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.

    Beach Lab Data

    data.cityofchicago.org | Last Updated 2021-09-09T20:00:25.000Z

    The Chicago Park District collects and analyzes water samples from beaches along Chicago’s Lake Michigan lakefront. The Chicago Park District partners with the University of Illinois at Chicago Department of Public Health Laboratory to analyze water samples using a new DNA testing method called Rapid Testing Method (qPCR analysis) which tests for Enterococci in order to monitor swimming safety. The rapid testing method (qPCR analysis) is a new method that measures levels of pathogenic DNA in beach water. Unlike the culture based test that requires up to 24 hours of processing, the new rapid testing method requires a 4-5 hours for results. The Chicago Park District can use results of the rapid test to notify the public when levels exceed UPEPA recommended levels, which is 1000* CCE. When DNA bacteria levels exceed 1000 CCE, a yellow swim advisory flag is implemented. For more information please refer to the USEPA Recreational Water Quality Criteria (http://water.epa.gov/scitech/swguidance/standards/criteria/health/recreation). Historically, the Chicago Park District used the culture based analysis method and statistical prediction models to monitor beach water quality. The culture based method tests for Escherichia coli (E. coli) bacteria which is an indicator species for the presence of disease-causing bacteria, viruses, and protozoans that may pose health risks to the public. This method requires 18-24 hours of processing to receive results. The Chicago Park District would use results of the culture based method to notify the public when levels exceed UPEPA recommended levels, which is 235* CFU. When bacteria levels exceed 235 CFU, a yellow swim advisory flag was implemented. This standard is still used at most beaches throughout the Great Lakes region. For more information please refer to the USEPA Recreational Water Quality Criteria. The statistical prediction model forecasted real-time Escherichia coli (E. coli) bacteria levels present in the water. The Chicago Park District (CPD) in partnership with the US Geological Survey, developed statistical prediction models by using weather data pulled from CPD buoys (https://data.cityofchicago.org/d/qmqz-2xku) and weather stations (https://data.cityofchicago.org/d/k7hf-8y75). The Chicago Park District would use results of the predictive model to notify the public when bacteria levels would exceed 235 CFU. When bacteria levels exceed 235 CFU, a yellow swim advisory flag was implemented. * The unit of measurement for Escherichia coli is Colony Forming Units (CFU) per 100 milliliters of water. (Culture Based Method / Statistical Prediction Model) *The unit of measuring DNA is Enterococci Calibrator Cell Equivalents (CCE) per 100 milliliters of water. (Rapid Testing Analysis)

Deer Wintering Areas - Forested areas managed to provide severe winter habitat for herds of white tail deer on Crown lands. Other Habitats - Designated forested stands meeting D.N.R.’s structural and spatial criteria for “Old Forest Communities” and “Old Forest Wildlife Habitats”. Formerly Designated Deer Wintering Areas - Formerly designated Deer Wintering Areas which aerial surveys have not detected animal use in for significant time. One component of the changes to the designated “Conservation Forest” announced with the forest strategy in March, 2014. Formerly Designated Habitats - Formerly designated forested stands which met D.N.R.’s structural and spatial criteria for “Old Forest Communities” and “Old Forest Wildlife Habitats”. One component of the changes to the designated “Conservation Forest” announced with the forest strategy in March, 2014. Additional Information: Please be aware of the following: Watercourse and Wetland Buffers - Not all watercourses defined in N.B.’s legislative framework are mapped due to difficulty in delineating watercourses from colour aerial photography. Watercourse locations are generally accurate to within 10 m. Deer Wintering Areas - Deer wintering areas are identified on the basis of periodic aerial surveys and may not completely identify all forested stands being used by deer. / Cet ensemble de données comprend les cinq couches cartographiques suivantes : Zones tampons des cours d’eau et des terres humides : Zones tampons entourant les terres humides et les cours d’eau cartographiés où sont réglementées les activités forestières sur les terres de la Couronne pour préserver la qualité de l’eau et l’habitat aquatique. Aires d’hivernage du cerf de Virginie : Zones forestières aménagées sur les terres de la Couronne pour fournir aux troupeaux de cerfs de Virginie des habitats les protégeant des hivers rigoureux. Autres habitats : Peuplements forestiers désignés qui répondent aux critères structuraux et spatiaux du DER concernant les « communautés de forêt ancienne » et les « habitats fauniques de forêt ancienne ». Anciennes aires d’hivernage du cerf de Virginie : Anciennes aires d’hivernage du cerf de Virginie pour lesquelles les relevés aériens n’ont pas décelé d’utilisation animale pendant une longue période de temps. Il s’agit d’une des modifications à la forêt de conservation qui ont été annoncées au titre de la stratégie de gestion des forêts, en mars 2014. Anciens habitats : Anciens peuplements forestiers qui répondaient aux critères structuraux et spatiaux du DER concernant les « communautés de forêt ancienne » et les « habitats fauniques de forêt ancienne ». Il s’agit d’une des modifications à la forêt de conservation qui ont été annoncées au titre de la stratégie de gestion des forêts, en mars 2014. Renseignements supplémentaires : Veuillez noter les points ci-dessous. Zones tampons des cours d’eau et des terres humides : Tous les cours d’eau définis dans le cadre législatif du Nouveau-Brunswick ne sont pas cartographiés, compte tenu de la difficulté à les délimiter à partir des photographies aériennes en couleurs. En général, l’emplacement des cours d’eau est précis à plus ou moins 10 m. Aires d’hivernage du cerf de Virginie : Les aires d’hivernage du cerf de Virginie sont définies en fonction de relevés aériens périodiques et il se peut que ces derniers n’aient pas pu déceler totalement tous les peuplements forestiers utilisés par les cerfs.
