Infrastructure Services Group 16241 Laguna Canyon Road, Suite 200 Irvine, CA 92618 (949) 727-7099 c52A DISCUSSION Purpose for Project This hydrology report is for the Carlsbad 50-MGD Desalination Plant. The project site is located in San Diego County, City of Carlsbad. The site is located on the grounds of the Encina Power Station. The power station is bounded by the Pacific Ocean and Carlsbad Boulevard to the west, the Carlsbad State Beach and Agua Hedionda Lagoon to the north, the 1-5 Freeway to the east, and Cannon Road, an SDG&E maintenance yard, and adjacent residential areas to the south. Refer to Figure 1 and Figure 2 for the site and vicinity maps, respectively. The existing runoff is typically surface flow through the site or falls within containment berms for percolation and evaporation. The desalination facility will have a capacity to deliver approximately 50 million gallons of drinking (potable) water per day. This report will present hydrology for the existing, interim and proposed conditions. The proposed condition accounts for a 50-MGD Desalination Plant placed on the project site along with associated improvements. The interim condition evaluates rough grading of the site. The evaluated storm is the 10-year storm event, although the 100-year storm event will also be analyzed for overflow design purposes. The report will evaluate the following: Determine the existing flowrate and volume of water for the site for a 10-year storm event. Determine the interim condition flowrate and volume of water for a 10-year storm event. Determine the proposed condition flowrate and volume of water for a 10-year storm event. Storage volume required to hold the 10-year storm event. Calculate 100-year storm event overflow rates. Hydrology Report Page 1 10/6/2009 Carlsbad Desalination Plant Tetra Tech, Inc.

Figure 2— Vicinity Map PROPOSED DESALINATION PLANT SITE BOUNDARY AGUA HEDIONDA LAGOON PACIFIC OCEAN Description of Watershed Existing Condition The existing site consists of tanks, pipes, containment berms, paving, vegetation and other improvements related to the Enema Power Station. The site generally slopes from the northeast to the southwest. The existing drainage is collected within containment berms or drains into a local storm drain system that flows to the Agua Hedionda Lagoon. An exhibit (Figure 3) showing the existing conditions may be found at the end of this report. Interim Condition The interim condition consists of an excavation for a proposed underground tank and a gently graded pad. Runoff from the gently sloping pad will be stored in an adjacent bermed containment basin, similar to the existing condition. Water entering the excavation for the underground tank will be either allowed to Hydrology Report Page 3 10/6/2009 Carlsbad Desalination Plant Tetra Tech, Inc. percolate into the ground or pumped into the above mentioned basin. An exhibit (Figure 4) showing the interim conditions may be found at the end of this report. Proposed Condition The proposed site consists of a 50-MGD desalinization plant, paving, water tanks, retaining walls and landscaping. The improvements will increase the amount of impervious surfaces. An exhibit (Figure 5) showing the proposed conditions may be found at the end of this report. Methodology The site hydrology was analyzed utilizing the Rational Method found in the San Diego County Hydrology Manual, June 2003. The watershed for this project is less than 1 square mile so the Rational Method is acceptable for peak discharge calculations. The volume of water capable of being stored in the adjacent bermed containment basin was obtained utilizing AutoCAD Civil 3D 2008. A freeboard value was assumed to be 2 feet, giving a maximum water surface elevation of 39 feet. The various drainage areas and other pertinent hydrology data were determined utilizing existing and proposed site data. All three development stage watershed geometric information maps (Figures 3, 4, and 5) may be found later in this report. The proposed condition was split into two subdrainage areas, Area A to the north and Area B to the south, as indicated on the watershed geometric information map for the proposed condition. The development of the site results in an increase in the impervious area which will increase runoff volumes and peak discharges. The excess peak storm volume from the 10-year, 6-hour duration storm will be contained on site through the use of underground storage detention devices. Once in the detention devices, the water will infiltrate into the ground. For storm events larger than 10 years, storm water from Area A and a portion of Area B will exit the site and flow into the existing abandoned oil containment basin where the water will percolate into the ground, similar to the existing condition. Excess water leaving from Area B, not collected, will discharge into the existing drainage Hydrology Report Page 4 10/6/2009 Carlsbad Desalination Plant Tetra Tech, Inc. channel which flows into the Agua Hedionda Lagoon to the north, similar to the existing condition. A Microsoft Excel workbook was used in conjunction with the San Diego County Hydrology Manual to model the watershed. The point rainfall depths used for the analysis were obtained from the NOAA Atlas 2. The isopluvials maps used may be found in the San Diego County Hydrology Manual and are also attached at the end of this report as Figures 6 through 10. Intensity for the 6- hour storm can be found using the equation I = 7.44P6D045 where P6 is the 6-hour storm rainfall amount and D is the duration in minutes. This equation only applies to the 6-hour storm. P6 should be between 45% and 65% of P24. If not, P6 can be adjusted before applying to the equation. The rainfall distribution used for this analysis is the 24-hour hypothetical distribution as described in the Hydrology Manual. Descriptions of the soils present on the watershed are contained in the Hydrology Manual. Based on those soil surveys, there is one type of soil in the watershed, Group Permanent vegetated areas have been classified as Open Brush, a "c" value of 0.25, and paved areas, buildings, equipment and other similar objects have been considered as impermeable, a "c" value of 0.90. A "c" value of 0.25 was used for the interim development due to erosion control measures that will be used. These "c" values are from the Hydrology Manual. The adjusted "c" values for the various watershed areas were calculated using the method described in the Hydrology Manual. Summary Rational Method peak flows along with storm volumes are developed for three conditions, as follows: Pre-Development Condition Interim Development Condition Post-Development Condition Hydrology Report Page 5 10/6/2009 Carlsbad Desalination Plant Tetra Tech, Inc. All of the above models are prepared for the 10-year, 6-hour storm event. Pre-development conditions are defined as those that existed at the time of commencement of the study (July 2009). The post-development condition is based on the assumptions that 1) the off-site watershed is assumed to match the pre-development condition land-use; and 2) the on-site area is fully developed. The results of the models are summarized in Table 1 below: Table 1— Rational Method Peak Flows and Peak Volumes 10—Year Storm Event 100 -Year Storm Event Model Peak Discharge Volume Peak Discharge Volume Pre-Development Area A 4.84 cfs 5,663 cf 6.73 cfs 7,865 cf Area 5.89 cfs 6,703 cf 8.18 cfs 9,310 cf Area C 4.47 cfs 4,985 cf 6.21 cfs 6,923 cf Total 15.20 cfs 17,351 cf 21.12 cfs 24,098 cf Interim Development Area A 4.09 cfs 6,994 cf 5.67 cfs 9,714 cf Area B 4.24 cfs 3,395 cf 5.89 cfs 4,715 cf Total 8.33 cfs 10,389 cf 11.56 cfs 14,429 cf Post-Development Area 12.03 cfs 18,445 cf 16.71 cfs 25,618 cf Area B 6.28 cfs 10,630 cf 8.72 cfs 14,764 cf Total 1 18.31 cfs 29,075 cf 1 25.43 cfs 40,382 cf The volume of water storage available for the interim development is 161,480 cf, in the existing offsite bermed containment basin, which is adequate to store the 10-year and 100-year events without any overtopping of the basin. A desilting trap is implemented to convey the runoff from the site into the existing basin. The desilting trap size has been calculated per the recommendations contained in the Caltrans Construction Site Best Management Practices Manual, Sediment Trap SC-3. For the post-development condition it is proposed to use vegetated bio-swales, permeable paving, and an underground storage and percolation system such as CUDO 4 Units manufactured by Cudo Stormwater Products, Inc. (or equal). The proposed site is required to store approximately 11,725 cf (the storage required to maintain the same runoff flows of the 10-year storm event for the pre- and post-development conditions). Each unit is capable of storing 30.8 cubic feet of water and is 2 feet x 2 feet x 8 feet tall. Hydrology Report Page 6 10/6/2009 Carlsbad Desalination Plant Tetra Tech, Inc. wce 'e/Lf bcvot1i/peiv. P4ueeie.4-. A total of 11,725 cf of storage is provided through the u4iits. This onsite underground storm water storage system is fully capable of collecting nd treating all flows y the 85th percentile storm (Ca culations are provided in Appendix 1). Inlet were sized using FlowMaster to convey the resulting runoff of the 10-year storm event. The results can be found in Appendix 1. Outlet structures and pipes are incorporated into the design to release the storm water to the existing underground storm drain located in the access road. The outlet structure, which has a crest height of six feet, was sized using FlowMaster (see Appendix 1). The location and storage capacity of the units are indicated on the watershed geometric information map (Figure 5) for the proposed condition. In addition to the CUDO units, two Low Impact Development (LID) methods are implemented into the site: vegetated bio-swales and permeable Asphalt-Concrete (AC) pavement. As required by the County of San Diego's Standard Urban Storm Water Mitigation Plan (SUSMP), these facilities will mitigate the 85th percentile storm. The same method described earlier was used to determine the flows produced by the 85th percentile storm, which produces 0.6 inches of rain as shown in the rainfall isopluvials map from the San Diego County Hydrology Manual (attached as Figure 10 of this document). Calculations in Appendix 2 show how the vegetated bio-swales and permeable pavement can mitigate the 85th percentile storm flows. These facilities were designed with the help of the County of San Diego's Low Impact Development Handbook. The bio-swales are composed of bioretention material (sand/compost mix), 6 inches of washed sand, a 4-inch perforated underdrain pipe encased with open-graded gravel and an impermeable geotextile liner over the native soil to prevent infiltration that undesired due to the proximity of building foundations and the subsurface tank. The bio-swale in Area A (Figure 11) has 24 inches of bioretention material, whereas the bio-swale in Area B has 18 inches. This difference is due to space constraints. Since there is very little space for the bio-swale in Area A, the bioretention material had to be deeper in order to mitigate the 85" percentile storm. The bio-swales were also sized to allow for a 6-inch minimum freeboard. To determine the amount of runoff treated and stored by the bio-swales, a porosity of 30% was used. Refer to Table 1 of Appendix 2. The permeable pavement for Hydrology Report Page 7 10/6/2009 Carlsbad Desalination Plant Tetra Tech, Inc. this site consists of 3 inches of asphalt, 3 inches of #4 aggregate, 18 inches of 1.5" washed aggregate (9 inches of which serves as the reservoir), a 4-inch perforated underdrain pipe encased with open-graded gravel and an impermeable geotextile liner over the native soil to prevent infiltration that undesired due to the proximity of building foundations and the subsurface tank. To determine the amount of runoff treated and stored by the permeable pavement, a porosity of 40% was used. Refer to Table 2 of Appendix 2. Note that the calculations in Appendix 2 only show the storage volume provided by the media directly below the bottom of the BMP and does not include the side slopes. Also note that the calculations for the permeable pavement only accounts for the 9-inch reservoir layer. The calculations also do not include the capacity of the underdrain pipes, which are placed to convey the stormwater to the CUDO units. The vegetated bio-swales and permeable pavement areas are sized to filtrate the 85th percentile storm. The bio-swales were also sized, using FlowMaster, to capture the portion of discharge produced by the 100-year storm in its respective areas. Refer to Appendix 2 for typical Vegetated Bio-Swale and Permeable Pavement Details and the bio-swale FlowMaster Reports. Runoff flows that are larger than the 85th percentile storm will be routed to 3-foot diameter steel pipe inlets (San Diego Regional Standard Drawings D-16 attached in Appendix 2) which are connected to the CUDO unit. FlowMaster was also used for these inlets to calculate their discharge capacities. The capacities were calculated using the orifice conditions as well as the weir conditions. As found in Appendix 2, the FlowMaster Reports show that these pipe inlets are fully capable of capturing the discharge produced by the 100-year storm. Based on the calculations, the bio-swale in Area A requires two steel pipe inlets while the bio-swale in Area B only requires one. As a part of the underdrain system, cleanouts will be installed to easily facilitate cleaning and for observation to verify that there is no standing water. In the event of a 100-year storm, the overflow will bypass the CUDO units. Excess water from Area A (of Figure 5) will flow into the adjacent bermed containment basin. Excess water from Area B will flow offsite. Hydrology Report Page 8 10/6/2009 Carlsbad Desalination Plant Tetra Tech, Inc.

WATER STORAGE SYSTEM CUDOTM Stormwater Cube (Underground Retention / Detention / Infiltration / Water Reuse Systems) Operations and Maintenance Manual Version 1.00c - November 05, 2008 21 Page - CUDOTM O&M Manual CUDOTM Stormwater Cube - Modular Stormwater Systems Description / Basic Function CUDOTM is a modular stormwater system comprised of a grouping of modular polypropylene or concrete cubes that when constructed form an underground storage area for stormwater. This system can be used for infiltration, retention, detention or water reuse. CUDO can help achieve runoff detainment and storage to help attenuate the peak flow to pre-construction levels and can help conform to current Low Impact Development requirements. Infiltration The purpose of a CUDCITm infiltration system is to capture stormwater runoff, store the runoff, and then allow it to percolate into the ground via the open space area of the cubes and perforations in the side wall. The system is backfilled with a Class I material defined by ASTM D2321 as a cleaned open graded rock or a Class II permeable sand. The rock or sand provide additional storage capacity but also allow for a percolation interface with the native material. The ground water is "recharged" with this type of system. Detention The purpose of a CUDOTM detention system is to capture stormwater runoff, store the runoff, and then allow it to be released at a controlled rate through an appropriately sized orifice control. A detention system helps attenuate the peak flow from the site assuring that pre-development runoff flows are not exceeded as a result of the development. A CUDOTM detention requires the cubes to be encapsulated with an impermeable liner for the polypropylene system or the seams of the concrete system to be sealed with a water proof mastic. Retention A CUDO retention system is a hybrid system. It is a combination of a detention system and an infiltration system. A retention system is utilized to attenuate peak flow as well as promote groundwater re-charge. A retention system is outfitted with an overflow pipe at the top of the system which allows the system to fill for infiltration but also outlet if the ground is saturated. Water Reuse The purpose of a water-reuse CUDOTM system is to capture and store water for future use. The system is constructed in a similar fashion to a detention system but instead of a controlled outlet the system is constructed with an emergency overflow. A water reuse system is a LID device that helps attenuate peak flows as well as conserve water. Water may be reused through an active pump system or passive irrigation. lnspection/Cleanout Ports Inspection and cleanout ports are 18-inch diameter vertical risers connected to the uppermost polypropylene CUDOTm cubes or up to 30-inch manhole access connected to the concrete CUDO. They are used for entrance into the system, or for access to place vacuum truck hoses or water-jetting devices or CCTV equipment. Ports are strategically located near inlet and outlet pipes and in other areas or probable deposition in the system. It is recommended to keep surface level access lids sealed and bolted at all times when the system is in service. Inlet Bay Some systems are configured so that pretreatment of the stormwater occurs within the CUDO system. In this case the CUDOTm system will house an inlet bay. The inlet bay is separated from the rest of the CUDO system by sidewall plugs and is intended to separate gross pollutants, trash and debris and floatables from the CUDOTM system and pre-treatment device. The bay contains its own sump area and unique access ports. cudo Stormwater Products, Inc. P.O.

The purpose of maintaining a clean and obstruction free CUDO system is to ensure the system performs the intended function of the primary design. Trash and debris, floatables, gross pollutants and sediment can build up in the CUDO leading to clogging of the native soil interface or blockage of the inlet or outlet pipes. This can cause the system to function improperly by limiting storage volume, limiting the design percolation rates or impeding flow in and out of the system. Downstream and upstream, areas could run the risk of flooding and deleterious environmental impact. Recommended Frequency of Service It is recommended that the CUDO stormwater systems be serviced on a regularly occurring basis. Ultimately the frequency depends on the amount of runoff, pollutant loading, and interference from trash, debris and gross pollutants as well as proper maintenance of upstream pretreatment devices. However, it is recommended that each installation be inspected at least two times per year to assess service needs. Recommended Timing of Service Guidelines for the timing of service are as follows: For areas with a definite rainy season the system should be serviced prior to and following the rainy season. For areas subject to year-round rainfall service should occur on a regularly occurring basis. (A minimum of two times per year.) For areas with winter snow and summer rain the system should be serviced prior to and after the snow season. For installed devices that are subject to dry weather flows only (i.e. wash racks, parking garages, etc...) the unit should be serviced on a regularly occurring basis. (A minimum of two times per year.) Inspection An inspection should be performed when the system is new. This allows the owner to establish a baseline condition for comparison to future inspections. Sediment build up can typically be monitored without entering the system. (No confined space entry.) Initial and subsequent inspection data should be recorded and filed for reference. Some regulatory agencies require that the results of the inspections be documented and reported. Inspection reports should comply with regulatory requirements and be submitted as required. Inspection Procedures Locate the inspection, cleanout and access ports. Inspection and cleanout ports are typically 18-inch diameter. Access ports are typically 24-inch or 30-inch diameter. Pictures should be taken to document the location or a site map should be generated to detail the as-built locations of the ports. Unbolt and remove the access port lids. Insert a measuring device into the opening making note of a point of reference to determine the quantity of sediment and other accumulated material. If access is required to measure, ensure only certified confined space entry personnel having appropriate equipment are allowed to enter the system. In addition, for accessible concrete CUDOTm systems personnel should utilize appropriate confined space entry procedures to enter the system and photograph its condition. Inspect inlet and outlet locations for obstructions. Obstructions should be removed at this time. Fill in the CUDOTM Inspection/Maintenance Data Sheet and send a copy to the regulatory agency if necessary. Maintenance Cudo Stormwater Products, Inc. P.O.

In the event of a spill of a foreign substance, cleanout of the system should be considered. Maintenance Procedures Locate the inspection, cleanout and access ports. Inspection and cleanout ports are typically 18-inch diameter. Access ports are typically 24-inch or 30-inch diameter. Pictures should be taken to document the location or a site map should be generated to detail the as-built locations of the ports. Unbolt and remove the access port lids. Measure the sediment buildup at each port. If access is required to measure ensure only certified confined space entry personnel having appropriate equipment are allowed to enter the system. A thorough cleaning of the system (inlets, outlets, ports, and inlet bays) shall be performed by either a vacuum truck or by manual methods. Inspect inlet and outlet locations for obstructions. Obstructions should be removed at this time. Inspect the structural components of the system. Fill in the CUDO Inspection/Maintenance Data Sheet and send a copy to the regulatory agency if necessary.

The parking lots will be located at the northwest corner and southwest corner of the site. The retention basins will extend down to Elevation 30 feet. In accordance with your request, we have prepared this project memorandum to provide the estimated percolation rates of the subsurface soils at Elevation 30 feet at these locations. No percolation test was performed at the site. Based on the available borings, the parking lot at the northwest portion of the site is expected to be underlain by bedrock at Elevation 30 feet. The bedrock consists of silty to clayey sandstone and the percolation rate is estimated to be on the order of 0.01 inch per hour. The parking lot at the southwestern portion is expected to be underlain by fill consisting of silty sand and the percolation rate at Elevation 30 feet is estimated to be on the order of 0.1 inch per hour. If you have any questions regarding this project memorandum, please do not hesitate to contact this office. We appreciate this opportunity to be of service.
