CHAPTER I INTRODUCTION This Plan has been prepared in compliance with the mandates contained within Assembly Bill 11X. An amendment to the Urban Water Management Act, Water Code sections 10610 through 10656 wnich were added by statutes 1983, Chapter 1009, and became effective on January 11, 1984. AB 11X requires each urban water supplier to amend their Urban Water Management Plan to include a Water shortage contingency Plan, as specified. Plans are to be prepared, adopted and submitted to the Department of Water Resources by January 31, 1992. This Plan is, therefore, the requirements of AB 11X. Appendix "A". A. Preparation & Adoption of Plan This Plan was prepared by the staff of the San Dieguito Water District. A Draft Plan of the Water Shortage contingency Plan was presented at the San Dieguito Water District Board meeting on the formal document to satisfy A copy of AB 11X is included as 1 December 10, 1991 for the purpose of obtaining public comment and input from the District's Board of Directors. The final Plan was adopted by the Board of Directors of the San Dieguito Water District on January 21, 1992, by Resolution No. 92-01, included as Appendix "B". 2 . .~,_.~ .... .... c:: W l- e. <t ::I: (.) CHAPTER II WATER SUPPLY AND DEMANDS A. Supplv bv Source - For the Next Three Years Historically, imported water purchased from the San Diego County Water Authority (CWA) has accounted for 65% of supplies. Local water in Lake Hodges accounted for 35% of supplies. Due to drought conditions in 1977-78, imported water made up 94% of supplies. In 1985-86, due to extremely wet conditions, Lake Hodges water accounted for 59% of total supplies. Under normal conditions, the figures of 65% imported water and 35% local water could be used for planning purposes. However, for "Worst Case" scenarios it should be assumed that no local water would be available. Table No. 1 shows the "Worst Case" supply projections. 1989-90 is the Base Year and assumes no local water is available and imported supply deliveries are reduced by 50%. The reader is referred to CWA' s contingency Plan for their supply projections. 3 TABLE NO. 1 SAN DIEGUITO WATER DISTRICT "WORST CASE" SUPPLY PROJECTIONS* (AF /YR) Source 1990-91 1991-92 1992-93 1993-94 Local o o o o CWA 4493.1 4541.1 4589.1 4637.1 Total 4493.1 4541.1 4589.1 4637.1 *Assumes no local water available and imported deliveries reduced 50% B. Normal Demand Reauirements As identified in the 1990 San Dieguito Water District (SDWD) Master Plan, annual water consumption has been increasing at a rate of about .12 MGD per year. However, agricultural demand has been decreasing and will likely continue this trend. Once accounting for approximately 20 percent of the District I s overall usage, agricul tural usage will drop to between 5 to 15 percent of the District's total water demand. Table No. 2 reflects a slight decrease in agricultural demand beginning in 1991-92 with a corresponding increase in residential demand. Currently, single-family customers account for 46 percent of overall demand followed by multi-family customers at 21 percent of demand. Figure No. 1 shows five customer classifications and the percentage of demand. 4 ~ C1 :;0 (") C r (") --I 0 C :;:: :;0 :;:: CT1 CT1 (f) ~ :;0 (") :P 0'1 ~ Z 0 r :;:: :!< ~ 0 '--' C 0 r r ~ -0 rrl --I a z CT1 Gl I :!< 0 :;0 ..., '--' Ul (") C ~ (") r'1 :;:: ~ z -1 -0 --I 0 r r'1 ~ -< C1 /'. r'1 ::2: /'. -.-J N 0 hj a :P :!< .., H 0 ~ -1 G1 :!< C rrl c ~ Ul ::D ::0 r'1 t'l OJ 0 Z -< 0 - (") (f) c -1 H Ul ::D --I 0 - :;:: () r'1 -1 :;0 i" ;'-j Ul Z C1 r r'1 ..., ~ :;:: r -< ~ .j:>. 0'1 a :!< '--' 5 (") r ~ Ul Ul '1 -< CO 1..0 I 1..0 o TABLE NO. 2 SAN DIEGUITO WATER DISTRICT DEMAND REOUIREMENTS (AF/YR) SOURCE 1989-90 1990-91 1991-92 1992-93 1993-94 sinale-familv 4089.5 4133.7 4268.7 4313.8 4359.0 Multi-familv 1867.0 1887 1907.3 2019.2 2040.3 Aaricultural 1422.5 1437.8 1362.3 1285.0 1298.4 commercial 889.0 898.6 908.0 917.8 927.4 Landscape .622.3 629.2 636.0 642.5 649.2 Total 8890.3 8986.3 9082.3 9178.3 9274.3 C. population Trends The latest growth forecast available from SANDAG shows an annual growth rate of approximately 1.2 percent. The current SDWD Master Plan, in determining the ultimate water demand, also took into account the growth control provisions of the 1989 city of Encinitas General Plan. (It is likely that growth within the SDWD will experience an increase at a slower rate than most of San Diego County). See Table No.3. SANDAG's Series No. 8 Growth Forecast based on the 1990 census for Special District's will not be available until late Spring or early Summer of 1992. 6 WI ..,.. ii' ~~";':";l III o . , " .

CHAPTER III EMERGENCY CONDITIONS The San Dieguito Water District has several different water sources, which gives the District multiple options to weather emergency conditions. The R.E. Badger Filtration Plant, located in Rancho Santa Fe, is jointly owned by San Dieguito Water District and Santa Fe Irrigation District. Unlike most water agencies in San Diego county, the filtration plant gives San Dieguito Water District the flexibility to be supplied water by San Diego county Water Authority's (SDCWA) treated and untreated pipelines. Another source of water supply is Lake Hodges. Currently, San Dieguito and Santa Fe Water District's have agreements with the city of San Diego to utilize water from Hodges when available, although the amount of water available cannot always meet 100% of both District's demands, it would definitely be invaluable if SDCWA's pipelines failed. Lastly, if the water supply shortage is primarily focused on San Dieguito Water District's system, San Dieguito currently has agreements with neighboring water district's to utilize existing interconnections. 8 A. Potential Emeraencv Conditions The 1990 San Dieguito Water District Water Master Plan evaluates several potential emergency scenarios and suggests alternatives to increase the reliability of the distribution system. Table No. 4 summarizes the discussion by identifying: 1. The likelihood of the event. 2. The probable duration. 3. The effects. 4. Mitigation options. See Appendix C, Chapter 5, Evaluation of Emergency conditions, Wat~r Master Plan. It should be noted that the mitigation measures presented in the Master Plan mostly recommend capital Improvement Projects involving upgrading the distribution system and constructing new water storage facilities. It is unlikely that these measures will be in place within the 3 year time frame of this contingency Plan. However, emergency connections and agreements are in place with neighboring Districts. 9 Q ~ _. n ~ " , il , p' -... g " " m Q = -. ~ " , ~ , o -. ~ ~ n 0 o , , , " ~ -< n " - ~ - ~ o ;; o ~ - o o ."

Emeraencv connections and Aareements with other Aaencies The physical interconnection of the District facilities with those of adjacent water agencies increases system flexibility and provides alternate sources of water to the District during emergencies and short-term planned system shut down. The District currently has system interties with two of its neighboring water agencies; the Olivenhain Municipal Water District and Santa Fe Irrigation District. A third intertie is planned with the Car1sbad Municipal Water District. These interconnections are for the purpose of transferring limited amounts of water between agencies during emergencies and short- term planned, or unanticipated water system outages. Currently, however, no agency adjacent to the District has local water supply storage that can satisfy more than a fraction of its own demands, much less provide additional supplies to another agency, other than for short-term. 11 ...-. _._-,_..__._---"----~--- ;, .... c:: W l- e. <t ::I: (.) --~-- CHAPTER IV WATER SHORTAGE - MITIGATION OPTIONS A. Increase Supplies Since SDWD relies on the San Diego County Water Authority for the majority of its water supply, any increase in supplies would have to come from that agency and the reader should refer to CWA's contingency Plan. B. Demand RedUctions In order to mitigate a water shortage, SDWD may implement any of the following programs or methods to reduce demands. Water allotments by customer class. Specific use prohibitions. Prohibitions against wasteful uses with penalties. An increasing block rate schedule. Penalties and/or charges for excessive use. Mitigation measures for new connections. Plumbing fixture retrofit programs. Incentives for conservation, including rebates. Public information and education programs. Some of these options are discussed and described in more detail in the following sections. 1. Determination of Water Manaaement staaes During water shortages, the District will impose water uses regulations in stages previously adopted by ~ ..., Resolution No. 91-20. (See Appendix "D") The stages are a sequential, regulatory program of increasingly more stringent prohibitions on the use and amount of water 12 delivered within the District. When the District declares that a particular water management stage is in effect, the regulations contained in the declared stage are to be complied with by all persons using water delivered by the District. The District will monitor the proj ected supply of water, both local and imported, and the demand for water. In conjunction with those agencies providing water to the District, it will be determined when a particular water management stage is required in order for the District to mitigate water shortages. Water Shortages occur when the amount of water available from all sources is below the amount ordinarily available. Total usage in the Base Year 1989-90 is the amount of water "Ordinarily Available." stages are determined by comparing the amount of water available to the District with the amount "Ordinarily Available". 2. Mandatorv Prohibitions The District has declared, and prohibited, that at no time shall water be wasted or used unreasonably. Unreasonable uses of water include, but are not limited to, the following: a. Allowing water to leave a customer's property by drainage onto adjacent properties, public or private roadways or streets due to excessive irrigation and/or neglect. b. Failure to repair a water leak. c. using water to wash down sidewalks, driveways, parking areas, tennis courts, patios or other paved or hard areas. 13 Each water management stage also contains prohibitions on certain water use practices, such as; specific landscape watering times, washing of vehicles, filling of swimming pools, operation of ornamental fountains, etc. Violation of prohibitions may result in receiving a warning notice, fines, restriction of service or the discontinuance of service. (See Appendix "D") 3 . Allocations The allocation system adopted by the District is intended to be flexible and fair to all customers taking into account the impacts on business, employment and quality of life. The system recognizes those customers who have conserved and requires those who have used more water to reduce their consumption by a larger percentage. Each residential account receives an allocated amount of water plus a percentage of previous use. The allocation is based on the District's estimate of average residential use. The additional percentage of previous use accounts for seasonal variations in consumpticn. This additional percentage will change depending on the Stage of required reductions. Adjustments to a customer's allocation can be considered for such reasons as: having more than four permanent people in a single-family home (more than two in a multi-family unit), where no consumption history exists, medical reasons, etc. Customers who exceed their allocation are subject to financial penalties and possible restriction of service. 14 The District determined that for residential customers usage reductions up to 20% (stages 1 - 4) could be obtained through a combination of public information programs, education programs, incentive programs and the inverted block rate schedules. To obtain more than a 20% reduction (stages 5, 6 & 7) the allocation program would be implemented. See Table No.5. TABLE NO.

Excess User Fees Any customer who violates a water management allowance when stage 5 or greater is declared to be in effect, will pay an Excess User Fee in accordance with the following schedule: a. First billing period after the effective date of this resolution will be considered an adjustment period during which no excess user fee will be imposed for water usage above one's allocation. b. First Occasion After Adjustment Period: 3 x the highest unit water rate charge for the amount used in excess of the allowance for that customer. c. Second Occasion After Adjustment Period: 6 x the highest unit water rate charge for the amount used in excess of the allowance for that customer. d. Subsequent Occasions: 9 x the highest unit water rate charge for the amount used in excess of the allowance for that customer. Funds received as Excess User Fees shall be separately accounted for. The funds shall first be used to pay for the costs of acquiring excess water and administrating the provisions of these regulations. Thereafter, the funds shall be used to fund conservation programs approved by the District. S. Water Rates In establishing a principal consideration new water rate of the District schedule the was to obtain 16 rates that were reasonably proportionate to the cost of providing water service. In addition, the new rates compliment the District's Emergency Water Management Plan as one of the ways to encourage water conservation. See Table No.6. Rate schedules are designed to meet average conditions for groups of customers having similar service requirements. The groups of customers within the District are classified as: 1.) Single-family Residential, 2.) MUlti-family Residential, 3.) commercial, 4.) Landscape and 5.) Agricultural. An acceptable practice for encouraging water conservation for residential customers is the implementation of an inverted block rate structure, where by the unit cost of water increases as the usage of water increases. To obtain conservation from non-residential customers, whose usage patterns and amounts vary, an allocated amount of water is determined for each customer and usage above that amount is charged at a higher rate. The Lifeline or Baseline rate is the lowest rate charged to residential customers. The quantity of water charged at this rate is considered water used mostly inside the home (20 HCF bi-monthly for single-family and 12 HCF bi-monthly per dwelling unit for multi-family. 1 HCF = 748 gallons). The Baseline is not adjustable to individual customer conditions. While most customers will use more than this amount for both inside and outside usage, there are those customers whose consumption is 17 always less than the Baseline. There are those customers too, who have reduced their consumption so that part of the year their usage is at or near the Baseline amount. The Baseline was established to ensure that low-income customers could afford water for basic use, to recognize customers who have made an effort to reduce their consumption and as an incentive for other customers to conserve. The next block of water used above the Baseline is considered discretionary interior and exterior use and the highest block is considered non-essential or excessive exterior use.

LEGISLATIVE COUNSEL, DIGEST AB 11, as amended, Filante. Urban water management plans. (1) Existing law requires every w::ban water supplier serving water directly to customers to',. not later than December 31, 1985, prepare and adopt an urban water management plan. Existing law authorizes an urban water supplier indirectly providing water to customers to adopt an urban water management plan or to participate in urban water management planning. This bill would, instead, require every urban water supplier, whether serving water directly or indirectly to customers, to prepare and adopt an urban water management plan. as prescribed. (2) Existing law requires the urban water management plan to include a prescribed description of water supply deficiencies. This bill would delete that provision and would require the urban water management plan to include an urban water shortage contingency plan, as specified.

This chapter evaluates several potential emergency scenarios and suggests alternatives to increase the reliability of the distribotion system. Particularly relevant to the current study are those emergency scenarios that are mitigated by an ade- quate supply of treated water storage. Note that an evaluation of the district's raw water supply and treatment facilities is beyond the scope of this study; hence emergency conditions af- fecting these facilities are discussed in general terms only. More thorough investigations are recommended to evaluate the reliability of the district's water supply facilities. Much of the following discussion is summarized in Table 5-1. SCENARIO ~: DROUGHT ;..i . ~ Periods of drought are a common occurrence in Southern Califor- .nia. During these periods, the water quality of the district's local supply from Lake Hodges can be expected to diminish to .the extent that its water is unusable. Fortunately, the district's access to the SDCWA's second aqueduct has historica~ry provided a reliable source of both raw and treated water. The stated goal of the SDCWA, however, is to supply peak week demands to its mem- ber agencies; it is the responsibility of those agencies to 5-1 " ., rn o H ~ .:: Z ~ t) rn .-1>- I t) Il'IZ ~ ~ t!l ..:l~ CQ~ .:::.: ...~ ..:l .:: H ...

It is also uncertain that the SDCWA will be able to achieve its water supply goals for future demands. Thus, a drought might cause the SDWD difficulty in meeting its peak demand requirements. Ideally, the district should develop raw water storage that is supplied by the SDCWA aqueduct. Lake Hodges, while a valuable source of raw water supply to the District, is currently solely dependent on local water production. A large imported raw water reservoir could provide long term emergency storage, seasonal storage, and storage necessary to smooth out peaking in the treatment plant's demand. since the treatment plant is owned and operated in association with the Santa Fe Irrigation District (SFID), it is aavisable to study this option in greater detail in conjunction with the SFID. , It should also be noted that the Olivenhain Municipal Water Dis- trict (OMWD) is currently seeking agencies interested in par- ticipating in the Mount Israel Project, which potentially in- cludes a 24,000 AF raw water reservoir and treatment plant. This project could provide the district with a reliable source of water. The reservoir is well situated to supply the Badger Filtration Plant either through the SDCWA aqueduct or through an independent transmission main. If the SDWD is interested in this project, OMWD will probably need a commitment to participate within a year. It is recommended that the district initiate a detailed investigation of the feasibility of participating in the Mount Israel Project. ". ...;~ Finally, the city of San Diego and the SDCWA are considering providing a raw water aqueduct supply for Lake Hodges. Under this concept, the lake would be filled during late winter for use . in the high demand summer months. The district I s participation in this effort is encouraged. 5-2 SCENARIO 2: RAW WATER SUPPLY FAILURE Failure of the district's raw water supply could take several forms: failure of either or both of the SDCWA's pipelines in their second aqueduct, or failure of the Lake Hodges supply, due to flume failure, water quality degradation, pump station failure, etc. As independent events, the failure of the Lake Hodges supply or the filtered SDCWA pipeline will not have a major impact on the supply to the SDWD; the surviving raw water pipeline (with a turnout capacity of 24.6 mgd) should be able to provide the district's needs. If the raw wateripipeline failed, much of San Diego county would " experience a water shortage. This shortage could not be met by the filtered water pipeline alone, and the SDWD has no pre- emptive rights to SDCWA's filtered water during an emergency. Hence, the consequences for the SDWD could be. analogous to a failure of both aqueduct pipelines. Also, an earthquake might easily cause the catastrophic failure of both pipelines. Finally, since both aqueduct pipelines share a common alignment, the failure of a single pipeline might wash out the remaining pipeline. Should any of these events occur, the raw water supply for both the SDWD and the SFID would be limited to the Lake Hodges flume capacity, currently rated at about 14 mgd (the raw water pump station at the San Dieguito reservoir is rated at 18 mgd) . This would mean a loss of approximately 50% of the district's current maximum day demand until the SDCWA aqueduct can be repaired, estimated to require about one month. , ~,:;: In order to mitigate this event, four recommendations for further study are made. First, the district, in conjunction with the SFID, should investigate making improvements to the Lake Hodges supply system to increase its capacity. The district should also consider encouraging or participating with the city of San Diego - .~ 5-3 to provide an aqueduct.connection for Lake Hodges. ,.in the Mount Israel Project should be explored. creasing the district's treated water storage would effects of a short term loss of raw water supply. Participation Finally, in- alleviate the ~..- "- SCENARIO 3: WATER TREATMENT PLANT FAILURE Assuming that the Badger clearwell were to remain.in service, the failure of the Badger Filtration Plant, either for temporary service or due to a major equipment failure, will have little im- pact on the district's water supply. The SDCWA filtered water aqueduct connection should be able to supply the district I s needs. '- SCENARIO 4: BADGER CLEARWELL FAILURE Because the Badger clearwell is bifurcated, planned maintenance can be conducted with little interruption to the distribution system supply. However, there is no clearwell bypass line; any water delivered to the distribution system, including SDCWA fil- tered water, must pass through the clearwell. In an emergency, the clearwell can be bypassed by draining the San Dieguito reser- voir raw water. line and using it to connect the SDCWA filtered water line to the 54 inch treated water transmission main. In such a scenario, the settling basins can be used to equalize flow demands, but this process would be difficult and require inten- sive effort to coordinate. Currently, the clearwell is the exclusive storage for the 409, 410, and 520 zones. The 345 and 240 zones can be served for a limited time from the Balour reservoir, but a loss of the clear- well will mean that water supply to the upper zones will be severely limited. 5-4 Although a clearwell failure as described above is an unlikely event, the construction of a clearwell bypass line is recom- mended. Also, additional local storage should be constructed and a pump station to supply the elevated pressure zones should be considered. Finally, emergency connections with neighboring agencies should be maintained and additional connections con- structed if future opportunities develop. SCENARIO 5: TRANSMISSION MAIN FAILURE Consideration has been given to a loss of transmission capability at several different locations. '- 54" Joint Transmission Main :~. The jointly owned 54" transmission main . leading from the Badger Filtration Plant to the San Dieguito Reservoir is the only fil- tered water connection between the plant and both the SDWD and the SFID. When this line is taken out of service, the 30" San Dieguito Reservoir raw water line can be drained, disinfected, and used to bypass the 54" line. For scheduled maintenance on the 54" line this procedure is adequate, but because it is cum- bersome and time consuming, it is less satisfactory when the 54" line fails in an emergency. Also, the smaller line severely limits the amount of water available to both water districts. Reliability and transmission capability would be enhanced by the construction of a redundant transmission line paralleling the ex- isting 54" line. This issue should be investigated further as one of the many issues affecting both the SDWD and SFID. " 5-5 I I High Pressure Transmission Mains '- The SDWD operates two high pressure transmission mains that serve the 520 pressure zone: a 30" and 36" steel line. Bec.ause there are no reservoirs for the 409, 410 and 520 pressure zones within the district, these two lines must provide peak hour flows to these zones, as well as providing maximum day demands to the 345 and most of the 240 zones. Under current demand conditions, and with the satisfactory operation of the low pressure transmission line, the failure of either of these transmission lines can be tolerated reasonably well. As system demands increase, however, and if the low pressure main is abandoned, the failure of either of the high pressure lines will put severe stresses on the remaining line. Both mains share a common alignment for roughly 9000 ft in En- cinitas Blvd. A simultaneous failur~ of both of these lines would have a severe impact on the entire SDWD. All flow to the 409, 410, and 520 zones would be limited to whatever was avail- able through emergency connections with the OMWD. The demands of the 345 zone could be met for a time from the Balour reservoir, but district's ability to fill this reservoir would again be limited to the capacity of OMWD's emergency connections. The 240 zone could still be supplied through the low pressure main, but without support from the 345 zone, areas in the north end of the district will experience degraded system pressures. The reliability of the distribution system could be enhanced with the construction of additional local storage, the construction of redundant transmission capacity, or the construction of a pump station to boost locally stored water for use in the higher pres- sure zones. 5-6 Low Pressure Transmission Main The 30" low pressure transmis~ion main is the oldest of the transmission mains and experiences the most frequent failures. with the current arrangement of pressure reducing stations (PRS's) throughout the district, such failures cause a slight pressure drop (on the order of 5 PSI) in the 240 pressure zone, but computer analyses indicate that they place undesirable stress on upstream pressure zones. The construction of additional local storage would reduce this effect. SCENARIO 6: LOCAL STORAGE FAILURE currently, the ~nly active water storage within district bound- aries is the Balour reservoir. While planned maintenance can be scheduled for periods of low water demand, a failure of this reservoir during a period of high demand would place a tremendous burden on the water distribution system with a corresponding drop in water pressure. Emergency connections with other water dis- tricts help reduce this burden. system reliability would be in- creased with the construction of additional local storage. ,'- ,. SCENARIO 7: DISTRIBUTION MAIN FAILURE The failure of individual distribution system mains is a rela- tively common occurrence due to localized const=uction and the ~ging of pipes. The primary defenses against these failures are the looping of system pipes and the provision of adequate isola- tion valves.

A general water supply shortage due to increased demand or limited supplies; B. Distribution or storage facilities of the Metropolitan Water District of Southern California ("MWD" hereinafter), the San Diego county Water Authority ("CWA" hereinafter), or other agencies, become temporarily or permanently inadequate; or C. An unexpected disruption or major failure of the supply, storage or distribution facilities of MWD, CWA, or other agencies. The District also finds and determines that: D. The conditions prevailing in the San Diego County area and the District require that available water resources be put to maximum, beneficial use; E. The waste, unreasonable use, and any unreasonable method of use of water must be prevented; F. Encouraging the conservation of water with a view to the maximum reasonable and beneficial use thereof is in the interest of the people of the District; G. There have now been four consecutive years of drought conditions in the State of California; H. The california Department of Water Resources has informed MWD that it will be necessary in 1991 to reduce deliveries to municipal and industrial contractors; 1. The California Department indicated that additional deliveries may be necessary; of Water reductions Resources has in scheduled J. MWD projects that the Colorado River water supply for MWD - 1 - in 1991 may ~e reduced by approximately 20 percent; K. In the most recent twelve-month period, water demands on the MWD system exceeded 2.60 million acre-feet which exceeds the supplies presently available to MWD by approximately 1.0 million acre-feet; L. By its Resolution 8291, MWD created the Incremental Interruption and Conservation Plan to address potential shortages of imported water in a continuing drought; M. The Incremental Interruption provides for staged responses conditions; and to Conservation Plan continuing drought N. MWD implemented stage 5 of the Incremental Interruption and conservation Plan effective March 1, 1991; O. Exceptional dryness in the normally wet season continues to substantially worsen the water supply outlook; P. MWD implemented stage 6 of the Incremental Interruption and Conservation Plan, calling for a mandatory 50% reduction in water use to take effect April 15, 1991; Q. The current drought conditions have arisen by reason of current and foreseeable shortfalls in local as well as imported supplies of water; R. CWA has declared the existence of water shortage emergency condition; and S. CWA has established procedures to preserve and allocate available water supplies. NOW THEREFORE, the Board of Directors of the District resolves as follows: SECTION ONE: That the "Emergency Water Management Regulations" is adopted to read as follows: See Attachment "A" SECTION TWO: That Resolution No. 91-13, adopted March 26, 1991, is hereby rescinded. SECTION THREE: - 2 - This resolution is effective July 9, 1991.

(714) 753.1252 i ,n April 12, 1991 Victor Graves Engineering & Planning Supervisor San Dieguito Water District 59 East 0 Street Encinitas, CA 92024 Dear Victor: We have completed the requested analyses to develop water rate schedules for the various stages of water reduction set forth in the District's proposed Water Conservation and Emergency Water Management Program. The results of our analyses are presented on the attached exhibit. [n designing the alternative water rate schedules, we have endeavored to maintain the same base rate for at least some minimum quantity of residential usage. Thus, low volume residential users who diligently work to reduce their usage in accordance with usage restrictions will continue to pay the same price per unit of water. This means that they will see a reduction in their water bills. We have also structured the rates such that an average residential user who reduces his or her usage commensurate with the required reductions will basically receive the same water bill. Users who do not reduce consumption can expect significantly increased bills. We have not incorporated the penalty provisions of the District's Resolution into the rate schedule. Therefore, the charges for excess use only vary from $2.39 per HCF under Stage 1 to $3.00 per HCF under Stage 7. However, these rates are to be multiplied by 3,6, and 9 respectively as called for in Section 20.60.080 should customers exceed their allowances under Stages 5,6 or 7. Thus, the penalty could be as high as $27.00 per HCF under Stages 6 or 7 if a customer continues to exceed his or her stated allowance. :-~I The rates for each alternative have been designed to recover the . required level of revenue assuming no water will be sold at the excess use rate. For Stages 1,2 3 and 4, the requirement is $5,229,000. For Stages 5,6 and 7 the amount was reduced to approximately $4,7000,000. We assume that all customers will reduce their usage as required. Any revenues from penalties can then be used by the District to pay surchages to the County Water Authority and/or be used for water conservation programs. In the attached exhibit, the rates for Stage 1 are the original ones we developed during our study. The rates for Stage 3 are the ones shown in our report. The rates for Stages 5,6, and 7 are the same as those c;,A .. ~ictor Graves San Dieguito Water District Page 2 April 12, 1991 ..'1 presented at the March 26 Board meeting, except for the excess use charges. As discussed above, those charges have been reduced from the levels indicated at the March 26 meeting because the Board opted for the 3,6,9 penalty provision. This means that the excess use charge need not be the penalty rate. Rates for Stages 2 and 4 are extrapolations. We feel confident that they would generate sufficient revenues. For Stages 1,2,3 and 4 we would recommend that the District develop individual allocations for only non-residential users. For Stages 5,6 and 7 all users should have allocations. We believe that usage reductions up to 20 percent are obtainable from residential customers through a combination of a good public relations program and the proposed inverted block rate schedules. To obtain more than a 20 percent reduction from residential users, utilities have found it necessary to implement allocation programs. Because all our rate designs assume certain changes in customer behavior, it is.likely that actual revenues may vary from projected levels by as much as 5 to 15 percent. Variance towards the high side is considered more likely for the higher stages of water reduction. It will simply be too difficult for some users to cut back 30, 40 or 50 percent. For the lower stages of reduction, it would be possible to have higher revenue shortfalls if customers overreact to the requirements. " We hope that the information presented herein meets your needs. We are prepared to present the results at the April 16 Board meeting. Very truly yours, tc Enclosure Boomhouwer ., , ~ ~ ~ ~ ~ SAN OlEGUITO WATER OlSTRICT 59 EAST" 0" STREET ENCINITAS, CALIFORNIA 92024 (619) 753-1145 " NOTICE OF PUBLIC HEARING BY SAN DIEGUITO WATER DISTRICT REGARDING PROPOSED REVISION OF DISTRICT WATER RATES NOTICE IS .HEREBY GIVEN that the Board of Directors of San Dieguito Water District will conduct a public hearing regarding a proposed revision of District water rates.
