It is not a representation, express or implied, that Olivenhain Municipal Water District will furnish water at a future date. Applications for service are governed by separate District rules and regulations, and are the subject of separate and distinct proceedings, apart from hydraulic analysis. All water supplied by the District is imported from the Metropolitan Water District of Southern California via the San Diego County Water Authority. In the event that a water shortage or a threatened water shortage exists, the District reserves the right to restrict or terminate future water service to customers of the District. The District has adopted a water conservation ordinance which is available to all applicants upon request. In order to provide for the efficient utilization of limited water resources, the conversion of irrigation water demands from the potable system to a future reclaimed water system shall be evaluated for all projects and determination of feasibility shall be made by the District, in its sole discretion. A previous analysis titled "Water System Analysis for La Costa Glen Development" was performed for the combined North and South development areas in March 1999. However, the proposed water system piping configuration and dwelling units for the North portion significantly differs from the 1999 study, and thus requires a re- analysis of the project. The purpose of this re-analysis is to determine if the proposed water system facilities are sufficient to serve the La Costa Glen North development, located along the west side of El Camino Real, south of La Costa A venue as shown on Plate I. The proposed water facilities analyzed in this study are shown on Plate 2. These water facilities were analyzed during peak hour and maximum day plus fire flow conditions using the District's 2000 Master Plan's hydraulic computer model (H20NET®). BOl,ILE I La Costa Glen North Development Water System Analysis Source of Water Information describing the development was obtained from a map, dated September 11, 2003, provided by O'Day Consultants depicting the proposed units and water facilities for the project. The project, as analyzed, consist of the following development: Attached Units (Duplexes): Multi-family Units: Commercial Lot: Approx. 52 Single-Family Units Approx. 308 Multi-Family Units Approx. 0.77 acres The La Costa Glen North Development lies within OMWD Pressure Zone No. 2, which has an operational HGL of 409 feet. It is served via several pressure reducing stations and the 1.0 MG Wiegand and 3.0 MG Wanket reservoirs. Water supply to this zone is provided from Pressure Zones 1, 4, and 5. Zone 1 feeds the Wiegand Reservoir, Zone 4 supplies the Wank.et Reservoir and Zone 5 provides water to the Rancho Santa Fe South PRS. Water Demands and Design Criteria Estimated average annual water demands used in this analysis for the proposed development are based on water demand factors utilized by the Olivenhain Water District Water Master Plan dated January 2000. 1. 561 gallons/day/single family dwelling unit (0.389 gpm/dwelling unit) for all single-family residences on lots having less than 0.5 acres of net developable area. 2. 455 gallons/day/multifamily dwelling unit (0.316 gpm/dwelling unit) for all multifamily units. 3. 2,525 gal/day/acre (1.753 gpm/acre) for commercial areas Based on these demand factors, the total average annual day demand for the North project is estimated to be 119 gpm. If anticipated demands differ from those assumed in this report, the District shall be 2 BO~LE La Costa Glen North Development Water System Analysis Results and Conclusions notified immediately and re-evaluation and/or re-analysis of the proposed water system will be made. The system was analyzed for peak hour and maximum day plus fire flow demand conditions. The minimum desirable pressure during a peak hour demand condition is 60 psi. During a maximum day plus fire flow demand condition, the minimum required pressure is 20 psi in the vicinity of the fire. The desirable static pressure range is 60 to 100 psi. Operating pressures during a fire flow demand condition were evaluated based on a fire flow demand of 4,000 gpm as defined by the Carlsbad Fire Department. This fire flow assumes that buildings will be fully sprinklered. If the Carlsbad Fire Department determines that an increased fire flow is required or in the event that the building sprinkler system differs, the District must be notified immediately and a re-analysis will be required. _Irrigation demands, including parks and open spaces, are assumed to be provided with recycled water and therefore a discussion on the source of recycled water and how it is delivered to this project is not included as part of this report. Based on the results of the analyses, it has been determined that with the installation of the water facilities shown on Plate 2, this development can be served during peak hour demand conditions with a _minimum residual pressure greater than 60 psi and during a maximum day plus fire flow demand conditions with a minimum residual pressure greater than 20 psi in the vicinity of the fire. Fire flows for this project requires the upsizing of an existing 8-inch water main to a 10-inch main as shown on plate 2. 3 BO',ILE La Costa Glen North Development Water System Analysis La Costa Glen North Development Pressure Summary Maximum hydraulic gradient elevation based on PRS by-pass valve: Lot elevation range: Maximum static pressure range based on PRS by-pass valve: Minimum Residual Pressure: Max day demand plus fire flow: Peak hour demand: Assessment District AD 96-1: 437 feet 59-102 feet 145-164 psi Greater than 20 psi Approx. 129 psi This development is subject to the terms and conditions of Ordinance No. 280 and successor ordinances of the Board of Directors of the Olivenhain Municipal Water District establishing methods and procedures for the collection of impact charges on properties made necessary by the increase of density at the time of the final subdivision map approval, a change in zoning, or other increase· in water demands in excess of those assessed in Assessment District 96-1. The estimated 432 EDUs for the entire La Costa Glen project (North and South) were presented in the 1999 report. Because of the revised development density in the North area, these EDU's must be revised.

The minimum acceptable thickness of ductile iron pipe shall be Class 52. Refer to Standard Specifications for design requirements of DI and CML&C Steel Pipe. 2. PVC pipe shall be designed in accordance with A WW A C-900, subject to modifications by the District's Representative and the Standard Specifications. 3. Plain end pipe and high deflection couplings shall be used for all curved alignments. The maximum total deflection per coupling is 4 °. 4. Pipe lengths shorter than 9 feet will not be allowed unless authorized by District's Representative. Bell end pipe may be used for straight alignments only. 5. Appropriate consideration should be given to the selection of the centerline radius for curved streets in which waterlines are to be installed. 6. The minimum acceptable radius of curvature for ductile iron or steel pipe shall be based on 80% of maximum deflection recommended by manufacturer for each specific diameter and range of standard pipe lengths and subject to the approval of District's Representative. 7. Water mains shall be located IO feet from center line where ever possible, the minimum acceptable distance between water mains and the back of curb shall be 5 feet. 8. Except for single or duplex family dwelling unit, a water demand summary (fixture units or G.P.M.) for meter sizing shall be submitted during plan check for any facility requiring water for sprinkler systems, pasture/orchard irrigation and commercial or dwelling complexes. 9. For residential or commercial buildings requiring fire sprinkler systems, peak hour demand pressures at the water main shall be used as the basis for design. Oversized street services and meters should be considered relative to the flow/pressure available and that required to operate an individual sprinkler system. I 0. Potable water lines are to be positioned on the south and east sides of streets, and reclaimed water lines on the north and west side of the street where possible. 11. Any project that is located in an area where the District serves, or plans to serve, recycled water shall consider the use of recycled water for non-domestic usage. Projects having irrigation demands which may be met by the use of recycled water will include a dual water pipeline system on-site. Off-site pipeline(s) associated with the master planned distribution system may be required at proposed road improvements and/or existing frontage roads. The dual system(s) will be temporarily connected with the potable water system if the recycled water source is not available Location: H:\001\OMWD Specifications\Standard Notes\Water Design items.doc at the time of construction. All irrigation meters will be served from the future recycled water system. 7. Plans shall include the "Legend Symbols Required for Subdivision Improvement Plans'~ located in this section of the Standard Specifications. 8. The minimum acceptable grade for water mains is 0.5% 9. All existing facilities which may affect final design, i.e., line crossings, line paralleling, or proposed connections shall be field verified. Plans shall show any facilities that are within IO ft of proposed pipelines. Location: H:\001 \OMWD Specifications\Standard Notes\Water Design items.doc I Olivenhain Municipal Water District Guidelines for Placement of Valves on Waterlines Effectively immediately {6/18/03), the District has adopted a new approach to locating waterline valves near tees for distribution system piping in subdivisions. Valve shall be attached directly to the tee (rather than offset some distance from the tee). Presented below are valve and tee configurations that shall be used for such projects. If the need arises for a configuration that does not match any of those shown below, the designer may submit a proposed configuration for review.
