Commission Memorandum
REPORT TO: Honorable Mayor and City Commission
FROM: Kristin Donald, Finance Director
SUBJECT: Adopt the Storm Water Fund Capital Improvement Plan (CIP) for
Fiscal Years 2019-2023.
AGENDA ITEM TYPE: Consent
MEETING DATE: November 20, 2017
RECOMMENDATION: Adopt the Storm Water Fund Capital Improvement Plan (CIP)
for Fiscal Years 2019-2023.
BACKGROUND: Each year, the City Manager is required to prepare a 5 Year Capital
Improvements Plan and submit it to the Commission by December 15th. Similar to recent years
past, we are bringing the various parts of the plan forward as items on the Consent agenda. We
will be prepared to address questions, if they arise, at the public meeting.
The Public Works, City Manager, and other city staff met in October and November to develop
the attached Capital Plan for the equipment and capital needs of the Storm Water Fund.
Items of Note:
STRM13 – Annual Pipe Replacement – An annual program that provides funding for
the design and construction of various pipe rehabilitation, drainage, and treatment
projects that improve the structural integrity and conveyance capacity of the City’s
stormwater infrastructure network. Unplanned funds allow Staff to respond to
37
infrastructure needs that arise from reoccurring system inspection and partner with other
Public Works’ projects, such as local SID street reconstructions when approved.
STRM48 – Annual Pedestrian Ramp Replacement Program has been added to the
Stormwater Fund CIP at $100,000 per year. Costs will be split 50/50 with the Street
Maintenance Fund. Cost share is appropriate because typically pedestrian ramp
improvements also require replacement of stormwater inlets and catch basins. Having
funds available for the stormwater related costs of ramp replacement will increase the
number of ramps that can be replaced each year.
STRM39, STRM34, STRM31, STRM38- Mechanical Separation Units Downtown
Stormwater treatment- These are phases budget for FY19-FY22 that install stormwater
mechanical separation units near intersections.
Fiscal year 2017 revenues represent the first fiscal year where our rate-model is fully
implement for all 12 months. The changes in revenues over the past 5 years have been
driven by our implementation of the full rate model. We are basing our FY19-23 revenue
estimates on annual customer growth of 3% per year. This is similar to our most recent
Wastewater rate model. Actual revenues should grow depending on the mix of
impervious areas/existing infrastructure use as property is annexed and developed.
38
UNRESOLVED ISSUES: None.
ALTERNATIVES: As suggested by the City Commission. If the Commission does not
wish to adopt this schedule tonight, it can be scheduled for approval on a later agenda.
FISCAL EFFECTS: This step in the process has no fiscal effect. Once adopted, the
Capital Improvements Plan becomes the basis of the City Manager’s Recommended Budget for
FY18.

Stormwater TV Van Refurbishment
FY19 FY20 Unscheduled
$125,000
DESCRIPTION OF PROJECT
Refurbishment of existing Stormwater TV van routinely completed every 5 years to replace worn parts and remain consistent
with new technology. This equipment is critical in assessing structural failures in the City's underground stormwater system, and
allows the City to identify troubled areas and allocate resources to fix. This process significantly improves operation efficiency,
budget allocation, and project planning. Deferring this purchase would result in existing equipment to exceed their effective
lifespans, resulting in unexpected breakdowns and inefficiencies.
ALTERNATIVES CONSIDERED
Purchase a new TV Van at an estimated cost of $250,000.
ADVANTAGES OF APPROVAL
Provides for the timely replacement of critical maintenance equipment.

Mechanical Separation Units - Downtown Stormwater Treatment Phase 4
FY19 FY20 Unscheduled
DESCRIPTION OF PROJECT
This project includes the installation of three (3) stormwater mechanical separation units near the following intersections: N.
Rouse and E. Tamarack, S. Black and E. Cleveland, and S. Bozeman and E. Cleveland. Staff proposes to target these locations
because the roads, parking lots, yards, driveways, and drainage systems contained within their urban watersheds have a direct
connection to Bozeman and Matthew Bird Creeks, meaning no removal of stormwater pollutants currently occurs.
ALTERNATIVES CONSIDERED
Staff has not identified any alternative stormwater treatment approaches with comparable maintenance requirements, construction footprints,
and/or pollutant removal efficiencies, especially considering the large size of the drainage basins targeted.
ADVANTAGES OF APPROVAL
The three (3) units will treat stormwater flowing from 278 urban acres and collect over 17 tons of sediment, litter, oil, and metals annually.
Pollutant removal will improve public safety, help restore Bozeman and Matthew Bird Creeks’ aquatic habitat, decrease infrastructure
degradation, and provide the City a measurable step towards municipal stormwater discharge permit compliance.
ADDITIONAL OPERATING COSTS IN THE FUTURE, IF FUNDED
Stormwater Operations Personnel will complete maintenance quarterly, including the removal of collected debris using existing vacuuming
equipment. Once collected, Staff will temporarily store and dry debris at the City’s Stormwater Waste Management Facility before hauling to
the landfill for final disposal.
