"Survey: All topographic surveys shall be based from an official benchmark acceptable to the City, and be based on the NGVD 1988 datum. Because the FEMA flood map elevations currently utilize NGVD 1929 as well as older city record drawings, the surveyor/designer/developer shall utilize the appropriate conversion factor to convert to the NGVD 1988 datum. All temporary benchmarks for construction purposes are to be based off accepted City benchmarks."
