January 20, 2003 726-001 Ladwig Design Group 703 Palomar Airport Road, Suite 300 Carlsbad, CA 92009 Attention: Bob Ladwig, President Subject: Water System Analysis for the Cantarini and Holly Springs Projects in the City of Carlsbad Introduction This report provides a water system analysis for the Cantarini and Holly Springs projects. This report was originally prepared on September 20, 2002 and was submitted to the City of Carlsbad for review. Comments on the report were received from two sources. First was a letter from Pountney Consulting Group, Inc. dated November 4, 2002, and second was a memorandum from the City of Carlsbad Engineering Design Division dated November 12, 2002. A copy of this correspondence is included in Appendix E. Also included in Appendix E are responses to the comments summarizing how they were addressed in the revised water study for the Cantarini and Holly Springs projects. 703 PALOMAR AIRPORT ROAD, SUITE 300 • CARLSBAD, CA 92009 0 (760) 4384422 • FAX (760) 4380173 Bob Ladwig January 20, 2003 The Cantarini and Holly Springs projects are located east of El Camino Real along the east side of the extension of College Boulevard. These two projects are adjacent to each other with Holly Springs positioned on the north property boundary of the Cantarini project. Exhibit A at the back of this report presents the layout of these two projects. Access to the Cantarini project will be from the extension of College Boulevard; the Holly Springs project can only be accessed through the Cantarini project. The Cantarini project proposes a total of 105 single family detached residential homes and 80 multi-family units. The Holly Springs project proposes 39 single family detached residential homes plus four future single family home lots. Finish grade for building pads within these two projects range in elevation from a low of 120 feet to the highest building pad which is 380 feet in elevation. Purpose of Study The purpose of this study is to provide a water system analysis based upon the lot layout and street layout of the proposed Cantarini and Holly Springs projects. This report provides a recommended water distribution system to serve the proposed residential development. It also addresses issues such as reservoir storage requirements and relocation of transmission piping within the projects. Water System Design Criteria The design criteria used in sizing the water distribution system piping for the Cantarini and Holly Springs projects is consistent with the City of Carlsbad Water Planning Criteria. This criteria includes a minimum desirable static pressure of 60 psi, and a maximum desirable static pressure of 120 psi. DEXTER WILSON ENGINEERING, INC. PAGE 2 Bob Ladwig January 20, 2003 Under Peak Hour Demand conditions, minimum residual pressure at any location must not be less than 40 psi. Under a Maximum Day Demand with Fire Flow, a minimum residual pressure of 20 psi must be maintained at the location of the fire demand. Peaking factors used in analyzing various demand scenarios were.5Nfor average day to maximum day demands, and 4.0 for average day to peak hour demands. Proected Water Demand The expected water demand for tie Cantarini and Holly Springs projects was estimated using a demand factor ogallons per person per day (200 gpcd) per the City of Carlsbad Water Planning Criteria. The population density per dwelling unit for these projects is presented in the Zone 15 Buildout Population Projections to be 62.3178people per dwelling unit (ref. Zone 15 Facilities Plan). This results in an average daily demand factor ofth ë'gpd per dwelling unit. Table 1 below presents a summary of the projected water demand for the subject projects.

PAGE 3 Bob Ladwig January 20, 2003 Fire Flow Requirements The fire flow requirements for the Cantarini and Holly Springs projects are based upon the planned uses within the projects. Single family detached residential development requires a fire flowj,500 gprn: For the multi-family residential portion of the Cantarini project, the fire flow requirement assumed for sizing the water distribution system was 3,000 gpm. Actual fire flow requirements have not been established by the City of Carlsbad Fire Prevention Department for the Cantarini and Holly Springs projects as of the date of this report. Water System Comnuter Model The University of Kentucky KYPIPE program was used to .computer model the proposed water system for the Cantarini and Holly Springs projects. This computer program utilizes the Hazen-Williams equation for determining head-loss in pipes; the Hazen-Williams "C" value used for all pipes is 120. The hydraulic modeling in this report is separated by water service zones. A separate computer model was prepared for th 5 Zone and the 490 Zñe. For the 375 Zone, the available hydraulic grade line is based on setting the downstream hydraulic grade line at the existing pressure reducing station within The Terraces project to 375 feet. At the other end of the modeled 375 Zone system, the hydraulic grade line was conservatively assumed to be/365 feefBecause of the large size of the 375 Zone service system, only a portion of this system was included in the modeling effort for these two development project'\ For the 490 Zone system, the available hydraulic grade line was set to be'490 feet at the intersection of College Boulevard and El Camino Real. This point is on the existing 36-inch 490 Zone transmission main which connects to the existing. 27-inch Maerkle Reservoir Transmission Line originating from Maerkle Reservoir. DEXTER WILSON ENGINEERING, INC. PAGE 4 Bob Ladwig January 20, 2003 Existing Water System The existing water system to which the Cantarini and Holly Springs projects will connect is located at the two extremes of the proposed projects. At the south side of the projects, connections to existing water facilities will be made iiiCollegé Boulevard east of El Camino Real. At this location, College Boulevard contains two potable water lines; a36-inch 490 Zone pipeline, and a 12-inch 375 Zone pipeline.. At the north end of the Cantarini and Holly Springs projects, connections will be made to potable water lines at the intersection Of College Boulevard and Cannon Road. At this location there will be both a 490 Zone pipeline and a 375 Zone pipeline in the near future. South Side Connections. The. 36-inch 490 Zone pipeline in College Boulevard east of El Camino Real is connected to the .36-inch 490 Zoiie transmission main in El Camino Real. The new 36-inch water line was constructed in College Boulevard in order that it can eventually be extended east across the Agua Hedionda Creek and south to the Maerklé Reservoir. This 36-inch pipeline is master planned to parallel the current 27-inch 490 Zone transmission pipeline which extends from Maerkle Reservoir to El Camino Real. This capital facility is part of the Carlsbad MWD Master Plan and will be funded by the Carlsbad Municipal Water District. ve The 12-inch 375 Zone pipeline is connected to the water distribution system within The Terraces residential project. The source of this water is a pressure reducing station within The Terraces project which breaks 490 Zone pressure to the 375 Zone. In addition, once The Terraces project is completed, there will be a 375 Zone connection north to the existing 375 Zone system in Jackspar Drive on the west side of El Camino Real. DEXTER WILSON ENGINEERING, INC. PAGE 5 Bob Ladwig January 20, 2003 The City of Carlsbad Water Master Plan Update (draft report dated January 2003) shows a master planned 12-inch 375 Zone water line improvement within College Boulevard from The Terraces project north to the Cannon Road intersection. From this intersection, the 12-inch 375 Zone water line improvement continues west in Cannon Road and connects to existing 375 Zone facilities in El Camino Real. The portion of piping within Cannon Road is currentlyunder design by Dan Boyle Engineering for the City of Carlsbad. North Side Connections. On the north side of the Cantarini and Holly Springs projects there are master planned water facilities located at the intersection of Cannon Road and College Boulevard. These include the 12-inch 375 Zone water line discussed in the previous paragraph. Also, the City of Carlsbad is currently in design of a 16- inch 490 Zone pipeline extending north in College Boulevard from the Cannon Road intersection. This line will connect to facilities in the Calavera Hills area being constructed by development projects that tie to the TAP servoir. The 16-inch 490 Zone pipeline in College Boulevard will be stubbed to the south Of the Cannon Road intersection and will be available for connection to the' 490 Zone facilities which the Cantarini and Holly Springs projects will be building along with the construction of College Boulevard which abuts these projects. Figure 1 presents a map of the water system in the vicinity of the Cantarini and Holly Springs projects and shows which facilities are existing, which facilities will be constructed by the proposed development projects, and which facilities will be constructed by future development adjacent to the Cantarini and Holly Springs projects. Water System Analysis and Results The discussion of the water system analysis for the Cantarini and Holly Springs projects will be separated into the two water service zones within these two projects.

The computer analyses performed for the 490 Zone system are presented in Appendix D of this report. The results show that minimum residual pressures throughout the two projects are satisfied under all flow scenarios based upon the recommended layout of the water system as shown in Exhibit A at the back of this report. Approximately half of the Cantarini property and all of the Holly Springs project are intended to be served from the 490 Zone with different sized pipelines creating a loop through the two projects. The source of 490 Zone water will be the connection to the proposed 36-inch 490 Zone water transmission main in College Boulevard extending from El Camino Real to the south and east. This 36-inch transmission main is proposed to be extended north in College Boulevard to "A" Street within the Cantarini project. Here, the 36-inch transmission main will be routed to the east end of the proposed subdivision. Future projects to the east (Mandana and Kato) will be responsible for providing an alignment for this 36-inch transmission main up to Maerkle Reservoir. This new 36-inch 490 Zone transmission main is intended to parallel the existing 27-inch transmission main between Maerkle Reservoir and El Camino Real. The remaining 490 Zone system proposed for the Cantarini project loops within the proposed streets within the project and through the Holly Springs project. The proposed 16-inch 490 Zone water main in College Boulevard extending north from the proposed 36-inch transmission main to the northern end of the College Boulevard improvements is also a City of Carlsbad master planned capital improvement facility. The cost of constructing this facility will be bourne by the Carlsbad Municipal Water District. The redundant feed to the Cantarini and Holly Springs projects will be the proposed 16-inch 490 Zone water main which is currently under design in College Boulevard north of Cannon Road. Since this proposed pipeline will create a tie to the TAP DEXTER WILSON ENGINEERING, INC. PAGE 8 Bob Ladwig January 20, 2003 Reservoir water system in the Calavera Hills area, it can be used to backfeed the 490 Zone system in the Cantarini and Holly Springs projects if such a need occurs. System Pressures. Static water service pressures for building lots in the 490 Zone service area are expected to range between 65 psi and 126 psi within the Cantarini property. For the Holly Springs project, static water pressures will range from 47 psi to 97 psi. Table 2 below lists the Lot numbers on the Holly Springs project that are expected to have static water pressure less than 60 psi.

PAGE 9 Bob Ladwig January 20, 2003 For the highest lots within the Holly Springs project, consideration should be given to providing individual water booster systems for the homes above elevation 360 feet. Minimum water pressure at this elevation-based upon a 490 feet hydraulic grade line will be 56.3 psi. It is expected that the working pressure in the water system will be greater since the 490 feet hydraulic grade line represents the bottom of reservoir elevation. Nevertheless, even adding 20 feet to the operating hydraulic grade line will mean that house pads above elevation 370 will have pressures less than 60 frr esoi, individual water booster systems for the homes inthis area of the Holly Springs project should be considered. / _to e _4 Fire protection within the Holly Springs project is not a concern.. The computer analyses show that even, with a fire flow of 1,500 gpm in-the northeast corner, the highest area of the Holly Springs project, residual pressures are above 20 psi. 375 Zone. The 375 Zone will be connected to the proposed 12-inch water line stub in College Boulevard which is under construction by The Terraces project. This offsite 12-inch water line improvement will be extended north in College Boulevard to "A" Street within the Cantarini subdivision. A 12-inch 375 Zone water main is proposed to be extended north through the Cantarini project to "C" Street. This distribution main is being routed through the subdivision instead of in College Boulevard as proposed in the draft Water Master Plan Update (January 2003). This proposed alignment will allow the 12-inch main to be used for distribution as well as to function as part of the 375 Zone water system loop. The second source of 375 Zone water for the Cantarini subdivision will be the Carlsbad Municipal Water District funded 12-inch 375 Zone water line from El Camino Real east along Cannon Road to the College Boulevard intersection. From the intersection of "C" Street and College Boulevard, the Cantarini project proposes to build a 12-inch 375 Zone water main to connect to the District pipeline at Cannon Road. This will complete the 375 Zone water system loop on the east side of El Camino Real as presented in the Water Master Plan Update (January 2003). DEXTER WILSON ENGINEERING, INC. PAGE 10 Bob Ladwig January 20, 2003 The construction of the 375 Zone system will include a 12-inch stub westerly at the intersection of College Boulevard and "C" Street. This will provide for a future 375 Zone system loop through the proposed Rancho Carlsbad development. A second stub is proposed within the 375 Zone system. It is located in the future road extension south from "A" Street between "B" Street and "J" Street. This stub will allow for internal looping of the future deelopment property to the south of the Cantarini project. Finally, the 375 Zone system will be extended to the easterly end of"A" Street in order to provide for future extension into the Mandana property. North of "C" Street and adjacent to College Boulevard, the Cantarini project is proposing multi-family housings The water system for this area will require a 10-inch water loop to deliver the higher fire flows that will be necessary for this higher density product. The 10-inch loop is. proposed to be connected to the 375 Zone piping in "C" Street at two locations for water system redundancy. No 375 Zone facilities are located within the Holly Springs project. / (deThe proposed 375 Zone water system for the Cantarini pr&ect does incli\ the construction of a portion of 12-inch pi •ng p esented in the o Carlsbad Water Master Plan Update (January 2003) as a C funded facility. The a ter Plan Update shows the 12-inch 375 Zone pipeline I College Boulevard between The Terraces project and Cannon Road to be City funded. The Cantarini project is proposing to align a portion of this 12-inch pipeline through the subdivision as part of the project's distribution piping. Since this is a benefit to the Cantarini project, a cost sharing arrangement for this portion of piping can be negotiated between the Carlsbad Municipal Water District and the Cantarini project. Note that along the western portion of "C" Street there is some parallel piping needed. This is necessary to accommodate the redundancy needs for the multi-family portion of the. Cantarini project. DEXTER WILSON ENGINEERING, INC. . PAGE I I Bob Ladwig January 20, 2003 Static water service pressures for building lots in the 375 Zone service area will range between 73 psi and 111 psi within the Cantarim property. The pipe sizes shown on Exhibit A are adequate to provide domestic and fire flow requirements to the subdivision. The fire flow requirement for this project within the 375 Zone is 1,500 - gallons per minute for single-family dwelling units and is estimated to be 3,000 gpm for multi-family dwelling units. Reservoir Storage I Th Q ASLConsu Carisba ater Master Pla pdate, Volume III, October 1997, prepared by ting Engineers, disc ses both operational and emergency storage for the City's service area. Based up 1997 numbers from the Master Plan Update, there is a surplus of operationalst age of 10.2 million gallons, and a surplus of emergency storage of approxi tel 0 million gallons for existing conditions. Under ultimate demands for the City s ervice area, and without any new construction of storage facilities, there wou e a deficit of 10.8 million gallons for operational storage and 41 million gallons of emergency storage. . ç V0 AM The Master Plan Update rp6mends construction of additional storage facilities to account for the projected eficit in both operational and emergency storage capacities. As of this date, the C has not undertaken construction of any additional storage facilities. The A the does have a site for the recommended 8.5 million gallon 375 Zone "D" Tank, and ity's capital improvement program presently includes Project No. 33761 and 33762, "D" Reservoir Phase II, to be designed and constructed in Fiscal Year 2007-08. In addition, the capital improvement program includes Project No. 38191, TAP No. 2 Reservoir, for the 490 Zone system. Design and construction is scheduled for Fiscal Year 2005-06. The location of the TAP No. 2 Reservoir will be on the Carlsbad Municipal Water District's property at the Maerkle Reservoir site. DEXTER WILSON ENGINEERING, INC. PAGE 12 Bob Ladwig January 20, 2003 Recommendations The following recommendations and conclusions are made based on the water system analyses performed for the Cantarini and Holly Springs projects. The Cantarini and Holly Springs projects will be served by the 490 Zone and the 375 Zone systems extending from existing College Boulevard east of El Camino Real and from the future Cannon Road and College Boulevard intersection. Exhibit A presents the recommended water system layout and water line sizes for both projects. Static pressures within the Cantarini project will range between 73 psi and 111 psi in the 375 Zone, and 65 psi and 126 psi within the 490 Zone. Static pressures within the Holly Springs project will range betwee 4'7.p i and 97 psi within the 490 Zone. Consideration should be given to stalling individual water booster systems in the homes within the Holly Springs project above elevation 360 feet. The alignment of the proposed 36-inch parallel main to the existing 27-inch 490 Zone transmission line from Maerkle Reservoir to El Camino Real is. proposed in College Boulevard and "A" Street through the Cantarini project. This is a capital improvement project for the Carlsbad Municipal Water District and will be funded by the District. In addition, the proposed 16-inch 490 Zone pipeline in College Boulevard is a master planned facility and will be funded by the Carlsbad Municipal Water District. This 16-inch 490 Zone pipeline is to be extended north to the intersection of Cannon Road as part of the improvements constructed by the Cantarini and Holly Springs projects. DEXTER WILSON ENGINEERING, INC. PAGE 13 Bob Ladwig January 20, 2003 The water lines within the Cantarini and Holly Springs projects must be designed to meet AWWA C900 Class 150 for PVC pipe. Portions of the proposed water lines in College Boulevard, "A" Street, and "C" Street must be designed to meet a working pressure of greater than 150 psi. Within the 490 Zone service area, building service pressure regulators are recommended for all pads in the Cantarini project below elevation 330 feet in order to maintain building service pressures below 80 psi in ac' cordance with the Uniform Plumbing Code. Within the 375 Zone service area, building service pressure regulators are recommended for all pads in the Cantarini project below elevation 191 feet in order to maintain building service pressures below 80 psi in accordance with the Uniform Plumbing Code. Building service pressure regulators are recommended for all pads in the Holly Springs project below elevation 330 feet order to maintain building service pressures below 80 psi in accordance with the Uniform Plumbing Code.

January 17, 2003 726-001 Ladwig Design Group 703 Palomar Airport Road, Suite 300 Carlsbad, CA 92009 Attention: Bob Ladwig, President Subject: CantarinilHolly Springs Project Water Study Comments from Pountney Consulting Group, Inc. This letter provides a written response to the comments on the September 20, 2002 Water System Analysis for the Cantarini and Holly Springs Projects in the. City of Carlsbad. The comments were generated by Pountney Consulting Group, Inc. in a letter to Mooney & Associates dated November 4,-.-20,02. A copyof the letter is attached and the study comments are numbered and addressed below. Water System Design Criteria: We contacted the City of Carlsbad Public Works-Engineering Department and requested and received a copy of the Water Planning Criteria. The revised water study design criteria are in conformance with this Water Planning Criteria. The revised water study peaking factor design criteria are in conformance with the -City of Carlsbad Water Planning Criteria.. The maximum day peaking factor is 2.5, and the peak hour peaking factor is 4.0. 703 PALOMAR AIRPORT ROAD, SUITE 300 • CARLSBAD. CA 92009 • (760) 438-4422 0 FAX (760) 438-0173 Bob Ladwig January 17, 2003 Page 2 Projected Water Demands: The revised water study uses 200 gpd/capita average demand. The population density is taken from the Zone 15 Facilities Plan, Exhibit 16 titled, "Zone 15 Buildout Population Projections." The population index far all General Plan Land Use designations is 2.3178 people per dwelling unit. A copy of this exhibit is attached to this letter. Per Exhibit 16 of the Zone 15 Facilities Plan, the population index is the same for all General Plan Land Use designations. The revised water study uses the residential water demand factors in the City of Carlsbad Water Planning Criteria. Fire Flow Requirements: Fire flow demands are changed in the revised water study to conform with the City of Carlsbad Water Planning Criteria. For residential development, the fire flow requirement is 1,500 gpm from any two hydrants. The revised water study's computer model simulates a 1,500 gpm fire flow out of a single hydrant for both the single family and multi-family residential areas. However, for the multi-family residential area, two hydrants are tested simultaneously to simulate a 3,000 gpm fire demand. While we do not currently have the City of Carlsbad Fire Prevention Department fire flow requirements (see next item), we do expect that the fire flow demand will be greater than for single family residential development. 7. The process of tentative map approval for the Cantarini/Holly Springs projects• includes $ubmitting the proposed map to the Fire Prevention Department of the City of Carlsbad for fire hydrant layout and fire. flow re'quirements. This process is currently underway and as of the date 'of this response letter, approved fire Bob Ladwig January 17, 2003 Page flow requirementsand hydrant layout has not been determined. The proposed fire hydrant layout is shown on the proposed tentative map. We believe it is not prudent to show the locations of fire hydrants on Exhibit A or B of the water study because it is likely that through the tentative map process and the final engineering design the locations of some hydrants may change. These water study map exhibits cannot keep current with the fire hydrant locations, nor are they intended to provide this type of information. The water system analysis provided by the water study is not specific to a certain fire hydrant layout but can accommodate the fire hydrant flow requirements at all locations throughout the two proposed projects. Thus adding fire hydrants to the exhibit would not provide pertinent information and may confuse the issue if the locations are not consistent with the ultimate locations approved for the tentative map. Existing Water System: An additional exhibit has been included in the revised water study as requested. Information on who is constructing the future reaches of the 36-inch transmission main is not currently available, nor is it known when these reaches will be constructed. It is expected that as the properties to the east of the Cantarini project develop they will construct the extension of the 36-inch transmission main until it is completed to the Maerkle Reservoir. During the 36-inch main construction, the existing 27-inch pipeline must remain in service. The portion of the 36-inch 490 Zone transmission main to be constructed by the Cantarini project will be a dead end main until future extension to the east through the Mandana property. During this interim time period, redundancy for the Cantarini project will be provided through the 16-inch 490 Zone water line which extends to the Tap Reservoir service area. If necessary, this 16-inch main in College Boulevard can be used to back-feed the Cantarini project with 446 Zone water from the Tap Reservoir.: Bob Ladwig January 17; 2003 Page 4 General: We have tried to make sure that all the references in the report now indicate which edition of the master plan update is being referred to. Primarily the references are to the January 2003 first draft of the master plan update. While the new master plan update is only at the first draft level (dated January 2003), we have spoken with Dudek & Associates who prepared the report and adjusted our proposed water system for the Cantarini and Holly Springs projects to be in line with the draft master. plan update. In addition, we received comments on this water study from William E. Plummer, City of Carlsbad, Deputy City Engineer, Design Division. Incorporating Mr. Plummer's comments brought this report to be in line with the water master plan update's approach. For a discussion of Mr. Plummer's comments, please see the response letter to Mr. Plummer in Appendix E of the revised water study. Please feel free to contact us if you have any additional questions about the comments to our water study or to clarify any of our project recommendations. We look forward to continuing to work with you through the planning process for the Cantarini and Holly Springs projects. : Dexter Wilson Engineering, Inc.

Please add a discussion noting the source of all the criteria used for the study. 2 • Per the City Planning Criteria, the peaking factor should be 2.5 for max day demand. The report used 2.0 for max day. The report should either use the 2.5 max day demand factor or explain why it is not being used and how the 2.0 factor was derived. Projected Water Demands 3 . Provide ca1ulafions showing how the 550 gpd/unit.were calculated. Show zoning/land use data with population per dwelling unit. Lf . Why is 550 gpd/unit.being used for both the single family units and the multi-family units? Usually, multi-family unit demand is less than single family because the population per unit is less. The City of Carlsbad Water Planning 'Criteria uses 200 GPD average daily flow per Capita. Fire Flow Requirements Provide how the fire flow demands were derived. 7 . The local Fire Marshal must be contacted to verify fire flow requirements and the location of proposed fire hydrants. Show proposed fire hydrant locations on Exhibit B.

The map should note the existing 27" line and the proposed future 36" 490 Zone and 12" 375 Zone pipelines. Note on the map who is constructing each reach of these pipelines and when they will be completed. Show the location of the Terraces, Cantarini, Holly Springs, Mandana, and Kato Projects. From Exhibit A, it is unclear as to what is existing and where the existing system goes. Will the 36" be looped when the development is connected? General • The City of Carlsbad is currently in the process of updating their Water Master Plan. The water study references the Carlsbad Water Master' Plan Up-date a few times, but it is unclear in a couple of cases whether this is thenew up-date or based on the 1997 up-date. Please clarify. . Before the Cantarini Water Study is approved, it should be verified that the proposed water system improvements are in accordance with the new Carlsbad Water Master Plan Up-date. • If you have any questions, please call us. • • Thank you, • : - POUNTNEY CONSULTING GROUP, INC. .By Sandra J.

A copy of the memorandum is attached to this response letter. The memorandum addressed both'the domestic water study and the recycled water study. This letter will address only the comments regarding the domestic water study. The recycled water study comments will be addressed in a separate letter. The review comments for domestic water are numbered and addressed below. Domestic Water: This change is made in the revised water study. This change is made in the revised water study. 703 PALOMAR AIRPORT ROAD, SUITE 300 • CARLSBAD, CA 92009 • (760) 438-4422 • FAX (760) 438-0173 Bob Ladwig January 17, 2003 Page 2 Exhibit A of the revised water study includes a note on the map which identifies the lots with less than 60 psi static pressure based upon a 490 hydraulic grade line. In the text of the revised water study, we have included a table, Table 2, which provides the datarequested in this comment. All discussion of new pressure reducing stations. has been removed from the revised water study. The revised discussion includes the 12-inch 375 Zone piping loop in Cannon Road and College Boulevard consistent with the January 2003 draft water master plan update. The revised Exhibit A shows an 8-inch 375 Zone pipeline extending to the east property line in "A" Street. There is also a 10-inch main shown to extend to the southern subdivision boundary in "E" Street. It is not likely that a future connection will be made by future development to the south of the Cantarith project in "B" Street; therefore, a extension to the subdivision boundary is not' being shown. This change is made in the revised water study. The information provided in this comment has been incorporated into the revised water study under the "Reservoir Storage" section. The references to the City of Carlsbad have been changed to the Carlsbad Municipal Water District. The requirement to extend the 16-inch 490 Zone pipeline to Cannon Road has been included in Item 4 of the Conclusions. Bob Ladwig January 17, 2003 Page3 . Please feel free to contact us if you have any additional questions about the comments to our water study or to clarify any of our project recommendations. We look forward to continuing to work with you through the planning process for the Cantarini and Holly Springs projects. . . Dexter Wilson Engineering, Inc. Andrew Oven AO:ndg Attachment November 12, 2002 TO: JEREMY RIDDLE, ASSOCIATE ENGINEER FROM: Deputy City Engineer, Design Division DOMESTIC WATER AND RECYCLED WATER SYSTEM - ANALYSIS CANTARINI AND HOLLY SPRINGS PROJECTS The domestic water and recycled water system analysis for the subject project dated September 20, 2002 and September 24, 2002, respectively, was prepared by Dexter Wilson Engineering, Inc. A review of the analysis has been completed. Following are our comments. Domestic Water On page 4,. at the end of the second paragraph, delete the words "Carlsbad Public Works Department" and substitute the words, "Carlsbad Municipal Water District". All reimbursement funding for water and recycled water systems. will- be from the District and not the City's Public Works Department. On page 5, last paragraph, last sentence, delete the words, "Carlsbad. Public Works Department" and substitute, "Carlsbad Municipal Water' District". On page 6, second paragraph, it states some homes will have less pressure than 60 psi in the 490-pressur zone. These lots shall be shown or highlighted on the map and the number of lots impacted shall be listed in a table comparing ground elevation with available pressure. . On page 6, under- the title 375 Zone, delete -the use of two new pressure reducing stations and indicate that the 375 pressure zone shall be looped by constructing a '12" diameter pipeline in College Boulevard proceeding north 'from "C" Street. to the intersection, of -College Boulevard and Cannon Road. The District. -will have a 375-pressure zone pipeline and 'supply at this intersection when the developer f Calavera Hills Villages constructs Cannon Road. Conditions shall be placed on future development along this reach indicating that they shall' reimburse the developer of Cantarini for this pipeline. On page 7, .extend the 375-pressure zone pipeline in "A" Street and "B" Street to the development boundary. Future development east and south of the development boundary will need the 375-pressure zone. On page 8, delete-the discussion of the proposed pressure reducing stations. Extending the 375-pressure zone pipeline in College Boulevard as.. noted previously will loop the system. e On page 9, in the last sentence of the first paragraph, delete the words, "there is no current capital improvement project funded for its design and construction." The capital improvement program presently includes Project No. 3376.1 and 33762 "D" Reservoir Phase II to be desighed and constructed in FY 2007-08. In addition, indicate that the CIP also includes Project No. 38191 "Tap No. 2 Reservoir" for the 490-pressure zone. Design and construction is scheduled for fiscal year 2005-06. The location of this reservoir will be on the Ditrict's property located at the Maerkle Reservoir site. On page 9, item 4, delete references to the "City of Carlsbad" or "City" and substitute the words, "Carlsbad Municipal Water District". Also, add that the developer shall extend the 16" diameter 490-pressure zone pipeline, from the tract boundary north to the intersection of Cannon Road and College Boulevard. The District will reimburse the developer for this pipeline. Recycled Water 1. On page 3, .first paragraph.; delete the last sentence and add .the following: The District will have a 16" recycled water pipeline in Cannon Road and a 12" recycled water pipeline in College Boulevard at Cannon Road. Plus, the Distriôt's existing "C" Tank Reservoir is being converted to recycled water storage. On page .3, second paragraph. It is correct that the District will not have a higher-pressure zone available, to this area; howecier, a local booster pump can be installed to boost the pressure from the lower 384-pressure zone. On page 4, first paragraph, indicate that higher elevation can install a booster pump thàt•.would be activated only when the irrigation system is activated: On the map, show any common areas that will have non-native landscaping installed where recycled water could be used Indicate the potential area and water demand. • On page 6, second paragraph, add the following: The. 12" recycled water pipeline shall be extended north in College Boulevard and connect to the recycled pipeline at the intersection of'College Boulevard and Cannon Road. .
