GEN.ER.AL AHD INTRODUCTORY: The Carlsbad Municipal Water District is bounded on the North by Bueno. Vista Lagoon, Buena Vista Creek, and Marone Canyon; on the East by San li'rancisco Peak, Mount Hinton, Spillway 349, Rancho de los Q,uiotes, and San Marcos Creek; on the South by San Marcos Creel~ and Batiquitos Lagoon, and on the West by the Pacific Ocean. The gross land area of the District is approx- imately 21 1000 acres, and its topography ranges from a coastal strip of marine sedimentary deposits and salt marshes to gently rolling, semi-barren terrain, increasing in elevation to the East and Southeast, with the greatest altitude a summit of 73S feet in the Southeast sector. The soil pattern varies from rather shallow fine loans and sands in the coastal strip to Fallbrook and Vista loams in the elevated regions East of El Camino Real. Q,ualified authorities have rated the Fallbrook and Vista loams as the oost important agricultural soils in the Dis- trict. (l) In addition to the urban area of Carlsbad, the coastal region West of El Camino Real is presently developed to flowers, winter vegtables, and avocados; the inland elevated regions have not fully realized their agricultural potential because of lack of water. The rainfall expectation for the District is low, between Oceanside Is 12 inches and San Diego Is 10 inches annual average, and the entire County has a history of periodically recurring droughts. ( 2) The City of Carlsbad was incorporated in 1952 and is located in the northwestern 2,500 acres of the District. The present population is 671,9(3) for the City of Carlsbad and about 1,200 for the remaining area, an estimated total of S,OOO.

County Water Authority through the Fallbrook-Oceanside Pipeline, The blending of Mission :Basin well water and Colorado River water has reduced the chloride con- ** tent of Mutual 1s supply from about 300 ppm to 120 ppm, II, PRESEl'IT STATUS OF 1iATER SUPPLY: (a) At the present time the principal agency for the supply and distribution of water within the District is the Carls- bad Mutual Water Company, The Company sells water to its shareholders at cost based upon its water right in the Mission :Basin of the San Luis Rey River, The Carlsbad Mutual has fulfilled its responsibilities in the past through wells drilled into the :Basin, and has maintained a daily reserve through s tora;:;e of about seven million gallons in addition to a permanent roservoir at Lake Calavera, The Carlsbad Mutual 1iater Company reports 2775 a,f,/year as the average metered demand for the seven years, 1947-1954. Its records show that the Mutual has been having trouble with salt water intrusion into the Mission Basin supply and is now (4) March 1950 Report on the Mission Basin by Sonderegger "'* Report -Carlsbad Mutual Water Company C C J:1eeting about one-half of its demand with Colorado River water froJ:1 the San Diego County Veter Authority, (b) The Terra.l!iar Water Company is a privately owned p-11blic utility which supplies relatively small ~uantities of water to the central and southwestern areas of the District, It is presently buying about one-half an aero foot of water a day from the Carlsbad Mutual Water Company and obtains its other supplies from wells drill- ed some four to five miles inland, :Between December 1953 and Uovembor 1954 the (6) Terramar Company pumped about 300 acre feet of wats~ from these wells, This compaey has been using a narrow finger-shaped basin imJ:1ediately southwest of the Agua nodionda Lagoon as an irrigation reservoir, This lake impounds possibly lOO a,f, of irrigation storage only; storage tanks hold l,l million gallons of well water for doJ:1ostic use, Tho total production of Terra.mar, domestic and irrigation, is about 450 a,f,/year, (c) The San Luis Rey Watershed, of which the Mission and :Bonsall Basins are the most westerly, California, ( 7) is one of the large natural underground reservoirs in Southern According to Volk(S) tho estimated consumptive use from the two basins, incl'Clding draft by Fallbrook, Oceanside, and Carlsbad, was about 12,505 acre feet per annum in 1946, Of recent yen.rs the usefulness of the Mission Basin has been reduced because of increasing concentrations of chlorides, However, a reasonable time of relief from excessive pumping plus natural re-charge from in- filtration will help to restore the basin as an acceptable local source of dom,- estic and irrigation water, It is expected that the developmant of a full ~uoba of Colorado River water will enable tho basin in timo to recover its value as a local source of well wator, (6) ( 7) (S) From Records of II', D, Cannon, owner Terramar 1'1ater Company, C, S, Alverson1s Report of the Dept. of Water to the Common Council (San Dtego) on the San Luis Rey River (1915).

PBESENT STATUS OF AGRICULTURE IH THE DISTRICT: The Carlsbad District is relatively 'lllldeveloped agriculturally because of insufficient water. An adequate supply of water of suitable quality would 'lllldoubtedly result in a considerable increase in agricultural activity including truck gardening, flowers, citrus, and avocados. If 135 gallons per capita per day dooestic consumption is assumed, the reoainder left for irrigation is 2064 a,f,hrear, .According to the Carlsbad office of the Cruavo Growers Association of Southern California, the estimated acreage at present devoted to avocados amounts to 350, all West of El Camino Real. The same source reports about 50 acres planted to lemons and limes, Flowers and bulbs acco'Ullt for an estimated 450 acres in the District, and truck gardening and row crops take up another 450 acres. The following estimate of agricultural use and water oonsumption emerges froo this data. -4- C ESTIMATE OF PRESEli'T CROP :P1STRIBUTI01T Alm ltATZR COHSUMPTI01T Avocados Citrus Flowers Row Crops Est, Area 350 acres 50 acres 450 acres 450 acres 1300 acres Est, ifater Application 1,5 a,f./acre/year 1,5 a,f,/acre/year 1,7 a.f,/acre/year 1.55a.f./acre/year Totals 525 a. f. /year 75 a,f,/year 765 a,f,/year 699 a.f./year 2064 a. f, /year Field Crops 700 acres: so called dry crops -require no irrigation Pasture 9000 acres: available for agriculture with water Unclassified 6200 acres: land that does not appear to be used for anything at all at present. To be considered productive lend, Subdivision Wasteland 100 acres: current estimate 200 acres: rocky, eroded, etc, Carlsbad City 2500 acres: urban Lagoon & Beach 1000 acres: totally unproductive 21,000 acres (gross) 2064 irrigation ~ domestic 3275 a,f./year To s=narize the present estimate, about 1300 acres are productive, using less quantity and until recently lower quality than theoretical needs, The citrus and avocado development in the district has been definitely retarded by the s1:1all quantity and increasing salinity of the present supply, The production of flowers and row crops will rise as soon as additional water at a reasonable ,:,rice becomes available, Finall7, according to the U,S, Department of Agriculture, Soil Conser- vation Service, based upon past studies and preliminary reports of a detailed study of soil distribution in the Carlsbad-Encinitas region to be completed 1n C 1956, the Carlsbad area is rated ten ta ti vely as follows at present: -5 - C C Unclassified -15% (3,150 acres) Land Suited for Cultivation -41% (8,610 acres) Land Uot Suited for Cultivation -44% (9,240 acres) lly land not suitable for cultivation is meant specifically untillable land in the sense that side slopes are too steep for cultivating row crops, etc, It should be remembered that many of these side slopes will support avocado and citrus groves if suitable water is made available, Land suited for cultivation refers to those tracts which are relatively level and are easily worked and maintained with con- ventional fa1,ning methods and machinery, The unclassified acreage includes in part that which is out of the picture agriculturally such as salt marshes, rocky outcrops, etc,, and in part reflocts the fgct that the present survey is not yet complete, In connection with these estimates it can be said that a study of existing development in the Vista and Rancho Santa Fe areas gives an insight into the 911'icultural potential of the Carlsbad District with an adequate and well distributed water supply, IV, POJ?ULATIOU STUDY A11D PREDICTIOU: Plate Ho, l, based upon official United States Census figures, shows that the Carlsbad District fits into the pattern of growth established by state, county, city, and smaller districts in San Diego County since the turn of the century, The increase of population in Southern California has been rapid since 1920 and particularly so since the end of world war II, It is significant that there is no apparent evidence that the population is levelling off, even after thirt;<rfive years of almost unprecedented growth, It appears to be almost incontrovertible that the Carlsbad Municipal Water Dis- trict, the least developed of all the entities shown in Plate 1, is on the verge of its period of greatest expansion. The actual prediction of population is not something that can be set down gs a certainty. In the case of the CMWD howevor, -6 - C C the basis for analysis becomes more rational if the assumption is made that water will be available, and if the District is considered as a part urban, part agri- cultural entity. Chart 3 shows a suggested division of the District into assessed valuation zones, including an estimate for the relative valuations for each zone for different years, Zone I includes the City of Carlsbad, Zone II including the coastal strip and the :Sncina Steam Station of the Son Diego Gas and Electric Com- pan;i•, is e:;:pected to be developed primaril;• to subdivision and light industry. The area included in Zones I and II is estimated at present to be carrying over 95 percent of the total assessed valuations of the CiJ!l.1D, secured, unsecured and public utility. It is semi-urban now and b;i• the year 2000 with extensive sub- division, varied light industry, and Encina financed to near ultimate capacity, will be almost completely urban, It is estimated that 9000 acres of the District·; will eventually become urban. The acrea,gll included in Zones III and IV is at present the most underdeveloped in the entire District. Good deposits of the highly regarded Fallbrook fine sand;\• loams and other loams of agricultural poten- tial are found here. It is predicted that this area will develop almost exclusivel; to agriculture t<hen ,mter becomes available. An ultimate population forecast for the CMl'/D can now be calculated based upon a breakdown of 9000 acres urban and 11,000 acres to agriculture, the remainder being lost to lagoon and wasteland. Past experience and water sup,,ly statistics ascribe an average of about 10 people to an urban acre, and about l to l l/2 people to an average agricultural acre, This wor!ts out to an ultimate population for the C,:,,rlsbad Municipal ~later District of about 110,000. It is not expected that this populati~n will be recorded until well into the twenty-first century, but with the ultimate fixed in mind it is possible to project the official U, S. Census for Carlsbad as followl: Year Population 1970 28,000 -7- 2000 70,000 2050 110,000 C C The following additional considerations are offered in support of this projection: A logical method of population prediction is based upon a saturation concept tied in with economic, climatological, or other factors of rational bear- ing. Factors affecting population growth are climate and natural beauty of terrain; convenient and diverse recreational facilities; accessibility of public transportation and populated urban centers; availability of homesites; etc. No one questions the attractions of the District as a place in which to live, The recreational facilities include the Pacific Ocean and fine beach strands; plus plans for a developed harbor at Agua Eedionda for small boat owners, The Santa Fe Railroad runs the length of the District from North to South, The cities of San Diego, Carlsbad, and Escondido are all within convenient distance, The coast- al strip from Agua Eedionda to Batiquitos Lagoon is one of the few remaining un- subdivided tracts along the Southern California coast, The potential for sub- division and homesites in this area is great and there is strong evidence that the landowners are thinking in terms of future subdivision, The accessibility of the hills east and southeast of the City of Carlsbad and the sweeping panoramic views from these hills make them very attractive as sites for homesteads. Finally, the Encina steam station now being developed by the San Die,c,;o Gas and Electric Company is designed to meet the future power requirements of the entire North Coastal area, and will add to the financial stability of local governmental units as a result of its large assessed value, All this produces pressure for population increase, but it is felt the.t the full effect of these factors upon population growth will only follow m adequate developed water supply, A good study of population trends in San Diego County is included in the 1952 SE1/AGE REPORT submitted to the County by Caldwell, Hyde, and Rawn, Los Angeles Consultants. Plate II shows population prediction curves for the County, North -s - C C Coastal Area, and Oceanside, drawn fror.1 estimates prepared by Caldwell, Hyde and Rawn who have used the well-known logistic curve r.iethod of projection which, in their analysis, is based upon a saturation concept tied in with ultimate foresee- able water su;pply, Included in the curves is the population forecast developed in this section, The predicted trend of population for the Carlsbad Municipal Water District, developed independently froo a different basic analysis, matches the pattern of curves developed from tho studies of Caldwell, Hyde, and Rawn, Additional opinions in connection with population predictions 1n Cali- fornia can be read in a paper presented before the Hydraulics Division of the .American Society of Civil Engineers in San Diego, by Wllliam L, Berry, Principal Hydraulic Engineer for the California State Division of lfater Resources. This Engineer estimates an ultimate population of 4o,70S,OOO for the State of Cali- fornia, and further estimates that of this ultimate 19,182,000 people are ex- pected to live in a 13,000 square mile coastal strip, beginning just below Santa Barbara and extending 250 miles South to the Mexican Border, at an average in- land depth of about 50 oiles, This would include about 70 percent of San Diego County. -9 - C C v.

Present Analysis: Fron a study of past reports alone it might ap~ear reasonable to apply a duty of 1.5 a,f,/year to the Carlsbnd Municipal Water Dis- trict, This would ar:1ount to 30,000 a.f,/year based upon 20,000 net acres. Fortu- nately it is possible to check this figure by using the latest water production data available for several classes of users. Plate VII, Curve Set B, indicates that a duty of 1,5 a,f,/yoar might perhaps apyly to an urbnn consumer such as the City of San Diego if its development were close to ultir:1ate, Curve Set Con Plate VII provides statistical evidence for a per capita wator production ind.ex that can be applied. to the ci~m if it is kept in nind. that the District is to be regarded. as a cor:1bination urban-agricultural entity, Set C shows a clear grouping between what are pri!ll,_'1rily agricultural districts such as the Fallbrook FUD, and -10 - C C urban areas such as the City of San Diego. As time passes and all the users in- volved near their ultimate development it is expected that the indexes of tho agricultural consumers will shift closer to unity and that tho urban index per capita will shift toward 0,10, A tabulation showing these expected variations appears at the end of this section, It is felt that Carlsbadls present index of o.45 for wa ter consumption per acre served (P::.ate vn, Curve Set B) reflects the District·, s pre$em low stage of water deve:i.opmen';, !I'he ).)Opulation increases dis- cussed in Section I'/' will create additional denand i'or water and the index will rise with the increased demand, lt is expec'ued t.hat .he entire array of curves in Set B will rise as the ul tia'1te developmen'u ia approached and that the CMI/DI s index of ultinate water production per acre served will reach 1.2. C. Conclusions; Reports made in the past indicate an average duty of 1.53 acre feet per acre served, Some of them cover only a few thousand acres and all are gross figures, It is believed that a duty of 1.53 ap~lied to the Carlsbad Municipal Water District is out of lino with the facts as shown in Plate VII. When it is noted that the City of Snn Diego's present index of water production per acre served is only 1.3 it is not possible to justify an index greater than 1.3 for the Carlsbad District evon if allowances are mnde for ultimate devolopmont. It is therefore. recomnonded that 1.2 aero foet per acre be ,:qy,)liod tu tho Carlsbad Municipal \'later District; based upon a net acre~.ge of 20,000 this computes to an ultinate duty of 0,bout 24,000 acre feet por year. -11 - C C TA:SULATION Prodictea:---w'iitor-Prod.

The sum of secured and unsecured valuations cnn be regarded as somewhat high for the water district. For instance the 1954 figures for the school dis- trict (secured and unsecured) amount to $10,375,150 as against a total of $ 9,051,290 reported for the we.tor district in the Sth Annual Report of the 'JIU;..

According to reliable sources the present expenditure on the development, including land and dredging, is about$ 24,000,000 with the ultil!lnte investment expected to pass$ 60,000,000, Tho figure of$ 16,600,000 given for total assessed valuation in 1955 as shown on Chart 4 includes on esti- mate for tho initial valuation of tho Encina Power St;,,tion, in addition to an estimated present valuation for the District of$ 9,300,000. VII. PREDICTED TRElID IlT ASSESSED VALUATIOH: Plate IV is derived from titatistics which appear in tho Sth Annual Report of tho OWA. A study of tho gre.phs indicates than an approach for predicting futures in valuations in Southern California l!lllY be made on a per capita basis. If a logical prediction of population is assuned, tho problem narrows down to the selection of a multiplying factor which will yield a valuation prediction related to population. Statistics of valuations divided by population in the County from 1920 to 1954 provide figures which range from $ 319 per capita for Ocennsido in 1920 to about $ 1000 per capita in 1954. Escondido 1s present ind.ox is about 1230 and tho City of Snn Diogo 1s is about 11250 Tho CMWD, with 1955 osti!l11'.ted vnluntion of$ 9,300,000 and population of 8000, has an index of 1162. lt is recognized that those factors are by no means const~t, and are not always consistent fro1:1 year to yeor. Hovertheless it is believed that they do provide a basis for long-range osti1:1ate that cnn bo regnrded ns reliable. Additional study of Graph :s, l?latc IV shows that the OMIID st,;inds reasonably placed between tho high md the low vn.luo.tions par capita for other entities in ( 9) So.n Diego Union. Jnnunrj' 3, 1955. Construction Report Carlsbad City Building Clerk, -13 - C C Southern California, developed and undeveloped, It is not expoctod that anything will occur in tho foreseeable future to alter the pattern of this grouping radically, Possibly, in the case of tho CMWD, the ratio of valuations to popu- lation will increase sl ightl;r with development, In this report the present index of 1162 is used to 1975 1 and from there on to tho ultimate an index of 1182 is used, It is concluded, therefore, th~,t tho assessed valuation of the region, secured and unsecured, will roach$ 32,600,000 by 1970 with a predicted popula- tion of 28,000 and is expected to reach $ 62,700,000 by t,he year 2000 with a predicted population of 70,000, When the esti.matod assessment for tho Encina Power Plant is added these figures increase substantially, Chart 4 shows the ex- pected distribution of valuations by zones.

XI, TIDJ FBESjillT POSITIOlT OF TH:3 1':ATZR AUTHORITY AS IT AFFECTS Tltll CMWD: Tho 6th Annual Report of tho San Diogo County 1/o.tor Authority states tho.t preliminary studies now being r1c1.do indico.to a necossi ty for two additional linos froo tho -16 - C C Stan Diego Aqueduct, one of which would branch off North of Escondido and extend to the Carlsbad M,\-1,D, via the San Marcos Valley, The Authority has made prelim- inary studies for the approximate water requirements and pipeline location for a San Marcos-Carlsbad Aqueduct, This is included in an over-all master plan, en- compassing the entire County, which is to appear soon in an official CWA report, A San Marcos-Carlsbad extension is being considered by tho Authority1 and might be approved by them in time for construction before 1960. In addition to meeting Carlsbad1s requirements it is expected that this line will be designed to service other districts in the San Marcos Valley and the coastal strip, It is not certain whether the Authority will include permanent storage in connection with first stage planning for the proposed San Marcos-Carlsbad Aqueduct, It is not possible to say yet when the CWA 1s plans for county water supply improvements will reach the construction stage, The problem of immediate water need however is still outstanding, This is of particular interest to Carlsbad because their demand already exceeds the available water supply and it is important that the needs of the District be satisfied as soon as possible, It is important to note that a de- lay of even two or three years in the construction of adequate transmission facilities of the San Diego Aqueduct to the Carlsbad area will result in a loss to the people end the businesses in the Carlsbad district of several million dollars. This loss would result from the further decline of property values due to an in- adequate water supply and a further dela:• in the growth and development of the area, XII. RESERVOIR SITE: In addition to transmission lines it is necessar:r that the Carlsbad M,'J,D, give consideration to terminal storage in order to accol!lllOliate seasonal fluctuations in demand, Seven reservoir sites have been investigated in connection with this study. -17 - C C San Diego Aqueduct, one of which would branch off North of Escondido and extend to the Carlsbad M,1'f,D, via the San Marcos Valley, Tho Authority has made prelim- inary studies for the approximate water requirements and pipeline location for a San Marcos-Carlsbad Aqueduct, This is included in an over-all master plan, en- compassing the entire County, which is to appear soon in an official C1·1A report, A San Marcos-Carlsbad extension is being considered by the Authority1 and might be approved by them in time for construction before 1960, In addition to meeting Carlsbad1s requirements it is expected that this line will be designed to service other districts in the San Marcos Valley and the coastal strip, It is not certain whether the Authority will include permanent storage in connection with first stage planning for the proposed San Marcos-Carlsbad Aqueduct, It is not possible to say yet ,-,hen the CWA 1s plans for county water supply improvements will reach the construction stage, The problem of immediate water need however is still outstanding, This is of particular interest to Carlsbad because their demand already exceeds the available water supply and it is important that the needs of the District be satisfied as soon as possible, It is important to note that a de- lay of even two or three years in the construction of adequate transmission facilities of the San Diego Aqueduct to the Carlsbad area will result in a loss to the people and the businesses in the Carlsbad district of several million dollars.

Hinton 3, Manos Cneyon 4, 11J!J of Spillway 349 5, Son Marcos Creek (Meadowlark) 6. San Elijo Canyon 7, South of San Elijo Caeyon RESERVOIRS ---------- Approximate Capacity 15,000 acre foot 11,000 aero foot 975 aero foot 12,000 acre feet 27,000 aero feet (Crest elev, 4301) 50,000 aero foot 24,200 acre feet Renarks Construction would involve flooding Highway 78, Good storage site for CM\'/D, Not too well loc~.ted to serve entire District economically, Too snall. Too expensive to en- large cnpacity, Crest length excessive. Too 0:&)--, pensive to construct, Ap9ears to be best sito for cnpacity location, and possible mutual financ- ing with other agencies, Remote fron District, Length of transmission lines excessivo. Remote from District. Crest length excessive, too expensive to construct, Of the seven locations investigated, the Mount Hinton nnd Meadowlark Reservoirs appear to be most logical by location, cl'.pncitJ', and volume of cL."'J:l embankment. Tho Mount Hinton sito suffers from the disadvantage of not being ideally located to servo the District economically. In addition to this it appears to be of benefit to the OMl'ID only nnd the ontiro cost of construction and mnintoncnco would be borne by tho District. It is concluded that the Meadow- lark site is best suited for tho initial and ultimate storage needs of tho CMi'ID for the following reasons: 1. Reservoir is so located that it can serve other districts besides tho Cl~'/D and tho cost of naintenanoe and construction crm probabl;r be financed by mutual agreonent, -lS - C C 2. The reservoir is well located with reference to Hill 73s. This is of im- portance with respect to the ultimate development of the District. Pumping from Meadowlark to steel storage tank atop Hill 738 makes regulated gre.vity flow possible from this height to the regions in tho southern half of the CMWD which are e:q:,ected to bring the water demand up close to the ultimate in a bout 35 years. 3. The ca:;,aci ty of the reservoir can be increased rolat ively easily if future demand warrants. 4. The resorvoir is located so that it will be the logical terminus of the Carlsbad-San Marcos Aqueduct as proposed by the County 'Jater Authority studios, Tho cost of this reservoir will of course depend upon the capacity developed. It is estimated that t:·,is reservoir could be dovolopod to a capacity of approximately 16,000 acre feet for a capital cost of approxirnatoly $1,000,000. Considering wind, ex-posed surface and number of days with sun common to San Diego County an evaporative loss of approximately 1,000 acre foot per :;ear should be OXJ.1ected from this reservoir. 1Tith roforonce to terminal storc.;,e, it appears probable that tho County WatEJr Authorit;r will develop the Meadowlark Reservoir by 1970. In tho ovont that tho -~uthori t7 should decide upon a policy of leaving the construct ion of terminal storage to its member agencies, tho Carlsbad Municipal Water District should place itself in tho position of accomplishing the construction of this reservoir either b;r itself or in cooperation with other interested water districts. XIII •• -P20?0SED ''TATLR SYST3l~ -IlITTIAL ,UJD ULTIV:ATZ: This ro,_,ort is concerned with the ane.lysis of a t-1ater transmission, p:r11llBI'7 diiltriouU.on and atorage s79tem for -19 - C C the Clll'lsbad Municipal Hater District. Tho manner of distribution of water to individunl consumors is a separate problem and no attempt is mo.de heroin to de- fine its solution. The eastern boundary of the Carlsbad Municipal tlator District lios approxi- mo.tely 9 miles west of tho San Diogo Aqueduct, It will be necessacy to construct a su:pply main from the Aqueduct to the Carlsbad Arca, This main is referred to in this report as tho Carlsbad-San Marcos Aqueduct, It is proposed that tho Carlsbad- San Marcos Aqueduct be constructed from tho intersection of tho San Diogo Aqueduct with Rincon Avenue, north of Escondido, ond run through tho San Marcos Valley to a 3,000,000 gallon reservoir on Hill 780 east of tho Rancho de los Q,uiotes, From Hill 780 a primary distribution main is proposed to run •.icsterlJ• to tho El Camino Roal, At this point, which is located southe.!',st of Agua Hodionda Lagoon, it will branch into a South line running to the coastt'.l strip, npi)roxi!llll.tely midway between Batiquitos and Agua Hedionda Lagoons, and into a north line which will follow tho Real to a 21000 0000 gallon reservoir on Mount Xolly. From this reservoir it is proposed to construct a 12n lino to tho central business district of Carlsbad via Chestnut Avenue to tho intersection of Pino anl Madison, Also, from Mount Kelly another main will continue up El Cru:iino Roal to servo North CrLrlsbad, Chlll't 4 is a schematic drawing of the proposod systom. It is recomraondod that tho initial construction by tho Clll'lsbad MWD be of capacity ade~uate to provido for tho estimated 19S0 water demand, Tho reasons for this roconnondation aro as follows: 1, Considoring tho anticipated ro~id growth ru1d development of tho Carls- bad M\J'D arcn and tho p0ssibility that tho develop~ent nay even exceed thceo esti- mates, it is considorod ill-advised to construct a system with loss capacity than that needed to satisfy 1980 demands, -20 - C C 2. It is a fact that the present Son Diego Aqueduct is not dosignod for the ultimato flow requirements of Son Diogo County, and studios which are currently undorwaj' with regard to additional capacity indicate that ony future e.quoducts will be located westerly of tho present one. It is, thoreforo, doomed inadvisable for tho Carlsbad Municipal Water District to construct pipolincs for its ultimate ro- quiremont since that portion of tho transmission main lying oastorly of a new aqueduct would bo of li ttlo or no use ta tho Carlsbad Municipal \'later District and further that tho lines in on ultimate system, if laid out at this time, might not be ideally located with reference to future additions to tho San Diego Aqueduct system. 3. Because of tho oxistonco of several factors which at this time are com- pletely indeterminate with reference to tho future source of water for tho Carlsbad Municipal Water District, it appee.rs that a progrrun which would call for a re- analysis of tho needs of tho district after a period of 20 to 25 years provides the most economic solution to the overall problem confronting tho district, Should tochnological advances in tho field of desalting of sea water advance to tho point of making such ,mter availablEl economically then certainly the Carlsbad Municipal Water District wou:..d be obtaining its water from its western boundary rather than its eastern. It is oxpectod that by 1975 or 1980 the multitude of problems con- fronting Southern California with respect to its future water supply, will hnve boon solved and that a final analysis of the problem would be possible at that tioo, The predicted Yater demand of the Carlsbad M\'/D ns shown on Plato VIII indicates that for several years there will bo a surplus capacity available in tho mains proposed herein. It is believed thtit neighboring water agoncios, and partic- ularly the Vistn Irrigation District nnd tho San Marcos County 1:/ntor District, would be interested in leasing such sur:?lus cnpacity as tho C.:,,rlsbnd. M\'l'll !'light -21 - C C a,groo to make nvailablo tooporarily, lly leasing such surplus capc.ci ty the Carlsbad District can accur.iulate additional revenues to assist in tho ar.iortization of tho pipeline cost. Due to the tine required to cooploto a bond election and sale of bonds and tho preparation of engineering plnns for such a project, it is physically i&- possible for any group of agencies or for tho County 1fotor Authority to arrange for tho finllllcing and to prepare engineering plans for tho construction of this line in tine for such construction to bo complete for the irrigation season of 1956. Only if the Carlsbad District oov0s immediately and alono can tho construction of such a lino bo coopletod in tine to supply tho Carlsbad MUD with an adequate and continuing supply of Colorado River water by July l, 1956, By owning and controlling tho lino, tho Co.rlsbad District will bo able to accrue rovonuo fron tho lensing of the initial surplus capacity thus assisting in tho amortization of tho capital cost, If a similar lino were constructed by any other entity or combination of entities tho relatively high assossod val.uation of tho Carlsbnd District and its anticipated honvy water dornnnds would result in tho Carlsbad District bearing the burden of tho cost of any such lino constructed without tho benefit of additional returns from leased surplus capacity. Tho entire area of the Carlsbad Municipal ~later District has a very pronising future and tho early and full dovolopoont of this region will accrue to tho benofi t of all present residents. Tho only reason that this aroa is not now highly developed is that the available water supply has boon insufficient to noct tho needs of the area. The illll?lediate construction of tho facilities proposed in this report would enable the district to enjoy tho benefits of a rapid and secure dovolopnont at an early date. In the course of tho study and investigation loading to this report -22-- C C all other possible sources of water supply for the Carlsbad Municipal Water Dis- trict wore reviewed and analysed. Tho present Mission Basin source from which tho Carlsbad Mutual Wat or Conpany obtains most of its prosont supply is d01Jleted to the point of critically affecting its quality end tho reliability of this source is soriouely in question. The only adequate source of water available to the Carlsbad Municipnl Water District at tho present Md in tho forGsoeable future is tho prosont San Diogo Aqueduct. The system proposed in this report is tho most efficient and economic means of supplying tho water requirements of the district from this source. XIV. ESTIMATED COST: The estimated cost of the water systOJl proposed in this re- port is given in Table I. This cost estimato covers the C,:,,rlsbad-San Marcos Aqueduct as well as the primary distribution and regulating storage fncilities included in the system. This esti=to does not include funds for such items as Carlsbadls participation in the construction cost of terminal storage or for the aquisition of existing facilities in the event tho owners of such fncilities dosiro to trnnsfor ownership to tho Carlsbad Municipal Water District. It is tho opinion of the writer, however, that an ndditional sum dhould be provided in a water bond authorization to provide for the acccmplishnont of these i tor.is if necessary. XV. MZTHOD OF FIN.ANCING1 Since the srstem proposed in this report has been de- signed to provide n general bonefi t to oJ.l properties located within tho District, it is recoonendod that tho system be financed by tho issuance of gonornl obligation bonds. Since it is expected that development will occur at a rnpid rate upon the completion of the proposed system, and that such dovelopmont will create new tax,. able wealth, it is rocoooondod toot the DOortization of the proposed genornl -23 - C C obligation bond issue provide for the paynent of interest only for tho first 3 or 4 years and then provide for the ru:iortization of principal in increasing ru:iounts with tho passa.go of timo. This typo of anortization schodulo would insure the proper distribution of the total cost of tho system, The bonds should bo noortizod fron revenues available to tho district from tho t110 principnl s011rcos of trutos and revenue froo water sales, Again this provides an e quitnble distribution al tho burden, It is interesting to note that assuoing D,n interest rate of 35& and a forty year sinking fund nnortization of the issue, a tax rate of fifty cents per $100 of assessed valuation would completely cBortizo principnl and interest if not a single drop of water were sold through the systoo• This oerui.s that tho taxes paid by a property assessed at $2,000 would bo $10.00 per yoo:r while n property assessed at $10,000 would be $50.00 per year, Inoono to tho district from tho sale of water would reduce tho Mounts roquirvd to be raised by taxation. Consequently tho aoounts given above o:ro onximums based on tho assur.Iption of zero water sales, XVI, CONCLUSIOlT: Tho Ct,rlsbad Municipal \'Tator Di strict is nn area with a con- sidorablo potential growth and development, Tho water systoo proposed in this report will nnko possible the prodictod developoont of this area at an early date, An adequate and continuing supply of Colorado Rivor wntor will not only enhnnco tho prosperity of tho area as a result of now growth nnd dovolopmont but it will also stabilize and enhance the valuo of existing dovolopod proportios, Tho Cnrlsbad area can no longer depend 'll'ji>cn tho deteriorating supplies of tho Mission Basin but it must r1ove ahoad to secure its rightful she.re of tho waters of tho Colorado River which are now delivered to San Diogo County thr011gh the San Diego -24 - C Aqueduct. The water systen proposed in the report will accor.iplish this objective with the gren·test ovornll oconomy for the District, C -25 - Respectfully submitted, BOYLE ENGINEERING C APl'Eli!DIX -------- C C .A?FEN.DIX C PLATES: I OFFICIAL U.
