In the business park zoning district, the following are acceptable building materials and finishes: 1. Brick. 2. Natural or cut stone. 3. Integrally colored split face (rock face), burnished, or glazed concrete masonry unit (excluding plain or painted). 4. Integrally colored and exposed aggregate precast concrete panels (excluding single-T or double-T panels, plain, uncolored, or raked finish) or specially designed, cast-in-place concrete. 5. Glass, architectural metal, fiberglass and aluminum, provided such panels are factory fabricated and finished with a durable nonfade surface and their fasteners are of acorrosion-resistant design. 6. Stucco, E.LF.S., and other cementitious coating. 7. Wood, provided the surfaces are finished for exterior use or wood of proven exterior durability is used, such as cedar, redwood, and/or cypress. 8. Other materials determined as acceptable by the planning department. c. Major exterior surfaces that are adjacent to any public street, public trail/path, or adjacent residentially zoned properties shall be of one of the acceptable materials and shall be combined with at least 30 percent of one or more acceptable materials, or with 40 percent punched openings, with or without glass (or as much as allowed by the Uniform Building Code, whichever is less), neither of which are to be concentrated in any one location, unless to accentuate a design feature. Major exterior surfaces that are visible from but not adjacent to any public street, public trail/path, or adjacent residentially zoned properties shall be considered transition walls and may have less than the 30 percent combination or less than 40 percent punched openings, but either shall not be reduced to zero percent). Reductions below 20 percent shall require staff approval. Such walls shall be screened from view with additional landscaping. The requirement to have at least 30 percent of one or more acceptable materials shallnot apply to the loading dock wall. d.
