The Towns of Marshfield, Duxbury, and Scituate, located along the southern coastline of Massachusetts, are prone to recurring storm impacts, particularly storm surge. Recognizing that predicted sea level rise and more frequent extreme events will affect their communities, they engaged Kleinfelder to conduct a climate change vulnerability assessment and economic analysis of varied adaptation action plans.
The Kleinfelder team created GIS models to develop inundation maps for the 25-, 50-, and 75-year time horizons, using both sea level rise only and sea level rise and storm surge combined. These projections were combined with existing GIS data to determine the most at-risk assets within the towns’ jurisdictions. Recommended adaptation strategies were developed based on those results.
