A copy of the draft ordinance amendment is attached. Background The last several development projects within the City's Business Park, in conjunction with dis- cussions with different developers, have identified that the City's architectural standards are out of harmony with current market construction trends and production terminology. The purpose of this amendment is to clarify and align City design requirements with current market trends and practices and to position Cottage Grove for growth. A review of the architectural standards of other similarly positioned peer communities in the region was conducted and the Cottage Grove ordinance was found to be very similar in scope, if not more restrictive, in a positive context. A copy of this zoning comparative analysis data is attached. Review Schedule Planning Commission: February 27, 2017 Tentative City Council Date: March 15, 2017 60 -Day Review Deadline: N/A Planning Considerations The current ordinance includes a table that identifies four permitted classes of materials and designates what types of construction materials are included in each separate class. The classes rank from one to four with Class 1 materials being the more desirable, higher quality materials with permanence that are utilized within the construction trades. The current construc- tion material table does not separately distinguish between commercial and industrial uses which by nature are similar but not necessarily mirrored in use, design, and construction methods. The proposed amendment includes changes to the ordinance to address this discrepancy as well as several other minor clarifications and modifications. The proposed ordinance language modifications are included in the attached draft ordinance. Planning Staff Report — Planning Case TA2017-009 Architectural Standards — Commercial and Industrial February 27, 2017 Page 2 of 2 Summary The proposed ordinance amendment allows for flexibility in architectural design and construction cost control that will meet the needs of the City and developers when guided by the City's cur- rent professional staff and Council. Recommendation The Planning Commission recommends that the City Council approve the zoning text amend- ment to City Code Title 11-6-13C related to architectural design and construction materials for non-residential structure located in industrial and commercial guided and zoned districts.

ARCHITECTURAL STANDARDS IN BUSINESS DISTRICTS 0§ 152.390 PURPOSE. The purpose of establishing criteria for architectural design and exterior facing materials is to ensure a high standard of development that is compatible with neighboring development and contributes to a community image of permanence, stability, and visual aesthetics, while preventing impermanent construction and use of materials that are unsightly, rapidly deteriorate, contribute to depreciation of neighborhood property values, or cause urban blight. The standards are further intended to ensure coordinated design of building facades, additions and accessory structures in order to prevent visual disharmony. The standards apply in all business districts (B-1, B-2, B-3, B-4, BP, I.) (Ord. 2000-936) 11 § 152.391 GENERAL REQUIREMENTS.

Woodbury Sec. 24-235. - Architecture, nonresidential buildings. (a) Purpose. The purpose of this section is to establish minimum standards for exterior architecture of commercial, office, industrial, institutional and warehouse buildings and to ensure a high quality of development, redevelopment and compatibility with evolving architectural or planning themes that contribute to a community image of quality, visual aesthetics, permanence and stability which are in the best interest of the citizens of the city. These standards are intended to prevent use of materials that are unsightly, deteriorate rapidly, contribute to depreciation of area property values, or cause urban blight. These standards are further intended to ensure coordinated design of building exteriors, additions and accessory structure exteriors in order to prevent visual disharmony, minimize adverse impacts on adjacent properties from buildings which are or may become unsightly, and buildings that detract from the character and appearance of the area. It is not the intent of this division to unduly restrict design freedom when reviewing and approving project architecture in relationship to the proposed land use, site characteristics and interior building layout. However, modifications to the exterior design may be required to promote compatibility with the desired architecture in the immediate vicinity and/or the general architectural character of the area and the city in general. (b) (c) (1) (2) (3) General design concept. Building and/or project designs may be required to modify building materials, colors, details, site plan, landscape plantings, or other features to meet the intent of these architectural standards. Modifications. Projects may be required to utilize building ornamentation features, including but not limited to: columns, arches, parapets, cornices, friezes, canopies, moldings, dentils, corbels, quoins, rustication, vaults, domes, and cupolas. Corporate identity. The intent and purpose of the architectural standards supersede corporate identity designs. When a corporate identity design does not meet the intent and purpose of the architectural standards, the corporate identity design shall be limited to the area immediately adjacent to the main entry and may require modification to meet the intent of the ordinance. Applicability and review. This section shall apply to all commercial, office, institutional and industrial buildings, additions, exterior remodeling and accessory structures, unless different exterior materials are specifically approved.

Industrial and warehouse buildings must use at least two different class I or II materials and be composed of at least 65 percent class I or class II; not more than 35 percent of class III or class IV materials. Not more than ten percent of the building shall be class IV materials. Any nonresidential structure adjacent to an interstate highway, or any multi -tenant office/warehouse or showroom/warehouse or other combinations shall be 65 percent class I materials on primary exteriors. Exterior walls with limited public exposure may use combinations of class II, III or IV materials unless otherwise approved by the city council. Buildings in nonresidential zoning districts that are not office, commercial, industrial or warehouse uses shall conform to the exterior finish materials and proportions of office or commercial buildings unless otherwise approved by the city council as meeting the purpose of this division. The use of class II, III or IV materials shall be distributed throughout the exterior of a building unless the city agrees that materials consolidated on more visible locations provides the most positive architectural appeal to the general public. Expansions of less than 50 percent of the floor area of the existing building may use the same or superior materials as the existing structure. A distinctively different color of brick may be considered as a second class I material. However, minor blended color variations shall not be considered as a separate material. To be counted as a primary material, the product must comprise at least five percent of the exterior wall.

Garage doors, window trim, flashing accent items and the like, shall not constitute required materials that make up the exterior of a building. As viewed from ground levels from all locations, all mechanical equipment located on the roof or around the perimeter of a structure shall be hidden by a raised parapet or with materials comparable and compatible with exterior building materials. a. Q C. d. e. f. A raised parapet or other architectural feature that is an integral part(s) of the building may be required as screening for rooftop mechanical equipment or to soften rooftop views. If shown that rooftop units will be visible, an increased parapet height or additional screening shall be required so that the rooftop equipment is hidden from view. The back of parapets that are visible must be finished with materials and colors compatible with the front of the parapet. Screening for rooftop mechanical equipment shall incorporate similar architectural features of the building and/or be constructed of a material and color compatible with other elements of the building. Screening methods of incidental rooftop equipment deemed unnecessary to be hidden from view by the community development director or a designee shall be approved by the city. Metal cabinets used to enclose and protect rooftop mechanical equipment shall not substitute as screening.
