zero lot line
part of a zoning regulation’s setback requirements that allows a building to be constructed up to the property line with no setback

leaching field
subsurface wastewater disposal facilities used to remove contaminants and impurities from the liquid that emerges after anaerobic digestion in a septic tank
building height
distance from grade to the average height of the highest roof surface
Elements poorly affecting quality of automobile entrance to site
- adjacency to Arterial road
- poor angle to road
- near adjacent roads intersection with other road
Noise from a point source decreases by_____ as distance increases while noise from a linear source (highway) decreases at __________ meaning _______
- the square root of the distance increases
- linearly
- doubling a buildings distance from a highway will only reduce noise by a few decibels which is barely noticeable
Humidity comfort zone
30-60%
