Agenda Item 22
Item # 22 Page 2
The purpose of this item is to adopt the most up-to-date, comprehensive, and fully integrated body of codes,
the 2018 International Codes (2018 I-Codes), regulating building construction and systems using prescriptive
and performance-related provisions. The purpose of these Codes is to establish the minimum construction
requirements to safeguard the public health, safety and general welfare by regulating structural strength and
stability, sanitation, light and ventilation, energy conservation, and property protection from hazards attributed
to the built environment within the City of Fort Collins. With factoring in local amendment costs, it is estimated
the overall cost increase to build under the 2018 codes is less than 1%.
Because this is the first time the City is adopting the International Existing Building Code (IEBC) and
International Pool and Spa Code (IPSC), as separate codes, all language being added to the City Code must
be shown as yellow. Language that is being added as local amendment is highlighted in grey so that it is easily
distinguishable from already-existing language in the IEBC and IPSC.
STAFF RECOMMENDATION
Staff recommends adoption of the Ordinances on First Reading.
BACKGROUND / DISCUSSION
Since 1924 the City of Fort Collins has periodically reviewed, amended, and adopted the latest nationally
recognized building standards available for the times. The City has updated the minimum construction
standards fifteen (15) times since 1924.
The 2018 International Codes will replace the 2015 editions of the IBC, IRC, IMC, IFGC, and the IECC which
were adopted on July 17, 2017. Even though the 2015 Codes were adopted not long ago, this 2018 Code
adoption is important for the following reasons:
• Maintain the highest ISO insurance rating which affects homeowner insurance rates in the community. The
best score is achieved by adopting the most recent series of Codes within 12 months of issuance.
• Many other communities in the area and Larimer County will be adopting the 2018 Codes in early 2019
and this will provide consistency and maintain regulations in the region.
• The 2015 City of Fort Collins Energy Policy has committed to adopting the newest IECC Energy Code
within 12 months of issuance.
• Adopting each 3-year code cycle typically means Code changes are in small steps instead of large, costly
ones.
Some code provisions formally located within the above listed codes have been relocated into new separate
codes such as the IEBC and the ISPSC. These are included in this proposed adoption process; however, the
requirements in these two standards have not changed from the previous code sections located in IBC and
IRC.
Building codes and standards are reviewed and voted on by code officials and construction industry
professionals from across the country and published every three years under the oversight of the International
Code Council (ICC). These core 2018 I-Codes represent the latest construction publications from ICC.
Review process
The implementation of new building standards can have a dramatic impact on the construction industry and the
economy of the community. To better understand these impacts, a Code Review Committee is convened
(Attachment 1) for the purpose of reviewing the new codes and all local amendments. The code review
committee represents a wide spectrum of volunteers from across the local construction industry, including
private developers, residential and commercial builders, architects, engineers, representatives from the energy
conservation sector and Poudre Fire Authority.
Agenda Item 22
Item # 22 Page 3
The Code Review Committee met regularly in July, August, and September 2018 to discuss new proposed
amendments and current amendments. In September, the Code Review Committee found that the proposed
amendments are neither controversial nor overly onerous or cost prohibitive on the construction industry and
voted to support and moved for adoption of the 2018 I-Codes and amendments. While this review process
requires considerable time and resources, it produces enforceable and effective building codes and
amendments that the community and construction industry support and create together.
Changes in the new 2018 Codes
There are a few dozen changes in the 2018 Codes, but they are considered minor or only adding clarity. The
committee did identify one change worth noting:
The Energy Code window u-value will change from .32 to .30. This increase in efficiency has an approximate
cost increase of 8% for vinyl windows. This will add an upfront cost of $200-$300 to the cost of the window
package for an average size house, but could reduce ongoing energy costs over the lifetime of the home.
While the ROI is small with this step, the Energy Board agrees any increase in efficiency is the right direction.
Local Amendments Overview
Local amendments are changes to the proposed Code or new Code regulations that are added due to
life/safety concerns or from local priorities. Many of the current local amendments are now incorporated into
the new 2018 Code as written (the International body of codes have caught up to many of Fort Collins local
amendments). As a result, several amendments have been removed, as they are no longer necessary. Other
amendments that did not have the intended results or were shown to be ineffective and an unnecessary cost
burden to the construction industry were modified or removed. Being mindful of the City’s Climate Action Plan,
any removal of amendments was done without forsaking gains in energy efficiency. Overall the changes from
the 2015 Codes to the 2018 Codes are few and impacts to cost of construction are minimal.
A handful of new local amendments are being proposed:
• The definition of Imminent Danger has been revised to add clarity and convey the urgency involved in
taking action. The language “at any time” has been changed to “immediate”.
• When a trash chute is provided in new multi-family buildings, a second chute for recycling must be
provided. This can be achieved in the same fire-rated shaft to reduce costs. Cost increase is
approximately. $1500 per floor.
• In new multi-family, 10% of all parking spaces must provide an empty conduit from the electrical room to
the front of the parking space for the purpose installing electric vehicle charging equipment in the future.
Approximate cost increase is $300 per parking space.
• A new, no-fee emergency repair permit provision was added to allow a fast permit to be issued in a
disaster/damage situation where a building owner can temporarily repair a dwelling and obtain inspection
to allow occupancy while more permanent repairs are forthcoming. This was recommended by the Larimer
County Building Department, who scrambled to put this in place after several recent disasters.
• Responding to a concern by the Chamber of Commerce, the requirement to install a fire-sprinkler system
in an in-home daycare (5 children maximum) has been removed. In-home daycares are not required to
change the building occupancy (remains single-family) and these are state regulated. Neither the City nor
Poudre Fire Authority is notified of these. If that requirement changes, requiring these owners to fire-
sprinkler could have a large negative effect on the number of these businesses approved in Fort Collins
due to the high cost of these sprinkler systems. PFA supports this change.
• All structures choosing to install asphalt shingles will be required to use class 4 impact resistant shingles.
A requirement for reroof projects to report the amount of waste and final waste location will be added, as
well. The cost increase for an average size home to install Class 4 shingles is $500 - $1000, or 5%-10%
increase over normal shingles.
Agenda Item 22
Item # 22 Page 4
• To reduce water consumption, showerheads will be lowered from 2.0 gallons per minute (gpm) to 1.8 gpm
and non-residential faucets lowered to .5gpm. In addition, the flushing performance requirements of new
water closets will increase which should reduce multiple/failed flushes. Research conducted by water
conservation staff did not identify any substantial costs increases.
• Responding to a concern by the Commission on Disability, the required roll-in showers provided in new
multi-family and hotels, will be larger, from 30”x60” to 36”x60”. The impact (approximately $100 per
shower) is minimal since those size shower pans are readily available and most projects only require one
to four roll-in showers depending on the number of dwelling units/sleeping units.
The cost assumptions discussed in each bullet above were calculated based on outreach to professionals in
the building industry, such as general contractors, electricians, plumbers, mechanical contractors, and fire-
suppression contractors. Construction supply houses were contacted for an estimate of off-the-shelf materials.
Factoring in local amendment costs listed above, it is estimated the overall cost increase to build under the
2018 codes is less than 1%.
Council follow-up from the Dec 4 meeting regarding plumbing fixture flow rates
The purpose of this section is to answer questions raised by City Council and the public at the December 4,
2018 meeting regarding the proposed code change in water flow rates of showerheads, faucets, and flush
performance of water closets.
Based on additional research and outreach with stakeholders, staff proposes the following three options:
1. Approve the plumbing fixture changes as originally outlined in this adoption package.
2. Remove these fixture flow rate changes and keep the current flow rates as adopted in 2012.
3. Approve the plumbing fixture changes as originally outlined in this adoption package and include certain
exemptions: (staff recommendation based on additional research and input)
• Exempt I-occupancies (e.g., hospitals, assisted living facilities) and E-occupancies (e.g., K-12
schools, day care facilities) from the 1.8 gpm showerhead flow requirement, as these include more
vulnerable populations.
• Exempt I-occupancies (e.g., hospitals, assisted living facilities) in addition to the already proposed
R-occupancy (residential) exemption from the commercial private lavatory 0.5 gpm requirement.
Background & History
In 2012 as part of the green code initiative, the max flow rates for plumbing fixtures was reduced from the code
maximum as shown below to reflect EPA WaterSense standards. Effective September 1, 2016, Colorado
Senate Bill 14-103 requires manufacturers to only sell WaterSense-labeled fixtures to distributors, wholesalers,
retailers, developers and homebuilders for the sale/resale or installation in the State of Colorado.

Agenda Item 22
Item # 22 Page 5
There is a proposed change in the local amendments to the International Plumbing Code (IPC) and 2018
International Residential Code (IRC) to lower the allowed gallons per minute (water flow rate) of commercial
faucets and all showerheads and making a change to the toilet flush performance requirements. The intent is
reduction in water consumption and improved fixture performance.
• Showerheads would be lowered from 2.0 gallons per minute (gpm) to 1.8 gpm.
• Commercial lavatory faucets would be lowered from 1.5gpm to .5gpm, but only for non-residential
occupancies.
• Water closet (toilet) flushing performance (MaP score) will rise from 350 to 600 MaP improving flush
performance and reducing multiple, failed flushes.
Code Review and Adoption Process
1. September 2018 City water conservation staff requested that Building Services and the Water Board
support a code change to improve toilet efficiency and performance by decreasing the gallons per flush
(gpf) from 1.28 to 1.1 and increasing the Maximum Performance (MaP) score from 350 to 600 grams and
consider increasing the efficiency of other fixtures as well. Water board recommended increasing the
efficiency of all 8 fixture types shown in the plumbing sections of the code.
a. The Chief Building Official presented this proposal to the Building Code Review Committee and
discussion concluded more information was needed for decision. All decisions listed below were
made by the committee with input from city staff and stakeholders.
b. Additional research was conducted on flow rates of other fixtures such as lowering toilet flow from
1.28 to 1.1 gpf. The committee found that these toilets are readily available, and the additional cost
would be $30 for 1.1gpf for a low-end toilet. After discussions with Wastewater Utility staff there is
an interest in further understanding what the impacts of retrofitting to high-efficiency toilets in
existing commercial buildings or locations with older waste piping material. As verified by recent
research, there is little to no need for concern in residential settings. More information on this item
is provided later in this memo. The Building Code Review Committee conducted independent
research on the cost and availability of toilets meeting the 600 MaP score and had no concerns.
i. The decision was made to not lower the flow rate of all 8 fixtures, at this time, and first
focus on just the flow rate of showerheads, faucets, as well as improving the toilet flush
performance requirement, but not the flow rate of the toilet.
c. In early October, City staff was contacted by two plumbing industry groups Craig Rogers from the
manufacturer Waterpik and Matt Sigler from Plumbing Manufacturers International (PMI), a trade
organization that represents the plumbing manufacturing industry. We corresponded many times
to address their concerns as listed below:
i. They urged this process to not lower the showerhead flow rate from 2.0gpm to 1.75
gpm and listed reasons including facts such as some certifying agencies only test to
one-digit flow level therefore if we change it should be 1.8gpm or 1.7gpm. Staff verified
that the one-digit flow level claim was not accurate but made the change anyhow to
reflect California’s recent decision to require 1.8 gpm showerheads. As a result, there
are more products available that meet 1.8 vs. 1.75. This change is also consistent with
California’s recent change. The showerhead flow rate recommendation was changed to
1.8gpm.
ii. They were concerned about the measurement of GPF for dual flush toilets. Staff
changed the calculation to reflect WaterSense methodology for determining GPF
(average of 2 low and 1 high flush). This change is more lenient and allows more dual
flush toilets to meet the GPF requirement.

Agenda Item 22
Item # 22 Page 6
iii. They expressed concerns regarding a MaP score of 600. Staff and Committee
considered but elected not to make any changes to the proposal on the grounds that
toilet performance is not consistent and home and building owners would benefit from
this change as well as builders who would receive complaints less frequently. Water
Conservation staff believes an increase in performance will reduce the misconception
that WaterSense toilets (even at the minimum 1.28 gpf) are poor performing.
iv. They also pointed out an error in the current plumbing code amendment which required
all fixtures to be WaterSense labeled however not all fixtures are tested by
WaterSense. Details were added in this code section to only require fixtures that are
tested by WaterSense to be WaterSense labeled.
v. They expressed concern about lowering the lavatory faucet flow rate from 1.5gpm to
0.5gpm for residential occupancies. After discussion with the Committee and staff, this
was changed to continue to allow 1.5gpm for all residential type uses (hotels, dorms,
apartments, condos, etc.) where faucets are used for more than hand-washing.
d. Following the December 4, 2018 City Council meeting, staff reached out to the individuals who
had provided public comment. As of the date of this memo, staff received a response from 3 of
the 4 that provided public comment.
i. On Monday, December 10, staff met with three representatives from Waterpik at their
facility. Waterpik expressed three primary concerns and staff responded as follows:
1. Poor customer experience and resulting complaints due to lower flow rates
(gpm less than 2.0). Waterpik reported 44 complaints from customers in 2015
and 89 in 2018, with only a slight increase in overall sales during this time
period. Waterpik stated that most of the complaints were from customers who
purchased 1.8 or 2.0gpm models. These complaints were collected from
customer comments left on Home Depot, Waterpik and Amazon websites
reflect comments collected nationwide. In response, staff shared our positive
experience and customer feedback received from either Utilities’ or our partner
organizations’ installation of 1.5gpm showerheads. Waterpik believes using
feedback from the conservation program is misleading, because these are
voluntary programs.
2. Dissatisfaction with 1.8gpm will lead to individuals removing the regulator and
increasing flows beyond the fixtures’ rated amount. Waterpik stated that they
don’t have numbers on the frequency of this occurrence, but some of the
comments left on their websites and vendor websites indicate customers are
doing this to improve their experience. There are lots of YouTube videos that
show individuals how to do this.
3. Potential health issues resulting from high efficiency fixtures due to lowered
chlorine residuals. In response, staff explained the intent to follow up with
internal staff from Water Quality and our prior discussions with Drexel
University, regarding the health risks associated with a showerhead lower than
2.0gpm. (More on Drexel University’s analysis is provided under Showerheads
(section b.vii.3) below.
ii. On Monday, December 10, staff spoke with Cambria McCleod from Kohler regarding
Kohler’s concerns with a 600 MaP score. Kohler referenced the original study done to
quantify the 250 grams as the 95th percentile and believes 350 grams is enough (this
study is discussed further in this memo). Kohler believes 600 grams is “extreme” and
unnecessary and will result in a focus on designing to remove bulk waste at the sacrifice
of light waste removal performance. As a result, Kohler believes customers will be misled
by a higher MaP score and dissatisfied with those toilets. Staff responded questioning the
sample size, region and age of this study to accurately determine the amount of modern-
day waste in the US. (Ms. McLeod offered to have PMI provide other studies that have
also been done that support this). Staff asked about the ASME requirements that all
toilets sold in the US must adhere to and includes a pass/fail test for light and bulk waste
Agenda Item 22
Item # 22 Page 7
removal performance. Staff’s assumption was that if ASME is testing for these things, light
waste will be addressed, regardless of the MaP score (more on ASME is provided, later in
the memo). Ms. McLeod explained that it is true to a certain extent, but the manufacturer
may focus on bulk weight performance and could only meet the minimum performance
threshold to pass ASME’s light waste removal test. Ms. McLeod and Staff discussed
Kohler’s products and their toilets’ MaP scores. Kohler has 89 toilets that are MaP tested
at or above 600 MaP and only two toilets that are at 350 MaP. Ms. McLeod’s response
was Kohler can provide a balance between light and bulk waste removal, without
compromising performance of one to focus on the other – other toilets might not be able to
do this as well.
iii. All groups – Waterpik, Kohler and PMI who had either commented before or during the
December 4 Council meeting – will be provided a copy of this information in advance of
the December 18 Council meeting.
Intent of recommending local amendments to plumbing fixtures and fittings
2. There are several reasons for exploring local amendments to the plumbing fixtures and fittings in the
building code, including:
• achieving cost-effective water savings and
• helping ensure high performance of high-efficiency fixtures.
City Council approved and adopted the City of Fort Collins Water Efficiency Plan in early 2016, which includes
a goal of reducing use to 130 gallons per capita per day by 2030. The Plan includes five Areas of Opportunity
that have been our strategic focus areas. “Encourage greater integration of water efficiency into land use
planning and building codes” is one of these focus areas. Our Plan reflects the Colorado Water Plan which has
identified a tactic to “explore legislative options and support for indoor plumbing-code standards”. Building
code changes can be one of the most cost-effective ways to achieve guaranteed water savings over time. It
also helps ensure new development is both water-efficiency and meets high performance standards to stand
the test of time. This approach is in line with other local sustainability efforts that demonstrate the role of local
action to affect local outcomes (e.g. Climate Action Plan).
As noted, staff initially proposed several changes to the eight different fixtures and fittings (Attachment 2).
Water Board was supportive of all recommendations. After conservations with Building Code Review
Committee and plumbing manufacturers, we ultimately settled on these changes to start. Staff has a plan in
place to continue research and outreach between now and the next Building Code Update in 2022.
Follow-up from Public Comment Received at December 4 City Council Meeting
3. Public comment presented at the December 4, 2018 City Council meeting are addressed below. In
general, Staff finds these changes to be a compromise reflecting a wide-variety of stakeholder interests,
including input from plumbing manufacturers and local builders and developers. Staff has not found
credible evidence of customer complaints. Staff has determined that the recommended changes will
have no cost impact, will improve performance, and will achieve water savings in new development.
Responses to public comment are generally grouped into two sections: Toilets, Showerheads, and
Other.
a. Toilets:
i. The baseline Environmental Protection Agency (EPA) WaterSense program standard has
two main goals: (1) water efficiency, and (2) flush performance. Staff is not recommending
a change to the water closet (toilet) water efficiency requirement of 1.28 gallons per flush
(gpf) at this time. Despite significant potential for water savings and support from the
Water Board, it was clear that the local builder and developer community was
uncomfortable with the potential impacts to sewer drain line design and carry. A series of
studies on the drainline transport of solid waste from the Plumbing Efficiency Research
Coalition (PERC) determined that there is no concern for sewer drain line carry for 1.28gpf
toilets in either commercial or residential settings (2). In fact, studies show that any toilet
Agenda Item 22
Item # 22 Page 8
above 1.0 poses no risk in a commercial setting and 0.8 gpf toilets are satisfactory in
residential settings. Staff will continue to research this topic and will work with both internal
staff (like the Wastewater Utility) and the builder and developer community to determine
the best recommendation for the next cycle of Building Code Updates.
ii. Staff and the Building Code Review Committee agreed that a performance requirement
would be appropriate and welcome at this time. The minimum EPA WaterSense
performance criteria is a pass/fail test of whether the toilet can clear 350 grams of test
media among the other comprehensive plumbing fixture requirements of the national
standard from the American Society of Mechanical Engineers (ASME) (3). Staff
recommends increasing the performance score from 350 grams to 600 grams. Public
comment indicated concern that increasing this “bulk score” would negatively impact the
performance of light weight media removal. This is not a concern as all toilets will still need
to be the base requirements of ASME, which include a light weight media removal test, in
addition to demonstrating the recommended improved performance for bulk flushing.
iii. The current code already requires a 350 gram “MaP” score (4). Maximum Performance
testing (MaP) identifies how well toilets remove bulk waste using realistic test media. MaP
also grades each toilet on performance (i.e. “test to failure” approach as opposed to the
ASME pass/fail approach for all tests). To provide some background on the need for a
“test to failure” approach: The Energy Policy Act of 1992 required that by 1994 the
efficiency requirement of all toilets sold would be no more than 1.6 gallons per flush.
Unfortunately, many manufacturers complied by making simple adaptions to their existing
3.5 gpf toilets, which were then rendered ineffective at eliminating waste material.
Customers complained. The ASME standards evolved over the years to require better
performance that would not put customer satisfaction and water efficiency at odds,
however, many still remember these poor performers of the 1990’s and distrust water
efficient toilets. In 2002, a group of cities and water utilities across Canada and the U.S.
worked to create standards that, among other things, established a minimum acceptable
flush performance threshold and enable consumers to compare toilets based on flush
performance. The result was the MaP testing protocol, first released in 2003. The EPA
WaterSense program launched in 2006. EPA WaterSense criteria requires 350 grams of
MaP media as the minimum performance threshold. The average MaP score of toilets in
2003 was 336 grams, and in 2017 it was 882 grams, demonstrating that manufacturers
have improved design and performance significantly since the first introduction of “low
flow” toilets in the 1990s.
iv. Public comment stated that “250 is the 95th percentile and 350 is the 99th percentile” and
therefore should be good enough for customer satisfaction and performance. The
minimum “acceptable” range of 250-350 grams was based on studies in the 1970s by a
group of British researchers. The main study in 1978 on variability in colonic function
followed only twenty subjects over 4-6 weeks (5). Staff believes these studies are out of
date, represent a small sample size, and do not likely reflect the colonic function of
average Americans and current diets. If a score of 350 grams was adequate, staff would
assume we wouldn’t have the rate of failure, shared with staff by the Building Code
Review Committee, that the Committee members have experienced in their new
construction projects. The Committee reported receiving frequent call backs during the
warranty period of a building or home, and customer requests to replace the toilet. This
group performed independent research and determined that this wouldn’t impact cost or
availability.
v. A score of 600 grams is the threshold between the “Recommended” and “Highly
Recommended” ranges. This level improves performance without impacting availability
and customer choice. Improving performance will reduce the need for repairs and “double-
flushing”.
Agenda Item 22
Item # 22 Page 9
1. While a 600 gram MaP score this is a unique requirement for building codes, the
City has required a MaP score since 2012, and this change would only be an
increase to the existing MaP requirement. Staff recommends this change to
improve performance, quality, and to provide transparency to consumers. Based
on research and feedback from the Building Code Review Committee, these
toilets are cost-effective, readily available, and often the toilets already installed.
vi. Public comment included concern for availability of these products. Of the over 1,600
toilets that are MaP tested and WaterSense certified, about 97 percent meet the 600 gram
MaP score requirement. 91 brands produce toilets that meet the requirement. On average,
62 percent of a brand’s toilets meet the requirement. When visiting Home Depot online on
December 7, 2018, all twenty of the toilets available in-store at both Fort Collins stores
meet the 600 grams or higher requirement. In fact, 18 of them have a MaP score of 1,000
grams and the MaP score is listed on the Home Depot website; this demonstrates that the
information is available to the public. Doing a similar review of Lowe’s availability, 18 of the
27 toilets available for in-store pick up had a MaP score of 1,000 grams. The remaining
nine have not been MaP tested and six of those are the Lowe’s store brand Aquasource.
vii. Virtually all commercial high-use toilets (flushometer styles) that are WaterSense and MaP
tested have a score of either 800 or 1,000 grams. As staff already does for Utilities rebate
programs, staff can post a regularly up-to-date list of qualifying toilet models to help with
the transition.
viii. Public comment included concern around the dual flush language. This was discussed
and resolved with plumbing manufacturers prior to the City Council meeting. Previously
dual flush criteria were not specifically included in the code, meaning the single efficiency
criteria of no more than 1.28 gallons per flush could have been interpreted in several
ways. Public comment included a concern that the dual flush criteria could somehow make
the toilet requirement ineffective. The language added by staff is the same language used
by the EPA WaterSense program: “…the effective flush volume is the average flush
volume of two reduced flushes and one full flush” (6). There is no reason that this will
render the code or toilets ineffective.
ix. Fort Collins Utilities and our partnering organizations have extensive experience and
customer feedback from water conservation programs that install toilets with 800 MaP
scores. The Larimer County Conservation Corps (LCCC) Water and Energy Program
installed 110 Niagara Stealth (0.8 gpf and 800gram MaP score) last year. There were
only two complaints of toilet backups, and both times the line was scoped, and it was
concluded that the issue was a result of the service line being impacted by tree roots.
Tony Pastrana works for Neighbor to Neighbor, a property management organization that
manages and does maintenance for some of the properties where LCCC has install
toilets. Tony stated that he has not received any complaints from tenants and has never
had any back-up issues with the 800gram MaP toilets that LCCC installed. Through our
2018 commercial rebate program, there have been over 1,000 0.8 gpf toilets, with MaP
scores of 800 or more, installed in multi-family units and we have not received a single
complaint. Customer satisfaction could be due, in large part, to the program only installing
higher MaP score toilets.
x. As we transition to information about showerheads, we first address the public comment
concern that the recommended changes will results in twice as many flushes or twice as
long showers. There is no evidence of either. Two large, comprehensive studies on water
usage from 1999 and 2016 gathered extremely granular data on all end uses of water
across hundreds of homes in various U.S cities, including Fort Collins (7). These studies
found that the average number of flushes per person was 5.05 in 1999 and was 5.00 in
2016. This indicates that flushing behavior has not increased despite increasing
Agenda Item 22
Item # 22 Page 10
installations of high-efficiency toilets. 2016. This indicates that flushing behavior has not
increased despite increasing installations of high-efficiency toilets.
xi. This study also found that average shower duration (7.8 minutes) and number of showers
per household per day (1.8) has not changed since 1999 either. A further analysis in 2017
comparing the 1999 to 2016 datasets found that people do not compensate for lower flow
rates with higher shower times and that lower flow rates do result in water savings (8). An
earlier 2005 EPA retrofit study of three cities found a 28 percent reduction in water savings
from installing 1.75 gpm showerheads (9). This effort included a customer survey that
showed the average rating was 4.51 out of 5 for the showerheads. Shower duration in all
three cities decreased post-retrofit.
b. Showerheads:
i. Public comment included concern for the availability of 1.8gpm showerheads. There are
many options and styles offered for 1.8 GPM showerheads, and in a wide range of price
points. There are over 4900 different showerheads available, from over 90
brands/manufactures, that would meet the proposed code change to 1.8gpm. Ferguson
Plumbing offers 139 products, from over 10 brands that would meet the change to
1.8gpm. Lowes has 183 showerheads that would meet the change to 1.8gpm. Home
Depot carries a large selection of both 1.8 and 2.0gpm. There are very little cost
differences between 2.0 and 1.8 GPM. At Home Depot the price range for 1.8gpm
showerheads is $2.27 - $526.16. For 2.0 the range is $7.47-$429.00. At Lowes and
Ferguson Plumbing, the price ranges for 1.8 and 2.0gpm is comparable to Home Depot,
with many inexpensive products available in the $5-15 range for both flow rates.
ii. Public comment included concern that “2.0 is already tested for flow force and coverage,
no additional standards for 1.8”. A 1.8gpm showerhead must meet the exact same ASME
performance standards as a 2.0gpm showerhead so there will be no sacrifice in
performance, but a benefit of water savings (10).
iii. The California statewide requirement for showerheads decreased to 1.8gpm on July 1,
2018. Public comment included concern that this mandate hasn’t been “proven over time”.
Prior to recommending and implementing the statewide change back in 2016, the
California Energy Commission conducted a comprehensive analysis the cost-
effectiveness and technical feasibility of the new standard. They concluded that this
change helps California “Planning for future drought and climate change, while also
ensuring it makes sense for consumers and the marketplace” and furthermore, based on
studies of drain line carry concluded that the showerhead standard will not impact sewer
performance. Along with support from the Building Code Review Committee, staff deemed
this extensive level of analysis and research more than enough to recommend the
change.
iv. Public comment included concern that a change in showerhead flow rate requirements
might lead potential residents to locate elsewhere. There is no evidence to suggest that a
difference of 0.2gpm in a showerhead flow rate will result in someone choosing to locate
elsewhere. This concern was not shared by the Building Code Review Committee, who is
composed of commercial and residential builders that are closely connected to their
clients. The Committee likely understands their customer’s tolerance for certain changes
and reviewed and approved this change.
v. Fort Collins Utilities and our partnering organizations have extensive experience and
customer feedback from water conservation programs that install 1.5 gpm showerheads
and other high efficiency fixtures. Since 2015 Larimer County Conservation Corp has
installed over 1,000, 1.5gpm showerheads with very little complaints. Utilities residential
rebate program provides a rebate on 1.5gpm showerheads. The Xcel Multi-Family
program installs 1.5gpm showerheads, with over 300 installations in 2018. The Utilities’
Peak Partners electricity demand response program has installed 1230, 1.5gpm
showerheads to offset potential changes to water heating schedules, with very few
complaints. In 2018, Efficiency Works commercial site assessments installed 27, 1.5gpm
showerheads.
Agenda Item 22
Item # 22 Page 11
vi. By increasing water efficiency, we are decreasing the amount of energy used to heat
water. Natural gas comprises about 9% of the community’s carbon emissions or about
180,000 MTC02E. Most residential hot water heaters in Fort Collins are natural gas (about
90%) and most water use for showering is heated. A reduction in the showerhead flow
rate, in addition to reduced use of water from certain private commercial lavatory faucets
(also water that is frequently heated), help the City make progress towards its Climate
Action Plan goals and reaching carbon neutral by 2050. This is especially true since
natural gas use is more challenging to manage in a carbon neutral environment vs.
electricity which can be provided by solar and wind.
vii. Public comment included concern for changing flow rates and impacts to public health.
While no water distribution system in the world is sterile, Fort Collins Utilities takes
important steps in the water treatment process and in the distribution of drinking water to
customers to ensure its quality and safety. A key objective of the drinking water treatment
process is to remove turbidity, viruses and bacteria from the water supply to meet Federal
and State mandated water quality standards. Nitrate and Nitrite, which are a potential food
source for biofilms are also removed in the water treatment process. On average nitrate
concentrations leaving the water treatment facility are 0.04 mg/L and nitrite concentrations
are less than 0.04 mg/L, which are far below the EPA’s maximum contaminant levels for
safe drinking water of 10 mg/L and 1 mg/L, respectively.
1. In addition, Utilities track indicators of bacteria growth or contamination (e.g.,
heterotrophic plate count, E.coli, total coliforms) and free available chlorine (FAC)
concentrations on a weekly basis at 26 locations throughout the distribution
system to ensure that adequate disinfection is maintained as the water travels
from the treatment plant to the customer. This information is reported monthly to
the State of Colorado Department of Public Health and Environment to ensure
strict compliance. In 2017, the drinking water system was upgraded with a new
chlorine contact basin which provides more consistent levels of FAC throughout
the system. As a maintenance best practice, Utilities also flushes the entire
distribution system every two years.
2. Biofilms also occur within the premise plumbing systems of homes and buildings.
A chlorine residual above 0.2mg/L present at the point of use (e.g. faucet or
showerhead) is an indicator that bacteria originating from the premise plumbing
system are not likely a threat to the end user. Additional factors that influence
whether the residual exists at point of use, include frequency of use, water age
(increase in stagnation and increased risk for bacteria growth), temperature and
insulation of hot water line, and cleanliness of the fixture.
3. Researchers from Drexel, Penn State, and UC Boulder are examining risk factors
associated with reduced water use in building plumbing that could lead to bacterial
and chemical contamination. Staff spoke with lead researcher and professor,
Patrick Gurian, PhD, at Drexel University in October to discuss higher efficiency
fixtures and the potential for impacts. At the request of Staff, Dr. Gurian recently
updated the data to reflect a showerhead flow rate change from 2.0 to 1.8gpm. A
summary of the results is provided in a response from Dr. Gurian below:“A major
issue in maintaining water quality in building is the “water age”, that is how long
the water sits in the building pipes. We generally become concerned when the
water spends a long time in the pipes. Over a day or more the residual
disinfectant will decay, and microorganisms can grow, including some that are
opportunistic pathogens, such as Legionella. The lower flow showerhead would
not cause this situation. We calculate that even with the lower flow showerhead,
each shower would use on average 7-8 times the volume of a half-inch pipe. This
means that every time the shower is used freshwater is brought into the entire
length of the pipe. A single use of the shower “resets” the water age. Of course,
it’s really hard to say scientifically that the impacts are zero. There’s a lot we don’t
know about opportunistic pathogen growth and perhaps the small difference in the
flow rate of the water could conceivably have some impact, either positive or
negative, on microorganism growth. I think it’s appropriate to emphasize that
Agenda Item 22
Item # 22 Page 12
there’s no evidence for concern based on our knowledge. We found a case study
in EPA’s WaterSense in which a 1.75 gpm showerhead was adopted at the
Holiday Inn at the San Antonio Airport, indicating that this water conservation
measure can be implemented without evident adverse consequences.”
viii. Public comment referenced EPA approved studies on potential impacts of high-efficiency
fixtures on the presence and impact of biofilm. The early results referenced include
information gathered on only three unique “green” buildings and one “conventional”
residential home. This first glance focused on the increase in water age that is correlated
with increase in potential for bacteria growth. However, the concern is demonstrated
through a “net-zero” water building that stored and utilized large amounts of rainwater from
a 3,000-gallon cistern and groundwater to offset their low water demands. These
conditions do not exist in Fort Collins. Only residential homes can capture and store up to
110 gallons in rain barrels and must use the water only for landscape irrigation needs.
There is an emerging area of research, and Staff will continue to monitor prior to any
recommendations during the next Building Code Update cycle (expected in 2021).
ix. One option would be to amend the initial recommendations to exclude the showerhead
flow rate requirement from facilities that may have high risk or vulnerable populations, like
hospitals, care facilities, and educational facilities.
Options for City Council consideration
Based on additional research and outreach with stakeholders, staff proposes the following three options:
1. Approve the plumbing fixture changes as originally outlined in this adoption package.
2. Remove these fixture flow rate changes and keep the current flow rates as adopted in 2012.
3. Provide certain exemptions: (staff recommendation based additional research and input)
• Exempt I-occupancies (e.g., hospitals, assisted living facilities) and E-occupancies (e.g., K-12
schools, day care facilities) from the 1.8 gpm showerhead flow requirement, as these include
more vulnerable populations.
• Exempt I-occupancies (e.g., hospitals, assisted living facilities) in addition to the already
proposed R-occupancy (residential) exemption from the commercial private lavatory 0.5 gpm
requirement.
References (found in parentheses throughout document)
1. California currently has the same flow rate requirements as proposed. New York City has the same
flow rate requirements with the exception of the showerhead flow rate. Other states are pursuing
WaterSense requirements that also have 1.8 gpm showerhead requirements, including, Washington
and Massachusetts. Many rebate programs across the United States only rebate 1.1 gpf toilets with a
MaP score of 600 or greater (“MaP Premium”).

CITY FINANCIAL IMPACTS
Alterations to, or new construction of City-owned properties must comply with the provisions of the 2018 I-
Codes. The scope of work will determine the financial impact to the City. In general, there are no Citywide
financial impacts expected with the adoption of the 2018 I-Codes.
Community Development and Neighborhood Services (CDNS) anticipates the following financial impacts which
are accommodated by the current CDNS budget:
• Purchase of new building codes, approximately $5000. The necessary copies of the seven core 2018 I-
Codes will be purchased for staff.
• Staff training on the new codes is mostly accomplished in-house. When possible, staff will attend code
classes that are offered at various times throughout the year. This additional training cost is expected not
to exceed $5,000.
Triple Bottom Line Scan
The 2018 I-Codes adoption was not identified as one of the select major projects requiring a triple bottom line
scan.

City Code Update
Russ Hovland, Chief Building Official
(attachments available upon request)
Mr. Hovland presented the 2018 International Building Codes and International Residential Codes (IBC
and IRC, respectively) to the Energy Board in January; at the time staff was seeking support to bypass the
2018 IBC, which the board was supportive of. Mr. Hovland said staff has since identified a few issues
with bypassing 2018 updates: The 2015 Energy Policy commits to adopting codes within 12 months of
issuance; furthermore, if the City falls more than 12 months behind the code issuance, the Insurance
Services Office will downgrade the City’s rating which can affect homeowner’s insurance rates within the
City. Additionally, neighboring communities such has Longmont and Loveland are planning to move
ahead with the 2018 codes in January, and Fort Collins City staff do not want to fall too far behind.
The Code Review Committee met several times over the last few months and proposed a few
amendments to both the 2018 IBC and IRC. Mr. Hovland described the following amendments for the
board and added that staff’s cost assumptions (included in attachments) were determined after reaching
out to the tradespeople who would be involved with the code requirement such as electricians, plumbers,
mechanical contractors, and fire-suppression contractors. Construction supply houses were contacted for
an estimate of off-the-shelf materials.
The proposed amendments to the 2018 IBC include: In new commercial and multi-family buildings when
a trash chute is provided as typical in a multi-story apartment building, a second chute for recycling must
be provided. In new multi-family buildings 10% of all parking spaces must provide a conduit from the
electrical room to the front of the parking space for the purpose installing electric vehicle charging
equipment in the future. A new no-fee emergency repair permit provision was added to allow a permit to
be issued quickly in a disaster/damage situation where a building owner can temporarily repair a building
(house) to allow occupancy while more permanent repairs are forthcoming. This was recommended by
the county building department who scrambled to put this in place after several recent disasters.
The proposed amendments to the 2018 IRC include: New homes are to be provided with an empty ¾”
conduit from the attic to the main electrical panel for ease of installing future photovoltaic (PV) system
signaling wiring. New homes are to be provided with an empty ¾” conduit from the main electrical panel
board to an empty junction box in the garage for ease of installing future electrical vehicle (EV) charging
outlet. Window u-value (the rate of heath loss) will go change from .32 to .30 an increase in efficiency
and approximate cost increase of 8% for vinyl windows.

Excerpt from minutes
Energy Board Minutes
DRAFT October 11, 2018
Board members discussed the lack of Electric Vehicle Readiness in new commercial buildings, as
outlined for the multi-family amendment. Mr. Hovland said there was an issue around who would be
using those spaces (depending on the use of the building), like building employees versus customers, and
because of that the review committee elected to only amend the code for multi-family buildings. Board
members expressed their disappointment and said that much like solar-ready rooftops, the code does not
require the installation of the panels, only the infrastructure, and they believe the same methodology
should be put place for EV readiness. Mr. Hovland said if the Board is recommends including commercial
EV Readiness in the amendments, he would bring that feedback to the code review committee prior to
taking this item to City Council.
Board member Fassler said the building code is week, and for an organization with lofty Climate Action
Plan goals we should be striving to exceed the current standards; he disagrees with the review
committee’s amendment to allow existing construction to use a less efficient window u-value. Mr.
Hovland said the builders were concerned with home renovations, but board members felt that the
builders are not being ambitious enough because the cost will be passed onto the consumer regardless.
Board member Fassler moved to recommend the adoption of the 2018 International Codes and
References, with any necessary local amendments, except the allowance of a .32 window u-value for
existing homes.
Chairperson Michell proposed a friendly amendment, to recommend the adoption of the 2018
International Codes and References, with any necessary local amendments, except the allowance
of a .32 window u-value for existing homes, and include an amendment requiring commercial
new-construction to install EV readiness infrastructure.
Board member Becker would like to include an additional friendly amendment, the Energy
Board regrets the 2018 International Codes and References are insufficiently ambitious to
meet the City’s Climate Action Plan goals. The Board recommends the adoption of the
codes with any necessary local amendments; however, they also recommend striking the
allowance of a .32 window u-value for existing homes and would like the amendments to
include a provision requiring commercial new-construction to install EV readiness
infrastructure.
The proposed friendly amendments were accepted by the Energy Board.
Board member Becker seconded the motion.
Discussion:
Vice Chairperson Shores asked what the harm would be to vote no, since the Board has so many
stipulations. Chairperson Michell said a no-vote could be misconstrued as a vote to not update the codes
at all, which is not what the Board wants either. Mr. Hovland said a very similar situation happened when
they presented the codes to the Water Board, and they ultimately voted to approve the 2018 codes on the
condition that staff went back to the review committee to discuss the Board’s amendments. Mr. Hovland
said he would do the same for the Energy Board.
Vote on the Motion: It passed, 7-2
Vice Chairperson Shores said the codes are not ambitious enough. Board member Becker agreed, a yes
vote with all the conditional reasoning is not enough. He added that he voted no after Mr. Hovland’s last
presentation in January.

requirement will be for garages or surface lots, Whether the requirement will
change the width of spaces, How the EV ready framework will transform to
EV service, Whether or not the residential code acknowledge battery storage
for the future, What impact of multifamily EV spaces will have on affordability,
What does the window efficiency requirement buy you, If there isn't a change
in efficiency, why wouldn't we wait for a better product that can really change
the impact, Daycare facilities impact with local changes, When considering
code impacts, do we look at the large picture, Update on the process and
timeliness of permits, Do you bring in other boards to see impact and is there
any consideration of regionalizing codes and expectations?

B. 2018 International Building Code Updates—Russ Hovland, Chief Building Official
Going to council December 4 to propose adoption of updates to codes. Started review
committee in June and met for three months. Builders, architects, developers, City staff,
firefighters, etc. Suggested changes to code and then conducted outreach—take concerns
back to committee to address.
Comments/Q&A:
• Curt: Can you give a quick overview of changes?
o Russ: Changes between 2015-2018 code as written were very minimal. The
fewest I’ve seen in 15 years. We can delete the local amendments because they
are now included right in the code—able to delete about a third of the 200 pages
of local amendments.
• Jeff: There was a perfect match between local and international code?
o Russ: Yes. One example is radon: there were a couple things in our amendment
that weren’t in the code body.
o Jeff: How did you get it so right?
o Russ: We had a lot of really intelligent people, especially in the Utilities
Department, who all got together about what they foresaw for the future. A lot
was energy code based, radon, air quality. Brought this to us and we made
those local amendments.
• Rachel: What if the code changes in the middle of a project?
o Russ: You are vested at the time you apply for your permit.
• Sue: Are there new local amendments?
ATTACHMENT 8
AFFORDABLE HOUSING BOARD
REGULAR MEETING
10/11/2018 – MINUTES Page 2
o Russ: Yes, a couple new ones. For multifamily—the trash chute must have a
paired recycling chute. Unless these are side-by-side, recyclables tend to get
landfilled. That’s an approximate cost increase of $1,500 per floor. Another
amendment is in multifamily: 10% of parking spaces must provide an empty
electrical conduit for installing EV charging equipment in the future. About $300
per parking space.
o Sue: Could this be waved if there’s an affordable housing developer? For
example, Oakridge got their parking space reduced after some studies on
seniors who have vehicles. What if there’s a community that says we don’t
foresee our population using it?
o Russ: Council would have to approve that. It’s problematic when we wave
something for someone and then others want that as well. The one thing on this
requirement is that the goal is to eventually reduce costs. In the next 10 years,
we imagine EV prices going way down and these projects will already have the
infrastructure in place.
o Jen: It’s more expensive to retrofit after construction?
o Russ: Yes, retrofitting is very expensive. We landed on 10% of parking spaces
based on research: Aspen is doing 3%, Atlanta 20%, Boulder 10%.
• Russ: There’s a new emergency no-fee permit. For example, after a flood, very quick
free permits are needed. Adding that to the administrative part of the code.
• Russ: For single family homes, change in requirement of window efficiency. Changing
from .32 to .30 U value, slight increase in energy efficiency. Increase in cost per window
by about 8%. $200-$300 total for whole house window replacement.
o Jen: Is there much production of windows that don’t meet these values?
o Russ: Yes, but there are tons of windows that do meet this requirement and
better. They’re readily available.
• Sue: In your outreach, have people voiced concerns?
o Russ: Yeah, a couple. Chamber of Commerce had a concern about people
choosing to have an in-home daycare. By code and state law, allowed to have 5
kids, and when you have up to 5, that home does not change occupancy.
Doesn’t change to commercial daycare, not a lot of regulations. State regulated
and not locally regulated. Threw a requirement in the code that they have to fire
sprinkler the house, and this will start to impact a lot of people. Went into that
code section and struck out sprinkler requirement completely—is there any loss
of safety here? Not really. Reviewed this with the fire department and decided it
didn’t decrease safety for these homes to be without fire sprinklers.
o Russ: The Water Board wanted lower flow on shower heads and a fix to the toilet
requirement. The toilet flushing performance is called a map score –the higher,
the better. If you raise the map score, fewer flushes leads to lower water
consumption. Increased from 300 to 600 map score requirement.

10/11/2018 – MINUTES Page 3
o Russ: We were considering removing the U value requirement for windows, and
the Energy Board wanted to keep it.
Catherine: What happens if you don’t have vinyl windows? Like in my old
house from the 1800s.
Curt: This would be for new construction.
Catherine: What if I add an addition to an older house?
Russ: If someone is doing an addition in Old Town and they want to
match the windows, they may not be able to get the U value, and they can
come to the City for a variance.
• Sue: Would you welcome a recommendation from this board, or what would be helpful?
o Russ: Just a general agreement/vote that you support me taking these to
Council for adoption in December.
• Jen: Were any codes removed?
o Russ: Yes, there are occasionally codes removed. When you replace a water
heater, we used to require a combustion safety test to make sure it’s safe. The
problem is now that the homeowner wants to do their own water heater
replacement and has to pay to get the tests done, what we found is that people
stopped getting permits for water heaters. We analyzed whether or not the code
was serving its purpose, and decided no. We still do an inspection, we just no
longer require a combustion safety test.
• Curt: Doing the math on adding EV spaces to housing developments, it doesn’t seem
like enough to cause a big issue.
o Russ: And I think we can get those costs down, that’s the high-end, worst-case
scenario price at $300/space.
o Curt: For individual homeowners, there was already a requirement for the
conduit.
o Russ: Yes, just the size of the conduit increased.
Jen moved to support the internal building code update amendments.
Rachel seconded. Motion passed unanimously 5-0-0.

2. UPDATES TO 2015 BUILDING ORDINANCE
Russ Hovland, Department Head Building Services met with the NRAB to secure support for the
2018 updates to the Building Code. He explained that updates to the code occur every 3 years.
The particular updates to highlight for this evening’s discussion concern waste recycling, electric
vehicles, and emergency repair permits in disaster. These changes, he points out, are minimal.
Specifically, the change regarding recyclable materials requires multi-story, multi-family buildings to
have an additional disposal option for recyclable materials in addition to regular waste receptacles.
He points out that many builders already do this, thus, the impact is minimal.
Also proposed for the buildings are 10% EV Ready conduits for future Electric Vehicle charging
stations. Similar ordinances already exist for single family homes. There is an upgrade as well from
½” to ¾” conduits because electric vehicles require the upgrade.
Speaking for the NRAB, Luke Caldwell told Russ that the members feel the ordinance changes are
appropriate and want to record their support therefore.

3. 2018 I-CODES ADOPTION
Staff Report
Mr. Hovland presented the staff report and discussed each International Code being adopted. He noted
the 2015 Codes were adopted late, in 2017, and the goal is to implement a regular adoption schedule
every three years and to adopt the new Codes within 12 months of issuance.
Building Review Board
ATTACHMENT 10
DRAFT EXCERPT
City of Fort Collins Page 2 October 25, 2018
Advantages of this schedule will be to minimize the impacts of changes and lessen the degree of
construction cost increases as well as lessen ISO insurance rates.
Mr. Hovland discussed the process involved in examining the Codes for adoption, which began with
the formation of a committee of staff and stakeholders to review the Codes and local amendments. He
noted many of the local amendments are now in the Code which allowed about 1/3 of local amendments
to be deleted.
Mr. Hovland highlighted some proposed local amendments to the Codes. For the International Building
Code IBC, an amendment is planned to require a recycling chute next to any provided trash chute in
multi-story, multi-family buildings.
Additionally, for multi-family buildings, 10% of parking spaces must have a conduit from the electrical
room to the front of the parking space for the purpose of installing electric vehicle charging equipment
in the future. Mr. Johnson expressed concern about the requirement causing a spider web effect in a
small space. Mr. Hovland replied the Committee left flexibility on how the goal is achieved.
Mr. Hovland stated an emergency no-fee repair permit for disasters will be added to the IBC as well.
Mr. Hovland discussed minimal changes to the International Residential Code.
Mr. Hovland went on to discuss changes resulting from yesterday's final Committee meeting, one of
which involved sprinkler requirements for in-home daycares of 5 or less children. The City does not
receive notification of daycares as they are state regulated facilities; therefore, staff worked with Fire
Chief Poncelow to remove the requirement as the home is not changing occupancy and there are 5 or
less children. Mr. Reider expressed support for the change and Mr. Hovland noted there are other
state fire requirements for such daycares.
Mr. Hovland stated City Council has asked about roof shingle waste over the last few years given the
number of hail storms. Staff found construction materials, including shingles, make up 50% of landfill
materials and there is no place for shingle recycling in Northern Colorado. The Committee discussed
impact-resistant shingles at its meeting yesterday and ultimately voted to bring a local amendment to
require class four impact-resistant shingles for all asphalt roofs. Mr. Hovland noted the class four
shingles would likely still be destroyed in very severe hail storms with larger than golf ball size hail.
Mr. Reider expressed support for this amendment and asked if a re-roof would also require the class
four shingles. Mr. Hovland replied in the affirmative.
Mr. Reider mentioned homeowner's insurance policies can include riders for Code updates which would
enable homeowners to get replacement class four shingles. He suggested staff notify area insurance
agents.
Mr. Massey asked for more detail about class four shingles. Mr. Hovland described the testing process
and stated there are two types of class four shingles, one with a rubber backing and one with a
fiberglass backing. The rubberized-backed shingles have been found to be much more storm resistant.
Mr. Massey asked if it is assumed an older roof structure could handle the weight of class four shingles.
Mr. Hovland replied the Committee did not examine the potential weight of the shingles but stated older
buildings with 2x4 rafters may need to be examined. He noted there is currently no requirement for a
structural analysis unless the roof is concrete tile.
Ms. Penning expressed concern with imposing the requirement on older homes. Mr. Hovland replied
he would be more concerned with the weight issue if roofs were getting an overlay. He noted the
current Code only allows two layers and suggested language could be added to the amendment to
require structural evaluation if an overlay is planned.
Mr. Hovland stated the next local amendment is to change the showerhead flow rate from 2.0 gallons
per minute to 1.8 to lower water consumption. The estimate for water savings at total City build-out is
1.8 million gallons per year. Mr. Reider asked if the Committee considered longer shower use if the
flow is decreased. Mr. Hovland replied the Committee ultimately felt the savings was still worth the
change and stated the amendment can be reversed in three years if it is found to be an issue.
Mr. Hovland noted water conservation staff wanted to require low-flow toilets as well; however, the cast
iron and clay sewer systems do not allow waste to get to the main sewer line with these low-flow toilets.
Instead, staff opted to require increased MaP scores, which provide an indication of flush performance.
DRAFT EXCERPT
City of Fort Collins Page 3 October 25, 2018
Mr. Reider asked if the City has any plans to research the regulation of flushable wipes. Mr. Hovland
replied that issue will be examined over the next three years prior to the next Code cycle.
Mr. Hovland stated the last local amendment was a request from the Commission on Disability involving
an increase to the 30" width required for roll-in showers in multi-family buildings. The Commission
requested an increase from 30" x 60" to 36" x 60" minimum.
Mr. Marzonie asked about the number of accessible units required in multi-family buildings. Mr.
Hovland replied buildings of 26 units must provide one roll-in shower, 55 or 56 units must provide a
second, etc. The number of showers required will not change as part of this amendment.
Mr. Hovland reviewed the timeline for adoption of the Code changes.
Public Input
No members of the public were present.
Board Questions and Discussion
There was no further discussion.
Board Deliberation
Mr. Massey moved that the Building Review Board recommend the City adopt the 2018
International Codes with the local amendments as discussed.
Mr. Reider seconded. Motion passed 5:0.

Public Comment Summary
Staff met with 3 representatives at WaterPik
Main Concerns:
• Poor customer experience and will generate more complaints
• Dissatisfaction will lead to removing regulator and using more water
• Potential health issues resulting from lower flow rates
Staff spoke with 1 representative at Kohler
Main Concerns:
• 600 MaP is excessive – 350 MaP is sufficient.
• Focus on bulk waste may result in higher performance, but at the
sacrifice of light waste performance.
11
Availability and Cost
Staff research on toilets and showerheads:
- Local retailers (online and in-store)
- WaterSense product search - 1.8 vs. 2.0 gpm
- MaP product search - 600 vs. 350 grams
Results: No cost or availability impact. The Building Code Review
Committee independently verified this as well.
12
Options for Council’s Consideration
1. Approve the plumbing fixtures as originally outlined in this adoption
package.
2. Remove the fixture flow rate changes and keep the current rates, as
adopted in 2012.
a) Keep GPF determination for dual flush
b) Keep WaterSense requirements and exemptions for fixtures and fittings not
labeled under WaterSense’s program
3. Include an exemption for the showerhead flow requirement for the
following occupancy types:
a) I-occupancies (e.g. hospitals and assisted living facilities)
b) E-occupancies (e.g. K-12 schools and daycare facilities)

Plumbing Code Changes - Objectives
Supported by the Water
Efficiency Plan: “Encourage
greater integration of water
efficiency into land use planning
and building codes” is a
prioritized “Area of Opportunity” in
the Water Efficiency Plan (adopted
by Council in March 2016)
16
Opportunity for cost-
effective water savings
Desire to lead by doing
more than the minimum
Improve performance
Maximum Performance (MaP) Score
What is MaP?:
• “…represents the number of grams of solid waste (soybean paste and
toilet paper) that a particular toilet can flush and remove completely from
the fixture in a SINGLE FLUSH”
• Independent testing program – not affiliated with manufacturer
• Tested over 4800 toilets since 2003
• US EPA’s WaterSense program uses MaP score to determine WaterSense
eligibility
• Home Depot lists MaP Scores
17
MaP Score - Objectives
• Created to help consumers identify
performance, beyond pass/fail of
minimum certification requirements
• Minimize negative perception of
high efficiency toilets – multiple
flushes is a result of poor
performance, not high efficiency.
18
Does GPM affect showering time?
2005 AWE study found no change in shower duration
2017 Study based on the 1999 and 2016 Residential End Uses of Water
Studies:
• Increased shower length of 2 seconds resulted from 0.2 reduction in
gpm
• Water savings of 1.44 gallons per shower
19
Showerhead Performance and Experience
• WaterSense Label certifies 2 things: efficiency and performance
• Larimer County Conservation Corp: 1.5 gpm
• 1,000s installed over the years
• Follow up study showed households overwhelmingly kept all fixtures
• Xcel Multi-Family Program: 1.5 gpm showerheads
• Efficiency Works commercial site assessments: 1.5 gpm showerheads
• Water Conservation’s rebate program: 1.5 gpm
• Utilities’ Peak Partners installed 1230 showerheads:
• 1.5 gpm showerheads installed
• 6.15 MG/year saved

Other Benefits
Saves Utility and Customers money
• Reduce Utilities’ need to provide future funding for rebate
programs
• Saves customer:
• cost of fixture now and upgrades later
• water and heating bill expenses
Progress towards CAP goal – carbon neutral by 2050:
• Almost all shower water is heated water
• Lavatory faucet water is typically heated too
22
Other Benefits
Promotes water efficiency in other water districts too
Aligns with Colorado’s Water Plan:
• “Reduce overall future water needs through cost-effective
water efficiency measures” (pg. 59)
• “Explore legislative options and support for indoor
plumbing-code standards” (pg. 66)
23
Other Examples
Denver’s New Construction Program Requirements (for reduced fees):
• Toilets: Tank type toilets (including pressure assist)
1.1 gpf or less
• Urinals: 0.125 gpf or less (Water Sense Labeled)
• Kitchen Faucets: 1.5 gpm or less
• Lavatory Faucets: 0.5 gpm and pressure compensating
• Showerheads: 1.75 gpm or less (Water Sense
