Susan Loomis of Eastview Drive told the council during public comment that the draft Bristol Innovation Park design parameters do not adequately protect nearby neighborhoods from industrial noise and that the DPUD's assumptions fail to account for sound traveling over the Saint Joe River.
"The design parameters for the Bristol Innovation Park plan need to be improved with respect to noise," Loomis said, arguing the DPUD allows assumptions that could permit noisy operations adjacent to residential areas. She urged the council to adopt an industrial-noise standard that takes attenuation over water into account.
Council members and staff responded that the DPUD and overlay ordinance establish different decibel limits depending on adjacency: where industrial zoning abuts residential property the ordinance sets 60 dB by day and 55 dB at night, while industrial-to-industrial adjacencies can be higher (the transcript cited 80 dB in those circumstances). Staff emphasized that, before building permits are issued, applicants must supply noise studies tied to actual uses and that a site-plan review committee will evaluate buffering and mitigation measures.
Town counsel and staff also noted the current rezoning request is being made by landowners and that specific operational details (for example, whether a data center or other noisy use would locate there) are not being decided by the council until site applications and use details are submitted. Staff said that when a use is proposed and a noise study is required, the committee and planning staff — with council input if needed — can require additional buffering or design changes.
Next steps: the council did not change the DPUD at the meeting. Residents were told there will be an opportunity for site-plan review and for the council or planning staff to press for noise mitigation once specific uses and studies are submitted.
