The Town of Falmouth engaged Acorn to help with stormwater drainage issues in the Route 1 Commercial District, specifically in Catchment #5, which impacts Webes Brook. This brook has shown stress due to development, and the 2013 Stormwater Management Plan identified it as high-risk for impairment.
The main issue is with the quantity of water, particularly the peak flowrate from Catchment #5. To tackle this, Acorn facilitated meetings with landowners and conducted a thorough assessment of existing conditions. We gathered data from various sources, including as-built plans, the Town’s GIS system, and inspection and maintenance documentation. Using HydroCAD, we then modeled the existing conditions and calibrated the model with observations from recent stormwater events. They explored the impact of adding storage solutions at multiple locations within the catchment, which showed potential in reducing peak flowrates and alleviating stress on Webes Brook.
Acorn presented these findings to the Town and is preparing a detailed Memo summarizing the options for improving stormwater management within Catchment #5. This proactive approach aims to enhance stormwater management and protect Webes Brook.
