A.   Regulating Plan: The form based development standards in the following sections are intended to shape development and redevelopment in certain districts of the City. The standards are designed to promote the creation of economically vital, mixed use, pedestrian friendly districts. The form based standards describe required development patterns, building and frontage types, and parking locations and treatments. The standards are organized in sections with each section defining building and site development conditions affecting the quality of the built environment and ensuring projects are consistent with the goals, objectives, and guidelines in the downtown and riverfront crossings master plan and the central district plan.
   B.   Subdistricts:
      1.   The Riverfront Crossings District is divided into subdistricts, which are listed below with the corresponding zoning map symbol.
         a.   South Downtown Subdistrict (RFC-SD).
         b.   University Subdistrict (RFC-U).
         c.   Central Crossings Subdistrict (RFC-CX).
         d.   Gilbert Subdistrict (RFC-G).
         e.   Park Subdistrict (RFC-P).

      2.   The Eastside Mixed Use District, which is located in the Central Planning District is designated with the following zoning map symbol:
         a.   Eastside Mixed Use District (EMU).
   C.   Applicability: All development within the Riverfront Crossings District and Eastside Mixed Use District as designated on the zoning map shall be subject to the provisions of this article and to the use regulations and site development standards contained in chapters 4 and 5 of this title and, if applicable, the overlay zone provision of chapter 3 of this title. In the case of any inconsistency or conflict between the provisions of this article, the provision that is more specific to the situation will control. When regulations are equally specific or when it is unclear which regulation to apply, the more restrictive provision will control.
For purposes of this article, "grade" shall be defined as the average point of elevation of the finished surface of the ground, paving, or sidewalk within the area between the building and the streetside property line(s), or when the streetside property line is more than five feet (5') from the building, between the building and a line five feet (5') from the building. Grade shall be calculated measuring the level of the surface of the ground at least every twenty feet (20') along the entire frontage of the property. If due to unavoidable site conditions, the finished surface of the ground has been or is proposed to be raised by adding fill, the slope of the fill within twenty feet (20') of the building shall not exceed four horizontal to one vertical (4:1) or twenty five percent (25%). Any story that has more than three feet (3') of its floor to ceiling height above grade along one (1) or more frontages shall be counted as a story for purposes of measuring height. Streetside property lines shall include those abutting approved pedestrian streets. (Ord. 16-4675, 9-20-2016)
   D.   Design Review: Any exterior alterations to, additions to, or new construction of buildings and structures, or alterations or additions to site development, including, but not limited to, parking areas, landscaping, screening, lighting, and access on property zoned to a Riverfront Crossings or Eastside Mixed Use designation shall be subject to design review. Design review shall be conducted by the Form Based Code Committee (FBC Committee), as designated by the City Manager. The FBC Committee shall review the proposed development for compliance with the applicable provisions of this article and the goals and objectives of the adopted downtown and riverfront crossings master plan and central district plan.
