SUBJECT
ADDITIONS AND SUBSTANTIAL IMPROVEMENT CODE CHANGE FOR FEMA FLOODPLAINS
EXECUTIVE SUMMARY
Fort Collins Utilities is conducting outreach related to a proposed regulatory change to Chapter 10 of
City Code to come into compliance with minimum regulations from the Federal Emergency
Management Agency (FEMA) regarding additions and substantial improvements in FEMA floodplains.
BACKGROUND
The Federal Emergency Management Agency (FEMA) has determined that a current provision of
our Floodplain Management Ordinance does not meet the minimum requirements of the National
Flood Insurance Program. Therefore, the City needs to bring Chapter 10 of City Code into
Compliance.
The proposed change involves how additions are included in the calculation of Substantial
Improvement. Under the new provision, the applicant will have two choices:
1. Design and certify the addition as “structurally independent” and elevate the addition.
The cost of the addition will not be included in the calculation of substantial
improvement.
2. Include the addition in the calculation of substantial improvement. The addition will be
required to be elevated.
- If the value of improvements, including the cost of the addition, is more than
50% of the value of the structure, then the existing structure will be considered
substantially improved and will need to be elevated.
Definition - Structurally Independent Addition - shall mean an addition that involves no alteration of
the load-bearing structure of the existing building, is attached to the building with minimal
connection, and has a doorway as the only modification to the common wall. A nonstructural
addition shall not transfer loads exerted on the addition to the existing building and thus shall not
share a foundation or other building elements that would create a load path between the addition
and the existing building. Shared heating, ventilation, and air conditioning (HVAC), electrical, and
plumbing between the addition and existing structure does not result in a structural connection.
This proposed regulation change does not apply to City-designated floodplains, such as Old Town.

Table of Odds for Different Events
Floodplain Facts
• Property in the 100-year floodplain has a 1 percent chance in any given year of being flooded.
• Over a 30-year period, there is a 26 percent chance that a property in the 100-year floodplain will be flooded. For comparison,
there is only a 5 percent chance that the building will catch fire during that same 30-year period.
• Some properties have an even higher risk of flooding because they are in areas where smaller, more frequent floods cause damage.

Floodplain Designations
• In Fort Collins, floodplains are designated by the City as well as by the Federal Emergency Management Agency (FEMA).
• The FEMA-basin floodplains cover only the major drainages. Changes in these floodplains must be approved by FEMA (p. 5).
• The City-basin floodplains further identify the flood hazard. Some of the flooding in City-basin floodplains is from irrigation ditch
spills or undersized storm sewers that result in overland flooding. Changes in these floodplains can be approved by the City (p. 5).
• For floodplain regulation purposes, a floodplain property is either in a FEMA-basin floodplain, a City-basin floodplain or the Poudre
River floodplain.

• The floodway is the portion of the floodplain with the greatest depths and velocities.
• The floodway is the area of highest risk.
• The floodway must be preserved to allow the floodwater to pass through without being obstructed.
• Areas along the flood fringe are allowed to be filled and developed, but this raises the 100-year flood level.
The City has set an allowable rise of 0.5 feet.

Floodway Modifications
• Floodways can be modified, but the applicant must be able to show that the project casues no-rise in the 100-year flood level.
• In FEMA-basin floodplains, the applicant must submit information to FEMA for approval before construction and after construction
if certain changes are being made.
If the applicant’s project causes a rise, there are two options:
1. In FEMA-basin floodplains, the applicant must show the entire rise is on their property or obtain easements from other property
owners. No structures can be impacted by a rise in the flood level.
2. In City-basin floodplains, the applicant must show that the entire rise is on their property or obtain easements from other
property owners.

If a substantial improvement occurs, the lowest
floor (p. 12-13) of a non-conforming structure,
including the basement, and all HVAC, electrical
and utilities, must be elevated 12 inches above the
flood elevation. After improvements, the structure
will be protected from flood damage.
If a redevelopment occurs, the lowest floor
(p. 12-13) of a non-conforming structure, including
the basement, all HVAC, electrical and utilities,
must be elevated 18 inches above the flood
elevation. After improvements, the structure will be
protected from flood damage.
elevated
12" or 18"
Substantial improvement occurs when all of the following conditions are met:
1. A building permit is requested for any repair, reconstruction or improvement to a non-conforming structure, involving alteration of
any wall, ceiling, floor or other structural part of the building;
2. The cost of the improvement, or the amount of damage, equals or exceeds 50 percent of the market value of the structure either
before the improvement or repair is started or before the building was damaged; and
3. The cost is calculated on a per project basis. A project is based on all building permits issued during the 12-month period
preceeding the floodplain permit application date.
A substantial improvement policy ensures that non-conforming structures are brought into conformance over time and are therefore,
protected from flood damage and the risk to occupants is reduced.
Redevelopment occurs when there is a substantial improvement and more than 50 percent of the wall perimeter of any floor of a
structure that is partially or completely below the flood elevation is removed or replaced and the building footprint is not increased.

Letter of Map Revision Based on Fill
• A Letter of Map Revision Based on Fill (LOMR-Fill) is a FEMA process whereby a property in the flood fringe can be filled and is no
longer considered in the floodplain for insurance requirements.
• A community must sign-off on the application to FEMA and certify that all existing and future structures will be “reasonably safe from
flooding.”
• To meet this “reasonably safe from flooding” standard, all floodplain requirements (p. 8-9) must be met even if fill is placed and the
property is “removed” from the floodplain by FEMA.

Erosion Buffer Limits
• Erosion hazard areas occur where the channel bed and banks are unstable, causing the stream to move over time.
• Migration is a natural characteristic of a stream. Some streams are more prone to migration than others depending on the type of
material that makes up the bed and banks.
• Urbanization can have a pronounced impact on these natural processes, resulting in accelerated erosion.
• Erosion buffer limits have been delineated for those streams that are subject to severe erosion hazards. These include Fossil Creek,
Boxelder Creek, McClellands Creek and Mail Creek.
• If development is restricted from these unstable areas, there will be less need in the future to defend the development from the
stream. Defending the development may solve one problem but could create another upstream or downstream.

Requirements within erosion buffer limits
• Structures are not allowed.
• Irrigated grasses or shrubs are not allowed.
• Detention ponds or water quality ponds are not allowed.
• Parking lots are not allowed.
• Temporary or permanent storage of materials is not allowed.
• The area within the buffer must not be used for construction traffic for any development.
• All utilities must be kept out except for necessary stream crossings.
• Bike paths must be kept out except for necessary stream crossings.
• Road bridges must span the entire buffer limit. If there is no possibility of spanning the entire limit, the location
crossing and design of abutments must be done so as to limit disturbance of the channel banks.
• Grading or excavation is not allowed in the buffer unless associated with a bridge or utility crossing as noted above.
• A stability study may be required.

Flood Insurance Information
Who needs flood insurance? EVERYONE. Flood Insurance is available for ALL properties in the City of Fort Collins,
regardless of location. Approximately 25% of damages occur in low risk areas.
Flood Insurance is required by lenders for any structure in a
FEMA 100-year floodplain.Lenders have the option of requiring
it in any other area.
• New flood insurance policies will require a FEMA Elevation
Certificate documenting the elevation of the structure.
• Fort Collins Utilities has elevation certificates on file for many
structures in the City of Fort Collins, free of charge, by calling
970-416-2632 or visiting www.fcgov.com/elevation-certificate.
• Documenting the elevation of the structure allows the flood
insurance premium to be calculated based on the risk.
• The higher the structure is elevated above the 100-year flood
level, the lower the insurance premium.
Flood Insurance is not mandatory in City-designated
floodplains. However, it is strongly recommended.
• Look into a “Preferred Risk” Flood Insurance Policy. It
combines structural coverage and contents coverage at a more
affordable price.
Important Considerations
• There is a 30-day waiting period before flood insurance
becomes effective.
• Disaster assistance is only available for major flood events
and does not cover the entire cost to rebuild your home or
business.
• Fort Collins is subject to flash flooding—there is little warning
time to move your contents to safer locations.
You can receive up to a 40% discount on your
flood insurance premiums.
• Fort Collins has some of the lowest flood insurance
premiums in the United States due to its proactive floodplain
management program.
• Check with your insurance agent to make sure you are
receiving the FEMA Community Rating System (CRS)
Discount for Fort Collins being a Class 4 Community.
To learn more, visit http://www.floodsmart.gov/, contact your
insurance agent, or call FEMA at 1-888-379-9531.

Table of Odds for Different Events
Floodplain Facts
• Property in the 100-year floodplain has a 1 percent chance in any given year of being flooded.
• Over a 30-year period, there is a 26 percent chance that a property in the 100-year floodplain will be flooded. For comparison,
there is only a 5 percent chance that the building will catch fire during that same 30-year period.
• Some properties have an even higher risk of flooding because they are in areas where smaller, more frequent floods cause damage.

Floodplain Designations
• In Fort Collins, floodplains are designated by the City as well as by the Federal Emergency Management Agency (FEMA).
• The FEMA-basin floodplains cover only the major drainages. Changes in these floodplains must be approved by FEMA (p. 5).
• The City-basin floodplains further identify the flood hazard. Some of the flooding in City-basin floodplains is from irrigation ditch
spills or undersized storm sewers that result in overland flooding. Changes in these floodplains can be approved by the City (p. 5).
• For floodplain regulation purposes, a floodplain property is either in a FEMA-basin floodplain, a City-basin floodplain or the Poudre
River floodplain.

• The floodway is the portion of the floodplain with the greatest depths and velocities.
• The floodway is the area of highest risk.
• The floodway must be preserved to allow the floodwater to pass through without being obstructed.
• Areas along the flood fringe are allowed to be filled and developed, but this raises the 100-year flood level.
The City has set an allowable rise of 0.5 feet.

Floodway Modifications
• Floodways can be modified, but the applicant must be able to show that the project casues no-rise in the 100-year flood level.
• In FEMA-basin floodplains, the applicant must submit information to FEMA for approval before construction and after construction
if certain changes are being made.
If the applicant’s project causes a rise, there are two options:
1. In FEMA-basin floodplains, the applicant must show the entire rise is on their property or obtain easements from other property
owners. No structures can be impacted by a rise in the flood level.
2. In City-basin floodplains, the applicant must show that the entire rise is on their property or obtain easements from other
property owners.

Freeboard
• Freeboard is a factor of safety that accounts for the allowed rise in flood level due to development in the flood fringe and for larger
floods and debris that may cause the flood elevation to be higher.
• Freeboard is a measure of how high above the flood level the structure must be built or floodproofed.
Residential Structures and Residential Portions of Mixed-Use Structures
• Freeboard is 24 inches;
• Must elevate the structure; not allowed to floodproof; and
• The lowest floor of the structure (p. 12-13), including the basement, all HVAC and electrical, must be elevated above the
freeboard height.

Freeboard continued
Floodproofing uses various techniques to make a
building water tight:
•Sealants and waterproof membranes;
•Closure shields in front of doorways; and
•Mini-walls to protect window or stair wells.
Floodproofing generally works only when flood
depths are less than 3 feet.

Substantial Improvement and Redevelopment
Residential Structures and Residential
Portions of Mixed-Use Structures
If a substantial improvement occurs, the lowest
floor (p. 12-13) of a non-conforming structure,
including the basement, and all HVAC, electrical
and utilities, must be elevated 24 inches above the
flood elevation. After improvements, the structure
will be protected from flood damage.
If a redevelopment occurs, the lowest floor (p.
12-13) of a non-conforming structure, including the
basement, all HVAC, electrical and utilities, must be
elevated 24 inches above the flood elevation. After
improvements, the structure will be protected from
flood damage.
Substantial improvement occurs when all of the following conditions are met:
1. A building permit is requested for any repair, reconstruction or improvement to a non-conforming structure, involving alteration of
any wall, ceiling, floor or other structural part of the building;
2. The cost of the improvement, or the amount of damage, equals or exceeds 50 percent of the market value of the structure either
before the improvement or repair is started or before the building was damaged; and
3. The cost is calculated cumulatively over the life of the structure during the time the structure has been located in a designated
floodplain.
A substantial improvement policy ensures that non-conforming structures are brought into conformance over time and are therefore
protected from flood damage and the risk to occupants is reduced.
Redevelopment occurs when there is a substantial improvement and more than 50 percent of the wall perimeter of any floor of a
structure that is partially or completely below the flood elevation is removed or replaced and the building footprint is not increased.

Letter of Map Revision Based on Fill
• A Letter of Map Revision Based on Fill (LOMR-Fill) is a FEMA process whereby a property in the flood fringe can be filled and is no
longer considered in the floodplain for insurance requirements.
• A community must sign-off on the application to FEMA and certify that all existing and future structures will be “reasonably safe from
flooding.”
• To meet this “reasonably safe from flooding” standard, all floodplain requirements (p. 8-9) must be met even if fill is placed and the
property is “removed” from the floodplain by FEMA.

or other drainage facility.
•In the floodway, all outside storage of material or equipment, including floatable materials, associated with any non-residential use is
not allowed.
•In the flood fringe, floatable materials associated with any non-residential use is not allowed.
•In the flood fringe, outside storage of material or equipment that is not considered “floatable material” is allowed.

Flood Insurance Information
Who needs flood insurance? EVERYONE. Flood Insurance is available for ALL properties in the City of Fort Collins,
regardless of location. Approximately 25% of damages occur in low risk areas.
Flood Insurance is required by lenders for any structure in a
FEMA 100-year floodplain.Lenders have the option of requiring
it in any other area.
• New flood insurance policies will require a FEMA Elevation
Certificate documenting the elevation of the structure.
• Fort Collins Utilities has elevation certificates on file for many
structures in the City of Fort Collins, free of charge, by calling
970-416-2632 or visiting www.fcgov.com/elevation-certificate.
• Documenting the elevation of the structure allows the flood
insurance premium to be calculated based on the risk.
• The higher the structure is elevated above the 100-year flood
level, the lower the insurance premium.
Flood Insurance is not mandatory in City-designated
floodplains. However, it is strongly recommended.
• Look into a “Preferred Risk” Flood Insurance Policy. It
combines structural coverage and contents coverage at a more
affordable price.
Important Considerations
• There is a 30-day waiting period before flood insurance
becomes effective.
• Disaster assistance is only available for major flood events
and does not cover the entire cost to rebuild your home or
business.
• Fort Collins is subject to flash flooding—there is little warning
time to move your contents to safer locations.
You can receive up to a 40% discount on your
flood insurance premiums.
• Fort Collins has some of the lowest flood insurance
premiums in the United States due to its proactive floodplain
management program.
• Check with your insurance agent to make sure you are
receiving the FEMA Community Rating System (CRS)
Discount for Fort Collins being a Class 4 Community.

Flooding is a natural process. A healthy ecosystem along the river relies upon
frequent inundations to survive and thrive. Floodplains help reduce flood
damage by allowing water to spread out over a large area. This reduces the
speed of floodwater as it is soaked up in wetlands like a sponge, lowering peak
flows downstream.
You can experience the natural beauty and wildlife habitats that help Fort Collins
be flood ready at over 17 conserved natural areas along the Cache la Poudre
River. Learn more at " #+2Ȑ +)ȩ* 01. ( .! /.
There are many City-conserved open spaces that also
reduce the flood hazard along Spring Creek, Fossil
Creek and other drainages.
Open space along waterways provides natural flood and erosion control, as
well as a place for us to enjoy the outdoors. Look for birds such as kingfishers,
great blue herons, redtail hawks, great horned owls and a diversity of migratory
songbirds that use drainage corridors, too.

You may think it’s OK for little things to be put down the storm drain, but it all
adds up and can create problems. Our storm drains run directly into our lakes
and streams and eventually to the Cache la Poudre River. To help keep them
clean, properly dispose of motor oil, pick up
grass clippings and pet waste, and use car
washes instead of washing your car at home.
Do not dump or throw anything into ditches
or streams. Obstruction and pollution of our
waterways and ditches are violations of Fort
Collins City Code.
Report any debris or dumping in ditches or
streams to Fort Collins Utilities at

Fort Collins has experienced numerous floods. The table below lists some of the
more notable floods in each of the city’s 12 drainage basins. Fort Collins is subject
to flooding from snowmelt on the Poudre River and flash flooding due to intense
thunderstorms. Typically, monsoon season runs from mid-July to mid-August, often
bringing heavy rainfall to Fort Collins. Some past floods, like the July 28, 1997 Spring
Creek Flood, are hard to forget. There are high water mark reminders along the
Spring Creek Trail, which document the 1997 flood. However, it does not take a large
flood to cause problems. Afternoon or evening thunderstorms can cause issues in
isolated areas, including street and basement flooding.

On May 22, 2018, an intense rain and hail storm tracked through Fort Collins.
Areas of town received 1.8 inches of rain in 30 minutes and hail accumulations to
depths of more than a foot. The hail clogged inlets, which resulted in localized
flooding. Numerous buildings were flooded in Old Town and on the CSU campus.
Motorists were stranded and had to be rescued. The following photos document
a few of these smaller floods that caused problems for motorists, homeowners
and businesses.
June 24, 1992 – An intense thunderstorm in Old Town caused the flooding of basements and many roads,
including near Moby Arena, pictured left.
August 2, 2007 – Street flooding near Shields Street
and Horsetooth Road.
June 6, 2009 – Flooding on Plum Street west of CSU.

Drainage Basins DatesDescriptionsCache la Poudre River1844, 1864, 1891, 1904, 1923, 1930, 1976, 1983, 1999, 2010, 2011, 2013 and 2014The three largest floods occurred in 1864, 1891 and 1904, with peaks of approximately 21,000 cubic feet per second (cfs). For comparison, the discharge of the Poudre River at “flood stage” is about 4,000 cfs. Flooding on the Poudre is primarily from snowmelt in late May and June. However, flash flooding can occur at any time. A severe flood has not occurred in more than 100 years.Spring Creek1902, 1904, 1938, 1949, 1951, 1961, 1977, 1983 and 1997The 1997 flood resulted in five deaths, destruction of 120 mobile homes and damage to 2,000 homes and businesses. This flood was considered to be greater than a 500-year event.Dry CreekNo serious flooding since about 1950The absence of even minor flooding is generally attributed to the network of irrigation canals that have some capacity for intercepting small to moderate Dry Creek flows.Fossil Creek1902, 1938, 1965, 1977, 1979, 1997, 1999 and 2007Fossil Creek is relatively undeveloped and past floods have gone unnoticed. In addition to flooding hazards, Fossil Creek also is susceptible to bank erosion.Boxelder Creek/ Cooper Slough 1909, 1922, 1930, 1937, 1947, 1963, 1967, 1969 and 2007Boxelder Creek has a drainage area of 251 square miles, and 176 square miles now are controlled by Soil Conservation Service flood control dams near Wellington.Old Town Basin1904, 1933, 1938, 1951, 1977, 1983, 1988, 1992, 1997, 2009 and 2018Street flooding is the primary problem in this basin.Canal Importation Basin1938, 1951, 1975, 1992, 1997, 1999 and 2009There are several small drainage areas in this basin. Development prior to drainage criteria encroached on the channels, reduced the flow capacity and caused flooding. The irrigation canals also overflow their banks and cause flooding.West Vine Basin1980, 1997 and 1999 (Past floods were not well documented.)Localized flooding occurs due to encroachment on drainages and from irrigation ditch spills.(++ ˏ%/0+.5ˏ *"+.) 0%+*.+0! 0%*#ˏ"+.ˏ0$!ˏ101.!The Master Drainage Plan includes plans for the 12 stormwater basins across the city. The purpose is to identify stormwater management issues and develop solutions that reduce flood risk, improve stormwater quality and promote stream rehabilitation. Each plan looks at the unique characteristics of the basin, identifies potential problems, and provides an alternative analysis and recommended improvements. Utilities prioritizes all stormwater and stream rehabilitation projects on an annual basis. The main categories used to evaluate each project include protection of structures from flooding, road overtopping, cost-benefit ratio, health and safety, water quality and habitat improvement.

All rivers, streams, tributaries and canals – regardless of size – have the potential to flood. In Fort Collins, major sources of flooding include the Cache la Poudre River,
Spring Creek, Dry Creek, Fossil Creek and Boxelder Creek. Urban street flooding also is a hazard. All drainage basins flow to the Cache la Poudre River.OverlandTrlLaurel St
