North Carolina's regulatory flood protection elevation is generally 2 feet above the Base Flood Elevation for non-coastal communities, including Apex.

What permits do I need to build in an Apex flood zone?

A Floodplain Development Permit under Section 6.2.7 of the Apex Unified Development Ordinance for any development inside a FEMA Special Flood Hazard Area — that includes new construction, additions, substantial improvements, grading, filling, and accessory structures. The lowest floor of any new or substantially improved residential structure must sit at or above the regulatory flood protection elevation (typically BFE plus 2 feet of freeboard in non-coastal NC). Substantial improvement or substantial damage equal to 50% or more of the pre-improvement market value triggers full-compliance reconstruction. Apply through the Apex Planning Department at (919) 249-3426.
