ORDINANCE NO. DCA19-0009e
AN ORDINANCE OF THE CITY OF DENTON, TEXAS, AMENDING SUBCHAPTERS
1, 6, AND 8 OF THE DENTON DEVELOPMENT CODE, RELATING TO
APPLICABILITY, GAS WELL DRILLING AND PRODUCTION REVERSE SETBACKS,
DEFINITIONS, AND PROCEDURES; PROVIDING A CUMULATIVE CLAUSE;
PROVIDING A SEVERABILITY CLAUSE; PROVIDING FOR A PENALTY; AND
PROVIDING AN EFFECTIVE DATE.
WHEREAS, the City of Denton is a home-rule city acting under its Charter adopted by the
electorate pursuant to Article XI, Section 5 of the Texas Constitution and Chapter 9 of the Texas
Local Government Code, and accoqnngly enjoys broad powers of self-governance; and
WHEREAS, the City Council, pursuant to Ordinance No. 2001-465 adopted the City's first
gas well drilling and production regulations as part of Chapter 35, "Zoning," and adopted
Ordinance No. 2001-466 as part of Chapter 34, "Subdivision and Land Development," of the City
ofDenton Code of Ordinances (collectively referred to as the "Gas Well Ordinance"); and
WHEREAS, the Gas Well Ordinance has been amended a few times since its initial
adoption; and
WHEREAS, the most recent amendment of the Gas Well Ordinance occurred on August
4, 2015 (Ordinance No. 2015-233), so as to comply with House Bil140 (Texas Natural Resources
Code, Sec. 81.0523) (enacted May 18, 2015), which provides the State of Texas with exclusive
jurisdiction over Gas Well Drilling and Production Activities. Municipalities are preempted from
regulating such activities, except as allowed in Sec. 81.0523(c), which expressly provides that a
municipality has authority to regulate certain aspects of aboveground activity related to oil and gas
operations; and
WHEREAS, even after the adoption of Ordinance No. 2015-233, the City Council has
continued to receive from the public a multitude of land use compatibility concerns regarding the
City's ordinances and regulations applicable to the gas well drilling and production activities,
including, but not limited to, health, noise, lighting, truck traffic, dust, vibrations, and other
nuisances; and
WHEREAS, this has increased over the years as more and more residential subdivisions
and other Protected Uses have developed in proximity to existing gas well drilling and production
sites; and
WHEREAS, any future drilling in close proximity to residential and other Protected Uses
will result in negative and deleterious effects on Denton citizens, calling into question whether the
various interests could be better balanced by additional review of the City's ordinances and
regulations; and
WHEREAS, the City Council of the City of Denton has witnessed the conflict between
increased drilling and urban expansion, and acknowledges the need to regulate the conflicting land
Page 1 of4
S:\Legal\Our Documents\Ordinances\20\DCA19-0009 -Gas Well Amendments 500 Ft Reverse Setback.Docx
use issues between gas well operations and surface owners seeking the peaceful and quiet
enjoyment of their property; and
WHEREAS, the City Council finds that potentially harmful impacts of gas well drilling
and production within the City fall most heavily upon neighborhoods and properties adjacent to
gas well drilling and production operations, even where the adjoining properties are developed
subsequent to mineral estate development and gas well drilling/placement; and
WHEREAS, surface development of properties conducted within city limits are subject to
and governed by the City's zoning regulations and are not protected by House Bill40; and
WHEREAS, the City Council, after due and careful consideration, found that there remain
significant and compelling environmental and land use compatibility concerns associated with gas
well drilling and production activities and subsequent surface development on adjoining
properties; and
WHEREAS, as a response to these continuing concerns, on July 16, 2019, the City Council
held a work session on the current gas well setbacks and reverse setbacks and determined that the
reverse setbacks, which apply to Protected Uses should be increased; and
WHEREAS, the City Council determined that an increased gas well reverse setback of 500
feet is more protective in terms of health, noise, lighting, truck traffic, dust, vibrations, and other
nuisances based upon results of a natural gas air quality study conducted by the Eastern Research
Group for the City of Fort Worth, which is relatively similar to Denton in terms of geology and
topography and is located in the Barnett Shale; and
WHEREAS, on August 27, 2019, the City Council further considered the textual
amendments to be made to the Denton Development Code to implement the increased reverse
setbacks; and
WHEREAS, on November 6, 2019 the Planning and Zoning Commission held a public
hearing to hear testimony from citizens in connection with the proposed Gas Well Ordinance
amendments being considered; and
WHEREAS, on November 19, 2019, the City Council held a public hearing pursuant to
state law, to hear testimony from citizens in connection with the proposed Gas Well Ordinance
amendments as set forth in Ordinance DCA19-0009c; and
WHEREAS, at its regular meeting on November 19, 2019, the City Council, after due and
careful consideration, found that there remain significant and compelling land use compatibility
concerns associated with gas well drilling and production activities and subsequent surface
development on adjoining properties and adopted the Gas Well Ordinance amendments; and
WHEREAS, on December 2, 2019 the City Council, voted [5-2] to reconsider the approval
of the Gas Well Ordinance amendments; and
Page2 of4
S:\Legal\Our Documents\Ordinances\20\DCA19-0009 -Gas Well Amendments 500Ft Reverse Setback.Docx
WHEREAS, on January 28, 2020, the City Council conducted a public hearing pursuant to
state law to hear testimony from citizens in connection with the proposed Gas Well Ordinance
amendments; and
WHEREAS, upon reconsideration, the City Council, finds that there remain significant and
compelling land use compatibility concerns associated with gas well drilling and production
activities and subsequent surface development on adjoining properties; and
WHEREAS, the City Council further finds that the subject changes to the Denton
Development Code are consistent with the Comprehensive Plan and are in the public interest and
assure the health, safety, and general welfare of the City's residents and businesses; and
WHEREAS, the City Council additionally finds that the provisions of the amendatory
ordinance are in compliance with House Bill 40; NOW, THEREFORE,

Exhibit A4 –Subchapter 1 Amendments – Option 4
1.5 Nonconformities 1
1.5.1 Purpose 2
The purpose of Section 1.5 is to regulate and limit the development and continued existence of land, 3
buildings, structures, uses, and site features that were lawfully established prior to the effective date of 4
this DDC, but that no longer conform to the requirements of this DDC. All such situations are collectively 5
referred to in this section as “nonconformities.” While nonconformities may continue, the provisions of 6
this section are designed to curtail substantial investment in nonconformities to bring about their 7
eventual elimination in order to preserve the integrity of this DDC and the goals of the City of Denton. 8
1.5.2 Regulations Applicable to All Nonconformities 9
A. Authority to Continue 10
Nonconformities may continue to be used and occupied, subject to regulations as to the 11
maintenance of premises and conditions of operations set forth in this section, or unless such 12
nonconformity is terminated as provided in this section. 13
B. Determination of Nonconformity Status 14
The burden of establishing the existence of a nonconformity shall be solely on the owner of the 15
property containing the nonconformity. An applicant may use the procedure in Subsection 2.5.4, 16
Certificate of Zoning Compliance, to establish the existence of a nonconformity. 17
C. Maintenance and Minor Repair 18
Minor repairs and maintenance of nonconformities are permitted and encouraged, provided 19
that the repairs and maintenance do not increase the degree of nonconformity. Minor repairs 20
and maintenance include the following: 21
1. Repairs necessary to maintain and to correct any damage or deterioration to the 22
structural soundness of, or the exterior or interior appearance of, a building or structure 23
without expanding the height or footprint of the building or structure, unless compliant 24
with this DDC; 25
2. Maintenance of land to protect against and mitigate health and environmental 26
hazards; 27
3. Resurfacing or restriping parking areas (but no enlargement of parking area) 28
pursuant to Section 7.9, Parking and Loading; 29
4. Replacing diseased or dead plant materials pursuant to Section 7.7, 30
Landscaping, Screening, Buffering, and Fences; 31
5. Repairs that are required to remedy unsafe conditions; and 32
6. Repairs necessary to comply with current building code requirements. 33
D. Change of Ownership or Tenancy 34
Exhibit A4 –Subchapter 1 Amendments – Option 4
Changes in ownership, tenancy, or management of property with an existing nonconformity 35
may occur, but such nonconformities shall continue to be subject to the standards of this 36
Section 1.5. 37
E. Compliance to the Maximum Extent Practicable 38
Where compliance with the requirements of this section is precluded by a lack of sufficient 39
developable area due to the size of the lot, the layout of existing development, or the presence 40
of significant wetlands, floodplains, watercourses, hazard areas, or other significant 41
environmental constraints, the applicant shall comply with the requirements of this section to 42
the maximum extent practicable, as determined by the Director. 43
F. Discontinuance 44
1. Whenever a nonconforming use or structure is discontinued for one year or 45
more, all nonconforming rights shall cease, and the use of the premises or the structure 46
shall be in conformance with this Subchapter and all applicable codes of the City. For 47
purposes of this provision, the following actions shall create a rebuttable presumption 48
of discontinuance: the property or structure is vacant and no attempt to market the 49
property is observable on the property or from the exterior of any structure, or that the 50
property or structure is vacant and City taxes owed on the property are delinquent. The 51
determination of discontinued status may be delayed for up to one year by the Director 52
upon written request, if the applicant provides documentation that the property has 53
been actively marketed for at least six months during the previous, first year. 54
2. The right to maintain or operate a nonconforming structure or use may be 55
terminated by the Zoning Board of Adjustment in accordance with Subsection 1.5.8, 56
Amortization of Nonconforming Uses or Structures. Any appeal of the termination of 57
nonconforming rights by the Zoning Board of Adjustment under this Subchapter shall be 58
made to the District Court within 10 days of receipt of written notice of the termi nation 59
by the Director. 60
G. Nonconformity Due to Outside Action 61
1. Where a lot, tract, or parcel is occupied by a lawful structure, and where the 62
acquisition of right-of-way, by eminent domain, dedication, or purchase, by a city, 63
county, state, or federal agency creates noncompliance of the structure or property 64
regarding any requirement of this DDC, such structure or property shall be deemed 65
nonconforming, and acquiring agency shall provide a compliance plan. Such designation 66
shall apply only to noncompliance that results directly from the acquisition of right-of-67
way or by acquisition through eminent domain. 68
2. In the event that such structure is partially or totally destroyed by natural or 69
accidental causes, the structure may be rebuilt upon approval of a building permit by 70
the Building Official, subject to Subsection 1.5.4D, Damage or Destruction of More than 71
50 Percent of the Gross Floor Area. 72
H. Prior Construction Approved 73
Exhibit A4 –Subchapter 1 Amendments – Option 4
Nothing contained in this section shall require any change in the plans, construction, or 74
designated use of a building legally under construction, or for which a permit for construction 75
has been issued, at the time of passage of this DDC or amendments. 76
I. Applicability of this DDC to Existing Residential Uses and Structures 77
The adoption of this DDC shall not cause any existing, legally established single-family detached 78
dwelling, townhome, or duplex use or structure to become nonconforming. Any single-family 79
detached dwelling, townhome, or duplex structure, lot, and associated site features lawfully 80
existing on the effective date of this DDC shall be deemed a lawful structure, lot, or site feature. 81
1.5.3 Nonconforming Uses 82
A. Limitations on Continuation of Nonconforming Uses of Land 83
1. A nonconforming use may be extended throughout the same building, provided 84
that: 85
a. No structural alteration of the building (or portion of such building 86
containing the nonconforming use in the case of buildings with multiple uses) 87
shall be permitted; 88
b. No additional dwelling units shall be permitted in the building; and 89
c. No additional nonresidential units and/or uses shall be permitted. 90
2. No nonconforming use shall expand into an additional structure. 91
3. Any use of land that was established in the City's extraterritorial jurisdiction and 92
annexed into the City shall be subject to the provisions established in TLGC, Section 93
43.002, as amended. 94
B. Change of Use 95
1. A nonconforming use may be changed to another nonconforming use, provided 96
the Director determines that the new use creates lesser impacts on surrounding 97
properties and is no more intensive than the use it replaces, and no structural 98
alterations to the building are required to accommodate such change, except those 99
alterations necessary to meet accessibility provisions required by state and federal law. 100
2. A nonconforming use that has been changed to a less nonconforming use 101
pursuant to this subsection may not subsequently be changed back to a more 102
nonconforming use. 103
3. A nonconforming use, if changed to a conforming use, may not subsequently be 104
changed back to any nonconforming use unless otherwise permitted by this DDC. 105
C. Existing Uses Requiring a Specific Use Permit 106
The adoption of this DDC shall not cause any existing, legally established use that requires a 107
specific use permit pursuant to Subsection 2.5.2: Specific Use Permit (SUP), to become 108
Exhibit A4 –Subchapter 1 Amendments – Option 4
nonconforming. Any legally established use existing on the effective date of this DDC that has 109
been damaged or destroyed by fire or other natural or accidental causes in whole or in part may 110
be restored to its original condition and is not required to obtain a specific use permit. 111
1.5.4 Nonconforming Structures 112
A. Expansion of a Nonconforming Structure 113
A nonconforming structure may only be expanded or enlarged pursuant to Subsection 1.5.2C, 114
and any such expansion or enlargement shall be in full compliance with this DDC. 115
B. Increasing Level of Nonconformity Prohibited 116
A nonconforming structure shall not be altered in a way that increases the nonconformity of the 117
structure, but any structure or portion of a structure may be altered to decrease the 118
nonconformity of the structure. 119
C. Damage or Destruction of Less than 50 Percent of the Gross Floor Area 120
A nonconforming structure that has been damaged or destroyed by fire or other natural or 121
accidental causes may be restored to its original condition, provided that: 122
1. The extent of the damage does not require the reconstruction of more than 50 123
percent of the gross floor area of the nonconforming structure. For purposes of this 124
provision, the 50-percent threshold shall apply to each individual structure, and not 125
cumulatively to multiple structures on one lot; and 126
2. A building permit is issued for the work to be performed and such work is 127
commenced within one year of such event and completed within 18 months of such 128
event. By written request from the property owner, the Director may grant one 129
extension of either the work commencement and/or the completion of work time 130
period. 131
3. A restoration or reconstruction of the structure in violation of this subsection 132
immediately terminates the right to operate the nonconforming structure. 133
D. Damage or Destruction of More than 50 Percent of the Gross Floor Area 134
A nonconforming structure that has been damaged or destroyed by fire or other natural or 135
accidental causes shall not be rebuilt or occupied, except in conformance with this DDC. 136
1.5.5 Nonconforming Lots 137
A. A structure situated on a nonconforming lot shall be considered a nonconforming 138
structure, subject to the provisions of this Section 1.5. 139
B. A nonconforming lot that was made nonconforming by virtue of enactment of this DDC 140
may be used for construction of a building allowed in the applicable zoning district, provided 141
that all other zoning district and dimensional standards are met, unless as otherwise provided 142
for in this Section 1.5. 143
Exhibit A4 –Subchapter 1 Amendments – Option 4
C. A structure on a nonconforming lot deemed nonconforming by virtue of Subsection 144
1.5.4C may be restored to its original condition pursuant to Subsection 1.5.4C. 145
1.5.6 Nonconforming Site Features 146
A. For purposes of this provision, the term “nonconforming site feature” includes any 147
driveway, off-street parking or loading area, building coverage, landscaping, buffer, or screening 148
element that lawfully existed per regulations in place prior to the effective date of this DDC, as 149
well as the lack of any such feature required by subsequently enacted City regulations. 150
B. A lawfully nonconforming site feature may continue in its existing condition unless and 151
until full or limited compliance with the development standards of this DDC, as required in 152
Section 7.2: Applicability. 153
C. No action shall be taken that increases the degree of the nonconformity of a site 154
feature. 155
1.5.7 Nonconforming Signs 156
Nonconforming signs shall comply with Municipal Code of Ordinances, Chapter 33.10, Nonconforming 157
Signs. 158
1.5.8 Amortization of Nonconforming Uses or Structures 159
A. Initiation of Proceedings 160
The City Council may initiate proceedings to amortize a nonconforming land use or structure. 161
B. Consideration by Zoning Board of Adjustment 162
1. Generally 163
The Zoning Board of Adjustment may require the termination of nonconforming uses of 164
land or structures under a plan whereby the value of the structure and facilities can be 165
amortized within a definite period of time, taking into consideration the general 166
character of the neighborhood and the necessity for all property to conform to the 167
regulations of this DDC. 168
2. Criteria for Determining Amortization Period 169
Before the Zoning Board of Adjustment may determine an amortization period, it shall 170
consider the following factors: 171
a. The owner's capital investment in the structures on the property at the 172
time the use became nonconforming; 173
b. The amount of the investment realized to date from revenue generated 174
by the property and the amount remaining, if any, to be recovered during the 175
amortization period; 176
c. The existence or nonexistence of lease obligations, as well as any 177
contingency clauses therein permitting termination of such leases; 178
Exhibit A4 –Subchapter 1 Amendments – Option 4
d. Removal costs that are directly attributable to the establishment of a 179
termination date; and 180
e. Other costs and expenses that are directly attributable to the 181
establishment of a termination date. 182
3. Cessation of Use 183
If the Zoning Board of Adjustment establishes a termination date for a nonconforming 184
use or structure, the use shall cease operations on that date and the owner shall not 185
operate it after that date unless it becomes a conforming use or structure. 186
1.5.9 Illegal Nonconformities 187
A nonconformity becomes illegal when: 188
A. A nonconforming structure is destroyed or substantially destroyed by an intentional act 189
of the owner or an agent without a proper permit or other required city approval. If this occurs, 190
the nonconforming structure shall lose its nonconforming status and shall be required to 191
conform to existing codes. If a nonconforming use was also in the structure, the nonconforming 192
use and all site improvements shall lose their nonconforming status and be required to come 193
into compliance with existing codes; and 194
B. A use, structure, or site improvement results in a nonconformity without being lawfully 195
authorized in accordance with the provisions of this DDC. Such use and/or structure shall cease 196
operations until the required city approvals are obtained. 197
1.5.10 Applicability of Gas Well Reverse Setbacks to Existing Protected Uses or Residential Lots 198
A. All Protected Uses and Residential Lots that were deemed non-conforming as result of 199
Ordinance No. 2010-196, which established the 250 foot gas well reverse setback, are hereby 200
conforming. 201
B. Any existing Protected Use or Residential Lot existing within the Gas Well Reverse Setback 202
radius on the effective date of Ordinance DCA19-0009e [February 11, 2020] are a conforming site 203
feature, lot, or structure, provided all applicable requirements of the Fire Code and underlying zoning 204
district regulations are met. 205
For the purposes of this section, “existing” shall include any existing Protected Use structure, site 206
feature, residential lot, or any lot that is part of a project under TLGC Chapter 245 that has a filed an 207
application for a preliminary plat or general development plan that has not expired as of February 11, 208
2020. 209
Improvements that meet underlying zoning district regulations may be permitted for Protected Uses 210
within the lot boundaries that exist on February 11, 2020; however, if the property is replatted or 211
otherwise subdivided after February 11, 2020, then the new lots must comply with Reverse Setback 212
regulations in effect at the time of plat application. 213
214
Exhibit B –Subchapter 6 Amendments
Subchapter 6: Gas Wells 1
6.1 Integrated Provisions 2
6.1.1 Sections 6.2: Gas Well Development, and 6.3: Gas Well Drilling and Production, relating 3
to gas well development are intended as a set of integrated regulations. Each section may 4
incorporate by reference other applicable provisions of this DDC that pertain to gas well 5
development. 6
6.1.2 Section 6.3: Gas Well Drilling and Production, contains definitions that apply to all 7
provisions regulating gas well development, and identifies impact mitigation standards and 8
other general standards that apply to gas well development. 9
6.1.3 In addition to this Subchapter, Subchapter 5: Use Regulations, establishes zoning 10
classifications for gas well development and Section 2.6.6, Gas Well Development Plat, 11
establishes platting requirements and procedures for gas well development. 12
6.2 Gas Well Development 13
6.2.1 Purpose, Authority and Applicability 14
A. Purpose 15
The drilling and production of gas and the development of gas well facilities within the 16
corporate limits of the City necessitate promulgation of reasonable regulations to prevent 17
devaluation of property; to protect watersheds; to ensure that Gas Well Drilling and Production 18
Activities are compatible with adjacent land uses throughout the duration of such activities; and 19
to assure that such activities conform to The Denton Plan. The regulations contained in Section 20
6.2: Gas Well Development; Subchapter 8: Subdivisions; and Section 6.3: Gas Well Dri lling and 21
Production, are designed to protect the health, safety, and general welfare of the public and to 22
assure that the orderly and practical development of mineral resources is compatible with the 23
quiet enjoyment of affected surface estates. The regulations contained in Section 6.2: Gas Well 24
Development; Subchapter 8: Subdivisions; and Section 6.3: Gas Well Drilling and Production, are 25
designed to implement the purposes set forth in this subsection and are supported by the 26
following findings of fact: 27
1. Gas Well Drilling and Production Activities create externalities that potentially 28
threaten the health, safety and general welfare of persons residing or working on 29
property in proximity to such operations. 30
2. Gas Well Drilling and Production Activities, in the absence of local regulatory 31
controls, may emit high noise levels, produce large volumes of dust, congest local 32
streets, present fire hazards and produce other deleterious effects, all of which fall 33
disproportionately on adjacent land uses, and which can result individually or 34
cumulatively in injury to persons, destabilization of property values, and inhibit the 35
quiet peace and enjoyment of surface uses of real property in the vicinity of such 36
operations. 37
Exhibit B –Subchapter 6 Amendments
3. The City of Denton recognizes that the United States and the State of Texas 38
primarily regulate Gas Well Drilling and Production Activities. Moreover, with the 39
enactment of House Bill 40 on May 18, 2015 (Texas Natural Resources Code, Sec. 40
81.0523), the State of Texas has exclusive jurisdiction over Gas Well Drilling and 41
Production Activities. Municipalities are preempted from regulating said activities 42
except as allowed in Sec. 81.0523(c), which expressly provides that a municipality has 43
authority to regulate certain aspects of aboveground activity related to oil and gas 44
operations. The regulations in this Subchapter are intended to regulate under such 45
authority, in order to implement compatible local objectives that assure the health, 46
safety and general welfare of the City's residents and businesses. 47
4. The proliferation of gas wells and Drilling and Production Sites within the City of 48
Denton creates conflicts between such developments and other existing and future 49
surface uses of the property. In order to assure the compatibility of residential, 50
commercial and industrial uses with gas well development, it is necessary for the City to 51
separate Gas Well Development from other surface uses within the City. 52
B. Authority 53
This Subchapter 6: Gas Wells, is adopted pursuant to authority vested under the constitution 54
and laws of the United States, the State of Texas and the City of Denton. Each authorization 55
identified in this Subchapter 6: Gas Wells, shall be construed as an exercise of the City's zoning 56
powers, pursuant to the Denton City Charter, TLGC Chapters 211 and 212 and the provisions of 57
Subchapter 3: Zoning Districts of this DDC, as well as an exercise of its authority granted by 58
Section 81.0523(c) of the Texas Natural Resources Code. 59
C. Applicability 60
The provisions of Section 6.2: Gas Well Development and Section 6.3: Gas Well Drilling and 61
Production, apply only within the corporate limits of the City of Denton, except as otherwise 62
expressly stated therein. 63
6.2.2 Required Authorization for Gas Well Development in City Limits 64
A. Zoning District Classifications for Gas Well Development 65
1. Gas well development is classified as an industrial land use in all zoning districts. 66
2. Gas well development is permitted as set forth in Table 5.2 A: Table of Allowed 67
Uses of the DDC, subject to the use-specific standards in Section 5.3: Use-Specific 68
Standards, of the DDC and the standards in Section 6.3: Gas Well Drilling and 69
Production. Gas well development also is permitted if authorized by a Master Planned 70
Community ("MPC") or Planned Development ("PD") District. 71
3. In order to foster compatible land use within zoning districts, Gas Well 72
Development within the corporate limits of the City will be subject to reasonable 73
setbacks from Protected Uses and Residential Subdivisions, which vary according to the 74
types of uses authorized in each district. Because many gas wells are already in close 75
Exhibit B –Subchapter 6 Amendments
proximity to existing Protected Uses or Residential Subdivisions, setbacks standards 76

expiration for a Gas Well Development Site Plan or Gas Well Permit based upon whether there 748
are circumstances reasonably beyond the control of the Operator, including any delay on the 749
part of the City in issuing subsequent permits, that justify an extension of the Site Plan or 750
Permits, in order that the Operator may enjoy the same rights in the use of the property that are 751
presently enjoyed by other similarly situated properties, but which rights are denied to the 752
property for which the Site Plan or Permits have expired or are suspended. 753
4. Any action under this subsection B shall require a three-fourths majority vote of the 754
entire Board of Adjustment. 755
5. Any Operator or other person aggrieved by any decision of the Board of Adjustment 756
may present to a court of record a petition, duly verified, stating that such decision is illegal, in 757
whole or in part, and specifying the grounds of the alleged illegality. Such petition shall be 758
presented within 10 days after the date on which the decision of the Board of Adjustment was 759
rendered and not thereafter, and judicial review of the petition shall be pursuant to TLGC, § 760

fumes, dust and vibration. All drilling and production operations shall be conducted in such a 1284
manner as to minimize, so far as practicable, dust, vibration or noxious odors, and shall be in 1285
accordance with the best accepted practices incident to drilling for the production of gas and 1286
other hydrocarbon substances in urban areas. All equipment used shall be constructed and 1287
operated so that vibrations, dust, odor or other harmful or annoying substances or effects are 1288
minimized by the operations carried on at any drilling or production site or from anything 1289
incident thereto to avoid injury to or annoyance of persons living in the vicinity. The site or 1290
structures shall not be permitted to become dilapidated, unsightly or unsafe. Proven 1291
technological improvements in industry standards of drilling and production in this area shall be 1292
adopted as they become available if capable of reducing factors of dust, vibration and odor. 1293
2. Sound Mitigation 1294
Exhibit B –Subchapter 6 Amendments
a. A noise management plan, prepared by a professional qualified in the area of 1295
noise mitigation, and approved by the Gas Well Administrator, detailing how the 1296
equipment used in the drilling, completion, transportation or production of a well 1297
complies with the maximum permissible noise levels of this section will be submitted 1298
with the Gas Well Site Plan Application. The noise management plan must: 1299
i. Identify operation noise impacts; 1300
ii. Provide documentation establishing the ambient noise level prior to 1301
construction of any wellhead, compressor or compression facility; and 1302
iii. Detail how the impacts will be mitigated. In determining noise 1303
mitigation, specific site characteristics shall be considered, including but not 1304
limited to the following: 1305

Section 551.002 and Chapter 211 and are intended to minimize adverse impacts on areas within the 1875
Flood Fringe or ESA, reduce flood damage, and lessen the potential for contaminating surface water or 1876
any water supply. 1877
1. Location of Sites 1878
Drilling and Production Sites shall be located outside floodplains and other ESAs whenever 1879
practicable to minimize adverse impacts on these areas, reduce flood damage, and lessen the 1880
potential for contaminating surface water or any water supply. 1881
2. Riparian Buffers 1882
For all ESAs constituting or containing riparian buffers prior to the approval of a Gas Well 1883
Development Site Plan: 1884
a. If a riparian buffer is designated as "fair" to "excellent" ESA, the designated 1885
protective stream buffer width as specified in Section 7.4, Environmentally Sensitive 1886
Areas of this DDC shall apply, and no encroachments shall be allowed. 1887
b. Within all areas except unstudied floodplains, if the stream is designated as a 1888
"poor" ESA, the designated width of the protective stream buffer 'shall be decreased by 1889
either 50 percent or to the limits of the floodway whichever is greater, but in no 1890
Exhibit B –Subchapter 6 Amendments
instance shall the protective stream buffer width be decreased below 25 feet measured 1891
each direction from the centerline of the existing channel. 1892
3. Tree Mitigation 1893

this Subchapter 6: Gas Wells, shall control. Tree mitigation for gas wells located in an ESA shall 1895
be required and shall be calculated on a one to one replacement value for 100 percent of the 1896
diameter breast height ("dbh") of trees removed from the Drilling and Production Site. Tree 1897
mitigation shall be accomplished by planting replacement trees, within a floodplain, on-site or 1898
off-site with similar tree species or by payment into a Tree Mitigation Fund. Tree Mitigation 1899
Funds that are specific to ESAs will be kept separate from other Tree Mitigation Funds and will 1900
only be used to either acquire wooded floodplain or riparian property that remains in a 1901
naturalistic state in perpetuity, or to purchase conservation easements within riparian or 1902
floodplain areas. Funds may be used to purchase, plant, and maintain trees on public property, 1903
as long as the public property is within a riparian area or floodplain. 1904
4. Tree Removal 1905
Any request to remove tree(s) shall be accompanied by a letter from a certified geologist or 1906
engineer that indicates why the well site cannot be located to avoid the trees. If Operator has 1907
chosen to pay into the Tree Mitigation Fund, such fund s shall be paid prior to approval of a Final 1908
Gas Well Development Site Plan or Gas Well Development Plat for the ESA. 1909
5. Limitation on Well Heads 1910
Only one well head may be placed in the Flood Fringe or other ESA under the following 1911
conditions: 1912
a. Storage tanks or separation facilities shall be constructed at least 18 inches 1913
above the established Base Flood elevation plus the surcharge depth for encroachment 1914
to the limits of the floodway having a one percent chance of being equaled or exceeded 1915
in any year. 1916
b. A hydrologic and hydraulic engineering study shall be performed by a Registered 1917
Professional Engineer. The study shall be submitted to the Engineering Department in a 1918
technical report for review by the City Engineer or his designated representative. The 1919
report shall demonstrate that the proposed facilities will have no adverse impacts on 1920
the carrying capacity of the adjacent waterway nor cause any increases to the elevations 1921
established for the floodplain. When the Special Flood Hazard Areas (SFHA) on the 1922
subject site is designated as "Zone A" on the FIRM Panel, or the SFHA is not identified on 1923
the FIRM Panel, the following approximate method may be used to evaluate the impacts 1924
from gas well development. A flow rate shall be calculated using procedures set forth in 1925
the City of Denton Drainage Criteria Manual. Using Manning's Equation with an estimate 1926
of the average slope of the stream, measurements of a single irregular cross-section 1927
geometry at the well site, and the one hundred-year discharge rate, the average velocity 1928
and normal depth may be calculated. Calculations shall be provided for the unaltered 1929
Exhibit B –Subchapter 6 Amendments
existing channel cross-section and for the proposed modified channel cross-section and 1930
submitted to the City for review and approval prior to construction within these areas. 1931
c. No more than 10 percent of the flood fringe, within the limits of the Gas Well 1932
Development Site Plan or Gas Well Development Plat, may be filled. 1933

District for the land subject to the Watershed Protection Permit, as well as the standards in 1936
Subsection 6.3.9D and any other applicable requirements contained in this Section 6.3: Gas Well 1937
Drilling and Production and Section 6.2: Gas Well Development, shall apply. 1938
E. Post-Approval Procedures 1939
1. If evidence from water quality monitoring efforts indicates that contamination is 1940
occurring from gas wells, the Operator shall remove, cause to be removed, or otherwise 1941
remediate contamination, as required by the Gas Well Administrator including but not limited to 1942
Waste Minimization Practices established by the RRC. Cleanup operations shall begin 1943
immediately. A re-inspection fee shall be charged as established by the City Council and 1944
published in the Application Criteria Manual. 1945
2. An associated Watershed Protection Permit shall expire with the expiration of the Gas 1946
Well Development Site Plan or Gas Well Development Plat and may not be extended prior to 1947

3. All other standards in the DDC shall apply to cluster subdivisions unless modified by the 15
cluster subdivision standards in this Subsection 8.3.4. 16
4. In the case of conflict between the provisions of Table 8.A: Cluster Subdivisions, and any 17
other portion of this DDC, the provisions of this Table 8.A: Cluster Subdivisions, shall govern. 18
19
C. Review and Approval of Cluster Subdivisions 20
1. Cluster subdivisions require approval of a planned development (PD) and shall be 21
reviewed through the rezone to a planned development (PD) district procedure in Subsection 22
2.7.3: Rezone to a Planned Development (PD) District. 23
a. A PD is not required for cluster subdivision standards to be applied to sites affected by 24
Gas Well Reverse Setbacks as provided for in Subsection 6.2.6C.2. 25
2. Cluster subdivisions shall be reviewed through the preliminary plat and final plat 26
procedures in Section 2.6, Subdivision Procedures. 27
D. Cluster Subdivision Minimum Standards 28
The minimum standards for cluster subdivision lots are established in Table 8.A: Cluster Subdivisions 29
below. The measurements and exceptions in Section 3.7, shall also apply to cluster subdivision lots 30
