For thousands of years, people have been shaped by their encounters with the Grand Canyon: now it is our turn. Our work at the Canyon View Information Plaza and Mather Point Overlook was inspired by the majestic views, geological formations, and fragile ecology of the canyon.
INSPIRATION THE PLACE 05
INSPIRATION
We found inspiration in the formation of side canyons and the springs born there. The rich cultural history of the area moves us to protect and embrace the fragile ecological communities where layered desert rock meets lush green growth.
THE PLACE 07
THE PROJECT Create a setting that gracefully hosts millions of annual visitors and allows them to experience a sacred connection to the Grand Canyon. Provide opportunities to experience and understand the environmental interrelationships, resources and values of the Grand Canyon without impairing the site and surrounding ecology.
THE CHALLENGE
CHALLENGES
Attendance at the park has outgrown existing infrastructure and has begun to have a detrimental impact on the delicate ecology surrounding high traffic areas.
THE PROJECT 11
Built in the 1930’s, the existing 250 car parking lot along the rim quickly became insufficient and also separated visitors from the landscape. Since that time, the number of parked vehicles along the rim grew to over 600 cars during the peak visitor season. Visitors parked along the road and trudged through the fragile limestone, juniper and pinyon pine ecosystem to reach the canyon rim.

THE PROJECT 13
Our team relocated parking away from the rim, establishing it near the Grand Canyon Visitor Center, Transit Pavilion, and the newly reactivated transit hub. Visitors can now ride the shuttle, walk, or cycle to and from the Grand Canyon Village, along the South Rim to multiple trailheads and the Hermit’ s Rest.

STORMWATER MANAGEMENT The additional vehicular and tour bus parking impacts were mitigated through a conscious effort to mimic natural hydrologic processes, reduce the flow of pollutants, and control erosion.
The installation of interpretive signage educates visitors about ways in which sustainable elements were incorporated into the landscape, and how natural processes provide for a healthier environment through stormwater control and improved water quality.
SOLUTIONS
The drainage system treats stormwater in a series of sand filter infiltration systems designed to be both functional and attractive. The natural filtering ability of the soil removes pollutants in stormwater runoff. Check structures were used to flatten the overall slope of the drainage swales in order to dissipate the energy of the flowing water, reducing the potential for erosion and enhancing the riparian vegetation and water quality.

IN T E R P R E T I V E E DUCATI ON The overarching concept of this landscape is a message of climate change. Opportunities for visitors of all ages to experience the diverse plants and animals associated with the wet and dry habitats of the canyon include dripping rocks for hummingbirds, mud puddles for butterflies, and fossil discovery.

VISITOR CENTER A new visitor plaza displays interpretive kiosks outside the visitor center, accessible 24 hours a day, to provide orientation information. A better understanding and appreciation of the park forges emotional and intellectual connections with the Grand Canyon and the rest of the National Park System.
VISITOR CENTER THE PROJECT 29
The plaza’s numerous sandstone slabs are carved with images of the plants and wildlife found within the canyon, quotations, animal tracks, and a life size mountain lion, lounging on a secluded rock. The plaza was designed to serve as an interactive discovery area which can be explored by individuals at their own pace or on a guided tour.
VISITOR CENTER THE PROJECT 31
tHE landmark / cultural history Awareness of Native people and their cultural history with the Grand Canyon is realized through a sculptural space between the Rim and the Visitor Center. Stories, symbols, and tribal connections with the canyon are engraved on locally quarried Kaibab limestone slabs. The intent of the landmark is to help clear away the distractions of daily life and set the stage for a sacred encounter with the Canyon.
MODEL OF LANDMARK FEATURE
CONSTRUCTION THE LANDMARK 35
WAYFINDING THE LANDMARK 37
The park and design team collaborated with local Tribes to build a sculptural space where large Kaibab limestone slabs are engraved with stories and symbols provided by the Tribes. The stories reflect and reveal the Native Tribes’ profound connection with the Canyon and its resources.
THE LANDMARK 39
ENGRAVED STORIES & SYYMBOLS
EDUCATION
Just the act of initiating meetings with the Tribes was a cleansing process that gave them the opportunity to tell their story of the land. The design doesn’t try to tell the whole story, but underlines strong elements that remind people of the Tribes’ perspective and history.
THE LANDMARK 41
THE amphitheater & rim trail Culminate the journey from the Visitor Center to M ather Point and the R im Trail with breath- catching views that balance the experience with appropriate measures of safet y. Accommodate the widest range of ages and abilities with accessible exploration of the rim. Facilitate varied forms of events from personal contemplation and star- gazing, to stor ytelling, presentation, and per formance.

The planting concept extends like fingers of Great Basin desert scrub from the side canyons into the existing pinyon-juniper woodlands. The planting ecology concept proposed reestablishing the limestone habitat of the Great Basin Desert Scrub woven amongst the pinyon-juniper habitat.

The changes made to the built environment are intended to meet the exponential visitation growth that the park has experienced in recent decades. Now it is a much more peaceful experience that allows for the adrenaline rush of standing on the edge without putting anyone in real danger.

The improvements were designed to provide all people with a smoother, more generous approach to the extreme viewpoint of the rim. Previously, those who couldn’t negotiate stairs and a longer walk simply missed out. Now a gentle ramp reaches the very tip where the view is the most spectacular. Everyone gets to experience it.
