[HYDRO-] TETRIS Studio Pima Water Urbanism

Project Intent: [HYDRO-] tetris, is a modular concept that ameliorates urban flooding and increases green-space through contextual multi-use outdoor basins. The project takes advantage of a variety of empty or underutilized parcels that exist throughout the city, to allow for quick action and problem solving.

[HYDRO-] tetris is one of eight projects In the Pima Water Urbanism Studio class at the University of Arizona, College of Architecture. In this project eight unique proposals rethink the basic assumptions of what a typical rainwater harvesting system looks like and how these decentralized systems can be best integrated into our existing city fabric to achieve expanded infrastructural resilience and long-term water independence.

Where have our rivers gone?

How can we be hydro-logical architects?

FLOOD WATERS Cause and Effect on Urban Spaces

Property Damage

Over the past century, Tucson has become an increasingly urban society. Changes in land use associated with urban development have greatly affected flooding in many ways. The Removal of vegetation and soil in favor of impervious surfaces, has made it impossible for water to enter the aquifer in these locations meaning, the water will be traveling farther, faster,

and will

have picked up more material before it reaches a pervious surface. All in all, this means that

Soil Displacement

there will be more water in a given area during times of rain. The icons to the left showcase the three main problems with urban flooding along with photos of Palo Verde Neighborhood, (an area greatly affected by flooding and our area of focus) after a summer monsoon.

LACK OF GREEN SPACE Area of Focus | Proximity to Green Spaces Another issue that affects many areas around Tucson is a relative lack of green-space for residents. The map to the left showcases how far a resident of Palo Verde Neighborhood will have to travel to reach a public park or recreation area.

APPROACH Traditional v.s. Proposed Solution In the past, problems surrounding flooding have been achieved through large

F A ST

projects.

individual

The traditional example to the

left in red, shows a single storm drain. This drain is effective for small rains, and helps to keeps streets and homes free of flood waters.

However in

large rains, this system becomes overwhelmed with too much water, causing major flooding around these areas, as seen in many neighborhoods around Tucson. Because there is only one in a given area the system is dependent on how large the single drain is, and given the amount of rain during monsoons, the size needed gets very large very quickly for only one month out of the year.

The example in yellow however, utilizes a decentralized approach. Because This

quicker to implement, in addition to being cheaper and dual purposed, there is a higher likelihood of approach is

more of them to exist at any given time. So

more around to take on heavy rains. when one gets overwhelmed there are

FUTURE EXPANSION

Decentralized projects

Expansion of concept to a citywide scale Overall this new way of thinking affords quick action against flooding that can happen gradually over time. While the project may begin in our chosen neighborhood, the idea is that over time these decentralized solutions can exist in many different neighborhoods with a variety of different contexts. The neighborhoods with decentralized action, will then begin to create a much larger city network that will be able to benefit from both decentralized points of quick action, as well as traditional solutions. In the end this concept allows the two modes of problem solving to
