These data represent the Critical Habitat for Johnson's Seagrass (Halophila johnsonii) in the State of Florida as designated by Federal Register Vol. 65, No. 66, Wednesday, April 5th, 2000, Rules and Regulations. Critical Habitat for Johnson Seagrass as of February 16th, 2012 with visual edits made based on existing maps. Please Note: This dataset only contains data present at the Florida extent.

In addition to the coordinates provided in the Federal Register document, the following data were used to assist in the production of this dataset: US Army Corps of Engineers - IWW_IR to DA.dgn (Microstation Design File depicting the Intracoastal Waterway), Miami Harbor 83-90.dgn (Microstation Design File depicting the federally authorized navigation channels in Miami Harbor; According to the USACE, these channels are likely to be updated in the near future). St. John's River Water Management District - cb24_det.e00 (ArcInfo Interchange format file, converted to an ArcInfo Coverage depicting a detailed shoreline, last update 12/10/99.) Edited February 2012. See process steps.

Use_Constraints:

Due to the collection of data used in this analysis from multiple data sources, some
instances occur where the USACE ICW file intersects areas of the SJRWMD file
classified as "Land", particularly in the vicinity of Hobe Sound. Clearly this is not the
real world situation and efforts will be made to resolve these conflicts in the data. At
this time, these were the best data available. The text description in 50 CFR Part
226 is always the one, true definition of Johnson's seagrass critical habitat. These or
any other depictions are for information purposes only and shouldn't be relied on for
regulatory purposes.

the boundaries of NMFS Regulated Areas in Northeast, Mid-Atlantic, and Southeast
Waters (Regulated Areas) only. The dataset should not be used for a legal
definition. The dataset should not be used to infer information regarding the
existence or details of other marine features or resources, including, but not limited
to, navigable waters, coastlines, bathymetry, submerged features, or man-made
structures. Users assume responsibility for determining the appropriate use of this
dataset. *** Not the Legal Definition *** This Geographic Information System (GIS)
dataset is not the legal definition of the Regulated Area. The description published
in the U.S. Code of Federal Regulations is the only legal definition. This dataset and
metadata document provide a broad overview of a subset of applicable fishing
regulations, restrictions and requirements, critical habitat or essential fish habitat; it is
not a substitute for the actual regulations. Users are encouraged to read the
applicable regulations in conjunction with use of this dataset. *** Temporal
Considerations *** Regulated Area boundary definitions are subject to change or
modification. Published datasets may represent historic, current, or future Regulated
Areas. When changes to fishing regulations affect this dataset, it will be archived
and replaced by an updated version as soon as feasible. Approved Regulated Area
boundaries may also be published prior to their effective date. It is the user s
responsibility to ensure the applicable Regulated Area boundaries are being used.
*** Shorelines/Base Layers *** The accuracy of this dataset is dependent upon the
accuracy and resolution of the datasets (e.g., shoreline, bathymetry, National
Hydrographic Database, shared administrative boundaries) used in the creation
process. Source datasets used are specified in the metadata. These data sources
were selected for their suitability to a broad audience, and may not be suitable for
specific uses requiring higher-resolution information. Coastlines change. Unless
otherwise noted, where the NOAA Medium Resolution Shoreline is used, assume
the regulatory boundary reaches the most current coastline delineation available.

A point layer was created using the coordinates in the Federal Register. Those points were then used to digitize polygons. The polygons were then "clipped" to a detailed shoreline (cb24_det.e00) obtained from St. John's River Water Management District (SJRWMD). Following the clip operation, microstation design files of the ICW and Miami Harbor navigation channels were obtained from the US Army Corps of Engineers (USACE) and converted to shapefiles. The final ICW shapefile was created by using a 62.5ft buffer on either side of the centerline and editing that buffer file to match the widening areas in the vicinity of the critical habitat areas. The final Miami Harbor shapefile was created by digitizing a polygon over the channel edge line work in the design file. An Edit Clip was then performed to "punch a hole" through the Critical Habitat areas where they intersected the ICW and the Miami Harbor navigation channel, thus excluding the federally authorized navigation channels from the Critical Habitat areas. Finally, the data in the vicinity of Miami Harbor in Biscayne Bay were edited visually to correspond to the paper maps in the federal register document. Additionally, all data used were reprojected to match the detailed shoreline. (UTM Zone 17, NAD 83, HARN)

2011/2012 edits to shapefile: (a) Indian River north Sebastian Inlet: I recreated the polygon according to eCFR 50 CFR 226.213 in 2007. (b) Indian River south Sebastian Inlet: OK (c) Indian River Lagoon - Fort Pierce inlet: OK (d) Indian River Lagoon - St. Lucie Inlet: I included the ICW in the shapefile, and created one solid polygon. I also redigitized the eastern side along the shoreline using Bing Maps as a background in ArcMap. (e) Hobe Sound: The coordinate in the FR is suppose to be at SR 708, but looking at Bing Maps, it is to the south. I edited the shapefile to continue north to SR 708. I also made one big poly that does not depict the ICW exclusion. The polygon shorelines were also edited to follow the Bing Maps background. (f) Jupiter Inlet: I digitized a boundary that followed the shoreline (again, employing heads-up digitizing techniques using Bing Maps). (g) Lake Worth: the original shapefile had a 4 vertice polygon that approximated the shoreline on the south side. I digitized the shoreline along the south side using Bing Maps as a guide. (h) Lake Worth Lagoon - Boynton Inlet: I edited the polygon to go all the way to the coordinates (the shape file does not exclude the ICW). I also redigitized the western edge to follow the Bing Maps shoreline. (i) Lake Wyman: The original shapefile excluded the ICW, so I redigitized the polygon to extend to the published coordinates. This unit did not follow the shoreline on the eastern side, so I redigitized it to follow the Bing Maps shoreline. (j) A portion of Northern Biscayne Bay, FL: I received a new Biscayne Bay Aquatic Preserve boundary from Florida DEP, Bureau of Survey and Mapping, Division of State Lands (rev. 2010). The boundary is from Section 258.39 (11) Florida Statutes, and Section 258.397. They send me the exterior boundary for the AP. They said that the law for the boundary has not changed, but the boundary is more accurate now. If there are questions about specific sites within the boundary, contact the Title and Land Records Section of the Bureau of Survey and Mapping Division of State Lands (850)245-2788.
