TOPSHAM, MAINE

FB Environmental completed a Baseline Climate Change Vulnerability Assessment for the Town of Topsham, Maine to evaluate how climate change may affect infrastructure, public systems, and community assets. The assessment reviewed current conditions and future risks related to extreme precipitation, flooding, sea level rise, increasing temperatures, drought, and shifting ecosystems, and identified locations across town where roads, bridges, neighborhoods, and utilities are most vulnerable.

​

The project combined spatial data analysis, document review, and local input to understand existing challenges and emerging climate hazards. Findings highlight vulnerabilities to flooding along key road corridors, stormwater and heat island concerns in developed areas, groundwater rise in neighborhoods, and drought risks in rural areas relying on private wells.

​

This assessment provides the Town with a foundation for climate action planning by identifying priority areas of concern and supporting future resilience strategies, infrastructure investments, and long-term adaptation planning.
