AGENDA ITEM SUMMARY
FORT COLLINS CITY COUNCIL 20
SUBJECT
First Reading of Ordinance No. 125, 2012 Amending Section 26-543 of the City Code to Update the Stormwater
Master Drainage Plans to Include Basin-Specific Water Quality Best Management Practices and Stream Restoration.
EXECUTIVE SUMMARY
The City of Fort Collins’ Stormwater Master Plan has been updated to include stormwater quality and stream
restoration projects, alongside the already identified stormwater flood control projects. The Master Plan update utilizes
results and information obtained from the Stormwater Utility Repurposing program in conjunction with basin and
stream specific recommendations obtained from the following two program efforts:
A. Basin-Specific Stormwater Quality Best Management Practices (BMP) Selected Plans; and,
B. Stream Restoration and Stability Study and Prioritization with the Multi Criteria Decision Analysis
(MCDA) Tool.
The BMP Selected Plans include recommendations for the treatment of stormwater within portions of the City that
developed prior to the adoption of stormwater quality criteria. The majority of the BMP projects include the retrofit of
existing stormwater detention ponds to include water quality treatment facilities. Funding for the construction of the
identified BMP and stream restoration projects will be drawn from existing stormwater fees. This funding request is
included in the current 2013/2014 Budgeting for Outcomes (BFO) process for Environmental Health.
BACKGROUND / DISCUSSION
The City of Fort Collins updated the Stormwater Master Plans and 100-Year event Floodplain Maps for each of the
City’s thirteen (13) drainage basins after the devastating 1997 flood. The Stormwater Drainage Basin Master Plan (a
combination of separately completed master plans for all 13 drainage basins), approved by City Council in June 2004,
describes the flooding history of each basin, identifies potential problem areas and recommends improvements. The
Master Plan:
• Recommends cost-effective projects to remove properties from floodplains, reduce risk and reduce street
flooding;
• Offers guidance for new development in the basins;
• Identifies approaches to enhance riparian habitat along stream corridors and improve water quality; and,
• Offers broad guidance to stabilize streams where necessary.
In 2008, Council directed staff to review the purpose and components of the City’s Stormwater Program. Staff
organized the Stormwater Utility Repurposing program review into 14 major components as outlined below:
A. Stormwater Purpose Statement
B. Best Management Practices (BMP) Policy Update
C. Stormwater Criteria Update
D. Detention Pond Construction / Landscape Guidelines
E. Stormwater Quality GIS Coverage
F. Low Impact Development (LID) Demonstration Projects
G. LID Policy Review
H. Stormwater Quality Sampling Review
I. City-Owned BMP Review
J. Home Owners Association (HOA) Assistance Program
K. Level of Protection Policy
L. Rates
M. Floodplain Regulations
N. Urban Stream Health Assessment
November 6, 2012 -2- ITEM 20
Information and results from these major components were utilized to update the Stormwater Master Plans to address
storm water quality considerations and to include stream restoration and stability projects that will protect the City’s
urban watersheds, and preserve the natural and beneficial functions of floodplains. The purpose of the Master Plan
Update is not to re-evaluate the previously-identified flood control capital improvement projects; but, to identify areas
where storm water quality and stream improvements are necessary and identify where they may be incorporated into
existing or future flood-control projects.
Studies and Results
1. Basin-Specific Stormwater Quality BMP Selected Plans
In 2011, the Utilities Stormwater Division contracted with three local engineering consultants to prepare basin-specific
water quality Best Management Practices (BMP) selected plans for ten of the City’s master drainage basins:
Spring Creek Dry Creek Fox Meadows
Old Town Mail Creek Canal Importation
Fossil Creek West Vine Foothills
McClelland’s Creek
Boxelder Creek and Cooper Slough were preliminarily evaluated, then removed from further analysis since the majority
of these basins are currently undeveloped; they exceed the goal of at least 40% of undeveloped/BMP coverage land.
Future development within the two basins will be required to install water quality BMP facilities in accordance with City
stormwater criteria. The 40% coverage goal was obtained from the Urban Stream Health Assessment study,
performed by CSU in 2010. In all basins, the stormwater quality BMPs were analyzed and sited to meet or exceed
the recommended 40% coverage goal.
In order to complete the basin-specific BMP selected plans, the following work was performed:
• Hydrologic model updates (to include significant urban development since 2002)
• Hydrologic sensitivity analyses
• Conceptual water quality BMPs
• Alternative analysis of BMPs
• Triple Bottom Line (TBL) analysis of the BMP alternatives
• Draft Selected Plans
• Public outreach process
• Stream Restoration MCDA Prioritization
• Final Selected Plan.
Exhibits of the proposed stormwater quality BMP improvements for each of the ten drainage basins are included as
Attachment 1. A map for the Boxelder Creek/Cooper Slough basin is also included to display the proposed stream
restoration reaches within the basin.
The majority of the BMP improvements consist of retrofitting existing stormwater detention ponds to include water
quality treatment. Other BMPs include in-pipe mechanical BMPs, and irrigation ditch relocations. Typical pond retrofits
include adding new water quality outlets to existing ponds; excavating the sides of existing ponds to achieve additional
water quality volume; moving, replanting, or planting new trees; along with close coordination with neighboring
properties.
2. Stream Restoration/Stability Study and Prioritization of Stream Restoration Projects
In 2011, a study conducted by Colorado State University, on behalf of the Fort Collins Stormwater Division, was
authorized to help prioritize future stream management and rehabilitation work within the City. Assessments (including
field work) were completed between June and October of 2011. The study built upon work completed previously in
the Urban Stream Health Assessment Study and specifically investigated the following ten stream sections within the
city limits of Fort Collins:
November 6, 2012 -3- ITEM 20
Burns Tributary Clearview Channel Foothills Creek
Fossil Creek Langs Gulch Mail Creek
McClellands Creek Spring Creek Stanton Creek
Boxelder Creek (downstream of Vine Drive)
The study provided detailed habitat, susceptibility, and baseline geomorphic data for roughly 17 miles of channels
across ten streams. The objectives of the study were to:
• Perform a geomorphic assessment on a segment-by-segment basis of the ten streams listed above to
determine channel evolution stage, channel susceptibility to vertical and lateral erosion, and stream habitat
condition;
• Use the resulting data to identify geomorphic thresholds that sustain meandering channels and other
heterogeneous physical habitats and use this information to assess candidate restoration reaches; and,
• Identify and prioritize future stream management and rehabilitation work through the development of a Multi-
Criterion Decision Analysis (MCDA) matrix that can be used to select projects that simultaneously improve
habitat, reduce susceptibility, and provide the geomorphic conditions that sustain diverse and stable channels.
- Issues identified within the study include obstacles to fish passage caused by irrigation diversion
structures, dams, and rock grade control structures, which are usually in place to protect existing
infrastructure. Other identified issues include severe bank erosion which contributes to poor water quality,
unsafe areas for the public, threats to infrastructure such as sewer lines, and the loss of property to the
stream. Irrigation flows conveyed through the many of the City’s streams contribute to the bank erosion
through sustained, unvarying flows. These irrigation flows also affect the frequency of flows in the streams,
negatively affecting aquatic and riparian habitats.
2a. Multi Criteria Decision Analysis (MCDA) Tool Prioritization of Stream Restoration Projects and
associated BMP Installations
A MCDA framework for prioritizing stream rehabilitation projects was completed to target areas where the greatest
opportunities exist for simultaneously improving habitat and connectivity while stabilizing high-risk, erosion-susceptible
reaches. The four major criteria for MCDA scoring were:
• Environmental Benefit
• Economics
• Social Value
• Erosion Potential
Based upon Triple Bottom Line (TBL) principles, all criteria were given equal weight within the MCDA tool.
The MCDA sub-criteria, weights, and reach scores were developed by a multi-discipline team consisting of staff from
several City Departments including Utilities, Natural Areas, Environmental Sustainability, and Environmental Planning.
A member of the public, representing the Natural Resources Advisory Board also participated in the MCDA tool
completion process.
The completed MCDA Tool is included as Attachment 2 to this AIS. The stream prioritization results also include the
tributary stormwater BMPs that link to the appropriate downstream stream restoration reach.
The goal of the stream restoration projects is to restore the City’s streams to a natural state, or as natural state as
possible, given the constraints of the urban setting in which they occur. The restoration will be achieved by stopping
and repairing stream bank erosion, removing obstacles to fish passage such as grade controls, ensuring good
stormwater quality, re-vegetating stream banks, and promoting good stream and watershed management practices.
Future stream restoration and stormwater quality BMPs will be implemented according to the project ranking within
the finalized MCDA Tool. Projects will be analyzed and designed using the same multi-disciplinary approach utilized
in the completion of the MCDA Tool, with input from affected property owners being a crucial part of the design,
construction, and maintenance of several of the stream restoration and BMP projects.
November 6, 2012 -4- ITEM 20
FINANCIAL / ECONOMIC IMPACTS
Based upon input from Council at the April 24, 2012 Work Session, a percentage of current stormwater fees will be
used to fund the completion of the identified stormwater quality BMP and stream restoration projects. Beginning in
2013, Stormwater Capital Improvement Project (CIP) funding will be allocated into separate sub-categories in
accordance with the following percentages (dollar amounts to be rounded):
• 16% Stream restoration and stormwater quality BMPs
• 20% Opportunity fund to address unforeseen projects such as development related storm sewers, or cash
matches with government entities (i.e. West Vine Basin Stormwater Improvements with Larimer
County)
• 64% Flood control capital improvement projects (previously 100% of funds)
Accordingly, to achieve the goals of the Stormwater Master Plan, Fort Collins Utilities has submitted a $650,000 per
year Budgeting for Outcomes (BFO) offer for stream restoration/stormwater quality in the 2013/2014 budget process.
It should be noted that there is no proposed increase in stormwater fees to construct these additional projects. Staff
will continue to investigate additional funding sources such as the utilization of the Natural Resources Department
Stream Rehabilitation Funds identified in the 2010 Keep Fort Collins Great Sales Tax package ($250,000 per year);
applying for various grant programs such as the Colorado Healthy Rivers Grant Fund, or the EPA Small Watershed
Grant Program.
Estimated ranges of project costs* for stream restoration and stormwater quality BMPs in the City’s streams and
basins are as follows:
Boxelder Creek (Stream only) $1,117,800 to $2,353,500
Canal Importation Basin (Stream and BMP) $1,586,000 to $1,816,000
Dry Creek Basin (Stream and BMP) $2,976,900 to $5,111,900
Foothills Creek Basin (Stream and BMP) $2,922,000 to $3,777,000
Fossil Creek Basin (Stream and BMP) $20,605,800 to $26,153,500
Fox Meadows Basin (BMP only) $808,200
Mail Creek (Stream and BMP) $4,837,200
McClellands Creek Basin (Stream and BMP) $5,380,400 to $9,679,900
Old Town Basin (BMP only) $1,539,100
Spring Creek Basin (Stream and BMP) $7,648,700 to $10,157,600
West Vine Basin (Stream and BMP) $2,835,300 to $4,144,700
Total costs range from: $52,257,400 to $70,378,500
* Upper cost ranges are based upon a per linear foot construction cost. Cost ranges are presented due to the fact that
not all stream restoration work requires capital construction. Several stream reaches may be rehabilitated through
minor construction and watershed/vegetation management.
ENVIRONMENTAL IMPACTS
The health of the City’s physical environment will be positively affected as a result of the Master Plan Update. Water
quality throughout the City will be greatly improved, while several of the eroding banks within the City’s waterways will
be repaired and stabilized. Wildlife habitat will be improved and new riparian habitat will be planted along the streams.
Impediments to the passage of fish throughout the streams will be removed, allowing for a greater number and
diversity of aquatic species along the streams. Excessive sediment and pollutants will be removed from the streams
as a result of the installation of new stormwater quality BMPs in basins that currently have no stormwater quality
treatment. The projects in the Plan will also serve to protect existing infrastructures such as sanitary sewers,
preventing potential sewage spills in the City’s natural streams.
STAFF RECOMMENDATION
Staff recommends adoption of the Ordinance on First Reading.
November 6, 2012 -5- ITEM 20
BOARD / COMMISSION RECOMMENDATION
The Master Plan Update was presented to boards and City Council on previous occasions. They include:
1. Water Board – January 19, 2012
2. Natural Resources Advisory Board (NRAB) - February 22, 2012
3. Water Board – April 19, 2012
4. City Council Work Session – April 24, 2012
5. NRAB – September 19, 2012
6. Water Board – September 20, 2012
The Stormwater Master Plan Update was presented to both the NRAB and the Water Board on September 19 and
September 20, 2012, respectively. The Plan Update was unanimously recommended for adoption by both Boards.
Draft minutes from both meetings are included as Attachments 3 and 4.
PUBLIC OUTREACH
The public outreach process for the Stormwater Master Plan Update has been ongoing since June 2011, and has
included the following elements:
• Basin-specific focus group meetings for affected stakeholders such as CSU, Poudre School District, home
owners associations (HOA), various City departments, and the Downtown Development Authority.
• Website explaining the Master Plan Update – fcgov.com/stormwater-plan - 170 unique hits as of September
25.
• Article in the City News flyer – included in Utility Bills to all Utilities customers directing customers to the
Master Plan website
• Booth at the New West Fest – direct contact with over 250 people, with several thousand people stopping to
look at the booth signage
• Online survey of 674 citizens about general stormwater issues within the City, including water quality and
stream restoration
• Facebook update directing City followers to the Master Plan website
• Twitter update directing City followers to the Master Plan website
The conceptual BMP alternatives were presented for initial public review and input through a series of Focus Group
meetings in summer 2011. Representatives from City departments, homeowners associations, management
companies for existing BMP facilities, large businesses and institutions (i.e., Colorado State University), and interested
citizen groups (i.e., Save the Poudre).
The future public outreach process for the individual stormwater quality and stream restoration projects identified in
the Master Plan Update will include the following elements;
• Project-specific meetings and/or Open Houses for affected stakeholders such as HOAs, individual property
owners, City departments, and interested organizations
• Website explaining the individual project, the project schedule, and ways for the public to provide feedback
and comments
• Mailers to potentially affected stakeholders informing them of Open House times and topics
• Ongoing social media updates
The projects will be presented and discussed with all affected parties through a collaborative outreach process where
all participants will be allowed the opportunity to provide meaningful feedback and potentially affect the final design
of the project. A Public Engagement Plan, which details the current and ongoing outreach process for the update and
for future projects, is included as Attachment 5. The Public Engagement Plan was submitted to City Council for review
in June 2012.
In an online Stormwater survey conducted by Fort Collins Utilities in August 2012, over 90% of the 674 respondents
indicated that protecting and improving water quality is important to them. The reduction of pollutants in stormwater
runoff was ranked second in importance only second to maintaining existing stormwater infrastructure. 75% of
November 6, 2012 -6- ITEM 20
respondents also felt that the City’s streams have become more polluted over the last 20 years. Fort Collins Utilities
will use the results of the survey to guide and inform our future public outreach efforts regarding the specific projects
identified within the Master Plan Update.

Stormwater Master Plan Update
(Attachments available upon request).
Stormwater and Floodplain Manager Ken Sampley introduced the item and introduced
Stormwater Master Planning Manager Mark Kempton.
Mr. Kempton began the presentation by discussing the key results that will be achieved by
updating the Master Plan. These include integrating flood control and water quality projects into
one comprehensive plan, a prioritized listing of stream rehabilitation projects, and a prioritized
listing of retrofitted stormwater Best Management Practice (BMP) projects.
The Master Plan was originally presented to the Water Board in January, and again in April. It
was presented at a City Council Work Session in April. Staff has also presented it to the Natural
Resources Advisory Board (NRAB).
The Master Plan Updates will be finalized using data, information, and results from two separate
program efforts: Basin-Specific BMP Selected Plans and the Stream Restoration and Stability
Study.
Mr. Kempton showed a map outlining the Basin-Specific BMP Selected Plan for different areas
of the City. He also presented a map showing the proposed Canal Importation (CI) Basin
Management for the Village West Pond. The proposed BMPs include excavating the pond and
providing a new water quality outlet, maintaining the existing pond invert, and moving and/or
replanting trees. This requires close interaction with affected neighbors.
A board member expressed concern about potential flooding in the area as it relates to the
Horsetooth Dams. Mr. Kempton stated the ponds would be inundated and have no flood
attenuation effects in the unlikely event of a Horsetooth dam break. He also stated it is not staff’s
intent to remove all existing trees and vegetation for existing pond areas, but to work closely
with adjacent property owners to save and/or relocate as many trees as possible within the pond
footprint.
Mr. Kempton presented the goal for the Stream Restoration and Stability Study:
Prioritize future stream management and rehabilitation work on 10 streams within the
City of Fort Collins in coordination with the Basin-Specific BMP Selected Plans.
Mr. Kempton identified some problems that resulted from the study, including obstacles to fish
passage and erosion problems. Erosion problems are present with Clearview Channel, Fossil
Creek near Lemay Avenue, Spring Creek, and Stanton Creek. Irrigation flows are transported
through several of the City’s natural streams. These drastically alter the natural flow regime –
high, sustained flows cause erosion. Diversion structures and dams impede fish passage and
habitat connectivity.
Mr. Kempton presented information on the Multi-Criterion Decision Analysis (MCDA) Tool.
This is used to assess and prioritize stream rehabilitation and associated BMP projects. This
provides a meaningful way to prioritize projects, and rates the importance of environment, social,
and economic benefits to the project. The MCDA Working Group consisted of Utilities, Natural
Resources, Sustainability, Planning, and a member of the Natural Resources Advisory Board.

Page 2 of 3
Completion of the MCDA Tool included videos of each stream reach linked in Google Earth and
a three hour field visit to representative reaches. 12 people evaluated 17 miles of stream in three
separate meetings.
The top four results from the MCDA Tool include:
Fossil Creek west of Lemay Avenue
Mail Creek by Werner Elementary School
Spring Creek just east of Riverside Avenue
Mail Creek near Fossil Creek
Mr. Kempton presented before and after pictures from the stream restoration project on
McClellands Creek during April and August 2012.
Mr. Kempton presented information on the Public Outreach Process. This included a booth at
New West Fest, Facebook and Twitter updates, a website (www.fcgov.com/stormwater-plan),
and Utility bill mailers.
Mr. Kempton outlined the Funding Considerations for the project. These include Flood Control
Projects currently identified and funded using existing stormwater fees. Currently there is no
dedicated stormwater funding source for Stream Rehabilitation/BMP projects.
Mr. Kempton presented the Project Schedule:
July – September 2012 (Public Outreach)
August 2012 (Complete stream rehabilitation prioritization using the MCDA tool)
September 2012 (Present results to NRAB and Water Board)
November 2012 (Present results to City Council)
2013/2014 (Implement stream restoration and/or BMP projects)
Next steps in the process include developing a new Stream Restoration Program. This includes
Public Outreach, Irrigation Flow Management, Design, Capital Projects, Monitoring,
Maintenance, and Planning and Zoning. The new program also includes vegetation management
and riparian buffer standards.
Staff recommends approval of the Stormwater Master Plan Update.
Highlights from the discussion:
A board member expressed appreciation for staff’s efforts on the project. The board
member is impressed with the work completed thus far.
A board member expressed concern about the amount identified for restoration and
BMPs. The board member questioned if other departments will share in the maintenance
costs. Mr. Haukaas stated staff will leverage funds where they can, such as partnering
with Natural Areas or Homeowner Associations. Grant funding is also a possibility. The
estimated numbers are based on today’s priorities and needs. More specific project details
will come later and will be adjusted after bonds are paid and debt is reduced.
A board member questioned the cost for a rehabilitated stream reach. Mr. Kempton stated
this depends on the design.

PROJECT TITLE: STORMWATER MASTER PLAN UPDATE – STREAM RESTORATION AND STORMWATER
QUALITY IMPROVEMENTS
PROJECT LEAD: UTILITIES ‐ STORMWATER MASTER PLANNING
OVERALL PUBLIC INVOLVEMENT LEVEL: Variable depending on Phase
BOTTOM LINE QUESTION: Does the public and directly affected parties agree with the stream restoration
and stormwater quality goals and methods outlined in the master plan update?
KEY STAKEHOLDERS: Fort Collins residents, HOAs, Poudre School District, CSU, Larimer County, various City
of Fort Collins Departments, irrigation ditch companies, and private landowners.

damage to public and private property, erosion and impacts on waterways and natural
areas, pollution of creeks and the Poudre River;
o Original Stormwater Master Plans (circa 2003) focused primarily on flood control projects
that addressed life‐safety and reduced property damage;
o Increased emphasis in last 10 years (including Federal Mandates) on quality of stormwater
runoff and its impact on rivers, creeks, water supply, etc. and why it is important to have
healthy streams;
o Key Updated master plan elements include;
Maintain original listing of flood control projects
Identified stream reaches that need to be restored
Identified locations where BMPs are needed to improve stormwater quality (i.e.
existing stormwater detention pond areas to be retrofitted to capture pollutants and
provide water quality treatment)
No increase in stormwater fees proposed
Developed proposed multi‐pronged funding approach for CIP portion of
stormwater fees
20% of CIP funds for opportunity projects
64% of CIP funds for flood control projects (and associated BMP retrofits)
16% of CIP funds for restoration of stream reaches (and associated BMP
retrofits)
o Restore streams to provide quality wildlife habitat and stable stream banks
o Address irrigation ditch flows in the streams that cause bank erosion and degrade wildlife
habitat
o Address public safety issues such as high, steep banks and eroding culverts or bridges.
