S = speed limit or 85th percentile speed
The City of Bozeman Engineering Department should be consulted for any
unusual transition conditions. Grade breaks greater than 1-percent are not
allowed when matching existing dirt or gravel streets.
8. The cost of offsite pavement transitions shall be borne by the developer,
F. MEDIAN TREATMENT
Median curbs should be integral curb and gutter(with spill curb) unless otherwise
approved. Medians less than eight (8) feet wide should be capped with M-4000
concrete a minimum of three (3) inches thick. Wider medians should be top soiled
and seeded with an approved seed mix. The minimum median width is 4 feet. All
medians or raised islands should be made clearly visible at night through the use of
adequate reflectorization and/or illumination. Flexible delineators shall be placed at
the beginning and end of all medians, and at the point of any horizontal alignment
change. All median curbs and island curbs shall be painted yellow with epoxy
paint.
G. ROADWAY SPECIFICATIONS
Following are the requirements of the minimum roadway surfacing standards:
Surfacip&. The pavement thickness design will be based on the current AASHTO
Guide for Design of Pavement Structures, or the current Asphalt Institute Manual.
Series No. I (MS-1) for thickness design. A Pavement Design Report, based upon
specific site soil data and design-year traffic loading conditions, prepared by a
Professional Engineer, or other qualified professional approved by the City
Engineer, shall be submitted to the City Engineer for approval prior to plan and
specification submittal if using the self-certification process or with the plans and
specifications if using the standard process. The design shall be based on at least a
20-year performance period traffic volume; however,the minimum design lane
Equivalent 18,000-1b Single Axle Load (ESAL) used in the pavement design shall
not be less than 50,000-ESAL. The minimum asphalt pavement thickness for any
new local roadway shall be three (3) inches. The minimum asphalt pavement
thickness for any new collector or arterial roadway shall be four (4) inches, A
41
minimum of six (6) inches of high quality untreated aggregate base shall be
provided for designs utilizing asphalt pavement over untreated aggregate base.
Where full-depth asphalt is designed, an adequate stabilizer lift shall be included,
consistent with unpaved roadway design practices, to provide a suitable sub-base
capable of withstanding the traffic required for the initial construction of the
roadway. ] [ie Clfy nuly re(,plire roL.ti-x]-abow,,s or Iraffic,

14. SIGNS and MARKINGS
1. Street identification signs shall be installed at all new intersections in
accordance with City of Bozeman Modifications to MPWSS. The design
Engineer should consider, and the City Engineer may require, regulatory
traffic control signs and pavement markings in accordance with the MUTCD.
Stop signs shall be installed on local streets when they intersect with any
collector or arterial streets.
2. Unless otherwise approved, all transverse markings, words and symbols, and
8" or larger lane line pavement markings shall be inlaid thermoplastic or pre-
forined plastic tape. All other markings may be either inlaid or preformed
thermoplastic or epoxy paint. The materials proposed for all markings shall be
specified on the plans.
3. Crosswalk markings should not be used indiscriminately. An engineering
study should be performed before they are installed at locations away from
traffic signals or stop signs. Mid-block crosswalks are discouraged,
a. All marked crosswalks for designated school crossings shall be
longitudinal.white bars ("City of Bozeman Type B" style). "School
Crossing" signs and "School Advance Warning" signs shall be
installed at all designated school crossings.
b. At stop or signal controlled intersections, marked crosswalks shall
be two 8" white lines, 8' apart typically, installed transverse to
traffic and in-line with sidewalks, if any ("City of Bozeman Type
A" style),
C. Marked crosswalks at uncontrolled intersections, and all mid-block
crosswalks shall be "Type B", with "Pedestrian Crossing" signs.
"Pedestrian Crossing Advance Warning" signs should be installed
if deemed warranted by engineering judgment.
d. Parking shall be restricted by the use of signs and curb markings
within 20 feet of crosswalks at a minimum, or longer based on
engineering judgment.
42
e. All crosswalk signs and advance crosswalk signs shall have a
fluorescent yellow green background.
4. All signs shall comply with the "Standard Highway Signs"book (FHWA),
S. Street name signs for publicly-maintained roadways shall consist of white
letters on a green background. Street name signs for privately-maintained
roadways shall consist of white letters on a blue background,
1. MONUMENTATION
1. Monuments in monument boxes shall be provided in new or reconstructed
streets at all. section comers, quarter comers, and sixteenth comers,
J. LIGHTING

mains shall not exceed 500-fect long. Temporary dead-end mains scheduled
for future extension may end with a blow-off in lieu of a fire hydrant.
6. Services
a. A water line is designated as either a service line or water main
based on its use, not its size. Generally, a line serving a single
building or facility is considered a service line; a line serving more
than one building, or intended to serve more than one building or
facility is generally designated a water main. The standard sizes of
service lines are 3/4-, 1-, 11/2-, 2-, 4-, 6-, or 8-inch. The minimum
size of a fire service line is 1-inch. The minimum size of a service
line :fit 1. k insWled f6f a single family r-esidentia4 lot is I", to allow
for the potential use of the domestic supply for a fire sprinkler
system.
b. Service pipe shall be type "K" copper for sizes less than 4-inch,
and ductile iron for services 4-inch and larger. Plans and
specifications prepared by a Professional Engineer licensed in the
State of Montana shall be submitted for 4-inch and larger service
lines.
C. The service stubs shall be installed in accordance with the COB
Standard Drawings for service lines. The service line stubs shall
be installed at the center of each lot unless otherwise approved by
the Water Superintendent.
d. No service line shall be extended into a building until an
"Application for Service" has been completed and a Plumbing
Permit has been obtained from the Building Department.
e. Backflow prevention devices as required by the Water
Superintendent shall be installed on each fire and domestic service
line. Meters will be installed inside the building by the Water
Department on all service lines except for fire service lines. Meter
pits shall not be used unless specifically approved by the Water
Superintendent.
f. All service connections shall be uniform size from the service line
tap to the building structure or structures unless other-wise
approved or required by the Water Superintendent. The Water
Department shall reserve the right to require a larger service
connection to any building, structure or development if the water
requirements when calculated by the fixture unit method, as
specified in the Uniform Plumbing Code, cause the service line
velocity to exceed ten(10) feet per second. Each service line and

tests have passed and the test results have been submitted to the Water Department,
open all curb stops in the presence of the Engineer to assure the service lines are
flushed and all corporation stops are open. All main line valves are to be operated by
Water Department personnel only.
C. Service line installation from the end of the stub into the building shall be as per City
of Bozeman Standard Drawings 02660-12 or 02660-15. Service lines shall not be
installed from the end of the stub into the building until the main line has been
accepted by the City and placed into service. The water service line from the stub
into the building may be reduced in size, however the sire reduction must be made
within 18"ofthe curb stop or outside valve. Connections to existing stubs(either for
domestic or fire service)that have remained dormant or unused longer than 6 months
may require re-flushing or disinfection at the discretion of the Water Superintendent.
prior to being placed into service. The Water Superintendent may require
bacteriological testing to assure that the dormant line has not become contaminated.
3.9 TAPPING Revise this section as follows;
A. Tap the newly installed water mains unless specified otherwise. Provide aminimum
distance of 1.8" between service taps. The City of Bozeman Water Department will
tap any existing water mains. For taps on existing mains, the Contractor is
responsible for scheduling and coordinating with the Water Department. The
Contractor will be charged a fee for each tap made by the "Water Department. All
taps on existing mains require tapping saddles and corporation stops to be supplied.
and installed by the Contractor prior to tapping of the main by the Water Department.
B. Perform tapping using an approved tapping machine using clean, sharp drill taps
and/or shell cutters. 3/4-inch and 1-inch taps may be made directly into the barrel of
ductile iron pipe without using service saddles. Direct tap into the pipe barrel to the
depth exposing a maximum three threads of the corporation stop. Taps greater than
1" on a 6" line require the use of saddle clamps. Taps 4"and larger to existing water
mains which are 4," and larger require the use of a tapping sleeve and valve.
