1. Transferring Existing CBRS Lines to DOQ Imagery CBRS boundaries are digitized and overlaid on horizontally-controlled DOQ aerial photography

2. Remapping FSUs Three types of boundary adjustments are required: –Changes to “fit” DOQ imagery –Adjustments to match documented boundary intent –Changes to account for geomorphic change as mandated by the 5-year review legislation

3. FSU Changes to “Fit” DOQ Imagery Note boundary relationship to road Note location of features for alignment

4. FSU Adjustments to Reflect Intent Administrative Record indicates boundary was intended to exclude existing development Note boundary relationship to infrastructure on 1979 base map

5. FSU Adjustments to Reflect Intent Administrative Record indicates boundary was intended to exclude existing development Note boundary relationship to infrastructure on 1979 base map Note boundary relationship to construction completed 1981

6. FSU Adjustments to Reflect Intent Refinement of boundaries based on digital property parcel data –Note boundary relationship to trailer park identified on 1979 base map

7. FSU Adjustments to Reflect Intent Research indicates this FSU should follow specific property boundaries. The digital parcel data (in purple below) allows the CBRS boundaries to be adjusted to reflect intent.

8. FSU Geomorphic Changes Note boundary relationship to stream

9. FSU Geomorphic Changes Note boundary relationship to stream

10. Remapping OPAs OPA remapping is significantly different from FSU remapping All owners / managers of protected lands must be contacted –Intensive outreach and coordination is key Examples follow to demonstrate: –Transferring existing OPA boundaries to DOQs –Overlaying parcel data representing multiple landowners –Adjustment of CBRS lines to property / parcel data

11. Remapping OPAs Note location of features for alignment

12. Remapping OPAs Overlay County parcel data Determine 1990 land ownership Identify potential addition issues Private Dauphin Island Park & Beach Board U.S. Coast Guard Sea Lab (University of Alabama) DIPB Board land Leased to Sea Lab DIPB Board RV park (not desired for inclusion)

13. Remapping OPAs Coordinate with land managers to “fit” boundaries to photographic base Obtain land manager’s signature to show concurrence that OPA includes only eligible, intended lands Stakeholder Concurrence Stakeholder SignatureUS FWS Signature

14. Remapping OPAs Recommended OPA boundary Private Dauphin Island Park & Beach Board U.S. Coast Guard Sea Lab (University of Alabama) DIPB Board land Leased to Sea Lab DIPB Board RV park (not desired for inclusion) AL-05P

15. Benefits of Digital Orthophoto Base Map Visual cues facilitate identification of existing development Enhanced precision in mapping geomorphic features Location of planimetric features Ability to overlay and analyze digital parcel data Horizontal spatial control of boundary lines
