§ 153.088 CORRIDOR DEVELOPMENT REQUIREMENTS.
   (A)   Lot size requirements.
      (1)   Minimum lot size. All lots within the Overlay Zone shall contain a minimum area of five acres, except those classified as a "commercial outlot" below.
      (2)   Pre-existing undersized lot. If a lot was recorded prior to the effective date of this subchapter, and said lot does not contain the minimum area required by this section, said undersized lot may be used for any use permitted in the Overlay Zone provided that:
         (a)   On or before the effective date of this subchapter, the undersized lot met the requirements for minimum lot size then in effect for a lot in the underlying zoning district(s); and
         (b)   All other applicable regulations of the Overlay Zone can be met.
      (3)   Commercial outlot. Commercial outlots shall be permitted as part of a commercial/retail shopping project within the Overlay Zone provided that:
         (a)   The minimum size of the outlot is 21,780 square feet;
         (b)   The outlot is an integral part of the commercial/retail project with respect to traffic circulation, development plan requirements, landscaping, architecture, and signage; and
         (c)   The outlet does not have direct access to a corridor street.
   (B)   Setback requirements. All setbacks are measured from the right-of-way of the adjacent roadway(s). For purposes of this section, corner lots have two front yards and two side yards.
      (1)   Minimum front yard setback:
         (a)   Corridor street: 90 feet.
         (b)   Interior street: 40 feet.
      (2)   Minimum side yard setback:
         (a)   Commercial outlot: 30 feet.
         (b)   Residential lot: 30 feet.
         (c)   All other lots: 45 feet.
      (3)   Minimum rear yard setback: 45 feet.
         (a)   Commercial outlot: 20 feet.
         (b)   Residential lot: 20 feet.
         (c)   All other lots: 30 feet.
   (C)   Lot coverage requirements. No more than 40% of the lot area may be covered by impervious surfaces, including structures, parking, and other hard surfaces unless one or more of the following green construction methods are utilized:
      (1)   Green roof construction. All building surface area under green roof construction is not counted towards the impervious surface cover calculations, and therefore increases potential square footage for construction.
      (2)   Parking lot and other surfaced elements. Natural filtration of water through soil is the simplest way to control the volume of run-off and pollutants associated with run-off, which is a direct advantage of permeable pavement. Therefore, all surface areas constructed with permeable pavement materials, including porous asphalt, porous concrete, plastic grid systems, or block pavers are not counted towards the impervious surface cover calculations and therefore increase potential square footage of impervious construction.
   (D)   Architectural design requirements. In reviewing the architectural design of a building(s) proposed to be built in the Overlay Zone, factors to be considered by the Overlay Committee and the Commission shall include but are not limited to:
      (1)   Scale and proportion;
      (2)   Suitability of building materials, including color;
      (3)   Design in relation to surrounding buildings;
      (4)   Design in relation to topography of the site;
      (5)   Design in relation to proposed landscaping;
      (6)   Aesthetics of the proposed building, including color; and
      (7)   Context.
   (E)   Context and design standards.
      (1)   Relationship of building to site.
         (a)   The site shall be planned to accomplish a desirable transition with the streetscape and to provide for adequate landscaping, safe pedestrian movement, and parking areas.
         (b)   The height and scale of each building shall be compatible with its site.
         (c)   Newly-installed utility services and service revisions necessitated by exterior alterations shall be underground.
      (2)   Relationship of buildings and site to adjoining area.
         (a)   Adjacent buildings of different architectural styles shall be made compatible by such means as screening, setbacks, sight breaks, and materials.
         (b)   Attractive landscaping transition to adjoining properties shall be provided.
         (c)   Harmony in texture, lines, and masses is required. Monotony shall be avoided.
      (3)   Building design.
         (a)   Architectural style is not restricted. Evaluation of the appearance of a project shall be based on the quality of its design and relationship to surroundings.
         (b)   Buildings shall have a good scale and be in harmonious conformance with permanent, neighboring development.
            1.   Materials shall have appropriate architectural character and shall be selected for harmony of the building with adjacent buildings.
            2.   Materials shall be selected for suitability to the type of buildings and the design in which they are used. Building facades which are visible from public ways shall all have the same materials or those that are architecturally harmonious.
            3.   Facade articulation shall be no less than 75 feet for all sides of the structure(s).
   (F)   Landscaping. A landscaping plan shall be submitted as part of the application. Said plan shall be drawn to scale, including dimensions and distances, shall delineate all existing and proposed structures, private parking areas, walks, ramps for handicapped, terraces, driveways, signs, lighting, steps and similar structures, and shall delineate the location, size, and description of all landscape materials to be used. Landscape treatment of plazas, driveways, paths, and service and parking areas shall be designed in an integral and coordinated fashion with the entire lot. Whenever possible, existing trees shall be conserved and incorporated in the landscaping plan. All landscaping required by the approved plan shall be installed within six months of the first occupancy of the building on the lot.
      (1)   Total landscaping. A minimum of 15% of the lot shall be landscaped, which includes the greenbelt plantings, parking lot landscaping, building perimeter plantings, and property perimeter plantings.
      (2)   Greenbelt plantings. Greenbelts shall be provided along each property frontage and be suitably landscaped and otherwise unoccupied except for steps, walks, terraces, driveways, lighting standards, signs, and other similar structures (excluding private parking areas). Mounding and other treatments are to be especially encouraged in this greenbelt.
         (a)   Corridor street greenbelt. Thirty feet wide, measured along right-of-way. One shade tree and four large shrubs shall be provided for every 50 linear feet.
         (b)   Interior street greenbelt. Fifteen feet wide, measured along right-of-way. One shade tree and ten medium shrubs every 50 linear feet.
      (3)   Parking lot landscaping. All parking lot landscaping shall be of a quality to improve and enhance the site and the surrounding area. Effective use of mounding and topography is encouraged. Landscaping and planting areas shall be reasonably dispersed throughout the parking areas.
         (a)   Perimeter planting. There shall be a perimeter landscaping strip, four feet wide, located along the side of any private parking area which abuts any side or rear property line. One shade tree for each 50 lineal feet shall be incorporated into the landscaping strip.
         (b)   Interior planting. Not less than 8% of all parking areas shall be landscaped. For the purposes of this requirement, plantings in the greenbelts and parking lot perimeter plantings shall not be included.
      (4)   Building perimeter plantings. A planting area equal to an area measuring an average of ten feet in depth and extending along the entirety of each wall of the building shall be installed adjacent to the building. Sidewalks may be permitted in these areas,
but shall not occupy more than 50% of the entire area on any side of the building. If an approach driveway cuts into a planting area adjacent to the building, additional planting area equal to the area displaced by the driveway shall be added to the building perimeter planting. These perimeter planting areas need not be rectangular in shape as long as the required total area is landscaped and dispersed on at least three different sides of the building.
      (5)   Property perimeter plantings. A property perimeter planting area shall be a minimum of five feet in width and shall be provided along the common perimeter of the property except for frontage areas. Perimeter planting areas are not in addition to the required yard areas. Perimeter property plantings shall include one shade tree and four medium shrubs every 50 feet.
   (G)   Parking requirements. Parking is to be discouraged between the greenbelt and the front line of the building when other suitable areas exist on the property. Total parking space and loading berth requirements shall be those of the underlying zoning district.
   (H)   Lighting requirements. In reviewing the lighting plan for a lot proposed to be developed in the Overlay Zone, factors to be considered by the Commission shall include but are not limited to:
      (1)   Safety provided by the lighting;
      (2)   Security provided by the lighting;
      (3)   Possible light spillage or glare into adjoining properties;
      (4)   Attractiveness of the lighting standards and their compatibility with the overall treatment of the property;
      (5)   Height and placement of lighting standards considering the use.
   (I)   Signage standards.
      (1)   Design. Signage shall be designed as an integral part of the architectural and landscaping plans. The colors, materials, and style of signage shall be architecturally compatible and accentuate the buildings and landscaping on the site.
      (2)   Location. Signs shall not be placed within the greenbelt areas.
      (3)   Wall signs. Wall sign area shall not exceed 15% of the total wall area on which it is placed.
      (4)   Free-standing signs. One sign per business shall be permitted and the sharing of signs is encouraged and at the discretion of the Plan Commission. Free-standing signs shall not exceed ten feet in height or 200 square feet in area. Free-standing signs shall be no closer than 300 feet to another freestanding sign.
      (5)   Coordinated Sign Plan. Developments that submit a coordinated sign plan at the time of overlay zone review submittal shall be allowed a 20% increase in permitted sign area. Said plan shall indicate the size, design, and anticipated placement of all signs on the site.
   (J)   Access. Having numerous entrances to lots from the corridor streets in the Overlay Zone is inconsistent with the intent of this section. Access roads and frontage roads shall be constructed whenever possible. No entrances shall be permitted directly from the corridor streets. Access roads to contiguous lots shall be coordinated so as to form one main access road to those adjoining developments. These roads should be designed so as to funnel traffic onto major arterial or collector roads.
   (K)   Other requirements.
      (1)   No outside storage, unenclosed storage of refuse (whether in containers or not) or display of merchandise shall be permitted on any lot.
      (2)   Screening of trash receptacles, recyclable receptacles, refuse areas, and outside material/equipment storage. No outside, unenclosed storage of refuse, materials, or equipment (whether or not in containers) shall be permitted on any lot. All refuse, recyclables, materials, and equipment shall be contained within an area enclosed on all sides by a fence, wall, mound, or similar means of enclosure, even when inside a dumpster, compactor, or other refuse container. The enclosure does not have to have a roof. The sides of the enclosure shall be a minimum of six feet or at least two feet taller than the container, dumpster, compactor, or assemblage of material that is being screened from view, whichever height is greater. All sides of the enclosure structure, including doors or gates, shall be opaque.
      (3)   All commercial and industrial operation on any lot in the Overlay Zone shall be contained within a building.
