EXHIBIT B
RIGHT OF WAY (ROW) ASSISTANCE
The Parties have determined that acquisition of additional property to allow for the completion of the Project is
for the benefit of the public.
To streamline the process for appraising and acquiring land rights for the Project in unincorporated County and
reduce duplicative effort and cost to the taxpayers, the City, in consultation with and approval from the County,
will retain Outside Counsel to represent the Parties as necessary to acquire properties from owners within
unincorporated Maricopa County for the Project. The Parties agree that the retained Outside Counsel will jointly
represent the Parties with respect to the acquisition of acquired properties from owners within unincorporated
Maricopa County.
1. County responsibilities:
1.1 Maricopa County Real Estate Department (MCRED) staff will review the City’s proposed project
scope to ensure understanding of the Project and how it impacts unincorporated Maricopa County
residents. A MCRED representative may attend Project meetings and public meetings as
requested by the City.
1.2 Permit Outside Counsel retained in accordance with this agreement to jointly represent the
County, the City and the Town in the acquisition of the rights of way required for the Project upon
the City’s request (ROW Assistance) and if Outside Counsel determines it to be necessary,
execute a Joint Representation Agreement for the acquisition of properties under this IGA.
1.3 When a property to be acquired extends into multiple jurisdictions, the Parties shall confer and
attempt to develop a plan whereby all the needed property can be acquired in a single action,
rather than have separate litigation proceed at the same time against the same owner.
1.4 If the City is unsuccessful in acquiring the required right of way by agreement from an owner,
Outside Counsel, under the joint direction of the City and the County, may proceed to acquire the
property by the power of eminent domain with County named as plaintiff with the following
stipulations:
1.1.1. County will communicate with the City and Outside Counsel appointed to represent the
County in the acquisition of the property.
1.1.2. Outside Counsel shall keep County and City apprised of the status of each condemnation
action for which Outside Counsel has been retained. Status updates should occur monthly
and be sent via email to MCRED Director and MCRED ROW Supervisor.
1.1.3. Outside Counsel shall communicate directly with the Maricopa County Attorney’s Office
(MCAO) and the City Attorney’s Office concerning the status of any condemnation action
and shall provide the MCAO and City Attorney or designee an opportunity to review and
comment on a draft of the complaint and any amendments to the complaint or other filing.
1.1.4. Outside Counsel shall copy the MCAO and the City Attorney or designee on significant
pleadings filed in the case, including the complaint, answer, status reports, scheduling
orders, motions, responses and similar briefs, as well as copies of any significant rulings
from the Court.
1.1.5. The joint defense and common interest privileges shall apply to all communications
between MCAO and the City Attorney’s Office concerning any condemnation action filed

Docusign Envelope ID: B01F3971-264D-859F-833D-DDD42765EF5F
or contemplated to be filed under this IGA.
1.5 Invoice the City, based on supporting documentation, monthly for County employees’ time as it
relates to the Project
1.6 Issue all necessary permits to the City for the Project, and related work conducted within the
County’s jurisdictional boundaries, at no cost to the City.
2. City responsibilities:
2.1 Provide remote meeting options to City’s Project Meetings to facilitate attendance by MCRED
team members.
2.2 Perform all duties as the lead agency for the Project, including without limitation, responsibility
and liability for the design, all activities necessary to complete the acquisition of right of way,
