The Cape Cod Commission is working with all 15 Cape towns, including the Town of Barnstable, 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.

Launch Viewer in Separate Window

The Low Lying Roads Data Viewer is an interactive tool which allows the user to view the data outputs of the low lying roads analysis in a visual map format. The Data Viewer also allows the user to provide comments directly on the map to register observations about flooding or erosion issues in town.

To use the Data Viewer, click on the link above and navigate around the map, clicking data layers on or off using the Layers tab. To add comments or observations about flooding or erosion, follow the steps below:

  1. Make sure the "Comment" Layer you want to use is TURNED ON in the Layers TAB
  2. Choose the Editor button and pick the appropriate issue (Flooding or Erosion)
  3. Click on the area you would like to comment on
  4. Fill out the form
  5. Submit!

High Priority Road Segments

Barnstable 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:

 Bridge Street (by town landing)

 Ocean Street (from Aselton Park to Nantucket Street)


The Cape Cod Commission is accepting comments on proposed conceptual designs for prioritized road segments identified in the Low Lying Roads Project. To provide comments, visit the form linked below.
