BMPs most commonly prescribed for residential properties include:
Pave dirt driveways, parking areas and roads
Compacted dirt areas routinely disturbed by vehicular traffic are notorious sediment sources, especially in the winter during snow removal activities. Compacted dirt areas shall be paved and the runoff captured and infiltrated or restored and blocked off to prevent future disturbance.
Install Parking Barriers
Parking barriers prevent future soil disturbance from vehicle traffic. They consist of large boulders, bollards, a fence and large established vegetation
Stormwater runoff from impervious surfaces must be captured and conveyed to infiltration systems
Driveway conveyance systems must have an accessible sediment trap installed prior to the infiltration system to facilitate maintenance.
Infiltrate stormwater runoff from impervious surfaces
Runoff from impervious surfaces such as roofs, driveways and walkways must be captured and infiltrated into the soil before it can leave the property. Gravel/rock infiltration systems or infiltration basins are common infiltration BMPs.
Stabilizing or retaining steep slopes and loose soils
Materials such as rock, wood and vegetation can help stabilize soils and prevent sediment from being transported offsite.
Maintain a 5 foot non-combustible perimeter around each structure
To be Fire Defensible Space (FDS) compliant, no combustible materials, such as pine needles, woodchips or woody vegetation, are permitted within 5 feet of any structure. Gravel and rock or irrigated herbaceous vegetation are acceptable alternatives. Visit the

Vegetating and mulching bare soils
Vegetation and mulch can help stabilize soils and prevent sediment from being transported offsite. Be sure to maintain defensible space by spacing vegetation and applying organic mulch, such as wood chips or pine needles, in discontinuous patches within the 5-30foot zone.
