Geocon performed a geotechnical investigation for the proposed Junior Lifeguard Facility located in the city of Newport Beach. The project consists of replacing the old portable trailers which the program previously used with a new permenant facility. The Junior Lifeguard Program is designed to teach the youth about the ocean and aquatic safety, with a focus on educating them to recognize potential hazardous conditions associated with an aquatic environment.

The structure is roughly 4,895 square feet and features a training auditorium, bathrooms, locker rooms, a first aid center, administrative offices, and a shaded deck.

Located on the beachfront, the site is subject to potential geologic hazards such as liquefaction, lateral spread, tsunami, and flooding, along with challenges posed by a high groundwater table affecting construction techniques. Our analysis revealed significant liquefaction risk in the shallow, loose alluvial soils, with signficant lateral spread. To address these conditions, we recommended a cost-effective mat foundation supported by soils improved through Rapid Impaction Compaction, avoiding the high costs of deep foundations required to resist liquefaction and lateral spread.

Following our geotechnical investigation, the City of Newport Beach retained Geocon to further continue work throughout construction. We performed observation and testing services during preparation of the building pad and during grading of paving subgrade, backfill of utility trenches, and placement of base materials & asphalt-concrete paving.
