Report To: Honorable Mayor and City Commission
From: Jessica Ahlstrom, Water Conservation Specialist
Anna Rosenberry, Assistant City Manager
Andrea Surratt, City Manager
Subject: Amendment to Pump House Sketch Plan Materials for the Sunset
Hills Cemetery and Lindley Park Water Conservation Project
Meeting Date: March 4, 2019
Agenda Item Type: Consent Item
Recommendation: Authorize the City Manager to approve amended sketch plan materials for
the irrigation pump house to be constructed at Burke Park for the Sunset Hills Cemetery and
Lindley Park Water Conservation Project.
Background: The scope of the Sunset Hills Cemetery and Lindley Park Water Conservation
Project includes the construction of a pump house to be located near the Church Ave. parking lot
for Burke Park to pump surface water from Story Ditch to the Sunset Hills Cemetery irrigation
system where it will be used to irrigate the Cemetery and Park. A master site plan does not exist
for Burke Park, and thus the City is required to submit sketch plan materials for the pump house,
which detail site improvements and design plans and specifications. The pump house will be
located on the west side of the sledding berm at Burke Park to the east of Story Ditch. The east
side of the berm will be re-graded to ensure sledding safety in the wintertime.
On January 22, 2018 the City Commission approved sketch plan materials for the pump house
building to be constructed as part of this project. The initial design of the building was a
recommendation from the Recreation and Parks Advisory Board members and was estimated to
cost $95,000. The most recent cost estimate for this project indicated that total project costs
were much higher than the remaining project budget allowed for, requiring staff to value-
engineer the project to reduce costs. In doing so, it was important to maintain all aspects of the
project scope which contribute to project benefits. Thus, staff elected to have the pump house
building re-designed in order to remain within budget without impacting project benefits. Re-
designing the pump house building to include a smaller enclosure successfully reduced project
costs by $80,000, allowing staff to proceed with the project while staying within budget and
retaining all project benefits.

Project benefits include the conservation of treated water supplies, reduction of annual City
expenses associated with the cost of irrigation water, increased availability of domestic water
supplies during periods of drought, reduced safety risks to city staff associated with the existing
Bozeman Creek diversion structure, allowance for fish passage in Bozeman Creek and increased
instream flows for fish habitat. Total water savings realized upon completion of this project
equal 1,141 acre-feet per year. These savings include 1,082 acre-feet of additional water
supplies to be kept in Bozeman Creek, 34.3 acre-feet of treated water conserved, and 25 acre-feet
of groundwater supplies conserved.
Improvements to this site include a pump house enclosure and the reseeding of all native grass
areas disturbed during construction. Amended pump house design materials have been approved
by the Director of Parks and Recreation and have been presented to the Recreation and Parks
Advisory Board.
Alternatives: As suggested by the Commission.
Fiscal Effects: The Sunset Hills Cemetery and Lindley Park Water Conservation Project is
budgeted for in the approved FY-20 Capital Improvement Plan. An additional $300,000 in grant
funding from the Bureau of Reclamation’s WaterSMART Grant Program and $125,000 in grant
funding from the Department of Natural Resources and Conservation Renewable Resource Grant
and Loan Program has been secured.
Attachments: Amended pump house enclosure design plans and specifications.
