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.

Buildings on the list are also subject to follow-up inspections by the Department of Buildings at least every 12 months, and once removed from the list, continuing inspections until the building receives two consecutive inspections, at least six months apart, during which no serious violations are found. The owners of buildings included on the list are designated as "building code scofflaws." Pursuant to the ordinance, as amended in 2021, lists of buildings are published on September 1 and March 1 of each year and lists of owners associated with those buildings are published one month later. The structure of this dataset was modified on 9/1/2021 to be consistent with the amended ordinance.
