noise will be apparent throughout the area as aircraft transient to and from the 
Barry M. Goldwater Gunnery Range and other flight areas. 
 
Luke Air Force Base may launch and recover aircraft in either direction off its 
runways oriented to the southwest and northeast. Noise will be more noticeable 
during overcast sky conditions due to noise reflections off the clouds. 
 
Luke Air Force Base’s normal flying hours extend from 7:00 a.m. until 
approximately midnight, Monday through Friday, but some limited flying will occur 
outside these hours and during most weekends. 
 
For further information, please check the Luke Air Force Base website or contact 
the Maricopa County Planning and Development Department.” 
 
Such notification shall be permanently posted on not less than a 3 foot by 5 foot 
sign in front of all leasing and home sales offices and be permanently posted on 
the front door of all leasing offices on not less than 8½ inch by 11 inch sign.

Changes greater than 5% either individually or cumulatively shall be processed as a 
revised application with approval by the Maricopa County Board of Supervisors upon 
recommendation by the Maricopa County Planning and Zoning Commission.

Project Summary: 
 
1. 
The applicant is proposing the deletion of condition “e” from DMP2021004 as well as condition 
“f” from DMP2008006, which both read as follows:  
 
“Prior to the approval of any zone change, the master developer shall enter into a development 
agreement with Maricopa County.  Further, prior to approval of any zone change this development 
agreement shall be sign by both the master developer and the designated Maricopa County 
representative(s) and provided to the Maricopa County Planning and Development Department for 
public record.”   
 
The deletion of the two conditions would allow the applicant, in coordination with county legal 
counsel, to dissolve the existing development agreement (DA) between the property owners and 
the county, which was created as a result of these conditions.  The applicant is seeking 
dissolution of the DA to remove the burden of needing approval from all property owners within 
the DMP area to sign off on any zone change requests.  This has become a larger burden over 
the years as the property within the DMP area has been split and there are now several more 
property owners than when the DMP was initially created.  The applicant also notes that the task 
of gathering all property owners to sign off on each zone change proposal within the DMP area 
has proven rather challenging.  
 
2. 
On April 20, 2021 the board of supervisors approved both Z2021141, a zone change request from 
Rural–43 to IND-2, and DMP2021004, a land use designation change from Small Lot Residential 
to Employment/Industrial Center, over the subject parcels.  The applicant applied for the subject 
modification of stipulations on April 6, 2023.

Adopted Plan: 
 
6. 
Tonopah/Arlington Area Plan (adopted September 6, 2000): The Tonopah/Arlington Area Plan 
designates the site as Rural (0-1 du/ac.) but there is also a portion of the DMP along the I-10 and 
339th Ave designated as Community Retail Center. The area plan defines Rural as areas desirable 
for single family residential development but where urban services are limited. Community Retail 
Center is defined as an area appropriate for community and neighborhood uses such as the sale 
of convenience goods and personal services.  
 
Public Participation Summary: 
 
7. 
The applicant worked with staff to formulate an appropriate citizen participation plan.  The 
applicant posted signs and sent mailers to all property owners within the DMP area.  Staff 
received no public comment or opposition to the case as a result of the public participation or 
otherwise.  However, the applicant did attract several other property owners within the DMP area 
to “sign onto” the proposal.  Their signatures are included in the case attachments.  
 
Outstanding Concerns from Reviewing Agencies:

Staff Analysis: 
 
9. 
The proposed deletion of stipulations “f” from DMP2008006 and “e” from DMP2021004 will allow 
the applicant to continue to work with the county legal team to dissolve the development 
agreement in place between the property owners within the Hidden Waters Ranch DMP and the 
county.  Doing so will allow individual property owners the ability to bring forth new zone change 
requests without signoff of all property owners within the Hidden Waters Ranch DMP area.  Staff 
notes that this request was done in coordination with county legal counsel.  In addition, the 
Hidden Waters Ranch DMP is approaching twenty years old and may be out of date.  The proposal 
is in line with several general plan goals and policies as it will allow new development to come to 
the area and take on a reasonable and proportional share of infrastructure cost resulting from 
each individual development.  Staff has no concerns of the proposal. 
 
 
Recommendation: 
 
10. 
Staff recommends the Commission adopt a motion recommending that the Board of Supervisors 
approve DMP2023002 subject to conditions ‘a’ – ‘o’:

I. Description and Purpose of Proposal 
 
On behalf of 339th & I-10, LLC (“339th”), who is the owner of property generally located 
south of the 1-10, north of Buckeye Road, generally between 339th Avenue on the east and 351st

to delete the stipulations as shown below:  
1) Case #DMP2021004 
e. Prior to the approval of any zone change, the master developer shall enter into a 
development agreement with Maricopa County. Further, prior to approval of any 
zone change this development agreement shall be signed by both the master 
developer and the designated Maricopa County represenatives(s) and provided to 
the Maricopa County Planning and Development Department for public record. 
 
2) Case # DMP2008006 
f. Prior to the approval of any zone change, the master developer shall enter into a 
development agreement with Maricopa County. Further, prior to approval of any

developer and the designated Maricopa County represenatives(s) and provided to 
the Maricopa County Planning and Development Department for public record. 
 
 
339th Requests these modifications and recinding of the existing Development 
Agreement in order to allow 339th and other affected property owners to develop their 
properties. Since the above stipulations were created, property in the Hidden Waters 
Ranch Master Planned Community has been sold to various parties. The approval of 
these requests will facilitate the development of underutilized land in Maricopa County. 
However, this request does not propose any development or phasing. All proposals by 
other owners are not known at this time. 339th LLC will pursue development in 
accordance with their the Major Amendment to the Development Master Plan approved 
in case DMP2021004 and Major Zone Change Amendment Application in case 
Z2021141.  
 
II. Surrounding Properties  
 
 
The Overall Hidden Water Ranch Development Master Plan is an existing 1,314 
acre master planned community. The Surrounding area largely remains vacant with some 
large lot residential uses. The surrounding zoning is largely RU-43 with the exception of

3 
 
the parcels rezoned to IND-2 by 339th. The development of this currently underutilized 
land will be a benefit to the area and the community as a whole.  
  
III. General Plan Conformance 
 
These requests will help to facilitate development of underutilized land and will 
promote valuable uses including the uses proposed by 339th to provide industrial and 
employment type uses that are in demand in this area. This request for modification of 
stipulation and to rescind the existing development agreement will promote the orderly 
development of properties and is supported by goals and policies of the General Plan as 
follows: 
 
Land Use Goal #1: Achieve balanced and efficient development patterns. 
Land Use Goal #4: Exercise sound financial management through land use decisions 
that build the county’s fiscal strength. 
Economic Growth Goal #4: Create and grow a diverse business climate 
Cost of Development Goal #1: Exercise sound financial management and build the 
County’s fiscal strength 
Cost of Development Goal #2: New development pays for its proper and reasonable 
share of the costs of new infrastructure, services, and other public improvements 
 
Response: Modifying this stipulation and recinding the existing development agreement 
will remove a barrier and allow efficient development that will add to the County’s fiscal 
strength be promoting new uses that will pay their share of public improvements. 
 
IV. Infastructure 
 
 
These requests propose no changes for accessibility, circulation, community 
facilities and services, or publuc utilities and services. 339th has already received 
entitlement approvals (which include infastructure anaylsis) as stated above. Any further 
entitlement approvals by 339th or other land owners within the Master Plan Area will 
require approvals where the County will have the opportunity to analyze and impacts on 
infastructure.

This application is to modify stipulations(s) for future development and does not 
include a Plan of Development. 
 
PND Engineering Plan Review (DPR, FCD and PND Transportation) has reviewed the 
1st submittal of the Modification of Stipulations application routed for review on April 
14, 2023, and has no comments. 
 
The following conditions will apply: 
 
1. Without the submittal of a precise plan of development, no development approval 
is inferred by this review, including, but not limited to number of proposed building 
lots/units, drainage design, access and roadway alignments. These items will be 
addressed as development plans progress and are submitted to the County for 
further review and/or entitlement. 
 
2. A traffic impact study must be submitted with future entitlement (POD/Plat) 
application(s) contained within the DMP. 
 
3. Engineering review of planning entitlement cases is conceptual in nature. All 
development and engineering design shall be in conformance with Section 1205 
of the Maricopa County Zoning Ordinance; Drainage Policies and Standards; 
Floodplain Regulations for Maricopa County; MCDOT Roadway Design Manual; 
and current engineering policies, standards and best practices at the time of 
application for construction.

Hi Joseph,  
 
The property subject to the request is located approximately 1 mile west of the western edge of the City of Buckeye’s 
planning area. As such, we don’t formally have any comment on this – but from a best planning practice standpoint, I 
would recommend that if a development agreement that defines street and utility infrastructure improvements is no 
longer a requirement for this Development Master Plan , that some other mechanism is in place to ensure that such 
improvements are master planned and constructed in larger phases, not piecemealed as each individual lot may 
develop.   
 
Thanks,  
Ken Galica
