Supplemental Information:

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 authourized 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.

Data 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.

Process Steps

Process Step 1

CC ID: 207550

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.

Process Step 2

CC ID: 207551

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)
