4S Ranch by Newland Communities is a 2,900-acre community adjacent to Rancho Bernardo. Upon completion, it is planned to feature 4,715 single-family homes and townhomes. This was the first arch storm drain project approved and used by San Diego County. The storm drain system was a critical path item. By working multiple fronts, Hydro-Arch was […]

Hydro-Arch constructed the walls of the Wave Pool Equipment Building utilizing the shotcrete process. Fixed road elevations created severe size constraints for the storm drain system. Hydro-Arch’s engineer ES2 designed a low, wide arch structure that met the heavy flow requirements and fit easily within the size constraints. Location: Henderson, NV Owner: Splash Management, LLC Structural Engineer: Aquatic Development Group, […]

Additional parking was needed for the development of a large box mall. A section of the Upper Las Vegas Wash bisected the mall property. By capping 1,200’ of this rectangular channel the property was unified and provided with additional parking. Post-tensioning the deck resulted in 27% cost savings. The channel walls were reinforced with the use of shotcrete, resulting in […]

Over 3,000 feet of 28 foot span arched culvert was required for the new Green Valley Crossing Shopping Center. As always, speed of construction was very important. The Hydro-Arch culvert system had production rates of 90 feet per day. However, the speed of construction was governed by the excavation. Almost the entire excavation had to be blasted through rock. A cold spell for several weeks required thermal insulating blankets and space […]

The Jess Ranch Marketplace built by Weingarten Realty Investors in Apple Valley, California is a 400,000 SF retail hub. Originally, the land was bisected by an existing creek. By constructing an arch culvert to accommodate the creek, the land was reclaimed for use as additional parking. This project was initially designed as a pre-cast arch culvert, and our redesign to the cast-in-place […]

Hydro-Arch designed and built the access tunnel for the very first NASCAR facility in Kern County, California in the city of Bakersfield. As a short track, it extends a little more than 2/3 of a mile while banking an extraordinary 14 degrees, one of the most severe in Nascar. The tunnel is 220’ long, 24’ wide and 13.25’ tall. It provides […]

Centex Homes was looking for a prominent feature for their new home development in Menifee, California. This bridge sits adjacent to the recreation center which is the heart of the project. It was designed to allow small boats to navigate through it with a minimum 4’ water depth. Hydro-Arch also designed two other structures in case of overflow. To extend the life of the structure and […]

A major flood control project made possible the construction of the Vegas Grand Condominium Project. The Vegas Grand project put the confluence of the Flamingo Wash and the Tropicana Wash underground, freeing above ground use for parking and landscaping. Flood waters from Flamingo Road and the site required a partially open bridge design to bring water into the culvert. This, coupled with other hydraulic requirements […]
