LEED EXAM

Site Assessment
Evaluation of above-ground (including facilites) and subsurface aharacteristics, including the geology and hydrology of the site
Remediation
The process of cleaning up a contaminated site by physical, chemical or biological means. Typically applied to contaminated soil and groundwater
Constructed Wetland
designed to simulate natural wetland functions. Esessentially treatment systems that remove contaminants from wastewaters.
Impervious Surfaces
Promote runoff, instead of infiltration into the subsurface
Stormwater Runoff
All percipitation waters that leave a project site
Total Phosphorous (TP)
Found in stormwater, originates from fertilizer application.
Total Suspended Solids
particles that are too small or light to be removed from stormwater via gravity
Infiltration Basins and Trenches

Basins-Ponds that can store large volumes of water.

Trenches-shalllower and function as a subsurface reservoir

Both need to drain within 72 hours to maintain aerobic conditions and to be available for the next storm event.

Porous Pavement and Permeable Sufaces
allow runoff to infiltrate into the subsurface
Vegitated Filter Strips and Grassed Swales

utilize vegetation to filter sediment and pollutants from stormwater.

Filtration Basins
remove sediment and pollutants from stormwater runoff using a filter media such as sand or gravel
Detention Ponds
capture stormwater runoff ad allow pollutants to drop out before release to a stormwater or water body
