2. Grant of Shared Stormwater Easement. The County grants certain easements and
agrees to undertake certain maintenance obligations that will benefit the Hidden Creek
Minor Subdivision for the joint construction, use and maintenance of stormwater
facilities, as further described below (the “Shared Stormwater Easement”).
The Shared Stormwater Easement is more particularly described on the attached Exhibit
A – Property Layout.
The County declares and grants a nonexclusive, perpetual easement to lay, construct and
maintain stormwater facilities, accessories and appurtenances for the purpose of storing,
treating and conveying stormwater.
This Shared Stormwater Easement shall be a perpetual easement and shall be superior to
and paramount to the rights of any of the Lot Owners, and the subsequent owner of said
properties and the respective servient estates so created. the County further state that this
Agreement is a covenant that shall run with the land, and shall be for the benefit of and
inure to the County, the Lot Owners, and their successors and assigns, their agents,
employees, tenants, and guests of tenants, and shall burden their respective parcels,
perpetually.
3. Required Maintenance of Stormwater Facilities. The Lot Owners shall directly pay the
Required Maintenance (defined below) costs for the stormwater facilities as required
hereunder. The Lot Owners shall pay a proportionate share of all Required Maintenance
for the stormwater facilities, which such proportionate share based on the ration of the
square footage of each Lot to the total square footage of all of the Lots. Required
Maintenance means any and all maintenance and repairs reasonably necessary to keep the
stormwater facilities in good repair, in a condition substantially similar to its condition
upon original installation, and keeping the stormwater facilities free of debris. Required
Maintenance shall include, but shall not be limited to …..The Required Maintenance
shall meet requirements in City of Bozeman Design and Construction Standards and
BMC §38.270.090, 40.04.700, 40.04.710, 40.04.720, and 40.04.850.

records of stormwater facilities installation, maintenance, and repairs for the life of the
development and shall be made available to the City of Bozeman Transportation and
Engineering Department upon request. Any failure to maintain stormwater facilities or to
correct deficiencies at stormwater facilities within a reasonable time after receiving
written notice from City of Bozeman or other enforcement agents may result in criminal
or civil penalties. Waste shall be disposed of from maintenance of stormwater facilities in
accordance with applicable federal, state and local laws and regulations.
The costs associated with the Shared Stormwater Easement are described on the
Shared Stormwater Easement and Agreement Hidden Creek Minor Subdivision
Page 3 of 7
attached Exhibit B – Shared Stormwater Easement Costs.
The maintenance plan associated with the Shared Stormwater Easement are described on
the attached Exhibit C – Shared Stormwater Easement Maintenance Plan.
The Lot Owners and their heirs and assigns shall be responsible for the maintenance and
repair of their respective portions of the Shared Stormwater Easement as documented in
this agreement and Exhibits A through C, including the underground and above ground
facilities.
The Lot Owners and their heirs and assigns shall hold the other party harmless from any
liability resulting from the use of the shared stormwater facilities for their respective
properties.
4. Cost of Required Maintenance.
Payment and Reconciliation. At any time there is more than one Lot Owner, than
within one hundred fifty (150) days after the last day of each calendar year, the Lot
Owners shall deliver to the other Lot Owners a statement (an “Annual Reconciliation
Statement”) containing the following information: (i) the maintenance performed; (ii) the
maintenance Costs; (iii) reasonable supporting data to evidence the maintenance costs
incurred; (iv) the allocation of maintenance costs as provided for Section 3 herein; and
(v) each Lot Owner’s share of the maintenance costs. Each Lot Owner shall pay any
amount owing within thirty (30) days after receipt of the Annual Reconciliation
Statement. The Lot Owners shall maintain, on an open-book basis, accurate records
regarding maintenance costs for the shared stormwater facilities to be shared and, upon
request, shall provide the requesting Lot Owner with a reasonable opportunity to review
such records on reasonable prior notice. If any Lot Owner wishes to challenge the
computations of actual, maintenance costs, the challenging Lot Owner shall give the
opposing Lot Owner written notice of the Lot Owner’s intent to audit the opposing Lot
Owner’s books and records pertaining to its operation and maintenance of the shared
stormwater facilities during the period in question. Any objections shall be made within
one hundred eighty (180) days following the date of receipt of the Annual Reconciliation
Statement or such objections shall be deemed waived. In the event that the audit
discloses any error in the calculation of the amounts payable by the challenging Lot
Owner, an appropriate adjustment shall be made forthwith. The costs of any such audit
shall be paid by the challenging Lot Owner unless it is finally determined as a result of
such audit that the challenging Lot Owner is entitled to a refund of more than five percent
(5%) of the final maintenance costs for such period, in which event the reasonable costs
of the audit shall instead be paid by the opposing Lot Owner.
Remedies for Non-Payment of Allocated Share. If a Lot Owner fails to pay its share of
Shared Stormwater Easement and Agreement Hidden Creek Minor Subdivision
Page 4 of 7
maintenance costs, within thirty (30) days of the date due, then in addition to such rights
and remedies provided for under Montana law, the defaulting Lot Owner shall be liable
for: (i) interest at a rate equal to the lower of the highest rate permitted by law from the
date the payment was due until the date the payment is received; (ii) a late payment
charge in the amount of Two Hundred Fifty Dollars adjusted for inflation, not as a
penalty, but as a way of defraying the costs that would be incurred in dealing with late
payments; and (iii) reasonable attorneys’ fees and costs of collection, including without
limitation court costs, if it becomes necessary to bring an action to recover the amount
due.
5. Enforcement. If a Lot Owner fails to carry out any of the obligations allocated to that
Lot under this Agreement other than payment of monetary obligations, or if a Lot violates
any covenants hereunder or threatens to violate such a covenant, the Lot Owners of any
other Lot shall be entitled to any remedy available at law or in equity, including the right
to restrain such violation or threatened violation by injunction, or to obtain a decree to
compel performance of the terms, covenants or conditions in default, it being agreed that
the remedy at law for a breach of any such term covenant, or condition (except those, if
any, requiring the payment of money) is not adequate.
6. Release/Hold Harmless/Indemnification. The County and any future Lot Owners, on
behalf of themselves and their assigns and successors, hereby release, indemnify, and
hold the City of Bozeman (City) harmless, its officials, agents, and employees (the
"Indemnitees") from and against any suit, cause of action, claim, cost, expense,
obligation, and liability of any character, including attorney's fees (to include costs and
salary of attorneys employed by or retained by the City), which are brought or asserted by
any person or entity, related to the shared stormwater facilities and duties and obligations
described in this Agreement.
In addition, the County and any future Lot Owners waive all claims against the
Indemnitees and their agents, insurers, and consultants, including all claims for
contribution or entitlement to special, incidental, indirect, or consequential damages
arising out of, resulting from, or in any way related to the duties and obligations
described in this Agreement or related to the shared stormwater facilities.
Such indemnity obligations shall not be construed to negate, abridge, or reduce other
rights or obligations of indemnity that would otherwise exist. The indemnification
obligations contained in this Agreement may not be construed to negate, abridge, or
reduce any common-law or statutory rights of the City which would otherwise exist. The
indemnity under this Agreement shall be without regard to, and without any right to,
contribution from any insurance maintained by the City.
Should the City be required to bring an action against the County or any future Lot
Owner to assert its right to defense or indemnification under this Agreement, the City
Shared Stormwater Easement and Agreement Hidden Creek Minor Subdivision

EXHIBIT C
Hidden Creek Shared Stormwater Maintenance Plan
The proposed stormwater facilities consist of shared and individually-owned systems
including:
• The landscape drain system serving Lot 1
• The retention basin to be owned and maintained by the owner of Lot 2
• The on-site subsurface retention systems serving Lots 1, 3, and 4
• The public street subsurface system serving Lots 1, 3, and 4.
The Stormwater Systems have been designed in accordance with City of Bozeman
standards and are described in the Storm Drainage Report and approved Plans. The
owner shall maintain copies of these documents as a record of required operating and
performance standards.
Each System will be monitored and maintained by the lot owner(s) individually or jointly
as identified for each type of system.
Monitoring and maintenance requirements will be provided in the owners’ association
documents and are excerpted here for review.
Stormwater Facilities Maintenance Schedule For All Systems (All Lots)
1. Site Housekeeping. (Continuously as needed)
The main cause of stormwater facility damage is poor site housekeeping.
Sediment tracked onto pavement can be washed into stormwater retention
basins and conveyance piping and damage these facilities. Trash can clog pipes
and inlet structures causing property damage.
• Keep sidewalk and pavement areas clean
• Pick up trash
• Restore damaged landscaping in order to prevent sediment runoff
2. System Monitoring. (Quarterly, except in winter)
The stormwater facilities shall be inspected quarterly to quickly identify small
issues before expensive damage can occur. In addition to regular monitoring,
the best time to inspect the performance of stormwater facilities is during runoff
events.
• Observe system during runoff. Look for ponding outside of retention
areas. This can indicate a clogged inlet or pipe.
• Inspect Subsurface system and Retention Basins
• Inspect Inlets, Manholes and Pipes
2
3. System Non-compliance
In the event that any of the stormwater facilities cease to comply with
performance requirements—either in operation or in any way that affects public
safety—the owner(s) of the Lot(s) served by that facility, as identified above, are
responsible for completing any repairs or replacements needed to restore the
system to compliant, safe, and proper working condition. All repairs or
replacements must return the facility to the performance standards shown in the
engineering record drawings recorded with the City.
Stormwater Facilities Maintenance Schedule For Lot 1 Landscape Drains
1. Lot 1 Landscape Drain Maintenance. (Quarterly)
The Landscape Drains provide initial infiltration of stormwater from recently
landscaped areas until the impacts of landscape construction have dissipated
and natural infiltration rates have been restored.
• Observe system during runoff. Look for ponding outside of drain areas.
This can indicate infiltration capacity has not been restored.
• Continue quarterly monitoring until there is no evidence of ponding in
landscaped areas during storm events.
Stormwater Facilities Maintenance Schedule For Lot 2 Retention Basin
2. Lot 2 Retention Basin Maintenance. (Quarterly)
The retention basin is designed to provide long-term sustainable treatment of
stormwater. However, with poor housekeeping sediment can clog these facilities
and reduce infiltration capacity. Proper and timely cleaning of incidental
sediment in these basins can prevent these facilities from being damaged. The
retention basin is intended to be vegetated, since the vegetation provides
microbiological communities that can treat common pollutants in stormwater.
Unhealthy vegetation can diminish the performance of these basins. The
landscaping of the retention basin shall follow typical landscape maintenance
guidelines. The vegetation on the bottom of the retention basin should not be
regularly mowed, since mowing can cause plant debris to build up in the basin.
• Remove sediment, trash, and debris
• Inspect for healthy vegetation
• Inspect for uniform ponding and water disappears in 3 days
3. Lot 2 Retention Basin Maintenance. (Annually)
The vegetation should be maintained annually to reduce plant debris build-up.
The retention basin vegetation should be cut to a height of 6” in the fall with the
clippings removed from the basin.
• Cut retention basin vegetation and remove clippings.
• Clean inlet piping or chases, remove sediment if present.
3
4. Lot 2 Retention Basin Maintenance. (Long-term)
If regular housekeeping and maintenance is not performed adequately, sediment
and debris can accumulate in the basin and reduce the required storage
capacity. If this occurs the basins should be excavated back down to original
plan grade.
• Hire a contractor to return basin(s) condition to initial design found on City
engineering plans.
• Dredge basin if sediment build-up is greater than 3”
Stormwater Facilities Maintenance Schedule For Lot 1, 3, and 4 Subsurface
Retention System (on-site)
1. Lots 1, 3, and 4 Subsurface Retention Maintenance. (Quarterly)
The Subsurface Stormwater Retention System is designed to capture sediment
and debris and requires regular monitoring and periodic maintenance to remove
sediments and debris. If this sediment and debris is not periodically removed, it
can cause undesired ponding and clogging. The stormwater retention system
consists of manhole structures and underground chambers. These components
need to be inspected quarterly, except in winter, and cleaned if required.
• Inspect for sediment or debris in the manhole structures and remove if
present.
• Check for damage, repair as needed
• Maintain records of quarterly inspections and cleaning and provide
records to the City upon request.
2. Lots 1, 3, and 4 Subsurface Retention Maintenance. (Annually)
The Subsurface Retention System requires a more intensive inspection annually
to check sediment depth in the Isolator Row.
• Inspect Isolator Row infiltration chambers through inspection ports for
sediment accumulation. Sediment depth less than 3” is acceptable.
Sediment depth exceeding 3” requires removal by a cleaning service.
3. Lots 1, 3, and 4 Subsurface Retention Maintenance. (Long-term)
If regular housekeeping and maintenance is not performed adequately, sediment
and debris can accumulate in the underground chambers and reduce the
required storage capacity. If this occurs the owner shall consult with an engineer
to determine the work required to restore the system to original intended
performance.
• Hire an engineer and contractor to return system(s) condition to initial
design found on City engineering plans.
4
Stormwater Facilities Maintenance Schedule For Lot 1, 3, and 4 Subsurface
Retention System (off-site)
1. Lots 1, 3, and 4 Subsurface Retention Maintenance. (Quarterly)
The Subsurface Stormwater Retention System is designed to capture sediment
and debris and requires regular monitoring and periodic maintenance to remove
sediments and debris. If this sediment and debris is not periodically removed, it
can cause undesired ponding and clogging. The stormwater retention system
consists of manhole structures and underground modules. These components
need to be inspected quarterly, except in winter, and cleaned if required.
• Inspect for sediment or debris in the manhole structures and remove if
present.
• Clean pre-treatment manhole to remove sediment and organic matter.
• Check for damage, repair as needed
• Maintain records of quarterly inspections and cleaning and provide
records to the City upon request.
2. Lots 1, 3, and 4 Subsurface Retention Maintenance. (Annually)
The Subsurface Retention System requires a more intensive inspection annually
to ensure sediment has not been deposited in the underground modules.
• Inspect modules through inspection port for sediment accumulation. If it is
observed that sediment has been deposited in the modules, more frequent
cleaning of the pre-treatment manhole is required.
3. Lots 1, 3, and 4 Subsurface Retention Maintenance. (Long-term)
If regular housekeeping and maintenance is not performed adequately, sediment
and debris can accumulate in the underground modules and reduce the required
storage capacity. If this occurs the owner shall consult with an engineer to
determine the work required to restore the system to original intended
performance.
• Hire an engineer and contractor to return system(s) condition to initial
design found on City engineering plans.
