Report
To: Honorable Mayor Hall & Board of Trustees
Estes Valley Fire Protection District Board of Directors
Through: Town Administrator Machalek
From: Jon Landkamer, Division Chief of Support Services
Stacey Sutherland, Fire Code Inspector II/ Captain
Steve Careccia, Community Development Director
Dan Wester, Chief Building Official
Date: February 13, 2026
Subject: Colorado Wildfire Resiliency Code
Purpose of Study Session Item:
Provide the Town Board and Board of Directors with an overview of the draft Colorado
Wildfire Resiliency Code (Code) with local amendments proposed for adoption by the
Estes Valley Fire Protection District and ratification by the Town of Estes Park. Division
Chief Landkamer will lead the presentation at the study session.
Town Board Direction Requested:
Direction from the Town Board and Board of Directors is sought on the provisions and
proposed local amendments contained within the attached Code.
Present Situation:
The Colorado Department of Public Safety, Division of Fire Prevention and Control,
through establishment of a Wildfire Resiliency Code Board, adopted the Colorado
Wildfire Resiliency Code on June 1, 2025. This model code establishes minimum
standards for the protection of life and property from the hazards of wildfire. As a model
code establishing minimum standards, municipalities may adopt more restrictive
standards through local amendments, but not less restrictive.
Municipalities are required to adopt wildfire regulations that meet or exceed those
established in the State model code by April 1, 2026. Municipal compliance with the
adopted code is required by July 1, 2026.
Proposal:
The attached Code (Attachments 1&2) is the State model code with local amendments
proposed by the Fire Protection District. The local amendments are similar to those
recently adopted by Larimer County, but modified to better reflect the context of the
Estes Valley.
General provisions of the draft Code and local amendments include:
1. Applicability to the entire Estes Valley Fire Protection District (including
incorporated Estes Park town limits) versus use of the adopted State map, which
excludes portions of the Town and District from the Code.
ADOPTED STATE MAP (Estes Valley Area)
2. Removal of Low, Moderate, and High Fire Intensity Classifications, as adopted in
the State model code, in favor of designating the entire Fire Protection District as
a Wildland-Urban Interface area subject to a uniform application of the Code’s
requirements (Attachment 3).
3. Establishes structure hardening requirements (e.g. use of ignition-resistant or
noncombustible materials) for buildings and structures. Applies such
requirements uniformly to all buildings and structures within the Fire Protection
District, rather than using separate Class 1 and Class 2 designations having
different requirements based on fire intensity (Low, Moderate, High), as adopted
in the State model code.
4. Establishes site and area requirements applicable to all land within the Fire
Protection District rather than using separate Class 1 and Class 2 designations
having different requirements based on fire intensity (Low, Moderate, High), as
adopted in the State model code. Such requirements establish Structure Ignition
Zones (0-5 feet, 5-30 feet, 30-100 feet) around a building or structure, with
prohibitions on what can be planted and installed within these zones.
5. Code requirements apply to:
a. New buildings and structures (not retroactively applied to legal existing
buildings and structures);
b. Additions or alterations that increase the existing building or structure
footprint by 500 square feet or more;
c. Total roof cover of a building or structure when 25% or more of the roof
cover is proposed for replacement, reconstruction, alteration, or repair;
d. Total exterior wall area of a building or structure when 25% or more of the
total exterior wall area is proposed for replacement, reconstruction
alteration, or repair;
e. Fencing within eight feet of a habitable building or structure.
6. Establishes a Code Official to administer and enforce the Code (intended to be
the Fire Chief for the Fire Protection District and the Chief Building Official for the
Town).
7. Requires permits for applicable construction (i.e. a new permit for fencing is
proposed).
8. Establishes criteria for the preparation and submittal of construction documents
(e.g. site plans, building/structure footprints, landscaping and vegetation,
topography, defensible space) with application for building permits.
Some exceptions to the Code’s requirements include:
1. Interior alterations of existing buildings and structures;
2. Painting, staining, and similar restorative or maintenance work;
3. One-story, detached accessory structures not intended for habitation (e.g. sheds)
located at least 10 feet from an occupiable structure and less than 200 square
feet (residential) and 120 square feet (non-residential) in area;
4. Certain accessory buildings and structures (i.e. used for utility or agricultural
purposes) located more than 50 feet from a habitable/occupiable structure;
5. Fences more than eight feet from a habitable structure.
The Town (Community Development Building Division) will assume primary
responsibility for implementing the Code’s structure hardening requirements through the
intake, processing, and review of building permits and inspection of associated
improvements. The Fire Protection District will assume primary responsibility for the
review and inspection of site and area requirements. Clarification of responsibilities and
other administrative functions will be further addressed through consideration of a
cooperative agreement resolution during the adoption and ratification of the Code.
Advantages:
• Increased protection of property and life from wildfire hazards
• Implementing measures to protect property and life from wildfire hazards is an
established goal within the Estes Forward Comprehensive Plan
• Potential to create conditions for increased insurability of buildings, structures,
and property
Disadvantages:
• Portions of Estes Park and the Estes Valley are excluded from the high wildfire
hazard zones on the adopted State Map
• Implementing the Code may require additional permits (e.g. fence permit),
inspections, and longer review times to ensure compliance with the Codes
requirements
• Enforcement of site and area requirements could result in property owners
having to remove or severely prune existing trees and vegetation on their
property
• Construction costs may increase due to new requirements for fire-hardened
building materials and construction methods
Finance/Resource Impact:
Administration and enforcement of the Code’s provisions will require significant staff
time and resources (without additional State funding).
Level of Public Interest:
It is anticipated that public interest will be moderate.
Feedback received from the Development Code update’s public engagement efforts
indicate there is broad community support for wildfire mitigation measures in general but
mixed support for required landscape and vegetation removal as part of defensible
space efforts.

Chapter 1 - Scope and Administration
PART 1 GENERAL PROVISIONS
SECTION 101 SCOPE AND GENERAL REQUIREMENTS
The following section is hereby amended to read as follows:
101.1 Title. These regulations shall be known as the Colorado Wildfire Resiliency Code as
adopted by Estes Valley Fire Protection District, hereinafter referred to as “this code.”
101.2 Scope. The provisions of this code shall apply to the construction, alteration,
movement, repair, maintenance and use of any building, structure or premises that contain
occupiable and/or habitable space, or change in use resulting in an occupiable and/or
habitable space, unless excepted, within the wildland-urban interface areas of Colorado,
as designated in this code. Buildings or conditions in existence at the time of the adoption
of this code are allowed to have their use or occupancy continued, if such condition, use or
occupancy was legal at the time of the adoption of this code, provided that such continued
use does not constitute a distinct danger to life or property.
Buildings or structures moved into or within the jurisdiction shall comply with the provisions
of this code for new buildings or structures.
101.2.1 Appendices. Provisions in the appendices shall not apply unless specifically
adopted.
101.2.2 Factory-built structures (non-residential, residential, and tiny homes).
Structure hardening provisions of this code for factory-built structures as defined by
sections 24-32-3302(9), (10), (11), and (35), C.R.S., are in accordance with Rules
adopted by the Division of Housing in 8 CCR 1302-1, Rule 2 Codes and Standards.
101.2.3 HUD code homes. Homes built to the Housing and Urban Development
(HUD) Manufactured Home Construction and Safety Standards are exempt from
structure hardening requirements on their first installation. Homes built to the HUD
Manufactured Home Construction and Safety Standards which are moved into an
applicable Wildfire Resiliency code area are subject to the provisions of this code as
required by the authority having jurisdiction.
101.3 Purpose. The purpose of this code is to establish minimum regulations for the
safeguarding of life and for property protection. Regulations in this code are intended to
mitigate the risk to life and structures from intrusion of fire from wildland fire exposures and
fire exposures from adjacent structures and to mitigate structure fires from spreading to
wildland fuels. The extent of this regulation is intended to be tiered commensurate with the
relative level of hazard present.
The unrestricted use of property in wildland-urban interface areas is a potential threat to life
and property from fire and resulting erosion. Safeguards to prevent the occurrence of fires
and to provide adequate fire protection facilities to control the spread of fire in wildland-urban
4 | P a g e
interface areas shall be in accordance with this code.
This code shall supplement the jurisdiction’s building and fire codes, if such codes have
been adopted, to provide for special regulations to mitigate the fire- and life-safety hazards
of the wildland-urban interface areas.
101.4 Retroactivity. The provisions of the code shall apply to conditions arising after the
adoption thereof, conditions not legally in existence at the adoption of this code and
conditions that, in the opinion of the code official, constitute a distinct hazard to life or
property.
Exception: Provisions of this code that specifically apply to existing conditions are
retroactive.
101.5 Additions or alterations. Additions or alterations shall be permitted to be made to
any building or structure without requiring the existing building or structure to comply with
all of the requirements of this code, provided that, when the work increases the footprint of
the existing structure by 500 square feet or greater, the addition or alteration conforms to
that required for a new building or structure.
Exception: Provisions of this code that specifically apply to existing conditions are
retroactive.
Additions or alterations shall not be made to an existing building or structure that will cause
the existing building or structure to be in violation of any of the provisions of this code nor
shall such additions or alterations cause the existing building or structure to become unsafe.
An unsafe condition shall be deemed to have been created if an addition or alteration will
cause the existing building or structure to become structurally unsafe or overloaded; will not
provide adequate access in compliance with the provisions of this code or will obstruct
existing exits or access; will create a fire hazard; will reduce required fire resistance or will
otherwise create conditions dangerous to human life.
101.6 Roof coverings. The roof covering on buildings or structures in existence prior to
adoption of this code that are replaced or have 25 percent or more of the surface area of
the roof replaced, or where work to reconstruct, alter, or repair the roof covering effectively
replaces such material, shall require the entirety of the roof covering to be replaced with a
roof covering required for new construction specified in Sections 403.2 through 403.2.2.
Exception: Existing roof coverings that are compliant with Section 403.2.
101.7 Exterior walls. The exterior walls of building or structures in existence prior to
adoption of this code where 25 percent or more of the total exterior wall surface area is
replaced, or where work to reconstruct, alter or repair the exterior walls effectively replaces
the exterior wall material, shall require the entirety of the exterior wall surface area, including
attachments, to be replaced with materials required for new construction specified in Section
403.6 through 403.6.2 and the immediate zone within 5 feet of the structure shall be made
to comply with Section 503.1.
Exception: Existing exterior walls that are compliant with Section 403.6.
5 | P a g e
101.8 Maintenance. Buildings, structures, landscape materials, vegetation, defensible
space or other devices or safeguards required by this code shall be maintained in
conformance to the code edition under which installed. The owner or the owner’s authorized
agent shall be responsible for the maintenance of buildings, structures, landscape materials
and vegetation.

PART 1 GENERAL PROVISIONS
SECTION 101 SCOPE AND GENERAL REQUIREMENTS
The following section is hereby amended to read as follows:
101.1 Title. These regulations shall be known as the Colorado Wildfire Resiliency Code as adopted
by Estes Valley Fire Protection District, hereinafter referred to as “this code.”
101.2 Scope. The provisions of this code shall apply to the construction, alteration, movement,
repair, maintenance and use of any building, structure or premises that contain occupiable and/or
habitable space, or change in use resulting in an occupiable and/or habitable space, unless
excepted, within the wildland-urban interface areas of Colorado, as designated in this code.
Buildings or conditions in existence at the time of the adoption of this code are allowed to have
their use or occupancy continued, if such condition, use or occupancy was legal at the time of the
adoption of this code, provided that such continued use does not constitute a distinct danger to life
or property.
Buildings or structures moved into or within the jurisdiction shall comply with the provisions of this
code for new buildings or structures.
101.2.1 Appendices. Provisions in the appendices shall not apply unless specifically adopted.
101.2.2 Factory-built structures (nonresidential, residential, and tiny homes). Structure
hardening provisions of this code for factory-built structures as defined by sections 24-32-3302(9),
(10), (11), and (35), C.R.S., are in accordance with Rules adopted by the Division of Housing in 8
CCR 1302-1, Rule 2 Codes and Standards.
101.2.3 HUD code homes. Homes built to the Housing and Urban Development (HUD)
Manufactured Home Construction and Safety Standards are exempt from structure hardening
requirements on their first installation. Homes built to the HUD Manufactured Home Construction
and Safety Standards which are moved into an applicable Wildfire Resiliency code area are subject
to the provisions of this code as required by the authority having jurisdiction.
101.3 Purpose. The purpose of this code is to establish minimum regulations for the safeguarding of
life and for property protection. Regulations in this code are intended to mitigate the risk to life and
structures from intrusion of fire from wildland fire exposures and fire exposures from adjacent
structures and to mitigate structure fires from spreading to wildland fuels. The extent of this regulation
is intended to be tiered commensurate with the relative level of hazard present.
The unrestricted use of property in wildland-urban interface areas is a potential threat to life and
property from fire and resulting erosion. Safeguards to prevent the occurrence of fires and to provide
adequate fire protection facilities to control the spread of fire in wildland-urban interface areas shall
be in accordance with this code.
4 | P a g e
This code shall supplement the jurisdiction’s building and fire codes, if such codes have been adopted,
to provide for special regulations to mitigate the fire- and life-safety hazards of the wildland-urban
interface areas.
101.4 Retroactivity. The provisions of the code shall apply to conditions arising after the adoption
thereof, conditions not legally in existence at the adoption of this code and conditions that, in the
opinion of the code official, constitute a distinct hazard to life or property.
Exception: Provisions of this code that specifically apply to existing conditions are retroactive.
101.5 Additions or alterations. Additions or alterations shall be permitted to be made to any building
or structure without requiring the existing building or structure to comply with all of the requirements
of this code, provided that, when the work increases the footprint of the existing structure by 500
square feet or greater, the addition or alteration conforms to that required for a new building or
structure.
Exception: Provisions of this code that specifically apply to existing conditions are retroactive.
Additions or alterations shall not be made to an existing building or structure that will cause the
existing building or structure to be in violation of any of the provisions of this code nor shall such
additions or alterations cause the existing building or structure to become unsafe. An unsafe condition
shall be deemed to have been created if an addition or alteration will cause the existing building or
structure to become structurally unsafe or overloaded; will not provide adequate access in compliance
with the provisions of this code or will obstruct existing exits or access; will create a fire hazard; will
reduce required fire resistance or will otherwise create conditions dangerous to human life.
101.6 Roof coverings. The roof covering on buildings or structures in existence prior to adoption of
this code that are replaced or have 25 percent or more of the surface area of the roof replaced, or
where work to reconstruct, alter, or repair the roof covering effectively replaces such material, shall
require the entirety of the roof covering to be replaced with a roof covering required for new
construction specified in Sections 403.2 through 403.2.2.
Exception: Existing roof coverings that are compliant with Section 403.2.
101.7 Exterior walls. The exterior walls of building or structures in existence prior to adoption of
this code where 25 percent or more of the total exterior wall surface area is replaced, or where work
to reconstruct, alter or repair the exterior walls effectively replaces the exterior wall material, shall
require the entirety of the exterior wall surface area, including attachments, to be replaced with
materials required for new construction specified in Section 403.6 through 403.6.2 and the immediate
zone within 5 feet of the structure shall be made to comply with Section 503.1.
Exception: Existing exterior walls that are compliant with Section 403.6.
101.8 Maintenance. Buildings, structures, landscape materials, vegetation, defensible space or other
devices or safeguards required by this code shall be maintained in conformance to the code edition
under which installed. The owner or the owner’s authorized agent shall be responsible for the
maintenance of buildings, structures, landscape materials and vegetation.

Chapter 3 - Wildfire Hazard Identification
SECTION 301 GENERAL
301.1 Scope. The provisions of this chapter provide methodology to establish and record wildfire
hazard based on the findings of fact to be regulated by this code.
301.2 Objective. The objective of this chapter is to provide simple baseline criteria for
determining wildland-urban interface areas based on the wildfire hazard.
SECTION 302 WILDLAND-URBAN INTERFACE AREA DESIGNATIONS
The following section is hereby amended to read as follows:
302.1 Declaration. The AHJ shall declare the wildland-urban interface areas within the jurisdiction
as defined by this code. The wildland-urban interface areas shall be based on the findings of fact.
Because of the history of and potential for large, destructive wildland fires, all of Estes Valley Fire
Protection District is deemed a wildland-urban interface area. Structures and parcels shall be
constructed and maintained in accordance with the provisions for structure hardening of Chapter 4
and site and area requirements of Chapter 5.
SECTION 303 MAPPING AND APPLICABILITY
303.1 Mapping of Wildfire Hazard Areas.
Wildfire Hazard shall be recorded on official maps. These maps identify areas subject to the
provisions of this code and shall be available for public inspection through an accessible online
platform and at designated local government offices.
303.1.1 Map. This map shall be based on a combination of factors including, but not limited to,
vegetative fuels, topography, local weather patterns, and fire behavior modeling data.
The following section is hereby amended to read as follows:
303.1.2 Locally Developed Mapping.
The AHJ may develop and adopt local maps designating wildfire hazard and fire intensity
classifications areas within its jurisdictional boundaries in accordance with Sections 303.1 through
15 | P a g e
303.3.
The following section is hereby deleted in its entirety:
303.2 Fire Intensity Classification. Fire Intensity Classification shall be identified on the map in
accordance with Section 303.1. Fire Intensity Classification is determined by expected wildfire
behavior, including flame length and suppression difficulty and is separated into three levels: low,
moderate, and high. The identified fire intensity classification establishes code requirements for
construction and mitigation.
The following section is hereby deleted in its entirety:
303.2.1 Low Fire Intensity Classification. Low Fire Intensity Classification is identified in areas
with light to medium surface fuels, such as grasses, shrubs, and scattered
low-density vegetation. These fuels are often discontinuous, which limits flame propagation but
can sustain burning under moderate weather conditions. Fires in this class may occur on gentle to
moderate slopes, where topography begins to influence the rate of spread. Although flame lengths
remain relatively small, typically less than two feet limited spotting may occur, especially with
wind. Trained firefighters with protective equipment and standard hand tools can usually suppress
these fires through direct attack, particularly on slopes under 30 percent. Mechanized equipment is
typically unnecessary.
Key Characteristics Include:
1. Fuels: Light to medium surface fuels, including grasses, shrubs, and scattered vegetation
(e.g., WNL, USL fuel types).
2. Flame Length: Less than 2 feet.
3. Rate of Spread: Low, increasing with slopes over 20 percent.
4. Spotting: Very short-range spotting is possible under windy conditions.
5. Terrain Influence: More active fire behavior on moderate slopes (20 to 30 percent).
6. Suppression Difficulty: Easily suppressed by trained firefighters using basic protective
gear and hand tools. Direct attack is effective, and mechanized support is rarely needed.
The following section is hereby deleted in its entirety:
303.2.2 Moderate Fire Intensity Classification. Moderate Fire Intensity Classification is
identified in areas with moderate to heavy fuel loads, such as dense shrubs, small trees, and
accumulated ground fuels. Fires in this class present continuous horizontal and vertical fuel
arrangements, allowing flames to reach up to 8 feet in length. Fire behavior is notably influenced
by moderate to steep slopes, often accelerating the spread.
Short-range spotting becomes more common, complicating suppression efforts. Ground crews
typically require mechanized support, such as engines and dozers, to establish control lines. Aircraft
assistance may be necessary, particularly in inaccessible terrain. There is a significant increase in the
potential for property damage and risk to life, especially in wildland-urban interface areas.
Key Characteristics Include:
1. Fuels: Moderate to heavy fuels, including dense shrublands, small trees, timber litter, and
canopy fuels (e.g., USH, UIH fuel types).
2. Flame Length: Up to 8 feet.
3. Rate of Spread: Moderate to high, increasing significantly on slopes over 30 percent.
4. Spotting: Short-range spotting is common.
5. Terrain Influence: Steep slopes (30 percent or greater) increase fire spread and intensity.
6. Suppression Difficulty: Challenging for ground crews without support from engines,
dozers, or aircraft. Dozers and plows are generally effective on moderate terrain.
16 | P a g e
The following section is hereby deleted in its entirety:
303.2.3 High Intensity. High Fire Intensity Classification is identified in areas with heavy,
continuous fuel loads, such as dense forest canopies, thick understory growth, and heavy
dead/downed material. Fires in this class frequently occur on steep slopes, often exceeding 40
percent, where topography dramatically increases the rate of spread and severity. Flame lengths
can exceed 30 feet, and both short- and medium-range spotting are common, particularly in windy
conditions. Direct suppression by ground crews is typically ineffective, requiring indirect attack
strategies, such as backburns and aerial retardant drops. Fires in this class pose extreme risk to life,
property, and firefighter safety, especially in rugged or remote areas.
Key Characteristics Include:
1. Fuels: Heavy fuels, including dense forests, urban core areas with heavy fuel loads, and
canopy-dominated regions (e.g., WNH, USH, UCH fuel types).
2. Flame Length: Up to 30 feet or more.
3. Rate of Spread: Rapid, especially on slopes greater than 40 percent.
4. Spotting: Short-range spotting is common; medium-range spotting is possible under
windy conditions.
5. Terrain Influence: Slopes over 40 percent amplify intensity and spread, creating
dangerous conditions for suppression.
6. Suppression Difficulty: Direct attack by ground forces and dozers is generally ineffective.
Indirect strategies (backburning, aerial support) are often necessary. These fires present significant
danger to life, property, and responder safety.
The following section is hereby deleted in its entirety:
303.3 Applicability of Code Provisions. The requirements of this code shall apply to all parcels
located within designated Wildfire Hazard Areas and corresponding fire intensity classifications as
identified on the official maps. The level of structure hardening, defensible space, and other
mitigation measures required shall correspond to the applicable fire intensity classification—Low,
Moderate, or High as established by the board.
Structures and parcels identified with low fire intensity classification shall be constructed and
maintained in accordance with the provisions for Class 1 structure hardening and site and area
requirements.
Structures and parcels identified with moderate to high fire intensity classifications shall be
constructed and maintained in accordance with the provisions for Class 2 structure hardening and
site and area requirements.
SECTION 304 GROUND-TRUTHING
304.1 Purpose. This section establishes a process for owners or the owners authorized
representative to request a ground-truthing review of their property’s Wildfire Hazard or fire
intensity classification as identified on state or locally adopted maps. The intent is to provide
an opportunity to verify that mapping accurately reflects current, site-specific conditions.
The following section is hereby amended to read as follows:
304.2 Determination of Fire Intensity Classification Wildfire Hazard and Code Requirements.
As determined by the code official, the fire intensity classification Wildfire Hazard Area and
associated requirements shall be based on a review of the vegetative fuels on the parcel and within
17 | P a g e
300’ of the parcel boundary, including but not limited to topography, local weather patterns and fire
behavior modeling data. and in accordance with the following fire intensity classifications:
304.2.1 Low Fire Intensity Classification in accordance with Section 303.2.1
304.2.2 Moderate Fire Intensity Classification in accordance with Section 303.2.2
304.2.3 High Fire Intensity Classification in accordance with Section 303.2.3
This determination shall be made based on existing conditions or conditions that have been
established by a development plan approved by the local jurisdiction. Technical documentation shall
be submitted in support of such request by a qualified wildfire professional and in accordance with
Section 104.2.
