Dallas Form Districts
Existing Code Problems
• Unpredictable Outcomes• Districts Do Not Create Urban Places• “One Size Fits All” Approach• Each Project Involves Negotiation • No Districts to Implement Transit-
Oriented Development (TOD)
The Dallas Code is friendly to developments like this . . .

New Code Approach
forwardDallas! mixed use building blocks provide context for differentiating mixed use standards
Transit Center Urban Mixed Use Multi-Modal Corridor
Campus District Main Street Urban Neighborhood
New Code Approach
• New Districts Designed as Base Zoning Options
• Form-Based Codification – Additional graphics and improved page
layout– Includes Minor Streets Standards
New Code Approach
• Hierarchy of Elements:
– ZONING DISTRICTS: Districts Applied Based on forwardDallas! Policy Guidance
– BUILDING TYPES: Building Types Allowed in Specified Districts
– PERMITTED USES: Uses Allowed in Specified Building Types
New Code Approach
Three New Districts:– Urban Mixed Use (UMU-)
• Low, Medium, High Intensity• 3-Stories . . . 8-Stories . . . 12-stories
– Urban Residential (UR-)• Low, Medium, High Intensity
– Residential Transition (RTN)• Low Intensity Only
New Code Approach
Two Frontages– Shopfront
• Requires single- or multi-story shopfront building with retail on ground floor
• Accommodates large-format retail, not just “main street”
– Mixed Use Shopfront• Requires multi-story shopfront building with
retail on ground floor• Vertical mixing of uses (residential or office
above retail)

Streets and Streetscape
Variety of streetscape plates can be matched to a variety of street types
Implementation
• Enabling Legislation Only– NOT Location-Specific Zoning Changes– No Map Changes– Each Map Change Considered as a
Rezoning• The Goal is to Enable Good, Urban
Mixed-Use in Specific Target Areas– Around Transit Stations (TOD)– Along Transit Corridors
The View from the Jury: Current issues in FBC writing
• Use of building types: when and how?
• Is enabling urbanism enough?
• The importance of a clear vision?
• Optional codes?
