AGENDA ITEM SUMMARY
FORT COLLINS CITY COUNCIL 20
SUBJECT
Resolution 2013-049 Authorizing the Execution of the First Amendment to the Intergovernmental Agreement
Establishing the Boxelder Basin Regional Stormwater Authority.
EXECUTIVE SUMMARY
The Boxelder Basin Regional Stormwater Authority (BBRSA) was established by an intergovernmental agreement
(IGA) between the City of Fort Collins, Larimer County and the Town of Timnath to fund and implement regional
stormwater improvements.
Staff recommends approval of the first amendment to the IGA in order to:
• Obtain approval of the member governments for the BBRSA to accept a loan from the Colorado Water
Conservation Board (CWCB) to fund the design and construction of the remaining projects;
• Authorize the BBRSA to determine and make minor revisions to properties within the Service Area of the
BBRSA by designating areas as “non-tributary areas”, and to grant fee credits to other areas within the Service
Area; and
• Establish a sunset provision such that upon completion of the Projects, payment of all debt incurred by the
Authority for the construction of the Projects, and agreement among the Members as to any continuing
obligation for operation and maintenance of any Authority projects, the BBRSA can be terminated.
BACKGROUND / DISCUSSION
On August 20, 2008, the City of Fort Collins, Larimer County and the Town of Wellington entered into an
intergovernmental agreement (IGA) to establish the Boxelder Basin Regional Stormwater Authority (BBRSA). The
BBRSA was established to fund and implement the regional stormwater improvements outlined in the Boxelder
Regional Stormwater Master Plan. The stormwater improvements benefit the citizens of Fort Collins through
protection of the health, property, safety and welfare of the city and by enhancing the ecological health of Boxelder
Creek.
It is in Fort Collins’ best interests to participate in the BBRSA in order to:
• Make already cost effective improvements more economical by sharing costs;
• Reduce substantial public infrastructure costs for road crossings;
• Equitably share the cost between participating agencies;
• Provide economic benefits by removing undeveloped lands from the 100-Year floodplain; and
• Provide a cooperative approach that initiates solutions to stormwater problems in Fort Collin’s Growth
Management Area (GMA).
The BBRSA has completed the design and construction of the Coal Creek Flood Mitigation Project and has
preliminarily designed the two remaining regional stormwater projects which consist of the East Side Detention Facility
(also known as the Gray Lakes Project) and the Larimer/Weld Canal Crossing Structure. Timnath (in conjunction with
its TDA) has entered into an Intergovernmental Authority with the BBRSA to participate in the funding of the remaining
projects.
The BBRSA investigated potential funding scenarios (i.e., pay-as-you-go, bonding, loan) and initially recommended
in 2011 to the member entities that a bonding approach be pursued. After additional research, the BBRSA determined
the most cost efficient method of funding the regional stormwater projects is by obtaining a loan through the Colorado
Water Conservation Board (“CWCB”). According to Section 2.05 (f) of the IGA, all member entities must agree to the
issuance of debt by the BBRSA.
May 21, 2013 -2- ITEM 20
On January 17, 2013, representatives from Fort Collins, Larimer, Wellington and Timnath as well as the BBRSA Board
of Directors met to discuss the latest estimated regional stormwater project cost estimates, the funding approach, a
potential sunset provision, the BBRSA stormwater fee structure, and potential revisions to the BBRSA service area
boundary. As a result of those discussions, the BBRSA developed a draft amendment to the IGA that will:
• Allow the BBRSA to accept a loan from the CWCB to fund the design and construction of the remaining
projects; and
• Authorize the BBRSA to determine and make minor revisions to properties within the Service Area of the
BBRSA by designating areas as “non-tributary areas”, and to grant fee credits to other areas within the Service
Area; and
• Establish a sunset provision such that upon completion of the Projects, payment of all debt incurred by the
Authority for the construction of the Projects, and agreement among the Members as to any continuing
obligation for operation and maintenance of any Authority projects, the BBRSA can be terminated.
FINANCIAL / ECONOMIC IMPACTS
The BBRSA has preliminarily designed the East Side Detention Facility (Gray Lakes Project) and the Larimer/Weld
County Crossing Structure. These are the two remaining projects needed to meet the goals of the Boxelder Regional
Stormwater Master Plan. Through preliminary design, the total cost of the two projects is estimated to be
approximately $9.9 million. The most cost efficient method of funding the projects (and lowest interest rate) is by
obtaining a loan through the CWCB. The anticipated interest rate of 2.75% for the CWCB loan is significantly lower
than an estimated interest rate of 4.0% for issuance of bonds. The BBRSA will obtain a 20-year loan; however, it may
be possible to pay it off in a shorter time period (16-17 years). The loan requires a 10% local match, which will be the
responsibility of the BBRSA.
In addition to the revenue generated by stormwater fees within the BBRSA service area boundary, the BBRSA has
also obtained funding from Timnath. The BBRSA entered into an intergovernmental agreement (Boxelder/Timnath
IGA, dated November 15, 2012) with Timnath and its TDA which provides that the TDA shall participate in the funding
of the projects. Pursuant to the Boxelder/Timnath IGA, the TDA has transferred $500,000 to the BBRSA for use in
the design of the remaining projects. In addition, the TDA will reimburse the BBRSA for 25% of the total costs of the
remaining projects. The financial participation by Timnath results in a decrease in the amount of revenue required to
be collected by the BBRSA.
The combination of annual stormwater service fee revenue collected by the BBRSA and the financial contribution from
Timnath provides sufficient funding to cover the on-going costs of the BBRSA and the CWCB loan payment.
ENVIRONMENTAL IMPACTS
The IGA contains language that ensures a holistic approach toward stormwater quality best management practices,
stream stability, and habitat enhancement. Through reconfiguration of the master plan improvements, most notably
increased detention storage at the Gray Lakes Detention Project, the BBRSA is able to eliminate the majority of Middle
Basin improvements proposed in the original Boxelder Regional Stormwater Master Plan. As a result, the need to
grade or alter the majority of Boxelder Creek south of County Road 50 has been eliminated, thereby protecting the
existing stream corridor.
STAFF RECOMMENDATION
Staff recommends adoption of the Resolution.

WHEREAS, the Authority has determined the most cost efficient method of
funding the Projects is obtaining a loan through the Colorado Water Conservation Board
(“CWCB”); and
WHEREAS, the CWCB loan requires a 10% local match resulting in a $9.0
million loan. This match will be the responsibility of the Authority with TDA reimbursing
the Authority 25% of the match pursuant to the Timnath IGA; and
WHEREAS, the Authority has met with the Members and reviewed the design
and construction of the Projects, the funding of the Projects, and the terms and
conditions of the proposed loan from CWCB; and
WHEREAS, the Authority has requested the Members amend the IGA to allow
the Authority to move forward with the funding and construction of the Projects; and
WHEREAS, upon completion of the Projects, payment of all debt incurred by the
Authority for the construction of the Projects, and agreement among the Members as to
any continuing obligation for operation and maintenance of any Authority projects, there
is no longer any need to continue with the Authority; and
WHEREAS, the Authority and the Members have also determined that the
Authority should have the right to make minor revisions to properties within the Service
Area of the Authority by designating areas as “non-tributary areas”, and grant fee credits
to other areas within the Service Area; and
WHEREAS, the Members have determined to enter into this First Amendment in
order to address the funding and construction of the Projects, the granting to the
Authority the right to provide fee credits to appropriate properties within the Service
Area, and the termination of the Authority.
NOW, THEREFORE, in consideration of the mutual covenants contained herein
and other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the Members hereto agree as follows:
1. Article II of the IGA shall be amended by the addition of Section 2.10 to read as
follows:
Section 2.10 Service Area Revisions. The Authority shall have the authority to
make minor revisions to the Service Area by designating properties as “Non-
Tributary Properties” or grant fee credits to other properties within the Service
Area as follows:
3
(a) The Authority may, on a case by case basis, determine that individual
properties in the Service Area are not tributary to the Boxelder Basin; and
based upon that determination, remove those properties from the Service
Area of the Authority. Any such removal shall be communicated to the
Members in order for the individual Member to make appropriate adjustment
in its fee structure.
(b) The Authority may designate areas in the Service Area as “100 percent fee
credit” properties based upon the following criteria:
1. There are properties located within the Service Area which as of the date
of this Amendment drain into Soil Conservation Service/Natural
Resources Conservation Service dam-impounded lakes and decreed
irrigation reservoirs that in 100 year storm event release upstream waters
at a rate less than or equal to the release from an historic two year storm
event. This effectively provides mitigation of downstream flood damage.
These properties are eligible for 100% fee credit on the annual stormwater
service fee as long as these conditions continue.
2. If a residential (dwelling) or commercial structure lies within a sub-basin
area that drains to a lake, pond and/or depressed feature, which does not
contribute runoff to the Boxelder Basin during a 100 year storm, the sub-
basin shall be considered to be a non-tributary sub-basin and the
individual property containing the residence (dwelling) or commercial
structure is eligible for 100% fee credit on the annual stormwater service
fee as long as the conditions do not change. The criteria for the
Authority’s determination of such a sub-basin area being a non-tributary
sub-basin is set forth on Exhibit A attached hereto and incorporated herein
by reference.
(c) If the Service Area boundary intersects any portion of a residential (dwelling)
structure, then the property upon which the residence is located shall be
assessed 50% of the annual stormwater service fee.
(d) All fee credits shall be given on a calendar year basis. The Authority shall
provide each individual Member with the 100% fee credit and 50% assessed
properties located within each Member’s jurisdiction for the purpose of
allowing the Member to calculate credits for any properties entitled to fee
credits.
2. The IGA shall be amended by the addition of the following two Articles:

ARTICLE IX
EAST SIDE DETENTION FACILITY/GRAY LAKES AND LARIMER/WELD
COUNTY CANAL CROSSING STRUCTURE PROJECTS FUNDING.
Section 9.01 The Members hereby agree to authorize the Authority to
apply for and receive a loan from the Colorado Water Conservation Board for the
design and construction of the Projects upon the following terms and conditions:
(a) The amount of the loan from the CWCB shall not exceed the
principal sum of $9 million.
(b) The Authority shall be responsible for the local match which is 10%
of the principal sum of the loan. The 25% TDA reimbursement shall be shall be
part of the local match.
(c) The term of the loan shall not exceed fifteen (15) years.
(d) The interest rate on the loan shall not exceed 2.75% APR.
(e) The Members shall provide any documentation or authority
required by the CWCB of the Members for the Authority to obtain and close this
loan.
ARTICLE X
TERMINATION OF AUTHORITY
Section 10.01 The Members agree that the Authority shall terminate upon
the occurrence of the following events:
(a) Completion of the East Side Detention Facility/ Gray Lakes and
Larimer/Weld County Canal Crossing Structure projects.
(b) Payment in full of the loan from the CWCB and any other
obligations of the Authority.
(c) Agreement among the Members with regard to any continued
obligation of the Authority which extends beyond the termination of the Authority
including, but not limited to, operation and maintenance responsibilities for the
5
Coal Creek Flood Mitigation, the East Side Detention Facility/ Gray Lakes, and
Larimer/Weld County Canal Crossing Structure projects.
(d) Agreement among the Members as to payment of any Authority
obligation to the Members for matching funds of the Members for the FEMA Pre-
Disaster Mitigation Grant in the approximate amount of one million dollars
($1,000,000).
(e) Agreement among the Members as to the disbursement of any
revenues of the Authority which remain after the Authority has finalized all of the
administrative and organizational requirements necessary to terminate the
Authority including, but not limited to, any required budgets, audits, and filings
with any state or federal authority.
Upon the occurrence of all of the above contingencies, the Authority shall
terminate.
3. This Amendment shall be effective upon the execution of the First Amendment by
all of the Members.

EXHIBIT A
Policy for Non-Tributary Sub-Basin:
If a residential (dwelling) or commercial structure lies within a Sub-Basin area that
drains to a lake, pond and/or a depressed feature that can be shown to not contribute
runoff to the Boxelder Basin during a 100-year storm, then the Sub-Basin will be
considered to be a Non-Tributary Sub-Basin and the owner of the residential (dwelling)
or commercial structure will be given a 100% fee credit on the annual stormwater
service fee as long as the conditions don’t change.
Option A: The following method can be used to determine if the Sub-Basin area in
question is a Non-Tributary Sub-Basin:
Step 1: Determine the entire drainage area for the basin, using the best available
topographic data. .
Step 2: Determine the percent impervious area for the entire drainage area based
on best available aerial imagery. Using Table RO-5 in Volume 1 of the Urban
Storm Drainage Criteria Manual determine the associated ‘C’ value for Type C
and D soils (Table attached).
Step 3: Using the Rational Method Formula: Q=ciA Determine the volume of
runoff for the closed basin area assuming a 2-hour design storm with a total depth
of 3.67 inches. Multiply the volume by 2 to account for prior rainfall events.
Step 4: Determine the volume of storage available within the pond, lake or
depressed area being sure to account for the normal water surface elevation if
there is one.
Step 5: Compare the volume of runoff with the volume of storage available. If the
volume of runoff is less than the volume of storage then the basin is a Non-
Tributary Sub-Basin.
Option B: The property owner can hire an engineer to prepare a ModSWMM computer
model of the basin and storage area and prove through modeling that the basin is Non-
Tributary.
The Authority may require a property receiving a fee credit draining to a Non-Tributary
Sub-Basin to provide a legal easement which permanently dedicates the available
storage volume for stormwater management purposes.
