  • Previous Zoning: I-A and I-B
  • Previous Zoning Description: The previous I-A (Light Industrial) zoning allowed for offices, business, and light industrial uses, while the I-B (General Industrial) zoning was for more intensive industrial uses, explicitly prohibiting new residential development. Both were intended to support industrial economic activity.

This decision approves an official zoning map amendment for two parcels located at 4235 N Columbine Street and 2535 E 40th Avenue in the Elyria Swansea neighborhood of Denver, Colorado. The property, totaling 4.57 acres (198,902 square feet) and mostly vacant with some accessory structures, was previously zoned I-A (Light Industrial) and I-B (General Industrial). The City Council approved the rezoning to I-MX-3 (Industrial Mixed Use - 3 stories), which permits a broad range of light industrial, residential, and commercial uses. The I-MX-3 district allows for a maximum height of 3 stories or 45 feet for General and Industrial building forms and 38 feet for Town House building forms. This change enables residential development, which was not permitted under the previous industrial zonings. The rezoning was unanimously recommended for approval by the Planning Board and received support from several neighborhood organizations. The decision aligns with Denver's Comprehensive Plan 2040 and the Elyria & Swansea Neighborhoods Plan, promoting mixed-use infill development, increased housing options, and active pedestrian areas on public streets.
