Basic Land Use Tools for Resiliency
SHARE

Overview

Zoning allows a community to target regulations to areas at risk from damage due to human actions, sea-level rise, storm surge, and flooding.  It may be used to avoid development in hazardous areas; reduce community storm impacts; conserve natural protective features; and control development densities to reduce impacts and facilitate recovery.  

Without adequate zoning or other basic tools like site plan and subdivision review, development and redevelopment can continue in ways that place people, property, and critical infrastructure at risk from climate-induced sea-level rise, storm damage, and flooding.
