

Concrete Tiltup Project Runoff

Managing Construction Runoff on Concrete Tiltup Building Project- I shot this video to show ways to manage stormwater runoff when you have acres of concrete and asphalt. This was a bus maintenance building project that we completed about 8 years ago.

Clean Water Diversion

Unrolled Asphalt Berm Edge Clean Water Diversion – Here is another cool trick for keeping clean water out of your project. The contractor put down ATB (asphalt-treated base) and asphalt but didn’t roll (compact) the edge, which left a 3 or 4 inch berm. Clean rain water was kept on the asphalt rather than flowing off into the dirt shoulder and disturbed areas.

This Stormwater Pollution Prevention Plan (SWPPP) template for geotechnical exploration will save time when planning for any type of boring, drilling and potholing operations.

Construction Stormwater General Permit

Construction Stormwater General Permit

Construction site operators are required to be covered by a Construction Stormwater General Permit if they are engaged in clearing, grading, and excavating activities that disturb one or more acres and discharge stormwater to surface waters of the state. Smaller sites may also require coverage if they are part of a larger common plan of development that will ultimately disturb one acre or more. Operators of regulated construction sites are required to:

  • Develop stormwater pollution prevention plans.
  • Implement sediment, erosion, and pollution prevention control measures.
  • Obtain coverage under this permit.
