Description: Estimated centerlines of real world roadways. Includes street names, address ranges, and other attributes especially useful for geocoding.These data were originally designed and developed for Rhode Island E 9-1-1 Uniform Emergency Telephone System (RI E 9-1-1) purposes. This dataset continues to be maintained to provide an accurate spatial reference for RI E 9-1-1 telecommunicators.Portions of this dataset were collected as early as 2001. Inaccuracies do exist in these data and are therefore under constant revision. Any discrepancies, inaccuracies or inconsistencies recognized in these data should be reported to the pertinent municipality who should alert RI E-911. Users are also encouraged to email ri911gis@akassociates911.com with any suggested updates for this actively maintained dataset.

Description: Overview - Lakes and Ponds originally derived through manual digitizing of USGS 1:24000 Topographic Maps. Features have subsequently been reviewed and corrected over 2020 ortho photos and 2011 LIDAR digital terrain model for spatial accuracy.Water Quality - Integrated Report - Prior to 2008, DEM submitted the 305(b) Report and 303(d) List as separate documents. Recent USEPA guidance recommends that states develop and submit an Integrated Water Quality Monitoring and Assessment Report (Integrated Report). This guidance recommends that states integrate their Section 305(b) water quality assessment report and their Section 303(d) Impaired Waters List into a single document. The Integrated Report is intended to provide a streamlined approach to assessing and reporting on water quality.The new federal guidance results in a fundamentally different scope, organization, and options for communicating about water quality than previous guidance for these individual reports. Five new categories of assessment determination replace the old 305(b) assessment terminology (fully supporting, threatened, partially supporting, not supporting) and the 303(d) List Group format previously utilized by DEM. The new format provides an Integrated List consisting of 5 categories of water quality assessment information, with the fifth category being the list of impaired waters needing a TMDL.Assessments may result in different use support attainment status for the different designated uses for individual waterbodies. For example, a waterbody may be Fully Supporting swimming use, but there may be insufficient data to develop an aquatic life use support status. The Integrated Report Categories are presented below with a description of how the results of the individual assessments for each designated use on a waterbody are integrated to determine the final Integrated Report Category for each waterbody. In general, the integration of assessment determinations follows a hierarchical approach where a determination of impairment for any cause for any of the waterbody's designated uses will result in placement of the waterbody in Category 5. Similarly, there is a hierarchical approach to placement of a waterbody into Category 4A over 4B over 4C. While each waterbody is placed into only one of the 5 reporting categories, the attainment status of each designated use for each waterbody is documented on the Integrated Lists to facilitate tracking of information and to assist in addressing data gaps and directing water quality monitoring efforts.Cold/Warm - An assessment by Division of Fish & Wildlife identifying cold or warm water fish habitat. SRPW_1 - Identifies Special Resource Protection Waters as identified in the DEM Water Quality RegulationsSW_Pot - Waters potentially impaired by storm water runoffSW_Con - Waters confirmed impaired by storm water runoffURL_1 - Link to USEPA Waterbody ReportIWQMA_AsmntType - Integrated Water Quality Monitoring and Assessment Type. Some lakes, especially some run-of-river impoundments, are assessed as linear river centerlines.
