COMMISSION RESOLUTION NO. 4757
A RESOLUTION OF THE CITY COMMISSION OF THE CITY OF BOZEMAN,
MONTANA, TO AUTHORIZE ADDITIONAL FUNDING FROM THE 2012 TRAILS,
OPEN SPACE AND PARKS BOND FUND FOR THE BICYCLE AND PATHWAY TO
THE "M" AND DRINKING HORSE MOUNTAIN PROJECT.
WHEREAS, Resolution 4484 approved and authorized funding in the amount of
$600,000 for the Bicycle and Pedestrian Pathway to the "M" and Drinking Horse Mountain
project; and
WHEREAS, Commission authorized the City Manager to enter into a Grant Match
Agreement with the U.S. Department of Transportation's Federal Land Access Program; and
WHEREAS, the required federal National Environmental Policy Act public input
process and associated surveys and investigations were completed in order to develop a preferred
pathway alignment concept, which necessitated negotiations with five property owners along the
pathway corridor to obtain easements or rights-of-way; and
WHEREAS, due to the inability to secure all of the necessary easements, a revised
pathway alignment must be pursued; and
WHEREAS, the project partners and staff recommend pursuing a design alternative
which has an added cost of approximately$75,000.
NOW, THEREFORE, BE IT RESOLVED by the City Commission of the City of
Bozeman,Montana:
i
i
Section 1
Funding/Authority. The Commission hereby authorizes additional funding in the amount of up
to $75,000 from the balance of the 2012 Trails, Open Space and Parks Bond fund to cover the
additional costs for design and construction of the project as recommended by staff.
Section 2
Amendment to Resolution 4484. This resolution serves to amend Resolution 4484 as delineated
in Section 1 above.
PASSED AND APPROVED by the City Commission of the City of Bozeman,

ATTACHMENT A
TRAIL TO THEM AND DRINKING HORSE MOUNTAIN—ALTERNATIVE ALIGNMENTS
Trails, Open Space and Parks Committee Meeting— Dec. 22, 2016
City Commission Meeting— Feb. 6, 2017
3.0 DESIGN ALTERNATIVE 1
Design Alternative 1 uses the same typical section as the current design, and the same alignment for
approximately the first 800 feet(2563+00 to 2571+00).
From there, rather than shift north outside the existing right-of-way, Design Alternative 1 continues to
parallel the existing right-of-way line_ The profile is elevated to eliminate cut slopes that would extend
outside the existing right-of-way. Due to the elevated profile, retaining walls are required on the right(fill)
side for approximately 1250 feet to avoid filling the SH 86 roadside ditch(2574+00-2586+25).
Near the east end of the Lyman Creek property,the profile must be dropped to cross a drainage immediately j
east of the Lyman Creek property. To stay within the existing right-of-way, approximately 300 feet of
retaining walls are required on the left(cut)side(2584+25-2587+00).
Based on geotechnical recommendations, temporary construction slopes are limited to 1VAH during cut-
side retaining wall construction. The limited available right-of-way width and the temporary slope restriction
will require the use of temporary shoring to construct the cut-side retaining walls. Approximately'1350 feet
of pedestrian railing is required to shield retaining walls and steep fill slopes. A
Advantages for this design include minimal impacts to roadside drainage and a high degree of separation
from SH 86. Disadvantages include a high construction cost and high complexity of construction.
The estimated construction cost for Design Alternative 1 is approximately$2,620,000,
4.0 DESIGN ALTERNATIVE 2
Design Alternative 2 uses the some profile as Design Alternative 1. However, to reduce retaining wall
needs, the typical section has been reduced to an 8-foot paved path with no shoulders. This allows the
alignment to be shifted closer to the existing right-of-way line.The reduced width and alignment shift results
in approximately 250 feet of fill retaining walls(2579+50-258'1+75),300 feet of cut retaining walls(2584+25-
2587+00), and 1150 feet of pedestrian railing to shield retaining walls and steep fill slopes_ Temporary
shoring will be required to construct the cut-side retaining wails. j
i
Advantages for this design include minimal impacts to roadside drainage and a high degree of separation
r
from SH 86. Disadvantages include a high construction cost, high complexity of construction, and a
reduced path width.
The estimated construction cost for Design Alternative 2 is approximately$1,020,000.
5.0 DESIGN ALTERNATIVE 3
Design Alternative 3 uses the some typical section as the current design, and the some alignment for
approximately the first 800 feet(3563+00 to 3571+00).
From there,the alignment shifts toward SH 86 and the profile is set at approximately the same elevation as
the highway. A minimum '10-foot separation is maintained from SH 86,as requested by MDT. This design
eliminates the need for fill-side retaining walls, but requires approximately 650 feet of cut-side retaining
walls to stay within the existing right-of-way corridor (3574+50-3575+75, 3576+25-3577+75, 3580+25-
3581+00,358-1+70-3581+80,3584+00-3586+75)_ Temporary shoring will be required to construct the cut-
side retaining walls.
The design of this alternative fills in much of the existing SH 86 roadside ditch for approximately 1250 feet
(3574+00-3586+50). A longitudinal drainage system will be needed to replace the existing roadside ditch.
No pedestrian railing is required.
Advantages for this design include a reduced need for pedestrian railing and a lower complexity of
construction than Alternatives f or 2. Disadvantages include a high construction cost, limited separation
from SH 86,and significant roadside drainage impacts.
The estimated construction cost for Design Alternative 3 is approximately$1,620,000_
6.0 DESIGN ALTERNATIVE 4
Design Alternative 4 uses the some profile as Design Alternative 3. However, to reduce retaining wall
needs, the typical section has been reduced to an 8-foot paved path with no shoulders. This allows the
alignment to be shifted closer to SH 86 while still maintaining the '10-foot separation. The reduced width
and alignment shift results in approximately 250 feet of cut retaining walls(3584+75-3586+75). Temporary
shoring will be required to construct the cut-side retaining walls.
The design of this alternative fills in much of the existing SH 86 roadside ditch for approximately'1250 feet
(3574+00-3586+50). A longitudinal drainage system will be needed to replace the existing roadside ditch.
No pedestrian railing is required.
Advantages for this design include a reduced need for pedestrian railing and a lower complexity of
construction than Alternatives I or 2. Disadvantages include a high construction cost, low degree of
separation from SH 86,reduced path width,and significant roadside drainage impacts.
The estimated construction cost for Design Alternative 4 is approximately$620,000.
