MEMORANDUM  
 
TO: 
 
Jose Macias, Planner/GIS 
FROM: 
Bryce Christo, P.E., Assistant City Engineer 
SUBJECT: 
Nexen DC Development Application Review  
DATE: 
09-26-22 
 
Below are the Engineering Department’s comments for the above referenced submittal provided 
in September 2022. These items will have to be addressed prior to the Planning and Zoning 
Meeting. 
 
Narrative (These items were not addressed with the Development Application submittal) 
1. Project Proposal – It is noted that the project will be built in two phases. All offsite 
improvements will be required in Phase 1. A Phasing Plan per Section F of the City’s 
Design and Development Standards Manual (DDSM) shall be provided with the 
Development Application. 
2. Site Design – The Narrative states that the project is requesting a parking variance due to 
the proposed building being a warehouse and that the number of spaces required per City 
Code is much greater than is required. A Parking Waiver must be submitted and shall 
include the number of spaces required per City Code, the number of spaces actually 
required by the site and how that number was determined and explain how additional 
spaces can be accommodated, if required, in the future. The Waiver shall include a 
breakdown per lot/building. 
3. How many employees are anticipated to be on site during a typical shift per building? 
How many shifts will there be?  
 
The below items will have to be addressed during the Construction Plan Submittal. 
 
Site Plan/Civil Plans 
4. Add the following to the plans: 
a. The right of way width of both Ramirez Road and Dysart Road. 
b. Exterior signs 
5. Property Data Section 
a. The APN for the site is 509-18-978. 
b. Show a breakdown for each building showing the areas of the warehouse and the 
office. 
c. Show the number of parking spaces provided per lot/building. 
6. It appears Building A has 188 parking spaces, Building B has 188 parking spaces and 
Building C has a 199 parking spaces.  If this is accurate, each lot/building will require 5 
standard ADA spaces and one van accessible ADA space. The Site Plan appears to meet 
these requirements but please verify.

2 
 
7. The City will construct the five lane (2-M-2) roadway section for the ultimate Dysart 
Road and both the right of way and 8-foot PUE along the Nexen property have already 
been dedicated. The project is responsible for an eight-foot-wide detached meandering 
sidewalk, streetlights, ITS conduit and landscaping/irrigation along the Dysart Road 
frontage. The project will also be responsible for any deceleration/turn lanes and 
associated right of way/easement revisions.  
8. The project is responsible for a six-foot-wide sidewalk (meandering if possible) and 
landscaping/irrigation along Ramirez Road. The project will also be responsible for any 
deceleration/turn lanes and associated right of way/easement revisions. 
9. The project is responsible for the cost of 25% of the future traffic signal at Ramirez Road 
and Dysart Road which is $179,690.50 as calculated by the City’s Engineering consultant 
(see attached cost estimate). 
a. The property owner shall pay the above fee to the City at the time of, and as a 
condition to, the issuance of the certificate of occupancy for the first building. 
b. This payment will constitute the property owner’s sole obligation with respect to 
the traffic signal. 
c. The payment will be refunded if the City abandons the traffic signal or the 
construction of the signal has not commenced within 10 years of the payment to 
the City. 
10. A 1 foot Vehicular Non-Access Easement (VNAE) is required along Dysart Road except 
at the proposed driveways. 
11. It appears the three lots will share utilities, access, retention, etc. An Agreement will need 
to be in place that establishes this. 
12. The northernmost proposed driveway on Dysart Road shall be right in/right out only. Of 
the other two driveways on Dysart Road, one must be right in/right out and one may be 
full access.  It is recommended to coordinate the final location with the developer on the 
east side of Dysart (Dermody Properties) and/or come to an Agreement with the property 
owner to the south to have the southernmost drive aisle straddle the property line. 
13. A Design Exception will be required for the following: 
a. Providing a full access driveway on Ramirez Road within 660 feet of the 
Dysart/Ramirez intersection, measured from nearest face of curb to nearest face of 
curb. This will have to be addressed in the TIA. 
b. Having a driveway spacing of less than 150 feet on a collector road, measured 
from nearest face of curb to nearest face of curb. The west driveway on Ramirez 
Road is approximately 120 feet away from the approved Cavco driveway to the 
west. This will have to be addressed in the TIA. 
14. The driveways shall be per MAG or City details. The Site Plan calls out City type 
driveways but the design shown on the Site Plan does not match the City Details of 251-1 
or 251-2. 
15. If any portion of the driveway ramp/walkway is proposed within the Nexen property, a 
Pedestrian Access Easement shall be dedicated to the City.  
16. Stop signs are recommended at each driveway. Verify all driveways have a minimum 
throat of 50 feet unless they could potentially be signalized in the future in which the 
length shall be a minimum of 150 feet. 
17. If a driveway is either designated for truck entry or prohibits use by trucks, please 
provide the necessary signage. Verify that any driveway to be used by a truck can 
accommodate a WB-67 vehicle without encroaching into the adjacent lane. 
18. Verify that the sight distance requirements at each proposed driveway are per City Detail 
EM-158. The linework shown on the Site Plan appears inaccurate.

3 
 
19. Show the separation between the proposed site driveways and the proposed adjacent 
driveways. 
20. Keep the sidewalk along Ramirez Road within the right of way. This sidewalk can be 
attached if necessary. The sidewalk along Dysart Road shall be detached and meandering 
if possible. 
21. 6-inch MAG type curbing is required around all driveways and parking lots. Curb that 
carries drainage shall include a gutter. The curbing shall be no closer than 3 feet to any 
property line.  
22. The trash enclosures shall be per City Detail EM-113. 
23. Pre-Application Note 5 may no longer apply as it is believed that the farmer has ceased 
farming the subject property. Please contact Dermody Properties for confirmation.   
24. Plans shall include applicable City Notes. Call out MAG, City, etc. details to be used. 
Use the City’s Design & Development Standards Manual (DDSM) as a guide for the final 
design. 
 
Preliminary Grading & Drainage Plans 
25. Verify the slope does not exceed 2% in any direction within ADA parking spaces. 
26. Side slopes adjacent to the public right of way, areas where pedestrian access is permitted 
and within Public Utility Easements (PUE) shall be 6:1 or flatter. There shall be at least 
two feet of level ground between any wall or vertical obstruction and the top of any side 
slope grading.  
27. Heights and/or elevations for any proposed retaining walls will be required. Structural 
drawings for the proposed retaining walls shall be reviewed by the Building Safety 
Division.  Safety rail is required when the vertical drop is 30 inches or more and 
recommended when 12 inches or more. 
28. Show the basin overflow elevations and the ultimate outfall of the site. 
29. The finished floor elevations of the proposed buildings shall be a minimum of 12 inches 
above the 100-year base flood elevations and high-water level of any adjacent retention 
basin and 14 inches above the ultimate outfall of the site.  
30. The proposed retention basins or underground pipes shall be located a minimum of 4 feet 
away from any structures and shall not be located within any building setbacks, 
easements, or fire lanes.  
31. Trash racks and safety rails are recommended for any on-site headwalls. 
32. The retention pipe for Basin B1 is missing drywells. 
33. The Dysart Road plans show a proposed scupper 585 feet south of the Ramirez Road 
southern curb line. A second scupper will be required near the southern boundary of the 
site. Dysart Road AutoCAD files can be provided upon request. There is also an existing 
catch basin on Ramirez Road that outlets to the project site. 
 
Preliminary Utility Plans 
34. The Utility Plans shall show all utilities and utility easements including electric, gas, 
phone and cable. 
35. All proposed water and sanitary sewer lines will be private so the easement can be 
removed.  The onsite improvements shall be designed per City standards and the offsite 
improvements shall be designed per EPCOR standards.   
36. The fire line requires a backflow preventer at both entrances into the site. 
37. The domestic water and landscape service lines shall tie in to the mains in Dysart Road 
and/or Ramirez Road and shall have their own meter and backflow preventer.

INTRODUCTION 
 
The purpose of this document is to provide criteria for the preparation of Traffic 
Impact Studies for new land developments or additions to existing developments 
and to establish the report format for these studies. 
 
STUDY REQUIREMENTS 
  
A Traffic Impact Study prepared by a Registered Professional Engineer in the 
State of Arizona is required for all developments unless waived in writing by the 
City Engineer. If the Traffic Impact Study is waived, a Traffic Impact Statement is 
required that includes the total vehicle trips that will be generated by the 
development, using the Institute of Transportation Engineers (ITE) Trip 
Generation publication (most recent edition). 
 
STUDY CLASSIFICATIONS 
  
Traffic Impact Studies will be classified into three categories: 
 
Category I- 
Those developments that are estimated to generate 500 
vehicle trips or less during either of the a.m. or p.m. peak 
hours. 
 
Category II- 
Those developments that are estimated to generate more 
than 500 vehicle trips during either of the a.m. or p.m. peak 
hours but not more than 1,000 peak hour trips. 
 
Category III- 
Those developments that are estimated to generate more 
than 1,000 vehicle trips during either of the a.m. or p.m. peak 
hours. 
 
The developer should first estimate the number of vehicle trips that will be  
generated by the proposed development and provide this information along with 
the other suggested study elements of the Traffic Impact Study to the City for 
Review and approval prior to the start of construction.

4
 
 
TRAFFIC STUDY ANALYSIS AND APPROACH 
 
 The following presents the specific items to be included in a Traffic Impact 
Study. 
 
Study Area 
 
a) All site driveways  
 
 
 
 
 
All categories 
 
b) All major intersections within 1 mile of the study site, 
    either signalized or un-signalized. 
 
 
 
All categories 
 
c) All driveways where traffic movements could be  
    affected by new driveway traffic movements.  
 
All categories 
 
d) Additional locations as requested by the reviewing 
    agency. 
 
 
 
 
 
 
 
All categories 
 
Study Time Frame 
 
The study should include, as a minimum, an analysis of the expected traffic 
conditions for the time period when the development is expected to open. The 
opening day conditions should include all of the proposed development traffic as 
if the development was fully completed and occupied. 
 
Additional study years should be included as follows: 
 
Category I: 
Opening year and 5 years in the future. 
 
Category II: Opening year, 5 years and 10 years in the future. 
 
Category III: Opening year, 5 years, 10 years and 20 years in the future. 
 
The study for phased construction developments should include an analysis for 
each year that planned new phased construction is to be started. In addition, the 
required 5, 10 or 20 year analysis after the start of the last phase of the 
development as stated above for the specific categories. 
 
Analysis Time Periods 
 
The study should include an analysis of the impact of the development traffic for 
the typical adjacent street peak hour conditions which normally occur within the 
time periods from 6:00 to 9:00a.m. and 3:30 to 6:30p.m. on a typical weekday 
and an analysis of the impact of the development daily weekday traffic generated 
on the adjacent street system and site driveways. In addition, if requested by the

5
 
City, additional time periods and or weekend analysis may be required in the 
study if the developer has unusual peaking characteristics or if the adjacent non-
site traffic conditions warrant an analysis of other peak traffic time periods. 
 
Data Collection 
  
 
The traffic impact study should include information on the following existing and 
proposed conditions within the study area: 
 
a) Traffic Volumes 
 
1. Existing and proposed traffic volumes for the adjacent existing and 
proposed intersections and driveways to include daily weekday 
a.m. peak hour and p.m. peak hour (and other time periods as 
noted in the previous section). Daily traffic volumes should be 
provided as a 24-hour directional roadway section count and peak 
hour volumes should be provided by specific intersection or 
driveway turning movement directions. 
 
2. Existing traffic volume data should be adjusted to average 
conditions based on City adjustment factors or appropriate 
adjustment factors available from other public agencies. 
 
3. Projected traffic volumes should be based on available traffic 
projections from the Maricopa Association of Governments (MAG), 
other appropriate documented traffic projected sources or historical 
traffic volume trends. Projected traffic volumes shall include 
adjustments, as necessary, to reflect other adjacent future 
development. 
 
b) Land Use 
 
1. Existing and proposed land use in the study area should be 
discussed and included in the study as it impacts the proposed 
development street system or driveways. 
 
c) Roadway Conditions  
 
1. Existing and proposed roadway conditions shall be identified 
including pavement type, width, traffic lanes, medians, curb and 
gutter, speed limits, horizontal and vertical curvature and traffic 
control devices.

6
 
d) Crash Experience 
 
1. Crash experience should be documented for the past 36-month 
time period for the adjacent roadway system included within the 
study area. 
 
Trip Generation 
 
The trip generation for the proposed development shall be estimated using the 
latest edition of Trip Generation published by ITE. Exceptions to the use of this 
document must be approved by the City and may include actual traffic generation 
counts from a similar existing facility having the same size and surrounding area 
characteristics or from other recognized sources that provide trip generation data 
not included in the ITE manual. 
 
If proposed within the Traffic Impact Study, adjustments to the site traffic 
generation should be documented to reflect site traffic interaction, pass-by traffic, 
use of other modes of transportation, carpooling or other means of trip reduction. 
Trip reduction methods should be discussed with the City prior to use within the 
report. 
 
Trip Distribution and Assignment 
 
Site traffic shall be assigned to the proposed site driveways and street 
intersections included within the study area based on an analysis of the market 
area for the proposed development. The market area will vary based on the type 
and location of the development. However, as a minimum, the following 
guidelines should be used: 
 
● Residential trip distribution should be based on the locations of employment   
   and commercial attractions and the available street system. 
 
● Commercial, industrial and office trip distribution should be based on the   
    surrounding population densities and the available street system. 
 
The area to be constructed in the development of the site trip distribution should 
normally be within a 10-mile radius of the study site. However, other conditions of 
the proposed development, the adjacent street system and the location of site 
traffic attractors and generators may indicate the need to expand or reduce the 
area of influence. 
 
Traffic Analysis 
 
The study should include the following minimum items for analysis.

7
 
a) Traffic flow conditions, including the level of service using the latest edition 
of the Highway Capacity Manual (Special Report 209, Transportation 
Research Board) 
 
1. An analysis of the existing traffic conditions. 
 
2. An analysis of the future non-site traffic conditions. 
 
3. An analysis of the traffic conditions with the addition of site traffic. 
 
 
b) Roadway capacity conditions using generally accepted daily volume traffic 
demand compared to roadway cross sections. 
 
1. Existing traffic conditions  
 
2. Future non-site traffic conditions. 
 
3. Future traffic conditions with the addition of site traffic. 
 
c) Intersection and driveway traffic control device requirements using results 
of the items below and the Federal Highway Administrations (FHWA) 
Manual on Uniform Traffic Control Devices for Streets and Highways

exclusively for on-site private fire hydrants and/or for interior fire sprinkler systems for buildings.  
Fire Lines shall be utilized for fire protection services only and shall serve only a single property.  
Though EPCOR reviews the engineering plans of the Fire Lines, EPCOR’s approval of the Fire Lines 
is limited only to that portion to be constructed within rights-of-way or water easements. 
 
 
Date of Application:  
 
 
 
 
 
Name of Business that will be served by the Fire Lines:

The Applicant, upon the terms and conditions set forth herein, applies to EPCOR Water Arizona Inc. 
 
(“Utility”) for a fire line connection to be located at  
 
 
 
 
 
 
   
 
 
 
 
 
 
 
 
 
 
 more fully described in Exhibit A. 
 
 
Applicant agrees to be bound by all the terms and conditions of this Application and of the Utility’s rules and 
regulations for water service as on file with and approved by the Arizona Corporation Commission as they 
presently exist or as they may hereafter be modified, altered, or changed from time to time.  In case of any 
conflict with the provisions of this Application, the rules and regulations for water service shall control. 
 
Subject to the previous paragraph, terms and conditions that are binding upon acceptance of this 
Application by the Utility are as follows: 
 
1. The Applicant is responsible for all Work, which is defined as the connections to the distribution 
main, the installation of the fire lines, the installation of the control valves and backflow prevention 
assemblies, and all required excavations, saw-cutting, backfilling, pavement and sidewalk 
replacements, permits, approvals, and associated work, all to the satisfaction of Utility, the local fire 
department, and the entity that owns the rights-of-way.  This Work shall be in compliance with the 
details in Exhibit B and with the design requirements listed in Exhibit C, and with all requirements 
of the local fire department and the entity that owns the rights-of-way.    
 
2. All Work described in Paragraph 1 above that occurs within the right-of-way or water easement, 
including the installation of the backflow prevention assembly, shall be subject to inspection, testing 
and acceptance by the Utility before commencement of service.  Applicant will comply with Utility’s 
1

inspection and testing requirements for the Work.  Applicant will provide Utility two business 
days’ prior notice before the Work begins, and when any portion of the Work is ready for 
inspection and testing.  Utility will then promptly inspect and test the Work to determine if such has 
been constructed in accordance with Utility’s specifications and details.  As a result of Utility’s 
inspection and testing, Utility may provide written notification to Applicant of punch list items that 
require correction and Applicant agrees to promptly correct all defects and deficiencies in 
construction, materials and workmanship. 
 
3. Upon Applicant’s receipt of invoice from Utility, Applicant will pay to Utility a non-refundable 
inspection and administration fee equal to $2,500.00.  The inspection and administration fee is 
to compensate Utility for the cost of its administration, coordination, engineering reviews, 
inspections, testing and approval incurred by Utility in connection with the design, construction, 
installation and connection of the Fire Line(s).  This fee is a non-refundable contribution in aid of 
construction.  Applicant will not begin any work until Utility receives payment of the inspection and 
administration fee.   
 
4. The Applicant shall utilize the services of an Arizona licensed and insured contractor to perform the 
Work.  At a minimum of seven (7) calendar days prior to the start of Work, the Applicant will 
submit the following documents to Utility for its review and approval: 
 
a. a copy of the contractor’s license;  
b. a copy of the contractor’s certificate of insurance (EPCOR Water Arizona Inc. must be listed 
as an Additional Insured); 
c. a copy of the contractor’s bid. 
 
Utility will verify and confirm whether the contractor has the appropriate license classification to 
perform this type of Work, and will verify that the contractor’s insurance is current and effective.  
Applicant will not begin any Work until written approval of these items is obtained from the 
Utility.  Written approval may be in the form of an e-mail. 
 
5. Applicant will pay all of the costs of permitting, constructing, installing, and connecting the Fire 
Line(s) including, but not limited to, the costs of engineering, materials, labor, transportation, 
equipment, necessary permits and approvals, easements, testing, corrections, insurance and 
bonds, wherever applicable.  Applicant’s costs for the Fire Line(s) shall be considered a non-
refundable contribution in aid of construction. 
 
6. Applicant estimates a construction start date of __________________________________, 20___.  
Applicant will not commence construction until (a) Applicant has given proper notification to Utility’s 
inspector per Paragraph 2, (b) Utility receives payment of the inspection and administration fee per 
Paragraph 3, and (c) Applicant receives written notice of approval per Paragraph 4. 
 
7. The construction and installation of the Fire Line(s) shall be in accordance with good utility and 
engineering practices, the rules, regulations and requirements of the local fire department, Utility’s 
specifications and details, and the requirements of all other agencies having jurisdiction over the 
Fire Line(s) and rights-of-way. 
 
8. If Applicant begins construction of any Work before all of the conditions set forth in Paragraph 6 are 
satisfied, such construction will be at Applicant’s sole risk and subject to repair, alteration or 
reconstruction at Applicant’s expense as directed by Utility or any regulatory agency. 
 
9. After construction of the Work is completed, Applicant will promptly provide to Utility all of the 
following: 
 
a. Copies of all paid bills, invoices and other statements of expenses incurred by Applicant as 
a result of the Work; and, 
2

b.
Lien waivers and releases from contractors, subcontractors and vendors for materials,
equipment, supplies and construction included in the Work.
10. The Fire Line(s) will not be used to provide public utility service until inspected, tested and approved 
by Utility and Final Acceptance of the Work has occurred.  Utility specifically reserves the right to 
withhold Final Acceptance of the Work unless the Work has been constructed in accordance with the 
terms of this Application and are reasonably satisfactory to Utility upon inspection and testing.
11. Utility will notify Applicant of Utility’s Final Acceptance of the Work within ten (10) days after the 
satisfaction of all of the following conditions:
a.
Applicant has corrected all punch list items identified by Utility;
b.
Applicant has paid all fees required by this Application and by the terms of Utility’s then-
current and applicable tariffs;
c.
Applicant has delivered to Utility all documents required in Paragraph 9: and,
d.
If Utility has determined that an easement is required, Applicant has, at no cost to Utility, 
granted or caused to be granted to Utility, perpetual rights-of-way and easements and 
obtained all necessary zoning and other governmental approvals as required, each in a form 
and with substance reasonably satisfactory to Utility’s legal counsel, for Utility’s ownership, 
operation, maintenance and replacement of that portion of the Fire Lines(s) within the 
easement, including adequate access from public roadways.  As a condition to Applicant’s 
conveyance of easement rights to Utility, Utility may require Applicant to deliver to Utility, 
among other documents and information reasonably requested by Utility, an ALTA survey 
and a title report pertaining to the real property subject to such easement, both of which must 
be in form and substance satisfactory to Utility’s legal counsel. Unless otherwise mutually 
agreed upon in writing, such easements:
i.
will be free of physical encroachments, encumbrances or obstacles that will 
materially impair Utility's maintenance and operation of that portion of the Fire Line(s) 
between Utility’s distribution line and the newly installed backflow preventer;
ii.
will have a minimum width of 20 feet; and,
iii.
will specify that the service lines will be separated by a reasonable distance from 
other utility lines and facilities so as to prevent damage or conflicts in the event of 
repairs or maintenance.
12. Concurrently with Utility’s Final Acceptance of the Work, if an easement was granted for any portion 
of the Fire Line(s), all lines within the easement shall become, and shall thereafter remain, as 
between Utility and Applicant, the sole property of Utility without the requirement of any written 
document of transfer to Utility.  Applicant represents and warrants to Utility that, at the time of such 
transfer, Utility will receive good and marketable title to the conveyed Fire Line(s), free and clear of 
any and all liens, claims, mortgages or other encumbrances.  Applicant shall furnish any document 
pertaining to ownership and title as may be requested by Utility, including documents which evidence 
or confirm transfer of ownership and possession to Utility, and the good, merchantable and lien-free 
title to such portions of the Fire Line(s).  All risk of loss of the Fire Line(s) shall be with Applicant until 
title to that portion of the Fire Line(s) is transferred to Utility in accordance with the terms of this 
Application.
13. WARRANTY – For one year after Utility’s written Final Acceptance of the Work, Applicant will, upon 
Utility’s reasonable request, promptly correct any and all defects and deficiencies in construction, 
materials and workmanship in the Work discovered by Utility.
14. Neither Utility’s inspection nor acceptance of the Work relieves or limits Applicant’s responsibilities 
and liabilities under this Application.
15. Utility does not provide fire protection services and does not warrant, guarantee or represent that any 
water utility services it provides will comply with any fire-protection requirements of any 
3

governmental agency, or of any county, municipal, or private fire protection providers.  Utility will 
allow public and private fire protection providers to use water from its system for fire-fighting 
purposes, provided that Utility’s normal system demands are first met and water system pressure is 
not decreased to less than 20 pounds per square inch. 
 
16. Utility does not guarantee a continuous supply of service or a constant water pressure of service.  
Utility is not liable for damages occasioned by such events, interruptions or failure to commence 
service or unsatisfactory service or any act or failure to act arising out of this Application caused by 
an act of God or the public enemy, accident, fire, explosions, strikes, riots, war, delay in receiving 
shipments of required material, order of any court or judge granted in any bona fide adverse legal 
proceedings or action, or any order of any commission or tribunal having jurisdiction in the 
premises; or without limitation by the preceding enumeration, any other act or thing reasonably 
beyond its control or incident to interruptions necessary for repairs or changes in Utility’s production, 
storage, transmission, distribution, collection, and other related facilities. 
 
17. Applicant will defend, indemnify and hold harmless Utility, its officers, directors, agents, and 
employees from and against any and all claims, damages, judgments, fines, penalties, 
assessments, costs and expenses, including attorneys’ fees and court costs, to which they or any of 
them may be subjected by reason of injury, death, loss, claim, penalty, assessment or damage 
caused or contributed to by the active or passive negligence or willful misconduct of Applicant, its 
agents, servants, employees, contractors or subcontractors in the execution of, or failure to execute, 
Applicant’s obligations under this Application; provided, however, that Applicant shall not be 
required to indemnify Utility to the extent of any negligent or wrongful acts of Utility, its officers, 
directors, agents or employees. 
 
18. UTILITY WILL NOT BE LIABLE TO APPLICANT FOR ANY INCIDENTAL, CONSEQUENTIAL, 
SPECIAL, PUNITIVE, OR OTHER INDIRECT DAMAGES, REGARDLESS OF WHETHER SUCH 
DAMAGES ARISE UNDER BREACH OF CONTRACT, TORT, STRICT LIABILITY, OR OTHER 
THEORY OF LAW. 
 
19. This Application represents the entire understanding between the parties with respect to its subject 
matter, superseding all prior communications, understandings and agreements of or between the 
parties with respect to such subject matter.  There are no oral or collateral agreements between the 
parties with respect to such subject matter. 
 
20. Utility reserves the right to deem this Application null and void if Applicant does not begin 
construction of the Fire Line within six months after the date of this Application.  If Applicant has not 
started such construction within six months after the date of this Application, Applicant may issue a 
written request to Utility for an extension of this Application.  Utility’s response to any such request 
for extension will not be unreasonably delayed, but will be within Utility’s sole discretion.  If Utility 
deems the Application null and void, Utility will provide written notice of cancellation of this 
Application to Applicant.
