The Cape Cod Commission is working with all 15 Cape towns, including the Town of Truro, to examine vulnerabilities in the roadway network and identify solutions. With funding support from the U.S. Economic Development Administration (EDA) and the Massachusetts Municipal Vulnerability Preparedness (MVP) program, the Commission has contracted with the Woods Hole Group (WHG) to conduct a vulnerability assessment of roadway segments, bridges, and culverts due to flooding from the combined effects of sea level rise and storm surge.

WHG will employ the state-of-the-art Massachusetts Coast Flood Risk Model (MC FRM) to identify vulnerable road segments under different sea level rise scenarios and time scales. One output from this work is a projection of the probability and extent of flooding at the present, 2030, 2050, and 2070.

High Priority Road Segments

Truro Low Lying Roads High Priority Segments

Adaptation Strategies Analysis

Following the workshop last spring, town staff identified two priority road segments to carry forward into the design process for this project. Adaptation solutions for each of the prioritized road segments include analysis of four alternative strategies: gray infrastructure, green infrastructure, a hybrid approach, and managed retreat (abandonment or relocation). 

Conceptual Design Options

The conceptual design plans for each prioritized road segment and their associated adaptation solutions are available in these documents:
