Tesoro Zone II and Zone B Water Facilities - Rough Grading and Storm Drain Improvements

Butier Engineering, Inc. provided third-party construction management and inspection services for the Tesoro Zone II and B Water Facilities project, which provides operational and emergency water supply to a portion of the Esencia Village planned community (Planning Area 2). The project site is located in Rancho Mission Viejo (an unincorporated area of Orange County) located northeast of the City of San Juan Capistrano and two miles north of the Chiquita Water Reclamation Plant within Chiquita Canyon.

The Zone II and B Water Facilities project consisted of three separate construction contracts. The first contract (C-1767C) consisted of the rough grading of an access road and reservoir site, earthen detention basins, storm drain system installation, habitat restoration, and miscellaneous surface improvements and appurtenant work. The earthwork and major drainage facilities precede all other activities, including the installation of domestic water (DW) and recycled water (RW) pipelines in several locations and a 3.0 MG steel DW storage reservoir and 2.0 MG RW steel storage tank.
