What Cities Should Require From Parking Technology Vendors

Cities do not purchase a parking platform in isolation. They depend on it to support residents, field staff, courts, transportation operations, finance, public records, privacy, and continuity.

A solicitation should therefore define the outcomes and protections the city needs while leaving room for vendors to demonstrate a credible approach. Requirements must remain testable after award.

The most important question is not whether a proposal says the right words. It is whether the delivered architecture, configuration, evidence, and operating practice make those commitments real.

The contract should identify who owns operational data, case evidence, configuration, derived information, analytics, and audit records. It should prohibit undisclosed secondary use, sale, sharing, and model training.

The city needs timely access in documented, usable formats without unreasonable fees. Vendor support access should be scoped, approved, logged, time-limited, and visible to the city.

• Data inventory: List every category collected, generated, derived, or received.
• Purpose limitations: Restrict use to explicitly authorized municipal services.
• Location and subprocessors: Disclose hosting, support, and downstream providers.
• Export rights: Provide complete data, configuration, history, and audit evidence.
• Deletion: Define event-driven schedules and verification across backups and replicas.

Security questionnaires and certifications are useful but do not replace architecture review. Cities should understand identity, authorization, encryption, segmentation, administration, software supply chain, monitoring, vulnerability management, incident response, and recovery.

Privacy requirements should cover minimization, retention, sharing, notice, individual recourse, and configuration governance. For Washington ALPR systems, vendor technical controls and limits on configuration changes are statutory concerns, not optional preferences.

• Use least privilege and strong authentication for every human and machine identity.
• Separate customer environments and administrative duties.
• Protect keys, secrets, audit logs, exports, and support tools.
• Set remediation timelines based on exploitability and service consequence.
• Require prompt incident notice, evidence preservation, cooperation, and corrective action.

A statement that a platform “has APIs” is insufficient. The city should evaluate whether interfaces cover the required workflows, use understandable models, support change, and can be operated without custom intervention from the vendor.

Require documented APIs, event delivery, test environments, version policy, rate and service expectations, structured errors, replay protection, and contract tests. The city should own the integration requirements connecting enforcement to payments, permits, courts, finance, identity, and reporting.

Cities should be able to determine who accessed information, why, what they changed, what they exported, and whether the system followed retention and sharing rules.

Require immutable or tamper-evident records, synchronized time, searchable events, role and purpose context, configuration history, export monitoring, and delivery into city oversight tools.

Washington requires agencies to obtain third-party ALPR audit data and retain it. A vendor should demonstrate how the city can retrieve that evidence continuously, not only after an incident.

Parking technology may generate notices, payment experiences, portals, documents, evidence views, and hearing requests used by the public. Requirements should cover Section 508 or applicable accessibility standards, plain language, mobile access, assistive-technology testing, language support, and non-digital channels.

Vendor demonstrations should include error, correction, refund, appeal, and accommodation scenarios—not only a successful payment or citation.

Availability percentages do not explain how a service behaves during a network failure, compromised credential, regional outage, bad deployment, payment interruption, or vendor business disruption.

• Define recovery-time and data-loss objectives by workflow.
• Require tested backup, restoration, failover, and safe offline procedures.
• Document support severity, response, escalation, and communications.
• Measure third-party dependencies and single points of failure.
• Run joint exercises before launch and at regular intervals.

The Federal Acquisition Regulation describes modular contracting as acquiring technology in successive, interoperable increments to reduce risk and make change manageable.

Cities can apply the same principle by accepting independently useful capabilities: payment validation, a court filing interface, an officer workflow, or reconciliation. Each increment should be evaluated through working software, representative data, user testing, security and accessibility evidence, and service measures.

Payment milestones should reflect accepted value and resolved critical defects rather than documents submitted or hours consumed.

A city’s service must survive a vendor transition. Require open or documented formats, current configuration and architecture records, city access to repositories where appropriate, knowledge transfer, migration assistance, and deletion certification.

Test export and restore during the contract rather than waiting for termination. A theoretical export that cannot recreate relationships, evidence, audit history, and active-case state is not portable.

• Set transition-assistance scope, timing, rates, and service levels.
• Prevent contract terms from blocking the city’s use of its own information.
• Preserve continuity for active citations, payments, hearings, and appeals.
• Revoke vendor access and verify deletion after transition.
• Retain the evidence required to demonstrate compliance and final reconciliation.

A strong parking-technology procurement creates enforceable conditions for a trustworthy public service. It connects vendor promises to architecture, controls, evidence, acceptance, and operations.

Cities that require data control, secure interoperability, auditability, accessibility, resilience, modular delivery, and portability can innovate without surrendering accountability.
