SUMMARY: The
Board will consider expenditure of funds to expand the previously authorized
pilot study of wells in fractured rock formations in the Carmel Woods,
Carmel Views and Aguajito areas to fractured
rock wells within the entire District. Approximately
650 wells are known to exist in the expanded study area, which includes the Carmel
Valley Upland and Miscellaneous areas (including
incorporated cities, upland Highway 68 corridor,
As explained below, the requested amount is $30,100 for consultant
assistance and equipment purchase. This
item is partially budgeted in the current fiscal year budget.
RECOMMENDATION: Staff
recommends that the Board:
Ř approve the expanded study;
Ř authorize staff to retain Hutnak Hydrologic Consultant Services for a not-to-exceed amount of $26,500 for 530 hours (Exhibit 14-A);
Ř authorize staff to purchase six automatic data loggers at $600 each for a total of $3,600; and
Ř direct
staff to present its findings to the Water Demand Committee at a future meeting
(mid-2011).
BACKGROUND: At its January 28, 2010 meeting, the Board
did not approve Urgency Ordinance No. 143 that would have temporarily suspended
receipt and processing of Pre-Applications and Applications for a MPWMD Water
Distribution System (WDS) permit that is supplied by a well drilled in
“fractured rock.” The Board referred
additional research and discussion back to the Water Demand, Rules and
Regulations Review, and Technical Advisory Committees. Ordinance No. 143 information is available
at:
http://www.mpwmd.dst.ca.us/asd/board/boardpacket/2010/20100128/20/item20.htm
The Water Demand
Committee (WDC) has been the lead committee regarding this matter. It encouraged staff to conduct a pilot study
of fractured rock wells in an area of concern and report back to the committee.
At the June 18, 2010 Water Demand Committee (WDC) meeting, staff
presented its findings, conclusions and recommendations based on a pilot
study of wells in the Carmel Woods, Carmel Views and Aguajito areas. The presentation relied on an extensive data
mining effort, primarily using a consultant, who used District, County and
State of
http://www.mpwmd.dst.ca.us/asd/board/committees/waterdemandcommittee/2010/20100618/0618agenda.htm (see agenda item 2). A
presentation on the pilot study and status update on regulations governing fractured
rock wells was also made at the Technical Advisory Committee at its August 3,
2010 meeting.
On June 18, 2010, the WDC directed District staff to develop a scope and
cost estimate to expand the pilot study methodology to fractured rock wells
within the entire District. This
information was presented to the WDC at its July 21, 2010 meeting, and the
committee recommended approval.
IMPACT ON STAFF/RESOURCES: As shown in Exhibit 14-A, expanding this effort to other fractured rock areas within the District, using the same consultant and methods, would cost an estimated $26,500 for 530 hours. The nine major tasks would take about six months to complete. The consultant rate is $50 per hour. The consultant cost estimate does not include instrumentation of selected monitor wells. Assuming six wells are found to be adequate for monitoring, another $3,600 would be needed for six automatic data loggers at $600 each. Thus, the total cost estimate is $30,100.
Given that procedures from the pilot study are already established, only 40 hours are expected for staff oversight and administration. Another 40 hours would be needed to download information from the data loggers.
The adopted Fiscal Year 2010-2011 budget includes a line item for $10,000 for fractured rock analysis (item 2-8-7). Thus, if this expanded study is approved by the Board, a mid-year budget adjustment will be needed to account for the estimated $20,100 overage.
It is noted that the General
Manager requested co-funding of the expanded study from
