a) The zones set forth in this Section are defined in the design overlay district map on record with the City Clerk.
b) Architectural Standards. The requirements contained within this Division shall not apply to any structure in the Agricultural, Rural Residential or Park/Open Space districts. It shall apply to all structures used for commercial purposes in Single-Family Residential, Medium Density Residential, and High Density Residential, all structures in the Central Business, Commercial, and Industrial Districts.
These standards are intended to ensure coordinated design of new and existing building exteriors, including additions and accessory structures, in order to prevent visual disharmony; minimize adverse impacts on adjacent properties from buildings which detract from the character and appearance of the district; and aid in improving the overall economic viability of the district. These standards are further intended to prevent use of materials that are unsightly, subject to rapid deterioration or which contribute to depreciation of property values or cause urban blight. It is not the intent of this Section to unduly restrict design freedom when reviewing and approving project architecture in relationship to the proposed land use, site characteristics and interior building layout. While the City of North Branch has not established a theme or particular style of architecture that must be adhered to, a general goal of creating a professional appearance with architectural appeal associated with a small city atmosphere is desired within the City of North Branch.
(1) Architectural plans shall be prepared by an architect or other qualified person (as determined by the Zoning Administrator) and shall show the following:
(a) Elevations of all sides of the building. (b) Type and color of exterior building materials. (c) Typical floor plans. (d) Dimensions of all structures.
