REPORT TO: Honorable Mayor and City Commission
FROM: Brian Heaston, Project Engineer
Craig Woolard, Director of Public Works SUBJECT: Integrated Water Resources Plan Implementation Plan
MEETING DATE: December 2, 2013
AGENDA ITEM TYPE: Action Item
RECOMMENDED MOTION: Having reviewed the information presented and considered
public comment and staff input, I move to accept the Integrated Water Resources Plan Implementation Plan. BACKGROUND: The Integrated Water Resources Plan (IWRP) was adopted by the City
Commission at a public hearing conducted on September 30, 2013. The adopted IWRP
contained an array of new water supply alternatives, operational improvements, and future
planning recommendations. The motion approving the IWRP directed staff to return to the Commission in December to present an implementation plan that provides details concerning the specific manner in which the adopted IWRP recommendations are proposed to be implemented.
The implementation plan is attached to this memorandum and sets forth implementation details
proposed to occur over the next three years.
FISCAL EFFECTS: Fiscal effects related to the implementation plan will be defined with the City’s capital improvement plan and updated annually as part of the city’s formal fiscal budget
process. The FY 2015 Capital Improvements Plan and annual budget will identify budget needs
for IWRP recommendation items adopted by the Commission.
ALTERNATIVES: Staff suggests any alternatives provided by the Commission take the form of amendments to the recommended motion presented within this staff memorandum.

IWRP Implementation Plan – December 2013
The Integrated Water Resources Plan (IWRP) was adopted by the Bozeman City Commission during a public hearing on September 30, 2013. The IWRP contains
a multitude of recommendations determined to best serve the City’s growing water supply needs. Once successfully implemented, these recommendations will
ensure Bozeman maintains an adequate water supply to serve the City’s projected water demands over the next 50 years.
The City’s 50-year water balance gap, which is the difference between 50-year high-growth projected demands and reliable supply yields, is 17,750 acre-feet.
This is the projected annual volume of water that must be secured in order to serve the City’s 50-year high-growth water needs and a population of roughly
140,000.
The IWRP provided specific recommendations for new water supply, operations and planning. This implementation plan provides additional detail on how the
recommendations adopted with the IWRP will be implemented. The tables on the following pages list specific tasks that will be accomplished to implement
IWRP recommendations over the next three years. During that time, new programs to improve water conservation practices and operational efficiency will be
implemented and evaluated. The detailed engineering and legal analysis necessary to determine the size, location, and cost of the new water supply capital
projects will also be completed. At the end of the first 3 years of IWRP implementation, sufficient data will have been collected for the Commission to evaluate
the need for and timing of new water supply projects. For reference, the overall 50 year water supply or conservation goal is also included in the table. Year to
year progress toward each overall goal will be communicated to the Commission in annual reports or in the form of formal Commission actions. Reports and
milestones for the Commission are also included in the table.
Implementation milestones will be posted to the IWRP webpage to provide a separate venue for interested citizens to track implementation progress. In
addition to regular updates to the web page, progress on implementation of the IWRP will be communicated to the community via presentations to local civic
groups, press releases upon the completion of major milestones, and an annual public outreach and education event similar to the Better Bozeman Project
WaterFest conducted this fall.
Completion of interrelated tasks is necessary to implement most of the major recommendations in the IWRP. For example, one of the water supply alternatives
recommended is construction of small impoundments in the Sourdough drainage to provide additional raw water storage. The ultimate decision to construct
this water supply alternative will depend not only on the engineering requirements and costs for construction, but also on the legal availability of water from the
Sourdough drainage and the projected need for additional water supply based on the community growth and the effectiveness of water conservation programs.
Tables 1 through 3 below respectively summarize implementation of the adopted new supply, operations, and planning recommendations.
The first priority for implementing the IWRP is developing a successful water conservation program. Conservation fills the largest proportionate share of the
City’s projected 17,750 acre-foot supply gap by providing 10,100 acre-feet of water savings. A water conservation specialist will begin developing the water
conservation program in January 2014. The first year of the program will focus on developing effective outreach and education programs targeting voluntary
indoor and outdoor water reduction. The conservation specialist will also be tasked with creating a robust water use tracking tool to quantify water savings. In
the following years, conservation will be expanded to include multiple incentive-based rebate programs. Code and rate-based conservation tools will only be
considered after a thorough evaluation of voluntary and incentive programs.
304
The capital intensive water supply alternatives are recommended in the IWRP (e.g. expansion and optimization of the Lyman Creek supply, installation of
groundwater wells, and construction of Sourdough impoundment(s)) all require additional detailed engineering analysis to define specific construction details
and costs associated with these alternatives before a decision to fully implement is made. The engineering required to evaluate the Lyman Creek and
groundwater alternatives will be initiated with the 2014 Water Facility Plan Update. Coupling the evaluation of these alternatives with the Facility Plan Update is
important because these alternatives must be analyzed in terms of how they interact and connect with the City’s existing water distribution infrastructure. The
facility plan update is anticipated to take up to two years to complete and will include these detailed engineering investigations as well as update the current
water distribution system model, proposed distribution system models, and analyze options for additional treated water storage. A separate detailed
engineering investigation is proposed for the Sourdough impoundment(s) alternative to be completed in conjunction with efforts to legally secure supplies for
storage behind the impoundment(s). Legal supply options to be explored include preparing a draft Department of Natural Resources Conservation (DNRC)
Change Application for the existing Mystic Lake water rights, utilization of existing Water Reservation 41H-70118, and/or additional surface water sources. The
change application will only be submitted to DNRC after sufficient details concerning the size, type, and location of the proposed sourdough impoundment(s) are
obtained from the detailed engineering investigation. The engineering investigation phase of the implementation plan is anticipated to take 3 years to
complete.
An administrative update to the IWRP is proposed to capture information acquired with the detailed engineering investigations, as well as update population
projections and the water supply and water demand analysis. Staff suggests reconvening the TAC to screen the updated alternatives against the qualitative
screening criteria initially developed for the IWRP as well as generally guide the update process. The IWRP update will culminate with a recommendation
concerning selection and implementation of capital projects for construction.
The implementation plan presented is intended to be dynamic and should be revisited annually to capture project milestones and project specific information
acquired over the course of the year.
