The Coast Guard is amenable to working with the Town as part of that effort.

Technical requirements and practical solutions are the next focus
The next step is to obtain the Coast Guard’s technical requirements and evaluate practical alternatives that can meet its minimum aid-to-navigation requirements together with the nearshore and offshore safety needs identified by local mariners. Engineering requirements, cost, responsibility and long-term maintenance remain to be clarified as the collaborative work continues.
