Re Noise Issues
Dear Ms. ,Griffin-
Pursua,nt to a question from the Planning Boo aird' at the April 4, 2000 public hearing, Daidio
Designs has, investigated noise generation of the new miailroorni additio,n. Noise will primarily be
generated by two component : truck tragic and rooftop miechanicall eqUipment.
Truck Traffic., The, Eagle-Tr[bune is constructing the addition to install new [liserting equipment
so that they can meet the ad'verfising dernands, of the business community. There Mill be
rn ini rnAl increase in producti on capacity. No, increase crease in truck t raff ic to allin d', from the site is
anticipated,, nor WEI there be, a change in the time of day that trucks Mfl 2ccess, the site. As
stich, there wifi be, no increase or change in the noise levelgenerated by trucks due to,the
proposed addition.
Rooftop MechaNcal Equipment; Three new heating and coolling units will be installed on the
roof of the addition, Air is circulated through the units by fans, tl iat are enclosed in the unit
housings. We offer the following cond'itions, that will dramatically reduce sound generation.
* The sounid generated by the fans will be reduced because, they are enGtosed in meta[
housings-,
* The Units will be located over 200 feet from the property line. Under 110rM121 conditions,
the sound will be attenuated,
* A significant buffer of trees exists between the addition and the nearest adjacent
residential properties. The tirees will provide substantial noise buffer.
For these reasons, the increase in Solind generated by rooftop heating and Cooling equipment
will be nli'nirn,al or noon-existent.
