About the Projects
The Waller Creek Tunnel Project is a storm water bypass tunnel beginning with an inlet
structure in Waterloo Park and an outlet structure at Lady Bird Lake near Waller Beach
and the Four Seasons Hotel. Nearly, a mile long, the tunnel will vary between 22 and 26
feet in diameter. The project is expected to reduce the size of the 100-year floodplain of
the lower Waller Creek watershed by an estimated 28 acres and allow denser
development and redevelopment in a very desirable area of downtown Austin. A pump
station at Waterloo Park will maintain constant water flow in the creek during the dry
season, thus improving water quality and fostering a creek side atmosphere suitable for
public venues or natural settings. Creek side inlets located between 4th and 5th streets and
8th and 9th streets will capture and divert additional flood waters south of 12th street.
The tunnel project is
comprised of several construction projects, including utility relocation, the tunnel, the
inlet, outlet, creek side inlets, and site restoration. The Tunnel project will cost approximately $127 million—an initial estimate based on 2006 dollars. Construction will take place from January 2010 until July
2014.

The Waller Creek District Master Plan is a separate, but concurrent, project from
the Waller Creek tunnel project. The master plan will help identify long-term community vision for the development of the entire Waller Creek District and
will outline implementation strategies. Contract negotiations are complete and the ROMA Design Group will lead the process.
The Waller Creek District Master Plan will produce a master plan for the redevelopment of the Waller Creek corridor and the surrounding district. To learn more, visit the Master Plan/Vision page.
