March 23, 2007 DEXTER S. WILSON, P.E. ANDREW M. OVEN, P.E. STEPHEN M. NIELSEN, P.E. DIANE H. SHAUGHNESSY, P.E. 852-001 Tramwell Crow Residential 949 South Coast Drive, Suite 400 Costa Mesa, CA 92626 Attention: Brad Perozzi, Managing Director Subject: Water System Analysis for Poinsettia Commons This letter summarizes our analysis and recommendations for providing potable and recycled water service to the Poinsettia Commons development. The proposed development consists of thirteen buildings comprised of commercial and multifamily residential units. The project is located at the intersection of Avenida Encinas and Embarcadero Lane. The project is located within the Carlsbad Municipal Water District's 318 Water Pressure Zone for potable water service and 385 Zone for recycled water service. Existing potable water service lines within the vicinity of the project include a 12-inch water line in Avenida Encinas and an 8-inch water line in Embarcadero Lane. We recommend that water service connections be made to the existing 318 Zone water pipeline in Embarcadero Lane to serve the project. Based on pad elevations ranging from 56 to 58 feet, maximum static pressures for the project will range from 112 to 113 psi. Water Demands The two demands used to design the system are domestic demands from the buildings and fire flow demands. Table 1 summarizes the projected fixture units for the project based on information provided by the building architect. Using this information and 2234 FARADAY AVENUE • CARLSBAD, CA 92OO8 • (760)438-4422 • FAX (76O) 438-O173 Brad Perozzi March 23, 2007 extrapolating Chart A-2 from the Uniform Plumbing Code, the total project fixture unit count of 2,139 was determined to have an estimated peak water demand of 340 gpm. Appendix A provides a detailed fixture unit count breakdown for the building plan and provides Chart A-2 from the Uniform Plumbing Code.

This table was used to size recommended building service laterals.

Fire sprinkler pipe sizing and design are not considered in this water system analysis and will be provided by others. DEXTER WILSON ENGINEERING, INC.PAGE 3 Brad Perozzi March 23, 2007 Proposed Domestic Water System Based on pad elevations ranging from 56 to 58 feet, the maximum static pressure within the 318 Zone will range from 112 to 113 psi. Domestic water service connections for each of the proposed buildings will be made to the existing 8-inch water line in Embarcadero Lane. Each of the connection points will have a cluster of water master meters and associated reduced pressure principle backflow preventers. The sizing and quantity of water meters in a cluster is not considered in this water analysis and will be determined by others. Table 3 provides the recommended water connection lateral sizes for each building. Figure 1 displays the existing and recommended water system layout for the project.

DEXTER WILSON ENGINEERING, INC.PAGE 4 Brad Perozzi March 23, 2007 Model Development. Analysis using the KYPIPE computer software developed by the University of Kentucky determined residual pressures throughout the fire protection system. This computer software utilizes the Hazen-Williams equation for determining headless in pipes. The Hazen-Williams "C" value used for all pipe sizes in our analysis is 120. The fire protection system was modeled with an estimated hydraulic grade line of 288 feet at the existing 12-inch water main in Avenida Encinas. The fire protection system has been designed to provide a minimum residual pressure greater than 20 psi under a fire flow scenario at all locations within the proposed project development. For the project, a fire flowrate of 3,000 gpm was modeled at nodes 28 and 40. A fire flowrate of 4,000 gpm was also modeled at nodes 8 and 28. The results of the computer analysis indicate that adequate water pressures are provided to the Poinsettia Commons project. Furthermore, fire flow requirements are being met with greater than 20 psi residual pressure at all locations within the project. Appendix B provides the computer modeling output and Exhibit A provides the corresponding node and pipe diagram. Recycled Water There is some potential for the use of recycled water on the site to irrigate the common landscaped areas within the project. This is proposed to be accomplished by making a single connection to the existing 12-inch recycled water line in Avenida Encinas. Figure 1 provides the approximate location of the existing recycled water line and proposed service connection. The 12-inch recycled water line is part of the City's 385 Zone recycled water system. With service from this zone, maximum static pressures on the project are expected to range from 142 to 143 psi. DEXTER WILSON ENGINEERING, INC.

The recommended potable and recycled water facilities for the Poinsettia Commons project are shown on Figure 1. 2. We recommend that building water service lateral sizes of P/2 inches to 21A inches be used to connect to the existing 8-inch water transmission line in Embarcadero Lane. 3. The location and sizing of the water meters and backflow preventers are not considered in this water analysis and will be determined by others. 4. All fire hydrants on the project will be connected to the existing 8-inch water line in Embarcadero Lane. 5. Individual pressure regulators should be installed on all potable water services to maintain maximum water service pressures to the buildings at 80 psi. 6. Recycled water can be provided to the project by connecting to the existing 12- inch recycled water line in Avenida Encinas. Thank you for the opportunity to work on your project. If you have any questions or require additional information, please let us know. Dexter Wilson Engineering, Inc. Stephen M. Nielsen SMN:sbr DEXTER WILSON ENGINEERING. INC.
