DATE: April 27, 2010
In March of 2010, the City Council authorized the release of a Request for Proposal
(RFP) for a consultant to perform the necessary engineering analysis, prepare the
necessary documentation, and submit an application for a Letter of Map Revision
(LOMR) to FEMA to revise flood hazard zones identified in the Digital Federal Insurance
Rate Map (DFIRM) proposed by FEMA for the City of Dubuque.
Four proposals were received in response to the RFP.
City Engineer Gus Psihoyos, Planning Services Manager Laura Carstens, and the RFP
Review Committee recommend the City Council approve the hiring of Camp Dresser &
McKee based on their significant knowledge of FEMA's LOMR application process, their
track record of preparing LOMR applications to FEMA's satisfaction, and their
knowledge of the City's stormwater management system. Camp Dresser & McKee's
cost proposal was $48,918, which is under the City's estimated cost of $50,000.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

FEMA Flood Plain Mapping — Consultant Selection for the Preparation,
Submittal, and Implementation of a Letter of Map Revision (LOMR)
INTRODUCTION
The purpose of this memo is to request authorization to hire a consultant to perform the
necessary engineering analysis, prepare the necessary documentation, and submit an
application for a Letter of Map Revision (LOMR) to FEMA to revise flood hazard zones
identified in the Digital Federal Insurance Rate Map (DFIRM) proposed by FEMA for the
City of Dubuque.
BACKGROUND
On July 15, 2009, the City of Dubuque received the preliminary map and the Flood
Insurance Study Report as part of FEMA's Flood Map Modernization Program. The
program is designed to update on a nationwide basis the flood insurance rate maps of
member communities and counties in the National Flood Insurance Program (NFIP).
The City of Dubuque supports FEMA's nationwide effort to have accurate flood plain maps.
However, the Planning Services Department and the Engineering Department are
concerned with the inaccuracy of the methods utilized by FEMA to produce the DFIRM
proposed for Dubuque.
FEMA utilized cost - effective "approximate" methods to establish the new flood zones
proposed in the North End Neighborhood and the Washington neighborhood, in the
Keyway /Keymont/Keymeer area, along Kaufmann Avenue, along West 32nd Street, and in
the Kerper Boulevard industrial area. The citizens of Dubuque have made significant
investments in these areas. Designation of these areas as Zone A flood hazard areas will
place an additional financial burden on homeowners and businesses in these areas and
likely lead to disinvestment and blighted conditions.
FEMA has proposed a map that would significantly expand the number of properties in the
city designated as being in a regulated flood plain from 70 structures to over 1,700
structures!
In March of 2010, the City Council authorized the release of an RFP for the engineering
analysis, preparation of documentation, and submittal of an application to FEMA for a
LOMR that would revise the flood hazard zones identified in preliminary DFIRM based on
the more detailed analysis.

DISCUSSION
Since the North Fork Catfish Creek and the Bee Branch are separate flooding sources,
requiring separate LOMR applications, the RFP allowed responders the option of
proposing to perform the necessary work associated with just the North Fork Catfish Creek
LOMR, just the Bee Branch LOMR or both LOMRs.
The City received four proposals. Camp Dresser & McKee Inc. (Milwaukee, WI) with
WHKS (East Dubuque, IL) submitted a proposal to study and prepare a LOMR application
for both the Bee Branch and North Fork Catfish Creek watersheds. IIW Engineers &
Surveyors, PC (Dubuque, IA) submitted a proposal to study and prepare a LOMR for just
the North Fork Catfish Creek watershed. MSA Professional Services (Dubuque, IA)
submitted a proposal to study and prepare a LOMR application for both the Bee Branch
and North Fork Catfish Creek watersheds. Strand & Associates, Inc. (Madison, WI)
submitted a proposal to study and prepare a LOMR for just the Bee Branch watershed. A
summary is as follows:
Firm NF Catfish Creek Bee Branch
Camp Dresser & McKee yes yes
IIW Engineers yes no
MSA Professional Services yes yes
Strand & Associates no yes
While the proposals established that each firm is familiar with the LOMR process, Camp
Dresser & McKee (CDM) stood out for a few reasons.
1. CDM's proposed project team has reviewed and /or prepared more than 200 LOMR
applications in the past five years. In the past five years, proposed task leader
Jaspreet Randhawa has reviewed 180 applications on behalf of FEMA Regions I
and X. Having served in the role of a reviewer for FEMA, CDM has firsthand
knowledge of FEMA's expectations with regard to LOMR applications. The
proposed Quality Control team member Delton Schwalls has prepared 15 LOMR
applications in the past five years, one of which was approved without any FEMA
technical comments and only one regulatory comment.
2. CDM has firsthand knowledge of FEMA's map modernization program having
completed mapping projects for clients in FEMA Region VII. In the Midwest, CDM
has performed floodplain mapping in 44 counties in the last five years.
3. Based on the knowledge they have acquired through the preparation of nearly 100
LOMRs in recent years, CDM has established in -house procedures and protocols
that align specifically with FEMA's standard quality requirements.
4. Having completed the Bee Branch Creek Alignment Study, CDM has a firsthand
knowledge of the existing electronic hydrologic and hydraulic models having played
a role in their development.

Based on their significant knowledge of FEMA's LOMR application process, their track
record of preparing LOMR applications to FEMA's satisfaction, and their knowledge of the
City's stormwater management system, the proposal review committee consisting of
Planning Services Manager Laura Carstens, City Engineer Gus Psihoyos, Finance Director
Ken TeKippe, Associate Planner Kyle Kritz, and Civil Engineer II Deron Muehring
recommends that the City hire CDM to prepare LOMR applications for the North Fork
Catfish and Bee Branch watersheds.
The proposed fees are as follows:
'Fee for just the North Fork Catfish Creek LOMR
2 Fee for just the Bee Branch LOMR
RECOMMENDATION
We recommend hiring the consultant team of CDM and WHKS to perform the necessary
engineering analysis, prepare the necessary documentation, and submit an application to
FEMA for a LOMR for both the North Fork Catfish Creek and Bee Branch watersheds.
BUDGET IMPACT
CDM's cost proposal is $48,918.00, which is under the City's estimated cost of $50,000.
The work will be funded with Stormwater Management Funds.
ACTION TO BE TAKEN
We respectfully request authorization to negotiate and enter into a contract with CDM for
the engineering analysis, preparation of documentation, and submittal of an application to
FEMA for a LOMR that would revise the flood hazard zones identified in the preliminary
DFIRM based on the more detailed analysis.

Subject: Proposal - Bee Branch Watershed and North Fork Catfish Watershed LOMR
Applications
Dear Mr. Muehring:
Since 1971 when it joined the National Flood Insurance Program (NFIP), the City of Dubuque
has been proactive in its efforts to provide updated information on its floodplains and
watersheds to the Federal Emergency Management Agency (FEMA). However, because of
FEMA revisions to maps in August 2009 that did not include the latest data and available
detailed information, the City must update hydrology and hydraulics (H&H) analyses to
establish floodplain boundaries and base flood elevations (BFEs) and then submit the
information with a Letter of Map Revision (LOMR) application.
The key to success for this project is understanding the FEMA LOMR application
requirements so that the application is comprehensive and complete, which will facilitate a
swift review and subsequent approval.
The CDM team brings the required expertise to help you achieve a successful LOMR:
• LOMR review and preparation. Combined, our proposed project team has reviewed
and/or prepared more than 200 applications in the last five years. One of our largest
ongoing LOMR review efforts is for FEMA Regions I and X, a project that aims to have 80
percent of the U.S. stream miles mapped to end -use standards in five years. To date, we
have processed 14 applications. On the individual level, several of our proposed project
team members shine. LOMR task leader Jaspreet Randhawa has reviewed 180 applications
and prepared five in the last five years. QA /QC team member Delton Schwalls has
prepared 15 applications in the last five years, one of which - a conditional LOMR for the
Mr. Deron Muehring
April 15, 2010

Hartsfield- Jackson Atlanta International Airport - was obtained without any FEMA
technical comments and only one regulatory comment.
• Knowledge of FEMA Map Modernization Programs. CDM has completed mapping
projects for clients in FEMA Regions I, IV, V, VI and VII. To date, we have completed more
than 7,000 map panels in 630 communities and performed more than 15,000 miles of
floodplain mapping from digital conversion. In the Midwest alone in the last five years, we
have performed this work in 44 counties and in four of the six Region V states.
• Established in -house procedures and protocols that align with FEMA processes. In 2006,
CDM developed an internal quality assurance /quality control (QA /QC) program that
aligns specifically with FEMA's standard quality requirements. Team member Onur Celik,
C.F.M. is both a coordinator for this program and a co- author of internal FEMA program
procedures, which encourage successful procedure development efforts for H &H analyses,
Digital Flood Insurance Rate Maps (DFIRM) production and project initiation.
• First -hand understanding of the unique H &H hydraulic attributes of the Bee Branch. As
the City well knows, the Bee Branch watershed is hydraulically complex with regard to
overland flow paths and ponding areas during wet - weather events. As part of our team's
work on the Bee Branch alignment study, we developed a SWMM model that addressed
several of these issues. This previous work provides us with a head start in the analyses
and floodplain delineation for the Bee Branch watershed.
Required Statements
• Proposal validity: As requested, our proposal remains valid for 90 days.
• Understanding of final contract terms: The final contract terms as outlined in the RFP are
understood and acceptable.
• Certificate of insurance: After reviewing the City's insurance requirements, we propose to
review /verify the endorsements with our insurance agent. Specifically: for Additional
Insureds, CDM uses form ISO CG 201010 -01, not the requested 07 -04 version; for
Governmental Immunity, we use form ISO CG 241411 -85. We do not anticipate that this is
a problem, but would need to confirm this when we request an insurance certificate for the
City.

The overall goal for this project is to gather all
of the known information on both flooding
sources and new flood control structures, and
develop representative base flood elevations
(BFE) and floodplain delineations and
incorporate them into a Letter of Map
Revision (LOMR) application package. A
complete application package - and a swift
subsequent FEMA review - is contingent
upon our team's understanding of FEMA
requirements, which is highlighted in this
section.

H &H analyses of the
1,150 -acre floodplain
enabled CDM to make
recommendations to
the City that would
reduce flooding in the
watershed.
On July 17, 2001, the
City of Mason, Ohio
experienced a 1- percent
annual chance (100 -
year) storm event that
resulted in the flooding
of many businesses and
residences located along
Davis Run. Following
this event, the City
identified the Davis Run
floodplain as one of
their most critical flood
hazard areas and retained CDM to perform an
H &H analysis of the 1,150 -acre floodplain in
order to update and revise the revised FEMA
floodplain, as well as make recommendations
to reduce flooding in the watershed. Tasks
included evaluating the effects of recent high -
intensity storm events, developing the 10 -, 25 -,
50- ,100 -, and 500 -year flood profiles within
Davis Run and preparing /submitting the
LOMR application.

Section 2: Scope of Services
Project Approach
Based on the RFP and our understanding of
City of Dubuque's (City) watersheds, CDM
has developed a project approach for each of
the tasks in the scope of services, as detailed
below. Each task description concludes with a
list of deliverable(s). CDM staff will work with
the Engineering Department to obtain data
that is necessary to efficiently develop /update
the H &H models consistent with FEMA
guidelines for ZONE A portions of North Fork
Catfish Creek (NFCC) and Bee Branch (BB)
watersheds, develop base flood elevations and
1- percent annual chance floodplain
boundaries, and prepare LOMR applications
consistent with the guidelines outlined in
FEMA's MT -2 Forms (LOMR application
forms). Our approach is based on preparing
LOMRs for both the NFCC and CC flooding
sources.
We understand the City's current situation. It
has received the new preliminary FEMA flood
hazard mapping which includes significant
reaches of Zone A which have placed large
numbers of properties within the floodplain
based on approximate methods and old
information. The purpose of this project is to
develop revised floodplain mapping for these
reaches that would be more representative of
the true flood risk and then submit that
information to FEMA in a LOMR. Our
extensive experience with FEMA's Map
Modernization program and LOMR studies
will enable us fully understand the City's
needs and deliver LOMR applications to
FEMA within City's anticipated timeline.
Task 1: Data Collection, Review of
Existing Models and Develop Field
Survey Plan
CDM will meet with the City's engineering
staff at the beginning of the project to collect
the available data and also to interpret the
source and background of the data. It will be
important to define and receive the required
project data and documentation in a timely
CDM
manner in order to meet the City's submittal
schedule.
CDM will review the existing H &H models
for ZONE A portions of both the NFCC and
BB watersheds and will determine if the
models are compliant with the FEMA
guidelines (FEMA Guidelines and
Specifications, Appendix C, Riverine Analysis
and Mapping). Based on the review, CDM will
develop a field survey plan, which will be
developed consistent with the FEMA
guidelines. The survey will be conducted by
team member WHKS & Co. with guidance
from CDM. The survey will include 5 natural
cross sections, 4 hydraulic structures
(including transition cross sections), and
elevation verification points on adjacent
detention storage facilities. Our survey level of
effort assumes that the benchmarks used in
the field survey meet NGS accuracy standards
as per FEMA guidelines based on previous
work done by WHKS in the area.
Task Deliverables:
• Draft report section for the LOMR H &H
report summarizing the findings from
review of the existing H &H models and
available data
• Field survey as specified
Task 2: Develop Hydrology and
Hydraulic Models
Hydrology Models
In order to leverage the City's existing data to
the maximum extent practicable, CDM will
modify the existing NFCC and BB models to
develop the hydrologic analysis for those
areas within the ZONE A floodplain, as
shown on the Preliminary DFIRMs.
North Fork Catfish Creek ZONE A
The existing HEC -HMS model for the NFCC
ZONE A will be updated based on the current
conditions. The major updates could include
adjustments of sub -basin boundaries based on
4
SECTION 2: Scope of Services
the latest topographic data and the
incorporation of the NW Arterial Detention
Basin (record drawings to be provided by the
City), and potential runoff curve number
modifications to represent current land use.
This information will be updated to the extent
necessary to predict accurate flood hazards
within the portions of the watersheds
delineated in ZONE A.
CDM will update the NFCC model to reflect
the NW Arterial Detention Bason so that the
full benefits of the basin can be quantified and
reflected in the revised flood maps. CDM
assumes that the City will provide contract
plans and the stage storage relationship for the
NW Arterial detention basin. We have
assumed that the updated HMS model can be
adjusted to match flows in the adjacent
detailed study reach on Catfish Creek which
will be a FEMA review requirement.
Bee Branch ZONE A
The existing HEC -HMS model for the BB
ZONE A will be updated based on the current
conditions. The major updates will include
potential modifications to the sub -basin
delineations, incorporation of the Carter Road,
32nd Street and 16th Street Basins and any
required land use modifications.
Hydraulic Models
CDM will develop hydraulic models of the
NFCC and BB for the portions delineated as
ZONE A on the Preliminary DFIRMs. We
have assumed steady -state HEC -RAS on
Catfish and the upper reach of the Bee Branch,
and unsteady SWMM on the lower reach of
Bee Branch and Kaufmann.
North Fork Catfish Creek ZONE A
Based on the findings from Task 1, the existing
HEC -RAS model for NFCC will be updated
and revised to reflect collected survey,
construction plans, and as -built information.
The revision will be performed so that the
completed model complies with FEMA
standards and requirements. At the
downstream end of the model, CDM will
utilize the 100 -year water surface elevation
from the effective study as the downstream
boundary condition.
Bee Branch ZONE A
The existing XP -SWMM model for the storm
sewer and downstream portion of BB ZONE A
will be updated based on the findings from
Task 1. New HEC -RAS models will be
developed for the open channel system
upstream of the 32nd Street Detention Basin
based on field survey data to obtain channel
cross sections and hydraulic structure
geometry in this reach. The Bee Branch
SWMM model will be extended to include
Kauffman Avenue and will incorporate final
flows from the HMS model. Cross sections
will be obtained to represent overland flow
paths along Kaufmann based on field survey
and topographic data. The overbank portion
of the cross sections will be developed using
the recent topographic data provided from the
City.
Establish Base Flood Elevations (BFEs)
Before establishing the BFEs, the hydraulic
models will be validated with the available
high water mark and historic flood data from
the City. After the validation, the hydraulic
models will be run for 100 -year storm to
establish BFEs. The BFEs will then be used for
developing the 1- percent annual chance
floodplain boundaries for the portions of
NFCC and BB watersheds.
The QA /QC task leader will perform reviews
at various steps within Task 2. This includes
reviewing the hydrological and hydraulic
updates and revisions to the models, the
completed models, and the validation process
and results. With CDM, QA /QC is not an
afterthought, but an intrinsic component of all
we do.
5
SECTION 2: Scope of Services
Task Deliverables:
• Draft report section on the development of
H &H models and results from the
hydraulic model runs
Task 3 — Floodplain Workmaps
One percent annual chance floodplain
boundaries will be prepared for the study
areas of NFCC and BB watersheds. CDM will
produce these boundaries using an automated
floodplain delineation process using HEC-
GeoRAS and GIS application tools. This
process compares a ground surface DEM to a
water surface DEM using standard ESRI
ArcGIS functionality to determine the extent
of the floodplain boundaries. The water
surface DEM will be created using the
hydraulic model results transferred to GIS by
using HEC- GeoRAS.
However, application of these automated
mapping tools does not produce final,
acceptable floodplain delineations. As part of
our standard floodplain development process
for LOMRs, CDM compares the created
floodplain to the model results, identifying
and correcting areas where the automated
process made errors. In addition, corrections
to the modeling are sometimes necessary after
reviewing the created floodplain. There may
be locations identified in the model where
storage areas should be expanded, or
structural and roadway overflows refined.
This is especially true in the lower Bee Branch
area where flow is limited in its overland flow
paths and is influenced by a number of factors
that are driven by the ground topography, the
volume of flood water, and the extent of the
floodplain storage. Our final delineation will
be reviewed by our QA /QC reviewer to verify
that our delineation is represenative and
acceptable to FEMA. This comprehensive
approach reduces technical comments and
helps to expedite the FEMA review process.
Task Deliverables:
• Preliminary workmaps of 1- percent
annual chance floodplain boundaries.
CDM
• CDM will meet with the City's
engineering staff to review the results of
the hydraulic models and the preliminary
1- percent annual chance floodplain
boundaries prior to beginning preparation
of the LOMR notification letters and
application.
Once the City has approved the floodplain
delineations, CDM will prepare a property
owner notification letter that the City will
send to all affected property owners where the
floodplain has changed as per FEMA
regulations. This will include all owners
within the revised ZONE AE floodplain, since
establishing the BFEs requires notification.
The City will be responsible for mailing all
letters via certified return receipt, per FEMA
LOMR requirements, and providing copies of
these return receipts to CDM.
Task 4: Preparation and Submission of
LOMR Application
CDM will prepare Letter of Map Revision
applications in accordance with MT -2 form
instructions. The LOMR application packages
will be reviewed for completeness by CDM's
LOMR task leader and our QA /QC reviewer
have experience with reviewing and
submission of LOMRs for several states. For
this task, the following items will be prepared
and submitted to FEMA:
• Completed MT -2 forms for the flooding
sources seeking a LOMR. The three forms
include the Community Concurrence
Form, the H &H Form, and the New
Structures Form.
• City of Dubuque concurrence of LOMR
application.
• Report describing scope of study, H &H
technical memorandum and all supporting
data used in the analysis (i.e. survey data
and structure plans). In addition, this
report will discuss the schedule of the
LOMR review and approval as compared
to the Preliminary DFIRMs becoming
6
SECTION 2: Scope of Services
effective. CDM would recommend that the
LOMR be reviewed and approved per the
goal of becoming effective the day after the
DFIRMs become effective.
• Hydrologic and hydraulic models
representing existing conditions of the
NFCC and the BB for the area of revision
as described in Task 2 in digital and paper
format.
• Workmaps representing the 1- percent
annual chance floodplain boundary for the
area of revision overlaid with topographic
contours and effective floodplain
boundaries. All modeled cross sections
and roads will be included on the
workmap for easy reference to the
hydraulic model. Per FEMA requirements,
this workmap will include the topographic
contours used in the analysis and
mapping, modeled cross sections, model
nodes and links, channel reaches,
stormwater facilities, and roadway
crossings. In addition, the workmap will
include both the effective and preliminary
floodplain boundaries, and tie -ins to each
for the revised floodplain boundaries.
Although the intent of the LOMR is to
revise the preliminary floodplain
boundaries, the DFIRMs will not yet be
effective when the LOMR is submitted.
Therefore, showing both boundaries will
reduce comments by FEMA. CDM will not
revise the limits of the Zone X area
protected by the Mississippi River levee,
but will show this boundary on the
topographic workmap for informational
and tie -in purposes.
• Drainage area maps for including sub -
catchments as modeled in HEC -HMS
model.
• Annotated DFIRM at the scale of the
Preliminary, showing revised and
preliminary floodplain boundaries, and
how these boudaries tie together.
Once the above - mentioned items are all
prepared, CDM will compile two reports, one
for each watershed, including all information
listed above, as well as copies of the
notification letters, and submit these to the
City for acquiring all local signatures on the
MT -2 forms. Once all the signatures have been
received, and once all signed return receipts
have been collected, CDM would submit the
final LOMR application to FEMA for review
and approval. It is standard for FEMA to
initiate the review prior to receiving all the
return receipts from the property owner
notification; however, the LOMR will not be
approved until this step of the process has
been completed.
Task Deliverables:
• A LOMR package including MT -2 forms,
H &H technical memorandum, maps of 1-
percent annual chance floodplain
boundaries, annotated FIRM and all
supporting data used for H &H analysis.
Task 5: Coordination with FEMA
CDM will coordinate efficiently with FEMA's
LOMC reviewer for timely determination of
the LOMR application. As described in Task 4,
the LOMR application will be reviewed for
completeness by CDM staff to avoid
additional data requests. Once our FEMA
LOMR reviewer is identified, we will establish
contact to open a line of communication and
to determine if any additional information or
clarifications are required. This approach will
avoid any unnecessary delays associated with
initial questions or confusion regarding the
application. Any technical questions or back-
up data needed for LOMR review will be
provided promptly to reviewer. Further, we
will stay proactive in following up progress at
reviewer's end and address any questions or
concerns the reviewer may have over phone
and email to speed up process.

Section 3: Quality Assurance /Quality Control
Quality has been the cornerstone of CDM's
reputation for hall a century. The firm now
follows the principles of Total Quality
Management, or TQM. Our philosophy is that
successful quality management must pervade
every aspect of our organization and be
embraced on every project. From the smallest
study or environmental assessment, to the
most complex treatment facility design and
construction, quality management is fully
integrated into every CDM project task.
As part of this culture of quality management,
CDM has developed Quality Management
Procedures (QMP) manuals which provide the
procedures and guidelines to be followed in
the execution of all CDM projects. QMP -1, the
manual that applies to non - construction
activities, is the rule by which CDM measures
our QA /QC efforts. Furthermore, all CDM
project managers are legally bound to follow
this manual by corporate policy. In addition,
CDM conducts internal audits to routinely
ensure that QMP -1 is being applied correctly
and consistently. This commitment to our
internal quality management quality
procedures is a verification of our
commitment to provide all our clients with
high quality deliverables.
For FEMA projects, CDM has even further
developed its set of in -house procedures,
processes and methodologies to meet FEMA
ccM
requirements. In 2006, CDM developed an
internal quality assurance program for FEMA
projects so that our internal QA /QC processes
align closely with FEMA's standard quality
requirements. Team member Onur Celik,
C.F.M. is coordinator for this program, as well
as a co- author of internal FEMA program
procedures, which were developed to
encourage successful procedure development
efforts for hydrologic and hydraulic (H &H)
analyses, DFIRM production and project
initiation.
Our QA /QC task leader, Del Schwalls, will
serve as an independent reviewer during
project execution. His estimated involvement
by task is shown in Table 4 -1 demonstrating
his participation in each task through LOMR
preparation.

Section 4: Project Team Qualifications
One of the critical skills required of a project
team is the ability to gather, internally review
and submit comprehensive and complete
documentation associated with the LOMR
application. This will allow FEMA's review
process to proceed smoothly so that the City
can receive up -to -date floodplain maps.
