This section highlights various CLEAR activities. While an effort is made to note important events, research results and new tools, not everything CLEAR is involved in makes it to the News section. Past articles are provided to help gain a better understanding of the Center and its past endeavors.
CLEAR is blogging! We hope our blog will be useful in keeping you up-to-date on our latest research projects, training classes, workshops, webinars, publications, and anything else we feel like talking about. Below are some recent postings to our blog. Click an article you'd like to read or go directly to our blog page for a complete list of CLEAR-related news at clear.uconn.edu/blog.
01/11 – Riparian Areas and Agricultural Lands
Two new additions to the Connecticut’s Changing Landscape (CCL) Project have been added to the Center website. The CCL tracks changes to the state’s land cover over time, beginning in 1985 and running to 2006 (an update to 2010 is planned for this spring). In addition to the basic land cover change and CLEAR’s forest fragmentation analysis, the Center has added studies on land cover change in riparian (streamside) corridors, and over prime and important agricultural soils. An extremely brief summary of some of the highlights of the research follows. Readers interested in these studies are encouraged to visit the project websites, where research summaries and data, maps and charts are available.
Riparian corridors are known to be environmentally important areas critical to stream stability, pollutant removal, and both aquatic and terrestrial wildlife habitat. These areas are sometimes known as “buffers,” but are not to be confused with the regulatory review zones overseen by local land use commissions. CLEAR looked at land cover change during the 21-year project period for corridors 100 feet and 300 feet to either side of Connecticut’s streams, as determined by the state hydrography (waterways) data layer.
During the 1985-2006 period new development totaled about 5,100 acres in the 100-foot corridor, and about 19,000 acres in the 300-foot corridor. During that period, the percentage change in new development appears to have occurred at a slower rate in the 100-foot corridor than the 300-foot corridor, with both being slower than the rate for the entire state. At the town level, the amount of development in riparian areas was less than that for the overall town, but was also seen to vary closely with the overall town average. More can be found at: clear.uconn.edu/projects/riparian.
The Agricultural Fields and Soils study looks at land cover change over areas designated by the USDA Natural Resources Conservation Service (NRCS) to have prime or important farmland soils (“ag soils”). The CCL project’s major land cover categories include developed land, forest, turf/grass, and agricultural fields (derived from satellite imagery).
During the 21-year study period Connecticut lost approximately 31,000 acres of agricultural field overlying ag soils. Forest was by far the most common land cover on ag soils throughout the period, but by 2006 the developed land cover category had replaced the agricultural field category as the second-most common land cover on ag soils. As might be expected, important ag soil areas had more of the agricultural fields land cover category than the state as a whole. However, ag soil areas also had more development, more turf/grass, and less forest than the state overall. This might also be expected, since many soils well suited for agriculture, being relatively flat and well-drained, are also well-suited for development. More can be found at: clear.uconn.edu/projects/ag.
Working at Local, State, National and Cyberspace Levels
CLEAR's Geospatial Training Program (GTP) is actually much more than its name implies, working on a wide range of projects involving geospatial analysis and tool development, as well as developing and delivering training. All of this is primarily done by CLEAR's Cary Chadwick and Emily Wilson, who not only do their own projects but also provide ongoing support to CLEAR's other programs. As we like to say, the line outside their office is long. Here are some things that GTP is doing.
One of GTP's core functions is to develop and run training programs on geographic information systems (GIS), global positioning systems (GPS), and, increasingly, a wide range of technologies that can be described as "web mapping" techniques. The audience for these classes, which are frequently sold out, includes private sector professionals, academics, agency staff, nonprofit organization members, and of course CLEAR's main audience of community staff and commissioners. The GTP Training Schedule page is one of the most frequently accessed parts of the CLEAR website.
In collaboration with CLEAR's National NEMO Network, the GTP is also providing national training to members of the USDA National Water Program, a network that includes researchers, extension professionals, and other people at Land Grant and Sea Grant universities across the country. GTP conducts training sessions on online mapping techniques at the annual water program national conference and at specially scheduled regional workshops. To date, the team has been to South Carolina, California, Hawaii, Maine, West Virginia, Rhode Island Massachusetts, and New Hampshire.
On the tool development front, GTP has increasingly moved to online mapping tools. These tools, as opposed to desktop tools that require specialized expertise, are typically accessible to users at all levels of geospatial expertise. While there have been web tools on the CLEAR site for some time, including NEMO's Online Community Resource Inventory and the Connecticut's Changing Landscape site, the culmination of this work to date has been the creation of Connecticut Environmental Conditions Online, or "CT ECO." CT ECO was developed as a full partnership with the CT Department of Energy and Environmental Protection (CT DEEP). CT ECO uses advanced web mapping technology to provide local, state and federal agencies, and the general public with convenient access to the most up-to-date and complete natural resource information available statewide. Included is information and maps on water resources, topography, soils, protected areas, vegetation and much more, as well as the latest statewide high resolution aerial photos. CT ECO is at: www.cteco.uconn.edu.
As noted, GTP also conducts analysis and mapping in support of CLEAR's other programs. GTP, for instance, analyzes the land cover data produced by the Connecticut's Changing Landscape project, and creates the statistics, maps and websites needed to get that information out to the public. Occasionally, GTP will do an analysis at the town or watershed level, funding and time permitting. For instance, GTP and NEMO collaborated with the Connecticut Office of Policy and Management and the Central Naugatuck Region Council of Governments on a study of the planning technique known as a "buildout analysis." That study was focused primarily on a regional analyses and its implications for feasibility of conducting a statewide buildout (see nemo.uconn.edu/publications/about_buildouts.pdf). In contrast, a more recent project with the Town of Kent was conducted to provide information to the town as it develops revisions to its Plan of Conservation and Development. This project was taken on due to Kent's unusual soils-based zoning, and also broke new technological ground in that the data on building locations used in the analysis was provided by local volunteers via Google Earth.
GTP is not only its own program, but in many ways the glue that holds the many CLEAR programs together.
CLEAR would like to welcome the Community and Natural Resource Planning (CNP) Program to its family of partners. This new organization evolved out of the Green Valley Institute (GVI) which conducted land use education and outreach in the 35 towns of The Last Green Valley National Heritage Corridor since 1999. CNP will expand GVI's mission—improving the knowledge base from which land use and natural resource decisions are made—to reach a larger audience. The new format and collaborations will address community and natural resource planning issues throughout the entire state of Connecticut.
In partnership with the Connecticut Environmental Review Team and the Eastern Connecticut Resource Conservation and Development Area, CNP is conducting a series of land use workshops this year. In the fall of 2011, CNP conducted two series of four workshops each in conjunction with the Central CT Regional Planning Agency and the CT River Estuary Regional Planning Agency. This spring CNP will present two additional workshop series in conjunction with the Northwestern CT Council of Governments, the Litchfield Hills Council of Elected Officials and the Southeastern CT Council of Governments.
Each RPA conducted a brief online survey to assess the educational needs of the land use decision-makers in their region. As a result, the fall workshop series addressed the following issues:
Other CLEAR partner organizations, including CT NEMO, are participating by providing expertise on low impact development and other topics of interest.
CNP's staff includes Susan Westa, Associate Extension Educator who specializes in land use planning and policy and Paula Stahl, Assistant Extension Educator, licensed Landscape Architect and community finance specialist. They bring together a wealth of information and experience addressing a wide range of issues from community planning and design to economic development. Other CNP staff and organizational partnerships provide expertise in natural resource protection. Holly Drinkuth, CNP Natural Resource Program Coordinator also serves as the Director of Education and Outreach Programs for The Nature Conservancy in Connecticut, focusing on the benefits of healthy natural systems for communities. She currently works with CLEAR's Extension Forestry Program to provide information and support to Connecticut woodland owners, managers and community land use decision makers. CNP's work program will continue to evolve over the next year as it works with different communities and identifies educational needs of land use decision-makers throughout the state.

CLEAR came out with a number of publications in 2011 that may be worth a look:
The Connecticut's Changing Landscape (CCL) project is in the midst of expanding its geographic range and extending the time period covered by the study. The project is funded by the federal/state Long Island Sound Study, which uses CCL land cover change data to help track Long Island Sound conditions and trends. CLEAR is in the final stages of adding the portions of New York that drain to the Sound (which includes most of Westchester County and the northern shore of Long Island) to the CCL database for the 1985 – 2006 period. Maps and information for the newly expanded study area will be made available this spring on the web using cutting-edge internet mapping technology. Basic land cover, impervious cover, and riparian (streamside) cover change will all be included. Following quickly on the heels of the NY addition will be an update of the CCL using 2010 imagery, thus creating a nationally unique database charting 25 years (1985-2010) of change.
We hope our blog will be useful in keeping you up-to-date on our latest research projects, training classes, workshops, webinars, publications, and anything else we feel like talking about! Check out our new blog at clear.uconn.edu/blog.
12/10 - NEMO Turns 20!
The Nonpoint Education for Municipal Officials (NEMO) Program turns 20 in 2011. When it was first developed in 1991, NEMO’s focus on land use planning and better site design as the principal strategies to protect water resources was considered heretical, and its use of geospatial technology for outreach was unique. Twenty years later, “impervious surfaces” has entered the general lexicon (well, at least in our circles…) and GIS and remote sensing imagery are a part of everyday life. So, the world has changed, and of course so has NEMO. The program’s first decade was spent largely on helping local officials to understand the land use/water resource connection. And, although we will never lose our focus on land use planning, our second decade has been increasingly about helping communities embrace low impact development (LID). The future of NEMO seems very likely to focus on working in urban communities, as well as continuing its work with as many Connecticut municipalities as we can serve. There is much work to be done, and we’re glad that new NEMO Director Mike Dietz is here to lead the charge!

The Land Use Academy is soldiering on, despite the loss of state support and the retirement/departure of two of its CLEAR-based instructors. With partial support from our parent College of Agriculture and Natural Resources, CLEAR was able to hire Bruce Hyde, an experienced Connecticut land use planner, to keep the Academy doors open. Our partnership with CT Office and Policy and Management, Office of Responsible Growth continues. At present, we are conducting two full-day basic training courses per year, and are working on development of new courses, including one on affordable housing. The basic training has been revamped and is much more interactive than in years past. The new edition was tested out successfully at the November training, held at Central Connecticut State University (CCSU) in partnership with the CCSU Center for Public Policy and Social Research. 77 commissioners from 39 communities attended. Many thanks to our major partners, the Connecticut Bar Association Planning and Zoning section and our sister CLEAR program the Green Valley Institute, for their essential contributions of instructional expertise.

CLEAR’s National NEMO Network, a coalition of program in 30 states modeled after the Connecticut NEMO program, held its seventh national conference, NEMO University 7 (a.k.a. U7), in Portland, Maine Sept. 29 – Oct. 1. The conference was very well attended with over 100 registrants from 24 states, representing many diverse organizations and national networks. The two primary leaders of NEMO programs, Sea Grant and Extension, both piggy-backed additional meetings on the conference. Conference sessions focused on urban low impact development retrofits, local climate change adaptations, hybrid approaches to land use planning, and innovative approaches to supporting local land use officials.

CLEAR’s Geospatial Training Program (GTP) has suffered a partial loss of staff power, but is filling up its dance card with a new national training program funded by the USDA Water Program. The training focuses on the use of “mashups,” a combination of GIS and internet technology that allows anyone to easily post geographically-specific information via the use of web browsers such as Google Maps and Google Earth. The applications for research, outreach, monitoring and evaluation are virtually endless. As a result of the USDA grant, in between our Connecticut trainings GTP faculty have been busy traipsing all over North America training Land Grant and Sea Grant audiences on “Mashup Madness”.
For more information contact: Cary Chadwick, 860-345-5216. email@example.com.
The Center is rolling out a series of one-hour webinars that will cover a wide range of land use planning, land cover research, natural resource protection and geospatial technology topics. Beginning in February, 2011 we plan to do one webinar a month. (They’re free!)
The complete schedule and additional information can be found in the Webinars section of the CLEAR website. GO TO WEBINARS.
The Center, along with MAGIC (UConn’s Map and Geographic Information Center) was recently successful at gaining membership to AmericaView, a nationwide program that focuses on satellite remote sensing data and technologies in support of applied research, K-16 education, workforce development and technology transfer. A new website, ctview.org, will soon be completed to promote the access and use of remote sensing imagery in Connecticut. Currently there are 37 states participating in the AmericaView program.

Researchers at The University of Connecticut Center for Land use Education and Research (CLEAR) have just started a project to estimate lake water clarity based on Landsat satellite imagery. The process utilizes existing Secchi Disk transparency data (a circular disk attached to a line that is lowered into the water where a depth measurement is taken when the disk is no longer visible) and correlates this data with the reflectance characteristics of water pixels from Landsat to derive estimated water clarity, an indicator of water quality. Since it is cost prohibited to sample every sizable lake in Connecticut on a regular basis, the results of this project will provide us with the ability to systematically assess and examine lake water clarity for all lakes larger than 5 – 10 acres in surface area in Connecticut for a single date. Since Landsat satellite imagery are available beginning in 1972, the project will derive a multi-temporal set of lake water clarity estimates based on available Secchi Disk transparency and Landsat image data. Results of the project will be available on the CLEAR website in early 2011. Funding for this project is provided by the Connecticut Institute of Water Resources. For more information on this project, contact James Hurd at: email@example.com.
The American Society of Photogrammetry and Remote Sensing (ASPRS) have selected CLEAR Director Dr. Daniel Civco to be the 2010 recipient of the SAIC Estes Memorial Teaching Award at their annual conference held in San Diego, CA during the last week of April. This award, inaugurated in 2003, is named after Professor Jack Estes and is presented annually as recognition for individual achievement in the promotion of remote sensing and geographic information systems (GIS) technology and applications through educational efforts.
The first impervious cover TMDL (total maximum daily load) water regulation in the country is being implemented in the Eagleville Brook watershed in Mansfield, which includes much of the University of Connecticut (UConn) main campus. The response of the University and the town will focus on reducing the amount and impacts of stormwater runoff from impervious surfaces, which magnify, concentrate and channel pollutants into the brook. Project partners include CLEAR, CT DEP, the Town of Mansfield, the UConn Office of Environmental Policy, the Center for Watershed Protection and Horsley-Witten Group.
The field assessment portion of the project is almost complete. However, there has already been considerable progress on the ground (literally). UConn’s new twin pervious parking lots—one of porous asphalt and one of porous concrete —both allow rainfall to infiltrate directly into the ground through their surfaces, rather than generate runoff.
To channel Hartford’s own Mark Twain, reports of the death of CLEAR’s Land Use Academy, our basic training for new and continuing land use commissioners, are greatly exaggerated. While it’s true that the Academy lost its state funding last year to the state budget axe, we are hanging in there with a reduced schedule of one training this spring (May) and hope to have at least one more this fall. We are the in process of hiring a Land Use Educator to help put the Academy back on its feet, and to determine what can be done given the fiscal realities. Check out the Academy website at clear.uconn.edu/lua for updated Academy information.
CLEAR’s research team has just received a grant to use remotely-sensed data to track the health of Connecticut’s lakes. Satellite-derived data will be used to track lake water clarity, which has long been used by the scientific community as a key indicator of lake quality. The results will provide a cost-effective way to assess the state’s historical record of water clarity, identify change in water clarity in Connecticut lakes, and provide a methodology for continued assessment into the future. The grant is from the Connecticut Institute of Water Resources, part of a national network of 54 state water institutes that promote federal/state partnerships in water resources research and information transfer.
CLEAR's CT NEMO Program has produced a new publication on low impact development, Developing a Sustainable Community, that provides step-by-step guidelines for community leaders interested in implementing practices that help to reduce the impact of development on water resources. The booklet goes over 14 separate recommended site planning and design practices, each with real-life examples, illustrations, and most important, specific information on which plans, regulations and procedures need to be changed to implement them. The booklet is featured on the CT NEMO website (Publications section) right next to another recent NEMO tour de force, the About Buildouts booklet. View both booklets at nemo.uconn.edu/tools/publications.htm

12/09 - CT DEP and UConn Launch New Website with Digital Maps and Data on State’s Environment and Natural Resources
12/09 - CT DEP and UConn Launch New Website with Digital Maps and Data on State’s Environment and Natural Resources
The Connecticut Department of Environmental Protection (DEP) and the University of Connecticut Center for Land Use Education and Research (CLEAR) today launched a new website, Connecticut Environmental Conditions Online (CT ECO) that includes the latest and most accessible online maps and tools for viewing Connecticut’s environmental and natural resource information.
The new CT ECO website, www.cteco.uconn.edu, includes environmental and natural resource information for Connecticut such as protected open space, farmland soils, wetland soils, aquifer protection areas, water quality classifications, and drainage basins. Each can be viewed separately or in conjunction with other environmental and natural resource information. In addition, CT ECO includes several sets of high resolution imagery.
The University of Connecticut Center for Land Use Education and Research (CLEAR) is pleased to announce that the results of our statewide forest fragmentation analysis are now up on the CLEAR website: clear.uconn.edu/projects/landscape/forestfrag. About 60% of the state is classified as “forested,” i.e., covered with trees (as determined by our Connecticut’s Changing Landscape project). However, tree cover alone is not a reliable indicator of the functional health of forested ecosystems, which are greatly impacted by proximity to non-forested areas. By applying CLEAR’s forest fragmentation model to our land cover data, we can get a feel for these issues. For instance, from 1985-2006, the amount of “core” forest decreased by about 264 square miles; this includes conversion both to non-forest, and to the other (impacted) forest classes. The analysis results are available as statewide, town level, and watershed level maps, data tables, and downloadable data. Take a look!
CLEAR’s National NEMO Network has recently launched the Low Impact Development (LID) Atlas, a sophisticated website that is intended to show LID practices from around the country in a unique, interactive way. LID refers to a number of stormwater management practices, like grass swales, rain gardens, permeable pavements and green roofs that reduce runoff and help to protect water resources from the impacts of nonpoint source pollution. The new Atlas is a “mashup,” using Google Maps in combination with local data to create a searchable map that covers the entire country. The Atlas was developed by a partnership of the Connecticut and California NEMO programs, and is coordinated by the National NEMO Network “Hub” at CLEAR. The NEMO Network is now comprised of 32 programs in 30 states, all adapted after UConn’s original NEMO program. The most advanced feature of the Atlas is that all 32 NEMO programs and their partners can enter data, photos and links for LID practices in their own state, and have them immediately appear on the national site. Thus, the hope is that within a year’s time the national map will be festooned with the many-colored markers that mark the spot of an LID practice. “We’re hoping for at least 500 entries by the end of the year,” says Dave Dickson, NEMO Network coordinator. He adds that “this is an excellent example of the power of the Network to create unique educational products. Not many organizations could pull off something like this, and we did it with a minimal budget, just using the collective abilities of our network members.”
Chances are that you’re familiar with Google Earth and Google Maps. But did you know that these and other “earth browser” technologies can be used in combination with geospatial technologies to allow researchers, outreach professionals and others to share their data, maps and images over the web? This combination of techniques is commonly called a “mashup,” a term borrowed from the early days of hip-hop music when existing recordings and sound effects were “mashed” together to form a new creation. Mashup technology holds tremendous promise for broad-based dissemination of a wide variety of research and other information. Basically, any information with a geographic location can be displayed via an earth browser, including data, photos and links to websites and documents. A prominent example is the CT NEMO Low Impact Development (LID) Inventory, a searchable website that uses Google Maps to display information about LID sites across the state. A National LID Atlas, where any of the 32 NEMO programs around the country can create their own entries, just debuted this summer. Three CLEAR programs, the Geospatial Technology Program (GTP), the CT NEMO Program and the National NEMO Network, have collaborated to develop mashup training for colleagues in the state and the region. The prototype of the one-day workshop was tested in 2007 with colleagues from the National NEMO, USDA, NGTEN, Land Grant and NOAA Sea Grant networks, and has been fine-tuned in the intervening time. An advanced mashup class for Connecticut professionals was conducted in the spring by GTP, and a Northeast Region workshop for Land Grant and Sea Grant staff was held at the UConn Groton campus this past June. The workshop was a big success, and another is planned for Portsmouth, New Hampshire in October. “Mashup technology is relatively easy to learn, even if you’re not a GIS expert, and it’s so flexible that it can be used for a whole range of applications,” says Cary Chadwick, GTP’s principal mashup trainer. CLEAR hopes to obtain funding to continue these workshops, both instate, regionally and even nationally. For more information, contact Cary Chadwick at: email@example.com.
The Association of Public Land Grant Universities (APLU) has selected CLEAR Associate Director Chet Arnold to receive the Excellence in Extension award in the Northeast Region. The award is presented annually to an individual who has strived throughout his/her career to achieve benchmarks reflective of excellence in extension educational programming. Chet is being recognized for his work in co-founding and running the CT NEMO program, the National NEMO Network and CLEAR. He is the first recipient of this award from UConn or even New England.
In July, CT NEMO began field work on a project to improve Eagleville Brook watershed, which is located in Mansfield and includes much of the UConn campus in its upper reaches. The project is in response to a “Total Maximum Daily Load” (TMDL) developed by CT DEP for Eagleville Brook. TMDL’s are part of the Clean Water Act, and are usually written using target levels of specific pollutants, like nitrogen or bacteria. In the case of Eagleville, which testing showed to have overall impairments due to stormwater runoff, CT DEP developed an impervious cover TMDL which targets reductions in the amount and impact of impervious surfaces in the watershed. It is the first of its kind in the entire nation, and many believe the wave of the future in water regulation for urbanized watersheds suffering from stormwater-generated maladies. Stay tuned….
A new, cutting-edge interactive mapping website will be unveiled soon that will allow Connecticut residents to access a wide array of digital information about their neighborhood, watershed or town. Connecticut Environmental Conditions Online, or CT ECO for short, is a partnership between CT DEP and CLEAR, funded in part by the Office of Responsible Growth of the CT Office of Policy and Management.
A new publication on riparian buffers is available from the CT NEMO and Sea Grant programs for coastal landowners. The pamphlet, “A Planting Guide for Riparian Sites along the Connecticut Coast,” describes Connecticut’s coastal habitats, the functions and importance of buffers to these habitats, and how to plant a buffer. A companion piece listing plants appropriate for a variety of coastal habitats will be available soon. For more information contact Juliana Barrett at firstname.lastname@example.org.
The University of Connecticut Center for Land Use Education and Research (CLEAR) has just released the next version of its Connecticut’s Changing Landscape project, which now charts changes to the face of Connecticut over a 21-year period, from 1985 to 2006. During that period, the “footprint” of development-related land cover classes gained about 218 square miles, almost exactly matching losses to forest and agricultural fields (figure).
The project, which has become a much-used resource since 2002 for many communities and organizations, uses satellite-based remote sensing data to characterize land cover at certain points in time, and land cover changes over time. Version 2 updates the study to 2006, with data for each of the five study years (1985, 1990, 1995, 2002 and 2006) and landscape change over the entire 21-year period. Version 2 is also an enhancement: it now includes specific information on agricultural fields, which had previously been unavailable, as well as other improvements that improve the overall accuracy of the data.
CLEAR’s NEMO Program has just released a booklet that goes over basic information about “buildout” analyses. A buildout analysis is a projection of how much development would occur in a community if it were to build on every available acre of land, given certain constraints. In recent years, buildouts have been much discussed as a tool to help inform local planning. But what exactly is entailed in doing a buildout? How accurate is it? What software (if any) and data do you need?A supplement to an existing NEMO workshop, this booklet goes over buildout basics, including the limitations, data needs and educational uses of this planning tool. The publication is based on a study conducted in 2006-2007 by CLEAR in collaboration with Central Naugatuck Valley Council of Governments, funded by Connecticut Office of Policy and Management. The study made comparisons of three different buildout analyses of varying degrees of sophistication, in the interest of exploring the implications for a statewide buildout study.
The booklet can be downloaded at: nemo.uconn.edu/tools/publications/ about_buildouts.pdf.
In 2008 the Connecticut Land Use Academy completed the first full calendar year of its new format, providing training for 300 land use commissioners from 120 towns across the state. The Academy, which is largely funded by the Office of Responsible Growth of the Connecticut Office of Policy and Management, provides “basic training” for new and continuing commissioners focusing on knowledge and skills that they need in their role as land use decision makers. The new format consists of four day-long training workshops in different locations of the state over the course of the year.Each workshop is comprised of three sessions: Roles and Responsibilities, Legal Requirements (taught by the Connecticut Bar Association), and Map Reading for Site Plan Review. It’s a lot to get through in one (long) Saturday, but for those hardy souls who make the commitment, it seems to be worth it! About 91 percent of post-training survey respondents were “satisfied” or “very satisfied.”
And who are these folks? Based also on the surveys, it appears that slightly over half of Academy attendees are Planning and/or Zoning commissioners. Inland Wetlands and Watercourse and/or Conservation commissioners were also well-represented, with Zoning Boards of Appeal and Economic Development commissions having less representation.
Despite the success of the basic Academy training, most people would agree that when it comes to education of local land use officials, more is needed. Of course, CLEAR outreach programs like Nonpoint Education for Municipal Officials (NEMO), Land Use Planning Program, Geospatial Training Program and Green Valley Institute cover a lot of ground, particularly when it comes to conducting workshops on all the aspects of natural resource-based planning. However, the Academy is also expanding its reach.
The first “Hot Topics in Land Use” conference, sponsored in partnership with the Connecticut Bar Association Planning and Zoning section and the Connecticut Chapter of the American Planning Association, was held in November of 2008. The conference included nine workshops on a wide variety of topics, including farmland preservation, affordable housing, village and historic districts, economic development, downtown revitalization and form-based zoning. The plan is for Hot Topics to be held every other year, alternating with the Land Use Law Conference sponsored by the Connecticut Bar.
Look for the 2009 Land Use Academy information, plus the new “Online Academy” section, on the website: clear.uconn.edu/lua.
The National NEMO Network, which now comprises 32 programs in 30 states, won the 2008 national award from USDA as the Outstanding Integrated Water Resources Program.
The CT NEMO Program won the 2008 Communications Award from the Connecticut Chapter of the American Plan Association for its set of three interrelated websites focused on Low Impact Development (LID). Visitors can get information from the CT DEP Stormwater Quality Manual, use Google Maps to visit and get information about LID emplacements around the state, or search for LID-friendly land use regulations currently in use in Connecticut towns. Visit NEMO’s low impact development websites at:nemo.uconn.edu/tools.htm.
The Geospatial Training Program has just released its 2009 schedule. In addition to the ever-popular Geographic Information Systems (GIS) and Global Positioning System (GPS) courses, the Program has added new courses on creating Google Maps “mash-ups” and using remote sensing and imagery in the context of your GIS. For more information visit: clear.uconn.edu/geospatial/training.htm.
CLEAR graduate student Mark Hoover is working on a study of inundation of key marsh habitats along Long Island Sound. The work, which is supported by a grant from The Nature Conservancy Connecticut Chapter, models the competing forces of sea level rise and marsh accretion, and makes predictions about the fate of the marshes along the coast.
NEMO’s Online Community Resource Inventory, which is used by about 1200 different people per month to access maps of their town, has now added coastal habitat data layers to its list of maps. Visit: nemo.uconn.edu/tools/cri.
08/08 - CLEAR Hosts CT 2000 LiDAR Data Set and Derived Products
Connecticut's 2000 LIDAR data set has been made available via the World-Wide-Web on the CLEAR web site at http://clear.uconn.edu/data/ct_lidar/index.htm. These data include the "raw" positions provided as ASCII text, the positions provided as in ESRI point cloud, ESRI triangulated irregular networks (TIN), and ESRI shapefiles of the contours. The data are subdivided into quarter-quarter quadrangles that align with the USGS 7.5' topographic map series boundaries, have SPCS83 0600 planimetric coordinates and orthometric heights referred to NAVD 88, all in US Survey feet. This project resulted in a poster presentation in May 2008 given by Mr. John L. David at the Second National Lidar Meeting in Reston, VA. A copy of this poster can be viewed on the CLEAR Publications page.

CLEAR has released its first major progress report, detailing the Center’s activities for the first five years of its existence, 2002 – 2007. The report contains comprehensive lists of Center publications, partners, awards, and externally-funded grants. More important, however, are the pages that include brief descriptions of our landscape research, analytical tool development, technical training, and outreach education projects. You can request a paper copy of the report by emailing CLEAR Associate Director Chet Arnold, or download or view a copy on the CLEAR Publications page.
05/07 - CLEAR Creates Statewide Elevation Dataset
Investigators at CLEAR have created a statewide elevation dataset through the interpolation of airborne LiDAR data collected in 2000. These data are provided as gridded elevation on a USGS quadrangle basis. They have a spatial resolution of 10 feet and are projected into Connecticut State Plane, NAD83. This product emerged from a student projectstarted in Summer 2006 and continuing into Spring 2007, in which the students were modeling storm-related surge along Connecticut's shoreline. These elevation data are a research product and not intended for use in management, regulation, litigation, or related activities. They are intended for research, education, and demonstration purposes. More information on the data and the methods by which they were derived can be found in the metadata and a presentation developed by the student research team.

08/05 - CLEAR and NEMO Featured in the UConn Traditions Magazine
An article about CLEAR and NEMO was recently published in the UConn alumni magazine, UConn Traditions. The article focuses primarily on “Connecticut’s Changing Landscape,” the CLEAR project that is tracking statewide changes in land cover since 1985.
The article can be found at uconnmagazine.uconn.edu/smmr2005/smmr05f2.html.
The Center for Land Use Education and Research (CLEAR) was recently presented by the University Environmental Policy Advisory Council (EPAC) with a 2004-2005 ENVIRONMENTAL LEADERSHIP AWARD, in the category of University-affiliated Group. Winners were selected based on proven dedication and outstanding contributions to the principles of environmental leadership as outlined in UConn’s Environmental Policy Statement. The first-ever awards were presented to CLEAR Director Dan Civco and other CLEAR staff at a special ceremony on Earth Day, April 22, 2005.
CT NEMO recently printed its first official impact report dedicated to the work of the NEMO Program in Connecticut. The report describes the origin, objectives and progress of the program and includes a number of exciting new initiatives that have begun during this past year.
The main body of the Report, however, is given over to portrayals of selected towns that have worked with NEMO, and the ways that these towns are taking charge of their community’s future development patterns. The report profiles Old Saybrook, Waterford, Woodstock, Salem, Central Naugatuck Valley, Watertown, East Haddam, Candlewood Lake Authority and Stonington. The examples detailed in the report, while they represent only a portion of the good work being done around the state, demonstrate the power of local citizens to bring about positive change in their communities.
To order a copy of the report, free of charge, visit the NEMO website's Publications section. The profiled areas (Old Saybrook, Waterford, Woodstock, Salem, Central Naugatuck Valley, Watertown, East Haddam, Candlewood Lake Authority and Stonington) are also available as individual .pdf files for easy online viewing.Back to Top
The CT NEMO Program Team will be providing training around the state during 2005 on the new Stormwater Quality Manual by CT DEP. A number of key constituents will be targeted including municipal officials, town and consulting civil engineers, landscape architects, public works departments, state employees and others. View the manual at: http://dep.state.ct.us/wtr/stormwater/strmwtrman.htm
An article about CLEAR and NEMO was recently published in Earth Imaging Journal, a fairly new high-profile publication in the remote sensing world. EIJ is published by private sector remote sensing interests, and is not a peer-reviewed journal. However, their interest in our work (they solicited the article), and the fact that they put it on the cover of the hard copy journal, is a good sign indicating our growing national recognition. Interestingly, we assumed that they wanted to know all about our latest CLEAR research, but the Editor kept asking us for more about NEMO and the on-the-ground results of our work. Thus, there are nice breakout boxes on both CT and National NEMO. The e-article is at: http://www.eijournal.com/Local_Decisions.aspBack to Top
The Geospatial Technology Program recently conducted a 5-day, hands-on GIS training class at the UConn Storrs Campus. The class attracted professionals from regional planning organizations, conservation commissions and public utilities, and included town planners, assessors, college faculty and consultants.
Back by popular demand, a second class is currently being held at the Haddam Extension Center. The class is being taught using recently acquired lap top computers. GTP plans to use this “mobile class room” to host additional training classes at sites throughout the state in 2005, and beyond. GTP is in the process of redesigning and enhancing a hands-on, field-based GPS for GIS class. This class will be particularly suitable for lands trusts, conservation commissions and nonprofit organizations.Back to Top

Connecticut's Changing Landscape project got a bit of press this past winter. Below are several articles, originally printed in The Hartford Courant.

The Center for Land use Education And Research (CLEAR) has just released a new series of four dates of land cover data (1985, 1990, 1995 and 2002) for the state of Connecticut. These data, prepared from medium resolution satellite imagery, provide for the first time a consistently defined and interpreted set of land cover data that will allow state, regional and local planners to evaluate and study landscape changes over a seventeen year period. The data will be valuable to many organizations and government agencies as the state increasingly begins to deal with issues concerning development, sprawl, traffic congestion, forest loss and other aspects of landscape change.
The land cover data were interpreted from Landsat satellite imagery. Sensors aboard the satellite detect radiation reflected from the earth’s surface and store these data as images. The images, which are made up of millions of squares with a ground resolution of 30 meters (~ 100 feet) on a side, are converted via computer programs and human expertise into land cover maps. Land cover, as its name implies, shows the "covering" of the landscape. This is to be distinguished from land use, which is what is permitted, practiced or intended for a given area. For example, an area of low-density rural residential land use, as permitted by local zoning, likely will appear as forest in a Landsat image – there are a lot more trees than houses. Similarly, downtown Hartford, which is classified mostly as a “Developed” land cover is a mixture of uses that include offices, restaurants, stores, apartments, roads, parking lots, etc. From the satellite image it’s not possible to determine what the land uses are but we can describe the area as being developed.
The land cover data include eleven consistently defined classes and include: developed areas, turf and grass, other grasses and agriculture, deciduous forest, coniferous forest, water, non-forested wetlands, forested wetlands, tidal wetlands, barren areas, and utility rights-of-way. In preparing the data, care was taken to insure the accuracy of land cover classifications from one time period to the next thereby making it possible to conduct change analyses.
The land cover maps and a number of interpreted products can be viewed on the CLEAR website and each of the four dates of data can be downloaded for use in geographic information systems. http://clear.uconn.edu/projects/landscape/index.htm
