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.

    GCWW Private-side One-off Lead Service Line Replacements | Last Updated 2020-04-01T09:31:28.000Z

    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 prequalified list established through the City's Request for Qualifications (RFQ) process. This dataset is the list of jobs from the prequalified list of plumbers established through the RFQ process. For more information on the GCWW Lead Service Line Replacement Program please visit the GCWW Lead Awareness site If you are a plumber and are interested in learning more about how you can get involved, please view the Plumber FAQ.
