16 City of Lake eLmo - Design guiDeLines & stanDarDs - REVISED 2-2-22 <br />CommerCIal developmenT <br />d.Minimizing continuous expanses of wall <br />through facade articulation, recession and pro- <br />jection is encouraged. <br />e.Structures that are oriented towards the public <br />street are encouraged to provide multiple ac- <br />cess points or entrances if the parking area is <br />located to the rear of the structure. <br />f.Architects and builders are encouraged to in- <br />corporate topographical features into the form <br />of the structure when possible, utilizing natural <br />grades to create unique design. <br />Building Materials <br />Goal: To promote quality development through du- <br />rability and visual aesthetics, thereby supporting <br />district identity. <br />a.High-quality and durable materials should be <br />used in street facing facades. <br />b.Primary building materials for commercial <br />structures should include brick, finished wood, <br />stone, cast stone, or pre-cast concrete panels <br />with exposed aggregate, banding, texturing, or <br />other similar decorative finish treatment. <br />c.High quality synthetic materials that adequate- <br />ly duplicate natural materials may be accept- <br />able if approved by the City, including, but not <br />limited to, thin brick, hardi plank, decorative <br />concrete masonry, and other materials. <br />d.The following building materials are not allowed <br />to be used as the primary facade for commer- <br />cial development: <br />•Unpainted galvanized metal <br />•Unfinished “green-treated” lumber <br />•Unfinished wood <br />•Plain or unpainted concrete <br />•Painted concrete block may be used on <br />the rear of the building or sides not visible <br />from the public right of way. <br />•Vinyl siding <br />e.Facade colors should reflect subtle earth <br />tones. However, other primary facade colors <br />will be considered by the Review Authority. Ac- <br />cent materials should complement the colors <br />of the primary facade. <br />Scale and Mass <br />Goal: To establish standards for building with a hu- <br />man scale in mind. <br />a.Buildings should be broken down into smaller <br />parts to avoid monotonous or continuous de- <br />sign and the appearance of mass. <br />b.Exterior design that provides the appearance <br />of multiple structures is encouraged to reduce <br />scale and minimize mass. <br />c.Building mass should be broken up with mul- <br />tiple roof and ridgelines perpendicular with one <br />another. <br />d.Structures of two-stories or higher should have <br />articulated facades to minimize the appear- <br />ance of mass, as well as multiple roof lines <br />with corresponding gables. <br />e.Scale should be reduced by utilizing “step- <br />down” methods towards the public street. En- <br />tries and other bump out features are effective <br />in this regard. <br />Parapets of varying heights add architectural interest and <br />accentuate building entries. <br />High quality and durable building materials add aesthetic <br />value and create a more attractive environment.
