Stormwater Controls after Wildfire

Grade control structure
Rock Check Dams

After the Cerro Grande fire in 2000, and the Las Conchas fire in 2011, LANL installed many runoff-mitigation structures to slow the water and redirect it away from problem areas.

Rock Check Dams

Rock check dams reduce the velocity of concentrated stormwater flows and are an effective aid in trapping sediment particles by virtue of the ability to pond runoff.

Mulch

Wood mulch is an engineered erosion control material used to prevent wind erosion, rill formation, and promote revegetation.

Sediment Traps

Sediment traps reduce offsite sediment migration.
