Stabilizing Construction Entrance

Stabilizing Construction Entrance

Construction entrances are stabilized to reduce the amount of sediment transported onto paved roads, by vehicles or equipment, by constructing a stabilized pad of quarry spalls at entrances to sites.

Diagram: Stablilizing Construction Entrances

  • Construction entrances shall be stabilized wherever traffic will be leaving a construction site and traveling on paved roads or other paved areas within 1000 feet of the site. 
  • Use and maintain gravel construction entrances where truck traffic is frequent. This will reduce soil compaction and limit tracking of sediment onto streets.

Limitations

  • The entrance is only as good as the materials used to construct it.
  • Must use clean pit run for single driveway.

Maintenance Requirements

  • If the entrance is not preventing sediment from being tracked onto pavement, then alternative measures to keep the streets free of sediment shall be used.
  • Any sediment that is tracked onto pavement shall be removed by shoveling, scraping or street sweeping. Sediment collected by sweeping shall be removed and stored onsite.
  • Any quarry spalls that are loosened from the pad, which end up on the roadway, shall be removed immediately.
  • Upon project completion and site stabilization, all construction accesses intended as permanent access for maintenance shall be permanently stabilized.
