Dubuque Levee and Floodwall Certification — PAL Progress Report #3

INTRODUCTION
This memorandum transmits the PAL Progress Report #3 to FEMA for certification of the
Dubuque levee and floodwall system along the Mississippi River. This progress report is a
bi- monthly update that FEMA requested as part of the City of Dubuque's Provisionally
Accredited Levee (PAL) Agreement.
DISCUSSION
The City of Dubuque must certify the levee system complies with federal regulations
concerning provision of 100 -year flood protection for the community. This certification must
be submitted before May 17, 2011 and be signed by a professional engineer. We plan to
have a member of the City's Engineering Department provide this certification.
City staff has reviewed the June 2010 Engineering Technical Review Report prepared by
the U.S. Army Corps of Engineers (USACE) on the Dubuque Levee System. Overall, our
levee system appears to meet or exceed most standards according to the report. The
USACE identified two main areas that require further analysis. One is for interior drainage
analysis, which we have retained CDM to do as it is an extension of the work the firm is
doing for the flood map technical appeal. The other is for structural analysis of the levee and
floodwall system to evaluate levee embankment stability. The City Council authorized
issuance of an RFP for this work. We expect to select a consultant by September 20, 2010.
Both analyses are to be completed by December 15, 2010.
REQUESTED ACTION
The requested action is to transmit PAL Progress Report #3 to the City Council as an
informational item. No Council action is required.
