OPERATIONS AND MAINTENANCE PLAN
for the
KERN RIVER SOUTH LEVEE WEST OF BUENA VISTA ROAD
PURPOSE:
In exchange for certain riparian properties on the Kern River, the City of Bakersfield entered into
an agreement with Tom Carosella Properties and Coleman Homes, Inc. which required the City
of Bakersfield to construct an earthen levee on the south bank of the Kern River from the vicinity
of the Stockdale Highway/Kern River bridge to a point approximately one mile southwesterly.
This levee will permit Coleman Homes, Inc. to build residential and commercial development on
the vacant lands to the south. The Federal Emergency Management Agency (FEMA) requires
the responsible agency, the City of Bakersfield, to have an officially adopted maintenance and
operation plan for the levee.
A) OPERATION PLAN: This project is located on a reach of the Kern River extending
5000 feet west of the Stockdale Highway Bridge. The City now has jurisdiction and
maintenance obligations over the first westerly 1800 feet measured downstream from
the Stockdale Highway Bridge. During most years, the Kern River is dry in this area,
since the water is diverted for irrigation, The City has an existing agreement with the
State of California Department of Water Resources to maintain the elevation of the bed
of the River from the 1800-foot point downstream of the Stockdale Highway Bridge
upstream to the Manor Street Bridge. This agreement will be extended to cover the
additional channel invert maintenance to a point 5000 feet below the Stockdale Highway
Bridge. In addition to the City complement of labor and heavy equipment, a standby
heavy equipment contractor is retained on an annual contract with a 24-hour notice
clause to assist in this work. The contract with the Contractor will be extended to cover
the additional 3200 feet and will be utilized to make any major levee repairs.
CLOSURE DEVICES: No closure devices exist or are proposed in the project area.
FUTURE INTERNAL DRAINAGE SYSTEMS: The future internal drainage systems will
be established in accordance with the regulation of the City of Bakersfield. These
gravity facilities, maintained by the City of Bakersfield, will be designed with streets and
drainage lines carrying storm waters to excavated sumps to receive the storm waters.
The sumps are designed for receiving storms of 100-year frequency.
AUTOMATIC FLOOD WARNING SYSTEMS: No automatic flood warning system exists
or is proposed.
B) JURISDICTION AND RESPONSIBLE PERSONNEL: The maintenance and repair of
this levee facility is the responsibility of the City of Bakersfield, Kern County, State of
California.
The personnel responsible who have the authority to order emergency work are as
follows:
Patrick E. Hauptman, Water Superintendent, City of Bakersfield (661) 326-3715
Florn Core, Water Resources Department Director, City of Bakersfield (661) 326-3715
Gene Bogart, Water Resources Manager, City of Bakersfield (661) 326-3715
C) INSPECTIONS: The inspector shall keep a written log of the inspection activities and
reports. The levee shall be routinely patrolled at least annually, after severe storms,
when the channel has been carrying water flow in excess of 500 cubic feet per second,
grass fires and for seismic events greater than M~,5. During these examinations,
erosion, vegetative cover, the 18-inch ductile iron drinking water pipeline crossing shall
be carefully examined for signs of distress. The pipeline is located approximately 30 feet
downstream from the Stockdale Highway Bridge.
D) MAINTENANCE: LEVEE REPAIR; Rills, sloughing or erosion of the slopes of the
levee shall be immediately repaired and be filled with suitable material and thoroughly
compacted to 100% of dry density as defined by ASTM D698 (Modified Proctor). After a
seismic event of M,~5 or more, any sand boils or other damage shall be immediately
repaired since the site may be subject to soil liquefaction. The standby Contractor shall
be prepared to furnish equipment and materials for immediate major repairs should
heavy damage occur. For the most severe circumstance, high river conditions, severe
seismic event, the Contractor shall have available a Caterpillar 235 excavator, a
Caterpillar 966 Loader, a self-propelled vibratory roller and a motor grader available
within 24 hours. Particular attention shall be to the 18-inch ductile pipe crossing and any
damage shall have immediate attention.
VEGETATIVE WORK AND REPAIR: A well-established sod cover over the levee will
be maintained to prevent erosion rills and sloughing and to withstand design velocities.
The vegetative material on the levee shall be carefully preserved, fertilized and re-
seeded or re-sodded as needed. Occasional spraying of brush growth with herbicides
may be required to maintain the sod cover. The work shall be performed in accordance
with CALTRANS STANDARD SPECIFICATIONS JULY 1992 DEPARTMENT OF
TRANSPORTATION STATE OF CALIFORNIA, Section 20 and the slopes shall be hydro
seeded with the following mixture: GRASSES: Hordeum 15%, Leymus 20%, Elimoides
10%, Vulpia 10%, Poa 5%, Necella p. 20%, Fesuca 20%, each applied at 1.75 Ibs/1000
SF. HYDROSEED APPLICATION The hydro seed slurry shall contain the seed as
specified above, mulch and water in the following amounts per acre: Long grain wood
fiber mulch 800 Ibs., seed as specified. GRASSES, 108 Ibs., water 300 gals/min.
Fertilizer, if needed shall be 16-20-0 or equal.
RIPRAP: Should riprap be found necessary to protect portions of levee from erosion, the
following treatment will be utilized: from CALTRANS STANDARD SPECIFICATIONS
JULY 1992 DEPARTMENT OF TRANSPORTATION STATE OF CALIFORNIA, and
may consist of non-concreted concrete debris without rebar or facing class rock. A
footing trench will be constructed at the toe of the slope and method B Placement
utilized in accordance with Section 72.503.
RODENT CONTROL: When burrowing rodent damage is observed rodent control
measures will be taken. Excavation and repair will be immediately performed.
