This release of data includes the chloride concentration of water samples provided by the USGS or other organizations that were used for this mapping effort. The inland extent of saltwater at the base of the Biscayne aquifer in the Model Land area of Miami-Dade County, Florida, was mapped in 2011. Since that time, the saltwater interface has continued to move inland. The interface is near several active well fields; therefore, an updated approximation of the inland extent of saltwater and an improved understanding of the rate of movement of the saltwater interface are necessary. A geographic information system was used to create a map using the data collected by the organizations that monitor water salinity in this area. A rate of saltwater interface movement of 140 meters per year was estimated by dividing the distance between two monitoring wells (TPGW-7L and Sec34-MW-02-FS) by the travel time. The travel time was determined by estimating the dates of arrival of the saltwater interface at the wells and computing the difference. This estimate assumes that the interface is traveling east to west between the two monitoring wells. Although monitoring is spatially limited in this area and some of the wells are not ideally designed for salinity monitoring, the monitoring network in this area is improving in quality and spatial distribution. The approximation of the inland extent of the saltwater interface and the estimated rate of movement of the interface are dependent on existing data. Improved estimations could be obtained by installing uniformly-designed monitoring wells in systematic transects extending landward of the advancing saltwater interface.

The Miami-Dade County storm surge planning zones are drawn using Sea, Lake and Overland Surge from Hurricanes (SLOSH) model grids that incorporate local physical features such as geographic coastal area, bay and river shapes, water depths, bridges, etc. Areas in Miami-Dade along canals, rivers and further inland have been identified as being at risk for storm surge based on this data. The Miami-Dade County storm surge planning zones are drawn using Sea, Lake and Overland Surge from Hurricanes (SLOSH) model grids that incorporate local physical features such as geographic coastal area, bay and river shapes, water depths, bridges, etc.Areas in Miami-Dade along canals, rivers and further inland have been identified as being at risk for storm surge based on this data. Each zone or portions will be evacuated depending on the hurricane’s track and projected storm surge, independent of the hurricane’s category. Upon identification of a threat the EOC or County Mayor will use local media to relay pertinent information, such as evacuations and shelter openings. It is important that you monitor the news for this information

Data pertaining to mapping the approximate inland extent of saltwater at the base of the Biscayne Aquifer in the Model Land Area of Miami-Dade County, Florida in 2016. The inland extent of saltwater at the base of the Biscayne aquifer in the Model Land area of Miami-Dade County, Florida, was last mapped in 2011.

A line feature class of Miami-Dade County's Urban Development Boundary(UDB) boundaries. The boundary was adopted by the Board of County Commissioners (BCC) as per recommendation. This boundary identifies the area where urban development may occur through the year 2030. Development orders permitting urban development will generally be approved within the UDB at some time through the year 2030 provided that level-of-service standards for necessary public facilities will be met. Adequate countywide capacity will be maintained within the UDB by increasing development densities or intensities inside the UDB or by expanding the UDB when the need for such change is determined to be necessary through the amendment process.Revisions: Date: November 2021 By: Juan C. Pelaez Reason: The Urban Development Boundary (UDB) is updated as a result of Comprehensive Development Master Plan (CDMP) amendment approvals, and is subject to Interpretation by the Director of the Regulatory and Economic Resources (RER) Department where there are questions pertaining to its alignment.Last updated November 2021.

Based on the Miami-Dade County Digital Flood Insurance Rate Map (DFIRM), effective September 11, 2009 published by FEMA and the ASCE 24 guidelines. 'Coastal A� Zone according to FEMA, is the area landward of a V Zone or landward of an open coast without mapped V Zones. In a coastal A Zone, the principal source of flooding will be astronomical tides, storm surges, seiches or tsunamis and not riverine flooding. During base flood conditions, the potential for breaking wave heights between 1.5 feet and 3.0 ft, will exist.Updated: Not Planned The data was created using: Projected Coordinate System: WGS_1984_Web_Mercator_Auxiliary_SphereProjection: Mercator_Auxiliary_Sphere

The map shows the 8-class vegetation cover developed from Landsat TM data used for the SICS area.

This map was created specifically for surface-water flow velocity indexing within hydrodynamic models created by the U.S. Geological Survey. Vegetation classes in this map represent mixes of vegetation types that share structural characteristics and ranges of flow resistance as determined through field, laboratory, and hydrodynamic model experiments. Some of these vegetation types are more typically segregated into separate classes. Therefore, the user is cautioned not to treat this map as a standard vegetation classification. This map's characteristics and your requirements should be carefully considered before adopting this map for your particular use. Surface water flow velocity in the wetlands of Taylor Slough, Everglades National Park, is controlled by factors such as water depth, land-surface gradient, wind effects, and the type and density of vegetation. To evaluate the effect of vegetation on this shallow surface-water flow for model development, it is necessary to extrapolate from point measurements of velocity and surface-water slope made concurrently with characterization of vegetation at locations throughout the slough to the entire model area. This map was created solely for the purpose of extrapolating field and laboratory measured vegetation resistances to flow to the area of Taylor Slough/The Everglades National Park being modeled in the Southern Inland Coastal System (SICS) model domain.

The SICS study area is located in the southeast quadrant of Everglades National Park (ENP). It encompasses the interface of the wetlands of the Taylor Slough and southern C-111 canal drainage basins with nearshore tidal embayments of Florida Bay. The study area is bounded on the east by U.S. Highway 1, and C-111 canal and levee; on the north and west by ENP Road (SR27) and Old Ingraham Highway; and on the south by Florida Bay.

This is the 1st release of the third version of an Everglades Depth Estimation Network (EDEN) digital elevation model (DEM) generated from certified airborne height finder (AHF) and airboat collected ground surface elevations for the Greater Everglades Region. This version includes all data collected and certified by the USGS prior to the conclusion of the AHF collection process. It differs from the previous elevation model (EDEN_EM_JAN07) in that the modeled area of WCA3N (all the WCA3A area north of I-75) is increased while the modeled area of the Big Cypress National Preserve (BNCP) has been both refined and reduced to the region where standard error of cross-validation points falls below 0.16 meters. EDEN offers a consistent and documented dataset that can be used to guide large-scale field operations, to integrate hydrologic and ecological responses, and to support biological and ecological assessments that measure ecosystem responses to Comprehensive Everglades Restoration Plan. To produce historic and near-real time maps of water depths, the EDEN requires a system-wide DEM of the ground surface.

This layer is designed to be used for plotting of maps and identify specific collection areas where these boundaries will be required to be identified. The purpose of the Park Impact Fee Collection Areas is to provide not only for the minimum level of service established by the CDMP, but also for the additional public park open space and recreation facilities necessary to adequately serve the impacts and demands of new residential development; and to require that future residential growth contribute its fair share to the cost of additions and improvements to the County's public park system in amounts reasonably anticipated to offset the impacts and demands generated by such growth. All park impact fees collected by the Department of Planning and Zoning shall be promptly deposited into the proper account in the local park trust fund. General administrative charges collected by the Department of Planning and Zoning shall be directed to the park impact fee administrative fund account for the purpose of paying the cost of administering determinations of credits, contributions, suitability and this chapter.Updated: Every 10 yrs The data was created using: Projected Coordinate System: WGS_1984_Web_Mercator_Auxiliary_SphereProjection: Mercator_Auxiliary_Sphere
