Traditional Neighborhood Development Infill (TND-I) ZoningTraditional Neighborhood
Development Infill District (TND-I)
TND-I District: This district is intended to enhance and complement existing communities and villages by integrating new uses and structures
into the existing community fabric, encouraging reuse and revitalization of existing structures, strengthening connections within communities to
improve walkability and expand traditional, human scale, pedestrian oriented neighborhoods, and providing a strong orientation to transit service.
This district provides flexible development standards for infill parcels so that properties can be developed in a way that is compatible with adjacent
properties in historic communities, to help create a "complete" walkable and transit-friendly community with housing, jobs, services, civic uses
and open space. The district is intended to implement specific comprehensive plan recommendations for the County's Villages, Village Expansion
Areas, Urban Expansion Areas and Urban Development Areas to promote the redevelopment of older, historic areas.
Qualifying lands: Lands qualifying for inclusion in the TND-I district shall be tracts located in areas mapped as Urban Development Areas,
Urban Expansion Areas, Villages and Village Expansion Areas in the Comprehensive Plan and that are generally served by, or planned for, public
sewer and water service. If the proposed development will require public sewer and water service, the applicant must demonstrate to the
satisfaction of the Board of Supervisors that there is sufficient available sewer and water capacity to accommodate the proposed development at
full build out and/or provide a plan demonstrating that such improvements will be phased to accommodate projected development as it occurs.
Area requirements and Mix of Uses: The area required for a Traditional Neighborhood Infill (TND-I) district shall not be more than ten (10)
acres since this district is targeted at undeveloped or underdeveloped lots in established communities rather than creating new communities.
The tract of land to be developed shall be under single ownership, or shall be the subject of an application filed jointly and subject to a single
concept plan. A mix of uses is encouraged.
Development Density: The permitted maximum and minimum development densities in the TND-I district shall conform to density guidelines

(3) dwelling units per acre. In areas designated in the comprehensive plan as urban expansion areas and urban development areas
gross residential densities shall not exceed twelve (12) dwelling units per acre.
• In areas designated in the comprehensive plan as, village, or village expansion areas, non-residential gross floor area ratios shall not
exceed 0.25 F.A.R. In areas designated in the comprehensive plan as urban expansion areas, urban development areas non-residential
gross floor area ratios shall not exceed 0.40 F.A.R.
• For non-residential or mixed use development less than one (1) acre, higher densities may be approved by the Board of Supervisors to
promote redevelopment.
