Term
Development Footprint
Definition
Area on the project site that has been impacted by any development activity. Hardscape, access roads, parking lots, non-building facilities and building structures are all included in the development footprint.
Term
Building Density
Definition
The floor area of the building divided by the total area of the site (square feet per acre)
Term
Site Area
Definition
Property Area
Term
Bioremediation
Definition
The use of microorganisms and vegetation to remove contaminants from water and soils
Term
CERCLA
Definition
Comprehensive Environmental Response, Compensation, and Liability Act - aka Superfund: Addresses abandoned or historical waste sites.
Term
Ex-Situ Remediation
Definition
The removal of contaminated soil and groundwater for off-site treatment. i.e. pump and treat.
Term
In-Situ remediation
Definition
Treatment of contaminated soil or ground water in place. i.e. injection wells, reactive trenches.
Term
RCRA
Definition
Resource Conservation and Recovery Act: Gives EPA authority to control hazardous waste from cradle to grave.
Term
Preferred Parking
Definition
parking spots closest to the main entrance or discounted parking passes.
Term
Building Footprint
Definition
Building area - does not include parking lots landscapes or non-building facilities
Term
Open Space Area
Definition
Defined by local zoning or Property area minus development footprint. Area must be vegetated and pervious. In Urban Areas open space includes pedestrian oriented hardscapes.
Term
Total suspended solids (TSS)
Definition
particles or flocs that are to small to be removed from storm water via gravity settling. Must be removed via filtration
Term
Albedo
Definition
Solar reflectance
Term
Emissivity
Definition
ratio of radiation emitted by a surface to the radiation emitted by a black body at the same temperature.
Term
Heat Island Effects
Definition
Warmer temperatures are experienced in urban landscapes compared to adjacent rural areas due to solar energy retention on constructed surfaces. (streets, sidewalks, parking lots, buildings all contribute)
Term
infrared emittance
Definition
number between 0 and 1 that indicates the ability of a material to shed infrared radiation. Most building materials (including glass) are opaque to this wavelength)
Term
Non- roof Impervious Surface
Definition
all surfaces on site with a perviousness less than 50%. Most asphalts.
Term
Open Grid Pavement
Definition
Pavement that is less than 50% impervious and has vegetation in open cells.
Term
(SRI) Solar reflectance index
Definition
measure of a materials ability to reject solar heat as shown by a small temperature rise. (black = 0 white = 100
Term
Angle of maximum Candela
Definition
direction in which the luminaire emits the greatest luminous intensity.
Term
Curfew hours
Definition
local hour of lighting restrictions or 10:00 pm by default.
Term
footcandle (fc)
Definition
is a unit of illuminance = one lumen of light falling on a one square foot area from a one candela light source at a distance of one foot.
Term
Light Pollution
Definition
waste light - light that produces glare, is directed upward or off-site.
Term
Outdoor Lighting Zone Definitions
Definition
LZ1 Dark - population densities less than 200 people per sq mile.
LZ2 Low 200-3000 people per sq mile
Lz3 Medium - 3000 people per sq mile
LZ4 High - 100,000 or more peaople per sq mile
Term
Drip Irrigation
Definition
high efficiency irrigation method where water is delivered at low pressures through buried mains and networks of perforated tubes.
Term
Graywater
Definition
untreated house waste water that has not come into contact with toilet waste. ( cloths washers, sinks showers etc. may vary state to state
Term
Landscape area
Definition
total site area minus building footprint, paved surfaces,water bodies etc.
Term
Micro-irrigation
Definition
involves irrigation systems with small sprinkler or drippers designed to apply small volumes of water
Term
Auquatic systems
Definition
use biological organisms to treat wastewater to advanced levels.
