This progress report is a bi- monthly update that FEMA requested as part of the City of Dubuque's Provisionally Accredited Levee (PAL) Agreement that is due in early March 2011. This report is the final PAL Progress Report. 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 City Council officially adopted the July 2002 Operation and Maintenance Manual for the Dubuque levee and floodwall system on May 3, 2010 for submittal to FEMA. Subsequently, the June 2010 USACE report recommended that the City update the Operation and Maintenance Manual and the Emergency Flood Control Plan to ensure that information in both plans was clear, consistent, and coordinated with respect to operation, maintenance and emergency flood control response. City staff completed a simultaneous review of both plans in October 2010. These revised plans were adopted officially by the City Council in November 2010, when they were submitted to FEMA. The USACE report identified two main areas that require further analysis for the Dubuque levee and floodwall system. One area 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, and then selected GEI as the consultant on September 20, 2010. GEI conducted a site visit on October 20, 2010 to begin their analysis. The analysis was completed by December 15, 2010. City staff reviewed the GEI preliminary report on December 29, 2010. The GEI final report was reviewed with Dubuque Levee and Floodwall Certification — PAL Progress Report Page 2 City staff on March 1, 2011. GEI has been contracted to complete an interim risk reduction plan as a final step in completing the structural analysis. The other area is for interior drainage analysis. The City retained CDM to do this analysis as it is an extension of the work the firm completed for the FEMA flood map technical appeal. The analysis was to be completed by December 15, 2010. This work schedule has been extended to April 1, 2011 due to CDM's reconnaissance with the USACE for the 12 sub - basins involved in this analysis. On March 8, 2011, City staff, along with GEI and CDM representatives, met with FEMA staff and their consultants for a Dubuque levee and floodwall scoping meeting. Our levee and floodwall system will be shown on the new flood maps as being provisionally accredited. Based on this meeting with FEMA officials and our levee consultants, we fully expect that our levee will be re- certified. REQUESTED ACTION The requested action is to transmit the Bi- monthly PAL Progress Report #6 to the City Council as an informational item. No Council action is required.

This progress report is the latest bi- monthly update to the One -Year PAL Progress Report submitted in May, 2010 as requested by FEMA. The City of Dubuque 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. The City of Dubuque has retained engineering consultants to complete these analyses by April 1, 2011. On March 8, 2011, City staff, along with our engineering consultants, met with FEMA Region VII staff and consultants for a Dubuque levee and floodwall scoping meeting. The meeting was very helpful, and we appreciate the assistance provided by FEMA for the levee certification process. Please feel contact me if you have any questions or need additional information.
