The processes, lessons learned, and resources outlined in the framework are geared toward state departments of transportation (DOTs), metropolitan planning organizations (MPOs), and other agencies involved in planning, building, or maintaining the transportation system. It includes suggestions and examples applicable to a wide range of applications, from small qualitative studies to large, detailed, data-intensive analyses. The resources included in the framework will be added to and updated over time.

The team engaged with community members to determine the present hazards and vulnerabilities and identify resilient solutions.

The City of New Haven has installed 286 right-of-way bioswales throughout the city as part of a multifaceted approach to reducing flooding in the downtown area. Right-of-way bioswales are engineered planted areas that are located on sidewalks. They are designed to capture and infiltrate stormwater into the ground that would otherwise directly enter a storm drain. These bioswales were installed as the result of various partnerships and funding opportunities related to flood prevention, localized drainage solutions, combined sewer overflow mitigation, research, and traffic calming projects.

In 2019, the City of Norwalk secured a LIS Future Fund grant to install green infrastructure in the Webster Street Parking to reduce the impacts of stormwater on the Norwalk River and Harbor and mitigate local flooding of surrounding businesses through the installation of four different types of infiltration and bio-retention structures:
1) Underground infiltration systems.
2) Retention basins and curb inlet planters in eight different areas.
3) Porous pavement with storage in two areas.
4) Infiltration gutters and tree filters in two other areas.

Friends of the Bay installed two raingardens at the Western Waterfront, which was done in October 2021 with the help of volunteers.

The Hempstead Harbor Protection Committee and Village of Sea Cliff completed subwatershed improvements at Scudders Pond to address stormwater drainage problems impacting the water quality of the pond and Hempstead Harbor, highlighted as a priority in the 1998 Hempstead Harbor Water Quality Improvement Plan. The improvements included dredging the pond, installing a hydrodynamic separator to intercept sediment, removing invasive Phragmites australis and replacing with native plants, realigning the stream to reduce erosion, redirecting the stormwater from residences to the bioswale, creation of a biofilter wetland area, replacement of the weir between the upper and lower ponds and weir at Shore Road.

This comprehensive study and plan, funded through the National Fish and Wildlife Foundation, Long Island Sound Futures Fund, identifies initial strategies to maintain and enhance the local watershed resources of Crab Meadow. It is meant to be a land management tool to guide the implementation of best practices. The plan was developed in consultation with many partners and stakeholders.

Increased development and the historic construction of a dam on Sunken Meadow Creek in the 1950’s led to reduced tidal exchange, increased water levels in the creek, poor water quality, and the proliferation of invasive species. In 2008 a number of partners (NYS OPRHP, NOAA, NYSDEC, LISS, TNC, Save the Sound, USFWS, LI Botanical Society) came together to work to restore the degraded marsh habitat around Sunken Meadow Creek, increase tidal flow, improve aquatic organism passage, limit invasives, and improve water quality. A restoration feasibility study was completed in 2010. In 2012 Superstorm Sandy blew out the dam on Sunken Meadow Creek, naturally kick-starting restoration. Following Superstorm Sandy, the project partners were able to quickly capitalize on available funding and grants, due to their prior planning efforts. A bridge was built across the Creek where the dam blew out, salt marsh habitat was restored at three locations, green infrastructure was installed in one of the parking areas to capture and treat stormwater runoff, fish passage feasibility on the creek was investigated, and education and outreach was conducted to thousands of people. These projects were completed in 2019. Now, with funding through Long Island Sound Futures Fund, Audubon NY is leading a large-scale marsh restoration project at Sunken Meadow Creek to restore important high-marsh habitat for at risk species, like the Saltmarsh Sparrow, and to increase the resilience of the marsh in the face of rising sea levels. Audubon will be working to finalize the designs and secure permits over the next two years, with on-the-ground restoration expected in 2026.
