Section 1 Project Information 1.1 Project Data Project Owner: Project Site Address: APN Number(s): Parcel Area: lonis Pharmaceuticals, Inc 2855 Gazelle Court, Carlsbad CA 92010 Intersection of Whiptail Loop and Gazelle Court 209-120-22 and 23 8.1-acres Project Disturbed Area: 8.1-acres 1.2 Scope of Report Drainage Study lonis Lots 21 and 22 This report includes analyses of 100-year 6-hour project-site peak flow under existing and proposed conditions. This report documents the hydrologic impact of the proposed improvements, as compared to the existing condition; and includes preliminary sizing for attenuation measures required to mitigate peak flow. This report does not address temporary Best Management Practices (BMPs) required during construction, refer to the project Storm Water Pollution Prevention Plan (SWPPP). A SWPPP will be prepared by Michael Baker International at a future date. Post Construction BMPs are addressed in the project Storm Water Quality Management Plan (SWQMP). A SWQMP was prepared by Michael Baker International in June 2021. 1.3 Project Description This report discusses the hydrology and hydraulic design for lonis Lots 21 and 22. Proposed improvements include one new structure along with accompanying parking structure, surface parking lots and hardscape. Total project-site impervious area will be increased as a result of the proposed improvements; however, peak flow associated with the 100-year 6-hour event will be mitigated to at or below existing rates through proposed biofiltration basins and sub-terranean detention vaults . Based on the Natural Resources Conservation Service's (NRCS) Websoil Survey, the project site is comprised entirely of Cieneba coarse sandy loam, 15 to 30 percent slopes, eroded (hydrologic soil type D) . The Federal Emergency Management Agency (FEMA) has not mapped a Special Flood Hazard Area (SFHA) within the project site vicinity. The entire project site lies within un-shaded Zone X, which correlates with areas determined to be outside the 500-year floodplain. An exhibit is provided in Appendix A of this report . 1 1.4 Existing Conditions Drainage Study lonis Lots 21 and 22 The project site consists of two previously graded lots that are all natural with some vegetation and has been hydrologically analyzed as two drainage areas. Drainage Area 1 is approximately 4.2-acres and includes the upper lot (Lot 21). Runoff sheet flows along the graded pad in a southwest direction and collected by an existing detention basin which ultimately discharges into the existing storm drain and conveyed west. Drainage Area 2 is approximately 3.9-acres and includes the upper lot (Lot 22). Runoff sheet flows along the graded pad in a southwest direction and collected by an existing detention basin which ultimately discharges into the existing storm drain and conveyed west. Impervious area is comprised of the concrete outlet structure in the existing basins. Pervious area is comprised of landscape located within parking islands and adjacent to the existing building. Refer to Appendix B for an exhibit detailing the existing condition. 1.5 Proposed Conditions Newly proposed structures for commercial use are proposed throughout the project site. Roof leaders, area drains, and new on-site private storm drain will direct project site runoff to proposed storage vaults or biofiltration basins, described in more detail below. The project site is entirely built out in the proposed condition and has been hydrologically analyzed as 6 drainage basins. Drainage Area 1 is approximately 0.9-acres and includes the southeastern portion of the project site consisting of the front driveway and roundabout. Runoff is collected via curb inlets and piped to a biofiltration basin (Biofiltration Basin 1). The basin has a footprint of approximately 2,000 square feet and a 0.75" orifice. Drainage Area 2 is approximately 1.2-acres and includes a portion of the main building, the eastern most portion of the surface parking areas and driveway, and surrounding landscape. Runoff is collected via roof drain inlets and curb inlets and routed to a modular wetland (Modular Wetland 1) for water quality treatment and then piped to a separate concrete storage vault (Storage Vault 1). The vault has a volume of approximately 4,530 cubic feet at the weir height, with a weir 4" above the vault bottom and a 1" orifice. Drainage Area 3 is approximately 2.1-acres and includes the northernmost portion of the project site, including a portion of the main building, northern most parking area, and surrounding landscape. Runoff is collected via curb inlets and piped to a modular wetland (Modular Wetland 2) for water quality treatment and then routed to a separate concrete storage vault (Storage Vault 2). The vault has a volume of approximately 7,850 cubic feet at the weir height, with a weir 4" above the vault bottom and a 1" orifice. Drainage Area 4 is approximately 0.6-acres and includes the parking structure and surrounding landscape. Runoff is collected via sloped surface and piped to a biofiltration basin (Biofiltration Basin 2). The basin has a footprint of approximately 1,581 square feet and a 1" orifice. Drainage Area 5 is approximately 1.7-acres and includes the western portion of the project site, including a portion of the main building, northwestern parking area, and surrounding landscape. 2 ... .. .. .. 111111 ... ... ... ... ... .. ---... ... ... --.. .. ... .. .. .. .. .. _, - - ... ... -... -... ,.. -... ... -.. -.. --.. ----.. .. ... ... ... ... .. .. -.. -.. Drainage Study lonis Lots 21 and 22 Runoff is collected via curb inlets and piped to a modular wetland (Modular Wetland 3) for water quality treatment and then routed to a separate concrete storage vault (Storage Vault 3). The vault has a volume of approximately 7,300 cubic feet at the weir height, with a weir 4" above the vault bottom and a 1" orifice. Drainage Area 6 is approximately 1. 7-acres and includes the southern portion of the project site, including a portion of the main building, southwestern parking area and driveway, and surrounding landscape. Runoff is collected via roof inlets and curb inlets and piped to a modular wetland (Modular Wetland 4) for water quality treatment and then routed to a separate concrete storage vault (Storage Vault 4). The vault has a volume of approximately 7,340 cubic feet at the weir height, with a weir 4" above the vault bottom and a 1" orifice . Refer to Appendix C for an exhibit detailing the proposed condition . 3 Section 2 Study Objectives The specific objectives of this study are as follows: Drainage Study lonis Lots 21 and 22 • Quantify 100-year 6-hour peak flow rates under existing and proposed conditions to all discharge points; • Develop measures to mitigate any increase in peak flow associated with proposed improvements during the 100-year 6-hour storm event; • Demonstrate the proposed improvements will not increase the potential for erosion on the project site or downstream area. • Demonstrate that the tributary area for the existing infiltration basin is reduced by the proposed improvements. 4 .. 11111 .. .. .. --.. ... ... 111111 .. .. .. .. ... ... ,,,, .. ... .., .. -.. - 1111 .. .. ""' .. - 1111 Section 3 Methodology 3.1 Hydrology Drainage Study lonis Lots 21 and 22 The Rational Method has been utilized to perform the hydrologic analyses. The following formula conforms to the hydrologic methodologies outlined in the County of San Diego Hydrology Manual (June 2003). Where, Q = Peak Discharge -(cfs) C = Runoff Coefficient I = Average Rainfall Intensity -(in/hr) A= Drainage Area -(acres) A weighted runoff coefficient has been calculated for the existing and proposed conditions per Section 3.1.2 and Table 3-1 of the County of San Diego Hydrology Manual. The tabulated impervious area chosen for the project site is 35% (natural) for the existing condition and 85% (commercial use) for the proposed condition. A conservative time of concentration of 5 minutes has been assumed for the project area under existing and proposed conditions. Intensity has been calculated per the IDF Curve in Figure 3-1 of the County of San Diego Hydrology Manual. 3.2 Hydraulics Bentley's Pond Pack has been used to model peak flows from the project as they are mitigated by the proposed detention vaults. Hydrographs generated by Rick Engineering Company's RatHydro software have been routed through storage vaults modeled in Hydraflow Hydrographs. Refer to Appendix C for the modelling input and output. 5 Section 4 Results 4.1 Hydrologic Results Drainage Study lonis Lots 21 and 22 The table below summarizes the hydrologic results under existing and proposed conditions.

Discharge Point 2 -The peak flow rate at discharge location 2 is reduced by biofiltration basins designed with flood control capabilities or modular wetlands with concrete storage vaults. Discharge Point 3 -The peak flow rate at discharge location 3 is reduced by modular wetlands with concrete storage vaults. The design for the biofiltration basins and outlet structures are summarized in Table 4-2 and Table 4-3 below. Calculations are included in Appendix C.

Any increase in peak flow will be mitigated by biofiltration basins with flood control aspects or modular wetlands with concrete storage vaults, reducing the proposed peak flow below the existing condition. These biofiltration BMPs also provide hydromodification mitigation which is discussed in more detail within the SWQMP, which was prepared by Michael Baker International in June 2021. Since all proposed peak flow was reduced to below that of the existing condition, the result of the proposed improvements will not increase flood risk to downstream properties, storm water facilities, or receiving water bodies. No risk of erosion is associated with the ultimate condition. This project will not discharge, dredge, or fill material into any Water of The United States, thus the project is not required to obtain a Section 401 certification or Section 404 permit from the State or U.S. Army Corps of Engineers. 8 Section 6 Declaration of Responsible Charge Drainage Study lonis Lots 21 and 22 I, hereby declare that I am the Civil Engineer of work for this project, that I have exercised responsible charge over the design of the project as defined in Section 6703 of the Business and Professions Code, and that the design is consistent with current design. I understand that the check of project drawings and specifications by the City of San Diego is confined to a review only and does not relieve me, as Engineer of Work, of my responsibilities for the project design.

USDA United States ~ Department of Agriculture NRCS Natural Resources Conservation Service A product of the National Cooperative Soil Survey, a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local participants Custom Soil Resource Report for San Diego County Area, California lonis Lots 21 and 22 June 21 , 2021 Preface Soil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov. usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/? cid=nrcs142p2_053951 ). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

Warning: Soil Map may not be valid at this scale. Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale. Please rely on the bar scale on each map sheet for map measurements. Source of Map: Natural Resources Conservation Service Web Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857) Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required.

Soil Survey Area: San Diego County Area, California Survey Area Data: Version 15, May 27, 2020 Soil map units are labeled (as space allows) for map scales 1 :50,000 or larger. Date(s) aerial images were photographed: Jan 23, 2020-Feb 13,2020 The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. 8 100.0% 100.0% -.. .. -... -----.. --... ------... -.. .. -.. ... .. ... ... -.. --- Custom Soil Resource Report An identifying symbol precedes the map unit name in the map unit descriptions . Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas . These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example . An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example . Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example . 9 Custom Soil Resource Report San Diego County Area, California CIE2-Cieneba coarse sandy loam, 15 to 30 percent slopes, eroded Map Unit Setting National map unit symbol: hb9r Elevation: 500 to 4,000 feet Mean annual precipitation: 12 to 35 inches Mean annual air temperature: 57 to 64 degrees F Frost-free period: 200 to 300 days Farmland classification: Not prime farmland Map Unit Composition Cieneba and similar soils: 85 percent Minor components: 10 percent Estimates are based on observations, descriptions, and transects of the mapunit.

These maps are included in the County Hydrology Manual (10, 50, and 100 yr maps induded in the Design and Procedure Manual). (2) Adjust 6 hr precipitation (if necessary) so that it is within the range of 45% to 65% of the 24 hr precipitation (not applicaple to Desert). (3) Plot 6 hr precipitation on the right side of the chart. (4) Draw a line through the point parallel to the plotted lines. (5) This line is the intensity-duration curve for the location being analyzed.
