Special Flood Hazard Area
A special flood hazard area is where 100-year floods and damaging waves can be expected. Flood maps are produced by FEMA and are continually updated.
Flood Plain
An area of low-lying ground adjacent to a river, formed mainly of river sediments, and subject to flooding.
Acre
One acre = 43,560 square feet.
Nonconforming Use
In zoning law, a nonconforming use is a use of a property that doesn’t conform to current zoning laws, but was conforming at the time it was established. It is, therefore, generally allowed to continue.
Effluent
Effluent is wastewater, treated or untreated, that flows out of a treatment plant or sewer and is released into surface waters.
Aquifer
A body of saturated rock through which water can easily move.
Buildable Land
The portion of the site where construction can occur, including land voluntarily set aside for no construction.
Ecosystem
A complex set of interconnected relationships among the living organisms of a specific place that form a system, including plants, trees, animals, fish, birds, microorganisms, water, soil, and humans.
EPA Act of 1992
The Energy Policy Act of 1992 requires that all toilets use no more than 1.6 gallons of water per flush and all urinals use no more than 1.0 gallons per flush.
Greenfield
A site that has never been built on or developed for human use.
Impervious
The characteristic of a material preventing the penetration of liquids and/or gasses.
Potable
Water that is suitable for drinking.
Manhole
A manhole is an access point for servicing underground utilities. Manholes are located at junctions placed every 150 feet.
If a road has a 3% slope, what is the change in elevation after driving 100 feet up the road?

Permaculture
Short for “permanent agriculture,“ permaculture is a sustainable environmental design approach focused on the synergistic relationships of agriculture and people.
Food Forest
In permaculture, a food forest is a garden of diverse edible species designed to work together in a small space to maximize productivity.
Plant Hardiness Zone
A geographic area defined by what types of plants can grow there, based on their ability to withstand the low temperatures of the region. The USDA first defined the categories and now publishes plant hardiness maps.
Overlay
Zoning ordinances may include overlay districts or zones that require a higher level of performance or other considerations for the design and use of a site. They are special zones that lay overtop of base zones. Examples include riparian or flood overlays, historic , and slope restrictions.
Fire Partition
Minimum Partition Rating = 1 HR
Fire Barrier
Fire rating = 1 Hr or more, offers more protection than a fire partition
Fire Wall
Fire rating is 2-4 hrs, used to separate a single structure into separate construction types or to provide for allowable area increases by creating what amounts to separate buildings even though they are attached.
Smoke Barrier
Partition rating = 1 HR, continuous vertical or horizontal membrane that is designed and constructed to restrict movement of smoke
