3. T he information depicted on this map represents the results of surveys made on the date indicated and can only be considered as indicating the general conditions existing at that time.

4. T he location of navigation aids are provided by the U.S . Coast Guard, NOAA or the Corps of Engineers. Consult U.S . Coast Guard Light List and U.S . Coast P ilots for supplemental information.

5. Base imagery prepared from natural color four band imagery provided by the National Agriculture Imagery P rogram (NAIP ) tak en by United S tates Department of Agriculture (2015).

6. Every effort has been made to provide all pertinent details on the location of obstructions/utilities. T he data furnished on the drawings are believed to be substantially correct. However, the exact locations may vary from that shown.
