EXECUTIVE SUMMARY
The Ordinance modifies City Code to change the floodplain regulations for the Poudre River.
Properties in the Poudre River floodplain in the City of Fort Collins are subject to different
regulations than those located in Latimer County. City and County staffs have developed
recommendations that would address most of the problems created by the different regulations.
Public outreach was performed during the formulation of the regulation changes which included
notices to owners of properties ` ()Pn
-Ci and the County about an open
house,presentations to special teresti County boards and commissions
and information posted on the s wcil di ussed this item at its December 12,
2006 work session.
BACKGROUND
Floodplain regulations were first adopted in the City in the mid 1970's for the Poudre River. The
City of Fort Collins entered the National Flood Insurance Program in 1979 with the adoption of
January 16, 2007 -2- Item No. 28
floodplain regulations for the Poudre River, Spring Creek, and Dry Creek basins. Undeveloped
properties located in a floodplain can develop as long as they comply with the floodplain regulations.
Properties in the Poudre River floodplain in the City of Fort Collins are subject to different
regulations than those located re numerous problems during
development and annexation cess�e . e a o d ast erry Corridor Plan directed City
and County staffs to review th oudre ver fl d am reguI ions to make them as consistent as
possible. �"1_1 ' a 0
Floodplain Maps and Property Statistics
A map of the Poudre River floodplain within the City's Growth Management Area is Attachment
1. The 100-year 0.5-foot floodway(areas of greatest risk with high depths and velocities)are shown
in dark blue. The 0.1-foot floodway is shown in the yellow outside of the 0.5-foot floodway. The
Product Corridor is delineated by a red line. The 100-year flood fringe is shown in light blue. The
moderate risk areas,shown in green,are either the existing Federal Emergency Management Agency
(FEMA)500-year floodplains or areas of sheet flow in the 100-year floodplain with less than 1-foot
of depth. Attachment 2 shows this same information with properties in public ownership
highlighted.

Proposed Floodplain Regulation Changes
Staffs from both the City and County compared their respective regulations. There were eight areas
of disagreement between the City and County regulations identified as a part of this project.
Keeping in mind there are some areas where both the City would become less restrictive and the
County would become more restrictive, the recommended changes include five areas where the
City's regulations would become less restrictive, four areas where the County's regulations would
become more restrictive, and one area where City and County staffs could not reach agreement,
resulting in an ongoing difference in regulation.
Attachment 4 is a summary table listing the proposed changes for both the City and County. These
recommendations represent a nCan7ci
oodl
pg�ulation
1 rbcing risk with regulation. The
importance of protecting anda ctions of the river were also
considered. Attachment 5, "P e Poudre River Quick Guide"
was prepared to help illustrate
Of the five areas where City staff is recommending City regulations be made less restrictive, two
are proposed to be totally eliminated because they do not balance risk with regulation and are
ineffective or are technically difficult to administer.
Details of the proposed changes and the sections of City Code to be modified are as follows.
January 16, 2007 -3- Item No. 28
Changes to Align City-County Regulations
Floodway Definition
Current City Code defines th ood�a or th P dr Ri a rise of 0.1-foot. The current
County floodway rise definitio is 0.5-f t. c ent offic FEMA floodway is based on a 1-
footrise definition. It is propos e�it d ge its way to the County's 0.5-foot rise
definition.
• Section 10-16 Definitions—Floodway
Floodway Modification
Current City Code states that only the City can modify the floodway for public infrastructure or
publicly owned recreation facilities as long as there is a no-rise condition, channel stability is
maintained and the natural environment along the river is either protected or enhanced. Current
County regulations state that floodway modification is allowed byboth the public and private sectors
as long as the no-rise criterion is met. It is proposed the County would add the channel stability and
environmental considerations criteria. The City would not change its criteria except to allow
floodway modification by both public and private entities.

Critical Facilities in the 100-year Floodplain
Critical facilities are made up of three categories: life safety, emergency response and hazardous
materials. The County does not have regulations pertaining to critical facilities in the 100-year
floodplain. The City has regulations prohibiting critical facilities in the 100-year floodplain. It is
proposed the County add the provision that life safety and emergency response critical facilities not
be allowed in the 100-year floodplain. However, City and County staff have not reached an
agreement on the hazardous materials criteria. City staff believes that it should be included and
County staff is hesitant to include the provision due to the anticipated large number of parcels with
hazardous materials in the Airpark area. At the work session some members of Council encouraged
the County to adopt the City stand f r h ou eriYC'i
affrecommends the City Code
not be changed regarding this ' ue. resu m nd County regulations do not
agree on this issue.
Critical Facilities in the 500-Year Floodplain
Current City Code does not allow critical facilities, including life safety, emergency response, and
hazardous materials facilities in the 500-year floodplain. The County does not regulate critical
facilities in the 500-year floodplain. The County would begin regulating life safety and emergency
response critical facilities in the 500-year floodplain. The City would continue to regulate life safety
January 16, 2007 -4- Item No. 28
and emergency response critical facilities but would allow hazardous material critical facilities in
the 500-year floodplain.
• Section 10-81 S t fo e e-hundred-year floodplain and
zone X shaded eas
Freeboard Level
The current freeboard requirement in the County is 18-inches. The City's requirement is 24-inches.
It is proposed the County will change the freeboard requirement to 24-inches consistent with the
City'S.
Letter of Map Revision (LOMR)-Fill Requirements
Currently FEMA requires local governments to sign off on LOMR-Fill applications stating that
structures are safe from flooding when structures are removed from the floodplain through the
LOMR-Fill process. Currently the City has a provision requiring that structures must be elevated
24-inches above the flood elevation and not allowing critical facilities in LOMR-Fill areas. The
County currently doesn't have these provisions. It is proposed the County would add the 24-inch
freeboard and the no new critical facilities criteria in LOMR-Fill areas.
Changes to Balance Risk wkRegu on an e I dive Provisions
(Also Aligns City-County Rens�
Product Corridor
Current City Code defines the Product Corridor using 500-year discharges as an area when the
velocity times the depth is six. No encroachment and no variances are allowed in the Product
Corridor. Staff has found this regulation to be excessive,not allowing for special circumstances and
technically impractical to administer due to difficulty in making accurate determinations. The
product corridor is also a redundant layer of regulation, since the area in the 500-year product
corridor is substantially the same as the 100-year floodway. Currently the County does not have a
product corridor regulation. It is proposed the City would remove from the Code the provisions or
references pertaining to the Product Corridor.

Dryland Access
Current City Code states that new development must have dry access to any new structure. Staff has
found that often times offsite roads leading to a property are under water making the requirement
irrelevant and variances are often granted. Current County regulations do not have a dryland access
regulation. It is proposed that the City remove from the Code the provisions or references pertaining
to the dryland access.

Housekeeping Changes P Y
There are some minor "housekeeping" items that are included in the proposed changes. These
changes are needed to make the context of the Code language consistent throughout. The definition
for redevelopment was changed to make it consistent with the definition that applies to other
floodplains citywide. The LOMR-Fill section was reworded to make it consistent as well. Changes
to the code have also been made to include reference to FEMA's Physical Map Revision (PMR)
process.
Community Rating System and Flood Insurance Considerations
All structures in Fort Collins are eligible for flood insurance regardless of whether they are located
in a floodplain or not. The cost of flood insurance depends on many variables including amount of
coverage,deductibles,type of structure,and how high the structure is elevated above the flood level.
The FEMA Community Ratin yste RS o t i entive program that encourages
communities to go beyond FE A mini um re i is fo oodplain management. Based on
a rating of numerous storm e t tivities blic outreach, higher regulatory
standards, drainage system maintenance, flood warning,preservation of open space, etc.)residents
and businesses of a community receive a discount on their flood insurance premiums. The City of
Fort Collins currently has one of the highest CRS ratings in the nation,providing our customers with
a 30% discount on flood insurance premiums. It is anticipated the changes included in the
Ordinance would not change the City's CRS rating. None of the proposed changes are below FEMA
minimum standards.
January 16, 2007 -6- Item No. 28
Public Outreach
A variety of communication tools such as floodplain property owner customer notices,information
on the City's web page, a preCs , s o houses, and outreach to both
internal and external groups p fect d. entations were made to fourCityBoards and Commissions a Co 1 a wor ession tosolicitcomments and
recommendations. A joint Co e use w eld to solicit comments from the
public on the proposed changes. Meetings were also held with the Mulberry Corridor Owner's
Association and the Chamber's Local Legislative Affairs Committee. The County held meetings
with County boards and commissions as well.
The City of Fort Collins
Following is a summary of discussion of the various boards and commissions. Excerpts of the
minutes from the Water Board, Land Conservation and Stewardship Board and Natural Resources
Advisory Board are included as Attachment 6. There are no minutes available from the Planning
and Zoning Board because they discussed this item at a study session.
The Water Board formally passed a motion (7-2) in support of the proposed changes with
Alternative 2, to not allow hazardous materials critical facilities in the 100-year floodplain. Two
members did not support the mo ' a f C' sh n't lower any of its regulations
for the Poudre River.
The Planning and Zoning Boar ss to a stud ssion and it was the consensus of
the members present to support the proposed changes with Alternative 2, to not allow hazardous
materials critical facilities in the 100-year floodplain. One member did not voice their opinion
because they felt they did not have enough information to express an opinion.
The Land Conservation and Stewardship Board did not act on the proposed changes as a whole.
They supported staff s minimum recommendation to remove the product corridor and dryland access
regulations. They also supported staff s proposal to add stability and environmental factors to the
County's floodway modification regulations.Finally,they recommended Council adopt Alternative
2, to not allow hazardous material critical facilities in the 100-year floodplain. The Board did not
take action on the other staff recommendations because they felt it was not under their area of
expertise to offer a recommendation.
The Natural Resources Advisory Board discussed this item at two of its meetings and formally
passed a motion unanimously i rt Y
ation of hazardous materials in
the 100-year floodplain due to ncem out t it mpacts of hazardous materials in
flood waters. The Board chos of to t a po i on ther recommended changes.
On December 12, 2006 City Council held a work session on the proposed regulation revisions(see
Attachment 7). The following key discussion points were raised:
• Development of the recommended changes was done in the spirit of compromise of trying
to bring the City and County regulations closer together.
January 16, 2007 -7- Item No. 28
• The approach to balancing risk with regulation for the floodplain regulations seemed
reasonable to protect people and property,however, it was also pointed out that floodplain
regulations also protect the natural beneficial functions of the river.
• The proposed changes w' dPY�
the river corridor,but will also
have some environrne 1 benef in e ridor as well.
• One member of Counci aised nce wer to the County level,when
the County should be goi the s 1regulation.
• A majority of the Council supported the staff recommendation; however, concerns were
expressed regarding the elimination of the product corridor regulations and going from a 0.1-
foot floodway to a 0.5-foot floodway.
Larimer County
The Board of County Commissioners and County Planning Commission held a work session on
November 8, 2006 to discuss the proposed changes. County staff presented history and salient
points of the proposed changes to the floodplain regulations. Clarification was made that on a lot
with an existing structure, any new structure would need to be 24-inches above the flood elevation
or an increase of 6-inches over the current regulations. The question was raised if the proposed
requirements for floodway modification would prevent "channelization" or narrowing of the
floodway and staff responded that the language regarding stability was intended to do just that,
although additional language t . a rop ' to c me was made given the degree of
effort that has been expended staff; y wo d se e effort move forward in a timely
manner if possible.
The County Planning Commission is scheduled to consider this item on January 17, 2007.
The Board of County Commissioners is scheduled to consider this item on January 22, 2007. Any
adjustments to the City's proposed changes resulting from the County Commissioner's action on
January 22, 2007 will be made between the City's First and Second Reading.
Other Outreach
A joint open house for both the City and County was held on November 14th at the Lincoln Center.
Approximately 3,500 notices were mailed to city and county property owners in the floodplain along
with a press release in the newspaper advertising the open house. Approximately 55 property owners
attended the open house. At the open house comment sheets were available to solicit comments
from those attending the open Cated
re Pere
er ed requesting copies of the
open house materials and onemor sh d e directed toward flood control
projects. One citizen stated at th aons floatable material should be less
restrictive. Other verbal comm t ov in favor of the proposed changes.
On December 12, 2006 City and County staff presented the proposed revisions to the Mulberry
Corridor Owner's Association. A few clarification questions were raised and no adverse comments
were received.
January 16, 2007 -8- Item No. 28
On December 1, 2006 City staff presented the proposed revisions to the Chamber of Commerce
Local Legislative Affairs Committee. During the discussion questions were answered clarifying the
proposed changes with comments overall in favor of the recommendations.

Poudre River floodplain regulations are similar and the ways in which they are different; and
WHEREAS,some current regulations are not based on a national standardized methodology
and some current regulations have not achieved their intended purposes and therefore need to be
revised; and
WHEREAS, a great deal of the Poudre River corridor is preserved as open space and
provides flood protection because of limited development subject to flooding; and
WHEREAS,based on this information, City and County staff developed recommendations
intended to establish common criteria while still balancing risk with regulation and recognizing the
natural features of the river corridor; and
WHEREAS,the City and County conducted outreach activities with the public and affected
property owners concerning the proposed revisions to the floodplain regulations; and
WHEREAS,the proposed revisions to the floodplain regulations have been reviewed by the
City's Water Board, Planning and Zoning Board, Natural Resources Advisory Board and Land

from the public and affected property owners during the outreach, City and County staff have
proposed new floodplain regulations for the Poudre River, and the revisions to the City's Poudre
River floodplain are contained in this Ordinance; and
WHEREAS,the Water Board took formal action recommending that the City Council adopt
the proposed floodplain revisions; and
WHEREAS,staff presented the proposed changes to the floodplain regulations to the Council
at a work session on December 12, 2006 and at that time received direction to present the same to
the Council for approval; and
WHEREAS,staff is also recommending certain format changes to existing portions of Article
II of Chapter 10 to make the Code language consistent in form and easier to understand; and
