Subject: |
The Trails of Manteca - Zone 36/39 Storm Drain and Sewer Trunk Pipeline Improvement Agreement |
Recommendation:
title
Adopt a resolution approving the Improvement Agreement for installation of a portion of the Zone 36/39 Storm Drain pipeline and a sanitary sewer trunk pipeline through the Trails of Manteca subdivision (east of the Woodward Avenue/Aplicella Court intersection); and authorize the City Manager or designee to sign and take all necessary steps to effectuate the Agreement.
body
Background:
The Zone 36/39 Storm Drain pipeline is designed to accommodate conveyance of stormwater flows south of State Route 120 to a new surface water discharge into the San Joaquin River at the west end of the City of Manteca (City) limit. On May 12, 2026, the City Council awarded the construction of the first phase of the outfall project consisting of installing the force main and outfall to the river. The second phase consists of installation of the storm drain pipeline from the Woodward Ave/Bella Lago Way intersection to the Woodward Ave/Aplicella Court. intersection and the third phase is comprised of constructing a new pump station.
The second phase of this work is required to be installed by the Trails of Manteca (Trails) development and will be routed through the Trails subdivision along the future Bella Lago Way, Cascade Drive, and Everest Drive to the Woodward Ave/Aplicella Court. intersection. It is prudent and most efficient that concurrent with the storm drain pipeline work the Trails developer also extend, along the same alignment, the City’s planned 10” sewer trunk line. This is a very cost-effective approach since both pipelines have the same nature of work and by constructing now on open undeveloped ground it removes the need for traffic control and road restoration work. The sewer and storm drain pipeline work are included in this improvement agreement.
Fiscal Impact:
The proposed improvement agreement includes a $3,166,795.08 reimbursement to the Developer paid from P.F.I.P. funds. Once the improvements are accepted by the City, the maintenance of the infrastructure will be the City’s responsibility.
