Description: Core forest areas are derived from the following categories of the RIGIS 2020 Andersen Level 3 Landuse/Landcover Classification410...Deciduous Forest (>80% hardwood) (Formerly Brushland in 1995) 420...Coniferous Forest (>80% softwood) 430...Mixed Forest DESCRIPTION: Trees are classified as forests when the tree canopy covers at least 50% of the space when viewed from above on an aerial photograph. The three different categories depend upon the composition of deciduous vs. coniferous trees. On an aerial photograph, most coniferous trees have conical shapes (except for pines) with dense needles and tight branching with dark spectral signatures whereas deciduous trees have a more open or freeform shape with leaves (during the growing season) that give the tree a coarser texture or pattern and a looser or more open branching arrangement. Deciduous spectral signatures are generally lighter than coniferous signatures.The three forest categories were merged to a single classification of forest, areas within 75 yards of a road were eliminated, and forest blocks < than 250 acres were removed.

Description: Vector polygon represenations of all RI Water Subject to CRMC Regulation as described in the Publication "The State of Rhode Island, Coastal Resources Management Program, As Amended" (aka, The Redbook) Section 200 Tidal and Coastal Pond Waters A. The six categories of waters defined in this Program are directly linked to the characteristics of the shoreline, since the activities on the adjacent mainland are the primary determinant of the uses and qualities of any specific water site.The dataset was developed for cartographic and planning purposes only. Introductory Findings Rhode Islanders have a deep commitment to their coastal environment. Their concern for Narragansett Bay and the South Shore coastal ponds has been voiced in numerous ways, including support of landmark legislation in 1971 that created the Coastal Resources Management Council, endorsement of many of the efforts of environmental organizations such as Save the Bay and the Audubon Society of Rhode Island, and passage of the largest bond issue in the state's history in order to relieve chronic pollution in upper Narragansett Bay caused by the antiquated Providence municipal sewage treatment plant. The concerns of the public have in large measure been responsible for decisions not to build oil refineries in Jamestown and Tiverton, and to halt the indiscriminate destruction of salt marshes and the improper disposal of dredged spoils. Narragansett Bay is widely accepted as the state's greatest resource, and our coastal waters and shoreline are the focus not only of tourism but of efforts to attract new businesses into the state. Rhode Island strives to maintain the image of a desirable place to work and raise a family, and these attributes are inextricably bound to a varied and beautiful shoreline, where water quality and, no less important, visual quality are excellent and well protected. The qualities that make Rhode Island's coast beautiful and an unparalleled recreational resource are fully as important as the more readily quantifiable commercial and industrial water-dependent activities. The designation of large stretches of waters or coastline for conservation and low-intensity use by this Program recognizes these facts and will help maintain a high quality of coastal environment for future generations of Rhode Islanders.The six categories of waters defined in this Program are directly linked to the characteristics of the shoreline, since the activities on the adjacent mainland are the primary determinant of the uses and qualities of any specific water site. Type 1 waters abut shorelines in a natural undisturbed condition, where alterations, including the construction of docks and any dredging, are considered by the Council as unsuitable. Type 2 waters are adjacent to predominantly residential areas, where docks are acceptable, but more intense forms of development, including more marinas and new dredging projects (but not maintenance dredging), would change the area's character and alter the established balance among uses. Alterations such as these would bring more intensive uses and are therefore prohibited in Type 2 waters. The waters along some 70 percent of the state's 420 miles of shoreline have been assigned to Type 1 and Type 2, and should be expected to retain their high scenic values and established patterns of low-intensity use. Type 3 waters are dominated by commercial facilities that support recreational boating. Here, marinas, boatyards, and associated businesses take priority over other uses, and dredging and shoreline alterations are to be expected. Type 4 areas include the open waters of the Bay and the Sounds, where a balance must be maintained among fishing, recreational boating, and commercial traffic. Here high water quality and a healthy ecosystem are primary concerns. The last two water use categories are assigned to areas adjacent to ports and industrial waterfronts. In these waters, maintenance of adequate water depths is essential, high water quality is seldom achievable, and some filling may be desirable. Within Type 5 ports, a mix of commercial and recreational activities must co-exist, while in Type 6 waters, water-dependent industrial and commercial activities take precedence over all other activities.The water categories described in this section are complemented by policies for shoreline types (Section 210), and the two must be combined to identify the Program's policies for a specific coastal site. More than 90 percent of Rhode Island's tidal waters are classified by the R.I. Department of Environmental Management as SA, the highest water quality rating. Water pollution, however, is a major concern, with eutrophication and bacterial contamination a growing concern in the salt ponds and with all major indicators of pollution showing strong gradients down the Bay from the Providence metropolitan area. Despite the pollutants and intense fishing pressure, Rhode Island's tidal waters support large seasonal populations of a variety of finfish. In the Bay, the quahog supports a large and important commercial fishery. Recreational fishing for flounder, bluefish, and striped bass is important nearshore. Rhode Island has a rich history of maritime commerce and industry. In this century, however, the once-booming urban waterfronts of the upper Bay have stagnated and declined despite major infusions of public funds to deepen the access channel to Providence to 40 feet and build new terminal facilities. During the postwar decades, oil imports have dominated waterborne commerce, but this sector has declined sharply since the mid-seventies. In 1973, the U.S. Navy announced a major pullout from its extensive facilities in the lower Bay, and by 1980 hundreds of acres of port facilities at Quonset, Davisville, Melville, and Coddington Cove had been turned over to the state. The State of Rhode Island now owns a large inventory of unutilized or underutilized port facilities. As commercial shipping has declined, recreational boating has increased. Facilities for the in-water storage of boats are in short supply, but with very few exceptions expansion of marinas into new areas could only be accomplished if remaining salt marshes and other important natural features were sacrificed. Since this is considered unacceptable by the Council, the emphasis must be on the more efficient use of existing facilities, recycling of underutilized but already disturbed sites, and improvements to public launching facilities. Activities that are dependent on Rhode Island's tidal waters generate substantial economic benefits to the state. Nearly one billion dollars are generated each year by such water-related activities as marine industry, transportation and education, commercial fishing and marine recreation (Farrell and Rorholm, 1981). Substantial additional economic benefits are generated by water-enhanced residential development, tourism, and the importance of an attractive marine environment in drawing high-quality businesses to Rhode Island.

Description: RI's EJ Area delineation is derived from EPA New England's Potential Environmental Justice (EJ Areas) are based on the 2000 Census Block Group Boundary layer. The methodology used to determine how the areas are coded involved identifying those blockgroups with percentages in the top 15% of the region for low-income residents and/or racial minorities. The one significant difference between the RI delineation and the initial EPA delineations is that RI chose blockgroups with percentages in the top 15% of the STATE for low-income residents and/or racial minorities whereas EPA chose blockgroups based on their ranking across all of EPA Region 1. The result is a slightly larger and more inclusive area than EPA's.
Description: "Environmental justice focus area" means a census tract that meets one or more of the following criteria:(i) Annual median household income is not more than sixty-five percent (65%) of the statewide annual median household income;(ii) Minority population is equal to or greater than forty percent (40%) of the population;(iii) Twenty-five percent (25%) or more of the households lack English language proficiency; or(iv) Minorities comprise twenty-five percent (25%) or more of the population and the annual median household income of the municipality in the proposed area does not exceed one hundred fifty percent (150%) of the statewide annual median household income.

Description: Description: MS4 Regulated Area as of 2021, which includes the Urbanized and Densely Populated Areas as defined by the RIPDES Regulations and based on the 1990, 2000, and 2010 decennial census data.
Description: RI Natural Heritage Areas serves as an aid in the conservation of state listed rare, threatened or endangered plant and animal species found in Rhode Island.The Natural Heritage Areas were developed from a kernel density analysis of Heritage data element occurrences (EO). The calculation, based on a 30 meter pixel size, determines the mean number of EOs per square kilometer for each pixel within a one kilometer search radius. Non-statistically significant areas were eliminated and the remaining areas converted to a polygon dataset. Element Occurrences are discreet observations of a community or nesting site of State or Federally listed rare or threatened species OR species deemed noteworthy by the State.

Description: The Rhode Island Water Resources Board requires all large water supplies (suppliers that withdraw greater than 50 million gallons annually) to submit updated Water Supply System Management Plans (WSSMP) every five years. A requirement of the WSSMPs is an updated water supplier district coverage. This dataset includes: district coverages for 25 large water suppliers that are required to submit WSSMPs, Block Island (not required to submit a WSSMP), and a separate feature for the Connecticut side of the Westerly district coverage. Also, some water district boundaries were created by providing a1000ft buffer from the end of water lines defined in 2005. A buffer was created to ensure that all buildings served within the district are included, though this may cause some potential errors and some buildings not served by the supplier may be included within the buffered area.
