Seasonal water conditions reinforce the adaptation of the site. With time, a new site will reveal itself. Eased edges will start to form in the water channels, while some will dry up and go barren, and others will merge together to create new unpredictable veins. Plant habitats will simultaneously thrive or dwindle based on evolving conditions. DRY DESERT SCRUB

WATER IS LIFE FROM RIDGE TO REEF Indigenous Hawaiians understood water is a source of life and treated it as such. Currently, water is treated as an inconvenience, nuisance, and danger. It is channeled, contained, controlled. Regenerating the Ala Wai Ahupua’a requires treating water as a valued source of life.

By using indigenous Hawaiian knowledge and practices that were implemented to create prosperous, vital, responsive Ahupua’a systems, current degenerative industrial practices can be transformed into those of a contemporary Ahupua’a to be prosperous, vital, and regenerative.
GUIDING PRINCIPLES The Ala Wai Ahupua’a was a prosperity system for all life that, through spirituality and the resulting values and actions of reciprocity and responsibility, perpetuated vitality throughout the system and fostered regeneration of the system as a whole. Spirituality: the awareness and experience of belonging to the larger, interconnected
community of life, of the purpose and meaning of life within this context, and the development of personal and community values and actions out of these Reciprocity: mutual exchange, dependence, action, or influence Responsibility: the state or act of being responsible, answerable, or accountable for something within one’s power, control, or management Vitality: life force and capacity to live and develop with meaning and purpose Prosperity: the condition of thriving, growing and developing vigorously These principles form the core of our approach to ecosystem restoration; flood
mitigation; community education and engagement, cultural connections; community access, mobility, and recreation; and economic health and resilience.
URBANIZATION 1898
Current
1934
CHALLENGES Pollution: The Ala Wai Canal is currently the most polluted body of water in the state. It concentrates storm water from the watershed above. Flooding: A 1% chance storm in the Ala Wai Watershed will flood Waikiki. Fragmentation: Current environmental efforts within the Ala Wai Watershed address disparate environmental problems. DESIGN STRATEGIES We propose 4 key design strategies: planning can begin within 12 months:
1
Waterwalk: Boardwalk + passive flood protection = amenity armament (12 - 48 months)
2
Watercourse: Golf course + wetland = recreational ecology (48 - 72 months)
3
Waterview: Retention + development = infrastructure fund (48 - 72 months)
4
Waterhoods: Storm-watershed + neighborhood = distributed watershed management (12 months - ongoing)
Each of these strategies engages indigenous knowledge to create the foundation of a regenerative, contemporary ahupua’a where private rights have public responsibilities.
1 WATERWALK - Floating walkway connects people to water and nature, provides recreational space, actuates a floating stormwall - Wetland and floating vegetation improve water quality and create habitat - Bioswales with native vegetation capture and clean stormwater and connect users to Hawai’i’s ecocultural roots - Creates economic and so cial value for local businesses and community - Platform for community engagement in ecocultural and scientific education, stewardship, monitoring, and recreation

weave.
a strategy for urbanism and shared space in phoenix’s warehouse district.
downtown phoenix is organized among three axes, existing as three major streets, 7 Ave, Central Ave, and 7th St. although less apparent, certain dividing lines exist on top of these organizing elements; the downtown core, greater downtown, the warehouse district, and the southern residential areas. People also move along these set of axes. Sports fans create striations from the residental area parking to the arenas, music and art seekers move from northern roosevelt row eventually south, draping circulation over downtown. downtown employees generally draw a line from the highway or aertial street to the government mall district and surrouding area. Together these motives create an urban weave that amounts to downtown pheonix. the warehouse district must respond to this in order to successfully serve its nightlife and residential neighbors.

The Ribbon Downtown Phoenix is a lively and diverse area that never sleeps. There are always events from concerts to baseball games. Downtown Phoenix is where all the adjacent cities that make-up the Valley join, creating a focal point. Whether traveling from the North, East, or West side of the Valley, there is a pleasant experience transitioning into the jungle that is Downtown. The South side however has a buffer, the warehouse district, preventing an inviting transition into the area. The goal is to revitalize this once prominent area and invite the adjacent neighborhoods.

The Master Plan for the new vision of the Warehouse District shows a collection of spaces utilized for outdoor activity. It is designed to get people to react within the environment and question their role as a Phoenician. There are various parks throughout the site including a larger ribbon of green space which replaced existing vehicle parking. Alongside this greenbelt are a skylight looking down at Central Avenue, a graffiti park for local artists, and a playground for all ages. Tying these spatial elements is a red interactive ribbon which ties the knot on the buffer between South Phoenix and Downtown, connecting all adjacent municipalities and cities into the center of the Valley.

SIMPLE OBSERVATION EXPERIENCE WHEN THE NIGHT COMES TO LIFE WESTERN SCREECH OWLS AT MOEUR PARK
VISION The Western Screech Owl Observatory at Moeur Park is a project created for the use of both humans and Western Screech Owls during the hours of both the day and the night. By revitalizing an area encompassing riparian, bosque, and wash ecologies, and by utilizing a native plant pallet, the Observatory will be a sanctuary for Western Screech Owls in an otherwise dominantly urban environment. The project focuses on contrasting night and day experiences to introduce visitors to the intriguing nocturnal life of the Western Screech Owl and the beautiful desert world that comes to life at night.
GOALS 1. Enhance the natural riparian, bosque, and wash ecologies within the habitat. 2. Emphasize the contrast between natural and urban environments. 3. Create a space that appeals to visitors of all ages. 4. Inspire interest about the Western Screech Owl species. 5. Expand the visitors’ ideas of perception of the site in the day versus the night.
WESTERN SCREECH OWL
CONTEXT Moeur Park is a southern extention of Papago Park, located to the east of Mill Avenue and north of Red Mountain Freeway in Tempe, Arizona.
Small compact owl averaging nine inches tall with bright yellow eyes and grey, brown, or rufus coloring. Sound is extremely important to their existance. Their unique ping-pong-like call is used for communication and mating purposes, and hunting is focused on hearing rather than spotting prey.
Habitat chosen for location by five main trails, and bosque, riparian, and wash ecologies.
Roost in cavities in deciduous trees, specifically the Cottonwood, or in saguaros in a desert environment. They exist in riparian, bosque, and wash ecologies.
THE OBSERVATORY Trail system includes four external resting areas with benches and shade.
Night garden contains native plants that flower only at night.
Slightly winding pathways mimic the mysterious and curious nature of the night. Trails were also influenced by the fascinating vein structure of the owl, which allow them to turn their heads so far without injury.

Smallest arch stands at 12’-0” tall and 1’-6” thick. Height gradually increases down the slope until the tenth arch at 27’-0” tall. Structure mimics the surrounding rock formations in Moeur Park or sound waves, which Western Screech Owls rely on for hunting, mating, and communication. The heavy material has a secure feeling, but separate arches allow for openness and a view of the stars at night.
Structure contains solar powered information boards and night vision telescopes to survey habitat at night.
