17.18.10 Signs

Signs shall be consistent with the requirements detailed in Chapter 17.69 Signs.

All multi-family projects that contain 16 or more units shall be required to provide an onsite manager.

The following standards shall apply to all multi-family developments:

• A. The architectural design of multi-family developments to the best extent possible should be compatible with adjacent residential neighborhoods. Compatibility may involve the use of materials, color, scale, roof pitch, and other physical features that would assist in blending the new multi-family development with surrounding residential uses.

• B. The architectural design of multi-family developments that are not adjacent to or within existing residential neighborhood shall adhere to the following design standards:

  1. Long, unbroken building facades and box-like building forms should be discouraged. Alternating building planes, building material, color and building heights, should vary building facades. Other approaches to providing interesting multi-family structures could involve alternating the patterns of window and door opening; the use of projections such as balconies, porches and awnings; and changing setbacks and softening the building facade with tree plantings.

  2. Setbacks should be varied with individual structures.

  3. The rooflines of multi-family structures should be altered to provide a more interesting horizontal view. No metal roofs shall be permitted.

  4. There should only be a maximum of two adjacent multi-family units with identical wall and roofline planes.

  5. It is important that door and window openings be articulated on the face of the multi-family structure. Articulation can include framing, insets or shudders for windows and insets, framing and color for doorways.

6. Materials used for multi-family developments should be durable and of low-maintenance. Where possible, exterior siding should provide a distinctive appearance, such as river rock, brick, or flagstone.

18-9

Exeter Zoning Ordinance Chapter 18: RM Zone (Multiple Family Residential)

7. Stairways should be designed as an integral part of the overall multifamily development. Materials used on the building should be incorporated into the stairway design. Stairways should not be a dominant exterior feature on the building but should be sited so that they are not visually prominent.

==> picture [373 x 170] intentionally omitted <==

8. The maximum height for multi-family developments shall be two (2) stories.

• C. Parking lots and driveways should be designed to blend in with the overall multifamily project.

  1. Long, unbroken rows of parking spaces are discouraged. Where possible, these rows should be broken by landscaped islands, buildings, or garages.

  2. Carports should contain some design elements that make the structures visually interesting, such as finished roofs or articulated support beams.

  3. Parking lots should be screened from adjacent properties with a 7-foot solid block wall that is softened with landscaping.

• D. Special design treatment should be given to the entryways and street corners of multi-family projects.

  1. The street corners of multi-family projects should be enhanced visually with features like landscaping, walls, lighting, fountains, trellises, signage or public art.

• 17.18.13 Energy Conservation

• A. To the greatest extent possible, the multi-family buildings should run east and west to take advantage of passive solar design opportunities.

• B. All ground-mounted heating/cooling units shall be located on the east side of a building that fronts onto an east/west roadway, and on the north side of a building that fronts onto a north/south roadway. (This location feature will conserve energy.)

• C. The landscaping plan for the multi-family complex should plant deciduous trees on the south and west sides of the residential complex. (This location design feature will conserve energy.)
