SUBJECT
Second Reading of Ordinance No. 114, 2018, Amending Article 3 of the Land Use Code Regarding Buffering
Requirements for Development in Relation to Oil and Gas Facility Locations.
EXECUTIVE SUMMARY
This Ordinance, unanimously adopted on First Reading on August 21, 2018, amends the Land Use Code related
to buffering new development from existing oil and gas wells. The amendments include the following Code
changes:
1. Increase buffer for residential development near existing oil and gas operations from 350 feet to 500 feet.
2. Add a new 1000-foot buffer requirement for high occupancy buildings near oil and gas operations.
3. Allow a reduced setback (150 feet minimum) near plugged and abandoned wells if specific requirements
and performance standards are met.
4. Create an additional means of disclosure to future property owners as part of any required recorded
declaration.
Staff proposes additional language relating the measurement of buffers around oil and gas wells. Based on new
information received between first and second reading from the Colorado Oil and Gas Conservation Commission
(COGCC), staff determined that an additional revision would be necessary to align the proposed ordinance with
the original intent for the code changes, which was to match any changes to COGCC regulations that would
result in more protective buffers.
STAFF RECOMMENDATION
Staff recommends adoption of the Ordinance on Second Reading.

EXECUTIVE SUMMARY
The purpose of this item is to present Land Use Code updates related to buffering new development from existing
oil and gas wells for Council consideration. The staff recommendation includes the following Code changes:
1. Increase buffer for residential development near existing oil and gas operations from 350 feet to 500 feet.
2. Add a new 1000-foot buffer requirement for high occupancy buildings near oil and gas operations.
3. Allow a reduced setback (150 feet minimum) near plugged and abandoned wells if specific requirements
and performance standards are met.
4. Create an additional means of disclosure to future property owners as part of any required recorded
declaration.
STAFF RECOMMENDATION
Staff recommends adoption of the Ordinance on First Reading.
BACKGROUND / DISCUSSION
Purpose and Intent
Staff initiated a review of the current oil and gas buffers with a goal of ensuring that Land Use Code (LUC)
regulations will continue to protect the health and safety of Fort Collins residents and provide predictability for
developers into the future.
The intent of the proposed changes is to match or exceed Colorado Oil and Gas Conservation Commission
(COGCC) requirements, ensure the safest possible condition for current and future residents, incentivize the
plugging and abandonment of active wells, and support additional investigation of plugged and abandoned wells.
The following goals guided staff’s analysis:
1. Increase the required buffers for new development around existing oil and gas operations to provide greater
protection to residents and improve consistency with state regulations;
2. Allow consideration of reduced buffers around plugged and abandoned wells if the surrounding area has
been deemed safe for development;
3. Facilitate site investigation and sampling around plugged wells, at a developer’s expense; and
ATTACHMENT 1
Agenda Item 24
Item # 24 Page 2
4. Encourage developers to permanently plug and abandon active wells rather than keeping wells in operation
near residential development.
Summary of Proposed Land Use Code Updates
The current staff recommendation includes the following Code changes:
1. Increase buffer for residential development near existing oil and gas operations from 350 feet to 500 feet.
2. Add a new 1000-foot buffer requirement for high occupancy buildings near oil and gas operations.
3. Allow a reduced setback (150 feet minimum) near plugged and abandoned wells if specific requirements
and performance standards are met.
4. Create an additional means of disclosure to future property owners as part of any required recorded
declaration.
The initial staff recommendation was modified based on input from the general public, landowners and other
stakeholders, and boards and commissions. The full set of proposed changes is included in Attachment 1.
Follow-up from City Council Work Session
Staff presented the proposed Land Use Code updates at the June 19, 2018, Work Session. Council was
generally supportive of the proposed Land Use Code changes and appreciated the amount and type of outreach
conducted by staff. Questions and discussion focused on the level of risk associated with plugged and
abandoned wells, as well as how various requirements and thresholds had been determined, including the
minimum 150-foot buffer around plugged and abandoned wells. Based on Council’s direction, staff followed up
on a number of questions and comments described in more detail in this agenda item summary.
Current Oil and Gas Operations in Fort Collins
The Fort Collins Growth Management Area (GMA) contains 16 active wells (all operated by Prospect Energy)
and 30 wells that have been abandoned. Prospect Energy’s operations in the Fort Collins Field are limited to oil
production; no natural gas is extracted or produced within the GMA. The Fort Collins Field consists of
unpressurized oil that is bonded to bedrock. Water pressure is used to force oil upward, and the resulting product
is approximately 97% water and 3% oil, with almost no associated gas.
Unlike natural gas operations in other communities along the Front Range, continuous flaring does not occur at
the Fort Collins wells, as there is little to no gas that would need to be flared. There is little possibility for methane
to migrate upward from the formation for either active or abandoned wells.
Abandoned wells in Fort Collins vary significantly in age, with some wells abandoned as far back as the 1920s
and others abandoned within the last year. As such, the amount and precision of information about these wells
(e.g., exact locations or details about how they were plugged) also varies. Unknown or undiscovered wells in the
Fort Collins Field are very unlikely given the low levels of production that have occurred in this field over the past
century.
Oil and Gas Buffers
The COGCC regulates permitting and setbacks for new wells near existing buildings but does not regulate the
reverse situation: permitting and setbacks for new development near existing oil and gas infrastructure. The
Land Use Code currently requires a buffer of at least 350 feet between existing oil and gas operations (both
active and abandoned) and new residential development.
The previously adopted 350-foot buffer was specifically intended to match the COGCC setback requirements for
new wells, which were 350 feet at the time of adoption. Since then, the COGCC has updated its setbacks for
new oil and gas wells to 500 feet. COGCC further distinguishes between general residential development and
land uses deemed to be “high occupancy,” which includes certain schools, hospitals, nursing homes, correctional
facilities, and daycare centers. The state requires a setback of 1,000 feet between these uses and new wells.
Agenda Item 24
Item # 24 Page 3
Staff recommends updating the City’s buffer requirements to 500 feet for residential development and 1,000 feet
for high occupancy uses, consistent with current state-level regulation and City Council’s previous direction. The
code changes also include a clause that would automatically increase the required buffer if state requirements
also increase in the future.
Plugged and Abandoned Wells and Associated Risks
Plugged and abandoned wells have been permanently removed from production and filled with a combination
of concrete plugs, slurries, and other materials. Many of the older wells in Fort Collins were abandoned prior to
current regulations and state oversight. As such, there is uncertainty about if, when, and how the wells were
plugged, and it is possible that some of these wells would not meet the current COGCC standards. Risks related
to plugged and abandoned wells are very difficult to quantify, as it is highly dependent on site-specific conditions,
production type, well construction details, plugging and abandonment techniques, and age of wells. Staff has
been unable to find research documenting failure rates or contamination risks for wells with the same
combination of production type, well age, and site conditions present in the Fort Collins Field. It is possible that
the integrity of wells plugged many decades ago has changed as they have aged. While there have been no
known issues with any abandoned wells in Fort Collins, there have been documented safety incidents related to
old, improperly plugged wells in other communities, primarily in natural gas fields that differ significantly from the
Fort Collins Field.
It is in the community’s interest to understand the existing conditions, and therefore potential risks, related to the
various abandoned wells throughout the city. The Land Use Code does not distinguish between operational
(active) wells and wells that have been plugged and abandoned. However, wells that have been abandoned to
current state standards have a much lower potential for environmental contamination, public health impacts, and
public safety incidents. Further, well sites in Fort Collins have a comparatively lower risk of methane leaks, as
no natural gas is produced from the Fort Collins Field. As such, a reduced setback may be appropriate in
situations where the City can verify that wells have been properly plugged and no leaks or contamination have
occurred.
In addition, a reduced setback for properly abandoned wells would create a stronger incentive for land
developers to coordinate the abandonment of active wells on development sites, rather than keeping wells in
operation as new development occurs. Allowing a reduced setback would encourage the developer to work with
an oil and gas operator to remove the well from operation, therefore significantly reducing public health and
safety risks near future residential properties.
There was a question at the City Council work session related to the impact of expansive soils and other
geotechnical conditions on the long-term integrity of plugged and abandoned wells. Staff has discussed this
concern with a qualified geotechnical engineer, who stated that the risk for expansive soils impacting a plugged
and abandoned well is very low. Expansive soils only expand and contract when moisture is added, which
typically only occurs as a result of heavy irrigation (e.g., for turf landscaping). The maximum “wetting depth” for
heavily irrigated areas is 15 to 20 feet of soil. Even in the event that there are irrigated, expansive soils around
a plugged and abandoned well, there is a low likelihood that the soils could put enough pressure on a concrete
well casing to cause a barrier failure.
Alternative Compliance Option
Staff recommends an alternative compliance option that would allow for a reduced buffer (150 foot minimum) if
the City can verify that plugging and abandonment have occurred in accordance with current COGCC standards
and no contamination is present on a site. A buffer of 150 feet would provide adequate space for equipment to
replug or maintain a permanently plugged well in the future, if needed. The following sampling and monitoring
measures would be required to determine whether alternative compliance would be appropriate. The required
measures replicate the sampling methods used in Longmont to document the condition of plugged and
abandoned wells in that community:
Agenda Item 24
Item # 24 Page 4
1. Site survey, historical research and/or physical locating techniques to determine exact location and extent
of oil and gas operations and facilities.
2. Documentation of plugging activities, abandonment and any subsequent inspections.
3. Soil sampling, including soil gas testing.
4. Groundwater sampling.
5. Installation of permanent groundwater wells for future site investigations or monitoring.
6. Additional requirements as determined by staff and/or the decision-maker.
The following verification and performance standards would need to be satisfied for a reduced buffer to be
approved:
1. Written report verifying that the soil and groundwater samples meet applicable EPA and State residential
regulations.
2. Verification that a reduced buffer would not pose a greater health or safety risk for future residents or users
of the site than baseline site conditions.
3. Remediation of environmental contamination to background levels, if necessary.
4. Well repair or replugging of a previously abandoned well, if necessary.
Disclosure to Future Property Owners
The Land Use Code currently requires notification about oil and gas wells to be placed on the plat for a new
subdivision. Based on feedback from boards and the public, staff determined that this method of notification may
be easily overlooked by a future homebuyer, so an additional method of notification is appropriate. Staff
recommends a requirement that developers include information about any existing oil and gas wells as part of
any recorded declaration required under the Colorado Common Interest Ownership Act for all properties within
1000 feet of any wells. This information would be more readily available to all future property owners.
CITY FINANCIAL IMPACTS
Adoption of these Code changes will not have a significant impact on City resources. Additional staff time may
be required to review alternative compliance requests for plugged and abandoned wells; however, this is
comparable to the amount of time staff already dedicates to environmental concerns on various development
projects.
BOARD / COMMISSION RECOMMENDATION
Staff held extensive discussions with the Planning and Zoning Board (3 work sessions and 2 hearings), Natural
Resources Advisory Board (3 meetings) and Air Quality Advisory Board (4 meetings) over the past nine months.
All three boards have provided recommendations on the currently proposed changes. The staff recommendation
and three board recommendations are summarized in Table 1 below.
A follow-up meeting was held with members of each board on June 4, 2018. The purpose of this meeting was
to confirm understanding of the proposed code changes and clarify the recommendations of each board. The
boards all support increased buffers around active wells, and they also share concerns about uncertainty and
lack of data for older plugged and abandoned wells. There was discussion, but not consensus, about the
measurement of buffers (i.e., to a property line rather than the nearest occupied building). All three boards felt
that more stringent monitoring and accountability requirements should be applied if reduced buffers will be
considered.
Based on public input and board recommendations, staff made the following modifications to the proposed Code
changes:
Do not allow parks, playgrounds, recreational fields or community gathering spaces to be placed within a
buffer, both for residential and high occupancy uses
Require a minimum of five years of annual monitoring of plugged and abandoned wells (if a reduced buffer
is granted)
Agenda Item 24
Item # 24 Page 5
Require a certification that the site is free from contamination and is safe for residential use (if a reduced
buffer is granted)
Require remediation of any environmental contamination, repair of a damaged well, or re-plugging of a well
if determined to be necessary (if a reduced buffer is granted)

ORDINANCE NO. 114, 2018
OF THE COUNCIL OF THE CITY OF FORT COLLINS
AMENDING ARTICLE 3 OF THE LAND USE CODE REGARDING BUFFERING
REQUIREMENTS FOR DEVELOPMENT IN RELATION TO OIL AND GAS FACILITY
LOCATIONS
WHEREAS, on December 2, 1997, by its adoption of Ordinance No. 190, 1997, the City
Council enacted the Fort Collins Land Use Code (the "Land Use Code"); and
WHEREAS, at the time of the adoption of the Land Use Code, it was the understanding of
staff and the City Council that the Land Use Code would most likely be subject to future
amendments, not only for the purpose of clarification and correction of errors, but also for the
purpose of ensuring that the Land Use Code remains a dynamic document capable of responding
to issues identified by staff, other land use professionals and citizens of the City; and
WHEREAS, since its adoption, City staff and the Planning and Zoning Board have
continued to review the Land Use Code and identify and explore various issues related to the Land
Use Code and have now made new recommendations to the Council regarding certain issues that
are ripe for updating and improvement; and
WHEREAS, the proposed changes to the Residential Buffering Land Use Code
requirements are to ensure the health and safety of the residents of development in close proximity
to oil and gas facility locations; and
WHEREAS, the City Council has determined that the recommended Land Use Code
amendments are in the best interests of the City and its citizens.
NOW, THEREFORE, BE IT ORDAINED BY THE COUNCIL OF THE CITY OF FORT
COLLINS as follows:
Section 1. That the City Council hereby makes and adopts the determinations and
findings contained in the recitals set forth above.
Section 2. That Section 3.8.26 of the Land Use Code is hereby amended to read as
follows:
3.8.26 Buffering for Residential and High Occupancy Building Units
(A) Applicability. These standards apply only to applications that include residential
uses and, to the extent legally applicable, high occupancy building units. Standards
regarding Buffer Yard D shall not apply to any lot for which a site specific
development plan with vested rights was approved prior to September 14, 2018 so
long as such site specific development plan was, or is, valid at the time of issuance
of any building permit for the construction or modification of any dwelling unit or
high occupancy building unit on such lot.
-2-
(B) Purpose. The purpose of this Section is to provide standards to separate residential
land uses and high occupancy building units from existing industrial uses, in order
to eliminate or minimize potential nuisances such as dirt, litter, noise, glare of lights
and unsightly buildings or parking areas, or to provide spacing to reduce adverse
impacts of noise, odor, air pollutants, hazardous materials or site contamination, or
danger from fires or explosions.
(C) Buffer standards. Buffer yards shall be located on the outer perimeter of a lot or
parcel and may be required along all property lines for buffering purposes and shall
meet the standards as provided in this Section.
(1) Only those structures used for buffering and/or screening purposes shall be
located within a buffer yard. The buffer yard shall not include any paved
area, except for pedestrian sidewalks or paths or vehicular access drives
which may intersect the buffer yard at a point which is perpendicular to the
buffer yard and which shall be the minimum width necessary to provide
vehicular or pedestrian access. Fencing and/or walls used for buffer yard
purposes shall be solid, with at least seventy-five (75) percent opacity.
(2) There are four (4) types of buffer yards which are established according to
land use intensity as described in Chart 1 below. Buffer yard distances are
established in Chart 2 below and specify deciduous or coniferous plants
required per one hundred (100) linear feet along the affected property line,
on an average basis.
(3) The buffer yard requirements shall not apply to temporary or seasonal uses
or to properties that are separated by a major collector street, arterial street,
or highway.
(4) Additional Standards Applicable to Buffer Yard D. The following
requirements shall also apply to development located in Buffer Yard D:
(a) Measured. For purposes of Buffer Yard D standards, the buffer yard
shall be measured as either the distance from the outer edge of an
oil and gas location to the nearest wall or corner of any dwelling or
high occupancy building unit location or, if any Colorado Oil and
Gas Conservation Commission adopted setback measurement
method applicable to a dwelling or high occupancy building unit
results in a greater distance between the existing oil and gas
operation site location and the dwelling or high occupancy building
unit at issue, then the Colorado Oil and Gas Conservation
Commission setback measurement method shall be used. Buffer
Yard D areas may include paved areas, notwithstanding paragraph
(1) above.
-3-
(b) Minimum Buffer Distances. The following minimum buffer
distances shall apply:
1. Residential Development. The minimum buffer between a
dwelling and any oil and gas location shall be five hundred
(500) feet, or the Colorado Oil and Gas Conservation
Commission designated setback distance, whichever is
greater. Public playgrounds, parks, recreational fields, or
community gathering spaces shall not be placed within a
buffer. Private common areas within a buffer shall not
contain playgrounds, parks, recreational fields, or
community gathering spaces.
2. High Occupancy Building Units. The minimum buffer
between a high occupancy building unit and any oil and gas
location shall be one thousand (1,000) feet, or the Colorado
Oil and Gas Conservation Commission designated setback
distance, whichever is greater. Public or private
playgrounds, parks, recreational fields, or community
gathering spaces shall not be allowed within a buffer.
(c) Alternative compliance buffer reduction from plugged and
abandoned wells. Upon applicant request, the decision maker may
approve a reduced buffer distance from a plugged and abandoned
well for which reclamation has been completed, all of the
aforementioned in accordance with Colorado Oil and Gas
Conservation Commission regulations, in lieu of the minimum
buffer distances set forth in the immediately preceding Subsection
(b), provided that the approved reduced buffer is no less than 150
feet from the permanently abandoned well and meets the
requirements specified below.
1. Procedure. To request alternative compliance, an alternative
compliance buffer reduction plan shall be prepared and
submitted in accordance with the submittal requirements
established by the Director. At a minimum, the plan must:
a. Clearly identify and discuss the proposed buffer
reduction and the ways in which the plan will equally
well or better eliminate or minimize the nuisances
and reduce the adverse effects referenced in the
purpose of this Section than would a plan which
complies with the separation and spacing standards
of this Section.
-4-
b. Include information regarding environmental testing
and monitoring for the site. Site investigation,
sampling, and monitoring shall be conducted to
demonstrate that the well has been properly
abandoned and that soil, air and water quality have
not been adversely impacted by oil and gas
operations or facilities or other sources of
contamination. Such sampling and monitoring shall
be conducted by a qualified environmental
engineering or consulting firm with experience in oil
and gas investigations. Director approval that the
sampling and monitoring plan contains the
information required pursuant to this subsection b) is
required prior to sampling occurring and such plan
shall include, but is not limited to, the following:
i. Site survey, historical research, and/or
physical locating techniques to determine
exact location and extent of oil and gas
operations and facilities.
ii. Documentation of plugging activities,
abandonment and any subsequent
inspections.
iii. Soil sampling, including soil gas testing.
iv. Groundwater sampling.
v. Installation of permanent groundwater wells
for future site investigations.
vi. A minimum of five (5) years of annual soil
gas and groundwater monitoring at the well
location.
c. Upon completion of the site investigation and
sampling, not including the ongoing monitoring, the
consultant must provide a written report verifying
that the soil and groundwater samples meet
applicable EPA and State residential regulations and
that a reduced buffer would not pose a greater health
or safety risk for future residents or users of the site.
Otherwise, the decision maker may specify an
appropriate buffer distance or require that the
following actions be completed by a qualified
-5-
professional before development may occur,
including but not limited to:
i. Remediation of environmental
contamination to background levels.
ii. Well repair or re-plugging of a previously
abandoned well.
2. Review Criteria. To approve an alternative compliance
buffer reduction plan, the decision maker must first find that
the proposed alternative plan eliminates or minimizes the
nuisances and reduces the adverse effects referenced in the
purpose of this Section equally well or better than would a
plan which complies with the separation and spacing
standards of this Section. An approved alternative
compliance buffer reduction plan shall be exempt from the
screening requirements of Chart 2 – Buffer Yard Types and
below Subsection (e) regarding fencing.
(d) Disclosure. If any residential development or dwelling, or high
occupancy building unit is proposed to be located within one
thousand (1,000) feet of an oil and gas location, the following
requirements shall apply:
1. Aat such time as the property to be developed is platted or
replatted, the plat shall show the one-thousand-foot radius
on the property from such oil and gas location and shall
contain a note informing subsequent property owners that
certain lots shown on the plat are in close proximity to an
existing oil and gas location.
2. For residential developments requiring a declaration
pursuant to the Colorado Common Interest Ownership Act,
a statement shall be included in such declaration specifying
the lots within such residential development upon which
dwellings may be constructed that are within one thousand
(1,000) feet of an oil and gas location. The approved plat for
such residential development shall be attached to the
recorded declaration. Where no such declaration is required,
the property owner shall record a statement on the property
where the dwelling is located indicating that such property
is located within one thousand feet of an oil and gas location.
(e) Fencing. If any residential development is proposed to be located
within five hundred (500) feet of an oil and gas location, and if an
-6-
existing fence does not surround the oil and gas location, the
developer must erect a fence that restricts public access to the oil
and gas location along the property boundary between the oil and
gas location and the development.

Section 3. That Section 5.1.2 of the Land Use Code is hereby amended by the addition
of three new definitions which read in their entirety as follows:
High occupancy building unit shall mean any building type listed in the Colorado Oil and
Gas Conservation Commission definition of a High Occupancy Building Unit set forth in
the Code of Colorado Regulations.
Oil and gas facility shall mean equipment or improvements used or installed at an oil and
gas location for the exploration, production, withdrawal, gathering, treatment, or
processing of oil or natural gas. This term shall include equipment or improvements
associated with active, inactive, temporarily abandoned, and plugged and abandoned wells.
Oil and gas location shall mean: (1) the area where the operator of an oil and gas facility
has disturbed the land surface in order to locate an oil and gas facility or conduct oil and
gas operations, or both; or (2) the area where the operator of an oil and gas facility intends
to disturb the land surface in order to locate an oil and gas facility or conduct oil and gas
operations, or both, and such facility or operations have received all required permits prior
-8-
