During the recent Nantucket Select Board meeting on April 2, 2025, discussions centered on critical stormwater management strategies aimed at enhancing the island's resilience to flooding and improving water quality in local harbors. The board highlighted the importance of implementing green infrastructure solutions, which could significantly reduce costs associated with stormwater management and improve environmental outcomes.

One of the key topics was the ongoing efforts to divert stormwater from higher elevations, such as Academy Hill, to lower areas like Lily Pond. This approach not only minimizes the need for costly pumping but also utilizes natural landscapes to manage water flow more effectively. The board noted that property owners who incorporate green infrastructure on their land could see a reduction of up to 50% in their stormwater fees, a strategy already adopted by other towns.

Additionally, the board addressed the urgent need for repairs to the town's aging stormwater infrastructure. Recent inspections revealed significant deterioration, particularly in areas like the Town Pier and Brant Pointe, where sinkholes and collapsing pipes have become a concern. Emergency repairs are planned to address these issues, with a phased approach to further repairs over the coming years.

In a proactive move, the town is launching a stormwater sampling program in collaboration with the Nantucket Land and Water Council. This initiative will involve installing composite samplers and flow meters at five outfalls discharging stormwater into the harbor. The goal is to establish a baseline understanding of nutrient and bacteria levels in the water, which have not been previously monitored. This data will be crucial for addressing water quality issues and could help trace the sources of bacterial contamination, potentially leading to improved public health outcomes.

The meeting also touched on the restoration of a constructed wetland at Washington Street Extension, which was designed to treat stormwater before it enters the harbor. This forward-thinking project, initiated in the early 2000s, exemplifies the town's commitment to sustainable water management practices.

As Nantucket continues to grapple with the impacts of climate change and urban development, these discussions underscore the Select Board's dedication to enhancing the island's infrastructure and protecting its natural resources for future generations. The community can expect to see tangible improvements in stormwater management and water quality as these initiatives move forward.
