Flood Fight History

1913-14 King Island and Bishop Tract leveed in 1913-14. Early in this periodBishop Cut between districts was made.

1997 Heavy rains during period of December 30th to January 2nd caused riverstage 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 BishopTract.

2005 Old Dryland Levee on Bishop Tract removed after leveesrebuilt for urban development.

Special Considerations

Bishop Tract Pumping StationsDistrict maintains three pumping stations as shown on map. Pump station on BishopCut is above 100-Year Flood Elevation.

Levee Patrol Plan

Bishop TractSuperintendent John Meek coordinates patrol schedule and sectors. District relies onengineering firm on contract to supply patrol members. Patrols would meet at 10100Trinity Parkway. District anticipates needing help from City of Stockton or other agencyfor patrols during extended high water or flood conditions.

Rio Blanco TractDistrict relies on engineering firm to coordinate and supply patrol members. Patrolschedule and sectors would be determined at time of event. Patrols would meet at theRD 2114 Command Post located at the west side of the district.

Communications will be with cellular telephones.

Flood Contingency Options

Highwater EventThe general floodfight strategy will be to maintain adequate patrol and flood fightprimary levees. District will coordinate levee patrol and County will coordinate actionplanning 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 TractThis scenario will lead to flood waters moving west toward Bishop Tract east ofInterstate 5. The general floodfight strategy will be to place emergency berms atunderpasses on Interstate 5 to prevent flooding of district and create Bear Creek ReliefCut 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 sideof Interstate 5. The general floodfight strategy will be to make Bishop Relief Cut andinstall emergency pumping station to dewater district while protecting interior of primarylevees.

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, Interstate5 on east side of district. The general floodfight strategy will be to prevent movement offloodwaters east of Interstate 5, and install emergency pumps to dewater district.

Actions

· Place and patrol emergency berms at Interstate 5 underpasses as shown onmap

· 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 strategywill be to protect interior of primary levees and install emergency pumping station todewater 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

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 2042If Bear Creek Relief Cut has been made – Relief cut will remain open to allowimpounded waters to exit City of Stockton east of Interstation 5 as river returns tonormal elevations. Once flood waters will no longer drain through relief cut, the cut willbe repaired along with breach(es). Upon closure of breaches and relief cut, placeemergency pumping station on levee at site shown for flood dewatering.

If Bishop Relief Cut has been made – Relief cut will remain open to allow impoundedwaters to exit district as river returns to normal elevations. Once flood waters will nolonger drain through relief cut, the cut will be repaired along with breach(es). Uponclosure of breaches and relief cut, place emergency pumping station on levee at siteshown for flood dewatering.
