(1) What assets and liabilities does the community currently have? (2) What facilities will be needed for ultimate build out? (3) How will these facilities be payed for? It can be noted in the following Chapters the three main transmission lines from the aqueduct to the service area may not have adequate capacity at ultimate build out. In addition, the service area will require a substantial amount of additional ain transmission lines and storage capacity. Squires Dam, which represents 93% of the community's storage, is dependent upon the Health Department's approval. This could become a problem should that approval be withdrawn. It could result in the expenditure of funds for either a downstream filter plant, or the construction of additional storage. Fortunately, the community has relatively little outstanding debt for water facilities. From the information submitted and estimates made, it appears approximately $1*5 million worth of new facilities will be necessary to complete the community's ultimate water system. The City has developed a Capital Improvements and replacement program which identifies it's needs, costs, and funding sources for the next 5 years. Costa Real is in the process of developing a Capital Improvement and replacement program. However, it has not proceeded far enough to identify all the service area needs, costs, or funding sources. The following is a summary of the Facilities identified in the report. COMBINED FACILITY NEEDS Facilities Cost 1. Pipeline replacement $ U,323,000 2. Storage facilities 22,255,000, 3. Transmission lines 16,3U7,000, U. Joint Operations Center 2,050,000. $i*U,975,000, ii NOTE: The following facilities may have to be constructed. 1. Additional covered storage or a filter plant if the Health Department enforces it's covered storage policy. 2. Additional transmission capacity from the aqueduct if the population and water demand develops as noted in Chapter V. 3. Steel lines in certain areas corrode faster than normal. The pipelines listed in Table 7 may have to be replaced sooner than the normal 50 year life. CAPITAL FACILITIES PLAN In order to build these facilities, it will be necessary for the community to develop a plan which would include the following elements. 1. A comprehensive community wide master water plan. 2. A facilities replacement program. 3. An immediate and long range Capital Improvement program. i*. A short and long term cash flow plan for all non- operating revenues and expenses, i.e., Capital Improvement funding. iii 5. A five year cash program for system operations. 6. A revised water rate schedule that will encourage conservation and assess cost in proportion to benefit 7. A comprehensive analysis of all non-operating charges a.) Developer contributions. b.) Connection fee. c.) Account set-up fee. 8. Capital Improvement fund sources, a.) Revenue sharing. b.) Municipal Lease backs/iNon Profit Corp. c.) Assessment Districts. d.) Revenue Bonds. e.) Grants. f.) Short term loans. g.) Standby charges. iiii CHAPTER I. PURPOSE The purpose of the report is to inventory the water facility assets of the City of Carlsbad and Costa Real Water District service areas. In addition, identify those facilities necessary to provide an adequate water supply to ultimate build out. This examination would include those facilities that will have to be replaced, either through deterioration or lack of adequate capacity. It will be the initial step in preparing a skeleton Capital Improvements and replacement program. In order to implement such a program, a long-term financial plan has to be developed to provide the necessary funding. The future development of any community is dependent upon an adequate water supply. A key ingredient in the provision of this service is a planned and funded Capital program. The foregoing items will be analyzed in an effort to provide an insight as to the community's capability in fulfilling this i Kplan. 1. "Community" is used as a collective term for the service areas of both Costa Real and the City of Carlsbad. 1-1 CHAPTER II. SCOPE OF WORK 1. Current inventory of major assets. This effort will include inspection of existing records to identify major assets, including such items as pump stations, pipelines, tanks, as well as system expansion capability. In other words, those items that are considered an asset to any enterprise type operation. 2. Facilities required to build out. This task would involve a brief overview of the gross requirements, i.e., total water delivery capability, storage, etc. to provide adequate water service for complete build out. It will not address specific sizes, location, and exact cost. 3. Capital replacement program. A list of those facilities that have to be replaced before the year 2000 will be identified, based upon existing records of each agency. I*. Long-term financial program. This effort will II-l include a review of the Capital funding requirements as determined by the Capital Improvements program. It will also include a discussion on the various financing plans available for funding both operations and Capital Improvements, along with an observation as to the appropriateness of each of those methods. II-2 CHAPTER III. BACKGROUND The City of Carlsbad has recognized a key element in it's future growth will depend upon an adequate water supply. There are two major elements in utility planning. 1. A master water plan addressing the needs of the proposed land use. 2. A suitable funding program. The development of a master water plan, in large part, is dependent upon land use planning. However/ for the purposes of analyzing the needs on a regional basis, gross water demands can be estimated and incorporated in the program. A major difficulty in developing a long range plan is determining a suitable financing plan for constructing the facilities. General Obligation Bonds, in the past, have proven to be one of the most effective low cost means of financing Public Works projects. Unfortunately, this vehicle is no longer available. The development of an alternative and equitable program has to take into consideration the nature of the area, i.e., is it developed (replacement program) or is it in a developing area (new capacity) and what is the ability III-l to pay for these improvements and who best pays for them - the developer/ land owner, water user??? The establishment of a master water plan and cost estimate is a relatively straight forward effort. However, the major policy decision is "who pays and when???". The success of any program is dependent upon this decision. Each funding plan has to be customized to meet the specific needs of the community, as there is no one universal solution to a Capital Improvement funding program. OPERATION RELATIONSHIP The Costa Real Municipal Water District encompasses a service area of approximately 20,000 acres. The District provides both retail and wholesale water service. Three major transmission lines deliver treated water from the aqueduct system to the community as noted in Plate 1. In addition, the District provides regulating and emergency storage for the entire community in its Squires Dam reservoir. The City, in turn, receives its water through five metering stations from Costa Real's system. Carlsbad pays Costa Real $16.00 an acre foot for this service. This $16.00 is in addition to the cost of the water.

METHODOLOGY Since the information contained in this report is applicable to the entire community, it was determined the Scope of Work should be developed by the staff of both agencies. The data used in this report was obtained during meetings with both staffs, as well as individual interviews, to insure accuracy and completeness. It is the intention of this report to provide the community with enough information to determine their agency's ability to provide for it's future water needs. In addition, it will identify those areas that may need more attention in order for the community to fulfill it's master water plan. It will also provide an approximate estimate of future costs for this program so adequate provision may be made for the procurement of the necessary funds. Abbreviations: 1MGD = one million gallons per day. 1ACFT = one acre foot of water = 325,830 gallons, 1 cfs = one cubic foot per second flow = kSQ gallons per minute, gpcd = gallon per capita per day. IV-1 CHAPTER V. FUTURE WATER AVAILABILITY San Diego County Water Authority With the construction of the Fifth Barrel/ the San Diego County Water Authority will have sufficient aqueduct capacity to about the year 2000. Additional facilities will be required beyond the year 2000. The Metropolitan Water District of Southern California (MWD) has a contract with the State of California for 2,500,000 acre feet of water/ per year/ which should meet the needs of Southern California until the year 2020. However, MWD will have to construct additional distribution facilities to the San Diego area prior to the year 2000. In order for the State to meet it's contractural commitment to deliver this water/ it will be necessary to construct additional water conservation facilities. One of which is the Peripheral Canal. A combination of facilities are included in the construction program to guarantee the delivery of water. V-l The Peripheral Canal/ or any other conservation structures/ will take considerable time to construct. The Central Arizona project coming online in 1985/ will obviously reduce the availability of water to MWD. In preparation of this reduction/ as well as a possible drought/ MWD has instituted their interruptible water plan which encourages member agencies to store as much water as possible in surface reservoirs or underground basins. Further/ MWD is now working with the local communities to encourage and fund waste water reclamation programs to supplement the water supply for Southern California. MWD anticipates their interruptible pricing program, coupled with waste water reclamation/ would be sufficient to carry the state through a drought period in 1985-86. However, the State of California does have to complete it's water facilities in order to guarantee an adequate supply of water to Southern California to the year 2020. The foregoing emphasizes the need for long-term storage/ water conservation and waste water reclamation, in order to meet the community's long-term commitment for an adequate water supply. V-2 CHAPTER VI. FUTURE WATER DEMAND A report "Water System, Engineering Study - City of Carlsbad 1966" ' estimated the City would have a population of 40,000 by 1980 and the average daily per capita consumption would decline from 280 gallons per day to 200 gallons per capita per day. Therefore, the City's water demand would increase from a "current 1966 usage of 3.3 million gallons per day to 8 million gallons per day in 1980". SANDAG Series V Population Study indicated the City of Carlsbad's service area has a population of 19,000. Its water consumption for 1980 was 5318 ACFT, or U.70 MGD. This equates to 2U8 gpcd. This is relatively high because it includes industrial, as well as domestic consumption. It has been estimated the City's ultimate population will be 2. 160,000 people. This projection encompasses an area of 2U,000 acres which is considered the entire planning area for the City of Carlsbad. For the purposes of this study, the 20,000 acre service area of the Costa Real Municipal Water District was used. Assuming the population density 1. Water System Engineering Study - City of Carlsbad Jack Y. Kubota/Wayne P. Li 11, January 1966. 2. City of Carlsbad Interim Growth Management Program prepared by Sedway/Cooke, May 1981. VI-i for ultimate build out Is evenly distributed/ this would result in a service area population of 133,335 people. It is anticipated the daily per capita demand may decrease due to water conservation efforts/ the use of reclaimed water, and the increased cost of water. For the purposes of this study/ 160 gpcd has been selected as a reasonable consumption. This is equivalent to a 21.33 MGD (33.1 cfs) ultimate demand. Currently, the average annual demand on the system is 11.9 MGD, or 18.U3 cfs. WATER STORAGE In planning the future needs of the community water supply system, the obvious elements are the ability to transport a sufficient amount of water from the aquaduct to the service area and operational and emergency water storage. Currently, the community can store approximately 3 weeks of average annual demand. This amount of storage is a major safety factor considering the possibility of a failure in the aqueduct system. Assuming this policy continues in the future, this would mean there would be an ultimate need of 1375 AF (acre feet) of storage. VI-2 EXISTING STORAGE CAPABILITY COSTA REAL Faci1i ty Capac!ty MG Eight Distribution reservoirs 7.3 Squires I 195.5 TOTAL 202.8 or 622.6 acre feet EXISTING STORAGE CAPABILITY CITY OF CARLSBAD Faci1i ty Capacity MG Three reservoirs COMBINED CAPACITY 210.8 or 6^7.2 AF VI-3 Approximately 93 percent of this storage is in Squires Dam. The Health Department requires all filtered domestic water supplies be retained in covered storage. Squires Dam does not meet this criteria and could be considered inadequate as per Health Department standards. Currently the District is under no order or demand to take the reservoir out of service. PIPELINE CAPACITY The service area is supplied by 3 transmission lines connected to the San Diego County Water Authority aqueduct. They are as follows: Fac?1ity Capacity 1. Tri-agencies pipeline consturcted in 1979. 20 cfs 2. ID #1 pipeline, 1957. 25 cfs 3. South aqueduct line, 1981. 1U cfs TOTAL 59 cfs delivery capabi1i ty These 3 pipelines are the basic imported supply to the service area. In addition, the City of Carlsbad has rights to 3,1*00 acre feet of ground water in the San Luis Rey River. Vl-t* Previously/ it was estimated the ultimate population will require an annual average flow of 21.33 MGD, or 33.1 cfs. Transmission lines are normally designed to accommodate maximum day (2.2 times annual average demand). In this case, that would result in a maximum day demand of 1*6.9 MGD, or 72.70 cfs. This would exceed the delivery capability of the 3 existing lines. The current maximum day demand is approximately 1*0.6 cfs. The community is only 23 percent developed. This leaves approximately 15,UOO acres either undeveloped or in agricultural production. As the community urbanizes (and there is every indication it will), the total demand for water may decrease, depending upon the intensity of development. As a general rule, as an agricultural area urbanizes to a medium density, total water demand does not change appreciably, however, peak demand begins to reduce. One fortunate aspect of the community's service area is that it can be served by gravity, thus relieving it's dependence upon mechanical pumping devices and energy. In the forthcoming years, energy will become a major component in the cost of distributing water. VI-5 CHAPTER VII. INVENTORY OF CURRENT ASSETS AND LIABILITIES - CITY OF CARLSBAD Previous reports ' have itemized the various facilities owned by the Utilities Dept. of the City of Carlsbad. The foregoing has been compiled from these reports and the City's financial records in an effort to provide information concerning the value of those assets. Table 1. The City of Carlsbad's outstanding debt is as noted in Table 2. INVENTORY OF CURRENT ASSETS - COSTA REAL The capital assets owned by Costa Real are as noted in Table 3. Table k is a summary of their outstanding debt obligations. Table 5 is a synopsis of the financial statements of both Costa Real and the City of Carlsbad for the years 1978 through 1980. It can be noted the two agencies are quite similar from a fiscal standpoint. 1. Water Service in the Carlsbad Area - Ralph Anderson & Associates, September 1979.

FUTURE CAPITAL FACILITIES REQUIREMENTS Replacement Program - City of Carlsbad The City of Carlsbad has identified 2k different pipelines that have to be replaced within the next five years. They represent an estimated replacement cost of $823,000., based on current prices. (Table 6). With construction costs escalating at 1% per month, it can be seen the foregoing estimate will increase quite rapidly. Replacement Program - Costa Real Municipal Water District Most of the District's water system is relatively new, thus replacement of old pipelines is not much of a problem. However, the Costa Real Municipal Water District has identified four major steel waterlines that have to be replaced. (See Table 7) If these pipelines were to be replaced at today's cost and existing sizes, this would amount to an expenditure of approximately $3.5 million. Since these pipelines represent the major source of water for the community, it would be prudent to set up a funding plan to replace these lines in the event of an accelerated deterioration due to cathodic corrosion problems.

Pipe sizing will be evaluated after City of Carlsbad - Water Department and District determine ultimate water requirements for City service area. 1.2 mile* of existing 20" diameter steel pipe -- constructed in 1959; this pipeline will require replacement at such time its reasonable use has been fulfilled. There is a possibility its sizing may be changed in the event the "Coastal Zone" land uses become the permanent uses. 1.3 miles of existing 27" diameter steel pipe -- constructed in 1961; this pipeline will require replacement at such time its reasonable use has been fulfilled. In the meantime, the pipeline will be paralleled by a second supply line that will be a part of the Squires Dam II expansion program. '\ that we have set out only four major pipe- ason for this lies in the fact that the that are shown on our various approved existing lines that will be replaced (steel 1 be accommodated at the "development" KUBOTA* ASSOCIATES. INC. TABLE 7 (con' t. ) Septeiiiber 8, 19bl Page 2 stages of the various properties. Uniquely, our District constructed its arterial water system in the late 1950's and early 1960's to accommodate the vast "drylands" area of the District. With intensive urbanization coming as a result of extending public sewer service to our agricultural areas, the land form is'changing dramatically, resulting in the extensive relocation and replacement of our pipe- lines. In fact, in several instances, our District has delayed pipeline projects in hopes the alignment of future streets and highways are established formally so we will not be saddled with expensive utilities relocation expenses. With this initial level of inventorying of our Capital projects, we shall be working in earnest to bring the entire program to a formal level of comprehensive planning. We are now working on the District'; last "Master Plan Study" and when the City of Carlsbad - Water Department and the District decide on the ultimate needs of the City service area, we will be ready tn complete the entire District-wide Master Plan. VIII-5 PUMPING , 'There is sufficient hydraulic grade (978 - 935) from the aqueduct, so there is virtually no requirement for pumping within the entire service area. This has obvious advantages in that it eliminates energy costs, capital costs for pump stations, as well as the maintenance problems that are affiliated with any mechanical device. However, there are numerous pressure reducing stations that require maintenance and replacement. VIII-6 NEW CAPACITY Planned Storage - Costa Real 1 . 2. 3. U. 5. 6.

Should the Health Department decide to restrict or eliminate Squires I, this would reduce ultimate storage capacity to 1,135.52 ACFT which is slightly less than the required 1375 ACFT (21 days of average annual storage). It can be noted in the foregoing analysis that Squires I and Squires II are a very integral part of the service area's storage needs. Should the Health Department remove Squires I from active 1. The T.A.P. Reservoir is to be shared 50| City, 50% Costa Real M.W.D. VIII-7 service, this could accelerate the need for acquiring or building additional storage to maintain the 3 week storage capaci ty. A study may be necessary to determine the economic practic- ability of constructing a filter plant downstream of Squires I If the Health Department determines that it is no longer an acceptable filtered water storage reservoir. TRANSMISSION LINES Costa Real has approximately 75 miles of transmission and distribution pipelines, ranging in diameter from 6" to 27". The District is relatively undeveloped/ thus more pipelines will have to be constructed to provide service for ultimate development. Since the District's Capital Improvement program is very generalized, cost extimates were not included. However, it can be estimated that approximately 50 miles of 12" through 18" water mains will be necessary to complete the primary system for the ultimate development of the service area. In order to accurately estimate the magnitude of this particular element, it would be necessary to completely study the area. This would ' include a master water plan for the entire service area, outlining total water demand by service zone as well as the necessary pipelines and storage facilities. VIII-8 For the purpose of this study it will be assumed that an equivalency of approximately 50 miles of 16" waterline will be needed for ultimate development. Based on current prices, a 16" waterline will cost approximately $60./ft. for a total cost of $15.8 million. This would include about $1*50,000. for the proposed Ik1' Elm Street line. In all probability, the construction of these pipelines will be a combination of developer/agency responsibility. As previously mentioned, one of the critical factors in planning a capital funding program is trying to determine specifically what is needed and when, as well as who is going to pay for it. If the proposed storage were to be constructed at today's dollars, this would result in an expenditure of $21,630,000. Obviously, this is not going to happen and it will be necessary to program the construction of pipelines and storage taking into consideration inflation and cash flow. VIII-9 CITY OF CARLSBAD The City of Carlsbad Utilities and Maintenance Dept. has developed a 5 year Capital Improvement and Replacement program. As noted in Appendix A, part of this program includes an allocation of $2,050,000. for it's share of a joint operations facility. In addition, a study completed in 1979 "Master Plan for Public Water System for the Northeast Quadrant Water Service Area", identified storage and pipeline requirements for the City of Carlsbad. This amounts to one half of the cost of the Tri-agencies pipeline storage for $625,000., plus approximately $5if7,000. for additional pi pelines. The foregoing Chapters have identified major facilities that will be necessary for the ultimate development of the community water plan. They are summarized as follows: City of Carlsbad - Faci15 ty Cost Replacement Program (Table 6) $ 823,000 Storage (1/2 of T.A.P. Reservoir) 625,000 New pipelines 5U7,000 Joint use of Operations facility ' 2,050,OOP, TOTAL $1*,01*5,000, 1. Water Utilities Fund VIII-10 Costa Real Municipal Water District Facility Cost Pipeline Replacement Program (Table 7) $ 3,500,000, Storage 21,630,000, New pipeline construction 15,800,000, TOTAL $UO,930,000 The foregoing Table indicates the community will be faced with the funding of approximately $45,000,000. worth of replacement and new facilities. It is also recognized that a portion of these costs will be developer responsibility, however, at this time it is impossible to identify the developer's cost. It should also be recognized the foregoing prices are based upon 1981 dollars. Inflation will take it's obvious toll. VIII-11 CHAPTER IX. FINANCE A critical issue is going to be who pays for these facilities and how. A comprehensive financial management program has to sustain not only the water utilities operation, but it's capital funding needs as well. It is necessary to examine not only water rates/ but all sources of revenues so they may be appropriately integrated into the agency's cash flow. Obviously, the main thrust of any program is to assess an equitable charge to the benefiting user. Determining what this charge will be and the amount of benefit, requires not only a fiscal analysis, but policy guidance as well. Since there is no one charge or system of charges that is the answer to all funding problems, it is necessary to look at as many sources as possible and then select those most appropriate to the situation. POSSIBLE FUNDING PLANS A policy may be established wherein operations, maintenance, and replacement costs be totally funded by the water user. Currently, the agencies depreciate their facilities based upon original installation cost, however, it is recognized IX-1 the funds set aside based upon this method of depreciation would be totally inadequate for future replacement. If this method of funding replacements were to be implemented/ it would be necessary to revaluate and consider the use of replacement cost accounting in the establishment of a depreciation schedule and replacement fund. This would obviously be a radical departure from the current accounting system. All capital improvements, other than maintenance and replacement/ could be funded from a combination of charges/ such as; 1. Developer contribution that is paid at the time of filing a subdivision map. 2. Connection fees (capacity buy-in fee). 3. Annual acreage standby assessment. U. Assessment District Bonds. 5. Revenue sharing/ i.e./ block grants. 6. Revenue Bonds. 7. Municipal lease back/Non Profit Corporation. The above list of possible revenue sources for the funding of the Capital Improvement program offers a means of distributing the burden over as many beneficiaries as possible/ thus increasing the chances for an equitable distribution of this capital burden. The selection of the appropriate mix would require a model study, taking into account the various parameters as the policy making bodies see fit for their IX-2 community. An analysis of this type could be updated on an annual basis to insure that it reflects current community thinking and needs. At the same time, it would offer a means whereby the community could evaluate the effectiveness of their water development program. In an area that is fully developed, it can be argued all revenue should be derived from the user, i.e., through the water rates. This method has been used extensively and proven to be effective. However, in a developing area, the situation is more complex. For the most part, placing the entire burden for system development upon the existing water user could be prohibitive. Further, it would not be equitable as the undeveloped land has value because of the availability of water. In order to overcome this inequity, the Legislature has authorized a combination of charges that can be implemented for this specific situation. It would appear appropriate that in the undeveloped areas of the community, the use of a capacity fee, an annual standby charge, along with an assessment district, may be the most appropriate method of funding Capital Improvements. IX-3 MUNICIPAL IMPROVEMENT ACT OF 1913 WITH 1915 ACT BONDS The Municipal Improvement Act of 1913 differs from the 1911 Act principally in that assessments are made in advance of doing the work. This Act can be used to acquire or install most types of local improvements, including water mains, pipes, conduits, tunnels, hydrants, and other necessary works and appliances for providing water service. The acquistion of water facilities may include plants, lands, and rights-of-way located within or outside the boundary of the municipality. The code also permits the acquistion of use or capacity rights in public facilities, such as water and sewer systems. Bonds issued under the 1915 Act are secured not by separate parcels of property as are 1911 Act Bonds, but by a Trust Fund consisting of payments made by all property owners in the District assessed. This form of financing is becoming more widely accepted as a means of replacing General Obligation Bonds for the development of facilities in undeveloped areas. It can be argued the expansion of the system, in developing areas, should be totally funded by the developer/builder in the form of a connection fee or developer contribution. Developing the community infrastructure, I.e., water and IX-i* sewer systems/ etc., is becoming such a burden that it is now a major cost item in the price of new housing. Policy making bodies have the power to encourage or inhibit development in the application of these charges. REVENUE BONDS The Revenue Bond law of 19U1 empowers any local agency to finance a wide varity of revenue producing facilities through the issuance of Revenue Bonds. The Bonds are secured solely by a lien on the gross revenues of the enterprise for which issued/ and such other funds as may be described in the resolution authorizing their issuance. Should the local agency determine to issue Revenue Bonds/ it's legislative body/ by resolution/ submits a proposition of issuing Bonds to it's voters at an election held for that purpose. This form of financing has been particularly successful for large agencies providing water and sewer service where the revenues derived from connection fees and monthly service charges can be pledged to secure the debt payment. However/ for smaller agencies the revenue may not be sufficient to justify the issuance of this type of Bond. IX-5 MUNICIPAL LEASE BACK - NON PROFIT CORPORATION This form of financing had it's first major start in Los Angeles County in the early 1950's. It was a rather radical departure from conservative and traditional means of Municipal finance. Tax payers and investment bankers opposed the lease purchase agreements for two basic reasons. (1) They felt it could promote unsound ventures which may undermine Municipal credit. (2) Cost the taxpayers excessive Interest when compared to General Obligation Bond charges. In addition, there are some who argue that it bypasses voter wishes, in that this type of financing can be done without a vote of the people. Should an agency decide to pursue this form of financing, it would first establish a nonprofit corporation to build a needed facility. The nonprofit corporation would issue Bonds to raise sufficient funds to construct the facility. The lease or rental payments, payable under the contract, are assigned to the Bond holders as security for the Bond payments. The use of this method of funding may become popular for thosefaci1ities that cannot be funded through the 1913/15 Act assessment, due to the nature of their use. For example; there are certain facilities that cannot be directly related to a particular area of benefit and, as IX-6 such, would not be practical to use the Assessment District proceedings. However, the Municipal Lease Back which, in essence, is almost the same as a Revenue Bond would provide funding for this type of facility. Charges could be levied against the beneficiary of the service in proportion to benefit. STANDBY CHARGES Revenue derived from the ad valorem taxes has traditionally been the accepted method of paying for Bond debt. However, it was soon recognized that this was not necessarily an equitable means of assessing cost to benefit. There are instances where large tracts of land, used for agricultural purposes, may have an extremely low assessed value, but yet demand a tremendous amount of water. On the other hand, there could be very high value single family dwellings, with little or no water demand, paying a disproportionate higher share of the debt burden. In order to reduce this inequity, the State Legislature enacted a law which gave water districts the right to charge a standby assessment or availability charge on all lands within the district. This charge is based solely on a flat rate per acre and has no relationship to the value of the land. The availability charge is a very effective method of obtaining funds for a capital improvement program. IX-7 Since it Is the utility purveyor's responsibility to provide service as needed, it then becomes necessary to develop a system of charges that can be administered equitably for all beneficiaries. Should the current economic condition prevail for any period of time, the development of an adequate funding program will obviously be more difficult. The onetime tried and true assumptions are no longer valid. The economy is too dynamic. Constant updating of any forecast is mandatory. This situation adds further emphasis to the necessity of long-range flexible financing programs.
