REPORT TO: Honorable Mayor and City Commission
FROM: Brian Heaston, Project Engineer
Craig Woolard, Director of Public Works SUBJECT: Authorize the City Manager to execute a $311,511 Professional Services
Agreement with AE2S to complete the Lyman Creek Water System Expansion Preliminary
Engineering Report for the City of Bozeman.
MEETING DATE: August 24, 2015 AGENDA ITEM TYPE: Consent
RECOMMENDATION: Authorize the City Manager to execute a $311,511 Professional Services Agreement with AE2S to complete the Lyman Creek Water System Expansion Preliminary Engineering Report for the City of Bozeman.
BACKGROUND: The adopted Integrated Water Resources Plan and Implementation Plan call
for enhancing the reliable supply of the Lyman Creek source. Current reliable supply provides 1,790 acre-feet per year; however, the city’s legally available supply in its current Lyman Creek water rights is 4,346 acre-feet leaving a significant margin for potential supply enhancement. A
unique approach to developing this additional supply will be completed with the preliminary
engineering report. The consulting engineer will study and evaluate the geology of the limestone
formation from which Lyman Creek emerges. The results of the study will inform development of detailed specifications for the drilling of exploratory wells into the limestone formation. If the wells produce, the reliable water supply of the Lyman Creek source will be bolstered and
potentially able to meet the amount legally available in the city’s water rights.
The firm of AE2S was selected as most-qualified to perform services for the project upon evaluation of requests for proposals received for the project. Scope and fee negotiations between AE2S and city staff pursued to develop the Professional Services Agreement (PSA) for the
project attached to this memorandum.
FISCAL EFFECTS: A budget of $311,511 is required to perform the scope of services negotiated in the attached PSA. Staff proposes to fund the project over two fiscal years. Work in FY16 will be limited to the geologic study and completion of well drilling specifications.
Budget for these tasks is $80,869. The exploratory well drilling operation will be funded in the
FY17 CIP at a current planned amount of $230,641. An amendment to the FY16 Operating and
Capital Budget for the city has been authorized by the City Manager in accordance with
authority granted to the City Manager to administratively amend the adopted budget pursuant to
Commission Resolution No. 4602, Section 4. The City Manager’s amended FY16 budget
created a new project for the Lyman Creek Water System Expansion Preliminary Engineering
Report within the FY16 Water Fund CIP and appropriates $80,869 from the Water Fund reserve to complete the geologic study and well drilling specifications components of the project.
Sufficient cash in the reserve was provided by Project W32 (1ine 18” water transmission main
from Sourdough Plant to Sourdough Tank) which was scheduled in the FY15 Water Fund CIP
but went unspent as the project was not undertaken.
ALTERNATIVES: As suggested by the Commission
