Congress Park Overlay Proposed Zoning Standards

1. Currently for alterations and / or expansion of an existing one- or two-unit dwelling, the code allows for up to 40% demolition of a residence. Of that percentage, the Overlay would allow only 10% of the total demolition to be in the front façade.
2. Maintain traditional side setbacks
   1. Keep the existing side setback that is typical for that block, including sky exposure, solar access, rear garages and narrow driveways
3. Reduce height in feet and stories
   1. Pitched roof: Two stories capped at 28’ but can add dormers that pierce the bulk plane. (Currently 30’ height allowed)
   2. Two story flat roof capped at 22’.
   3. Bulk plane vertical height at side interior wall 14’ (Currently 17’ is allowed)
4. Decreasing the 37.5% allowable lot coverages by 2.5%. to 35%. On a 50-foot lot that potentially amounts to 125 s.f. decrease of footprint on the lot. On a 37.5’ lot that would equate to 117 s.f. The lower roof height, lower wall height and elevated floor lines, the mass / bulk on the lot will decrease but still allow for expansion of an existing residence while also providing for better integrated new infill projects.
5. Allow dormers to pierce the bulk plane
6. Low slope or flat roof require a front setback on second floor
7. Require porches
   1. Require front porches to be a minimum of 6 x 20’, must have a minimum 18’ height and not be under a story.
8. Minimum first floor elevation
   1. First floor elevation must be no less than12” above grade and no more than 36” above grade
