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.

    2012 Maui Island Plan Boundaries - Agricultural Preserves Layer. Source: Maui County Planning Department, August 2022. See also Maui Island Plan Growth Areas, Maui Island Plan Growth Boundaries, Maui Island Plan Protected Areas layers. Maui Island Plan Growth Boundaries adjusted to Maui County Finance Department Real Property Assessment Division’s daily parcels, early 2022. Some boundaries match Real Property Assessment’s 2022 parcel release but some are aligned to parcels which were refined after that release. Maui Island Plan was passed in 2012. Growth Boundaries, Growth Areas, Protected Areas, and Agricultural Preserves are defined by documents available here: https://www.mauicounty.gov/1503/Maui-Island-Plan. GIS layers are based on the documents but are aligned to match features like parcels, roads, and boundaries visible on Pictometry imagery.
