The steep coastal bluffs at the site of the former Crescent Park and the adjacent shoreline rise 20 to 30 feet above the narrow beach. Erosion had carved out the lower third of the bluff in several areas and previous efforts to reduce erosion through traditional practices had failed. This work was part of a larger regional initiative to learn how living shorelines perform in New England.

SumCo Eco constructed a nature-based infrastructure solution for mitigation of the bluff erosion at Rose Larisa Park. In addition to erosion control, a biodegradable shoreline with plantings and an inter-tidal sill along the beach below the bluff was created, as well as a salt marsh for beach protection.
