AlleyCEQUIA is a concept proposal submitted for the 2012 California
Architectural Foundation William Turnbull Drylands Design Competition.
Design team members are Steven Chavez, Aaron Clark, Brian Gerich and Ian
Horton, PLA.
This project aims to relocate food production within the urban
watershed, both geographically and hydrologically. It proposes to
retrofit the existing open spaces of alleyways and vacant lots in Los
Angeles with the capacity to store, clean and harvest stormwater.
Water within this system will be managed on a block by block, or
modular, basis. As stormwater falls on the roofs and impervious surfaces
of adjacent lots on a given block, it will be conveyed in the conduit
of the alley and stored in below ground agricultural cisterns. The water
will be reused on vacant lots along the alley – which will be
retrofitted to support urban agriculture and stormwater management. All
overflow from the system will continue into the street at the end of the
block and from there to the existing storm sewers.
Alleys - of which there are approximately 900 linear miles in Los
Angeles - and vacant lots - will also be retrofitted to create a network
of open spaces. Vacant lots will be repurposed to combine urban
agriculture and stormwater management with new civic spaces oriented
towards the connective paths of pedestrian priority alleyways. This new
system of networked open spaces will retrofit Los Angeles towards a
future of healthy active neighborhoods that are built in harmony with
the responsible and sustainable use of water and energy.
