Silverthorne: Designed for Locals; Experienced by Everyone As a gateway to the Rocky Mountains, downtown Silverthorne is a magnetic place recognized for its public art, local flavor, and walkable amenities. The Blackbox Theatre, unique riverwalk, festival bridge, and pedestrian oriented streets create a destination for visitors and residents. The intimate downtown scale naturally forms a sense of place. Downtown Silverthorne’s design reflects the beauty of its natural setting.
5
Context This Chapter will provide some information that will proceed and introduce where the town of Silverthorne is located and identify its surrounding cities. It will also give some information on the location of the Blue River and parcel locations.

Context Every Spring at The University of Colorado at Boulder (CU Boulder), students are required to enroll in a Praxis Class during their Junior Years. The Praxis Class is designed to give students hands on design experience through application of their skill sets in a real world design project. This Spring 2016, John Lanterman offered a Praxis Studio focused on rehabilitating Downtown Silverthorne. By working directly with the city planning board in Silverthorne, the students enrolled were able to participate in the rehabilitation by designing a new set design guidelines for the downtown area. The design guidelines include urban design and landscape master plans, design drawings for a new pedestrian bridge and plaza, and design options for city blocks in downtown Silverthorne.

Overall there is a variety of ways to identify the proposed parking. It will wither be considered On-street parking or interior parking. One thing that needs to be established is that interior parking, apart from the actual parking garage, will be residential parking and allow access for the service vehicles. All other retail and public parking will be found On-street. As a whole there will be 571 Residential units and 1,749 parking spaces. This accounts for the space that is being proposed for the locations of the Transportation Hub/ Parking garage.

Background According to out research and gathered data, we know that there is a approximately a 60’ ROW on each street, not including Highway 9 and 3rd Street. On Highway 9 there was a ROW of 162’, and 3rd Street has a ROW of 100’. With those numbers we were able to gather individual block square footage incorporate the proposed design and calculated a maximum number of possible space for parking for each land use. For Residential there is a total of 48,4509sf and 688 parking. For Commercial uses there is a total of 192,600sf and 572 parking spaces. And for Industrial uses there is a total of 69,200sf 138 designated parking spaces. Overall we worked with 746,309sf and provided 1,398 parking for the entire downtown. This numbers include parking of a possible parking garage that will be located south of 3rd street and west of Adams Avenue.

Master Plan The Master Plan for Silverthorne is a comprehensive illustration of the proposal for the downtown core. With this, we have incorporated the street designs and layouts, the buildings for the ODI block, and the interventions by the landscape team. This was made through a collaboration between all three teams and compiled in a mix of PhotoShop and Illustrator. This illustration features the detailed riverwalk design from the landscape team and each building developed by the architecture team. This was based on the line work from the sketchup file created by Patrick in order to ensure accuracy for location and scale of buildings, streets, etc. The Master Plan was created in order to give a brief overview of the site and our intervention. This is used as a tool to help establish the project and ground the client in the project. It shows our thoughtfulness and consideration to the site as we show how it blends into the surrounding areas of Silverthorne. Further, the Master Plan gives the viewer an idea as to what is going on in our design and helps to segue into more detailed information about the project.

Street Details This chapter will contain many different streetscape and details of the Main Core streets of Silverthorne. It will contain specific details of 3rd Street, 4th Street, 5th Street, 6th Street, Brian Avenue, Adams Avenue, Highway 9 , and Rainbow Road. I will explain the circulation, surrounding zoning and introduce brief details of buildings and connections to the Festival Bridge.

Precedents There are many different aspects that we gathered from different locations to fit into the identity of Silverthorne. For example, For Rainbow Drive, our precedent is a condominium project in Crested Butte, CO. We found this precedent to be interesting and applicable to Silverthorne because of its size, form, and materiality. It reflects what we feel is appropriate for this area as we are looking to introduce high density residential structures into the neighborhood given the proximity of this area to the rec center and the surrounding residential neighborhoods. For our parking district, we have looked to Belmar for ideas. We were familiar with some of the ideas they introduced into their parking structure and so we have decided to expand upon those ideas and shape them to work with the rest of the town and the rest of our plan. With construction of the Black Box Theatre now underway, we have decided to introduce small artist studios on the first floor of the parking structure which will help expand upon the arts culture of the town as well as introduce store fronts along the street to help keep people on the street and keep pedestrians circulating throughout the area. On the periphery of the downtown core, we knew we needed to be sensitive as the area transitions from mixed use to residential. Along Brian Street we looked to the Holiday neighborhood in Boulder as a precedent. This is a high density residential area that also incorporates work/lived spaces. These allow expansion of the downtown area to more commercial as the town fills out.

Gateway This section is a brief introduction of what may be considered to be the entry point of Silverthorne. it incorporates a design for and arch that will become the ceremonial and icon of the town.
34
35
Gateway The Gateway Arch in Silverthorne is inspired by the rustic lifestyle of Anglers fishing along the Blue River. Located West of the Highway 9- Rainbow Drive intersection the metal arch stretches 200â&#x20AC;&#x2122; feet perpendicularly across Highway 9, towering 50 feet into the air pedestrians and automotive travelers are welcomed into the new downtown through a whole new view. At the ground level pedestrians are able to touch, see and experience how the arch is built into the bridge crossing Highway 9. After removing both planters from the center and exterior of the bridge pedestrians will be able to view the Blue River that much closer, to watch the anglers fight for the catch of the day to enjoying the sounds of the river as it flows down through town.

37
Blue River Walk This chapter will contains specifics details regarding the Blue River Walk and its connection to the natural landscape, as well as some design aspects of the Festival Bridge and the Plaza that will connect with 4th Street.

The Master Plan illustrates the Blue Riverwalk future development including the Black Box Theater and proposed site improvements including the Festival Bridge, Festival Plaza, multiple access points to the river, and a Community Garden.

When many people enter the town of Silverthorne they may not see much. They may notice the outlet malls, the gas station, or maybe the fast food, but they fail to see something that all the Silverthorne locals see every day. They see opportunity to give their town it’s own unique identity. We began to foster this identity through a series of landscape design ideas. From a curving wall that invites pedestrians to sit, mimicking the famous blue river, to an extraordinary bridge which invites tourists and locals alike into an elegant plaza guiding them down a renovated 3rd street, and ending near the Black Box theatre where nature and civilization collide in a well thought out park with river access. Silverthorne will soon be known throughout Colorado, the United States, and possible even the world, for the famous identity it will soon have.

This page is filled with sections to give you an idea of the experiences that you may have when walking through the design of the Blue River Walk. We used some precedents, that included: The Breckenridge riverwalk is an ecologically sensitive and successful piece of landscape architecture. We looked at this as a precedent for helping develop a framework to guide the landscape architecture team. We feel that something like this could help to improve accessibility to the river while maintaining the quality so as to protect the gold medal fishing status. we also used Larimer Street in Denver is an attractive, lively space and we are looking to this to help inform our design for 4th Street. 4th is a major axis and is the epicenter of our intervention so we felt that we needed to create a safe, comfortable space similar to Larimer to encourage life on the street and help get pedestrians outside and walking about the area.

North Riverwalk The Blue Riverwalk was designed specifically to create a safe, pleasant setting for people, whether they spend a period of time enjoying the scenery or just pass on through. The existing paths on either side of the river would be widened to 12â&#x20AC;&#x2122; making it easier for both bikes and pedestrians to share the space, and allowing free movement in either direction. A couple more simple bridges were incorporated to allow for better passage between across the river. There are a few key areas where there was opportunity for better river access, specifically along the bank near the Black Box Theater, to the side of Festival Bridge, and along the Blue River Park. A design for flagstone steps came from the inspiration of the Singapore River and the Estes Park Riverwalk. The steps would be set into the river bank, leading from the path to the waterâ&#x20AC;&#x2122;s edge, and scatterings of larger rocks and boulders would be dispersed along the steps and down into the water, creating a place for play. This design was made to create easy river interaction while still allowing the water to maintain its ecological integrity.

Festival Plaza Festival Plaza is supposed to be the main node, gathering space, and celebratory area for Silverthorne. One can picture parades, festivals, parties, and gathering that are focused around the Plaza. It is located in the middle of 4th street and Festival bridge and can be considered to be a focal point of that trajectory. It helps anchor and connect the main street of 4th Street to the Activities that will be going on Festival Bridge and the rest of the River Walk.

Festival Bridge Festival Bridge is a pedestrian oriented bridge, that joins existing public gardens with the Festival Plaza, across the Blue river. It should be able to accommodate for farmers markets, active children, as well as people that just want to relax and enjoy the beautiful views by creating a river focused experience for the people of Silverthorne.

South Riverwalk This designed section of the river walk invites pedestrians and bikers to pause and enjoy their beautiful surroundings. The eastern side of the river walk creates views looking over the river and at the mountains right over the town. Pocket parks are created by using a natural form similar to that of a river, and implementing a low level wall for sitting. Areas such as the grass lawn in front of where the summertime ice cream truck park and Boots Park are only improved and left right where they originally were. This design introduces the town of Silverthorne into the beautiful Blue River that is so separated from its core. there was also the implemented priority to set up proper viewsheds for the people in the restaurant and hotels, as well as to create pause moments for people along the paths. A low running wall that spans either side of the river, and twists to mimic the flow of the water, creates a leading feature for the people to either follow or sit on, and enjoy the river from above.

ODI Block 4th Street
Highway 9
Adams Avenue
The architecture team was tasked with designing options for the ODI block. Each option focuses on a different architectural style and material pallet. The ODI block is the main focus of Downtown Silverthorne. We recommend using one design option for any additional city block design. Generally the ODI block acts as a template that should be followed for the rest of the blocks, as development increases.

Option 2: Corner of 3rd Street & Adams Ave. The corner of 3rd and Adams is a building that would start to aid in the creation of a denser town center while still being appropriate for the size of Silverthorne. The building offers a range of residential options from 3000 ft2 down to 500 ft2 to attract a variety of people to the new downtown to maintain human scale the upper stories of the building are stepped away from the street and the faรงade is broken to create a more comfortable feel on the street. Sun and shade is also very important in a mountain climate, so balconies and outdoor spaces are oriented to the south for maximum sunlight, and the upper stories on the northern end of the building are substantially stepped to allow sunlight into the mid-block break.

Option 5: Corner of 4th Street & Highway 9 The building on the corner of 4th St and HWY 9 has a very unique character but one that helps tie the whole design of Silverthorne together. The unique roof line, with pitched roofs, mimics the mountain line behind the building. The materiality follows the mountain modern feel, focusing on mainly steel, wood and stone, to capture the mountain identity. Another focal point of this building is the outdoor circulation. This outdoor circulation helps maximize the amount of windows that can be utilized throughout the design, as well as the amount of natural light that in that area. This circulation, which is anchored by all glass elevators, gives the â&#x20AC;&#x153;courtyardâ&#x20AC;? area of the design a unique feel. The outdoor circulation also faces out towards 4th st, giving a smooth transition onto the 4th St. Landscape design.
