Planning board clarifies site-plan details: batteries, failover and equipment protections

Board members examined site-plan notes for a telecommunications site that listed battery-backed primary failover systems, a generator for extended outages, and steel covers intended to protect equipment from falling ice.

Tim (rookie member) said the wireless carriers had referenced battery-backed systems as the "primary failover" and that Chelten-type batteries for about 12 to 36 hours of operation were cited in the materials. The transcript records discussion about whether carriers would rely on the battery failover and manually restart equipment or bring a portable generator for extended outages.

Members also questioned a line in the draft minutes describing ice and protection. The engineer and board clarified that steel covers are intended to deflect falling ice and protect the equipment cabinet, not to fully enclose the steel structure. "Ice will fall from the tower and will be deflected by the steel cover," a board member summarized during the discussion and members agreed to reword the minute so it matches the engineer’s description.

For field verification, the board asked the applicant to stake the proposed 50-by-50 area showing the tower location and utility cabinet before the continued hearing; members said they could make staking a condition of approval if the board moves to approve the site plan at a future hearing.
