Rhode Island Updates Coastal Construction Setback Requirements
New standards reflect updated erosion data and sea level rise projections
PROVIDENCE – The Rhode Island Coastal Resources Management Council confirmed this week that it has approved updated setback requirements for new coastal construction, incorporating updated erosion rate data and sea level rise projections that officials say better reflect current understanding of long term coastal change along the state’s shoreline.
The updated setback requirements
Council spokesperson Beatrice Fontaine-Achterberg said the updated requirements establish greater minimum setback distances for new construction in erosion prone areas, based on updated historical erosion rate analysis incorporating several additional years of shoreline monitoring data since the previous setback standards were established.
Fontaine-Achterberg said the council’s technical staff conducted detailed shoreline change analysis at numerous points along the coastline, finding that erosion rates at several locations have proceeded somewhat faster than the previous setback standards had assumed, directly informing the increased setback distances in the updated requirements.
Property owner and developer response
Coastal property owner and developer representatives expressed concern about the updated requirements’ effect on buildable lot area for new construction, particularly on already narrow coastal lots where increased setback requirements could meaningfully constrain construction options compared to the previous, less restrictive standards.
Several property rights advocates specifically questioned whether the updated erosion projections adequately account for potential future beach nourishment or other erosion mitigation measures that might affect actual long term erosion rates at specific locations differently than the general coastline wide analysis suggests.
Coastal science perspective
Coastal geologists who contributed to the underlying erosion analysis defended the updated projections as reflecting the best currently available science, while acknowledging genuine uncertainty remains in long term erosion projection given the complex, sometimes locally variable factors affecting actual shoreline change at any specific location.
Researchers specifically noted that setback requirements represent a precautionary approach appropriate given this genuine scientific uncertainty, arguing that erring toward greater setback distances provides more robust protection against underestimating actual future erosion risk compared to setting standards based on more optimistic erosion projections.
Public safety and infrastructure considerations
Council officials emphasized that setback requirements serve public safety purposes beyond simply protecting individual property investments, noting that construction too close to actively eroding shorelines can create genuine safety hazards and, when structures eventually require emergency protection or removal, can generate significant public cost and environmental disruption.
Fontaine-Achterberg said the updated requirements aim to reduce future instances of exactly this kind of costly, disruptive emergency response by ensuring new construction maintains adequate distance from actively eroding shoreline areas from the outset.
What happens next
The updated setback requirements take effect for new construction permit applications, with the council planning to continue periodic review of erosion rate data to assess whether further setback adjustments become necessary as coastal conditions continue evolving.
Further information on Rhode Island coastal management policy is available through the Coastal Resources Management Council and the University of Rhode Island Coastal Resources Center.
Historical erosion data context
The council’s updated analysis incorporated shoreline position data extending back several decades, allowing researchers to identify genuine long term erosion trends distinct from shorter term fluctuation that can result from individual storm events rather than reflecting sustained underlying shoreline change patterns.
Fontaine-Achterberg said this longer historical dataset provides considerably more statistical confidence in the updated erosion rate projections compared to analysis based on more limited historical monitoring data available during previous setback standard development processes.
Variance and appeal process
The updated requirements maintain an existing variance process allowing property owners to request case specific setback modifications where genuine site specific circumstances might warrant deviation from the standard requirement, though council officials note variance approval requires demonstrating specific technical justification rather than simply general hardship.
Looking ahead
Council officials say continued monitoring of erosion trends will remain essential as coastal conditions continue evolving statewide.
Regional comparison
Coastal policy researchers note that updated setback standards reflecting current erosion science have become increasingly common among Atlantic coast states facing comparable shoreline change challenges.
The council says updated erosion monitoring data will be published as part of its ongoing periodic shoreline review process.
Stakeholder engagement continues
Council officials say they will continue engaging with property owners and coastal scientists as erosion monitoring continues.
