Downtown Form-Based Code

DFD 507. Tree Lists

1. A.
   General

   1. 1.
      The following lists contain all approved tree species for use in a Form District. The lists include native and acceptable adapted species. Other species may be used for planting within a private lot. These lists may be periodically amended by the City Forester.
   2. 2.
      Invasive exotic species may not be used anywhere on private lots or other areas.
2. B.
   Street Trees

   1. 1.
      Species in the Street Tree List are for placement as shown in Street Type Specifications, or as specified in the regulating plan for placement along the Street Tree Alignment Line. The use of alternate species may be permitted, but only if approved by the City Forester.
   2. 2.
      Street Trees are part of an overall Street-Space plan designed to provide both canopy and shade and to give special character and coherence to each street. The desired aesthetic must be achieved through the use of native and/or proven hardy adapted species. Appropriate Street Tree species may grow and change over time and these lists may be periodically amended by the City Forester. Inclusion in this list shall be based on the following criteria:

      1. a.
         Structural – Street Trees shape and subdivide the Street-Space, increasing pedestrian comfort and adding (literal) value to the street/community. “Canopy Shade Tree” species grow to heights in excess of 50 feet and have a broad canopy—enabling them to clear auto traffic and pedestrians, form a ceiling-like enclosure, and open a clear view of the Street-Space, Façades, and Shopfronts at eye-level.
      2. b.
         Design – Species are planted consistently along a given Street-Space to provide a special form and character. This provides species diversity at the same time it provides a specific street character by planting different Street-Spaces with different trees.
      3. c.
         Street Tree List

         (Large Canopy Trees – mature height 60 feet and above)

4. 4.
   Public Space Trees - in addition to the Street Trees, the following trees may be placed within Dooryards, Squares or Civic Greens.
