Site Planning & Design 2 Flashcards
dew point
The temperature of air at 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.
bearing
In surveying, a direction stated in degrees, minutes, and seconds as an angular deviation east or west from due north or south.
way
A street, alley, or other thoroughfare or easement permanently established for passage of persons or vehicles.
exedra
A semicircular open area, with or without a roof, providing a continuous seat.
survey
The process of determining location, form, and boundaries of a parcel of land by measurement, computation, and drawing.
parterre
An ornamental garden arrangement.
runoff coefficient
The percentage of total rainfall which is not absorbed in the ground and, hence, runs off. It must be collected in a system of surface and subsurface drains.
invert
The lowest point of the inside of a drain, pipe, channel, or other liquid-carrying conduit.
bench
An excavated, level terrace in a slope used to collect running water.
plot
A parcel of land.
wind chill index
A fictitious temperature assigned to a combination of actual temperature and wind velocity which has the same physiological effect of still air at the wind chill index temperature. It is also known as the chill factor.
windbreak
Structures or plants which, because of their form and location, reduce wind velocities.
plat
A plan of a city or subdivision, showing the boundaries of individual properties.
block
A division of urban land, normally private property, which is surrounded by public streets, and which is officially established and recorded.
lot
The smallest identifiable parcel of land in a city.
granolith
Concrete used for paving which uses crushed granite as the coarse aggregate.
berm
A bank of earth, often piled up against a wall.
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.
degree day(dd)
The amount by which the average outdoor temperature at a particular location is below 65 degrees Farenheit for one day. Degree days may also be summed and stated for a month or year.
datum
A horizontal plane elevation used as a reference for other elevations in surveying and mapping.
