SUBJECT: Consultant Selection for the Design of the North Fork Catfish Creek
Sanitary and Stormwater Drainage Improvements Project
On September 10, 2007 the City received a proposal from IIW Engineers & Surveyors,
PC, WHKS & Co., and Veenstra & Kimm for the design of the channel, culvert, and
sanitary sewer improvements associated with the North Fork Catfish Creek Stormwater
and Sanitary Sewer Improvements Project. The Proposal Review Committee consisted
of Finance Director Ken TeKippe, City Engineer Gus Psihoyos, Leisure Services
Manager Gil Spence, Street & Sewer Maintenance Supervisor John Klostermann, and
Civil Engineer Deron Muehring.
Based on an independent, individual review and a collective discussion of the strengths
and weaknesses of each proposal, the committee unanimously concluded that IIW
Engineers & Surveyors, PC (IIW) of Dubuque, Iowa has the experience and expertise
required for the project and that IIW best responded to the objectives outlined in the
request for proposal.
The Proposal Review Committee recommends that the City negotiate and enter into a
contract with IIW Engineers & Surveyors, PC for the design of the North Fork Catfish
Creek Sanitary and Stormwater Drainage Improvements Project.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

SUBJECT: Consultant Selection for the Design of the North Fork Catfish Creek
Sanitary and Stormwater Drainage Improvements Project
INTRODUCTION
The purpose of this memo is to seek authorization to negotiate and enter into a contract
with IIW Engineers & Surveyors, PC (IIW) to design the channel, culvert, and sanitary
sewer improvements associated with the North Fork Catfish Creek Drainage
Improvements Project.
BACKGROUND
In December of 2001, the City Council formally adopted the Drainage Basin Master Plan
(DBMP) prepared by HDR Engineering (Omaha, Nebraska) for the Bee Branch and
North Fork Catfish Creek watersheds. HDR recommended several drainage
improvements that would all but eliminate roadway overtopping and flood damage along
the North Fork Catfish Creek between the Pennsylvania Avenue/John F. Kennedy Road
intersection and the Northwest Arterial.
With the adoption of the FY2008-FY2012 Five-Year Capital Improvement Program
Budget, $1,659,364 has been established for the North Fork Catfish Creek drainage
improvements outlined in the DBMP.
In March of 2004, the City funded an evaluation of the sewer referred to as the "Key
Way sanitary sewer system." Based on the recommendations of the study prepared by
Veenstra & Kimm, Inc., the City Council established $1,904,250 to up-size the Catfish
Creek interceptor sewer line from the University Avenue Extension at US20 to the
Northwest Arterial. The project consists of replacing the existing 12-inch diameter clay
sewer with a 24-inch diameter ductile iron sewer from University Avenue to Key Way
and replacing it with an 18-inch diameter ductile iron sewer from Key Way to the
Northwest Arterial. The City has completed a topographical survey from University
Avenue to Key Way.
On November 6, 2006, the City Council authorized the City Manager to submit an
application and subsequently approved the use of State Revolving Loan funds for the
project. In December of 2006 the State approved the City's application, placing the
project on the Iowa Finance Authority State Revolving Fund (SRF) loan program
intended use plan.
On August 20, 2007 the City Council authorized the release of an RFP for the design of
the channel, culvert, and sanitary sewer improvements associated with the North Fork
Catfish Creek Stormwater and Sanitary Sewer Improvements Project.
DISCUSSION
The various components of the North Fork Catfish Creek Stormwater and Sanitary
Sewer Improvements Project are outlined in Table 1. To design the improvements,
there are five complicating factors that the selected consultant must overcome:
1) The existing sanitary sewer that runs through the J. F. Kennedy
Road/Pennsylvania Avenue intersection is very deep and actually runs under
the Sherwin-Williams building. Therefore, tradition excavation would have
drastic implications to traffic flow through one of the City's busiest
intersections;
2) State Revolving Loan Funds have been established for the project. The
consultant should have some firsthand knowledge of the program to ensure
that the requirements of program are followed;
3) Federal (USAGE) and State permits will be required for the project. The
consultant should be aware of, and experienced with the various required
permits;
4) There is only a conceptual design for the North Fork Catfish Creek
improvements identified from Key Way to the Northwest Arterial. The
consultant should have experience designing creek restoration projects.
Although our main intent is to increase the flow capacity of the existing creek,
it will be a restoration project. As the creek flows through backyards, the
consultant will have to balance aesthetics versus maintenance requirements;
and
5) The existing right-of-way and easements may not be adequate to
accommodate the re-aligned sanitary sewer and the widened creek.
Therefore, the consultant must be able to balance the optimum hydraulic
sewer design versus property acquisition needs. We anticipate the need for
additional right-of-way.
The City received proposals from IIW Engineers & Surveyors, PC (Dubuque, Iowa),
WHKS & Co. (East Dubuque, Illinois), and Veenstra & Kimm (Moline, Illinois). The
proposal review committee consisted of Gil Spence, Leisure Services Manager; Gus
Psihoyos, City Engineer; Ken TeKippe, Finance Director; John Klostermann, Street &
Sewer Maintenance Supervisor; and Deron Muehring, Civil Engineer. Each committee
member reviewed the proposals independently. The committee then discussed the
strengths and weaknesses of each proposal to assess the likelihood of successfully
overcoming the five complicating factors listed above.
Based on the proposals, the committee unanimously identified IIW Engineers &
Surveyors, PC (IIW) as having the experience and expertise to be successful and that
IIW best responded to the objectives outlined in the requests for proposals.

The strength of IIW's proposal is the combination of local knowledge and experience of
the staff that will work on the City's project. Over the past twenty-five years, they have
surveyed and prepared development plans for many of the businesses along the creek,
businesses such as IHOP, Arby's, Steve's Ace Hardware, and the Dubuque Community
Church. In addition to private developments, they were involved with numerous city
projects along the creek, projects such as the University Avenue culvert extension and
sanitary sewer interceptor reconstruction, the University Avenue Embankment
Stabilization Project along the creek just west of the University Avenue Extension
Project, and the field survey for the Drainage Basin Master Plan prepared jointly with
HDR Engineering.
In addition to these strengths, the IIW team proposed for the City's project has
extensive experience with the State's State Revolving Fund (SRF) loan program that
the City intends to utilize for the project. And IIW has extensive experience working with
the U. S. Army Corps of Engineers and Iowa Department of Natural Resources to obtain
the necessary permits for the project.
As outlined in Table 1, there is $239,490 allocated for designing all of the
improvements. The fee for all three proposals is within the established budget for
designing the improvements.
RECOMMENDATION
I recommend that the City negotiate and enter into a contract with IIW Engineers &
Surveyors, PC for the design of the North Fork Catfish Creek Sanitary and Stormwater
Drainage Improvements Project.
BUDGET IMPACT
IIW's fee proposal of $212,585 is 11.2% under budget. The design of the improvements
will be funded from the following sources:
