Description
This program, administered by the Executive Office of Energy and Environmental Affairs (EEA), funds the replacement or removal of undersized, perched, or degraded culverts in areas of high ecological value across Massachusetts. The goal is to promote the use of improved structural and environmental design standards, enhance flood resiliency, and restore stream connectivity and habitat. Applications are submitted through the streamlined Environment & Climate One Stop (ECO One Stop) portal, allowing eligible entities to apply for multiple climate and environmental grants in a single process. Projects must intend to meet the Massachusetts Stream Crossing Standards and demonstrate ecological, community, and climate resilience benefits.
