specifications.
3. EXECUTION
3.1 FES LIFTS
A. The number of lifts shall be the same along the entire project reach. Lifts shall
be 0.6 to 1 feet in height so that the top of bank elevation along the entire
project reach is met per the Plans. The elevation of lifts to be installed shall be
in accordance to the plans. Installation will be overseen by the engineer. Care
shall be taken to maintain integrity of fabric material, and minimize seams.
Disturbed banks within each river cut should be limited to the length of work
that can be completed within a single day to minimize the area exposed to
potential flooding.
B. Construction shall only occur during times of low flow to reduce any need for
dewatering. Perform all shaping of subgrade to the elevations, lines and
grades, as shown. Shape, trim, and finish slopes of channels to conform with
the subgrade lines, grades, and cross sections as shown. The subgrade shall be
graded to a smooth condition free from depressions and protruding rocks,
sticks, and other debris which may prevent a smooth application or that may
damage the fabric. Grout toe rock with soil grout sufficient for plant growth.
Care shall be taken to remove all objects that would interfere with application
or damage the coir fabrics. The finished subgrade will be approved by the
Engineer prior to placement of any new material.
C. Note that lifts are intended to curve as shown in the plans to maintain a more
naturalized bank appearance. Degree of curvature will be adjusted in the field
by the engineer, to match limits suitable to maintain the integrity of the FES
lift. Rigid forms, if used, may need modification to achieve this. Place forms
along the bank in locations to achieve the lines and grades shown on the Plans.
D. End transitions shall be secured by burying not less than five linear feet of
both the inner and out fabrics under the subgrade, properly staked and toed in,
then backfilled smooth for placement of rip rap over top. Transitions are
sensitive areas and some adjustments should be expected to ensure smooth and
stable transitions from rock to fabric occur.
E. Following completion of each fabric encapsulated lift bank installation, review
the installation for areas of loose fabric or locations of voids between fabrics
02260 - 3
and soil. Secure these areas with supplemental stakes or staples to ensure that
fabrics are tight and in solid contact with the underlying soil. The ENGINEER
will review fabric staking prior to project completing, and may request
additional staking in identified areas of loose fabric or voids.

Dear Ms. Poissant:
The lVlontana Department of Environmental Quali$ (DEO) reviewed your application for
{0J,Warer Quatity Certification received on December 7 ,2015. The fotlowing outtines
DEQ's final determination:
Description of the Proposed Project:
The project is to enhance Bozeman Creek through Bogert Park by altering the alignment
of the channel, expanding floodplain capacity, and establishing a vegetated ripariinconidor adjacent to the channel. The projectwill include construction of an overflow
swale to improve floodplain conveyance. An existing bridge will be replaced with a newbridge that will span the active channel and overflow channel. Approximately 270linear
feet of bank will also be stabilized in the project area by installing a rock toe and soilencapsulated coir lifts.
Beneficial Use Designations:
Bozeman Creek is classified as a B-1 water (ARM 17.30.623) and is to be maintained
suitatrie forddnking, arlinary, and food pocessing purposes after conventionaltreatment; bathing, swimming, and recreation; grorarth and propagation of salmonidfishes and associated aquatic life, waterfowl, and furbearers; and ag1cultural andindustrial water-su pply.
ln addition, ARM 17 .30.623 details the specific narrative water quality standards for B-1waters including:
"No increases are allowed above naturally occurring concentrations of sediment orsuspended.sediment, settleable solids, oils, or floatlng solids which will or are likely tocreate a nuisance or render the waters harmful, detrimental, or injurious to public health,recreation, safety, welfare, livestock, wild animals, birds, fish, or other wildlife.,,

Status of Affected Waters:
Bozeman Creek has not been assessed, so it is unknown whether it is supporting its
beneficial uses.
401 Water Quality Certification General:
Section 401 of the Federal Clean Water Act provides DEQ the jurisdiction to implement
the Montana Water Quality 401 Certification. 401 Certification is a federalistate
cooperative program that increases the role of the state in decisions regarding the
protection of nat-ural resources. The program gives ihe state authority to review
proposed activities affecting state waters and deny or place conditions on federal
permits or licenses that authorize if the proposed may violate state water quality
standards. State water quality standards were adopted to protect, maintain, and improve
the quality of water, including uses for public water supplies, wildlife, fish and aquatic life,
agriculture, industry, recreation, and other beneficial uses'
State water. quality standards inclulde the beneficial uses of a waterbody;therumeric
and narrative water quality criteria that are necessary to protect the uses of the
waterbody, and a nondegradation policy. ln the event beneflcial uses, such as aquatic
habitat oiaquatic life are-unavoida'bly impacted or tost, conditions of the 401 certification

RE:Confirmation Letter, Notice aI lnhnt (NOI) Number MTR7ffi1O8, BOGERT PARK
Dear CAROLYN POISSANT:
The Department of Environmental Quality (DEQ is acknowledging receipt on 6/9/2076 of your complete Notice
of lntent (NOl) for permit coverage under the January L,2OL3, General Permit for Storm Water Discharges
Associated with Construction Activity (General Permit). For administrative purposes, you have been assigned
permit number MTR1O65O8. Please include this permit number on any future correspondence with DEQ
regarding this site.
This letter acknowledges receipt of the complete NOI and does not provide a DEQ determination of the validity
of the information you provided. Your eligibility for coverage under the General Permit is based on the validity of
the certification you provided. Your signature on the NOI certifies that you have read, understood, and are
implementing all of the applicable requirements.
The General Permit requires you to implement the Storm Water Pollution Prevention Plan (SWPPP) and defines
inspection and record keeping requirements. Records defined in Part 2.5 are required to be maintained on-site
with the designated SWPPP Administrator. An electronic copy of the Permit and additionalguidance materials
can be viewed and downloaded at http:/ldeq.mt.gov/wqinfo/mpdes/stormwaterconstruction.mcpx.
Coverage under the General Permit remains effective until you submit a complete Notice of Termination (NOT).
Your signature on the NOT certifies that you have achieved final stabilization, removed your temporary Best
Management Practices, and have paid all applicable fees. Failure to submit a complete NOT will result in the
assessment of additional annual permit fees, which must be paid by the owner or operator.
Coverage under this General Permit does not waive your obligation to obtain coverage under other applicable
permits.
lf you have any questions regarding the requirements of the General Permit, please feel free to contact the

Subject: Bogert Park / Bozeman Creek Enhancement - Stormwater Pollution Prevention Plan Approval
Dear Mr. Ty Traxler,
I have reviewed your re-submitted SWPPP for the Bogert Park / Bozeman Creek Enhancement project and
am recommending the permit for approval. In addition, please understand that this is the Montana
Department of Environmental Quality’s (MDEQ) General Permit for Stormwater Discharge #MTR100000
(General Permit) and is subject to their review and inspection at any time. The City of Bozeman’s approval
does not guarantee compliance with the General Permit.
A few things to note:
1) Please install all erosion and sediment control measures before ground disturbance activities are
initiated.
2) Please ensure all parties involved with this project are aware of the contents, responsibilities, and scope
of this permit. Often times good permits are submitted, but they are not adequately followed through
with in the field. This often results in a discharge of pollutants to local waterways. Strong
communication is your number one tool to ensure this does not occur.
3) A City stormwater inspection may take place during this project. Inspections will include a document
review and a site tour examining installed erosion and sediment control measures. It is critical that
documents are continually updated, stored onsite, and the content is implemented to avoid violations
being issued by the City.
Please let me know if you have any questions.
Sincerely,
Frank Greenhill, Stormwater Program Technician
