Michael C. Van Milligen, City Manager
Carter Road Detention Basin Project Initiation
Assistant City Engineer Gus Psihoyos recommends that a public hearing be set for
October 6, 2003 for bid award for the Carter Road Detention Basin Project.
Veenstra & Kimm, Inc. has finished the plans and specifications for the proposed
detention basin. The earthen dam will be approximately 350-feet long and 40-feet high
with 3:1 side slopes. As approved by the City Council in July, the dam principal spillway
will be a 15-inch conduit and a 24-inch gated conduit. The h[gh flow outlet is a 48-inch
diameter riser p~pe that is approximately 37-feet high. A 350-foot long asphalt access
road is included to provide access to the outlet structure for operation and maintenance
needs. In addition, the project includes the reconstruction of the sanitary sewer under
the proposed dam because the original sewer was not designed for the depth that will
result when the embankment is completed. The proposed sanitary sewer will be
constructed in such a manner to prevent future sewer maintenance needs.
While there is an outside chance that the detention basin could be functional prior to
spring 2004 rainstorms, the Engineering Department and V&K believe a completion
date prior to June 30, 2004 would result in a significant increase m the cost of
construction. However. the Engineering Department recommends that the project
include an incentive bonus for the contractor to complete all work prior to June 30.
2004. This bonus would amount to $750,000 per calendar day for each day the project
~s completed before the June 30~ 2004 date. The maximum incentive would be
$67 500.00 (90 bonus days). In addition, we are including a $750.00 liquidated
damages for every day beyond the June 30, 2004 deadline that the project is not
complete.
V&K is anticipating that the appropriate authorities will grant all permits by November
17, 2003. If permits are not in the City's hands and authorization for the contractor to
begin work is not granted by that date, the contract deadline and bonus incentive would
be adjusted accordingly.
Assistant City Engineer Gus Psihoyos is further recommending that a request be made
to IDNR for an out-of-order review to expedite this project.
I concur with the recommendation and respectfully request Mayor and City Council
approval.

Carter Road Detention Basin Project Initiation
INTRODUCTION
The enclosed resolutions authorize the bidding procedure for the construction of the
Carter Road Detention Basin.
BACKGROUND
In December of 2001, the City Council adopted the Drainage Basin Master Plan
(DBMP) produced by HDR Engineenng. The DBMP addresses drainage issues in two
major watersheds in Dubuque, the North Fork Catfish Creek and Bee Branch
watersheds, recommending over $24 million in improvements.
The first recommended improvement to be constructed was the NW Arterial Detention
Basin located in the North Fork Catfish Creek watershed. The detention basin was fully
operational prior to the spdng rainstorm of 2002.
With the adoption of the Fiscal Year 2004 Capital Improvement Budget, the City Council
established funding for the Carter Road Detention Basin in the Bee Branch watershed.
In May of 2003, the City Council approved the selection of Veenstra & Kimm, nc. to
provide engineering and design services for the Carter Road Detention Basin project.
In July of 2003 the City Council approved the outlet structure design for the Carter
Road Detention Basin.
DISCUSSION
Veenstra & Kimm, Inc. has finished the plans and specifications for the proposed
detention basin. The earthen dam will be approximately 350-feet long and 40-feet high
with 3:1 side slopes. As approved by the City Council in July, the dam principal spillway
will be a 15-inch conduit and a 24-inch gated conduit. The high flow outlet is a 48-inch
diameter dser pipe that is approximately 37-feet high. A 350-foot long asphalt access
road is included to provide access to the outlet structure for operation and maintenance
needs. In addition, the project includes the reconstruction of the sanitary sewer under
the proposed dam because the original sewer was not designed for the depth that will
result when the embankment is completed. The proposed sanitary sewer will be
constructed in such a manner to prevent future sewer maintenance needs, n addition to
the sewer that is immediately ,mpacted by the embankment, other sanitary sewers
within the detention basin flooding limits will be reviewed to see if any modifications are
needed to prevent infiltration and inflow of stormwater into the sanitary sewer.
Depending on the condition of the existing sanitary sewer, some of the work might have
to be completed before the detention basin ~s fully operational. These costs will be
funded from the Infiltration and Inflow (l&l) Reduction Program with a balance of
$234,000.
Although engineering firms advised that a fall 2003 deadline is not doable due to
easement acquisitions; permitting from DNR and other associated agencies; and the
need for suitable construction conditions in the fall, the request for proposals outlined
the City's goal to have the detention basin operational prior to spring 2004 rainstorms.
Although V&K has been in constant contact with the DNR, getting input and feedback
throughout the design phase of the project, the DNR requires completed plans and
specifications prior to review. Plans and specifications will be submitted on September
3, 2003 with a request for an "out of sequence" review. It will take between 30 to 60
days to obtain a permit from the DNR and construction of the Carter Road Detention
Basin cannot proceed until the DNR permit is obtained. Attached is a letter to the DNR
requesting that this project be g~ven "out of order" review based on the flooding potential
that exists for the approximately 1,200 properties downstream of the proposed detention
basin. If an "out of order' review is granted, it could help the City reach its initial goal to
have the basin operational by spring 2004.
While there is an outside chance that the detention basin could be functional pdor to
spnng 2004 rainstorms, the Engineering Department and V&K believe a completion
date prior to June 30, 2004 would result in a significant increase in the cost of
construction. However, the Engineenng Department recommends that the project
include an incentive bonus for the contractor to complete all the work pdor to June 30,
2004. This bonus would amount to $750.00 per calendar day for each day the project is
completed before the June 30' 2004 date. The maximum incentive would be
$67,500.00 (90 bonus days). In addition, we are including a $750.00 liquidated
damages for every day beyond the June 30, 2004 deadline that the project is not
complete.
V&K is anticipating that the appropriate authorities will grant ali permits by November
17, 2003. If permits are not in the City's hands and authorization for the contractor to
begin work is not granted by that date the contract deadline and bonus incentive would
be adjusted accordingly.

The project will be funded from the storm sewer construction fund from the Fiscal Year

from the repdoritization of the Windsor Avenue Storm sewer project ($142,000) and
Terminal Street storm sewer project ($72,000) which engineering will recommend to be
re-budgeted. The remaining $18,849 will be funded from the General Storm Sewer
Construction Fund.
ACTION TO BE TAKEN
Engineering respectfully requests that the City Council establish the date of public
hearing, authorize the City Clerk to advertise for proposals through the adoption of the
enclosed resolutions, and endorse the "out of order" request to the DNR be submitted

CARTER ROAD DETENTION BASIN DAM
FLOOD PLAIN REVIEW
Enclosed 'ts a copy of the Joint Application for protecting Iowa Waters and two sets of
plans and specifications for construction of the earthen dam that will create the Carter
Road Detention Basra.
The City is aware that the review period for the dam could-take 90 days or more.
However, there is 1200 homes in the downstream valley that remain at risk of flooding
without this project.
Since the design is complete we would like to award the project this fall and have it
constructed as soon as possible. Our intent is to have the dam in place next spring if
we get a mild winter. Therefore the City of Dubuque respectfully requests an "out of
sequence" review of the plans and specifications for the Carter Road Detention Basin.
Thank you for your consideration of this request.
Sincerely,
