Re: Accept Barr Engineering Proposal for FEMA Required Provisionally
Accredited Levee Certification
Council is requested to accept the enclosed proposal from Barr Engineering to
perform the necessary studies needed to certify the Vermillion River levee as
required by FEMA in order to count the Westwood neighborhood as being
protected from the loo year flood event.
BACKGROUND
As part updating the Flood Insurance Rate Maps, FEMA is requiring
communities to certify that levees meet current design and maintenance criteria,
a process that involves surveys, soil borings, stability analysis, interior drainage
review, settlement analysis, and review of operations and maintenance plans.
The City has one levee that falls under this review; a l,ooo ft. long levee along the
Vermillion River located adjacent to Dakota County Shop on CSAH #46/47.
I have enclosed a drawing of the new Flood Insurance Rate Map (FIRM)
illustrating the Westwood neighborhood area that is protected by this levee. By
certifying this levee, the FIRM will acknowledge that the Westwood
neighborhood area is protected against flooding, which is an important
consideration for mortgage lenders and insurers.
The levee certification is due in January of 2010. The 2009 budget included
$55~00o to cover the levee certification studies. The Barr proposal estimates the
certification cost at approximately $51,000.

Subject: City of Hastings Flood Control Project Levee Certification: Scope of Work
Date: March 2008
Project Understanding
For FEMA to continue to accredit the City of Hastings Flood Protection Project with providing
protection from the base flood, the levee and associated structures must meet the requirements of the Code
of Federal Regulations, Title 44, Section 65.10 (44CFR 65.10), entitled "Mapping of Areas Protected
by Levee Systems." Specifically, the design and construction data provided must be certified by a
registered professional engineer or by a Federal agency with responsibility for levee design.
The levee was built in the mid-sixties and has withstood several design floods since its construction.
In order to formally certify the levee, the FEMA must review and certify the design analyses,
construction, operation, and maintenance for the levee. For this scope Barr is assuming that certified as-
builtdrawings are not available. Further we assume that only minimal design detail information is
available.
Based on these assumptions, a full review of the site characteristics, design, and construction will be
needed.
Project Approach
Toward accomplishing the needed FEMA certification, Barr will compile all relevant data, drawings,
and analyses. Barr will then perform additional testing, drawing revisions, and engineering analyses as
needed to meet Federal regulations. Barr will also develop the required operation and maintenance
plans and manuals for the structures. Barr will then submit the documentation required with a cover
letter and/or other required forms to the FEMA for their review and approval In consultation the
City, with Barr will respond to comments and/or make revisions to the documentation as required by
FEMA.
Barr assumes that the existing infrastructure has been designed and installed to meet the Federal
regulations and that additional design for modifications is outside the scope of this proposal.
Barr estimates the project costs to total $51,110. For planning purposes you might want to budget
$55,000.

Task 1: Gather Data & Survey Costs: $19,800
This task includes compiling all readily available data regarding the City of Hastings Flood Protection
Project including drawings, design calculations, and/or studies. Based on the information obtained Barr
will prepare a list of additional information or study that is required to meet the Federal regulations. Barr
will refer to appropriate Federal regulations and consult directly with FEMA staff to finalize this list.
This task will also include a detailed survey of the site in order to produce a certified as-built drawing
to demonstrate proper construction.
This task will include one meeting with city staff to kick off the project.
Task 1 Deliverables:
1. One (1) project kick-off meeting.
2. List of task and items to be produced.
3. Detailed certified survey of site.
4. CAD drawings of site needed for documentation and analyses.
5. Soil borings and testing, if needed.
6. Bi-weekly telephone and/or e-mail updates/discussions with city staff.
Task 2: Perform Engineering Analyses Costs: $15,200
Under this task Barr will perform all engineering analyses required for the FEMA certification,
including but not limited to, freeboard review, review of closures (flap gates), embankment protection
analyses, embankment and foundation stability analyses, settlement analyses, and interior drainage
review. All engineering analyses will be carefully documented and certified by a Registered
Professional Engineer.
Task 2 Deliverables:
1. Engineering analyses as required for certification by Federal Regulations 44CFR 65.10.
2. Certification by a Registered Professional Engineer.
3. Bi-weekly telephone and/or e-mail discussions with city staff.
