HISTORY
The City of Bozeman , County seat of Gallatin County is located
in South central Montana . The estimated population as of 1968 is
16, 200 people. The city is presently served by two railroads , the
Northern Pacific and the Milwaukee Road, East West Interstate Highway
No. 90 and North South Highway U,S . No. 191 . In addition both Fron-
tier and Northwest Airlines serve the area thru Gallatin field, the City-
County Airport situated ten miles northwest of the city.
Bozeman is the center of a large cattle growing area which along
with agriculture formed the basic growth pattern of the area . Montana
State University , the largest and most rapidly growing unit of the Uni -
versi.ty system of Montana is located in Bozeman and is considered quite
a factor in the growth of the City.
The City operates under the Commission Manager form of govern-
ment governed by three Commissioners elected at large , one of whom is
elected Mayor. They appoint the City Manager who is responsible to the
Commission for the operation of all departments of the City.
The City of Bozeman has always recognized that good planning is
a prerequisite to orderly growth . This is borne out in the past planning
on sanitary sewer, storm sewer and water installations , streets and mu-
nicipal buildings .
The City under Ordinance No. 780 pursuant to Section 11-3262
1
Revised Codes of Montana 1947, created on March 30th, 1955 a City
Planning Board.
AREA WIDE PLANNING AGENCY
A . On August 21st, 1957, under Ordinance No. 802 by the City Com-
mission and by Resolution of the Gallatin County Board of Commissioners ,
a Bozeman City-County Planning Board was created. This Board has been
officially established to carry on area-wide comprehensive planning with-
in the urbanized area of Gallatin County. This Board has also been desig-
nated through appointment by the Gallatin County Board of Commissioners
as the agency to carry on county-wide water and sewer comprehensive
planning for all rural areas within the county. The City-County Planning
Board therefore has the authority to perform water and sewer planning for
100% of population of Gallatin County.
B. Information
1 . Membership

2 . Area of. Responsibility
The area of responsibility for comprehensive planning is that area lying
within four and one-half (4. 5) miles of the city limits of. Bozeman. The area
for water and sewer planning is the entire area within Gallatin County,
3 . Planning Staff.
Board negotiations were started immediately after reorganization to ob-
tain the services of a planner to develop a Master Plan of the area .
The Board, after interviewing several applicants , entered into a con-
tract, through the State Planning Board, with S . R. DeBoer and Company,
City Planning Consultants of Denver, Colorado to implement a Master. Plan .
This plan was very comprehensive in scope and was approved and adopted by
the City Commission December 3rd, 1958.
Mr. Lawrence C . Gerckens , Planning Consultant of Tempe , Arizona
was retained by the City-County Planning Board on July 25th , 1960 to up-
date the DeBoer Plan. Mr. Gerckens' plan consisted of more detail in
zoning, subdivision control and some revision to the Master Street plan.
His revision was completed March 27th, 1961 .
3
Theodore J. Wirth and Associates of Billings , Montana, and Consulting
Services Corporation of Seattle , Washington were retained by the Board in
1966 to bring the Master Plan up to date . The up-dating of the Master Plan
was financed in part with federal funds through the joint effort of the local
Planning Board and the State Planning Board. Under this study the land use
plan, arterial street plan, traffic study, Park Plan and Zoning were up dated„
This study was completed and adopted April loth , 1968 .
The firm of Thomas , Dean and Hoskins of Great Falls , Montana, was on
October 9th, 1967, retained by the Board to make an area-wide water and
sewer comprehensive plan for the rural areas within the County. The comple-
tion of this survey rests with the availability of matching Federal Funds from
the Farmers Home Administration.
The planning staff of the City-County Planning Board presently consists
of the Assistant City Manager, City Engineering Staff, Building Inspector and
the Chairman of the Montana State University Planning Committee .
The State Code of Montana, Chapter 38, Section 11-3825, provides the
source of financial support for City-County Planning Boards . Under this pro-
vision each of the governing bodies are allowed to levy not to exceed one—
half mill in their jurisdictional areas .
The monies derived from the Ad Volorem tax and federal 701 Planning
Grants have made possible the excellent progress of the planning.
The current City-County Planning Board Budget amounts to $4,906.30,
allocated as follows:
4
Salaries and Wages $ 800.00
Contractural Services 1000.00
Commodities 150.00
Current fixed Charges 200.00

SECTION I
WATER PI.AN
The existing water system has been developed as a result of sound
planning that has preceded each stage of development. The more recent
work on this system resulted from a report prepared in 1949 with an adden-
dum in 1951 and then updated in March , 1956 by Morrison & Maierle . These
studies included consideration of the water supply storage , transmission and
distribution. The majority of the recommendations in this report have been
accomplished.
1_._ _Evolution_of_Existing SZstem .
The present water supply for Bozeman consists of three separate systems
called (1) the Lyman Creek System, (2) the Bozeman Creek System, and (3)
the Hyalite Creek System . Each of these systems is noted on the "Water,
Supply Plan" in Section 1V.
The Lyman Creek System , located northeast of Bozeman, was secured as
the first source of water for the City. The system which was started by a
private company in 1889 and purchased by the City in 1899, consists of a
small earth fill dam and a concrete inlet structure in Lyman Creek. The Ly-
man Creek water has its source in a number of springs which are nearly al-
ways free of turbidity. The watershed above the intake is small, uninhabited
and is seldom traversed by humans . The City has the right to the first
238-3/20ths miners inches of flow in Lyman Creek . Only during very high
run-off per.ios does the stream exceed this flow. Average flows from Lyman
Creek approach 134 miners inches during the summer with a low of 50 miners
8
inches in the late winter. The water from Lyman Creek is treated with chlorine
and ammonia .
The Bozeman Creek System , located south of Bozeman, was developed
when the Lyman Creek supply became inadequate . This system consists of a
small intake and settling basin on Bozeman Creek about 6 miles south of the
City. Bozeman Creek is fed by run-off from its watershed. The water shows
some turbidity all of the time and considerable turbidity during high run-off.
The City has 1866 rights to 200 miners inches of the normal flow from Boze-
man Creek . By court ruling the City has preference to an 1865 right located
downstream from the City's intake structure. The City also has miners inches
of 1878 rights which are good for flood water only. During some years the
minimum flow in Bozeman Creek is considerably less than the 625 inches of
decreed water rights . As a result the full200 inches of Bozeman Creek rights
cannot be depended upon .
Mystic Lake is located about 7 miles above the Bozeman Creek intake
The Bozeman Creek Reservoir Company constructed an earth dam at the lake
outlet to provide about 1 ,480 acre feet of useful storage of water. The stor-
age is divided into 20 shares - each share amounts to 100 inches of water
over a period of 15 days . Six shares of storage are owned by the City of
Bozeman and this water is used to supplement Bozeman Creek water during
summer months . The other 14 shares are owned by farmers along Bozeman
Creek . The water from Bozeman Creek and Mystic Lake is treated with
chlorine and ammonia .
The Hyalite System located south of Bozeman was developed when the
9
Bozeman Creek and Lyman Creek supplies became inadequate to meet the
needs of the City. This system contains the T-Tyalite Reservoir operated by
Middle Creek Reservoir Association, whose members include the Montana
State Water Conservation Board, A diversion structure on 11yalite Creek,
which utilizes the site of an old mill pond as a pre-settling basin, consists
of a spillway and a head gate control . Also included in this system is a 21-
inch transmission line , approximately 20,000 feet lone from Hyalite, Creek
to the settling basin on Bozeman Creek . When this supply was developed,
settling facilities at Bozeman Creek were expanded to accommodate both
supplies
The City of Bozeman had contracted with the Middle Creek Reservoir
Association, prior to 1956 , for 1 , 050 acre feet of water annually from the
Hyalite Reservoir, Upon the recommendation of the 1956 report, an addi -
tional 1 ,460 acre feet annually was contracted to provide a total annual Ilya-
lite, storage of 2,510 acre feet.
Distribution reservoirs are provided at both Lyman Creek and in the Buze -
man-Hyalite combined creek systems , The Lyman Creek reservoir. is an open
cavity type reservoir and is located at an elevation of approximately 220 fee!
above ground level of the City Hall.
The water from the intake on Lyman Creek is carried in two 12-inch clay
tile pipes about 2, 700 feet where it connects to an 16-inch cast iron pipe .
The cast iron pipe extends about 1 ,400 feet to the reservoir. The top 3 or
4feet of the reservoir's concrete lining, which was cracked and spalled
prior to 1956, has been repaired . The capacity of the reservoir is about
10
5 .3 million gallons . An earth embankment around the reservoir slopes down
flush with the top of the sloping concrete lining. The 18-inch cast iron supply
line from the reservoir to Bozeman is about 2 miles long.
The Bozeman Creek reservoir is located about 2 1/2 miles south of the
City on Sour Dough Road , The reservoir is a prestressed concrete tank of.
4 million gallon capacity. The reservoir is at an elevation of approximately
300 feet above the ground level of. the City Hall. This elevation puts the
reservoir about 80 feet higher than Lyman Creek reservoir. The difference in
elevation is compensated by a booster pump station constructed in accordance
with the 1956 report, The booster station is located at approximately the inter-
section of Birch Street and North Wallace Avenue . Water is conveyed from
the small settling basins at the intake of Bozeman Creek and Hyalite Creek
through 18 and 21-inch transmission lines to the concrete pre-settling basins at
the junction of the Hyalite and Bozeman Creek lines . The water is carried
from the pre-sedimentation basin through an 18-inch and 21-inch lines to the
4 million gallon distribution reservoir. From the 4 million gallon distribution
reservoir the water is carried through the 18 and 24 inch transmission lines
to its confluence with the city distribution system on South Black Avenue
Treatment facilities include chlorination and fluoridation equipment.
Facilities are provided at the Lyman Creek distribution reservoir and the Boze-
man Creek distribution reservoir. This treatment is provided in addition to the
pre-sedimentation accomplished at the settling basins and the pre-sedimentation
tank .
The present water distribution system of Bozeman is supplied by Lyman
11
Creek distribution reservoir and the Bozeman Creek distribution reservoir.
The transmission lines from the Lyman Creek reservoir enter the distribution
system at the extension on Birch Street and North Wallace Avenue . The
transmission line from Bozeman Creek reservoir enters the distribution sys-
tem on South Black Avenue . The main loops in the distribution system con-
sist primarily of 10, 12 and 14 inch lines . The remainder of the distribution
system is 4, 6 and 8 inch lines .
Generally, the slope of Bozeman is from the south to the north with an
elevation difference between the south and north extremes of approximately
150 feet. To provide suitable pressure at the higher areas of the City, the
Bozeman Creek reservoir was constructed at an elevation of approximately 80
feet above the Lyman Creek reservoir. .
In accordance with the recommendations of the 1956 report, a 14-inch
line was installed westerly along College Street from Black Avenue to South
15th Avenue and northerly on 15th Avenue to Beall Street. A 1.0-inch .line on
Beall Street was extended from 15th Avenue to Rouse Avenue. In addition ;
a 10-inch line was installed on Koch Street and Curtis Street from 15th Avenue
to 7th Avenue . In recent years a 12-inch line was installed from Black Avenue
to Highland Boulevard on Kagy Boulevard to serve the Hyalite View Subdivision
and the 14-inch line on 15th Avenue has been extended to Durston Road, a 12-
inch line has been laid on West Beall from 15th Avenue to midway between
20th and 21st Avenue and a 10-inch line has been constructed on Durston Road
westerly of 15th Avenue to a point midway between 20th and 21st Avenues .

2 . Plan for Immediate Needs
In order to provide for the orderly development of a water system to serve
the rapidly expanding facilities of Montana State University and the steady
development of additions to the City of Bozeman, it is imperative that the supply ,
storage, treatment: and distribution be expanded and improved in the immediate
future.
The location of the existing facili.tes along with the planned improvements
and the areas to be served by the plan for immediate needs are shown on the
"Water Flan" in Section W. This plan includes the following features.,
Supply, Reconstruction of the inlet structures on Bozeman Creek and Lyman
Creek to replace deteriorating facilities and improve the operation of the system
Storage. Complete the landscaping of. the Bozeman Creek reservoir.
Treatment., The feasibility of chemical treatment to control turbidity is being
jointly studied by the City and Montana State University. Upon completion of
these studies , suitable chemical feed improvements will be installed to control
tutrbidity during periods of peak flow,
Distribution. Feeder and distribution mairis are to be installed in the areas
outlined on the "Water Plan" . Since per capita water consumption is relatively
high, the feeder system must be adequately sized to accommodate the use,
Operation. A program will be implemented to update the mapping of the
existing facility so that it shows current construction as well as the replacements
and corrective measures which are being made.
No charge is being made for service lines that are sized to provide fire
protection to individual buildings . A monthly charge for maintaining and sup-
plying those fire service lines will. be instigated,
13
ir Plan
In �}ddi.tlon to the service areas and layout of improvcrments shown on the;
"Wa€;,r flan" a "'Water Supply Plan" has been prepared to indicate the proposed
de v(,il.opme nt for both the 5 to 10 year plan and the long-range plan.
:ri to better conserve the present water- supply, a system, to use all
water stored in -the reservoirs is to be. developed, This sytem. will include control
,ral.vec, and motors at the distribution reservoirs and at the diversion structures
which crc, controlled by demand drawdown on the dist.ri.biation reservoirs . A te, ,
m eterli ng a ys t.em will control the operation of the valves by demand. Valves
and. rr.eter t,o be installed in the watershed storage reservoirs on Bozeman Creek.
and on Hyalite Creek will b(: incorporated in the long-range plan .
Wi�tey f.om Leman Creek is measured at the discharge pumps . These meters
\Avdl be r-eloa:aated to the reservoir to indicate the total water withdrawn from the,

SEWER PIAN
In the past, the City of Bozman has effectively utillzed sevver planning to
assur-c- that expansion and development of their sewer systern not., only served
tile existing conditions but 'that it accommodated antidj-,+ated future requi-e-ments
By combining advanced planning and timely construction projf.-!cts, the Ctty has
been able, to stnva a growing city in ac;,-,ordance, with state and fede'ral
ments . The adherenc�e- to these i-equirements has eliminated stye:-arn. pioll.ut,!.on

glans wers�, to constnict a new OUtfall, on. Norti-z Rous(-, Avenue� and ex-tend the
sewer discharge into the Last Gallatin proposal was submitted to the
State Board of Health in 1907. Instructions were returned stating that "the raw
sewage could't be discharged into the riven in such volumes to so pollute the
stream as to become hazardous to the health and welfare of residents in the
immediate area and the entire state" , The Board of Health recommended the use
of a septic tank sized to accommodate a population of 7, 500 people, As the
City continued to grow the tanks were converted to serve as settling basins
from which the raw sludge had to be removed and disposed of in sludge lagoons
By 1946 the improved standards for abatement: of stream pollution when
coupled with an increase in population, dictated that a study was needed to
ascertain the need for additional sewage 'treatment facilities , A r•sport was
prepared by Burns and McDonnell that proposed the construction of a primary
sewage treatment plant on North Rouse Avenue 'to remove sett:leablc,:� solids from
sewage and reduce the B .U.D. to acceptable stands , The improvements ?:r'lat
were made in 1948, included primary settling tanks , digesters to treat; the
sludge, and sludge drying beds . 'These improvements were designed t:o serve a
population of 15,800.
The coritinual growth of the City required the evaluation of the collec,t;ir�n
system in 1953 to relieve overloading of existing sewer lines, After completion
of preliminary studies by Morrison and Maierle , construction was proposed and
accomplished to provide a trunk line extending westerly from the sewage treat-
ment plant to North 8 th Avenue and Birch Street. From this point the line
extended southerly to eventually serve the geater portion of the campus of
Montana State University,
18
in 1959 Harold Hoskins & Associates prepared a report on the needs of the
City for updating sewage treatment: facilities and providing sewer line extensions
to serve the new growth areas , Modifications were proposed to provide for grit
removal, increase grinding facilities and general repair- wo,,k . Sewer line
extensions were proposed to serve the area to the north , the east., and the west:
of the City, The improvements to the sewage treatment plant were constructed
in 1,960 . During this same petiod a residential development was built in the
southeast part of the City without access to sewage treatment faci?i,fles „ To
provide treatment, sewage lagoons were constnuc.t,ed to meet, the immediate need
and are yet to be connected to the City treatment facilities . The following year
the interceptor lines ser-ving the areas southeast of. the City and south of the City
were constructed,
During 1963 the major portion of the interceptor lines outlined in the, 1959
report were constructed on the west side of the City and extended to serves the
proposed expansion of Montana State 'Univez•sity,
In 196E the City in an effort to meet: the requirements of the Water Pollr:.tdon
Control Administration and the State Board of Health , contracted Thomas 0 Dean
& Hoskins , Inc. to analyze the, treatment faoi,li,ti,es no,ce,s ary to meet the re
quirements of the Water Pollution Control. Administration and provide, c,ollpction
facilities to anticipated growth areas , This plan, which was comph-'Aed in 1,967 ,
proposed construction of a new activated sludge sewage treatment plant to be
located northwesterly from the City, interceptor- lines extending southeasterly
through the City, and an out:fall sewer from the existing plant to the proposed
new plant. Also outlined were proposed trunk sewerr5 to serve areas of future
19
growth outside of the Ci,ty� This plan has been adopted by the City and steps
have been initiated to carry out the first portion of the work, including the
treatment plant, the interceptor sewer and the out-fall. sewer.„
2. flan for Immediate bleeds
The "Sanitary Sewer flan" in Section IN shows the area being served and
the location of the major components of the existing system,, This plan also
indicates the location of the proposed improvements that area to be constructed
to meet the immediate needs , These planned i.mprovo ent.s include an activated
sludge: sewage treatment plant, an interceptor sewer and an outfall sewer,,
These facilities are to be constructed in accordance with the local plan pr-e-
pared in 1967„ The specific steps that have begirt taken to implement: this plan
include the retaining of Dain , Kalman & Quail as fiscal. agents and preliminary
negotiations for purchase of a plant site and sewer° line easements , An application
for a 30% construot'fon grant has been approved by the Water Pol.iution Contfol.

the project has been tentatively set for September. 10, 3.968
The construction of these improvements is a prereqursite to any fiutu're
expansion of the system. The 5 to 1.0 year plan cannot be undertaken. until, the
immediate needs are satisfied,
3 , Five to Ten Year Plan,,
The "Sanitary Sewer Plan" indicates the area into which sewer, lines are: to
be extended during the next 10 years . The local plan proposed cods trucJtion of
trunk sewer's to serge areas of anticipated growth . However, this plan did not:
dive any priorities for scheduling construction , Based on existing development.

and the potential health hazard the proposed trunk sewers are given the
following priority:
1 . Sour Dough Trunk
2 . Valley View Trunk
3. Willow Way Trunk
4 . Bridger Canyon 'Trunk
5. Hyalite Trunk
6. University.Southwest Trunk
This priority should be reviewed periodically to -ascertain if development
in any, given area has applicably changed the need for sewage collection in
that area. 'gunk sewers for these areas cannot be put into service until
completion of the improvements to be constructed--as"'part of the plan of the
immediate needs Annexation into the City of Bozeman will be required for each
of the areas before the work can begirt on the trunk sewers , Since the need for
sewerage collection is fast becoming critical in the first four priorities , a deta:lled
development schedule will be prepared as soon as the City has apprwral of the
revenue bond issue for construction of the immediate needs
Upon completion of each trunk sewer, late-ral sewers are to be const_►,U�:ted
to Provide collection in that area.
4 . Long-Kongo Plan,
The areas to ultimately be served under the long--range plan are shown on
the "Sanitary Sewer Plan" , It is anticipated that lateral sewers to serve the
trunk sewers listed in the 5 to 10 year plat► may be completed after the 10 year
period. The Far West 'Trunk sewer as proposed in the local plan is included
21
in the Long-Range Plan. Since this area is virtually undeveloped, we do not
anticipate a need for this trunk in the next ten years . Sewage from all the areas
in the long-range plan can be carried in gravity sewer lines to the site of the
proposed sewage treatment plant.
STORM DRAINAGE PLAN
The City of Bozeman has an extensive storm drainage system that has been
constructed as an intregal part of the street paving improvements . The City
has a long standing policy that no street is to be paved without adequate
drainage facilities . Storm water in sanitary sewer has thereby been held to a
minimum and street flooding during high intensity rainfall is not a serious
problem.
1 . Evolution of Existing System,
Storm drainage improvements were first constructed in Bozeman in 1908.
Among the first improvements were the intersection drains across Main Street
that move water from the south side of Main to the north side of Mendenhall
These units were installed from Grand Avenue to Rouse Avenue . The 10-inch
drainage line from College Street to Durston Road was also installed in 1908
The first storm drain to be installed to collect drainage and discharge into
an existing steam was installed in 1914 on North Wallace Avenue from Mat.n
Street to Bozeman Creek. The next major drainage system was extended from
Babcock to the alley north of Main Street on Third Avenue and then easterly
along the alley to Rouse Avenue and northerly on Rouse Avenue to Bozeman
Creek. This system was made up of 18 inch through 36 inch pipe and served
as a trunk storm drain for lines extending south into the southern part of the
22
C"ity..
The next improvements were the extensions of the: col."ecto*, .1ines, into
the southern section of Bozeman as far westerly as Sot,th 7tfi Avenae .
The last f'actl,ities constructed pri«z to 1950 were on South 8t.h Avenue
from Main Street to College Street, including extensions to 7th `.1"h!,
system discharged into an open ditch on North 9th Avenue
1n 1956 the City embar.k.ed on a major impro°rr ment pr,ograrn in the: aiea
south of Main Strea, west of South 8t:h Avenue: and +ryast of South 15th Avenue.
As part of this Improvement program, a special irri pro ve^rr ent d str,i.c;t. was set .;.p
to provide storm drainage facilities throughout the area , Included i,n this storm
drejinage program was a conduit on South 11th Avenue to pick up the sp.rilliq
water. in tfie, small creek, from, the campus at C1ol l.e-3ge Street,, ''hi.S corLdi.:it dis' -
t:harged into the: open di.t:c.h on 11th. Avenue: at; Curtis Street..
With the expanded development vvi.thi,n the City, the r,iee::d for st,.er�Ftt _.4,`IY.nc;
became more demanding., 1n 1958 the City prepared a storm drai.neig � ct d
,t.'lidy for that area rxor-t:h of Main Str(.,�at between 11th Avenue and Rowii:g Av,�,r°c.ie.
As a result, of this study, projects were initiated. to provide imu pro%rern.4r►t., in t',•h
area between North 3,1th and North 7th Avcn•1ues . During this same Pefl'od dY1
additional pairing and drainage disttict was set up be!twee n Noah '7th A•,renu(-: arid
Noat:h Grand Avenue with a discharge into the naviral drainage alour'Se:, exto.<nd gig
norther-ly on North 4th Avenue,
During 3.961 a paving di.stz-ict was set i.ip to gerve the area between Grand
Avenue and North ]douse Avenue , frorn Mendenhall Street to Peach StrF,$et.
drainage from the area was discharged at Peach Str.•f_,+:t, into Bozema.ra, Tj1,e
23
next major storm drainage improvement was to serve the area f;om Peach
Street to Tamarack Street between North Grand Avenue and Rouse Avenue. The
drainage from this area was discharged into Bozeman Creek at Tamarack and
Rouse Avenue. During this period the City continued its program of requiring
storm drainage with all paving improvements . Small projects scattered through-
out the City were constructed to include storm drainage facilities o
Many of the newly developing areas of the City have discharged into
Spring Creek as the most immediate natural drainage course serving the area.
As new areas continue to develop, the need for an overall drainage plan
extending outside the City limits became apparent. In 1967 a Housing and
Urban Development loan was obtained to prepare a plan to evaluate natural
drainage courses and establish the proper size of storm drain pipes to be in-
stalled in these drainage courses , The report was finished in the fall of 1967
and has been adopted by the City Commission as a local plan for, future instal-
lation of storm drainage. This plan will serve to insure that the proper and
adequately sized conduits are installed in streets o
2, Plan for Immediate Needs .
The immediate needs for storm drainage facilities in the City of Bozeman
include the extension of the drainage condu:lt on South llth Avenue from Curtis
Street across West Main Street, This will facilitate the development of South
1Ith Avenue and provide adequate drainage for the installation.
The drainage channel of Spring Creek from Kagy Boulevard to Garfield Street
will be developed to insure adequate drainage capacity,

The servic:;e areas to be improvE.d during the 5 to 10 year plan a-re, shown on
the. Storm Drainage, Plan map. These areas generally correspond to those are-'-is
designed as A through G in the local plan ,
4 . Long on e l'laxz Q
Storm drainage improvement for the long range plan will depend upon the
growth patterns . These growth patterris will be greatly ei:fec:cl by the availd-
bility of watiar mains and sanitary sewers , The areas shown fby- the �ong rang
plan therefore generally correspond W the water, and sanitary sewer- long range
puns

SECTION III
CAPITAL IMPROVEMENT PROGRAM
The present Capital Improvement Program included the sanitary sewer im-
provements for the immediate needs but did not include any other water or sewer
improvements . The Capital Improvement Program is hereby updated to reflect
the water and sewer plans as discussed in the previous sections and graphically
illustrated in Section IV.
The City of Bozeman owns and operates the water and sewer systems and
will expand and develop these systems in accordance with this plan to provide
services to users within the urban-wide area
Each utility customer is charged a monthly fee for water and sewer. usage
This fee is based on the amount of water used by each customer. 'These funds
are used by the City to operate , maintain, extend and improve the service they
are providing. A rate increase is anticipated to repay revenue bonds proposed
for construction of the sewerage improvements. The amount of this increase is
now being studied by Dain, Kalman & Quail, fiscal advisors for.• the City� Al-
though no increase in the water rates is necessary in the immediate tuture , the
continuing spiral of increasing costs will eventually dictate a rate increase.
Sources of revenue for capital improvements include general obligation
bonds., which are repaid by a mill levy assessed on the property within the
City; revenue bonds to be repaid from the water and sewer usage charge; sur-
plus monies from the water and sewer usage charge; special improvement dis-
trict bonds, which are assessed to the property benefited; county funds for
those projects serving both the City and County, State and Federal matching
26
funds for eligible projects .
The City may issue general obligation bonds upon vote of the people in
an amount equal to five percent of the assessed valuation, and levy taxes
sufficient to service that debt. The 1966-67 assessed valuation is $34,127,330
thereby permitting a bonded indebtedness of $1 ,706,366. The City has a
$432,000 bonded debt outstanding, thereby allowing $1 ,274,366 yet to be
borrowed.
The City may borrow an additional amount equal to ten percent of the
assessed valuation if it be for a water or sanitary sewage system. This would
permit an additional $3,412,733 in bonded debt, of which the City has out-
standing $899,000.
