Document Description
The California Department of Fish and Game is executing a Lake and Streambed Alteration Agreement pursuant to Section 1602 of the Fish and Game Code to the Project applicant. Caltrans proposes the following activities: Replacement of the existing bridge on SR 46 where it croses the Estrella River which is currently a 39 foot wide, 290 foot long four span bridge will be replaced with a new 40 foot 6 inch wide, 307 foot long two span bridge. The existing bridge would be removed first. Working from the bridge deck, an excavator with hoe-ram attachment would break the concrete free from the steel and then the steel girders would then be removed. The east abutment will be removed and re-compacted before beginning construction of the new bridge. The new bridge would be constructed using cast-in-drilled-hole (CIDH) piles. Some construction equipment will need to enter the channel, but work will not be done in the wetted portion of the channel. The Project will require cutting, 11 Fremont's Cottonwood, 7 red willows, and 1 valley oak. Vegetation would be cut to ground level with roots left intact for most of the area. After remoal of the vegetation, clean fill would be placed to create a level work area. Upon project completion the fill would be removed down to the orginal grade level. Rock slope protection would be placed at each abutment (2,045 cubic yards at the western abutment and 6,005 cubic yards at the eastern abutment), but would not extend below the Ordinary High Water Mark.
