- Best management practice fact sheet 10: Dry SwaleSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2020)A wet swale is an engineered, BMP arranged in a straight line that is designed to reduce stormwater pollution. It consists of a shallow, gently sloping channel with broad, vegetated, side slopes and slow flows. Wet swales typically stay wet because the bottom of the swale is below the water table. This is done to encourage the growth of wetland vegetation.
- Best management practice fact sheet 11: Wet SwaleSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2020)A dry swale is a shallow, gently sloping channel with broad, vegetated side slopes. Water flow is slowed by a series of check dams. A dry swale provides temporary storage, filtration, and infiltration of stormwater runoff. they should remain dry during periods of no rainfall. It is a BMP designed to reduce pollution runoff reduction and pollutant removal and is part of a site's stormwater treatment practice.
- Best management practice fact sheet 12: Filtering practicesSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2020)A stormwater filtering practice treats stormwater runoff by passing it through and engineered filter media consisting of either sand, gravel, organic matter, and/or a proprietary manufactured product, collecting it in an underdrain, and then discharging the effluent to a stormwater conveyance system.
- Best management practice fact sheet 15: Extended detention pondsSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2020)Extended detention ponds (EDs) are dry detention ponds that provide 12 to 24 hours of runoff storage during peak runoff events. Releases from the ED ponds are controlled by an outlet structure. During a storm event, as the discharge restriction is reached, water backs up into the ED pond. The pool slows flow velocities and enables particulate pollutants to settle. Peak flows are also reduced.
- Best management practice fact sheet 1: Rooftop disconnectionSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2019)Discussion of rooftop disconnection and compost amended flow paths
- Best management practice fact sheet 2: Grass channelsSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2019)Discussion of grass channels as a storm water conveyance system
- Best management practice fact sheet 2: Sheet flow to open spaceSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2019)Discussion of Sheet flow to open space (SOS) drainage practices
- Best management practice fact sheet 5: Vegetated roofsSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2019)Discussion of vegetated roofs which reduces storm water runoff and pollution.
- Best management practice fact sheet 6: rainwater harvestingSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2019)Discussion of devices that intercept, divert, store, and release collected roof runoff from rainfall for later use as an alternative water supply
- Best management practice fact sheet 8: Infiltration practicesSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2019)Discussion of infiltration practices which provide temporary surface and/or subsurface storage, allowing infiltration of runoff into the soil.
- Best Management Practice Fact Sheet 9: BioretensionSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2019)A biorentention cel, or rain garden, is a best management practice (BMP) designed to treat stormwater runoffs from roofs, driveways, walkways, or lawns. Where it can be used, how it works, what it does, maintenance, performance, limitations, expected cost
- Best management practices fact sheet 4: Soil restorationSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2019)Discussion of soil restoration; the technique of using compost to amend soils to improve their porosity and nutrient retention. The restored soils are less compacted and can replicate runoff from forested areas.
- Constructed WetlandsSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2020-01)Constructed Wetlands are low cost and sustainable engineered best practice to reduce stormwater pollution.
- Permeable pavementSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2019)Permeable pavement on the top layer is efficient for storm water run off.
- Wet pondsSample, David J.; Fox, Laurie J.; Hendrix, Carol (Virginia Cooperative Extension, 2019)Ponds or lakes which provide treatment and storage of stormwater.
