1282.11 DESIGN GUIDELINES
   The following guidelines shall be applicable to all new development, redevelopment, and all substantial expansion of parcels within the Central Business District.
   A.   Utilities
      1.   All utility lines for new projects shall be located underground.
      2.   Pedestrian Lighting
         a.   Pedestrian lighting structures are pole-mounted lights in the right-of-way that primarily function to illuminate pedestrian areas such as sidewalks. They are part of a secondary lighting system used to supplement street lighting levels.
         b.   Pedestrian lighting structures are to be placed in the Pedestrian Buffer area, not to encroach upon sidewalks, where possible.
         c.   Pedestrian lighting structures shall:
            i.   Be placed at equal intervals between streetlights, such that either a pedestrian light or a streetlight is established approximately per every twenty-five (25) feet of roadway.
            ii.   Be a maximum of eighteen (18) feet above grade.
            iii.   Decorative in nature and complementary to existing pedestrian lighting structures along Broadway Avenue.
            iv.   Provide one (1.0) foot-candle of illumination.
            v.   Shall conform to IDA (International Dark-sky Association) standards to prevent light pollution.
            vi.   Shall be submitted to the ARB as an overall street lighting plan for development or building frontage.
   B.   Pedestrian Circulation, Landscaping and Streetscape Design
      1.   Sidewalks
         a.   Sidewalks will be required along all road frontages.
         b.   Sidewalks located on a section or block with on-street parking shall be at least five (5) feet, but no more than twelve (12) feet in width.
         c.   Sidewalks shall connect to sidewalks on adjacent parcels.
         d.   Use of permeable pavers or pavement is encouraged for sidewalk material, to be approved by the City Engineer.
      2.   Pedestrian Buffer/Tree Lawn: A Pedestrian Buffer/Tree Lawn may be required in order to buffer pedestrians from automobile traffic and to help green the Central Business District in accordance with adopted Streetscape Improvement Plans or Corridor Plans for Broadway Avenue, Libby Road or Lee Road.
         a.   If a buffer area is included by an adopted Plan, property owners shall accommodate such requirements, and may be required to assist in the establishment of this landscaped buffer.
         b.   Maintenance of the pedestrian buffer/tree lawn shall be the responsibility of the property owner. Failure to properly maintain the buffer or tree lawn area shall result in action by the City against the property owner.
         c.   This buffer shall be constructed to encompass existing streetlights, and other above ground public utilities.
         d.   Landscaping. All landscaping plans shall be approved by the Building Commissioner and the Architectural Review Board.
            i.   This buffer shall contain, at minimum, one (1) small tree for every twenty (20) feet of frontage, or one (1) medium tree for every tree for every thirty (30) feet of frontage. Trees may be accommodated by tree grates, tree wells, or tree boxes.
            ii.   The buffer area should also feature a continuous vegetated tree lawn in addition to street trees. This tree lawn shall include only native, salt-and drought-resistant plantings ranging from two (2) inches to two (2) feet in height. A list of appropriate trees and native plants are listed in Section 1282.11 (G).
            iii.   This buffer may also feature raingardens or vegetated bioswales. These bioswales must be approved by the City Engineer. A list of plants to include in a raingarden or bioswale is included in Section 1282.11 (G).
      3.   Pedestrian Amenities:
         a.   City standard benches, trash receptacles and other street furniture shall be installed at regular intervals along Broadway Avenue, Libby and Lee Roads in the Central Business District and shall be located at transit stops and in public outdoor spaces. Such treatments will be adjacent to the front sidewalk or along the building frontage and shall not impede the flow of pedestrian traffic.
         b.   Street furniture and pedestrian amenities shall be included in development plans submitted to the Architectural Review Board.
      4.   The Central Business District will also feature streetscape treatments to help foster a pedestrian-friendly environment. One or several of the following treatments may be required or encouraged to be installed or maintained within the ROW:
         a.   Textured sidewalk ramps.
         b.   Curb Extensions/Sidewalk Bump-outs.
   C.   Green Infrastructure
      The City of Maple Heights strongly encourages the use of green infrastructure throughout the City. The following green infrastructure opportunities are either encouraged or required within the Central Business District:

The Maple Heights City Engineer can provide guidance for the design and planting of raingardens and vegetated bioswales.
      2.   Green parking lots: Parking lot islands and/or parking lot buffers should take the form of raingardens, bioswales, or planter boxes if possible. These include recessed islands rather than traditional raised curb islands.
      3.   Pervious pavement/pavers. Pervious pavers or permeable pavement should be used in pedestrian walkways. Pervious pavers can be used in lieu of concrete or asphalt for driveways and parking lots. Permeable pavement should be avoided anywhere meant for automobiles.
      4.   Light-colored pavement/pavers: Developers should opt for light-colored asphalt, concrete, pervious pavement, or pavers to reduce the urban heat island effect.
      5.   Rooftops: All rooftops must be painted white to reduce the heat island effect, unless green roof technology is utilized.
      6.   Green infrastructure plans must be included in required plans to be submitted to the Architectural Review Board.

      1.   Site features such as dumpsters, mechanical equipment, service entrances, loading zones and outdoor storage shall not be located in the front or side yard.
      2.   All site features shall be screened from view from the public right-of-way. Screening materials shall resemble, to a practical extent, the construction materials of the primary building.
