SUMMARY:  On September 20, 2004, the District Board approved the Technical Advisory Committee’s (TAC) recommendation to use General Plan build-out numbers to project future water needs.  Since that time, the TAC members have provided the District with their build-out numbers.  Once the build-out numbers were received (Exhibit 1-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 1-B), District staff compiled the attached future water needs estimates (Exhibit 1-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 Water Demand Committee will review the long-term water needs estimate by the Policy Advisory Committee (PAC) prior to consideration by the Board.  Most TAC members reviewed their build-out submittals with their governing bodies before the information was submitted to the District.  The September 26, 2005 joint PAC/TAC meeting is intended to provide one more opportunity for oversight before the numbers are forwarded to the Water Demand Committee.

 

RECOMMENDATION:  The PAC should discuss the draft water needs estimates and provide direction for further refinements and/or a recommendation to the Board. 

 

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:

  1. Historical average actual use by type of use based on Cal-Am consumption reports;
  2. Use reasonable estimates based on “average” land use densities;
  3. Use maximum potential density;
  4. Limit future demand estimates to existing legal lots of records as of January 1, 1997 (the date used in the previous legal lot studies);
  5. Estimate future needs based on potential development as allowed by the current General Plans;
  6. Other alternative methods.

 

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.  After reviewing previously used methodologies (Exhibit 1-D), 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 Monterey staff representative on its recommendation to combine a trend analysis with the general plan build-out projections to estimate the long-term water needs.

 

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. 

 

On August 3, 2004, the TAC reconvened with the recommendations from the PAC and their City Councils. Monterey County, Carmel-by-the-Sea, Del Rey Oaks and the MPAD were not represented at the meeting, although Carmel had submitted its position prior to the meeting.  On a motion by Pacific Grove and second by Sand City, the TAC voted to recommend to the Board of Directors that the methodology for estimating future water needs be based on the each jurisdiction’s general plan build-out numbers, and that District staff would apply the District’s water use factors to those general plan numbers.  The City of Monterey continued to raise its concern that if the needs assessment is very high, based on general plan build-out, any water supply project sized to meet that need would be targeted for controversy in the community.  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.  As most jurisdictions had not provided information on second units, a breakout of secondary housing units was requested at the April 2005 TAC meeting.  Jurisdictions were asked to provide the secondary unit information by the end of April to have the information included in the final long-term water needs estimate.
