Subject: 	FW: Decibel dBA levels at closest property line for rooftop equipment

Hi Nell:

Please see the attached information on the Hyatt Hotel Old Port.

I believe that this should address the ordinance concerns.

Please advise if this will suffice.

Greg,  I have taken the rated dBA for each piece of equipment and
calculated the dBA levels at the closest property line.  As you can see,
all equipment falls under the 55 to 60 dBA constraints of the B‑3 zone.
