We have a multi-faceted approach to nitrogen management in Connecticut that addresses land use issues, agricultural production, and water quality.
Extension faculty from the Center for Land Use Education and Research (CLEAR) are working on several applied research projects in support of better nitrogen (N) management. They are collaborating with the University of Rhode Island and EPA to create an online tool, “N-Sink,” to track the movement of N in coastal watersheds (Highlights, 2020). In a project funded by the Long Island Sound Study (LISS), they are using cutting-edge high resolution land cover data to explore the relationship of land use to N export for the over 4,300 small watershed basins in Connecticut. Finally, the CLEAR geospatial team is part of another LISS study, led by Dr. Ashley Helton of the
Department of Natural Resources and the Environment, that is looking at “legacy” N loadings that are derived from past land uses that are no longer apparent but that continue to export N to our waters.
Rich Meinert is working with three farms on developing accurate as applied maps for farm applications. Current as applied maps provided by GPS systems are inaccurate on smaller New England farms. Our small irregularly shaped fields require spreaders to negotiate tight turns. Current generation software does not calculate the differences in as applied rates between the inside and the outside of a turn. Preliminary measurements using equipment on one of the farms has resulted in a 30% decrease in application rate on the outside of a turn versus the inside of the turn.
Another challenge in our smaller fields is overlap. Current spreaders have a fixed operating width. They throw lime, fertilizer, or manure with a set amount of force, across a fixed width, or they spray manure, or pesticides from a single point or a set of nozzles with a certain pressure and spray pattern, like a paint sprayer. Having a fixed application width and a varying field shape inevitably results in overlap. Certain sprayers can shut off nozzles to prevent overlap, but fertilizer and manure spreaders cannot vary their discharge. This research is currently collecting data to develop a computer algorithm to show where the nutrients are actually going so that future nutrient applications can target areas of fields that need it, and avoid areas that have had excess nutrients applied previously.
Extension educators from the Center for Land Use Education and Research (CLEAR) and their partners have developed an online tool that helps land owners and land use decision makers better understand the direct connection between their land and nitrogen (N) pollution in coastal waters.
The tool, called “N-Sink,” is the result of a multi-year collaboration of CLEAR with the University of Rhode Island Coastal Institute and the EPA Atlantic Coastal Environmental Sciences Division Laboratory in Narragansett, Rhode Island.
Nitrogen (N) pollution is a big threat to water quality, especially in coastal areas like Long Island Sound. Excess nutrients like N can fuel algal blooms that rob the waters of oxygen, directly harm marine life, and damage habitat. As a result, much attention has been paid to N pollution by the scientific community, including the development of many models designed to explore the transport and fate of N in our coastal watersheds. Most of these models focus on N “loadings,” i.e., estimating the amount of N being put into the system from sources like agricultural and lawn practices, septic systems, and atmospheric deposition from acid rain. Thus the focus is on what the total load of N is to the receiving water body, and what the impacts to that water body might be.
N-Sink uses a different approach that shifts the focus to the land within the watershed, rather than the receiving waters. The end result is a series of maps that help to provide specific geographic focus on which areas in the watershed are at the most risk for sending N to the coast (see maps, right). To do this, N-Sink uses particle tracking technology in concert with stream network data that includes information on nitrogen “sinks”—areas in the landscape that help to remove N from the system, like wetlands, riparian areas, lakes, and ponds. Depending on the sinks that it encounters along its journey to the coast, a unit of N could have very different fates, and thus very different impacts on water quality. For instance, a pound of N in one area of the watershed could be transported almost entirely to the coast, while another pound of N, applied just a short distance away, could take a different pathway through the stream network that results in the removal of a significant amount of N via sinks.
“One contribution of N-Sink is that it focuses on critical sink areas like wetlands and riparian corridors, which will hopefully lead to intensified efforts to protect or even restore these areas,”
says Extension Educator Chet Arnold. “Also, since the geographic specificity of N-Sink ties any location in the watershed to its likelihood of contributing N pollution, we think it can be useful both for land use planners when determining future uses, and land owners when discussing management practices on land already in use.”
The CLEAR team has created a state-of-the-art interactive N-Sink application where you can explore the maps for the entire Long Island Sound coast of Connecticut.

CEDAS ISSUES ‘BEST PRACTICES IN LAND USE AND ECONOMIC DEVELOPMENT’ ACCREDITATION TO TWENTY-FOUR CONNECTICUT COMMUNITIES
The Connecticut Economic Development Association (CEDAS) is proud to announce that it has certified twenty-four Connecticut cities and towns as exemplifying best practices in land use and economic development. These twenty-four communities subjected themselves to a rigorous application review process that required documentation of their procedures for development projects and consideration of their economic development strategy.
This is CEDAS’s first year accrediting communities. The program, presented by sponsors Eversource and UI, was conceived as a way to recognize communities that are committed to doing economic development and at the same time, to raise the bar for excellence in the entire state. Applications were submitted from across Connecticut, with towns and cities showcasing the policies that create efficient economic development processes, target strategic business growth, and implement planning and zoning practices that thoughtfully plan for future population and community-specific needs. The 2019 application cycle opened in June and concluded on September 15th. The expectation is that other communities will follow their lead and take part in next year’s accreditation process.
This year’s certified communities are the: Town of Bethel, Town of Bolton, City of Bridgeport, Town of Brookfield, Town of Canton, City of Groton, Town of Ellington, Town of Fairfield, Town of Farmington, City of Hartford, Town of Madison, Town of Manchester, City of Milford, City of New Haven, Town of New Milford, Town of Newtown, Town of North Haven, Town of North Stonington, City of Norwich, Town of Portland, Town of Groton, Town of West Hartford, Town of Windham, and Town of Windsor.
Awards will be presented to communities receiving 2019 ‘Best Practices in Economic Development and Land Use Planning’ accreditation at the CEDAS’ Annual Meeting on October 23rd in Bridgeport, Connecticut. This event will celebrate successful applicants, present updates on CEDAS’ activities and growth, and continue the conversation on how ‘Best Practices’ communities can showcase this designation as models for growth and as partners for future investment. To secure tickets please visit www.cedas.org.
“In order for our state to be successful at economic development, we need all levels working together and at the top of their game – local, regional, and state. The communities we are recognizing have shown a commitment to economic development and exemplify that Connecticut is open for business,” said Garrett Sheehan, this year’s President of CEDAS and CEO of the Greater New Haven Chamber of Commerce. This program was never intended to be a competition, but rather a way to raise our collective standards. I strongly encourage all Connecticut communities to adopt these best practices and apply for next year’s certification.”
“This program was an excellent way to recognize the existing efforts of many communities and provide great examples of best practices for others. It was an amazing collaboration and I was pleased to work on the program” said Laura Brown, UConn Extension and CEDAS Board Member.
The Best Practices program was created as a partnership with Eversource, UI, Pullman & Comley, and STV/DPM to present this accreditation as a catalyst for economic development in Connecticut. Collaborating partners include UConn Extension, the Connecticut Chapter of the American Planning Association, and the Connecticut Economic Resource Center. Connecticut can celebrate in the fact that it has many communities that are committed to economic development and doing it right. Staff, volunteers, and elected officials spent hours putting together their applications. Officials and volunteers organizing their community’s application also used this process as a chance to review their current policies and plans for business and community growth and as an opportunity to receive recommendations for updates and future improvements. According to one applicant “We applied because we do have best practices, but the internal and external dialogues don’t recognize that. This designation helps change the dialogue, and gives us direction on improvements.” The Program review committee also identified initiatives and programs that represent model approaches. These existing programs will be organized to create a resource library of examples for other communities looking for successful examples.
CEDAS is a non-profit association of economic development professionals. The organization is managed by an all-volunteer board. CEDAS works closely with the Department of Economic and Community Development (DECD) and the Connecticut Economic Resource Center (CERC) to foster economic growth in the state. CEDAS focuses networking and training opportunities for its membership.
The Connecticut Economic Development Association congratulates those communities receiving the 2019 ‘Best Practices in Economic Development and Land Use’ accreditation and aims to highlight their success and contributions to promoting Connecticut as a home for future business and community growth.

Sea Level Affecting Marsh Migration (SLAMM) is a mathematical model developed by NOAA that uses digital elevation data and other information to simulate potential impacts of long-term sea level rise on wetlands and shorelines. CT DEEP recently completed a project to run the SLAMM model for the Connecticut coastline, to better understand how Connecticut’s 21 largest coastal marshes and coastal area roads may respond to sea level rise (SLR).
The model results have been turned into a new viewer on CT ECO, and there will be a webinar on October 16 to review the results (see below).
