ANSWER

1. (a) $22,000

(b) $58,000

2. Yes. 70 db(A) measured at the accepted standard L10 (18 hour) scale.

3. Yes. Traffic counts in Vanderlin Drive show a 10% increase
in traffic volume between 1992 and 1994 when the respective
noise measurements were taken. Studies have shown that
mounding and vegetation can have some impact on noise
reduction, hence the treatments undertaken in Vanderlin
Drive.
