STAFF LIAISON UPDATE.
Deputy Town Administrator Damweber stated the Town Board approved the Workforce
and Childcare Funding Plan which would be presented to the Larimer County Board of
County Commissioners for consideration. He stated the Town would consider
contributions toward the YMCA of the Rockies to assist with filling childcare positions
which remain vacant. He stated a childcare needs assessment would be completed in
2023. He stated the Board have mentioned the need for a task force to inform the Board
on the childcare needs and other issues. The Town Board would be identifying a
spending plan for 6E funds during the 2024 Strategic Planning process.
Chair Almond stated FAB had received criticism in the past for lack of recommendations
to the Town Board and requested clarification on the process of informing the Town
Board of advisory board recommendations. She questioned how providers are informed
on funding options available through the Town. Discussion ensued regarding home-

POLICE DEPARTMENT CO-RESPONDER PROGRAM.
Kristi Capo, SummitStone Co-Responder with SummitStone and clinical mental health
provider reviewed services provided and the typical calls which they respond to. She
stated calls range from family disputes, general mental health related de-escalation, or
contact connection for resources and referrals. Services encompass all of Larimer
County and she acknowledged the difficulties individuals face in crisis who need
services which are only provided outside of the Estes Valley. She stated SummitStone
received additional funding to allow for a second co-responder in Estes Park to increase
the resource availability 7 days a week. FAB questions have been summarized: whether
SummitStone provides referrals to outside agencies including those outside of the Estes
Valley; how SummitStone coordinates services with the Estes Valley Crisis Advocates;
and if SummitStone responds to mental health related issues at the school. The FAB
stated the importance of responders being informed on available resources within the
community and they encouraged opportunities to connect with community organizations
and ways to support the Spanish speaking members.
TOWN BOARD DECISION TO SUNSET FAB - MEMBERSHIP COMMENTS.
Chair Almond provided highlights of the February 28, 2023 Town Board Study Session
FAB discussion and the discussion to sunset FAB. It was mentioned the FAB could
request the Town Board to maintain FAB or members could create a community
advocacy group and continue similar work outside of Town Board appointment.
Cindy Younglund arrived at 4:42 p.m.
FAB comments have been summarized: Concern was stated for lack of support from
the Town Board and clarity on directives for FAB; support was stated in advocacy for
families in a different way; a community group would be an opportunity to build
relationships; interest was heard to form a community group with more flexibility; new
members appointed in 2022 stated frustration in the state of the FAB not being identified
during interviews; disappointment was stated in the Town Boards decision and interest
was stated in advocating for maintaining the FAB.
Members of FAB stated the importance of fighting and supporting families, providing
resources, engaging with the Hispanic community, and focusing efforts to be most
effective.
Deputy Town Administrator Damweber stated FAB has elevated the needs of families in
the community since formation. At the time FAB was established the Town also formed
the Community Initiative Funding program which has been instrumental in forming
relationships with outside partners and identifying the needs of the community. He
encouraged FAB to consider how they can be most effective in advocating for change
and influencing policy decisions on behalf of families.
Member White left at 5:05 p.m.
Trustee Younglund commended FAB for bringing awareness to family needs and stated
opportunity exists for the high energy of members to continue serve the community in a
different setting or group.
Discussion ensued regarding FAB member interest in advocating against the sunset
decision by the Town Board or forming a community group to advocate for families.
Consensus was to continue to advocate for the needs of families in the community while
maintaining effectiveness. It was moved and seconded (Yowell/Almond) to
recommend the Town Board not sunset FAB, and it passed unanimously.
There being no further business Chair Almond adjourned the meeting at 5:36 p.m.

motion passed 2-0.
Public Comment: none
VARIANCE REQUEST TBD Raven Avenue Senior Planner Woeber
The Applicant seeks a 10-foot variance to the minimum lot width standard for the RM
Zone District in accordance with Estes Park Development Code (EPDC) Section 3.6.C. If
approved, the property will be subdivided into five lots, each 50 feet wide.
Discussion: David Emerson, director of St. Vrain Habitat for Humanity, relayed plans for
providing affordable housing in Estes Park at a 60% AMI or lower. He thanked the Board
for hearing the variance.
It was moved and seconded (Moreau/Holtzman) to approve the variance request for a
10-foot setback to the minimum lot width in accordance with the findings as
presented. The motion passed 2-0.
VARIANCE REQUEST 160 First Street Planner I Washburn
The Applicant requests approval of a variance to allow a reduced front setback of eight
and three-tenths feet (8.3’) and a reduced arterial road setback of twenty-two feet six
inches (22’-6”) in lieu of the fifteen feet (15’) and twenty-five feet (25’) respective setbacks
required in the CO (Commercial Outlying) Zoning District under Section 4.4.C.4. of the
Estes Park Development Code (EPDC). The Applicant proposes eliminating three
parking spaces in the subject area to construct a deck for outdoor seating at the El Mex-
Kal Family Restaurant.
Discussion: Member Holtzman requested removing the fourth parking space and
including a bollard. Backing out of those parking spaces is a hazard.
Mark Rismiller, the property owner, explained the reason for not using the 4th parking
space for the decking was due to Estes Park Sanitation concerns with accessing the
clean-out sewer lines. He will check with EPSD on the placement of the bollard.
It was moved and seconded (Moreau/Holtzman) to approve the variance request for
reduced front setback and reduced arterial road setback for the subject property
addressed as 160 1st Street in the Town of Estes Park, with findings as outlined in the
staff report with the addition of installing a bollard to keep people from parking in the fourth
parking spot. The motion passed 2-0.

ACTION ITEMS
Stanley Home Museum Amendment to S2 Special Review
Senior Planner Woeber reviewed the staff report. The original Special Review for the Cultural
Institution (Stanley Home Museum and Education Center) was approved by the Town Board on
August 28, 2018. Woeber described the amendments proposed to five of the thirteen previous
Conditions of Approval. The original conditions will remain unchanged.
Condition No. 1: The applicant proposes allowing two tour groups of up to 12 people (the
maximum currently allowed) to be on the property at the same time, but with more overlap than
what is currently allowed. Currently, only “brief and incidental overlap” is permitted. The applicant
notes 99% of tours have six or fewer people.
Condition No. 2: Sunday hours are 12:30 p.m. to 4:45 p.m. The applicant proposes amending
the Sunday hours to 9:45 a.m. to 4:45 p.m. Mondays are closed under current Condition #2
unless it is a holiday. The applicant proposes expanding this to Mondays, which are a holiday or
if a Special Event is scheduled.
Condition No. 3: Special Events are a key component of the Stanley Home operation. Currently,
there is a limit of two Special Events per month. The applicant proposes expanding this to four
per month, with eight allowed during December. Outdoor Special Events are also proposed, up
to one per month with a limit of four during a calendar year.
Condition No. 10: Currently, tour attendees must use a shuttle to visit the Stanley Home from May
1 to October 31. The applicant proposes allowing attendees to park on-site year-round. There
are eleven existing parking spaces, with five additional spaces proposed. Shuttle service would
continue to be used for Special Events.
Page 21
Planning Commission – January 17, 2023 – Page 2
Condition No. 11: The eleven existing parking spaces are designated for employee parking, in
addition to one ADA Handicap space, from May 1 to October 31. The applicant proposes allowing
these and the five proposed spaces to be used by tour attendees year-round.
DISCUSSION:
David Batey, the Historic Stanley Home Foundation Chair, was available for
questions. Regarding the Conservation Easement requirement, there was a requirement to
initiate this, but it was determined it was not feasible. Vice-Chair Heiser suggested removing this
item from the conditions. The increased number of tours and parking was reviewed and deemed
appropriate. Tour times will not overlap. Outdoor special events are still required to conclude by
8:00 p.m.
Public Comment: none
It was moved and seconded (Heiser/Hanson) to forward a recommendation of approval
to the Town Board of Trustees of the Special Review Amendment with the findings and
condition of approval recommended by Staff, suggesting that Staff look at all conditions
of approval which are still relevant. The motion passed 4-0.
REPORTS:
The Comprehensive Plan is complete and accepted by all bodies. Hard copies are
available if wanted.

New planner Kara Washam and new Commissioner Chris Pawson were introduced.
Consultants Mike Scholl and Matt Ashby from Ayres gave a report on medium-density
housing, or “The Missing Middle.” This has been an ongoing discussion, beginning in
August of 2021. It has been delayed due to the Comprehensive Plan rewrite and the
new Housing Needs Assessment (HNA). The new HNA suggests 2,700+ housing units
are needed in the Estes Valley. Medium density is the blending of single-family housing
and large, high-density apartment complexes. This is in contrast to the traditional lots or
units-per-acre practice. The community decides the definition of “middle” and
establishes the rules.
Benefits of medium-density housing options:
Workforce
Different stages of life
Support for transit options
Walkability
Improved neighborhood character
Opportunity for more attainable housing
Diverse price points
Multi-step process:
New zone district
Rezone applications
platting/site planning
Permitting
Page 23
Planning Commission Study Session January 17, 2023 – Page 2
There are at least two options on how to integrate current neighborhoods into higher density:
-Missing Middle Open-higher scale, walkable/transit, more urban design,
-Missing Middle Limited-less dense, lower scale, natural focal point, sensitive to existing
development
The process is about customization, rules you must follow, guidelines for consideration and
adding details of how to make it work.
-Determine where zoning designation is appropriate in the geographic component
-Do areas correlate to all or a portion of the missing middle?
-What checks and balances are necessary for each category?
-Important to connect this process to the Comprehensive Plan
Director Garner stated that diversity is needed at all levels: housing, income, and age.
The accessible, easy places to build are no longer available, so we have to look deeper
and get creative.
This topic will be continued at the February 21 Study Session.

Chair Comstock called the meeting to order at 12:00 p.m. There were four members of
the community present.
Housing Authority Executive Director Scott Moulton gave a presentation on the recently
completed Housing Needs Assessment, focusing on some of the highlights. See the
meeting recoding for detailed conversation. PowerPoint presentation attached.
1.Key Findings: age profile, job projections, housing stock (occasional use
approximately 40%), price increases.
2.Data Analysis: The above findings lead to the “housing gap analysis,” with an
acute need at the lower income levels. Right now, the total existing unit need is
1,220. The housing authority has over 1,000 people on a waiting list.
3.Strategic Plan Overview: preserve current housing stock and alter its use, not
necessarily build hundreds of new units. This can be done through property
acquisition, deed restriction buy-down, renovation and rehab, among many other
options. Development Code updates to increase density and Development
Project requirements to house employees are also needed. Using the estimated
$5 million 6E funds will open up many opportunities.
Discussion: Housing Authority must use these implementation plans to make housing
available. What should be allowed as a “use by right” needs to be included in the
Development Plan rewrite. The Planning Commission can focus on gauging projects
that come across their path by keeping the future Code in mind. Some 6E funding
could be used for the Code rewrite. Defining workforce, attainable, and affordable
housing would be helpful.
The Missing Middle discussion will be brought back to the Commission at a later date.

Chair Comstock started the meeting at 10:30 a.m. There were five members of the
community present.
Planner I Washam gave an update to the Commission on Community Planning for
Wildfires (CPAW). The CPAW program was paused due to staff changes and the
completion of the Comprehensive Plan. The Memorandum of Understanding has been
renewed until December 31, 2023. CPAW recommendations are intended to
complement the other wildfire studies that have been done. Most of the changes can
be integrated into the Development Code update, with a high priority on landscaping
standards and plant suggestions. Chair Comstock noted that enforcement would be
necessary for the implementation.
Heiser asked that staff inform developers of this endeavor. There is guidance in the
code that states that if you are accomplishing the same goals, you don't have to meet
the exact standards, leaving some flexibility in the Landscape Code and
balancing development standards.
Ayres Associate Mike Scholl reviewed the most current findings regarding the Missing
Middle code amendment. Per the Housing Needs Assessment and Strategic Plan,
creating desirable and compatible neighborhoods is vital to the Missing Middle goal.
The approach is to amend Chapter 9, Planned Unit Developments (PUDs) and establish
two new zoning districts: Mixed Neighborhood Residential and Neighborhood Village.
Due to its uniqueness, the standard code paradigm won't work in Estes Park.
Purpose: to provide a compatible range of housing types within neighborhoods and
projects based on plans that promote well-designed communities and integrate with
surrounding development.
Page 27
Planning Commission Study Session March 21, 2023 –Page 2
Per Attorney Kramer, creating standards to help say Yes or No to a project is needed,
with defined criteria and a multi-step process.
Considerable discussion on PUDs and time frames was had. (see recording
https://www.youtube.com/watch?v=l3ewUxmVIxU).
Questions to consider for the subsequent discussion were given:
Lot size minimums?
Open Space types?
Internal Circulation regarding street standards?
Home sites related to open spaces?
This topic will be continued at the April 16 Study Session.
There being no further business, Chair Comstock adjourned the meeting at 12:10 p.m.

RE: Correcting the Appointment of Richard Dowling to the Estes Park Board of
Appeals for a term expiring May 1, 2025.
(Mark all that apply)
PUBLIC HEARING ORDINANCE LAND USE
CONTRACT/AGREEMENT RESOLUTION OTHER Appointment
QUASI-JUDICIAL YES NO
Objective:
To consider a correction to the Appointment of Richard Dowling to the Estes Park Board
of Appeals
Present Situation:
The term of Richard Dowling is set to expire May 1, 2023. As the Clerk’s Office prepared
for interviews to fill this appointment and an additional vacancy, it was determined that
Richard’s original appointment was for a partial term expiring May 1, 2023, when it should
have been for a full five-year term expiring May 1, 2025.
Proposal:
After consulting with the interview committee of Trustees Hazelton and Younglund, and
confirming Richard Dowling’s continued interest in serving, the correction to the
appointment is being submitted to the Board for consideration.
Advantages:
Provides continuity on the Estes Park Board of Appeals and would bring the appointment
in-line with the bylaws.
Disadvantages:
If the correction is not made, the position would become vacant until interviews could be
conducted.
Action Recommended:
Correct the appointment of Richard Dowling to a five-year term expiring May 1, 2025.
Finance/Resource Impact:
None.

Board of Trustees
From: Dan Kramer, Town Attorney
Date: April 25, 2023
RE: Resolution 45-23 Opposing Colorado Senate Bill 23-213
(Mark all that apply)
PUBLIC HEARING ORDINANCE LAND USE
CONTRACT/AGREEMENT RESOLUTION OTHER______________
QUASI-JUDICIAL YES NO
Objective:
Formalize a position of the Town on Colorado Senate Bill 23-213, regarding Land Use.
Present Situation:
A bill has been introduced in the Colorado Senate that would dramatically change the
relationship between the State and local governments on matters of land use and
zoning. The bill was passed out of the Senate Local Government & Housing Committee
on April 19. The committee also approved a number of amendments to the bill for
consideration by the whole Senate, although no amendment has yet passed which
would significantly alter the effect of the bill on Estes Park.
Staff have begun to advocate against the bill before the members of the General
Assembly, as directed by the Board at its April 11, 2023 study session. This work has
been in concert with the ongoing efforts of the Colorado Municipal League, the Colorado
Association of Ski Towns, and municipalities across the state.
Proposal:
At the April 11 study session, the Board directed staff to bring back a resolution to
formalize the Town’s opposition to the bill. Such a resolution is included for the Board’s
consideration.
Advantages:
State legislators would be further apprised of the Board’s continued opposition to the
bill, and the formal resolution of the Board may have a greater impact than staff’s
advocacy alone.
Disadvantages:
None identified. The bill would not provide any additional local authority on land use
matters. Opposition to a bill is a Board policy decision.
Page 43
Action Recommended:
If the Board wishes to oppose the bill, I recommend the Board pass the resolution.
Finance/Resource Impact:
Minimal to none. Staff is already advocating on the bill.
Level of Public Interest
Interest in the bill is high.
Sample Motion:
I move for the approval/denial of Resolution 45-23.
Attachments:
1. Resolution 45-23.
2.Presentation slides (beginning p. 13) on SB 23-213 from April 11, 2023 Study

RESOLUTION 45-23
A RESOLUTION OPPOSING SENATE BILL 23-213
WHEREAS, Senate Bill 23-213 on Land Use has been introduced at the Colorado
General Assembly; and
WHEREAS, the bill would supersede many provisions of the Estes Park
Development Code regarding accessory dwelling units and occupancy limitations, which
provisions were carefully considered and underwent substantial public involvement; and
WHEREAS, the bill would require the Town to allow development of accessory
dwelling units in ways that do not fit the character of the neighborhoods of Estes Park,
and would not allow the Town to condition these approvals on the units being reserved
for workforce or attainable housing; and
WHEREAS, land use and zoning are matters of local concern, and on these
matters the State should continue the longstanding tradition of allowing local democratic
processes to reach the best outcomes for local communities.
NOW, THEREFORE, BE IT RESOLVED BY THE BOARD OF TRUSTEES OF
THE TOWN OF ESTES PARK, COLORADO:
The Town of Estes Park opposes the adoption of Senate Bill 23-213 and urges the
members of the General Assembly to reject it.

RE: Setting the Public Hearing For Ordinance 04-23 Amending Chapter 14.12
Of The Estes Park Municipal Code To Adopt The 2021 Editions Of
International Codes, Including The International Building, Residential,
Existing Building, Fuel Gas, Mechanical, Plumbing, Property Maintenance,
Energy Conservation, And Swimming Pool And Spa Codes, With
Amendments
PUBLIC HEARING ORDINANCE LAND USE
CONTRACT/AGREEMENT RESOLUTION OTHER______________
QUASI-JUDICIAL YES NO
Objective:
Set the public hearing to consider Ordinance 04-23 for the 2021 International Building
Codes with local amendments.
Present Situation:
Staff from Community Development has been working with the Building Advisory
Committee (BAC) since 2021 to review the 2021 series of International Codes in order
to clarify questions about the codes, the costs of implementing the most recent code
cycle, and to determine which code cycle to recommend to the Board for adoption.
Proposal:
Staff recommends adoption of the 2021 International Building Codes with amendments,
with the with the Ordinance effective 30 days after publication and the codes
coming into effect January 1, 2024. As amended, the 2021 International Building Code
includes, by reference, the following codes in their entirety:
•International Existing Building Code
•International Fuel Gas Code
•International Mechanical Code
•International Plumbing Code
Memo COMMUNITY DEVELOPMENT
Page 47
•International Property Maintenance Code
•International Energy Conservation Code
The International Pool and Spa Code and the International Residential Code are
adopted separately and not as a part of the IBC.
Currently, the draft IRC would require all new single-family homes, two-family homes,
duplexes, and townhomes to have sprinklers installed throughout the residence. Should
the Board decide to revise this requirement, staff can make the amendment prior to the
public hearing on May 23rd.
Additionally, the Board has the option to adopt either the following optional appendices
in conjunction with the International Energy Conservation Code, or the Colorado Model
Electric Ready and Solar Ready Code (attached for the Board’s review), currently in
final draft form:
•Appendix RB: Solar-Ready Provisions- Detached One- and Two-Family
Dwellings and Townhouses (Although Appendix RB does not require solar
systems to be installed for a building, it does require the space(s) for installing
such systems, providing pathways for connections and requiring adequate
structural capacity of roof systems to support the systems)
•Appendix CB: Solar-Ready Zone- Commercial (Intended to encourage the
installation of renewable energy systems by preparing buildings for the future
installation of solar energy equipment, piping and wiring)
•Appendix RC: Zero Energy Residential Building Provisions (Provides
requirements for residential buildings intended to result in net zero energy
consumption over the course of a year)
•Appendix CC: Zero Energy Commercial Building Provisions (Intended to
supplement the International Energy Conservation Code and require renewable
energy systems of adequate capacity to achieve net zero carbon)
Staff recommends the Board adopt either Appendices RB and CB, or the Colorado
Model Electric Ready and Solar Ready Code, due to significant overlap of regulations.
Staff does not recommend adopting, and has not included in the draft ordinance for
adoption, Appendices RC and CC, as we understand only one Colorado municipality
has adopted either of the two, for various reasons. Should the Board adopt the 2021
IECC, staff recommends further review and discussion of Appendices RC and CC,
which can be adopted later with no detrimental impact on the cumulative 2021 IECC
elements so long as the Town also adopts the Colorado model electric ready and solar
ready code at this time.
For consideration to amend and adopt the 2021 International Building Codes, staff
presents the following options to the Board of Trustees and the Town of Estes Park.
Each set of Codes listed above would be adopted by reference, and require additional
public notice before the public hearing on May 23. Copies of each of the Codes are
Page 48
available in the Town Clerk’s office from 8:00 am-5:00 pm, Monday through Friday until
May 23.
Advantages:
Adoption of the 2021 International Building Codes keeps the Town up to date on
industry standards, new technologies and materials, recent studies, and other
jurisdictions, including Larimer County.
The 2021 Codes also provide safeguards and establish minimum safety standards for
all aspects of building construction (structural, plumbing, electrical, gas, mechanical,
and energy).
Disadvantages:
While the Town has typically adopted new building codes on a six-year cycle, there is
an expected learning curve as contractors and designers in the industry acclimate to
new and/or revised requirements.
Action Recommended: The Board cannot approve the adoption of any of the five
options below on April 25th, but can direct staff to revise the Ordinance with any
of the following options for final adoption in May.
Option One: Approve adoption of the 2021 IBC and related codes with amendments
presented at the Town Board meeting on May 23, 2023, including optional Energy Code
Appendices CB and RB.
Option Two: Approve adoption of the 2021 IBC and related codes with amendments
presented at the Town Board meeting on May 23, 2023, excluding optional Energy
Code Appendices CB and RB.
Option Three: Approve adoption of the 2021 IBC and related codes with amendments
presented at the Town Board meeting on May 23, 2023, including the Colorado Model
Electric Ready and Solar Ready Code, and schedule a study session to discuss the
possibility of adding Appendices RC and CC, as well as electric-preferred provisions
presented by SWEEP at a later date.
Option Four: Possible Alternative as the Legislative Authority
The Board of Trustees may postpone adoption of the 2021 International Codes or direct
staff to revise any portions of the codes.
The Community Development Department recommends Option Three if the Board
wishes to regulate above and beyond what is required at this time. Since its
development, we understand that the state model code has largely supplanted the 2021
Energy Code appendices as a method of exceeding the 2021 codes.

AMENDMENTS FOR 2021 IECC ADOPTION
INTERNATIONAL ENERGY CONSERVATION CODE
Section xx. The International Energy Conservation Code, 2021 Edition, (the "IECC"), as published
by the International Code Council, 500 New Jersey Avenue, NW, 6th Floor, Washington, DC 20001, a
copy of which is on file and open for inspection in the office of the Town clerk, is hereby adopted by
reference subject to the additions, amendments, and appendices set forth herein. The IECC includes
appendices CB and RB by the International Code Council, and new appendices CD and RD as set forth
below. The subject matter of the IECC includes the design of energy-efficient and high-performance
buildings and related energy uses including mechanical, lighting, power systems, and electric vehicle
infrastructure for the purpose of protecting the public health, safety and welfare. The 2021 IECC, as
amended in this Article, shall apply to all property within the Town of Estes Park.
The IECC is amended as follows:
COMMERCIAL
1.Section C101.1 Title is retained in its entirety with the following amendments:
C101.1 Title. This code shall be known as the International Energy Conservation Code of the
Town of Estes Park and shall be cited as such. It is referred to herein as “this code” or “the
IECC.”
This ensures fuel source, electric-ready, solar-ready, and EV-ready are shown on the
construction documents. Since some of these are new elements, this also helps with compliance.
2.Section C103.2 Information on construction documents, is amended by modifying item 6 and
adding items 14, 15, and 16 as follows:
6.Mechanical and service water heating systems and equipment types, sizes, fuel source,
and efficiencies.
14.Details of additional electric infrastructure, including branch circuits, conduit, or pre-
wiring, and panel capacity in compliance with the provisions of this code.
15. Location of pathways for routing of raceways or cable from the solar ready zone to the
electrical service panel.
16. Location of designated EVSE spaces, EV-Ready spaces, and EV-Capable spaces in
parking facilities.
This adds the electric-ready infrastructure to inspection.
3. Section C105.2.5 Electrical system is amended to read:
C105.2.5 Electrical system. Inspection shall verify lighting system controls, components, and
meters, and additional electric infrastructure, as required by the code, approved plans and
specifications.
Attachment 5
Page 128Page 133
This adds definitions to accommodate all-electric building.
4. Section C202 GENERAL DEFINITIONS is amended to add or revise the following definitions
in alphabetical order:
ALL-ELECTRIC BUILDING. A building and building site that contains no combustion
equipment, or plumbing for combustion equipment, and that uses heat pump technology as the
primary supply for heating, cooling, and service water heating loads.
COMBUSTION EQUIPMENT: Any equipment or appliances used for space heating, cooling,
water heating (including pools and spas), cooking, clothes drying or lighting that uses natural gas,
propane, other fuel gas, or fuel oil.
MIXED-FUEL BUILDING. A building and building site that contains combustion equipment, or
plumbing for combustion equipment, for space heating, cooling, water heating (including pools
and spas), cooking, or clothes drying.
This adds electric-ready and electric-preferred for commercial buildings selecting the Total
Building Performance path.
5. Section C401.2.1 International Energy Conservation Code, item 2, is amended to read as follows:
2. Total Building Performance. The Total Building Performance option requires compliance
with Section C407 and, for mixed fuel buildings, Section C405.13 and 10 credits from Tables
C406.1(1) through C406.1(5).
This adds electric-ready and electric-preferred for commercial buildings selecting ASHRAE 90.1.
6. Section C401.2.2 ASHRAE 90.1 is amended to read as follows:
C401.2.2 ASHRAE 90.1. Commercial buildings shall comply with the requirements of
ANSI/ASHRAE/IESNA 90.1 and, for mixed fuel buildings, Section C405.13 and 10 credits from
Tables C406.1(1) through C406.1(5).
This ensures that renewable energy used to meet the exemption is not also double-counted
towards compliance with C406.
7. C404.2.1 High input service water-heating systems, item 1 under exceptions, is amended to read
as follows:
1. Where not less than 50 percent of the annual service water heating requirement is
provided by on-site renewable energy or site-recovered energy not including any capacity
used for compliance with Section C406 of this code, the minimum thermal efficiency
requirements of this section shall not apply.
This is part of electric-ready. It ensures sufficient physical space for future electric water heating
systems. It only applies to water heaters with a clear path to electrification presently and
exempts systems that don’t.
8. Section C404.10 is added as follows:
C404.10 Water heating equipment location. Water heaters with combustion equipment shall be
located in a space with the following characteristics:
1. Minimum dimensions of 3 feet by 3 feet by 7 feet high.
Page 129Page 134
2. Minimum volume of 760 cubic feet, or the equivalent of one 16-inch by 24-inch grill to a
heated space and one 8-inch duct of no more than 10 feet in length for cool exhaust air.
3. Contains a condensate drain that is no more than 2 inches higher than the base of the
installed water heater and allows natural draining without pump assistance, installed
within 3 feet of the water heater.
Exceptions:
1. Instantaneous water heaters located within 10 feet of the point of use.
2. Water heats with an input capacity of more than 300,000 Btu/h.
This disallows gas-powered lighting. Gas lighting is rarely used anymore, but this adds assurance
that it can’t be.
9. Section C405.5.3 Gas lighting is amended to read as follows:
Section C405.5.3. Gas lighting. Gas fired lighting appliances shall not be equipped with
continuously burning pilot ignition systems are not permitted.
Adding a category for monitoring EV charging separately allows the building load to be measured
independently from this non-building load. This will be critical with the wider adoption of
Building Performance Standards or other existing building energy use policies as it will allow EV
charging to be easily excluded from the building loads for the purposes of regulating actual
energy use in buildings. (Approved for the 2024 IECC by the full Commercial Consensus
Committee.)
10. Table C405.12.2 ENERGY USE CATEGORIES is amended to add a new line at the end:
Electric vehicle charging Electric vehicle charging loads.
This adds electric-ready wiring for combustion equipment.
11. A new Section C405.13 is added to read as follows:
C405.13 Additional electric infrastructure. All combustion equipment shall be provided with a
junction box that is connected to an electrical panel by continuous raceways that meet the
following requirements:
1. The junction box, raceway, and bus bar in the electric panel and conductors serving the
electric panel shall be sized to accommodate electric equipment sized to serve the same
load as the combustion equipment.
2. The panel shall have reserved physical space for a three-pole circuit breaker.
3. The junction box and electrical panel directory entry for the dedicated circuit breaker
space shall have labels stating “For future electric equipment.”
4. The junction box shall allow for the electric equipment to be installed within the same
place of the combustion equipment that it replaces.
Exceptions:
1. Warm air furnaces serving spaces that also have space cooling.
2. Water heating equipment with an input capacity more than 300,000 Btu/h
3. Industrial, manufacturing, laboratory, and high hazard occupancy combustion
equipment.
Page 130Page 135
This is the electric-preferred section. To encourage electrification of buildings while allowing for
mixed-fuel construction, mixed fuel buildings are required to achieve more efficiency credits (20
instead of 10).
12. Section C406.1 Additional energy efficiency credit requirements, first sentence, is amended to
read as follows with the other parts of the paragraph and section to remain:
C406.1 Additional energy efficiency credit requirements. New all-electric buildings shall
achieve a total of 10 credits and new mixed-fuel buildings shall achieve a total of 20 credits from
Tables C406.1(1) through C406.1(5) where the table is selected based on the use group of the
building and from credit calculations as specified in relevant subsections of C406.
Continuing with electric preferred, this fixes a problem where fossil fuel water heaters were
given more credits than high-efficiency electric. (This problem is also fixed in the 2024 IECC by
the Commercial Consensus Committee.)
13. TABLE C406.1(2) ADDITIONAL ENERGY EFFICIENCY CREDITS FOR GROUP R AND I
OCCUPANCIES is retained in its entirety, except Sections C406.7.3 and C406.7.4 in Climate

propane, other fuel gas, or fuel oil.
MIXED-FUEL BUILDING. A building and building site that contains combustion equipment, or
plumbing for combustion equipment, for space heating, cooling, water heating (including pools
and spas), cooking, or clothes drying.
This encourages electrification and more evenly weighs the impact of the additional efficiency
credits by requiring a mixed-fuel home to select three packages whereas an all-electric home
selects one. Of the three packages required for the mixed-fuel home, one must address the
envelope (improved envelope or reduced infiltration plus better ventilation) while the remaining
two impact HVAC (better equipment or more efficient ducts) and water-heating (better
equipment) requirements.
22. Section R401.2.5 Additional energy efficiency is amended as follows:
R401.2.5 Additional energy efficiency. This section establishes additional requirements
applicable to all compliance approaches to achieve additional energy efficiency.

Section R408.2 shall be installed without including such measures in the
proposed design under Section R405.
2.2. For mixed-fuel buildings, three of the additional efficiency packages shall be
installed, at least one of which addresses the envelope, without including such
measures in the proposed design under Section R405.
2.3. For all-electric buildings, the proposed design of the building under Section
R405.3 shall have an annual energy cost that is less than or equal to 95 percent of
the annual energy cost of the standard reference design.
2.4. For mixed-fuel buildings, the proposed design of the building under Section
R405.3 shall have an annual energy cost that is less than or equal to 80 percent of
the annual energy cost of the standard reference design.
3. For buildings complying with the Energy Rating Index alternative Section R401.2.3, the
Energy Rating Index value shall be at least 5 percent less than the Energy Rating Index
target specified in Table R406.5.
The options selected for compliance shall be identified in the certificate required by Section
R401.3.
This adds fuel sources, solar-ready, and electric-ready information to the certificate.
23. Section R401.3 Certificate, item 4, is amended and new items 8, 9, and 10 are added as follows:
Page 137Page 142

International Energy Conservation Code
About I-Codes: Building codes improve the quality of construction of the built environment
and thereby promote the health, safety, resiliency, affordability, sustainability, and general
welfare of our communities. Building codes set a bare minimum construction quality that local
officials deem necessary and that consumers expect. Most jurisdictions across the country
adopt model building codes published by the International Code Council, and these are
updated every three years in an extensive process involving builders, trades, architects,
manufacturers and suppliers, low-income advocates, and, crucially, local building officials who
are ultimately responsible for enforcing the codes. These codes are then adopted at local
level. The 2021 codes are the most recent edition.
About the 2021 International Energy Conservation Code (IECC): After two previous cycles of
stagnant efficiency, building officials voted overwhelmingly in favor of provisions in the latest
IECC to strengthen energy efficiency. Overall, the 2021 IECC reduces energy by 8-9% (and
reduces energy bills by 8-9%) compared to the previous 2018 IECC. The 2021 also includes
language clean-up and clarifications, and an expanded focus on flexibility and options. Most
of the changes "tighten up" provisions already in the code. Key changes for residential new
construction include a better "thermal envelope" (e.g. walls, insulation, windows, doors, etc.),
windows that take into account "solar heat gain" in climate zone 5B (the climate zone for the
front range of Colorado), changes to duct testing, and increased use of lighting controls. On
the commercial side, key changes include air barrier commissioning (i.e. testing and
verification of the layer in walls that keeps outside air out and clean, conditioned inside air in),
more efficient mechanical systems, technology for energy monitoring in larger buildings so
that building operators can better measure and track their building's energy use, and increased
options for additional energy efficiency "points."
Jurisdictions with the 2021 IECC: Arapahoe County, Aurora, Carbondale, Crested Butte,
Denver, Dolores, Erie, Fort Collins, Golden, Larimer County, Littleton, Longmont, Louisville,
Parker, Superior, and Vail. At least 66 other jurisdictions covering 70% of Colorado's
population have announced plans to adopt the 2021 IECC in the next year.
New Colorado Law (2022): The Colorado legislature passed a new bipartisan law that updates
minimum energy code requirements. Jurisdictions must adopt at least the 2021 IECC, along
with EV-ready, PV-ready, and electric-ready, when updating any other building codes
between July 1, 2023 and July 1, 2026. After that date, jurisdictions must adopt at least a low-
energy and carbon code. A new Energy Code Board will identify code language for the EV-
ready, PV-ready, electric-ready, and low energy and carbon code, and jurisdictions can choose
to adopt that code language, something equivalent, or something stronger.

Cost Discussion: An extensive analysis from the Pacific Northwest National Labs (PNNL, the
entity charged by the U.S. Congress to perform energy code cost-effectiveness studies)
calculates that the increased first cost per household is $3,376 for the 2021 IECC versus the
2015 IECC in Climate Zone 5B (as of Dec. 2021). PNNL's analysis is considered the most
credible compared to other estimates because of PNNL's long-standing peer-reviewed
methodology, and its absence of profit motive or conflict of interest. The majority of the first
cost increase compared to the 2015 IECC is an increase in insulation levels. (Cost data is
roughly similar between the 2015 and 2018 IECC, since the efficiency levels were similar.)
Prepared For: DOLA Code Cohort for Northwestern Metro / Boulder County
Date Updated: January 8, 2023
Mild/Medium/Aggressive Rating: Mild. The 2021 IECC is the minimum energy code required
by the state of Colorado and even before the state law, jurisdictions covering half of
Colorado's population had already announced plans to adopt it. As such, "mild" also includes
EV-ready, PV-ready, and electric-ready as required by Colorado law. A "medium" rating would
include a higher degree of electric transition – for instance, allowing a choice of either all-
electric or mixed fuel new construction but requiring mixed fuel homes and buildings to
pursue additional energy efficiency to make up for the extra emissions from fossil gas use
onsite. An “aggressive” rating would include either all-electric requirements, the zero energy
appendices, or both.
Other studies of incremental upfront costs to builders for the 2021 IECC (not including local,
state, utility, or federal incentives):
ICF International: $3,651-$4,809
PNNL for Louisville using NAHB 19% inflation adder and larger house size: $5,118
City of Louisville (via Group 14) survey of two local builders: $6,450
Diverge Homes (high-end efficient homes in Marshall Fire area: $8,000
NAHB (via Home Innovation Research Lab): $9,435-$11,900 (note: ICF study found HIRL
study used incorrect economic assumptions)
Page 174Page 179
Solar-Ready
About: Solar-Ready appendices (RB for residential and CB for commercial) are officially
prepared by the International Code Council as “add-on” to the IECC. They prepare homes and
buildings for the future installation of solar by requiring conduit, space on the electrical panel,
space reserved on the roof free from obstructions and shady objects, adequate roof structural
capacity, notation on construction documentation, and a permanent certificate. Shady roofs
are exempted. The current appendices only include multifamily buildings 4-5 stories tall, so
an amendment is needed to include all multifamily buildings – a provision we call “expanded
solar-ready”.
Cost Discussion: Upfront costs are minimal (<$200). Cost savings include avoiding the need
to tear up walls, redo wiring, and potentially upgrade an electrical panel. They also avoid the
situation where roof penetrations for attic vents, etc. are poorly placed in a way that prevents
future solar.
Jurisdictions with Solar-Ready: Avon, Boulder, Boulder County, Breckenridge,* Carbondale,
Craig, Crested Butte, Denver, Fort Collins, Frisco,* Golden, Lafayette, Louisville, Superior, Vail,
and Wheat Ridge. Others considering or in the process of adopting it, besides Code Cohort
communities, include Eagle County (*via Summit County sustainability program). Note: a new
2022 Colorado law requires all upcoming IECC adoptions to include solar-ready provisions
equivalent to or better than a version to be identified by the state's Energy Code Board. We
highly anticipate Appendices RB and CB with the multifamily fix will meet the law.
Mild/Medium/Aggressive Rating: Mild. A “medium” rating would require solar to actually be
installed on some buildings for part of the energy load, plus a residential solar access law. An
“aggressive” rating would require solar installed on all buildings for all of the energy load, a
residential solar access law, and a retrofit policy.

EV-Ready
About: Electric Vehicle Ready (EV-Ready) appendices prepare homes and buildings for the
current transition to electric vehicles. These appendices recognize that the vast majority of all
electric vehicle charging will occur at home, with some charging infrastructure needed at work
or around town. New single family homes will require one EV-ready space, and new multifamily
and commercial buildings will require a percentage of EV-capable, EV-ready, and EV-installed
spaces depending on the building type and use.
These percentages align with levels recently approved by Denver's code committee, and are
less than the percentages adopted in some other jurisdictions (Superior, for instance).
Multifamily percentages were reduced to ease the cost impact to new housing, and commercial
building percentages were reduced to account for charging behavior based on building type.
Note: EV-ready is especially important for multifamily buildings, for equity reasons, since
renters can't retrofit their parking lot or garage to install a 240-volt outlet on their own.
(In I-code terminology, Group A is Assembly, B is Business, E is Education, F is Factory & Industrial, I is Institutional, M is Mercantile, R-1 is transient residential, R-2 is apartments and other non-transient residential, R-3 and R-4 are small group homes including halfway houses, rehab centers, care facilities, etc., and S is Storage.)
Prepared for the DOLA Code Cohort of Northwest Metro Area / Boulder County
Page 176Page 181
Market Discussion: EVs comprised 9% of new vehicle sales in Colorado in Q1 2022, and
dealers continue to have long waitlists, especially with the recent rises in gas prices. All major
auto brands have announced plans to shift the majority of their fleets to EVs by the mid-
2030s or sooner. Newer models have ranges of well over 300 miles. Besides the reduced
environmental impact, buyers like the faster acceleration, the low maintenance, the safety
ratings, and the convenience of avoiding trips to the gas station.
Cost Discussion: One EV-ready space for a single-family home averages about $325-$400
at the time of construction. Federal and Xcel Energy rebates are available. Retrofitting even
just the wiring later can run $481-$1,493 per space (depending on the distance from the
panel to the garage) plus potential costs to upgrade the electrical panel. For commercial and
multifamily, costs can run $300 for EV-capable, $1,300 for EV-ready, and $2,500 for EV-
Installed per space. Federal, Colorado, and Xcel Energy rebates are available. Retrofits done
later can cost several times more, and may include the need to tear up and rebuild walls (and
in the case of commercial and multifamily, parking lots and landscaping), redo wiring, and
upgrade the electrical panel.
Climate Impact: It depends on adoption by homeowners, but for an average-sized
household, a new EV in Colorado reduces CO2e 8,175 pounds per year compared to new gas
car (a 63% reduction), as of 2022. The CO2e reductions improve over time as Xcel's grid adds
increasing levels of renewables.
Jurisdictions with EV-Ready: Aspen, Avon, Boulder, Boulder County, Breckenridge,
Broomfield, Crested Butte, Carbondale, Denver, Dillon, Durango, Eagle County, Fort Collins,
Frisco, Golden, Lafayette, Lakewood, Larimer County, Louisville, Longmont, Pueblo County,
Steamboat, Summit County, Superior, and Vail, Others in the Code Cohort communities are
also planning to adopt it. Note: a new 2022 Colorado law requires all upcoming IECC
adoptions to include EV-ready provisions equivalent to or better than a version to be
identified by the state's Energy Code Board. We highly anticipate these amendments will
meet the new law.
Mild/Medium/Aggressive Rating: Medium. A “mild” rating would have lower percentages for
commercial and multifamily. An "aggressive" rating would require every space in multifamily
to have some level of infrastructure, plus a policy for renovations.

Electric-Readyand Electric-Preferred
About: Electric-ready amendments prepare homes and buildings for the choice between
electric and gas equipment and appliances by ensuring they have the wiring and panel
capacity available for future electric equipment (and enough physical space, in the case of
water heaters). Electric-preferred amendments, the next step, still allow new construction to
be either all-electric or "mixed fuel" (e.g. natural gas) but mixed fuel homes and buildings
require extra efficiency to make up for extra emissions.
Code Amendment Specifics: In particular, the residential amendments in the prescriptive
path require mixed fuel homes to select three "additional efficiency packages" instead of one.
Mixed fuel homes choosing the "Total Building Performance" pathway would similarly choose
three additional efficiency packages instead of one, or have annual energy costs less than or
equal to 80% of the standard reference design instead of 95%. Mixed fuel homes choosing
the "Energy Rating Index" (ERI) pathway would seek a score of 52 instead of 55.* For
commercial buildings, mixed fuel buildings would choose extra efficiency options totaling an
extra 10 points. The amendment also fixes two places in the commercial code where gas
systems were given more points than electric.
Market Developments: Air source heat pumps have been commonplace in other parts of the
country, and are now making inroads in Colorado thanks to rapid technological developments
that allow "cold climate" heat pumps to supply heat even when outdoor temps fall to -22F.
Other configurations are possible as well, such as a non-cold-climate heat pump plus extra
"strip heat" that can kick in for extra cold times. (This configuration is cheaper upfront but
more expensive to run in extra cold temperatures.) For water heating, heat pump water
heaters are an easy replacement for a typical gas or electric hot water storage tank. Finally, on
the cooking side, some homeowners may express a preference for gas, but induction stoves
are proving their mettle with twice-as-fast boil times, more finely-tunable controls, safety
protections (e.g. the ability to touch the burner and not get burned) and the near-elimination
of harmful air pollutants that lead to increased asthma rates and other respiratory distress.
Note that reliability of electric systems during a power outage is the same as for gas systems,
since gas systems require electricity to run as well.
Cost Discussion: Upfront costs depend highly on the configuration selected by the builder.
All-electric homes, depending on supply chain availability and builder/contractor familiarity,
can be built at no additional cost compared to mixed fuel [1]. Although the upfront costs of an
air source heat pump and heat pump water heater are typically more than gas equivalents,
the big savings come from avoiding the gas connection and gas piping costs to and within the
home or building, and state and utility rebates offset the cost as well. Separate market
transformation efforts are underway to train builders and contractors for the transition to all-
electric equipment, and the familiarity and economies of scale are expected to bring total
costs down further.
* Before 5% efficiency required in R401
Prepared for the DOLA Code Cohort of Northwest Metro Area / Boulder County
Page 178Page 183
(Cost Discussion Cont'd): For mixed fuel homes, electric-ready infrastructure is estimated at
$300 for a water heater and the same for a stove (or possibly increased to $400 each with
inflation and a tight labor market). No additional costs are incurred for electric readiness for a
furnace, because central air conditioning or other space cooling would be provided anyway.
The cost of the additional two efficiency packages, required for mixed fuel homes, range from
$467 for the HVAC efficiency option to $1,453 for the ventilation option (not including
inflation since 2021).
Jurisdictions with Electric-Ready and/or Electric Preferred: Boulder, Boulder County,
Carbondale, Crested Butte (all-electric) Denver (in progress), Fort Collins, Louisville, Superior,
other Code Cohort communities (in progress). Note: a new 2022 Colorado law requires all
upcoming IECC adoptions to include electric-ready provisions equivalent to or better than a
version to be identified by the state's Energy Code Board. We highly anticipate these
amendments will be in compliance with the law.
Mild/Medium/Aggressive Rating: Medium. A “mild” rating would be just electric ready – i.e.
just the wiring and panel capacity. An “aggressive” rating would require all-electric heating and
water heating for most residential, multifamily, and commercial buildings, or, even further, no
gas connections at all.
[1] Despite a few recent studies, a couple local home builders report challenges getting the costs to "pencil out." State policies
passed since then, like the 10% tax credit for heat pumps, heat pump water heaters, and panels, plus regulatory dockets
underway at the Public Utilities Commission, in addition to incentives in the Inflation Reduction Act, may improve the cost
calculations.

Energy Code Amendments
Background
Energy Codes:
The International Energy Conservation Code (IECC) is one of a suite of model building codes
prepared and published by the International Code Council (ICC) and updated every three years
through an extensive public process. It is typically adopted by local jurisdictions as part of a
comprehensive building code update. Some jurisdictions routinely update their building codes
every three years, some “skip a cycle” and update every six years, and some update only
occasionally on an as-needed basis.
The 2021 IECC improves energy efficiency 8-9% over the 2018 IECC and 2015 IECC. This
translates roughly to 8-9% savings on energy bills. [Finish]
Recently, local jurisdictions have been adding additional provisions to the energy code, to
support local jurisdictions’ climate goals or to “future-proof” new homes and buildings for
increasingly-common technology. These additional provisions are added either through
amendments or appendices or both. They typically include some combination of solar-ready,
EV-ready, electrification (either electric-ready, electric-preferred, or all-electric with exceptions),
exterior energy offset programs, and/or net zero requirements. Sometimes these additional
provisions are called “stretch codes.”
Colorado State Law: Colorado state law has specific requirements for local energy code
adoptions, but these requirements differ based on if an adoption happens before July 1, 2023 or
after July 1, 2023. Before July 1, 2023, the “old rules” are in effect, whereby any local building
code update must include at least one of the three most recent versions of the IECC (i.e. the
2021, 2018, or 2015 edition). After July 1, 2023, the “new rules” kick in, whereby any local
building code update must include the 2021 IECC along with solar-ready, EV-ready, and electric
ready provisions. To be clear, no changes are necessary or required until a local jurisdiction
updates any other building codes.
Overview of Colorado Model Code: The legislation established an officially-appointed state
Energy Code Board to review and develop model solar-ready, EV-ready, and electric-ready code
language. Local jurisdictions can choose this model code or can adopt their own custom
language that is at least as stringent. The model code is currently titled the “Colorado Model
Electric-Ready and Solar-Ready Code.” It does include EV-ready even though that’s not in the
title. This model code is in near-final draft version; the final will be released on or before June 1,
2023.
Overview of Regional Code Cohorts:
Prior to and parallel to development of the state’s model code, local jurisdictions in Colorado
have been collaborating on drafting and adopting their own regionally-consistent code language.
The State of Colorado recently funded two separate Code Cohorts of local governments to
review, discuss, plan, and adopt regionally-consistent energy codes with supporting
amendments, the first in the Northwestern metro area and Boulder County area and the second
in Eagle County jurisdictions. Both Code Cohort cohorts independently agreed to adopt the
2021 IECC, solar-ready (expanded to include all multifamily), EV-ready, electric-preferred, and
Attachment 9
Page 180Page 185
certain efficiency strengthening amendments. The Eagle County cohort also added an Exterior
Energy Offset Program, also called a Renewable Energy Mitigation Program, which adds either
solar or a fee-in-lieu to offset outdoor natural gas uses like snowmelt or hot tubs. These cohorts
have amendment language, factsheets, and presentation slides that are available for other
jurisdictions to copy or adapt. The language adopted by each Code Cohort does comply with
state law.
Overview of Jurisdictions Going Beyond Those Options:
• Denver adopted all-electric space and water heating for commercial buildings, electric-
preferred for residential, and extra energy efficiency for both residential and commercial
• Louisville adopted all-electric space and water heating for commercial and multifamily
buildings, residential net zero requirements, and extra energy efficiency
• Crested Butte adopted an all-electric code, exempting restaurants
• Lafayette is underway adopting an all-electric code for both residential and commercial
(with exceptions including restaurants) as well as partial solar required for commercial
• Golden is underway adopting a full net zero decarbonization code
Solar
Option 1: No Change / No Adoption
New homes and buildings are allowed to voluntarily add solar at any point. The roof space may
or may not be built to accommodate solar panels. Electrical panel will likely not have reserved
space for future solar.
Option 2: Solar-Ready Appendices CB and RB (amended to include all multifamily)
The IECC includes optional Solar-ready appendices, called Appendix CB on the commercial
side and Appendix RB on the commercial side. [Finish]
- See attachment
Option 3: Partial solar required on larger commercial and multifamily buildings
- [Finish]
Electrification
Option 1: No Change / No Adoption
Option 2: Electric-Ready
Option 3: Electric-Preference
- See attachment
Option 4: All-electric with Exceptions
EV-Ready
Option 1: No Change / No Adoption
Page 181Page 186
Option 2: Code Cohort levels
- See attachment
Option 3: State Energy Code Board levels
Net Zero
Option 2: Net Zero Appendix RC
The IECC includes two optional Net Zero appendices, called Appendix RC. Adoption of this
appendix is very rare. In Colorado, only Louisville has adopted Appendix RC. Golden is
underway with adoption of a somewhat similar approach, using New Buildings Institute’s
Decarbonization Code Overlay.
Appendix RC requires homes to be built more energy-efficient than the base code, and then
requires the remaining energy use (both electric and gas) to be met through renewable energy.
In general, adoption of Appendix RC is discouraged amongst code officials, builders, and certain
advocate groups, given a combination of the cost and the bang-for-the-buck.

• Disallow gas-powered lighting (11, 36)
• Require thermal energy certification, slab insulation, and radiant heating insulation in the
commercial Total Building Performance pathway, to match the other pathways (18)
• Require an energy audit at the time of a major alteration or addition (19, 41)
• Add programmable thermostat controls anytime a commercial HVAC system is replaced
or expanded, and add a programmable thermostat anytime a residential HVAC system is
replaced or expanded (20, 42)
• Require commercial HVAC systems and water heating systems that are part of an
alteration to undergo retro-commissioning (i.e. tuning and verification that the system is
operating as intended) (23, 24)
• Require insulation around all residential hot water pipes, not just those with a diameter of
3/4 inch and greater (33)
Administrative / Clarifications
• Delete Chapter 11 of the IRC and instead require the IECC (this is standard) (1)
• Ensure renewable energy isn’t double-counted (9)
• Other Avon-specific standard or administrative amendments

Thank you Frank !
My vote is nay and I m open to a meeting amongst us as well .
Perhaps we should list reasons for our stance as a group.
Such as …
-cost
-effectiveness…being we don’t have land to create subdivisions, what’s effectiveness of having a single new home
that’s sprinkled amongst existing dozens that aren’t ?
This is a surprise recommendation and I am concerned the building department is leaving us out of the teamwork
process we established 4 years ago.

2021 BUILDING CODE
Frank Theis <ftheis3@gmail.com> Tue, Apr 25, 2023 at 12:01 PM
I recommend that the Town of Estes Park adopt the 2021 Building Code with an amendment exempting single-family
houses less than 2,000 square feet in size from the fire sprinkler requirement. This amendment would keep smaller
homes' costs lower, thus encouraging the construction of more efficient housing. Smaller homes are also more likely
to be owner-occupied year-round and more likely to house working families.
Thanks for your consideration,

2021 International Building Code
Discussion
Gary Rusu, Building Official &
Jessica Garner, AICP, Community
Development Director
April 25, 2023
Process:
all of the IBC items listed in the staff memo
On May 23rd, the Town Board will vote on the adoption of the 2021
IBC, plus the International Residential Code and the International
Pool and Spa Code
Additionally, staff presented four options in the memo for
consideration, and are seeking clarification from the Board tonight.
While the preferred option cannot be voted on tonight, the Board
can direct staff to revise the Ordinance with any of the options for
final adoption in May.
Page 186Page 191
2021 IECC + Appendices
Staff recommends adopting the 2021 Energy Code and one of the
two options:
1. 2021 IECC, plus the following appendices:
Appendix RB: Solar-Ready Provisions- Detached One- and Two-
Family Dwellings and Townhouses (Although Appendix RB does not
require solar systems to be installed for a building, it does require the
space(s) for installing such systems, providing pathways for
connections and requiring adequate structural capacity of roof
systems to support the systems)
Appendix CB: Solar-Ready Zone- Commercial (Intended to
encourage the installation of renewable energy systems by
preparing buildings for the future installation of solar energy
equipment, piping and wiring)
2. *Or the 2021 IECC, plus the Colorado Model Electric Ready and
Solar Ready Code (Exhibit E in the packet)-Staff Recommendation*
Additional IECC Appendices
Staff does not recommend adopting the Appendices below:
Appendix RC: Zero Energy Residential Building Provisions
(Provides requirements for residential buildings intended
to result in net zero energy consumption over the course
of a year
Appendix CC: Zero Energy Commercial Building
Provisions (Intended to supplement the International
Energy Conservation Code and require renewable
energy systems of adequate capacity to achieve net
zero carbon)
Page 187Page 192
Options for Consideration
Option One: Approve adoption of the 2021 IBC and related
codes with amendments presented at the Town Board
meeting on May 23, 2023, including optional Energy Code
Appendices CB and RB.
Option Two: Approve adoption of the 2021 IBC and related
codes with amendments presented at the Town Board
meeting on May 23, 2023, excluding optional Energy Code
Appendices CB and RB.
Options for Consideration
*Option Three: Approve adoption of the 2021 IBC and
related codes with amendments presented at the Town
Board meeting on May 23, 2023, including the Colorado
Model Electric Ready and Solar Ready Code, and
schedule a study session to discuss the possibility of
adding Appendices RC and CC, as well as electric-
preferred provisions presented by SWEEP at a later date.
* Staff Recommendation
Option Four: Possible Alternative as the Legislative
Authority The Board of Trustees may postpone adoption
of the 2021 International Codes or direct staff to revise
any portions of the codes.
Page 188Page 193
2021 IRC: Sprinklers
Currently, the draft IRC would require all new
single-family homes, two-family homes,
duplexes, and townhomes to have sprinklers
installed throughout the residence. Should the
Board decide to revise this requirement, staff
can make the amendment prior to the public
hearing on May 23rd.

Town Clerk Report
To: Honorable Mayor Koenig
Board of Trustees
Through: Town Administrator Machalek
From: Jackie Williamson, Town Clerk
Date: April 25, 2023
RE: Estes Park Board of Trustees Vacancy Letters of Interest
Objective:
To review the letters of interest received for the vacancy on the Town Board and
provide staff with direction on the next steps in the process to fill the vacancy, such as
conducting public interviews.
Present Situation:
As a statutory community, the Town is required to follow the guidelines outlined in the
Colorado Revised Statutes 31-4-303 Trustee to Fill Vacancy. The Board must either
appoint or set an election within 60 days from the date of the vacancy to fill the term of
the Trustee, which is May 26, 2023. If the Board does not take action within 60 days, an
election must be set to fill the vacancy. The Board considered its options for the process
at its April 11 meeting and directed staff to request letters of interest for an appointment
to the Board of Trustees to serve until the next regular Municipal Election in April 2024.
The Town Clerk has received 9 letters of interest from the following individuals, listed
alphabetically and attached to this memo for review:
William Brown Bruce Darby Nathan Harger
John Howell Frank Lancaster John Meissner
Ward Nelson Kurt Ratsch Jason Van Tatenhove
The Town Clerk has verified each individual meets the requirements to serve on the
Town Board, i.e. (1) be a United States citizen; (2) be at least 18 years old; (3) be a
resident of the Town of Estes Park for the past twelve consecutive months; and (4) be a
registered elector.
Proposal:
As noted in the previous memo of April 11, 2023, staff would bring forward the letters of
interest and discuss with the Town Board next steps in filling the vacancy, including but
not limited to holding a public interview process at an upcoming meeting or special
meeting and hold a vote to appoint an individual. The Town Board must appoint an
individual to the vacant position within 60 days, i.e. May 26, 2023.
Page 195
Sample calendar: April 25th Board to determine next steps in the process
TBD Special meeting to hold public interviews and Board
vote at conclusion of the interviews or moved to the
May 9th meeting
May 9th Hold public interviews and/or Board vote
May 23rd Swearing In
The sample calendar provides the Board with a couple of options if public interviews are
to be held. Staff recommends utilizing questions similar to the questions outlined in the
draft application provided at the previous meeting, see attached. The interviews could
be scheduled for 15 – 20 minutes and be held in the Board room. As noted above, the
Board could vote immediately following the interviews or at an upcoming meeting.
In lieu of a formal interview process, the Board could require written responses to
questions for review by the Board prior to the next Town Board meeting on May 9th.
This would eliminate the need for a special meeting; however, it does not provide the
Board the ability to ask follow up questions or determine how an individual engages the
Board and the public.
Advantages:
•Providing Town staff with direction will allow the process to fill the vacancy to move
forward, ensure quorum for meetings and maintain the number of board members
needed for a majority and super-majority votes.
•A public interview process would allow the public the opportunity to learn more about
the individuals interested in serving on the Board.
Disadvantages:
•The Board may find it difficult to identify a date to hold additional in person
processes before May 26th.
Action Recommended:
Staff does not have a recommendation on the next steps as this is a decision of the
Board. Staff requests the Board provide direction on the next steps in reviewing the
letters of interest.
Budget:
Appointment process – staff time

RE: Estes Transit Branding Project Update
Objective:
Update the Town Board on the Estes Transit Branding Project, including presentation of
the draft Brand Discovery Report, proposed new transit system name, and design
concepts for vehicle wraps.
Present Situation:
Development of a new brand for Estes Transit and complementary strategic marketing
plan to increase transit ridership was defined as a 2022 Town Board Strategic Plan goal
and has been carried over into 2023.
In fall 2022, a Request for Proposals (RFP) for Transit Branding Services was published
by Public Works (PW). Through a competitive selection process that included input from
PW staff and the Transportation Advisory Board (TAB), the Fort Collins-based Slate
Communications was selected for its robust public sector experience and previous work
with the Town of Estes Park.
The goals of this consulting engagement with Slate Communications are to:
1.Increase ridership of Town transit service offerings among locals and visitors.
2.Disperse information and increase awareness of Town transit service offerings
and service changes among the general public and targeted audiences.
3.Brand the public transit system in a memorable and unique way that is in line
with the Town’s vision and mission statements.
To date, the consultant team has completed about a third of their total project scope,
including engagement of the local community via individual meetings and two
presentations to the TAB. Additionally, a project steering committee—composed of
Town staff (PW and the Public Information Office), TAB members, and an Estes Transit
driver and representative of the Town’s contracted transit service provider—have held
frequent meetings to provide guidance to the consulting team on various creative
elements.
Page 211
Most notably, the steering committee recently participated in developing a visual palette,
design concepts for transit vehicle wraps, and a proposed new system name. Since
these elements will be foundational to the new brand and very visible to the public, PW
staff is providing the Town Board with this opportunity to review input from the project’s
stakeholder process, learn about the creative process, and provide input on the
proposed new name for Estes Transit and bus wrap design concepts.
Proposal:
Report on work completed to date for the Estes Transit Branding Project, including
presentation of the draft Brand Discovery Report and the process for selection of a new
name for Estes Transit, “The Peak.” PW staff would also like Town Board input on
proposed route-based transit bus theming and graphics.
Advantages:
•This project will help increase awareness about the Town’s free shuttle service
offerings.
•Transit branding is a proven strategy to increase ridership, which would support
Town efforts to reduce traffic congestion.
Disadvantages:
•Full implementation of recommendations from this planning process will take
time, staff resources, and financial resources; however, staff will work with the
consulting team to define a phased implementation plan and identify grant
opportunities.
Action Recommended:
None. This is a report only.
Finance/Resource Impact:
The total budget for this project is $49,815 from 101-560-456.22-98 (Transportation,
Other). Sixty-four percent (64%) of this project will be covered by grant funding. This
percentage is based on the fact that FY 2022 grants funds required zero percent (0%)
local match and FY 2023 grant funds require a fifty percent (50%) match. Funding for
implementation of several key project elements in 2023, including transit bus wraps,
updated transit stop signage, and an updated brochure/map are budgeted in 2023 in
101-5600-456.26-52 (Transportation, Traffic Signs) and 101-5600-456.26-03
(Transportation, Printing/Forms). Funding for future implementation phases will need to
be addressed on a year-to-year basis.
Level of Public Interest
Public interest is expected to be low to moderate.
