Project Description

The Cornish Plains Reservoir project included the design and construction of a new zoned earth embankment dam to support downstream water management needs. The reservoir serves as a storage and augmentation facility with a capacity of 3,500 acre-feet, providing additional flexibility for managing water resources within the irrigation system.

The project required a comprehensive approach from initial site investigation and engineering design, through permitting and construction. Services included geotechnical investigation, material testing, preparation of the design report, construction drawings and specifications, and coordination of required permits.

Our support continued through the bidding and construction phases, including preparation of bid documents, construction contract coordination, construction oversight, and final certification.
