FEMA’s National Resilience Guidance document is intended to help all individuals, communities, and organizations understand our nation’s vision for resilience, the key principles that must be applied to strengthen resilience, and the players and systems that contribute to resilience. It also outlines how to strengthen resilience by organizing and engaging people, incorporating resilience concepts into planning efforts, creating change through policies, prioritizing projects and programs, financing resilience efforts, and measuring and evaluating resilience. Finally, the NRG includes a Resilience Maturity Model that illustrates stages in the evolution of a community’s approach to resilience.

To better understand how Connecticut’s coastal area marshes and roads may respond to sea level rise (SLR), Sea Level Affecting Marshes Model (SLAMM) was applied to Connecticut’s shoreline by Warren Pinnacle Consulting, Inc. This viewer displays the model’s results for Connecticut’s 21 largest marshes and all coastal area roads. For marshes, SLAMM was run two hundred times using alternative model inputs for key model parameters, including various SLR scenarios, to produce probability based results of likely future marsh conditions. For roads, the model uses a single SLR scenario of about 4.2 feet by 2100 from the base year of 2002. The Sea Level Rise Effects on Roads and Marshes projects is a project between CT DEEP and UConn CLEAR.

The group includes federal, state, and town agency staff, researchers, nursery growers, educators, master gardeners, community members, and interested citizens.

The LINAP Embayment Water Exchange Study looked at how water exchange practices could affect the nitrogen impairments in embayments. A water exchange practice changes the amount, speed, or direction of water moving through an area. The results of the study show that water exchange techniques are not effective in large waterbodies like most of Long Island’s embayments. Often, the physical size of the water exchange practice is small compared to the large waterbodies to which they are applied, which means their impact is limited. Water exchange projects may be useful, however, for smaller Long Island waterbodies, where the volume of increased water exchange approaches the volume of the overall waterbody. The goal of the study was to provide communities with basic information on water exchange practices suitable for Long Island.

The Equitable Resilience Builder (ERB) is an application that supports communities in resilience planning with a focus on equity.
