Introduc�on

The City of Mercer Island, Washington is seeking proposals from qualiﬁed vendors to implement a

Parking Enforcement System. The City desires to select a vendor that can deliver a secure, scalable, and

conﬁgurable Parking Enforcement System that integrates with exis�ng City systems and supports license

plate recogni�on (LPR) enforcement, mobile ﬁeld opera�ons, and virtual permi�ng (op�onal but

preferred).

Background

The City of Mercer Island, Washington is located on Lake Washington between the Ci�es of Seatle and

Bellevue in King County. The City encompasses an area of approximately 6.5 square miles. Since the

City’s incorpora�on in 1960, Mercer Island has gained a reputa�on for its unique iden�ty consis�ng of

high-quality residen�al areas, preserved parks and open space, and miles of developed shoreline. The

City provides a full range of municipal services to its approximately 25,000 residents, including public

safety, public works, parks and recrea�on, community planning and development, and youth and family

services.

The City oﬀers �me-limited (non-paid) parking, paid parking managed by ParkMobile, and a restricted

parking district managed by physical permits. The City’s prior parking enforcement contract ended in

2025 and the hardware associated with the expired contract is no longer in working condi�on. Parking

enforcement is currently conducted manually and infrac�ons are issued using a handheld �cke�ng

device.

Sound Transit announced the East Link Extension segment between the South Bellevue Sta�on and

Interna�onal District/Chinatown Sta�on will open on March 28, 2026, along with the new Mercer Island

Sound Transit Sta�on. The opening of the East Link Extension is expected to increase demand for

parking, and the need for parking enforcement, in Mercer Island’s Town Center area.

Scope of Work

The City requests proposals for a comprehensive and scalable parking enforcement solu�on that

improves compliance, eﬃciency, accuracy, security, and customer service while reducing administra�ve

burden and opera�onal costs. The selected vendor shall provide technology, equipment, so�ware,

implementa�on services, training, and ongoing support necessary to support modern parking

enforcement opera�ons for the City.

The desired solu�on should support end-to-end parking enforcement for the City’s parking enforcement

program. The selected vendor will deliver a product that integrates with exis�ng City systems and

supports license plate recogni�on (LPR) enforcement, E-chalk capabili�es, mobile ﬁeld opera�ons,

virtual permi�ng (op�onal but preferred), and integrates with law enforcement and municipal court

records management systems.
