The MAPS program and the 1999 canal completion
MAPS (Metropolitan Area Projects) was the largest publicly-funded downtown improvement program in Oklahoma City's history when it was approved by voters in December 1993. The package included nine major capital projects funded by a temporary 1-cent sales tax that ran from 1994 to 1999. Among the nine projects were a baseball stadium, a new downtown library, the Bricktown Canal, the Civic Center Music Hall renovation, the Cox Convention Center, and the development of Bricktown into a full entertainment district.
The canal itself was designed by Rees Associates Architecture and constructed between 1997 and 1999. The decision to build a canal rather than a more conventional urban improvement project (a park, a plaza, a redeveloped streetscape) was made because the engineers and architects believed a waterway would be more transformative for the surrounding neighborhood. The reasoning proved correct: the canal's completion in 1999 immediately attracted private investment to the surrounding Bricktown warehouses, which began converting to restaurant, bar, and entertainment uses within months.
The canal is roughly one mile long, runs east-west through downtown, and is approximately 25 feet wide with a constant water depth of about 4 feet. The canal water is recirculated through filtration plants on either end — it is not connected to any natural river. The canal level sits about 12 feet below street level, which creates the pedestrian feel of walking along an actual urban waterway rather than a decorative water feature.
