    The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).The file is georeferenced to earth's surface using the State Plane projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.

    Description

    Boundaries of Orleans Parish voting precincts as defined by the New Orleans City Charter. New Orleans voting precincts are drawn according to the New Orleans Home Rule Charter as required by the State of Louisiana. A precinct is defined in the state of Louisiana's election code as the smallest political unit of a ward having defined geographical boundaries. Precinct boundaries were updated September 25, 2015, in order to satisfy population changes discovered by the Orleans Registrar of Voters Office. The changes have been made by the City of New Orleans and verified by the Louisiana Secretary of State's Office. Information about voter registation can be found here: https://www.sos.la.gov/ElectionsAndVoting/Pages/RegistrationStatisticsParish.aspx https://www.municode.com/library/la/new_orleans/codes/code_of_ordinances?nodeId=PTIICO_CH58EL_ARTIIELPRState LawRS 18:532. Establishment of precinctsA. Subject to the provisions of R.S. 18:532.1 and 1903, the governing authority of each parish shall establish precincts, define the territorial limits for which each precinct is established, prescribe their boundaries, and designate the precincts. The governing authority of each parish shall by ordinance adopt the establishment and boundaries of each precinct in accordance with the timetable as set forth herein and in accordance with R.S. 18:532.1.B.(1)(a) Each precinct shall be a contiguous, compact area having clearly defined and clearly observable boundaries coinciding with visible features readily distinguishable on the ground and approved extensions of such features, such as designated highways, roads, streets, rivers, or canals, and depicted on United States Bureau of the Census base maps for the next federal decennial census, except where the precinct boundary is coterminous with the boundary of a parish or an incorporated place when the boundaries of a single precinct contain the entire geographic area of the incorporated place. Except as otherwise provided in this Paragraph, on and after July 1, 1997, any precinct boundary which does not coincide with a visible feature shall be changed by the parish governing authority to coincide with a visible feature in accordance with R.S. 18:532.1.(b) For the purposes of this Paragraph, the term "approved extension" shall mean an extension of one visible feature to another visible feature which has been approved by the secretary of the Senate and the clerk of the House of Representatives or their designees and which is or which will be a census tabulation boundary.(2) No precinct shall be wholly contained within the territorial boundaries of another precinct, except that a precinct which contains the entire geographical area of an incorporated place and in which the total number of registered voters at the last general election was less than three hundred may be so contained.(3) No precinct shall contain more than two thousand two hundred registered voters within its geographic boundaries. Within thirty days after the completion of each canvass, the registrar of voters of each parish shall notify the parish governing authority of every precinct in the parish which contains more than two thousand two hundred registered voters within its geographic boundaries. Within sixty days of such notification, the parish governing authority shall divide such precincts by a visible feature in accordance with R.S. 18:532.1.(4)(a) No precinct shall contain less than three hundred registered voters within its geographical boundaries, except:(i) When necessary to make it more convenient for voters in a geographically isolated and unincorporated area to vote.

    Description

    USGS and FEMA collaborated to collect data on residences in six of the twenty disaster-declared parishes in Louisiana during the August 8–11 floods in 2016. The National Map Corps (TNMCorps), a volunteer program run the National Geospatial Program of the U.S. Geological Survey, were invited to help with this task. From August 30 to September 30, 2016, Corps editors created and classified data points for each building within the six parishes. FEMA used this information to find which buildings in the parishes were residences, and to estimate by how many feet underwater the houses were. This data was then used to help determine the amount of assistance provided to homeowners in these parishes.The data points were summarized into 5 km hexagons (a process called hexbinning) to provide an easier visualization of the number of points collected by TNMCorps. Lighter colors indicate more buildings per hexagon. Per-hexagon numbers range from 1 to 1800.Map also includes flood extent estimates from FEMA and GOSEP (Louisiana Governer's Office of Homeland Security & Emergency Management). Parish outlines derived from U.S. Census TIGER data.

The information is gathered from the 911 Computer Assisted Dispatch System, and it does not include data from Baker Police, Central Police, Zachary Police, Louisiana State Police, LSU, or Southern University. The map will refresh automatically every 60 seconds.Disclaimer:This page contains raw data and unconfirmed information about traffic incidents as they have been reported to the East Baton Rouge Parish 911 computer aided dispatch (CAD) system. The possibility exists that an incident may have been reported or classified incorrectly.The information on this site is intended only as a general guide to possible traffic related situations being investigated by the Baton Rouge Police Department, East Baton Rouge Sheriff's Office, Emergency Medical Services, or Baton Rouge Fire Department. Incidents located in East Baton Rouge Parish that are being investigated by other agencies, including Baker Police, Central Police, Zachary Police, Louisiana State Police, or campus police at LSU and Southern University incidents are not reflected in this map. Because this information is derived from the 911 CAD system, the incident will remain on the page until the responding officer has been taken off the call. This may occur after the actual incident has been cleared from the roadway. Also, traffic incident points should be considered approximate, not exact locations.The City-Parish Department of Transportation and Drainage maintains the local road closure data which is displayed in this web map. More information about local road closures can be found on the EBR Road Closures webpage. This map displays data from the Louisiana Department of Transportation and Development. Included are the traffic camera locations and LA-DOTD road closures. These datasets are provided as a convenience for users. The City-Parish is not responsible for the information provided by LA-DOTD or its affiliates.The live and predictive traffic data comes directly from HERE. HERE collects data per month, and where available, users sensors to augment the collected data. An algorithm compiles the data and computes accurate speeds. The imagery is not live. Imagery is provided as a service from Esri, Inc. and image tiles are not updated each time the map is displayed.This site uses web mapping software from Esri, Inc. which has been purchased by the Baton Rouge City-Parish Government.Users are encouraged to submit their questions and comments related to the EBRGIS Program by sending an email to gis@brla.gov or contacting the Department of Information Services at (225) 389-3070.

    Description

    The 2022 cartographic boundary KMLs are simplified representations of selected geographic areas from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). These boundary files are specifically designed for small-scale thematic mapping. When possible, generalization is performed with the intent to maintain the hierarchical relationships among geographies and to maintain the alignment of geographies within a file set for a given year. Geographic areas may not align with the same areas from another year. Some geographies are available as nation-based files while others are available only as state-based files. The cartographic boundary files include both incorporated places (legal entities) and census designated places or CDPs (statistical entities). An incorporated place is established to provide governmental functions for a concentration of people as opposed to a minor civil division (MCD), which generally is created to provide services or administer an area without regard, necessarily, to population. Places always nest within a state, but may extend across county and county subdivision boundaries. An incorporated place usually is a city, town, village, or borough, but can have other legal descriptions. CDPs are delineated for the decennial census as the statistical counterparts of incorporated places. CDPs are delineated to provide data for settled concentrations of population that are identifiable by name, but are not legally incorporated under the laws of the state in which they are located. The boundaries for CDPs often are defined in partnership with state, local, and/or tribal officials and usually coincide with visible features or the boundary of an adjacent incorporated place or another legal entity. CDP boundaries often change from one decennial census to the next with changes in the settlement pattern and development; a CDP with the same name as in an earlier census does not necessarily have the same boundary. The only population/housing size requirement for CDPs is that they must contain some housing and population. The generalized boundaries of most incorporated places in this file are based on those as of January 1, 2022, as reported through the Census Bureau's Boundary and Annexation Survey (BAS). The generalized boundaries of all CDPs are based on those delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2020 Census.

    Tchefuncte River
    Description

    Heavy rainfall occurred across Louisiana during March 8-19, 2016, as a result of a massive, slow-moving southward dip in the jet stream, which moved eastward across Mexico, then neared the Gulf Coast, funneling deep tropical moisture into parts of the Gulf States and the Mississippi River Valley. The storm caused major flooding in north-central and southeastern Louisiana. Digital flood-inundation maps for a 32.4-mile reach within the community of Covington near the Tchefuncte River in Washington Parish and Tangipahoa Parish, LA was created by the U.S. Geological Survey (USGS) in cooperation with Federal Emergency Management Agency (FEMA) to support response and recovery operations following a March 8-19, 2016 flood event. The inundation maps depict estimates of the areal extent and depth of flooding corresponding to 24 high-water marks (HWM) identified and surveyed by the USGS following the flood event.

    Description

    The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create, and enhance Louisiana's coastal wetlands. The restoration plans developed persuant to these acts specifically require an evaluation of the effectiveness of each coastal wetland restoration project in achieving long-term solutions to arresting coastal wetland loss. This data set consists of digital data describing wetland land-water classification for the Fritchie Marsh Restoration for the year 2010. The land-water data were derived from interpretation of color infrared photography flown at 1:12000. All areas characterized by emergent vegetation, wetland forest, scrub-shrub, or uplands are classified as land, while open water, aquatics, and mud flats were classified as water.
