The Shoreline Change (Beach) Special Area Management Plan

Shorelines are constantly changing, and Rhode Island coastal communities are increasingly experiencing the impacts. Storm waves can erode beaches and flood developed areas, while rising sea levels subsume land. Communities are asking how they can protect people and property, as well as vital infrastructure such as drinking water supplies, utilities, and roadways.

Review of Adaptation Strategies (PDF)

The Rhode Island Coastal Resources Management Council, in coordination with the University of Rhode Island, has prepared a plan to help find solutions these problems, which are threatening communities in many areas along the state’s coast. The Beach SAMP aims to improve the coastal resiliency of cities and towns throughout Rhode Island to the threats of erosion and flooding caused by storm events or sea level rise. Using up-to-date research and expertise from a wide range of public and private sectors, the Beach SAMP will help inform state and local policy and planning initiatives. Part of this partnership includes the maintenance of the Beach SAMP web site by Rhode Island Sea Grant.

STORMTOOLSSTORMTOOLS is a method to illustrate and display storm inundation, with and without sea level rise, for different types of storms that could occur along Rhode Island’s coast line. The mapping application is available in two forms, Beginner and Advanced.



STORMTOOLS for Beginners is a one-map stop for all residents of Rhode Island to better understand their risk from coastal inundation.  This map allows you to enter an address in Rhode Island, and get answers to 3 questions about your property:

  1. Is my property vulnerable to STORM SURGE?;
  2. How DEEP will the water be on my property during a 100-year (1% chance) coastal storm?; and
  3. Will projected SEA LEVEL RISE affect my property?

Advanced STORMTOOLS provides a series of maps that illustrate what coastal flooding could look like in the future under different storm scenarios. It enables Rhode Island’s municipal officials and decision makers to better understand their risk from coastal inundation.

These maps provide information on flooding impacts from storms and sea level rise, show the extent and depth at any given point for nuisance floods (1,2,3,5, and 10 year recurrence intervals) and the 25, 50, 100, and 500 year storm scenarios at the 95% confidence interval.

About the STORMTOOLS data:

STORMTOOLS is accessed online through ArcGIS.com and can be used by anyone – there is no need to download any software. However if you are interested in downloading the actual shape files, they are available on RIGIS.

STORMTOOLS is intended to illustrate the predicted level of inundation due to storm surge and sea level rise.  For the latest estimated relative sea level change projections Click here to go to the Sea Level Change Curve Calculator by the US Army Corps of Engineers.
