SUBJECT
Public Hearing and First Reading of Ordinance No. 159, 2018, Amending Chapter 26 of the Code of the City of
Fort Collins to Adopt a New Fort Collins Stormwater Criteria Manual and Making Various Related Changes.
EXECUTIVE SUMMARY
The purpose of this item is for City Council to adopt the updated Fort Collins Stormwater Criteria Manual (Manual)
into City Code, and to make related changes to City Code updating references to the Manual. The Manual sets
forth design guidelines and technical criteria that are utilized in the analysis and design of stormwater drainage
systems. The Manual serves as the governing criteria for all stormwater improvements, public or private, that
are designed and installed within Fort Collins and its Growth Management Area (GMA). In short, the Manual is
the primary reference document for engineering consultants when preparing stormwater system designs, and
for Fort Collins Utilities staff to confirm stormwater system designs are in compliance with regulations and
associated requirements.
The Manual is being updated to replace, in its entirety, the previously adopted “Fort Collins Amendments to the
Urban Drainage and Flood Control District Criteria Manual” dated December 2011. The objective is to create a
single, stand-alone document that incorporates all key design guidance and more effectively communicates the
criteria for Fort Collins and its Growth Management Area (GMA). The Manual is consistent with the recent City-
wide development review process updates and will be more user-friendly and easier for users to navigate,
interpret and apply. While the criteria presented in the updated Manual are consistent with the currently adopted
Manual, there are some proposed technical updates and policy changes included.
STAFF RECOMMENDATION
Staff recommends adoption of the Ordinance on First Reading.
BACKGROUND / DISCUSSION
History and Origins of Fort Collins Stormwater Criteria Manual
The first stormwater reference manual for the City of Fort Collins was developed in the early 1980s, with formal
adoption in May 1984. Subsequent updates to the original manual were adopted in March 1991 and in January
1997. The updates incorporated portions of the Urban Drainage and Flood Control District (UDFCD) Manual,
and more specifically, the Volume 3 (Water Quality) requirements. The UDFCD was established by the Colorado
legislature in 1969 for the purpose of assisting local governments in the Denver metropolitan area with multi-
jurisdictional drainage and flood control problems. UDFCD promulgates criteria and publishes their own criteria

manual, for adoption by communities within the region. The UDFCD Criteria Manual is a “best practices”
document that is widely recognized both regionally and throughout the United States for its excellence.
In July 1997, Fort Collins experienced the Spring Creek flood. Following this devastating event, the City
completed a study to re-evaluate the amount of rainfall associated with the 100-year frequency storm. In March
1999, City Council adopted the new rainfall standards to be used in the design of stormwater facilities. The prior
criteria of 2.89 inches for the 100-year, two-hour storm was revised to 3.67 inches.
UDFCD Influences on the Manual
With the basis of the Fort Collins storm drainage criteria becoming more and more influenced and based on
UDFCD standards, it was determined in late 2008 that the Manual should be updated once again, but this time,
the UDFCD Manual was adopted in its entirety, along with amendments and exceptions that were specific to
Fort Collins.
The resulting Manual, which was adopted by Council in December 2011, is referred to as the Fort Collins
Amendments to the UDFCD Manual. The “amendments” format resulted in a document that included text where
Fort Collins regulations amended or differed from those of the 2001 version of the UDFCD manual. The end-
users of this document were required to refer to both the “amendments” manual and the 2001 UDFCD manual
simultaneously for a complete understanding of the criteria. Staff has received feedback from the development
community and consulting engineers that the format of the “amendments” manual is difficult and cumbersome
to follow and can create confusion in the application of criteria. In addition, the UDFCD updated and completely
reformatted its manual in 2016 rendering the “amendments” references outdated.
Proposed “Stand-Alone” Format of the Updated Manual
The updated Manual replaces in its entirety the previously adopted “Fort Collins Amendments to the Urban
Drainage and Flood Control District Criteria Manual” dated December 2011. The updated manual also changes
from a format of making “amendments” to the UDFCD Manual to a stand-alone document that incorporates all
key design guidance and more effectively communicates the criteria for Fort Collins and its GMA. The document
will be more user friendly and easier for users to navigate, interpret and apply. While the criteria presented in
the updated Manual are consistent with the currently adopted Manual, there are some proposed technical
updates and policy changes included.
Updated Manual Chapter Highlights
Information incorporated into the various chapters includes, but is not limited to, the following main topics:
• Chapter 1: Drainage Principles and Policies.
This Chapter includes an overview of the City of Fort Collins guiding principles on the control and treatment
of stormwater; including discussion on how the principles are made operational through a set of policies.
• Chapter 2: Development Submittal Requirements.
This Chapter outlines all submittal requirements for drainage and erosion control for each step of the
development review process. In addition, this Chapter outlines a variance request process for designs that
do not conform to the criteria. This Chapter is an enhancement to the previous manual because it provides
more specific step-by-step details and checklists for each step of entitlement and is consistent with the recent
Citywide development review process updates.
• Chapter 3: During and Post-Construction Requirements.
This Chapter outlines standard procedures during the construction phase for: erosion control measure
installations, inspections and ongoing maintenance, and drainage certification requirements at or near the
end of construction that enables the development team to receive building permits and/or certificates of
occupancy (CO).

Agenda Item 13
Item # 13 Page 3
• Chapter 4: Construction Control Measures.
This Chapter provides information on the City’s erosion and sediment control program criteria.
• Chapter 5: Hydrology Standards.
This Chapter provides rainfall data, design storm standards and methodologies in which to compute
stormwater runoff; including further defined technical requirements on hydrology calculations and hydraulic
analyses.
• Chapter 6: Detention.
This Chapter provides the design requirements for traditional detention basin design as well as alternative
detention facilities such as underground detention options.
• Chapter 7: Water Quality.
This Chapter includes design guidance in selecting, maintaining and implementing permanent best
management practices (BMPs) for development sites that minimize water quality impacts from stormwater
runoff. This Chapter further defines the similarities and differences between standard BMPs and Low Impact
Development (LID) water quality control practices. LID practices include more filtration of storm runoff to
achieve higher reduction of pollutants. This Chapter discusses the LID ordinance requirements and provides
design guidance for LID systems.
• Chapter 8: Grading.
This Chapter provides requirements and guidance on site grading parameters to be incorporated into overall
site design and for more specific locations such as single-family lots and detention basins. In addition, this
Chapter provides more specific guidance on drainage easement requirements.
• Chapter 9: Streets, Inlets and Conveyance.
This Chapter provides design guidance for stormwater collection and conveyance systems, utilizing streets,
inlets, storm drains and other types of conveyances such as open channels.
• Appendix A: Development Review Checklists.
To be utilized by design engineers that are preparing drainage reports and construction plans for
development projects.
• Appendix B: Landscape Design Standards and Guidelines for Stormwater and Detention Facilities, 2009.
This document provides guidance for creating detention basin areas that look and feel like natural areas that
may support habitat, serve as buffer zones and that can be multi-purpose spaces.
• Appendix C: LID Implementation Manual.
The LID Manual illustrates various LID concepts suitable for different land use types and drainage conditions
and provides general guidance for the successful implementation of LID in order to comply with, or exceed,
current City LID criteria. The LID Manual is a significant addition to the updated Manual.

Agenda Item 13
Item # 13 Page 4
• Appendices D, E, F: Construction Control Measures Guidance, Fact Sheets and Standard Notes.
These appendices focus on the practical application of the erosion control requirements by providing
document preparation guidance and field implementation examples.
The updated Manual continues to utilize much of the information included in the UDFCD Manuals, old and new,
and acknowledges UDFCD for its role in advancing the practice of science, engineering and management of
watersheds and streams through research, innovation and education. However, there are some criteria in the
UDFCD Manual that are not applicable in Fort Collins and its GMA and do not meet the requirements set forth
in the updated Manual. In addition, there are certain requirements that Fort Collins continues to regulate that are
set forth in the updated Manual but are no longer fully addressed in the current UDFCD Manual.
LID Technologies and Techniques in the Updated Manual
Low Impact Development (LID) refers to systems and practices that use or mimic natural processes to infiltrate,
evaporate, reduce stormwater runoff and reduce potential release of pollutants in order to protect water quality.
With the adoption of the City of Fort Collins’ LID ordinance in February 2013 (Ordinance No. 152,2012), it
became increasingly necessary to establish design parameters and construction details for the various LID
systems so that the end product is a functional system that meets the intent of the ordinance. In late 2015, a
“LID and Permeable Pavers Roundtable” committee was established to review the application of the LID criteria
and to respond to inquiries from the development and consulting engineering community. As a result of this
committee, the code language for the LID policy was revised in 2016. (Ordinance No. 007, 2016) Since the LID
policy was established subsequent to the current “amendments” manual, the manual did not provide information
explaining how the LID criteria should be implemented. The committee therefore recommended the creation of
an LID Implementation Manual (LID Manual) to provide examples showing how the criteria should be applied to
typical development projects.
The purpose of the LID Manual is to act as a tool for development design teams to better understand and meet
City LID requirements for development projects. The LID Manual illustrates various LID concepts suitable for
different land use types and drainage conditions and provides general guidance for the successful
implementation of LID in order to comply with, or exceed, current City LID criteria. Additionally the LID Manual
offers guidance on the maintenance of various types of LID facilities and provides the City with a consistent set
of digital construction details that standardize the construction of LID measures on public and private property.
It is designed as a living document that can be easily adapted and updated as new LID technologies are adopted
by the industry and by FCU. The Low Impact Development (LID) Manual is included as Appendix C in the
updated Manual.
Scheduled Manual Updates
It is the intent of the FCU Stormwater staff to provide updates to the Manual on a bi-annual basis, if needed. The
contents of the Manual will be reviewed for any needed technical or industry standard updates. Technical
corrections or updates will be processed through the Utilities Executive Director. Any policy updates or changes
would be brought to City Council for approval.
CITY FINANCIAL IMPACTS
The updated Manual was developed internally using existing Fort Collins Utilities Stormwater staff. The LID
Implementation Manual was created with the assistance of a consultant at a cost of $55,000. A separate
consultant was hired at a cost of $3,000 to review the erosion control content of the Manual to ensure consistency
and alignment with the City’s MS4 permit requirements.
Staff does not anticipate additional design costs as a result of the Manual and believes that there will be cost
savings due to a more streamlined process and Manual. Construction costs associated with individual lot erosion
control are estimated to average $2000 per lot. This may be considered a cost implication due to the proposed
codification of the single lot protection requirement with the Manual. City staff assembled a detailed document

responding to the costs of installing and maintaining erosion control. This document is included as Attachment
3.
BOARD / COMMISSION RECOMMENDATION
The LID Implementation Manual (Appendix C of the updated Manual) was presented to the Land Conservation
Stewardship Board on July 12, 2017. The LID Implementation Manual was unanimously endorsed by that board
following the presentation.
The updated Manual project was presented to the Water Board on two different occasions. The first, on
September 21, 2017, which provided an overall review of the Manual and the updating process. In 2017, the
Water Board recommended unanimously that City Council adopt the updated Manual. The second presentation
to Water Board occurred on October 18, 2018 to further detail outreach efforts and subsequent technical and
policy revisions related to the erosion control criteria of the Manual. In 2018, the Water Board again
recommended unanimously that City Council adopt the updated Manual.
The updated Manual project was presented to the Chamber of Commerce on two different occasions. The first,
on November 3, 2017, and the second in June 22, 2018. Like the process for the Water Board, the first
presentation to the Chamber included a broader overview of the updated Manual, and the second presentation
was focused on the erosion control criteria.
Most recently, the Manual was presented to the Planning and Zoning Board Work Session on September 14,
2018 and the Development Review Advisory Committee on November 13, 2018.
PUBLIC OUTREACH
An extensive public outreach effort was conducted for this project starting in May 2017 and finishing recently
with a presentation to the Development Review Advisory Committee on November 13, 2018. The initial outreach
efforts for the updated Manual consisted of emailing over 160 contacts that have worked with FCU staff in recent
years. The contacts included people from local development firms, consulting engineers, land planners and
contractors that provide all variations of construction work including erosion control, utility installation, structural
work, building contractors and landscaping companies. The updated Manual was also reviewed by several City
departments including: Engineering Development Review, Environmental Regulatory Group, Planning and the
City Attorney’s Office.
A 70% draft of the Manual was distributed to the stakeholder group on May 23, 2017. Comments and input on
this draft were requested to be provided by June 16, 2017. Of the 34 consulting engineering firms contacted, 11
different firms responded. Many of the comments provided were based on grammatical errors and requested
formatting changes and were not substantive in nature.
Important highlights from the responses and feedback included:
• further clarification on technical requirements for hydrology and hydraulic analyses;
• erosion control documentation and construction site requirements;
• variance process updates;
• further clarification on LID system design parameters; and,
• clarification on required easements
A 90% draft of the Manual was distributed again to the same stakeholder group on July 28, 2017 with comments
requested by August 14, 2017. All comments have been reviewed, taken under consideration and incorporated
where appropriate.
As noted previously, the LID Implementation Manual was created as a result of the outreach. This went through
a separate public outreach process that included the formation of an LID Roundtable consisting of staff and
representatives from the public who discussed ways to ease the implementation of the current LID criteria and
COPY

policies. This effort led to the creation of the LID stakeholder team, consisting of City staff, local design
professionals, public individuals interested in the subject and two City Councilmembers (Councilmember Ross
Cuniff and former Councilmember Gino Campana). This group was instrumental in brainstorming with staff about
what issues needed to be addressed by the LID Implementation Manual and offered valuable feedback to staff
by reviewing a draft of the manual. A steering committee was formed, which consisted of City staff from multiple
departments, to develop the final LID Implementation Manual. The City departments represented in the steering
committee included personnel from Utilities, Planning and Development, Engineering and Forestry.
While significant stakeholder outreach was conducted in late 2017, staff determined that additional engagement
was needed on the erosion control requirements stated in the Manual. Key outreach events included a
Developer’s Breakfast meeting on June 21, 2018 and a presentation to the Chamber of Commerce on June 22,
2018.
Both events were well attended, and a great deal of feedback was received. Staff organized the feedback into 6
primary categories – (1) vegetation density, (2) signatory requirements, (3) plans and reports, (4) escrows, (5)
individual lot protection and treatment train approach and (6) cost. City staff assembled a detailed document
responding to these focus areas. The full document is included as Attachment 3. A summary is provided herein.
1. Vegetation Density
a. Summary of Input: Several external stakeholders noted that achieving 70% vegetative cover on
sites in Fort Collins is an impractical and difficult standard to achieve, especially with native
seed. This requirement has been in City code since the early 90s, when the more typical
vegetation coverage was irrigated turf. As the City now encourages a greater use of native
seed, this standard has been very difficult to achieve and may take years to reach compliance
which results in the City holding erosion control escrow for several years.
b. City Response: The updated Manual is not proposing any changes to the current standard.
However, the City is committed to addressing this concern:
i. A City of Fort Collins internal Revegetation Team has been assembled and will meet in
January of 2019 to reevaluate this standard, particularly with a focus on the requirement
for establishment of native species versus turf.
ii. In the first half of 2019, the Revegetation Team will develop a list of potential options to
consider.
iii. In summer of 2019, we will engage community stakeholders in a facilitated workshop to
ensure we have identified common concerns, captured the varied perspectives and
goals around erosion and sediment control and water quality management, and discuss
the possible options. Stakeholder participants may include developers, design
engineers, home builders, erosion and sediment control practitioners, environmental
protection and conservation groups, members, citizens and relevant City departments.
2. Signatory Requirements
a. Summary of Input: Stakeholders commented that proposed language outlining roles and
responsibilities of the developers, owners and contractors, and including a requirement for
signatures of all responsible parties on the erosion control report creates confusion in contract
language between developers and their contractors and creates another step in the process
with limited or no foreseeable benefit.
b. City Response: Staff has removed this proposed change from the Manual.
3. Plans and Reports
a. Summary of Input: Stakeholders commented that the Professional Engineer (P.E.) requirement
for submission of erosion control materials is not appropriate, is unnecessary, and that other
jurisdictions do not require erosion control plans and reports to be prepared by a P.E
b. City Response: City staff is committed to working on a resolution for this concern and staff will
engage in data collection and benchmarking effort in 2019 to identify best practices by other
municipalities along the Front Range. Any future proposed changes to this standard will include
stakeholder input and feedback in 2019.
4. Escrows
a. Summary of Input: Stakeholders commented that the City does not have a clear and equitable
process for transferring responsibility of erosion escrows.
COPY
Agenda Item 13
Item # 13 Page 7
b. City Response: The updated Manual provides a process for re-calculation and reduction of
erosion control escrows based on phasing of the construction and stabilization of the site. We
heard from stakeholders that this is a welcomed improvement, but that more work is needed
overall with the city-wide escrow process. In 2019, staff will convene a team of Utilities and
Planning, Development, and Transportation (PDT) staff to look at ways to improve this process
that bridges across several city departments. The timeline and tasks associated with global
changes to the City’s escrow process are not clear at this point, but our commitment is to provide
an update to stakeholders later in 2019.
5. Individual Lot and Treatment Train Requirements
a. Summary of Input: Stakeholders commented that requiring individual lot protection, in addition
to downstream sediment and erosion controls, is redundant and excessive and creates undue
maintenance and cost implications.
b. City Response: Currently, City staff recommends including this requirement in the updated
Manual. Without individual lot protection we have:
i. Increased sediment tracking onto public streets, which ends up in the storm sewer
system
ii. A higher volume / load of sediment and associated pollutants being directed and
deposited into end treatments (i.e. water quality ponds) resulting in higher and more
frequent maintenance.
iii. Challenges with ensuring frequent maintenance is performed on end treatments,
tracking the appropriate responsible parties, and not impacting already fully constructed
and established end-treatments
iv. Introducing a higher level of associated pollutants (i.e. hydrocarbons, nutrients) into the
treatment process which reduces its efficiency.
c. The updated Manual does provide a variance to allow an engineer to design for “equal or better”
treatment. City staff will continue to explore other technologies and applications for controlling
sediment at its source and remains open to further discussion with the development/home
builder stakeholders.
