ecology
The study of the total pattern of relationships between a community or organisms and its the environment.
drainage
The process of controlling, collecting, transporting, and disposing of excess water.
baffle
A partial obstruction against flow, in a duct or pipe.
improved land
Land on which buildings have not yet been constructed, but which contains utilities and streets.
manhole
A hole through which a person can enter a sewer, pipe, conduit, and so on for inspection, repair, or maintenance.
land coverage
The ratio of the area covered by buildings to the total lot area, expressed as percentage.
degree day (dd)
The amount by which the average outdoor temperature at a particular location is below 65 degrees Fahrenheit for one day. Degree days may also be summed and stated for a month or year.
gazebo
A belvedere of viewing place.
setback
The minimum distance from the property line into which a structure may not extend.
storm sewer
A sewer for carrying away surface water, as oppose to sanitary sewage.
survey
The process of determining location, form, and boundaries of a parcel of land by measurement, computation, and drawing.
handicapped parking
One or more spaces designated for the physically handicapped persons, requiring special design and dimensions.
court
A space, open and unobstructed to the sky, located at or above grade, and bounded on three or more sides by the walls of the building.
plat
A plan of a city or subdivision, showing the boundaries of individual properties.
off-street parking
Space provided for vehicular parking separate from the dedicated street right-of-way.
water table
The level below which the subsoil is completely saturated with water. Also called the groundwater level.
alley
Any public way r thoroughfare 10 to 16 feet in width which has been dedicated or deeded to the pubic for public use.
spot elevation
The elevation of a specified point on the ground or on a structure.
linear pattern
A pattern of land use which develops along a line, such as a highway or river.
grading
Removing and/or adding in order to bring the ground surface to a specified elevation or profile. Also called earthwork.
albedo
Reflectivity measured as the relative permeability of a surface to radiant energy flowing in either direction.
barrier-free
Having no environmental barriers, thereby permitting free access and circulation by the handicapped.
buildable area
The net ground area of a lot which can be covered by a building after required setbacks and other zoning limitations have been accounted for.
lot
The smallest identifiable parcel of land in a city.
altitude
The angle which the sun makes with the horizon.
lot line
The boundary line of a lot.
swale
A graded flow path used in open drainage systems.
azimuth
A horizontal angle measured clockwise from north or south.
slope
Inclination or slant, especially of the ground surface.
encroachment
The extension of a building into the property of another.
grade separation
The intersection of two roads at different levels so that vehicles may move from one road to the other without crossing the stream of traffic. Also called interchange.
dew point
The temperature of air which the water contained in the air begins to condense and form dew. It is therefore the temperature at which the air is at 100% relative humidity.
flood plain
The land surrounding a flowing stream over which water spreads when a flood occurs.
groundwater level
The level below which the subsoil is completely saturated with water. Also called the water table.
subsoil
The soil layer beneath the topsoil.
environmental impact statement
A statement, often required by a governmental body, which assess the environmental impact of a proposed development.
evergreen
Trees having green leaves throughout the year, as opposed to deciduous.
latitude
The number of degrees north or south of the equator of a point on the earth’s surface.
drain tile
Clay pipe, usually with open joints, used to convey water away from a footing or to disperse liquid in a septic tank field.
frontage
The length of a lot line along a street or public way.
