Gateway Speaker Bios Christopher Brown, FASLA, LEED AP SmithGroupJJR Chris has focused much of his 30 year career towards planning and landscape projects that seamlessly incorporate public space into the environmentally sensitive landscape of the Sonoran Desert. His internationally recognized work includes the Rio Salado Audubon Center (LEED Platinum), Cavalliere Park (SITES Pilot) and a series of award winning projects within the McDowell Sonoran Preserve that allow the user to be completely immersed into the desert environment while protecting the sensitive nature of the desert habitat. Philip Weddle, AIA, LEED AP Weddle Gilmore Philip s work focuses on designs that are responsive to unique cultural, climate and site-specific influences and includes an award winning series of projects that explore the relationship between the rapid urban growth of the Phoenix Metro area and the Sonoran Desert it inhabits. Weddle Gilmore has completed work throughout the southwest as well as Europe and Asia and is internationally recognized for environmental excellence in design. The firm was awarded the AIA Sustainable Firm of the Year in 2008 and the AIA Firm of the Year in Scott Hamilton, Senior Preserve Planner As Senior Preserve Planner, Scott is responsible for the planning and implementation of the McDowell Sonoran Preserve an area of permanently protected Sonoran Desert which will total 34,000 acres upon completion. Since joining the in 1998, Scott has played a key role in the planning and construction of an interconnected system of trails and trailheads which provide public access to the Preserve, including direct involvement with the Preserve s land acquisition process.

4 Pinnacle Peak Park Trailhead The Pinnacle Peak Trailhead is a City of Scottsdale park and trailhead facility. The structures, landscape, trails and interpretive elements are sited into a very rich and unique landscape sensitive to the desert environment. Interpretive components focus on the Sonoran Desert ecology and the historical connections of the various cultures that have inhabited the valley. The site design focuses on minimizing the impact of the trailhead development on the existing vegetation. This was accomplished by terracing the parking to reduce grading limits, revegetation of previously disturbed habitat and the use of decomposed granite pavement. The trailhead structures blend with the native landscape and geology through the building forms and materials. The thick walls of the trailhead are constructed of desert stone masonry utilizing native granite boulders stockpiled from previous development. The roof, constructed of rusted cor-ten steel, collects rain which is stored in a cistern before being distributed to site landscaping. An overhead cable trellis system designed around an existing mature saguaro serves as a centerpiece to the trailhead.

5 Lost Dog Wash Trailhead The Lost Dog Wash Trailhead facility is the third in a series of projects the team has completed for the City of Scottsdale s McDowell Sonoran Preserve. This major access facility is designed to provide a southern gateway into the 34,000 acre Preserve. The project has been recognized internationally and now serves as the model for all future Preserve Access Areas and desert sensitive design in general. Lost Dog Wash was designed to integrate into the existing environment, to the highest degree possible, including the design of a rain and graywater collection system to eliminate the use of potable water, LED lighting utilizing solar photo voltaic panels, composting toilet system and stabilized granite parking and drive lanes to eliminate the use of all asphaltic paving on the project. The project involved intensive field reconnaissance to site the improvements, preserve and/or salvage all native material from disturbed areas, preserve existing drainage washes and to limit the areas of grading disturbance. The plant palette includes only site specific species, based on comprehensive pre-construction site inventory.

6 The Gateway to the McDowell Sonoran Preserve The Gateway is the fourth in a series of projects the team has designed for the s McDowell Sonoran Preserve. In conjunction with the Desert Discovery Center planned for the same site, The Gateway Access will serve as one of the primary access points to the 34,000 acre Preserve. The facility provides outdoor classroom spaces, interpretive displays, offices and meeting rooms for Preserve rangers, as well as parking for autos and equestrian trailers. The Gateway Access Area is designed to integrate into the existing environment, utilizing sustainable construc- tion techniques such as rainwater harvesting, low water use irrigation, LED lighting and stabilized decomposed granite paving. Intensive field reconnaissance was conducted during the master and site planning process to properly site the improvements to minimize disturbance and to preserve existing drainage washes. All native trees, shrubs and cacti were salvaged from all disturbed areas and reincorporated into the landscape through a site specific revegetation process. The plant palette and planting design includes only site specific species and reflects native site specific densities.

7 George Doc Cavalliere Park Preserving open space, respecting existing neighborhoods and creating a demonstration project for sustainability, were the primary guiding principles in the design of George Doc Cavalliere Park. Cavalliere Park (formally Troon North Park) is the result of over 20 years of planning and is a product of not only extensive community input but also the significant challenges of integrating a community park into a regional stormwater retention facility, set into the rugged desert terrain of north Scottsdale. The resulting project has established a new standard for the design and implementation of a truly sustainable community park for the. It is fitting that George Doc Cavalliere Park has been named after one of Scottsdale s founding fathers. Sitting adjacent to Doc s beloved Greasewood Flat, the new park establishes a vision for uniting Scottsdale s past and future. Cavalliere Park was selected to be a part of the pilot program for the Sustainable Sites Initiative (SITES) and is on track to be the first project in the state of Arizona to receive certification under the SITES Benchmarks & Guidelines.
