slide-27
SLIDE 27

Zoning Ordinance – 3 Substantive Changes

  • 1. New Zoning District: Character District 4-W (“West End”)
  • Based on CD4, adjusted for off-street parking
  • Includes incentive overlay district for community space & workforce housing
  • 2. Incentives for inclusion of workforce housing or community spaces

in developments in the West End

  • Similar to existing incentives in North End (height, coverage, footprint &

parking)

  • 3. Increase Allowed Building Footprints in CD4 & CD5
  • Reflect existing downtown development pattern
  • Allow further increase in ground-level footprints to accommodate off-street

parking on a ground floor or underground level
