ETM Pipeline Removal in San Juan Creek Project, MNWD Project 2016.001
Document Type
MND - Mitigated Negative Declaration

Document Description
Note: Extended Review per lead An approx 180-lf segment of an abandoned 30-in diameter ETM that extends across the channel bed of San Juan Creek is proposed to be removed by MNWD. The existing 30-in diameter DIP is encased in reinforced concrete and due to erosion of the channel bed in the area, an approx 30-ft long segment of the encasement is exposed. As proposed, MNWD's contractors would cut the reinforced concrete encasement at the toe of the concrete slope creek channel walls and remove the approx 180-lf segment of 30-in diameter DIP and reinforced concrete encasement from within the creek channel.
