Figure 18-7 is shown with corresponding height limits for reference; however, Table 18-3 shall control.
b. In squares along Tchoupitoulas Street, the maximum building height of Table 18-3 shall be achieved by line-of-sight from the opposite side of Tchoupitoulas Street methodology established in Figure 18-8 over the base zoning district’s 85 ft. height limit.
