Total study costs estimated at $38.4 milliono 50/50 cost share Federal and City
Citys 2009 contract award to HNTB includes an estimated
$23 million directly applicable to this new Feasibility Study
Citys cost share requirements already met
However, in order to maintain schedule, WRDA language
allows City to provide funds to keep study progressing WRDA language provides opportunity for credit of Citys
additional funding toward future phases of projectdevelopment
Remaining study costs estimated at $15.4 million

Presidents Budget request comes out inFebruary for the next fiscal year
Congress is scheduled to approve budgetsby October of the current fiscal year
If appropriations bill is not approved at that
time, temporary funding is providedthrough a continuing resolution until finalbill is approved
Continuing resolution typically limits theamount of funding available

Needed for FY 10 (ending 9/30/10) $4.70 M Needed for FY 11 thru 3/2011* $2.05 M USACE funding FY 10 ($1.30 M)
USACE funding FY 11** ($0.70 M) TOTAL FUNDING NEEDS $4.75 MFOR USACE thru 3/2011
To keep the study moving at full speed, the Cityneeds to advance $4.75 M to USACE
* In the event that the appropriations bill is not passed by the start of October 2010,the City proposes to provide funds to maintain schedule
** Included in Presidents Budget; however, there is an opportunity for additionalfunding through Congressional appropriations bills that could increase this amount

WRDA 2007 language allows the City to receive credittoward future design and construction phases of the
project for any City contributions over 50% cost shareduring the Feasibility Study
When the Dallas Floodway project begins design
and/or construction phases, agreements between Cityand USACE will incorporate this credit, thereby
reducing the Citys future funding requirements
How does the City get credited for
advance contributions?

Council approval on March 10, 2010 of FCSA andto provide $4.75 million to USACE to ensurecontinued USACE progress through March 2011
If federal funding does not meet project needs forFY 11, City may be required to provide additionalfunds at that time
