Irvine Ranch Water District, On-Call Land Surveying Services

For more than 20 years, Guida has been a trusted teaming partner to the IRWD, providing land surveying, mapping, and right of way engineering on numerous improvement projects. Services have included design and construction survey support for infrastructure sewer and water pipelines, pump stations, reservoirs, marsh redevelopment, and other facility improvements.

Design services include GNSS and other control surveys, topographic surveys and mapping, boundary surveys, cadastral and title research for right of way engineering support, preparation of legal descriptions and plats, and monumentation preservation. Construction services include constructability reviews, construction computations, construction staking for pipelines, appurtenances and new improvements, as-built surveys, earthwork quantities, monumentation, and the preparation of corner records. Guida’s recent work includes:

Laguna Canyon Road Cathodic Protection and Roadway Improvements: This project included the update and replacement of cathodic protection and road improvements within the project area along Laguna Canyon Road. Guida provided design surveys which included cross sections of Laguna Canyon Road, inventory of the existing cathodic protection, water pipelines and appurtenances, construction computations and staking for the water and roadway improvements, and client coordination throughout construction.

Irvine Lake Pipeline North Conversion: This project improved the water pipelines within Jamboree and Santiago Canyon Roads to support the growing residential communities in North Irvine and Orange. Guida provided control surveys, design surveys, detailed topographic surveys, utility surveys and mapping, and digital terrain modeling. Guida also provided construction and as-built surveys on behalf of IRWD.

San Joaquin Marsh Redevelopment: This environmentally sensitive project (shown in the photo above) required field modifications and improvements to existing conditions. Guida provided control surveys, facilities aerial photogrammetric mapping and digital orthophoto production, conventional topographic surveys, quantity surveys to monitor earthwork import and export during construction, and a final as-built survey once the site modifications were complete.

Shady Canyon Road Infrastructure Pipelines: This project included the installation of 1.5 miles of sewer, reclaimed water, and domestic water pipelines within Shady Canyon Road. Guida provided control surveys, construction computations and surveys, monument preservation and perpetuation, and pre and post construction corner records.

Whiting Ranch Zone 9 Reservoir: This project included the installation of a new steel water reservoir and the associated pipelines and appurtenances at Whiting Ranch. Guida provided right of way retracements and staking for the project area, construction computations and staking, and client coordination throughout construction.

El Toro Rd Topographic Survey: On this project Guida is providing topographic surveys for improvements along a portion of El Toro Road. The project will include roughly 100’ X 50’ of surveying including curb & gutter, lane Striping, signage, valve cans, pull boxes, fire hydrants, and a portion of parking lot curb and gutter at minimum.
