DEXTER S. WILSON, RE. - . KEVIN E. SCHMIDT. RE. ANDREW M. OVEN, RE. I i August 15, 1989 509-005 Hunsaker & Associates 10179 Huennekens Street, Suite 200 San Diego,. CA 92121 Attention: Greg Gallagher, Project Manager Subject: Water Distribution System Analysis for Valle Calavera Village T Introduction This letter-report provides a water distribution system analysis for Village T of the Valle Calavera project located in the northern portion of the City. of Carlsbad. This report determines the required water line sizes throughout Village T, and discusses other required offsite water system improvements, necessary to provide water service to the Valle Calavera Village T development. - Valle Calavera Village T is a 137-acre project ,in north Carlsbad bounded by the City of Oceanside on the north and College Boulevard I on the west. Village T will consist of 343 single family detached residential dwelling units, and a 20-acre junior high school. I .Valle Calavera Village T is within the Carlsbad Municipal Water District service area. The project will obtain water service by constructing offsite water improvements in order to bring the I necessary water systems onsite. The water system improvements will be completed concurrent with required street improvements for the project. Water System Design Criteria . . I The basic design criteria utilized in sizing the water distribution system piping for Valle Calavera Village T includes a minimum residual pressure of 40 psi under peak hour flow conditions, and I .a residual of at least 20 psi under maximum day plus fire flow conditions. I I 2185 FARADAY AVENUE. SUITE 140 • CARLSBAD, CALIFORNIA 92008 • (619) 438-4422 The peaking factors used in analyzing various demand scenarios were 2.0 for average day to maximum day demands, and 4.0 for average day to peak hour demands. V V V A Hardy-Cross type of computer analysis was used to determine residual pressures throughout the development project. This computer model utilizes the Hazen-Williams equation for determining headloss in pipes. The Hazen-Williams 'C' value used for all pipes is 120. I I I I I Fire Flows The. fire flow requirements for the Valle Calavera Village T development are based on planned land uses from the tentative map. A fire flow of 1,750 gpxn was used for single family detached residential dwelling units in order to size the water distribution system for the project. Based on a discussion with the City of Carlsbad Fire Department, a conservative fire flow of 4,000 gpm was used for the junior high school site. . The exact fire flow requirement can only be determined after building plans for the school are submitted to the Fire Department; Water Service. Zones The Valle Calavera Village T projeèt incorporates elevations ranging from 242 feet to 327 feet. This range of elevations falls within the middle zone of the Carlsbad Municipal Water District. The middle zone, also referred to as the low pressure system (only to distinguish it from the high pressure system or the upper zone),, is characterized by a source hydraulic grade line of 490 feet, enabling it to adequately serve the Valle Calavera Village T project. V V V V The middle zone in the vicinity of the Valle Calavera development is served from the six million gallon Tr-Agency Pipeline Terminal Reservoir. This reservoir is located within Valle Calavera Village Q and is filled from the upper zone system extending from the Tr- Agency Pipeline. . Valle Calavera Village T will be connectedtothe middle zone (low pressure) piping which will be installed from the TAP Reservoir to Tamarack Avenue and in College Boulevard as part of the improvements for Valle Calavera Village Q. All of Valle Calàvera Village T will be served from the middle zone (low pressure) water system. . V Projected Water Demand The expected water demand for Valle Calavera Village T was estimated using dwelling unit densities derived from the tentative tract map, and a water demand curve in the February 1985, Costa I I I I I I I I I I I I I I I Real Municipal Water District Master Plan. The dwelling unit density for Valle Calavera Village T was calculated to be 343 I .dwelling units over 116.5 acres equals 2.94 dwelling units per acre. From Plate I of the February 1985, Master Plan, the average demand per dwelling unit is 675 gallons per dwelling unit per day. I The water demand for the junior high school site was estimated using .a factor of 2,500 gallons per day per acre. Total average water use for the Valle Calavera Village T project I is 196 gpm (0.44 cfs, 0.28 mgd). Maximum day demands are estimated to be 392 gpm (0.88 cfs, 0.56 mgd), and peak hour demands are estimated to be 784 gpm (1.76 cfs, 1.12 mgd). Water System Analysis . . . I Appendix A contains the computer runs performed for Vallé Calavera Village T. Only computer modeling in the middle zone was necessary for this I project. Exhibit .A presents a node and pipe diagram for the upper zone computer model and shows the recommended water line sizes for the middle zone (low pressure) water system. I . The water system analysis was based on extending the existing middle zone water system from College Boulevard to provide service to Valle Calavera Village T. Information about existing water I .facilities was obtained from the Carlsbad Municipal Water District engineering department.- As mentioned previously, several "existing" water lines are part of the improvements being completed for Valle Calavera Village Q. I The onsite water system analysis as presented ,in Appendix A consists of several maximum day plus fire flow runs, a peak hour I run, and an average day run. The primary water loop within Valle Calavera Village T is sized as a 12-inch pipeline in. order to minimize headloss in the system. This is considered essential I .because of the several high spots within the development project and the potential high fire flow requirement for the junior high school site. . . I The hydraulic grade line used for the water system analyses was based on an empty TAP Reservoir. A fixed hydraulic grade line of 446 feet was used for all computer runs. I Fire flow to the junior high schOol site was modeled by incorporating a looped water system, within the school site. This was done to ensure that adequate I fire. f low at a residual pressure greater than 20 psi could be obtained at the school site. Because building plans have not yet been completed for the school site, we have no, knowledge of the layout of the water lines within the I . school site. The water lines and sizes shown in Exhibit A are schematic only. . When the building plans for the school , are finalized, and a specific fire flow requirement is established, I L _J additional water system calculations should be done to appropriately size the water mains serving the fire hydrants on the school site. As part of the Carlsbad Municipal Water District master planned water system, Valle Calavera Village T is required to extend a 10- inch water main to its easterly boundary. This middle zone water main will eventually be extended further east by other property owners, and be connected to the proposed middle zone water system within the Carlsbad Highlands development. The 10-inch extension. for Valle Calavera Village T is shown on Exhibit A. It is planned to parallel the gravity sewer easement which is also being-'extended to the . southeastern boundary of the Valle Calavera Village T project. Conclusions The following is a summary of our conclusions and recommendations from this study: . . The water line sizes for the middle zone (low pressure) water system for the Valle Calavera Village T project are shown in Exhibit A. Proposed water line sizes are based. on, our hydraulic analysis of the water system needed to- serve Valle: Calavera Village T. The analysis was performed using the TAP Reservoir as a source and assuming minimum hydraulic grade line of 446 feet.. The water line sizes within the junior high school site are based on a potential fire flow requirement of 4,000 gpm. When a school building layout and the required fire flow are firmly established, a review should be made of the necessary water main sizing within the school site. Individual pressure regulating valves must be installed at all homes on lots at or below pad elevation 306 feet, based on a maximum available hydraulic grade line of 490 feet.
