Table 5‐18 provides an analysis of allowable building heights for each of the
zoning districts in the city and where they occur in each imaginary surface
with a green box indicating compatibility, a yellow box indicating potential
compatibility depending of the approved height, and a red box indicating
incompatibly. The Zoning Code allows a maximum height of 110 feet. This elevation in the
Approach / Departure Clearance Surface roughly begins after the first few
shoreline parcels. While the maximum height of structures on most parcels
within the Waterfront Zoning District would be compatible with the
Imaginary Surfaces, a handful of parcels within this zoning district are not.
Agricultural, Single Family Residential, Multi‐Family Residential, Residential
Office, and Neighborhood Commercial Zoning Districts have an allowable
height of up to 35 feet. General Commercial and Industrial have an
allowable height of 50 feet as does Interstate Commercial districts that are
located south of I‐10 (for structures north of I‐10 there are a maximum
height of 60 feet). The Mixed‐Multifamily Residential Zoning District allows
structures up to 3 stories and the French Market Zoning District allows
structures up to 4 stories. Additionally, the D’Iberville Zoning Ordinance identifies “Radio, TV Towers or
Similar” as conditional uses in the General Commercial (C‐2), Interstate
Commercial (C‐3), and Industrial (I) zoning districts. There are no specific
regulations in the Zoning Ordinance related to telecommunication tower
heights; however, buildings and structures are limited to 170 feet in the
Keesler AFB Imaginary Surfaces. As an accessory structure, heights may
increase above the 170‐foot maximum height of the associated zoning
district by one foot for every additional foot of setback provided, posing the
potential for incompatibility with the Imaginary Surfaces.
The greatest height allowance in the City of D’Iberville is in the Waterfront
Zoning District, which allows structures up to 110 feet. The Waterfront
District, located along the waterfront of the Back Bay of Biloxi, is potentially
compatible with the Keesler AFB Transitional and Approach / Departure
Surfaces. The Transitional Surface applies to a handful of properties in the
Waterfront District near the eastern boundary of D’Iberville along the
shoreline. Assessing whether the permitted height in the Waterfront District
complies with the Transitional Surface, is dependent on where the
development is sited on the property relative to the maximum 110 foot
height for that surface; therefore, there is potential for development in this
area to be incompatible with the Imaginary Surfaces.
The Waterfront District is also within the Approach / Departure Clearance
Surface. The proximity of land in D’Iberville to the end of the Approach /
Departure Clearance Surface at the runway varies from approximately
4,900 feet to 6,300 feet. This yields an allowable height of 100 to 126 feet
at the shoreline since the Approach / Departure Clearance Surface is a
sloping surface with a 50:1 ratio (1 vertical foot for every 50 horizontal feet).
