Request to consider: 
Adopt Ordinance O24-05-03 to abandon the roadway rights-of-way along Butler Drive from Dysart Road to

Goal/Purpose of Request: 
The applicant is requesting the abandonment of the rights-of-way along the new Butler Drive between Dysart 
Road and 127th Avenue Alignment and along 129th Avenue between Butler Drive and the Northern Parkway. 
The applicant, on behalf of the owner of Maricopa County Assessor Parcel Nos. 501-45-986 and 501-45-985

Background 
Maricopa County Department of Transportation (MCDOT) and the cities of Glendale, Peoria and El Mirage 
entered into an Intergovernmental Agreement dated December 26, 2008, to identify and define the 
responsibilities of the County and the cities for cost sharing, design, construction, construction management, 
rights-of-way acquisition, utility relocation, and maintenance of the Northern Parkway Project. As part of the 
Northern Parkway Project, MCDOT designed and constructed Butler Dr between Dysart Rd and 127th Ave 
Alignment and 129th Ave between Butler Dr and the Northern Parkway. 
General Plan, Zoning & Land Use 
The 2020 General Plan Land Use Map identifies the site as being part of the Commerce and Industrial Park 
Planning Area and is compatible with the plan. The site is zoned Employment/Industry (EI) and the proposed 
data center use requires a conditional use permit for approval. 
ARS 28-8481 Land Use Compatibility 
The site is located inside the Luke Air Force Base (LAFB) Noise Contour Zone and is subject to A.R.S 28-
8481, land use compatibility regulations. 
 Ownership of Roadways 
As part of the abandonment process, Maricopa County will relinquish its interests and easements located within 
the subject roadway at a Board of Supervisors’ meeting to be held on May 22, 2024, leaving the City as the sole 
owner of roadways. 
Public Utilities 
The applicant has also requested the abandonment of the current Public Utility Easements (PUEs) within this 
area; however, this Council action request may not include the PUEs abandonments at this time as the utility 
companies currently using the easements will have to agree on the abandonments and to relocate their facilities, 
if any. 
Community Involvement 
Businesses along both sides of Butler Drive, between 125th Avenue and 127th Avenue alignment, were visited 
by the Economic Development Manager on May 9, 2024, to inform them about the roadway abandonment 
request.

Traffic Impact Analysis 
A Traffic Impact Study was completed on April 8, 2024. The report presented the analyses and results of the 
proposed land use of the LogistiCenter at Copperwing development and the impacts of removing the Butler 
Drive extension and 129th Avenue. The proposed development will replace the combined 2,056,550 square feet 
of buildings planned for industrial park use, with three buildings totaling 750,000 square feet, planned for data 
center use. The capacity analysis results from the year 2040 future conditions demonstrate the same levels of 
service with and without the Butler Drive extension and 129th Avenue improvements. The evaluation of 
projected traffic volumes, capacity, and queueing demonstrate that the additional traffic generated by the 
proposed development, combined with the removal of the Butler Drive extension and 129th Avenue, is 
anticipated to result in minimal traffic impacts to the future 2040 roadway network, with minimal impact to 
neighborhood circulation and Northern Parkway. No mitigations were recommended as the result of the 
removal of the Butler Drive extension or 129th Avenue. However, if City Council approves abandonment of the 
roadways at issue, City staff recommends that the City require that the developer construct a public cul-de-sac 
at the west end of the original Butler Drive (by 127th Avenue alignment) within twelve months from the 
effective date of an abandonment development agreement that will be presented concurrently with the 
abandonment ordinance. 
Economic/Valuation Analysis 
As part of the stipulations to this request, the applicant contracted with First Appraisal Services to complete an 
appraisal report for the valuation of the proposed roadways to be abandoned. 
The final appraisal report indicates the value of the proposed abandonment as $9,664,600; however, the 
appraisal included a “35% discount for assemblage” (page 59 of the appraisal report) or $1,100,400. The 
discount for assemblage does not apply in this case as it is understood the request for the roadway abandonment 
is to assemble the land to the adjacent parcels (APN 501-45-986 & APN 501-45-985), so the appraised value of 
the abandonment, not including the discount, is $10,765,000. In addition, the Dysart Rd project includes certain 
improvements related to Butler Drive, the cost for these improvements is estimated at $50,000. 
To ensure a fair payment to the Northern Parkway Partners and the City of El Mirage, the owner has agreed to 
compensate the Partners for the actual cost of design, land acquisition and construction in the amount of 
$8,000,000. The owner has also agreed to compensate El Mirage to cover the value of the abandoned roads in 
the amount of $3,279,000. The total amount to be paid by the owner is $11,279,000 which exceeds the 
appraised value and additional cost related to improvements to Butler Drive included in the Dysart Road 
project.  In addition, Owner will cover the costs of constructing a public cul-de-sac at the east end of Butler 
Drive. 
If the request for abandoning the roadways is approved, then additional cost will be saved as road maintenance 
and street lighting usage will not be required. 
 
Compliance with Arizona Revised Statutes 
Pursuant to A.R.S. § 28-7202 and 28-7208, if the City Council determines that the subject roadways are not 
necessary for public use, and the City has or will receive consideration that the Council believes is 
commensurate with the value of the roadways, the City Council may abandon the roadways to abutting property 
owners.  Upon review of the abandonment application and careful consideration of the traffic impact study and 
valuation analysis, City staff believes this roadway abandonment request meets the statutory requirements and 
recommends that the City Council proceed with approving the same.
