Pershing Avenue Stockton, CA 95203 209-946-0268 1355 Halyard Drive, Suite 100 West Sacramento, CA 95691 916-403-5900 www.ksninc.com Flood Fight History 1913-14 King Island and Bishop Tract leveed in 1913-14. Early in this period Bishop Cut between districts was made. 1997 Heavy rains during period of December 30th to January 2 nd caused river stage of more than 34' at Vernalis gauge on San Joaquin River and 21.5' at Benson's Ferry gauge on the Mokelumne River. No problems on Bishop Tract. 2005 Old Dryland Levee on Bishop Tract removed after levees rebuilt for urban development. Special Considerations Bishop Tract Pumping Stations District maintains three pumping stations as shown on map. Pump station on Bishop Cut is above 100-Year Flood Elevation. Levee Patrol Plan Bishop Tract Superintendent John Meek coordinates patrol schedule and sectors. District relies on engineering firm on contract to supply patrol members. Patrols would meet at 10100 Trinity Parkway. District anticipates needing help from City of Stockton or other agency for patrols during extended high water or flood conditions. Rio Blanco Tract District relies on engineering firm to coordinate and supply patrol members. Patrol schedule and sectors would be determined at time of event. Patrols would meet at the RD 2114 Command Post located at the west side of the district. Communications will be with cellular telephones. Lath Protocol Red – Boil/Seepage Blue – Rock Slippage White – Slope/Levee Distress Flood Contingency Options Highwater Event The general floodfight strategy will be to maintain adequate patrol and flood fight primary levees. District will coordinate levee patrol and County will coordinate action planning between district and State/Federal agencies and provide logistical support. Actions · Coordinate and monitor patrol of levees · Coordinate with City of Stockton for patrol assistance as needed · Attend meetings of Metropolitan Floodfight Unified Command at Ag Center Command Post Failure of Levee on North Side of Bear Creek upstream from Bishop Tract This scenario will lead to flood waters moving west toward Bishop Tract east of Interstate 5. The general floodfight strategy will be to place emergency berms at underpasses on Interstate 5 to prevent flooding of district and create Bear Creek Relief Cut as shown to prevent floodwaters from backing up east of Interstate 5. Actions · Place and patrol emergency berms as shown at Interstate 5 underpasses · Make Bear Creek Relief Cut once impounded waters equalize with creek water elevations · Identify additional emergency pumps to dewater district in case berms fail to prevent floodwaters from entering district and/or backing up easterly · Prepare to make Bishop Relief Cut in case emergency berms fail to prevent floodwaters from entering district. Failure of Primary Levee on North Side of Bear Creek upstream from Bishop Tract (No Interstate 5 Emergency Berms or failure of Interstate 5 Emergency Berms) This scenario will lead to flood waters moving west into Bishop Tract from the east side of Interstate 5. The general floodfight strategy will be to make Bishop Relief Cut and install emergency pumping station to dewater district while protecting interior of primary levees. Actions · Make Bishop Relief Cut · Identify and place additional emergency pumps to dewater district · Protect interior of primary levees · Establish emergency access plan to King Island and Empire Tract using primary levee crown on south side of district. Failure of Levee on Reclamation District 2042 (Bishop Tract) This scenario will lead to flooding of Bishop Tract up to, and possibly east of, Interstate 5 on east side of district. The general floodfight strategy will be to prevent movement of floodwaters east of Interstate 5, and install emergency pumps to dewater district. Actions · Place and patrol emergency berms at Interstate 5 underpasses as shown on map · Repair break · Protect interior slopes of primary levees · Identify and install additional emergency pumps to dewater district · Establish and maintain access to RD2029 (Empire Tract) and RD2044 (King Island) by primary levee crown on south side of district · Monitor for increased seepage behind levees of adjacent districts Failure of Levee on Reclamation District 2114 (Rio Blanco) This scenario will lead to flooding of Rio Blanco Tract. The general flood fight strategy will be to protect interior of primary levees and install emergency pumping station to dewater district. Actions · Repair break · Protect interior slopes of primary levees · Identify and install emergency pumps to dewater district · Maintain access to district via Rio Blanco Rd bridge at southwest corner of district Delivery Points and Supply Staging Areas Pre-Planned Delivery Points DP-01 Paradise Point Marina – Bishop Cut & Disappointment Slough 121°25’4.00”W 38°02’44.66”N DP-02 Spanos Business Park – Eight Mile Road & Interstate 5 121°22’28.03”W 38°03’22.52”N DP-03 Agricultural Barn East of Bishop Cut 121°24’51.80”W 38°04’36.26”N Supply Staging Areas SA-01 Paradise Point Marina – Bishop Cut & Disappointment Slough 121°25’4.00”W 38°02’44.66”N SA-02 Agricultural Barn East of Bishop Cut 121°22’28.03”W 38°03’22.52”N Survey Information Basis of Elevations Elevations are based on the North America Vertical Datum of 1988 (NAVD88) 100-Year Flood Elevations Source: 1992 USACE Sacramento-San Joaquin Delta Hydrology Special Study Contours Elevation Source: 2007 DWR LiDAR Levee Crown Elevation Source: 2011 KSN Levee Profile Survey (Bishop Tract) 2007 DWR LiDAR (Rio Blanco Tract) Tactical Plans – (Preliminary Engineering Designs) P.E.D.’s have not been prepared for RD 2042 and RD 2114. For tactical information/actions refer to the Flood Contingency Options text box. Dewatering Plan RD 2042 If Bear Creek Relief Cut has been made – Relief cut will remain open to allow impounded waters to exit City of Stockton east of Interstation 5 as river returns to normal elevations. Once flood waters will no longer drain through relief cut, the cut will be repaired along with breach(es). Upon closure of breaches and relief cut, place emergency pumping station on levee at site shown for flood dewatering. If Bishop Relief Cut has been made – Relief cut will remain open to allow impounded waters to exit district as river returns to normal elevations. Once flood waters will no longer drain through relief cut, the cut will be repaired along with breach(es). Upon closure of breaches and relief cut, place emergency pumping station on levee at site shown for flood dewatering.
