Title

Ostwald Waterline Replacement Project

Description

CDFW has executed Lake and Streambed Alteration Agreement No. 1600-2016-0064-R3, pursuant to section 1602 of the Fish and Game Code to the Project Applicant, Edward Lambing/San Jose Water Company. The project is the replacement of approx. 1,575 linear feet of raw water intake pipeline within Los Gatos Creek. The pipeline originates at the Ostwald Dam intake facility to an existing pipeline connection located approx. 1,500 feet downstream (to the north). The existing 30-inch wrapped steel pipeline will be removed and replaced in the same alignment, to the greatest extent possible, with a new 30-inch ductile iron pipeline with polyethylene encasement. An open trenching technique will be used to extract and replace the existing pipeline. The width of the trench will be approx. 52 inches, and the depth will be determined by the grade of the existing pipe but will be approx. 4 feet. Project construction will result in approx. 0.05 acres of temporary impacts to wetlands located within the creek, and 0.82 acres (1,500 linear feet) of temporary impacts to the creek bed and bank. All trees within the project area will be retained. Minor pruning of lower hanging limbs, particularly within the staging area, may be necessary.
