<br />Each of the city code chapters pertaining to non-residential zoning districts, namely
<br />Commercial and Mixed-Use Districts (i.e., Neighborhood Business, Community
<br />Business, Regional Business, and Community Mixed-Use), Employment Districts (i.e.,
<br />Office/Business Park and Industrial), the Institutional District, and the Parks and
<br />Recreation District, contains a Design Standards section which establishes the following:
<br />“All exterior wall finishes on any building must be one or a combination of the following
<br />materials: face brick, natural or cultured stone, textured pre-cast concrete panels, textured
<br />concrete block, stucco, glass, pre-finished metal, fiberglass or similar materials, or cor-
<br />ten steel (other than unpainted galvanized metal or corrugated materials). Other new
<br />materials of equal quality to those listed may be approved by the Community
<br />Development Department.”
<br />The exclusion of “corrugated” metal has long been in the code, likely as a simple way to
<br />prohibit agricultural “pole barn” type buildings, and the amendment proposed and
<br />discussed in May sought to maintain this prohibition but better distinguish “pole-barn”-
<br />type corrugated metal from more acceptable metal materials. The proposed amendment
<br />was, admittedly, a crude one; rather than accept such an amendment, the Planning
<br />Commission tabled the item, requesting (and offering) some additional effort to create a
<br />worthwhile amendment.
<br />In the end, Planning Division staff has been unable to draft an objective distinction
<br />between acceptable and unacceptable metal finishes for building exteriors and now
<br />proposes a solution based on the design requirements in the City of Wayzata in which
<br />metal of any kind is excluded from the list of allowable exterior materials and allowed
<br />only as an accent material. In this proposal, distinguishing between different kinds of
<br />metal materials is no longer important since it will be limited in its usage.
<br />5.0P ROPOSED Z ONING T EXT C HANGES
<br />Given the above discussion (and that from the Planning Commission on June 5, 2013),
<br />the Planning Division’s present suggestion is to amend the above-quoted Materials
<br />section in §1005.02F (Commercial and Mixed-Use Districts Design Standards),
<br />§1006.02C (Employment Districts Design Standards), §1007.02F (Institutional District
<br />Design Standards, and §1008.02C (Park and Recreation District Design Standards) as
<br />follows:
<br />All exterior wall finishes on any building must be one or a combination of the following
<br />materials: face brick, natural or cultured stone, pre-colored or factory stained or stained
<br />on site textured precast concrete panels, textured concrete block, stucco, glass,
<br />prefinished metal, fiberglass, or similar materials . or cor-ten steel (other than unpainted
<br />galvanized metal or corrugated materials). In addition to the above materials, accent
<br />materials, not exceeding 10% of any exterior building elevation, may include pre-
<br />finished metal, cor-ten steel, copper, premium grade wood with mitered outside
<br />corners (e.g., cedar, redwood, and fir), or fiber cement board . Other materials of
<br />equal quality to those listed,including the use of commercial grade lap-siding in the
<br />Neighborhood Business District , may be approved by the Community Development
<br />Department.
