Document Description
The Alameda County Public Works Agency is implementing SF Bay RWQCB certified full capture systems of trash treatment control devices (TTCD) properly sized to trap particles 5mm and greater and trash debris in channel flows in the region specific 1-year, 1-hour design storm, without adverse hydraulic effects upstream. The TTCD will be Estudillo Canal between Washington Avenue and I-880 Freeway Northbound on/off ramp on Caltrans property. The TTCD will be installed on the bottom of the existing concrete lined rectangular channel. A 48' high concrete weir to direct trash debris laden low flows into the six linear trash treatment control devices will be constructed. The existing openings in the concrete flow restrictor walls downstream of the devices location will be enlarged to increase flow discharge to compensate for the potential hydraulic effects of the TTCD in the channel.
