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.

    Iowa Medicaid Payments & Recipients by Month and County

    mydata.iowa.gov | Last Updated 2024-04-30T22:00:20.000Z

    This dataset contains aggregate Medicaid payments, and counts for eligible recipients and recipients served by month and county in Iowa, starting with month ending 1/31/2011. Eligibility groups are a category of people who meet certain common eligibility requirements. Some Medicaid eligibility groups cover additional services, such as nursing facility care and care received in the home. Others have higher income and resource limits, charge a premium, only pay the Medicare premium or cover only expenses also paid by Medicare, or require the recipient to pay a specific dollar amount of their medical expenses. Eligible Medicaid recipients may be considered medically needy if their medical costs are so high that they use up most of their income. Those considered medically needy are responsible for paying some of their medical expenses. This is called meeting a spend down. Then Medicaid would start to pay for the rest. Think of the spend down like a deductible that people pay as part of a private insurance plan.

    Enterprise Zones

    Enterprise Zones. Zone III originated in 1995 with a 20-year time-span. This zone primarily covered areas in the Downtown area and commercial and industrial properties north of the James River and west of I-95. At that time a portion of residential parcels was included. Eight (8) years later, Henrico County and the City of Richmond applied for a Joint Zone (connecting at Broad Street and Brook Road). At that time, the original 20-year zone time was retained. The Joint Zone (Zone III/formerly North Zone) had a sunset date of December 31, 2014. In 2012, Henrico County contacted the Virginia Department of Housing and Community Development (DHCD) requesting that they be allowed 20 years for Zone III as a joint zone resulting in a sunset date of December 31, 2022. At the end of 2014, both the City and Henrico County applied for a Redesignation of Zone III from DHCD; the Redesignation application was approved in January of 2015 by the Virginia Commonwealth resulting in an extension of Zone III for both the City and Henrico County. The official sunset date was set at December 31, 2022. Contentwise, the Redesignated Zone III encompasses the commercial and industrial areas north of the James River including and west of I-95. Also, commercial corridors north of the James River and east of I-95 are included as well as Shockoe Bottom. Lastly, the Hull Street and Hull Street Road Corridors, Belt Boulevard between Hull Street Road and Midlothian Turnpike and Midlothian Turnpike corridor between the City line and Belt Boulevard are incorporated.
