Wall Height 30 ft.

• RMF zone increase

from 30 to 35 ft.

– Match roof height – Meet planned density – Increase number of full stories – Increase design and development options – Match 35 ft. wall height for accessory structures Existing Code

the first 60 ft. abutting a residential zoning district

Existing Transition Standards

• Landscape buffer
• Minimum setbacks

– adjacent to RSF, RTF residential zones

• Parking

Existing Transition Standards

• Lot size

– Only sites 2+ acres in RSF zone – If subdivision proposed

LOT WIDTH AND FRONT LOT LINE

Attached Houses

• RTF, RMF, RHD zones,

sites without alley parking: Reduce from 36

• ft. to 25 ft.

– Match minimum for duplexes – Meet planned density – Increase design and development options

Building Envelope

• Reduce the side setback
• pposite the common wall to

the standard from the double requirement to the standard for other development

– Remove impediment to attached housing – Match minimum for duplexes – Increase design and development options
