4.7 BUILDING SETBACKS A. Setback area requirements facilitate the incorporation of publicly accessible open space while reinforcing a continuous urban street frontage that defines the street edge. Setback requirements are designed as a range so that variety may be achieved in the public/ private interface area depending on the site and building design and its relationship to adjacent developments. Setbacks are designed to coordinate with the public improvements identified in the Metro East Public Realm Amenity Plan (Appendix). New development within the MEMO Overlay Zone shall be designed to provide setback areas from private or public streets as follows: Adjacentto public street right-of-way or _- 10ft(4) public easement Adjacentto alley or internal aisle aft -- Adjacentto parking 7 ft ClearZone 25 ft -- Adjacentto any residential use lstand2ndfioor 15 ft --- 3rd floor and above (5) 20/30 ft Adjacentto all other uses All floors 5 ft Up to 3rd floor 6 ft 4th floor and above 15 ft -- Notes 1. Setbacks are measured from the closest point of a building to the property line or public easement, except for clear zones. If a front yard/porch frontage is used, the building facade may be setback a maximum of 15 feet. 2. Additional setbacks for entry plazas or courtyards, or to meet adjacent structures, may be permitted subject to additional design review. Frontage types may be used to satisfy setback requirements. 3. Building planes above 3rd floor shall have, at a minimum, a 50% variation in setback within the specific standards in Table 4. 4. If a development project has multiple frontages, the maximum setback along one street frontage may be exceeded if the area is used for publicly -accessible open space. 5. For building with seven or more stories, the third floor and above must be set back a minimum of 30 feet from any residential use. 6. Clear Zones: a. Clear zones are required at driveway, street, or alley intersections to provide adequate line of sight for drivers, bicyclists, and pedestrians as they approach intersections. The clear zone shall consist of an isosceles right triangle with 25 -foot sides along the property line. b. The clear zone shall not be occupied by a ground floor building facade. Site and building features that are taller than 30 inches in height, including utilities, mechanical equipment, fences, and landscaping, are prohibited in the clear zone. c. Upper floors may extend over the clear zone. Awnings must maintain a vertical clearance of at least 15 feet within the clear zone. B. In addition to the above setback requirements, the following provisions shall also apply to new development projects: 1. In order to encourage flexibility and provide an organic feel in the design and building -street interaction, there is no minimum setback requirement within the MEMO Overlay Zone, with the exception that all structures shall maintain the maximum rear setback specified if the property abutting on the rear property line is developed solely as a residential use. 2. Setbacks abutting public right-of-way may be further recessed from the maximum setback specified for the purpose of a public open space, dining/gathering or special entry area. These areas may not satisfy private open space requirements. 3. Setbacl<s abutting public rights-of-way shall be landscaped with lawn, trees, shrubs, or other plants and/or decorated as a hard surface expansion of the sidewalk. A combination of landscape and hardscape materials shall be provided as follows: a. Hardscape paving may include brick, stone, interlocking concrete pavers, textured concrete, and/or impressed patterned concrete. Hardscape elements shall also be provided when setback area is being used to satisfy publicly accessible open space areas. These elements may include, but are not limited to, seating areas, potted plant materials, water features, and public art installations. b.The balance of the setback areas shall be landscaped with turf, shrubs, or groundcover, and trees. All plant materials shall be in proportion to the height and mass of the buildin, and shall be permanently maintained.
