Final Plat Infrastructure Permit Process Internet: www.maricopa.gov/planning 10/30/19
A SUBDIVISION, is defined by ARS §32-2101. Any
subdivision within the unincorporated area of Maricopa
County must be approved by the Board of Supervisors
prior to being recorded. An application for a Final Plat
and Infrastructure Permit must be filed with the Planning
and Development Department. Please note that
applications must be complete. Intake may reject
incomplete applications and/or applications that are
submitted after 4:00 p.m. Both a pre-application
meeting discussing the submittal requirements and a
pre-submittal meeting documenting the required
submittal documents are required.
ARS § 1605 PROCESS
After the Preliminary Plat is approved, the owner or
authorized agent may submit the Final Plat and related
Infrastructure Plans to the Planning and Development
Department. The Final Plat must meet the requirements
set forth by the Planning and Zoning Commission, the
Maricopa County Subdivision Regulations, and be in
substantial compliance with the approved Preliminary
Plat. The Final Plat and Infrastructure Permit will be
reviewed by Maricopa County Departments of
Transportation, Environmental Services, Stormwater
Quality, Library, Parks and Recreation, Flood Control
District, Drainage Review, Addressing, Building Plan
Review, Comprehensive Planning, and Current
Planning. The Final Plat may also be routed
electronically to applicable fire department, any town
or city within three miles of the site of the plat, and
other interested parties. These reviewing agencies may
require additional information in order to review the
Final Plat.
As of September 13, 2013, both the Final Plat and
Infrastructure Permit process shall be subject ARS §
1605, a State statute that mandates establishment of
timeframes to either approve or deny a “license” as
defined by the statute. The full statute may be viewed
at:
http://www.azleg.gov/arstitle/
The statute sets up two types of review timeframes:
Administrative and Substantive. The Board of
Supervisors (BOS) through the P-30 Licensing Timeframes
Ordinance has adopted a 90 (working) day
administrative timeframe and a 180 (working) day
substantive timeframe for Final Plats and Infrastructure
Permits (Subdivision). These are separate applications
with separate timeframes. An application related to a
residential use is not subject to the statute.
An application that is part of a design build project
may establish a negotiated timeframe process during
the pre-application meeting.
Administrative Review Period
The statutes allow for multiple reviews during the
administrative review period.
Substantive Review Period
Only one review is allowed for the substantive review
period. The County can amend the substantive review
comments to address legal requirements not identified
on the original substantive review comments.
After receipt of the concurrent submittal of both the
Final Plat and the Infrastructure Permit, the statutory
review process differs. Whereas the Infrastructure
Permit is deemed administratively complete at
acceptance of submittal, after receipt of a Final Plat
application, the administrative review period begins
and Planning will review for administrative
completeness. The applicant will receive a formal
response from their assigned planner and may be
required to submit additional information. Once Final
Plat administrative comments have been given to the
applicant, the timeframe clock will stop and will resume
upon resubmittal of the Final Plat application materials.
Once the application is deemed administratively
complete, the planner will formally notify the applicant
and One Stop Shop (OSS) agencies that the Final Plat
has entered the substantive review period. At this time
the Final Plat substantive review will commence and
the Final Plat substantive timeframe clock stops from
receipt of comments until the applicant makes a formal
resubmittal.
**Note: The Infrastructure Permit is on a separate review
and substantive timeframe clock. A Infrastructure
Permit combined review will be provided to the
applicant separately from the Final Plat review
comments at which point the Infrastructure Permit
Substantive timeframe clock will stop.
At any time during the process, an applicant can
check the status of their applications by viewing the
Online Permit Manager on the Planning and
Developments website:
https://accela.maricopa.gov/citizenaccessmcoss/
The applicant’s assigned planner can also be utilized as
a resource for checking the status of the applications.
If at any time comments are given to the applicant, a
notation will be made as to the administrative or
substantive timeframe frame remaining which will not
resume until a resubmittal is made.
