The architecture of any new construction within the PUD shall build on and reinforce the historic context of the existing building or the surrounding industrial area to create a development identity that recognizes the history and incorporates the forms and elements typical of the original use of the site as a railroad repair yard. Materials should be substantial in character, high quality, durable, and maintain their appearance over a prolonged time. Use of natural materials is encouraged, composite materials such as fiber cement and wood composites are appropriate substitutions. Vinyl siding is not allowed. Changes in materials should be aligned with changes in plan or roof form to emphasize these changes in building mass. Masonry materials shall start and stop at changes in wall plane or wrap structural elements to give authenticity to the material. Fenestration (door and window openings) shall be sized to the scale of the building and be compatible to the historic context. Trim and structural elements such as posts or columns shall be sized to the scale of the building and detailed appropriately to the style. Specific architecture for all additions or new buildings shall be evaluated as part of the site plan or permitted conditional use review and approval process.
A. Principal Building (Historically A Rail Car Maintenance Building): All exterior modifications, building additions or attached accessory structures to the former rail car repair building shall be compatible with the historic character of the existing building. Design for new construction should incorporate the form, scale, elements and detailing typical to an 1890s railyard. Repair and/or replacement shall be of like kind or revert back to the original historic appearance if not replacing original material. It is strongly recommended that any alterations or additions be easily reversible or follow The Secretary of the Interior's Standards for Rehabilitation by the National Park Service.
B. Detached Garage Buildings Or Other New Construction: Building designs should incorporate the form, scale, elements and detailing typical of late 1800s to early 1900s industrial buildings. Appropriate massing includes one story and story and a half structures. Roofs shall be pitched, either gable or shed as typical for the period. Building design should give the appearance of brick, cast concrete or concrete masonry units for the exposed foundation, wood siding, sheet metal siding or brick veneer for the remainder of the exterior walls.
C. Decorative Graphics Or Artwork: Decorative graphics or artwork will not be considered signage if not specific to the activities or tenants within the development. Decorative graphics or artwork, not commercial in nature, may be approved through a minor modification to a site plan application and process. (Ord. 2206, 3-20-2017)
