To: Planning and Zoning Commission
From: Dennis Killough, AICP –Director of Planning & Development Services
Subject: Ordinance No. 480-GGGGG amendments to the City of Southlake
Zoning Ordinance No. 480, as amended, Section 47 - Transition Zoning
District (TZD)
Action
Requested: Conduct a public hearing and consider approval of the proposed Ordinance
No. 480-GGGGG.
Background
Information: As Southlake develops, the City periodically reviews its regulations to
ensure they align with the City’s development priorities. The TZD is a
district of regulations originally established in 2005 to encourage well-
designed residential neighborhood developments while allowing flexibility
for mixed-use projects that blend housing, retail, offices, and civic spaces.
The purpose of this request is to review the ordinance to ensure it continues
to serve its intended purpose and that it aligns with the community’s long-
term vision. Since its original creation on August 2, 2005, the TZD district
has undergone four amendments.
The discussion surrounding the most recent requests for TZD zoning
changes have focused on density, density calculation methods, lot area
and width, open space and adjacency standards. The amendments being
proposed provide options to address these areas.
The TZD areas are shown in green on the map below. Regardless of any
changes that are adopted to the ordinance, current property owners within
the TZD areas will remain under their existing zoning regulations that were
adopted under their zoning approval and can continue to use and improve
their property under those regulations. However, the amendments being
proposed and ultimately adopted may affect a property owner’s ability to
make future changes to the TZD zoning district uses and regulations on
their property.
