Following our successful expansion into the Inland Empire in August of 2017, we are proud to announce that the Inland Empire team has a new location! Previously located in San Bernardino, our new office has moved west to Ontario, where we can continue to serve the Inland Empire, and surrounding areas, with professional land surveying services.

The Ontario office is Guida’s 4th Southern California location and 6th location in California. Guida has the privilege of working on a variety of projects in the Inland Empire including, but not limited to, the East Valley Water District Sterling Natural Resource Center, RCTC I-15 Railroad Canyon Interchange, RCTC 91-15 Express Lane Connector, RCTC I-15 Express Lanes Project Southern Extension, SBCTA I-10 Mt. Vernon Interchange, and SBCTA Redlands Maintenance Facility.

In addition to stand alone projects, Guida also provides on-call land surveying, mapping and right of way engineering services to Caltrans District 8, San Bernardino County Department of Public Works, City of Menifee, City of Fontana, City of Moreno Valley, and East Valley Water District, to name a few. Our Inland Empire team looks forward to continuing to add to our diverse portfolio of project experience, and being a part of this rapidly growing region of Southern California. metropolitan area.

Although our team is still unpacking boxes, they are excited to share their new “home” with Guida family and clients in the near future.
