A.
Purpose. The purpose of this section is to regulate the design and materials used for the exterior of buildings and structures within the City so as to maintain and enhance the attractiveness and values of property in the community. This article is further intended to support the creation of a pedestrian-oriented urban environment that emphasizes architectural and urban design principles of human scale and visual interest. Additionally, this article is intended to ensure the development of structures that maintain a long-lasting appearance; withstand the effects of time and exposure to the elements; resist damage in areas with high vehicular and pedestrian traffic and in areas where larger equipment that could cause damage is commonly used; that maintain a consistent character of development based on land use and zoning district particular to each development; and that contribute to the long-term economic and social vitality of the City of Jefferson.
B.

§ 300-7.50 Special areas.
Downtown Historic Mixed-Use District (DHMU) Design Standards. See § 300-2.33 for additional requirements for this district.
A.
Purpose. This district is intended to implement the urban design recommendations of the Comprehensive Plan, by preserving and enhancing the historical quality of the downtown, and by attaining a consistent visually pleasing image for the downtown area, as defined by the mapped boundaries of the Downtown Historic Mixed-Use District.
B.
Applicability. The regulations of this section shall apply to new development and changes to the exterior of any building within the mapped boundaries of the Downtown Historic Mixed-Use District.
C.
Review and approval.
(1)
There are three categories of review in this district:
(a)
Renovation review (renovation of the exterior appearance of a property such as repainting, re-roofing, residing or replacing with identical colors, finishes, and materials).
(b)
Design alteration review (change only in the exterior appearance of a nonresidential or multifamily property such as painting, roofing, siding, architectural component substitution, fencing, paving, or signage).
(c)
Project review (modification to the physical configuration of a property such as the erection of a new building, the demolition of an existing building, or the addition or removal of bulk to an existing building).
(2)
Plan Commission review and approval may be required. The three categories and procedural requirements for review and approval are described fully in § 300-10.44.
(4)
Designated historic structures. These regulations are separate and in addition to requirements related to changes to local, state, and national landmarks and properties, and as regulated by the Historic Preservation Ordinance (Chapter 151 of the City of Jefferson Municipal Code). Prior to taking action, the Plan Commission shall consult with the Historic Preservation Commission for all properties designated as historic, contributing to a historic district, or considered by a study or survey to be eligible for listing on a local, state, or national register.
D.
Design theme. The design theme for the Downtown Historic Mixed-Use District is based on its historical, pedestrian-oriented development pattern that incorporates retail, residential, and institutional uses. Building orientation and character includes minimum setbacks at the edge of the sidewalk, multi-story structures, use of alleys for access, and on-street or other off-site parking. The design theme is characterized by a variety of architectural styles popular at the time, including Italianate, Romanesque, and Neoclassical, in a two- or three-story format with office, storage, or residential located over commercial. The facades of these buildings have a traditional main street storefront appearance, are relatively small in scale, have street yard and side yard setbacks of zero feet, have prominent horizontal and vertical patterns formed by regularly spaced window and door openings, detailed cornice designs, rich detailing in masonry coursing, window detailing and ornamentation, and are predominately brick, stone, or wood. Exterior building materials are of high quality. Exterior appurtenances are minimal. Exterior colors are harmonious, simple, and muted. Exterior signage blends, rather than contrasts, with buildings in terms of coloring (complementary to building), location (on-building), size (small), and number (few).
