The proposed development consists of 122,092 square feet of building space over 8 lots on 13.72 acres of the Bressi Ranch project. The project is located within the Carlsbad Municipal Water District's .550 Water Pressure Zone. This area of the system is supplied by a 550 Zone Pressure Reducing Station. Existing water service lines within the vicinity of the Bressi Ranch Commercial Site include 12-inch 550 Zone water lines in Gateway Road, EI Fuerte Street, Bressi Ranch Way, Finnila Place and Town Garden Road. Purpose of Study A water system analysis dated October 22, 2002 (revised November 5, 2003) was prepared for the Bressi Ranch project which includes the Commercial Site. This study identified the backbone water facilities necessary to serve the overall project, but did not identify how onsite water service would be provided to the commercial area. The purpose of this study is to identify the proposed water system layout necessary to provide domestic and fire protection service to the Commercial Site. I I I I I I I I I I I I I I I I I I I Jeff Williams November 2, 2007 Page 2 Water Demands The two demands used to design the system are domestic demands from the building and fire flow demands. The projected water fixture units for the buildings have not yet been established. As a result, this water study shows the locations of proposed building water services, but the sizes are to be determined at a later date. Domestic water demands were approximated based on the City of Carlsbad's Engineering Standards, Volume 2 for Potable Water Design Guidelines. Per this document, a commercial average day demand factor of 2,300 gpd/10,000 ft2 was utilized. Maximum day demand and peak hour demands were calculated based on the peaking factors of 1.65 and 2.9, respectively, times the average day demand. A summary of building square footage, associated demands, and hydraulic n;l.odel reference (Node #) can be found in Appendix A. A design fire flow rate of 4,000 gpm was used in the fire system analysis, based on the 2003 Carlsbad Municipal Water District Water Master Plan. Fire sprinkler pipe sizing and design are not considered in this water system analysis and will be p.rovided by others. Proposed Domestic Water System Based on finish floor elevations ranging from 402 to 410.5 feet, the maximum onsite static pressure with service from the 550 Zone ranges from 60.4 to 64.1 psi. Proposed water lines to serve the Bressi Ranch Commercial Site shall be 8-inch and 12-inch. The proposed water lines shall connect to existing water lines within the Bressi Ranch project in four locations. Figure 1 provides the recommended water facilities for the project. I I I I I I I I I I I I I I I I I I I Jeff Williams November 2, 2007 Page 3 Computer Model The KYPIPE computer analysis developed by the UJ?iversity of Kentucky was utilized to determine residual pressures throughout the distribution system. This computer model utilizes the Hazen-Williams Equation to determine dynamic losses in the piping system. A Hazen-Williams "C" Factor of 120 was used in our analysis. Although this factor is conservative for PVC piping, we felt it appropriate to allow for pipe aging and other minor losses in the backbone distribution system. To determine the appropriate input hydraulic gradeline for the computer model, we relied on the November 5, 2003 Potable and Reclaimed Water System Analysis for Bressi Ranch. Table 1 summarizes the available hydraulic gradeline' at the intersection of Bressi Ranch Way and El Fuerte Street (Node 502 from the 11103 Study), TABLE 1 AVMLABLEHGLSUMMARY Avera e Da Demand Peak Hour Demand Max Day + 4,000 GPM Fire Flow 546 526 .-I , ~ __ ....J ' --, ~ ",,"", "" " \ J " CONNECT TO • " /EXISTING 12 .....

The November 5, 2003 water study included hydraulic modeling of the water system to ensure that fire flow requirements could be met throughout the system, including a fire flow rate of 4,000 gpm for the industrial areas. For the on site analysis in this study, the 4,000 gpm fire flow was split evenly between two adjacent hydrants. Appendix B provides a hydraulic model of the onsite system to ensure that the fire flow requirements are met with the proposed onsite piping configuration. The results of the hydraulic analysis indicate that the piping has been adequately sized to supply the domestic and fire protection needs of the project. Exhibit A provides the node and pipe diagram that corresponds with the hydraulic model. Thank you for the opportunity to work on your project.
