The Trinity River corridor projects address regionalconcerns but flood risk reduction is the cornerstone.

4 inter-related components of the projects are:

I. Flood Risk ReductionII. Ecosystem Restoration

III.TransportationIV.Recreation

Flood Risk Reduction History

1949Fort Worth flood kills 11, flood control reservoir

construction advances (Lewisville, Grapevine, Benbrook) 1958Corps completes major Dallas Floodway upgrade

1989-1991Worst floods since 1908. 1998Dallas voters authorize record bond package $246

million for Trinity flood control, transportation and recreation.

1908Dallas flood kills 5, leaves 4,000 homeless, citywithout power for days, massive property damage

1928First levee system built in Dallas

14/95

Flood Risk ReductionDallas Floodway Project

2007 Water Resources Development Act (WRDA) Section 5141was authorized to raise the levees up to 2 feet, provide recreation(Balanced Vision Plan) and improve pump stations

2009Corps tells City it has rated Dallas Floodway unacceptable;

FEMA withdraws accreditation of levees; city begins maintenanceand construction work to re-certify levees

2010Feasibility Study and Environmental Impact Statementprocess launched to explore what actions are needed to restorecapacity of Dallas Floodway to meet a major storm event.

2011 Corps introduces Risk Assessment process, a cost-effectivemethod for assessing aging dams, to the Dallas Floodway Project. First of this type of study for levees in the Country

Determines Dallas Floodway Project Levees are more resilient and providearound 1,500-year protection

13


15/95

Flood Risk ReductionThe Risk Assessment Process

14

Method for quantifying the risk (likelihood) of various ways a leveecan fail, and the consequences of each failure type

Identifies most cost-effective ways to reduce risk

Overtopping with breach

Successful result: Determined levees moreresilient than previously thought

Narrowed the list of 13potential failure modes to two:

Overtopping with breach ofEast or West Levee

Overtopping of the EastLevee floodwall


16/95

Flood Risk ReductionRecommended Flood Risk Management Plan

15

Raise low spots in the levees up to 3 feet to increase flood conveyanceto 277,000 cubic feet per second. This is enough to convey floodwaters ofa major storm that has a 1/2,500 chance of happening any given year

Cost of these two changes: $6.2 million

Old abandonedAT&SF TrestlesProposed for Removal

The Trestles are on 14-foot-centers and collect debris during flooding andstack up floodwaters into the floodway. The embankment acts as a weirand impedes flow down the floodway system
