A chiller at Hamilton Stage exceeds noise limits to the extent that it will require the construction of a sound wall at a cost of almost $32,000.

The Redevelopment Agency last month awarded a contract to build a sound wall to KDP Developers, Inc., for $31,970, the lowest among three bids. Other bids were $38,000 by K&D Contractors and $42,341 by Gingerelli Brothers.

Noise readings confirmed that the level was above acceptable limits during the day and night. The city ordinance allows a maximum level of no more than 65 dBA during the day and 50 dBA at nighttime. Daytime and nighttime limits are exceeded at 344 Hamilton St. and night time limits are exceeded in all measure locations.

Tests were conducted at four points:
* 344 Hamilton, corner of property — 68.1 dBA
* In street, 50 feet away — 65.4 dBA
* 359 Hamilton St., 87 feet — 61.9 dBA
* 339 Hamilton St., 110 feet — 61.9 dBA

“Calculations show the presence of a barrier alone falls short of achieving nighttime compliance under all load conditions at the property boundary of 344 Hamilton, adjacent to Hamilton Stage and closest property to the chiller equipment.” Ambient conditions were measured between 48-50 dBA.
