Lake Tahoe BMP Information

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.
  • Conveyance: Stormwater runoff from impervious surfaces must be captured and conveyed to infiltration systems.
  • Sediment Trap: 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 Living with Fire website for more information.
  • 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.
