FROM: Planning- Engineering- Operations Committee
SUBJECT: Summary Minutes of the Planning- Engineering- Operations Committee Meeting
The Planning- Engineering- Operations Committee held a meeting on May 12, 1998. Present were
Directors Arthur Korn, Sterling Fox and staff members Michael Payne, Lee Cory, Chuck Gray,
and Ken Vecchiarelli. The following items were discussed by the committee.
1. Well Water Distribution Study. Michael Payne, Assistant General Manager, presented a
staff report on methods to achieve the goal of producing 75 percent of the District's water
demands from ground water sources. Items discussed were Orange County Water
District's method of calculating ground water percentages for land within their boundary
verses the District's over all water requirements, cost differentials between ground water
and import water, and the impact of annexation fees on the economics of expanded use of
ground water. An agenda report considering this issue will be presented to the Board at a
future date.
2. 36 Inch Richfield Road Pipeline. Chuck Gray, Engineering Manager, presented a staff
report on the status of the 36 inch Richfield Road pipeline project. Items discussed were
the status of the plans and specifications, coordination of pipeline construction with City
of Placentia street improvements at the rail road crossing, and the need for this pipeline as
a replacement for the District's aging 26 inch pipeline. An agenda report considering this
issue will be presented to the Board at a future date.
3. Expanded Sewer Inspection Services. Michael Payne, Assistant General Manager,
presented a staff report on expanded sewer inspection services. Staff discussed methods to
identify sewer connections that require backwater valves to prevent sewage problems due
to inadequate elevation differences between the property served and the up- stream
manhole. The requirement of backwater valves is within the Building Code of the city
having jurisdiction. Proactive methods to assist the District's customers with complying
with this building code issue were reviewed. Staff will keep the committee advised with
the progress of this issue.
4. Via Lomas De Yorba West Pipeline Failure. Chuck Gray, Engineering Manager,
presented a staff report on the Via Lomas De Yorba pipeline failure. District forces
repaired a crack in the body of the pipe that was located between joints. Due to the nature
of the crack, staff requested a geological review of the street and slope to determine if hill
slippage was the cause of the pipeline failure. The letter report provided by Kleinfelder,
Inc. indicates that soil slippage is the cause of the pipeline failure. Staff has
communicated this information to the City of Yorba Linda. In addition, staff has isolated
this pipeline to prevent further damage should there be additional earth movement. Staff
will keep the committee advised as the situation evolves.
