** “Bounding Property Line” shall be interpreted
as being at the near side of any street, alley, stream, or other permanently
dedicated open space from the noise source when such open space exists
between the property line of the noise source and adjacent property.
When no such open space exists, the common line between two parcels
of property shall be interpreted as the bounding property line.

(-7db.)

When noise is present for not more than the following, add (+10db):
|
1/2 minute in any 1/2 hour period
|
1 minute in any 1 hour period
|
10 minutes in any 2 hour period
