The Green Infrastructure Specialist will help Hartford respond to threats of flooding while evaluating and advancing green infrastructure projects.
How Will Sea Level Rise-Driven Shifts in Wetland Vegetation Alter Ecosystem Services?
This project examines how sea level rise (SLR) induced shifts in vegetation will change ecosystem services provided by Long Island Sound (LIS) coastal wetlands. Specifically, the project will: 1) quantify the delivery of ecosystem services associated with dominant tidal wetland plant species of the LIS; 2) examine impacts of SLR and interactions; 3) forecast how shifts in dominant tidal wetland species will alter ecosystem service provision of LIS coastal wetlands; and 4) promote understanding of the complex interactions among SLR, coastal wetlands, and ecosystem services among diverse audiences in the LIS region.
Increasing Resilience and Reducing Risk Through Successful Application of Nature Based Coastal Infrastructure Practices in New England
Since the State of Connecticut has adopted regulations to limit further expansion of hard coastal protection structures (sea walls, revetments etc.) and to promote the use of “living shore line” approaches, tracking the effectiveness of demonstration sites is a priority activity. As a consequence of its geological setting and development history, the harbors of Connecticut require periodic maintenance dredging to ensure safe navigation.
Kent Land Trust – Creation of a Strategic Workplan to Identify Parcels Enhancing Climate Resilience
The Kent Land Trust was established in 1989 to preserve natural resources in Kent and surrounding areas through land protection, stewardship, public outreach, education, and research. The primary goal of their CIRCA Matching Fund project was to develop a more science-based climate-focused land acquisition and land management strategy. The new model strikes a balance between cultural, historic, and aesthetic considerations and natural resource criteria linked to climate resilience.

Led by researchers at Sacred Heart University, this project expands an existing living shoreline project at Stratford Point, Fairfield County, Connecticut. On-going coastal restoration efforts and research at the site consist of an artificial reef, smooth cordgrass (Spartina alterniflora) marsh, high marsh, coastal dune and upland woody/grassland mosaics.
University of Connecticut – Natural Resources Conservation Academy: Fostering Young Scientists in Connecticut Communities
The Natural Resources Conservation Academy’s mission is to provide transformative and authentic learning opportunities to diverse groups of high school students; stimulating critical thinking, creativity, decision-making, and appreciation of science application and nature while contributing to local environmental solutions. The NRCA directly educates high school students from throughout the state each year on climate change effects in Connecticut as well as solutions to climate change issues. All NRCA student conservation projects are conducted in both coastal and inland communities and a majority of projects address adaptation or mitigation solutions to climate change. Student conservation projects also often include an educational component, in which the student’s community will learn about the climate change issue that the student’s project is addressing and possible solutions. NRCA will advance the development of resilience and sustainability of coastal and inland communities that are vulnerable to the impacts of climate change.
Waterford Municipal Infrastructure Resilience Project
The Waterford Municipal Infrastructure Resilience Project is a two-part project that assesses the vulnerabilities of the town’s sewer pumps stations as well as an analysis of drainage at Gardiners Wood Road. The flooding Waterford has been receiving during recent storms has caused disruptions to multiple pump stations, demonstrating the need for repairs. The pump stations evaluated are on the border, or within areas noted as having a high probability of inundation under certain sea level rise scenarios.
Waves in Long Island Sound and Living Shorelines Site Suitability Tool: NOAA CREST project
The NOAA CREST project has significant wave heights for different return periods for all of Long Island Sound, measurements of waves in Old Saybrook and New Haven harbors, a review of design guidelines and tools for site assessment of living shorelines. This information is summarized in an online map viewer.
WestCOG – Regional CRS Program
Western Connecticut is extremely vulnerable to natural hazards. Many of its most critical assets including public safety, sanitation facilities, transportation corridors, employment centers, and affordable housing are located on or near the coast or the region’s many inland waterways. Using a CIRCA grant, WCOG is taking steps to create a regional CRS program and specifically assist four municipalities as they take on mitigation efforts to reduce the impacts of coastal and riverine flooding. WCOG is helping to provide cost savings by performing CRS activities and CRS municipal coordination at a regional scale.
