TOWN OF ESTES P
Report PUBLIC WORKS
To: Honorable Mayor Koenig
Board of Trustees
Through: Town Administrator Machalek
From: Trevor Wittwer, Civil Engineer
Greg Muhonen, Public Works Director
Date: March 28, 2023
RE: 2023 Street Improvement Program Overview
Purpose of Study Session Item:
Provide the Town Board an update on the 2023 Street Improvement and Trail Expansion
Programs funded by the 2014 1A Tax Initiative.
Town Board Direction Requested:
Confirm acceptance of the proposed scope of work.
Present Situation:
• In 2014 the citizens of Estes Park voted to increase the sales tax by one percent with 60%
of the increase going toward street improvements and 12.5% going toward trails expansion
in the Town of Estes Park.
• A goal was set to raise the system-wide Pavement Condition Index (PCI) to above 70 by
the end of the term of the tax in 2024.
• The Public Works Department has continued to expand our trails system in accordance
with the Estes Valley Master Trails Plan.
• Larimer County plans to overlay some of their roads in Estes Park in 2023 using in-house
labor. Rather than skipping the Town-owned segments on these county roads, Public
Works is partnering with the County to have County crews overlay our road segments at
the same time. This collaboration is estimated to save Estes Park taxpayers approximately
$15,000.
Proposal:
The 2023 Street Improvement Program (STIP) consists of overlaying 1.7 centerline miles of
roadway, asphalt patching at 15 roadway locations, crack sealing 6.5 centerline miles of roadway,
and chip sealing 3.3 centerline miles of roadway. Design projects occurring in 2023 include the
Visitor Center Parking Lot reconfiguration, Reclamation Neighborhood, and Cleave Street
Improvements.
Trail Expansion work in 2023 includes construction of three separate projects: Fall River Trail
(Colorado the Beautiful grant), Fall River Trail (Transportation Alternatives Program & Multimodal
Page 3
Transportation and Mitigation Options Fund grants), and Graves Avenue Improvements (Safe
Routes to School grant). These projects will add approximately 0.8 miles of surfaced trail to the
Town's trail network.
Advantages:
• This plan continues the work set forth in the original 2024 STIP Plan.
• Implementation of this plan will result in improved road conditions throughout Town, leading
to higher citizen and guest satisfaction.
• This plan includes preventive road maintenance, which will impact a larger percentage of
the roads in Town, as opposed to only focusing on a few major repairs.
• The entire road system is predicted to exceed an average PCI rating of 70 by the end of
this program. We reached this system-wide average score in 2018 and will continue to plan
cost-effective projects in order to maintain a PCI above 70 for the remainder of the program.
Disadvantages:
• Increased construction during the course of this program will produce localized detours
and delays for motorists during construction periods; however, contractors will follow
approved traffic control plans, and full road closures will be minimized as much as possible.
• The average system-wide PCI is expected to be above 70 in 2024; however, there will be
some roads with PCI ratings below 70 (approximately 23% of our system below 70).
Finance/Resource Impact:
The proposed street improvements are funded through the 1A Street Improvement Fund (Fund
260). The proposed trail improvements are funded through the 1A Trail Expansion Fund (Fund
244), the Larimer County Open Space Fund (Fund 220), and the Community Reinvestment Fund
(Fund 204). For 2023 the proposed spending is:
$900,000 — Overlays and Patching
$280,000 — Chip and Crack Sealing
$325,000 — Personnel, Spray Patcher, Striping, Equipment, etc.
$50,000 — Engineering Design Costs
$129,000 — Visitor Center Parking Lot (Design)
$485,000 — Fall River Trail: $364k from Colorado the Beautiful (CtB) grant; $110k from Town;
$10k from Larimer County Department of Natural Resources (DNR); $50k from Estes
Valley Recreation and Park District (EVRPD)
$3,375,000— Fall River Trail: $955k from Transportation Alternatives Program (TAP) grant; $448k
from Multimodal Transportation Mitigation Options Fund (MMOF) grant; $718k from
Town; $100k from EVRPD
$900,000 — Graves Avenue Improvements: $500k from Colorado Safe Routes to School (SRTS)
grant; $400k from Town
Level of Public Interest
The known level of public interest in this item is moderate.

Streets Improved - 1A Sales Tax
Approximately 85% of roadway segments have been
crack sealed, chip sealed, patched, or overlaid
through 1A program.
Pothole repair spray patcher performs hundreds of
additional minor patching repairs each year.
On target to achieve PCI goal at end of program
Pavement degradation is perpetual. Revenue from 1 A
tax is critical for maintaining PCI over the entire life
of the roadway. Renewal in 2024 is very important.

Principles of IPMC
• The IPMC is a maintenance document intended to establish
minimum maintenance standards for basic equipment, light,
ventilation, heating, sanitation and fire safety.
• Provides requirements for continued use and maintenance of
building elements, site conditions, swimming pools, plumbing,
mechanical, electrical and fire protection systems in existing
residential and nonresidential structures.

Recommendations to adopt Chapters 1& 2 of the
i021 IPMC
• Chapter 1 Scope and Administration
• Chapter 1 establishes the limits of applicability of the code and
describes how the code is to be applied and enforced.
• Chapter 1 is divided into two parts:
• Part 1, Scope and application (Sections 103- 110)
• Part 2, Administration and enforcement (Sections 103- 110)
• Section 101 identifies which buildings and structures come under its
purview and references other I-codes
Recommendations to adopt Chapters 1& 2 of the
2021 IPMC
• Staff recommends adopting Chapter 2, Definitions,which clearly
state what specific terms mean for the purpose of this code.
• Codes by their nature are technical documents. Every word, term
and punctuation mark can add or change the meaning of a
technical requirement. It is necessary to maintain a consensus on
the specific meaning of each term contained in the code.

Standardized Amendments to the 2021 IECC
Estes Park,Colorado
Climate Zone 5B
RESIDENTIAL
1. Amend as follows: R101.1 Title.This code shall be known as the Energy Conservation Code of The Town of Estes
Park, Colorado, and shall be cited as such. It is referred to herein as "this code"
2. Delete in its entirety: R401.2.4 Tropical Climate Region Option.The Tropical Climate Region Option requires
compliance with Section R407.
3. Add additional sentence to Section R406.4 Energy Rating Index to read as follows:
R406.4 Energy Rating Index.The Energy Rating Index(ERI) shall be determined in accordance with RESNET/ICC
301 except for buildings covered by the International Residential Code, the ERI reference design ventilation rate
shall be in accordance with Equation 4-2.
Ventilation rate, CFM = (0.01 x total square foot area of house) + [7.5 x (number of bedrooms+ 1)]
(Equation 4-2)
Energy used to recharge or refuel a vehicle used for transportation on roads that are not on the building site
shall not be included in the ERI reference design or the rated design. For compliance purposes, any reduction in
energy use of the rated design associated with on-site renewable energy shall not exceed 5 percent of the total
energy use.
A HERS Index Score may be utilized in lieu of the ERI score.

MU'rinciples of IECC
• To establish provisions consistent with the scope of an energy
conservation code that adequately conserves energy; provisions
that do not unnecessarily increase construction costs, nor give
preferential treatment to particular types or classes of materials,
products or methods of construction.
• The code development process brings together building
professionals on a regular basis. It provides an international forum for
discussion and deliberation about building design, construction
methods, safety, performance requirements, technological
advances and innovative products.

Application of the 2021 IE
The 2021 Energy Code and all I-Codes clarify code sections.
However, the impact of the codes extends well beyond the
regulatory arena, as they are used in a variety of nonregulatory
settings, including:
1. Voluntary compliance programs such as those promoting
sustainability, energy efficiency and disaster resistance
2. The insurance industry, to estimate and manage risk, and as a
tool in underwriting and rate decisions
3. Certification and credentialing of individuals involved in the
fields of building design, construction and safety
3
4. Certification of building and construction-related products
5. US Federal agencies, to guide construction in an array of
government-owned properties
6. Facilities management
7. "Best Practices" benchmark for designers and builders, including
those who are engaged in projects in jurisdictions that do not
have a formal regulatory system or a government enforcement
mechanism
8. College, university and professional school textbooks curricula
9. Reference works related to building design and construction

Staff Recommendations
• 2021 Energy Code-The compliance path options have been
clarified and the prescriptive and mandatory labels have been
removed
• Staff strongly recommends not adopting Appendix RB (Solar ready
provisions for one and two-family dwellings and townhomes)
■ Staff recommends not adopting Appendix RC (Zero Energy
Residential Provisions, adopting the Appendix would replace Section
R401.2)

Commercial buildings shall comply with one of the
following:
1 . Prescriptive compliance. The prescriptive compliance
option requires compliance with Sections C402
through C406 and C408.
2. Total building performance. The total building
performance option requires compliance with Section
C407.
11
■ C403, 2, 3 Fault detection and diagnostics.
■ New buildings with and HVAC system serving a gross
conditioned floor area of 100,000 square feet or larger
shall have a FDD system to monitor the HVAC
performance and automatically identify faults.
■ The 2021 Energy Code now requires the HVAC systems
to be more efficient. That can be accomplished by
different mechanical means.

Prepared for the DOLA Code Cohort of
Northwest Metro Area/Boulder County
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.)
Increased First Annual Energy Years to Positive Lifecycle Cost
Cost(vs 2015) Mortgage Increase Savings Net Savings Savings Savings
$3,376 $122 $161 $20/yr 9 $1,247
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)
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.
