UWMP Notice of Preparation, March 10, 2016

March 10, 2016

[Name_F] [Name_L][Organization][Address][City], CA [ZipCode] Dear [Title] [Name_L]:

California Water Service (Cal Water) is committed to providing safe, reliable, and high-quality water utility service in our Bear Gulch service area. At Cal Water, one of our top priorities is ensuring that our customers have a sustainable supply of water for decades to come.

With that in mind, we wanted to take this opportunity to let you know that we are updating our Urban Water Management Plan (UWMP) for this service area. This UWMP is reviewed and updated every five years pursuant to the Urban Water Management Plan Act, and will be completed by July 1, 2016. Our UWMP is a foundational document that supports our long-term water resource planning to ensure our customers have adequate water supplies to meet current and future demands.

Proposed revisions to our 2010 UWMP will be made available for public review, and we will be holding a public hearing, during which the updates for the 2015 UWMP will be discussed. The draft 2015 UWMP and the date, time and location of the public hearing will be available on our web site in a few weeks at www.calwater.com/conservation/uwmp. A hard copy of the draft UWMP will also be available at our Bear Gulch Customer Center located at 3525 Alameda De Las Pulgas, Suite A, Menlo Park, CA 94025. If you have any questions about the UWMP for this service area, please contact Michael Bolzowski, Cal Water Senior Engineer, at (408) 367-8338 or e-mail [email protected].

Sincerely,

Scott WagnerDirector of Capital Planning & Water Resources

Dear Ms. Parks and Mr. Meachum,

Pursuant to California Water Code, Division 6, Part 2.6, Sections 10610 through 10656, California Water Service is in theprocess of preparing the required 2015 update of our Urban Water Management Plans. These plans are required to beupdated every five (5) years for each of our services areas (Districts). As you know our Bear Gulch District provideswater service to the City of Menlo Park.

The purpose of this communication is to solicit your assistance in reviewing and advising us with respect to one of thekey elements of the plan, which is the development of a growth forecast for our district. This growth forecast isconducted based on growth in each customer service classification applicable to a particular district, which typicallyinclude:

• Single family residential

• Multi-family residential

• Commercial

• Industrial

• Government (City or County parks, median strips, landscaping and schools)

• Dedicated Irrigation (rare)

• Other (temporary construction meters)

The forecasted growth rates are combined with a demand per service factor applicable to each customer class todetermine the future water demands for the district. These growth factors are adjustable and we want to review themwith you so that we are consistent with anticipated growth that your planning efforts forecast. If adjustments arenecessary we can do them now and avoid conflicts and confusion later in this process.

Some specific information regarding our approach to forecasting customer service growth is detailed as follows:

• Residential – Typically two residential customer service categories represent the vast majority of theservice counts as well as subsequent water sales or demand in our districts. Cal Water considers bothsingle family and multi-family residential services independently as individual classes, but combinesthem together in order to assess population growth and housing unit growth. While we use historicaltrends in the establishment for the growth rates for these two customer classes, we also analyze censusdata for population and housing factors and compare our forecast results for these two parameters with

2

available data from City General Plans, as well as County Economic Forecast data and Regionalgovernment association forecasts as a reality or appropriateness check of our results.

• Commercial & Industrial – Historical trend is a key influence in this customer class, however where wehave seen negative trends in recent years for these categories due to the economic downturn, wetypically employ either a zero rate of growth or a small, reasonable positive rate of growth. We havealso undertaken during the last ten years some reassessment of customer service classifications that hasresulted in reallocation of some customer service accounts between various classes. This reallocation,which included commercial, industrial, multi-family residential and in some cases government services,has made the analysis of growth a bit more difficult.

• Government – Growth trends are generally parallel to that of the residential sector, so we verify thatour rate of grow is not dramatically out-of-sequence with the overall community.

• Other – The use of temporary-assigned construction meters varies considerably from year to year, andcan represent considerable water demand. In this case, we select a growth rate that is stable, yetreflects the overall growth of the community.

We have included with this communication a set of tables and graphs (see attachment) that illustrate the parametersthat influence the growth forecast as currently set up for this district. These include:

A. The historical and projected service data in both graph and table formB. The 2000 and 2010 Census data for the districts service areaC. Housing projection chart comparing Cal Water’s forecast (always in red) with those from other organizationsD. Population projection chart comparing Cal Water’s forecast (always in red) with those from other organizationsE. Table of population and housing values along with multi-family residential unit density and persons per housing

unit density that are employed in this forecast effort.

Please note that the 2015 data, which we need to include in our finished forecast, is not yet final, and some minorfluctuation of these values is possible.

Please examine these documents to determine if you concur with our forecasted housing and population numbers. Itwould be greatly appreciated if you could, by September 11, 2015, provide us with an indication of your support or inthe case you do not agree with our forecast a reason why and the appropriate rate or growth pattern that we shouldemploy. If I do not hear back from you by the end of business (EOB) on the above date I will assume that you concurwith our forecast.

If you need a more detailed explanation of these numbers or want to review them with us please feel free to contact meat (408) 367-8340 or by email at [email protected].

Thank you for your assistance in this effort.

Respectfully,

Thomas A. SalzanoThomas A. SalzanoWater Resource Planning Supervisor
