SUMMARY: On September 20, 2004, the District Board approved the Technical Advisory Committee’s (TAC) recommendation to use land use jurisdictions’ General Plan build-out numbers to project future water needs for the Monterey Peninsula. Since that time, the TAC members have provided the District with their build-out numbers. Once the build-out numbers were received (Exhibit 3-A), the TAC met regularly to develop water use factors for the various types of uses anticipated at build-out. After reaching consensus on water use factors (Exhibit 3-B), District staff compiled the attached future water needs estimates (Exhibit 3-C) using (1) the recommended factors, (2) a “contingency” of 20 percent to cover unanticipated water needs or upgrades from current restrictions, and (3) water needs associated with “paying back” residential retrofit credits allowed by MPWMD Ordinances No. 70 and No. 90. (Ordinances 70 and 90 allowed a jurisdiction to “borrow” against the next water allocation.) The County’s residential water needs include the TAC-recommended adjusted residential factor that takes into account the County’s larger lot sizes. The result of the effort is an estimated long-term water need of 4,545 acre-feet to satisfy the build-out projections of the jurisdictions.
The
Policy Advisory Committee (PAC) met jointly with the TAC on September 26, 2005
and unanimously endorsed the TAC’s recommendation. The only change PAC requested was to insert a
footnote in the future water needs table to clarify that the 4,545 figure is in
addition to existing demand. Early in
the process, staff had requested water needs based on the current housing
element of each jurisdiction’s General Plan.
However, as the housing elements expire in 2007, information available
at this time will be outdated before a water supply project is on line. Therefore, staff recommends discussing water
supply phasing in 2007 when the next edition of the housing elements are
completed.
RECOMMENDATION:
The Water Demand Committee should
review the long-term water needs estimate and provide a recommendation to the
Board regarding the long-term water needs estimate developed by staff and the
TAC.
BACKGROUND: On February 2, 2004, the Board held a workshop to consider long-term water needs. At that meeting, staff was directed to place a Consent Calendar item on the February 19, 2004 Board meeting agenda to request that the Technical Advisory Committee provide a recommendation on a methodology for projecting future water needs. At the February 19, 2004 Board meeting, the recommendation was approved, and the TAC was given 90 days (until the May 27, 2004 Board meeting) to submit its recommendation. As part of the background provided to the TAC, the following alternatives were suggested for consideration:
On March 15, 2004 as part of its discussion on near-term water supply projects, the Board again requested the Technical Advisory Committee (TAC) and Policy Advisory Committee (PAC) to make recommendations to the Board on the formula to use to determine each jurisdiction’s share of any new allocation. The Board also asked if there should be an MPWMD Community Reserve, and if the Federal Government should be added as a new jurisdiction. The latter questions remain unanswered.
The TAC began reviewing
alternatives for projecting long-term water needs at its April 6, 2004
meeting. The consensus was to use each
jurisdiction’s general plan as the basis for establishing water needs, with the
District applying its factors to the general plan totals to calculate the water
requirements. Contemplation of actual
needs versus build-out needs was also discussed, including an oral presentation
by the City of
On May 4, 2004, the TAC continued its discussion on a common methodology. At this meeting, the TAC heard a proposal from Michael Waxer, a member of the public who had contacted several TAC members. Mr. Waxer’s proposal suggested viewing long-term water needs from the “bottom up” versus the normal “top down.” Using the proposed Moss Landing desalination plant as the example, Mr. Waxer’s process would move away from “allocation” thinking and would develop a methodology that would be looked at like a utility, with CEQA impacts being reviewed in the General Plans of the Jurisdictions. Mr. Waxer proposed that a Project EIR and a Program EIR could be completed with this concept in mind. Jurisdictions would determine land use needs and the District would provide the water needed to reasonably accommodate the land uses. The Project EIR would reference the total water needed for the long term, based on build-out, and the Program EIR would address an incremental process that would eventually get to build out. Two-year planning windows were suggested, with the actual production being adjusted to correspond to actual need.
The TAC members agreed that any project should be submitted for environmental review only once. Members questioned the ability to determine what the long-term demand would be and how to present it to policy makers. The TAC agreed that the PAC should be consulted to provide policy direction on establishing the method for determining potential long-term needs.
A joint TAC/PAC meeting was held on June 1, 2004 to discuss the development of a common methodology to estimate future water needs. The PAC was asked to respond to the following questions:
1. Does the PAC agree that the General Plan Build-Out should be the basis for long-term water needs projections?
2. Should this number be adjusted with a trend analysis of past permits issued?
3. Do the PAC and TAC want to establish a set of assumptions that will be applied to every jurisdiction’s water needs estimates (i.e. should we use only 30 percent of underdeveloped lots versus 100 percent at build-out)?
4. Should the TAC provide intervals (of 2-3 years) of water toward the projected build-out?
Consensus among the PAC members was that the methodology should be based on general plan build-out projections and the District’s water use factors. The PAC members agreed to submit this recommendation to their governing bodies for consideration and then to provide direction to the TAC members.
The following summarized remarks were made by respective jurisdictions representatives in response to the questions shown above:
On August 3, 2004, the TAC
reconvened with the recommendations from the PAC and their City Councils.
The motion was adopted on a vote of 4 – 0.
On September 20, 2004, the District’s Board of Directors approved the Technical Advisory Committee’s recommendation on the methodology to determine long-term water needs. Between September 2004 and January 2005, the TAC compiled the build-out numbers and submitted the information to the District. Submissions from all jurisdictions were received by February 2005.
Over the past eight months, the Technical Advisory Committee (TAC) has been meeting to determine the water factors to be applied to the General Plan build out information submitted to the District. Factors for Single-Family Residential, Multi-Family Residential and Second Units have been discussed and consensus reached.
