Land Area

Water Area

Land area is a measurement providing the size, in square miles, of the land portions of geographic entities for which the Census Bureau tabulates and disseminates data. Area is calculated from the specific boundary recorded for each entity in the Census Bureau's geographic database. Land area is based on current information in the TIGER® data base, calculated for use with Census 2010.

Water Area figures include inland, coastal, Great Lakes, and territorial sea water. Inland water consists of any lake, reservoir, pond, or similar body of water that is recorded in the Census Bureau's geographic database. It also includes any river, creek, canal, stream, or similar feature that is recorded in that database as a two- dimensional feature (rather than as a single line). The portions of the oceans and related large embayments (such as Chesapeake Bay and Puget Sound), the Gulf of Mexico, and the Caribbean Sea that belong to the United States and its territories are classified as coastal and territorial waters; the Great Lakes are treated as a separate water entity. Rivers and bays that empty into these bodies of water are treated as inland water from the point beyond which they are narrower than 1 nautical mile across. Identification of land and inland, coastal, territorial, and Great Lakes waters is for data presentation purposes only and does not necessarily reflect their legal definitions.

    The dataset represents the lakes participating in the Citizen Statewide Lake Monitoring Assessment Program (CSLAP). CSLAP is a volunteer lake monitoring and education program that is managed by DEC and New York State Federation of Lake Associations (NYSFOLA). The data collected through the program is used to identify water quality issues, detect seasonal and long term patterns, and inform volunteers and lake residents about water quality conditions in their lake. The program has delivered high quality data to many DEC programs for over 25 years.The dataset catalogs CSLAP lake information; including: lake name, lake depth, public accessibility, trophic status, watershed area, elevation, lake area, water quality classification, county, town, CSLAP status, years sampled, and last year sampled.

    Surface Water Quality Assessments

    opendata.maryland.gov | Last Updated 2018-08-13T20:15:11.000Z

    This is the 2014 Integrated Report. EPA approved this submission in accordance with Sections 303(d), 305(b), and 314(l) of the Clean Water Act, on October 16, 2015. The Integrated Report (IR) combines two water quality reports required under sections 305(b) and 303(d) of the federal Clean Water Act. Section 305(b) requires states, territories and authorized tribes to perform annual water quality assessments to determine the status of jurisdictional waters. Section 303(d) requires states, territories and authorized tribes to identify waters assessed as not meeting water quality standards(see Code of Maryland Regulations 26.08.02). Waters that do not meet standards may require a Total Maximum Daily Load to determine the maximum amount of an impairing substance or pollutant that a particular water body can assimilate and still meet water quality criteria. Historically, the 303(d) List and the 305(b) report were submitted to the Environmental Protection Agency (EPA) as separate documents but more recent guidance has called for combining these two reports into a single biennial publication.

    GCWW Private-Side One-off Lead Service Line Replacements

    data.cincinnati-oh.gov | Last Updated 2022-07-04T02:54:13.000Z

    Data Description: To reduce the expose to lead in drinking water, Greater Cincinnati Water Works (GCWW) has created a Lead Service Line Replacement Program (LSLRP). In October 2016, GCWW was directed by the City of Cincinnati Council, via Ordinance No. 326-2016, to take the appropriate steps to develop, fund, and implement a program to replace known lead service lines in the City, both on public and private property. Through another ordinance, Ordinance No. 185-2017, and effective July 28, 2017, lead service lines are prohibited in the GCWW system. Enforcement of this ban is being phased in over time. The private-side work is then done by contractors or plumbers who are contracted with GCWW through the City's procurement process, either for a water main replacement project, or from a pre-qualified list established through the City's Request for Qualifications (RFQ) process. This dataset is the list of jobs from the pre-qualified list of plumbers established through the RFQ process. Data Creation: This data set is the list of jobs from the pre-qualified list of plumbers established through the RFQ process. Data Created By: GCWW Refresh Frequency: For more information on the GCWW Lead Service Line Replacement Program please visit the GCWW Lead Awareness site https://lead.mygcww.org. If you are a plumber and are interested in learning more about how you can get involved, please view the Plumber FAQ. Data Dictionary: A data dictionary providing definitions of columns and attributes is available as an attachment to this data set. Processing: The City of Cincinnati is committed to providing the most granular and accurate data possible. In that pursuit the Office of Performance and Data Analytics facilitates standard processing to most raw data prior to publication. Processing includes but is not limited: address verification, geocoding, decoding attributes, and addition of administrative areas (i.e. Census, neighborhoods, police districts, etc.).
