Design Criteria Before issuance of a site development permit for each phase of a project, if any, the developer must submit architectural elevations in the form of a "Plan Book" for typical structures for review and approval by the Director. At a minimum, the "Plan Book" must include: allowable building elevations; design criteria for entries, porches, doors, windows, dormers, columns, cornices, rakes, garages, roofs, landscaping, fencing, and retaining walls; exterior colors and materials; and other pertinent information. All structures must be constructed in accordance with the approved "Plan Book." This "Plan Book" becomes a binding restriction on all structures within the development and may be amended or supplemented only by approval of the Director.
Portions of lots and buildings along external public streets must include the following in areas visible from such streets:
These requirements apply in addition to those of Sec. 201-3 (General Architectural Standards) and are intended to continue the architectural theme that is presented on the front elevation of the house/building to other facades exposed to frequent public view.

All grassed areas must be sodded with a drought-resistant grass, such as Bermuda, Centipede, Zoysia, or other species, as approved by the Director.
Concept Plan Review Required All rezoning applications to a residential district must be accompanied by a concept plan in compliance with this subsection. The purpose concept plan review is to encourage logic, imagination, innovation, and variety in the design process and ensure the soundness of the proposed development and its compatibility with the surrounding area. The Director will review plans for compliance with concept plan review criteria and this UDO. The recommendations of both the Director and the Planning Commission will be transmitted to the City Council. Through the rezoning process, the City Council may condition approval of a rezoning request to a specific concept plan or require an additional future site plan review by the Planning Commission and City Council.
The following exhibits must be prepared by registered design professionals, such as engineers, architects or landscape architects, and submitted to the Department. No application for an R-TH district may be accepted for processing without these required exhibits:
