Procedures for determining one percent annual chance flood elevation (100 -year flood elevation) in Zone A: In a designated Zone -A area, applicants shall provide the information required in Section 1301.06, Subd. 2 of this Chapter to determine the 100 -year flood elevation and the regulatory flood protection elevation for the subdivision site.
