Below is a more detailed description of the improvements planned for Phase I of the Historic Park City Infrastructure Improvements.

Terigo Walkway
The Terigo Plaza is meant to be more creative and unique to set it apart from a traditional and historic design that is intended for Main Street. It includes interpretive elements intended to call attention to Park City, such as curved “foot prints” in the paving representing the mining cart of the past, with ski tracks of the present. The new design also adds greater pedestrian connection from China Bridge to Main Street by replacing the stairs and adding an ADA accessible ramp. The improvements will also include additional safety lighting and connection across Swede Alley.

7th Street from Park Avenue to Summit Watch Entrance
7th Street improvements are designed to create greater east – west pedestrian movement, beginning at the bottom of the ski bridge on Park Ave. across to Main Street and beyond. Connection into Summit Watch is a primary focus and improvements within the Summit Watch entry are the responsibility of the property owner. Because the intersection of 7th and Main is also used as event staging (i.e.Tour of Utah and Silly market) the proposed design replaces the asphalt with vehicular pavers, so that it can be transformed from a street to plaza. Power and lighting improvements will facilitate such needs as well. East – west sidewalks will be improved but secondary to Main Street.

Pedestrian Paving
Historically Main Street had wood plank sidewalks that transitioned into concrete sidewalks decades ago which exists today. A logical progression of history would allow a more durable material that is conservatively stated as to not detract from the beauty of the historic buildings that face Main Street. Each of the options considered to date have Granite Pavers. While analyzing the pavers that have historically been used in Park City the design group noted an overall deterioration of concrete and clay pavers. Granite paving was recommended as a more durable material that would bring a quality experience for the users of Main Street as long as the colors were conservative (gray/earth tones) allowing the historic buildings to be the focus of user’s attention. Granite also provides a greater sense of place and a quality environment.  Granite has a life span of at least 50 years compared to concrete that will start showing wear within the first couple of years of installation. Granite pavers will be dry set on sand allowing for easy maintenance should a paver get chipped or damaged.  The Council specified that the granite must be sourced from within the U.S.

The “look and feel” of the granite is also very important. The longevity of the granite adds to the appearance. Although granite will require some resetting it will maintain its looks throughout its lifespan which may be well beyond 50 years. As mentioned above the concrete will crack and heave detracting from the look, feel and even function of the walking surface.

The City Council gave support for the granite pavers is based primarily on design and look and feel, and sustainable design considerations that are balanced with budget impact.  Based on three independent studies the granite curb has been found to be more cost effective than concrete curb. The granite curb while having a higher initial cost outlasts concrete by a minimum of 2.5 times. Concrete curb (especially high back) does not hold up to the damage caused by snow plows and only has a 10 year lifespan. Even after a few years the snow plow damage is evident and does not look good.

Granite paving is similar to the granite curb in that the product will last 50+ years. Granite curb and paving is very sustainable in that it is reusable whereas concrete is only recyclable although much will wind up in the landfill when any subsurface work is performed. Granite can also be reset if there is any heaving or settling whereas the concrete either needs to be ground down, affecting the appearance, or the concrete needs to be replaced if badly cracked.

The concrete band around the granite pavers will also help at the transition to some of the doorways. Because the banding will be tied to the slab under the granite heaving between the pavement types should be minimized. Also the banding will be in smaller jointed squares which should reduce cracking.
