INTRODUCTION
This memorandum requests the City Council conduct a public hearing for the Twin
Ridge Sanitary Sewer Extension and Lagoon Abandonment Project.
BACKGROUND
In 1998 the City began to extend sanitary sewer along Granger Creek, for the Dubuque
Technology Park development. The Granger Creek Interceptor Sewer (GCIS)
extension consisted of the Granger Creek Pump Station and approximately 17,600 LF
of both 20 inch and 18" diameter pipe. In 2015, the City extended the interceptor sewer,
continuing along Granger Creek and U.S. Highway 151/61, to the Dubuque Regional
Airport. The GCIS extension increased the sanitary Sewer Shed 4 to approximately
6,300 acres.
Since the GCIS and the extension to the Dubuque Regional Airport has been
completed, several adjacent areas in or near Key West have connected to the City's
sewer system, such as Table Mound Mobile Home Park, Kerrigan Heights Subdivision,
Truck Country, a portion of Twin Ridge Subdivision, and Silver Oaks Subdivision.
Tamarack Business Park and the City's Crossroads Industrial Park, along with other
adjacent parcels, are also able to be served by GCIS.
The City of Dubuque submitted a facility plan, based on the results of an intensive
evaluation of the existing interceptor collection and pumping systems that convey
sewage to the Water Resource Recovery Center (WRRC), to lowa Department of
Natural Resources (IDNR), in September of 2021. The facility plan identified three
improvement projects related to the Granger Creek Interceptor Sewer System: Granger
Creek Lift Station Capacity Improvements, Twin Ridge Sanitary sewer Extension and
lagoon abandonment and the Tamarack Sanitary Sewer Extension.
The Twin Ridge Sanitary Sewer Extension and Lagoon Abandonment Project will
extend the sanitary sewer gravity system and connect into the existing Twin Ridge
Subdivision gravity sewer system along with abandoning the existing lagoon system.
With the completion of this project the City will no longer need to permit, operate and
maintain the lagoon system and the parcel, currently occupied by the lagoon system,
would then be available for redevelopment.
DISCUSSION
The City selected Origin Design as the design consultant for this project through the
RFP Process. The sanitary sewer design is based on the approved IDNR Facility plan,
for the Granger Creek Interceptor Sewer Improvements. The sanitary sewer extension
will cross under U.S. Highway 151/61 , to the west, and connect into the existing Twin
Ridge Subdivision gravity sewer system. The lagoon system will be decommissioned
and abandoned in accordance with IDNR regulations.
A sanitary sewer connection fee will not be established for the service area since the
Twin Ridge Subdivision is currently served by a City owned sanitary sewer collection
system.
PROJECT SCHEDULE
The schedule for the project is as follows:
Initiate Public Bidding Process May 6, 2024
Publish Notice to Bidders, Advertise for Bids May 10, 2024
Publish Public Hearing Notice on Plans & Specifications May 10, 2024
Public Hearing on Plans & Specifications May 20, 2024
Receipt of Bid Proposals (Bid-Letting) June 6, 2024
Award Construction Contract June 17, 2024
Final Project Completion Date May 30, 2025
The award of the Contract may be delayed pending approval from the lowa Financing
Authority (IAF) and lowa Department of Natural Resources (IDNR) construction permit.
RECOMMENDATION
I recommend that the City Council conduct a public hearing and approve of the plans,
specifications, form of contract and estimated cost for the Twin Ridge Sanitary Sewer
Extension and Lagoon Abandonment Project.
BUDGET IMPACT
The estimate of probable cost for the Twin Ridge Sanitary Sewer Extension and Lagoon
Abandonment Project is summarized as follows:
Descri tion Estimate
Plannin & Desi n $67,700.00
Construction $955,932.15
2
Contin enc $ 95,593.22
Contract Admin / Construction En ineerin $50,300.00
0.5% SRF Loan Origination Fees 5,847.62
Total Project Cost $ 1,175,372.99
All three of the projects identified in the facility plan are utilizing State Revolving Fund
(SRF) loan proceeds for design. Two of the three projects, the Tamarack and Twin
Ridge sewer extension projects, are utilizing SRF loan proceeds for Construction. The
construction of the third project identified in the Granger Creek Facility plan, Granger
Creek Lift Station Improvements, is funded utilizing a combination of a State Revolving
Fund (SRF) loan, for design and a 20% match toward a $1,000,000 grant through the
EPA Community Grants Program.
The Twin Ridge Sanitary Sewer Extension and Lagoon Abandonment Project is utilizing
the SRF loan program funding for both design and construction. The SRF loan is being
funded through multiple Fiscal Year appropriations as detailed below:
