10 City of Lake eLmo - Design guiDeLines & stanDarDs - REVISED 2-2-22 <br />HIgH densIT y resIdenTIal developmenT <br />g.Detached garages shall be architecturally con- <br />sistent with the principal structure. <br />h.Finished exterior materials shall be applied <br />to all wall facades above 18 inches from the <br />finished grade line, where unfinished exterior <br />foundation may be visible. <br />i.Ground level of multi-family structures should <br />be distinguished architecturally from upper <br />levels to provide human-scale elements for pe- <br />destrians. <br />j.Living space below the main building level, <br />such as a walkout structure, may not be visible <br />from the front side of the structure facing the <br />main public street. <br />k.Split entry type structures are discouraged. <br />l.Where individual units face a public street, <br />each unit should shall be designed with a <br />walkway from the sidewalk to the front entry <br />feature. <br />m.Entryways to individual units should shall <br />contain an entryway feature, such as a porch <br />or portico. <br />Building Materials <br />Goal: To offer a variety of attractive and quality build- <br />ing materials that will shape the identity and <br />visual interest of residential development in Lake <br />Elmo. <br />a.All structure facades should utilize multiple <br />building materials. <br />b.Changes in facade building materials should <br />occur at clean horizontal and vertical separa- <br />tions, such as at building levels or architectural <br />features. <br />c.Siding materials should emphasize horizontal lines <br />to reduce the appearance of height and mass. <br />d.Multiple facade colors are encouraged as long <br />as they are balanced and consistent. <br />e.Primary building materials for residential struc- <br />tures should shall include brick, finished <br />wood, fiber cement, stone, quality metals, <br />glass, cast-stone, or pre-cast concrete panels <br />with aggregate, banding, testuring, or other <br />similar decorative finish. <br />f.Exposed exterior building materials such as <br />brick, stone, wood, or stucco should be au- <br />thentic. Simulated materials may also be used <br />if demonstrated to be of high quality and ap- <br />proved by the City. <br />g.Materials which are prohibited as the primary <br />facade material include the following: <br />• Vinyl siding <br />• Unpainted galvanized metal <br />•Corrugated metal, plastic, or fiberglass <br />• Plain, unpainted, or painted concrete block <br />• Prefabricated concrete panels <br />h.Roofing materials should consist of composition <br />shingles, wood shakes, or clay or stone tiles. <br />Metal used as a roofing material must incorpo- <br />rate ribs or standing seams to be acceptable. <br />Scale and Mass <br />Goal: To establish parameters for building horizon- <br />tally and vertically with a human scale in mind. <br />a.Building volume should be broken up with re- <br />cesses and projections such as balconies, bay <br />windows, dormers, porches, and other features <br />that provide variation and identity. <br />b.Mass should be reduced through facade artic- <br />ulation, breaking up the wall area into smaller <br />sections. <br />c.Architectural elements, such as dormers, deco- <br />rative windows and trim, porch details, decora- <br />tive shutters, and wainscoting, can reduce the <br />appearance of bulk and mass by providing vi- <br />sual interest. <br />d.Building mass should be broken up with mul- <br />tiple roof and ridgelines perpendicular with one <br />another. <br />e.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 />f.Scale should be reduced by utilizing “step- <br />down” methods towards the public street. <br />Porches, entries, window-bays or bump-out are <br />effective in this regard. <br />Building Mass is reduced by breaking the building up into <br />smaller sections and “stepping-back” levels above the <br />ground floor.
