Parking Structure Design Competition

Project Overview

The new Downtown Ontario Parking Structure provides convenient, community-focused parking to support the Civic Center and surrounding amenities. Designed as both a practical facility and a civic landmark, the structure incorporates the City’s iconic sun-and-mountain logo on its eastern façade, creating a subtle, layered artwork that reflects local pride. Sustainable materials, open-air screening, and horizontal sunshades ensure natural ventilation, reduce glare, and enhance pedestrian scale. Thoughtful design elements - including clear pedestrian and vehicle entries, a prominent elevator tower, and integrated bicycle storage - make the structure safe, accessible, and welcoming, while harmonizing with nearby public buildings and future developments.

Community Access

The Downtown Ontario Parking Structure addresses an immediate need for convenient parking, serving residents, visitors, and patrons accessing the Civic Center and nearby amenities.

More than just a parking facility, the structure doubles as a symbol of civic pride. Its eastern façade features the City’s sun-and-mountain logo, rendered through layered aluminum screens and sunshades to create a subtle, elegant landmark.

Thoughtful Design and Integrated Connections

Sustainable, low-maintenance materials and a transparent façade allow natural light and ventilation, while horizontal sunshades reduce nighttime glare and maintain a welcoming pedestrian scale.

Vehicular and pedestrian entries are designed in harmony with surrounding civic buildings. A prominent elevator tower and stair elements provide clear visibility, security, and accessibility, complemented by bicycle storage and covered walkways.
