The Fiscal Year 2008 Prioritization Procedure recommended this project as a component of the Downtown Phoenix Drainage Improvements Project that was concurrently being studied under the Metro Area Drainage Master Plan (ADMP). The Metro ADMP subsequently recommended the Downtown Phoenix Drainage Improvements Project as a subset of its recommended downtown alternative.

This system includes three project-areas: north and south of Fillmore Street from 2nd Avenue to 9th Avenue; north and south of Jefferson Street (Monroe Street to Jackson Street) from 2nd Avenue to 19th Avenue; and along 1st Avenue from Van Buren Street to Hadley Street. Specific alignments will be determined during the final design process. When combined with the complete downtown system recommended by the ADMP, this project will deliver a 10-year level of protection for the downtown area. Phoenix is acting as lead agency for project design and construction, and the District intends to contribute 50 percent of the project cost.


The Fillmore Street storm drain project was completed in the summer of 2011. Phase 1 of the Jefferson Street storm drains was completed in 2012. Phase 2 of the Jefferson St. storm drains was completed in July 2014. Design and construction of the 1st Avenue-Area-Component will likely require the approval of additional funding in a future City bond election.
