About this file
This internal zoning plan, sections, and details drawing specifies construction requirements for Phase I of the BF Sisk Safety of Dams (SOD) Modifications project. The project includes building shear keys and stability berms for the dam embankment and modifying the spillway to address issues with select foundation materials, reduce safety concerns, and ensure water supply deliveries in the event of seismic activity. The drawing provides material placement control points, reference drawings, notes on dimensions, contours, zoning limits and details, specifications for geotextiles and drain pipes, and other requirements for internal zoning of the existing embankment and construction of the new spillway conduit. It will guide construction work by the Bureau of Reclamation to enhance dam safety as part of the BF Sisk SOD Modifications, Phase I project.

NOTES
1. All dimensions are in feet unless otherwise noted.
2. For survey information, see (805-208-60101).
3. Contour interval is 5 feet.
4. See material placement control points for internal zoning limits.
5. Gravel surfacing not shown. See (60125) and (600126) for typical details.
6. Chimney zones to extend up to El. 480.
7. Width of 9B chimney to vary due to geometry of excavated surface.
8. Footprint of Zone 11 chimney shown on plan. Zone 11 material to be underlain by Zone 9B material, except against spillway conduit. Zone 9B shall be placed with a minimum horizontal thickness of 6 feet between excavated surface and Zone 11.
9. Geotextile shall be placed to separate Zone 11 from Zones 1 and 8. Refer to specifications.
10. Material zones to continue up and wrap around spillway conduit.
11. Drain pipes to extend parallel to spillway. See (60124) for spillway drain details.
