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.

    This dataset contains is a list of Iowa features contained in the Geographic Names Information System (GNIS). The GNIS is the Federal standard for geographic nomenclature. The U.S. Geological Survey developed the GNIS for the U.S. Board on Geographic Names, a Federal inter-agency body chartered by public law to maintain uniform feature name usage throughout the Government and to promulgate standard names to the public. The GNIS is the official repository of domestic geographic names data; the official vehicle for geographic names use by all departments of the Federal Government; and the source for applying geographic names to Federal electronic and printed products of all types. See http://geonames.usgs.gov for additional information. The Geographic Names Information System contains information about physical and cultural geographic features of all types, current and historical, but not including roads and highways. The database assigns a unique, permanent feature identifier, the Feature ID, as a standard Federal key for accessing, integrating, or reconciling feature data from multiple data sets. The GNIS collects data from a broad program of partnerships with Federal, State, and local government agencies and other authorized contributors.

    State of Iowa Accountable Government Act Reports and Plans

    data.iowa.gov | Last Updated 2017-11-02T18:22:40.000Z

    The Iowa Department of Management is responsible for implementing and administering the state's Performance Management System established in 2001 through the Iowa Accountable Government Act. Iowa's performance management system provides a framework for actively using performance data to improve state government results so we can better serve customers. This framework ensures executive branch state agencies have sound performance planning and reporting, strategic planning and proven results. Agency strategic plans identify essential goals, strategies, and measures to guide progress in achieving the department's vision and mission as well as define how the agency contributes to achievement of the enterprise goals. Agency performance plans look at the agency's mission (the purpose or why the agency exists) and define the operations (core functions and key services, products and/or activities) that are in place to achieve that mission. Agency performance reports compare actual performance with projected levels for key areas outlined in the agency strategic plan and the agency performance plan. Agency performance plans are due to the Iowa Department of Management on December 15th for the preceding fiscal year.
