RE: Bee Branch Creek Trail Phase 1 Project — TAP-2100(697)-81-31
INTRODUCTION
The purpose of this memorandum is to provide the City Council with information related
to the recommended concurrence for the Iowa Department of Transportation to award
the public improvement construction project for the Bee Branch Creek Trail Project —
Phase 1 Project, Iowa DOT Project No. TAP-2100(697)-81-31.
BACKGROUND
This project was originally bid to include an alignment around the Alliant Solar Field site
located at 12t" street. Engineering solicited bids through the Iowa DOT for the project on
January 19, 2022.
During the development of the original bid documents, Engineering staff developed in-
house concepts where the trail would cut across a portion of the site that contains the
Alliant Solar Field located at the end of 12t" Street. The property owner of this parcel did
not want the trail to cut across the site in an easement. Their concern was the trail
would impact future development opportunity for the parcel.
During the design process, the alignment was shifted off the property to accommodate
the property owner request and keep the trail on City owned land. Unfortunately, this
revised alignment required significant retaining wall work and protective railing to
accommodate the new trail alignment.
When bids were received through the Iowa DOT, it was very evident construction costs
would exceed current available funding if the project proceeded. Bids were formally
rejected at the City Council meeting on February 7, 2022.
A grant application was approved by the Iowa DOT on May 19, 2020, in the amount of
$420,000.
DISCUSSION
Engineering staff worked with Fehr Graham out of their Manchester, IA office to re -visit
the design and alignment of the trail. The consultant and staff worked diligently with the
1
Iowa DOT, EPA, US Army Corps of Engineers and Iowa DNR to re -design the project to
reduce costs. From the past bidding experience for this project, staff learned what items
were the costliest and where the most bid uncertainty existed. These items include the
retaining wall and railing required for the trail. Based on this feedback, construction
documents and the trail alignment were modified to reduce the uncertainty and reduce
costs. The realignment also allowed for no encroachment on AY McDonald property.
The project will include the construction of a PCC Concrete trail from 12t" Street, around
the Alliant Solar Field on 12t" Street over to Sycamore Street. The project will include
the following:
- 1587 LF of PCC Concrete Trail
- 878 SY of Reinforced 6" PCC Sidewalk
- 231 LF of Ornamental Metal Railing
- 3255 CY of Embankment
- 750 SF of Segmental Retaining Wall
