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. Ms,. Heidi Griffin April 28, 2'000 Planning Board Page 2 W,a hope that this inforrnation satisfies the concerns addressed by the Board. If you have any further immieldiate questi:ons, you may contact Mr. Ric�k Hayden at our office. Otherwise, we will be glad to furtheir dISCUSS this rnatter at the, next Planning Board meeting.
