Adopt Resolution #23-094 Approving Plans and Specifications and Authorizing Bids for Improvement Project #23-11, Trott Brook Crossing Sanitary Sewer Lift Station

Purpose:
Adopt Resolution #23-094 approving plans and specifications and authorizing bids for Improvement Project #23-11, Trott Brook Crossing Sanitary Sewer Lift Station.

Background:
On January 11, 2022, the City Council approved the Preliminary Plat for the Trott Brook Crossing residential subdivision.

On November 7, 2022, the City Council approved a Grading Agreement for the Trott Brook Crossing residential subdivision, allowing grading activities for the first phase of construction to begin.  The developer has since completed mass grading operations for the first phase of the subdivision, consistent with the approved preliminary plat

On March 28, 2023, the City Council approved the Final Plat and Development Agreement for Trott Brook Crossing.
 
The City enlisted Bolton & Menk to prepare plans and specifications to construct a sanitary sewer lift station to serve this development, along with future developments in this area of the City.
 
The title sheet from the final plans is attached for reference.  

Notifications are not required for this case.
 
Advertisements for bids will be run in the Anoka County Union Herald on Friday, April 28th, and on Friday, May 5th, 2023.   

Observations:
This is the same process the City followed to design and construct the trunk sanitary sewer lift station improvements that are now serving the Riverstone South residential subdivision. In addition, Bolton and Menk was the design engineer for the Riverstone South lift station improvements. This process worked well, and Staff recommends using the same design engineer for the Trott Book Crossing lift station due to Bolton and Menk's familiarity with the City's design standards and sanitary sewer system, and since most of the lift station design will be similar to the Riverstone South lift station, allowing Bolton and Menk to efficiently and cost-effectively prepare plans and specifications, advertise bids, stake construction and provide administrative assistance during construction.  Staff will present a construction services proposal from Bolton & Menk at the time bids are presented for Council acceptance.

Bidding the proposed improvements at this time will allow the City to serve the Trott Brook Crossings residential subdivision with the necessary municipal trunk sanitary sewer in 2023 as required to meet the proposed development schedule.  

Alternatives:
Alternative 1:  Motion to adopt Resolution #23-094 approving plans and specifications and authorizing bids for Improvement Project #23-11, Trott Brook Crossing Sanitary Sewer Lift Station.  

The engineer’s estimate of construction costs is $1,222,485.00.  Funding for these improvements are proposed to come from sanitary sewer enterprise funds.   

Staff recommends approving alternative #1 to align with previous City Council approvals related to the Trott Brook Crossing residential subdivision, and to ensure that the City will be able to provide the required trunk sanitary sewer when homes are ready to be occupied.
