The existing site consists of the hotel & spa, along with the associated parking structure. The Ritz-Carlton Residences project is in the southerly portion of the property and will encompass 3.95 acres of the total area. Adjacent land uses include other commercial development to the east, a golf course (Newport Beach Country Club) to the west, and residential property to the north and south. The site is zoned as visitor-serving commercial (see Zoning Map in Appendix 7). The site is located westerly of the intersection of Newport Center Drive and Santa Barbara Drive. A Vesting Tentative Tract Map showing the proposed layout is included in Appendix 1 of this report. A Vicinity Map is shown below. Figure 1 – Vicinity Map (not-to-scale) PA2021-296 PRELIMINARY HYDROLOGY REPORT December 2021 2 1112.008.02 The Ritz-Carlton Residences, Newport Beach 1.2 PROJECT DESCRIPTION The proposed project development will consist of demolition of one of the existing hotel buildings and existing parking structure, and construction of a new building and new adjacent parking structure at the southerly portion of the property. 1.3 PURPOSE OF THIS REPORT The purpose of this report is to provide hydrologic and hydraulics calculations and maps for existing and proposed conditions for the proposed project. 1.4 REFERENCES · Orange County Hydrology Manual · A.E.S. hydrologic software · City of Newport Beach GIS, As-Built Plans, Maps, and Atlas · Approved Final Hydrology Report for Newport Beach Marriot Renovation project (5/2021) PA2021-296 PRELIMINARY HYDROLOGY REPORT December 2021 3 1112.008.02 The Ritz-Carlton Residences, Newport Beach 2.0 EXISTING DRAINAGE 2.1 EXISTING TOPOGRAPHY The surface topography of the of the site generally slopes away from the buildings, with the westerly portion of the site generally draining toward the golf course, and the easterly portion of the site generally draining toward the roadways. The ground surface elevation near the northwesterly portion of the site is in the 179 to 180 feet range (NAVD88). The elevations in the vicinity of the main entrance to Santa Barbara Drive and Newport Center Drive at the northeasterly corner of the site are in the range of 180 to 183. The surface elevations at the mid-westerly area, adjacent to the golf course are in the 171 to 174 range. The elevations at the southerly portion of the site are in the 171 to173 range. 2.2 EXISTING DRAINAGE PATTERN The existing drainage pattern is generally from north to south, and toward the roadways to the east, and toward the golf course to the west. The intersection of Santa Barbara Drive and Newport Center Drive represent a high point in the adjacent roadways, with drainage on Santa Barbara Drive flowing northwesterly, and drainage on Newport Center Drive flowing southerly, following the easterly frontage from the property. The site receives no offsite drainage run-on. There are existing City of Newport Beach Storm Drain facilities that accept drainage from site frontage and onsite area drain systems. The storm drain atlas is included in Appendix 2 of this report. PA2021-296 PRELIMINARY HYDROLOGY REPORT December 2021 4 1112.008.02 The Ritz-Carlton Residences, Newport Beach 3.0 PROPOSED DRAINAGE The proposed development will include construction of a new building and parking structure. The proposed drainage is expected to generally mimic the existing drainage patterns. A portion (0.08 acres) of the southwestern area of the site will continue to drain westerly towards the golf course. A The new parking structure will drain easterly towards to Newport Center Drive and outlet through a curb drain. 4.0 HYDROLOGIC ANALYSIS 4.1 STORM FREQUENCY The 25-year and 100-year storm events have been evaluated be used for the existing and proposed conditions. 4.2 METHODOLOGY This study was prepared in conformance with the Orange County Hydrology Manual. Orange County Rational Method was used. A.E.S. Computer Software was utilized to compile the hydrologic data and to determine the peak discharges. The Soil Map is included in Appendix 3. The Existing Condition Hydrology Calculations are included in Appendix 4. The Proposed Condition Hydrology Calculations are included in Appendix 5. 5.0 FEMA The site is in Zone X (area of minimal flood hazard), as shown on FIRM Number 06059C0382K, effective 3/21/2019. Since the site is not within a Special Flood Hazard Area, as defined by FEMA, a CLOMR/LOMR will not be required. A copy of the Firmette is included in Appendix 6. 6.0 HYDRAULICS ANALYSIS Hydraulic computations have been provided for the 25-year and 100-year storm events. The WSPG hydraulics of the storm drain show that the HGL would stay below the existing ground. The hydraulic calculations are provided, and are included in Appendix 8 of this report. PA2021-296 PRELIMINARY HYDROLOGY REPORT December 2021 5 1112.008.02 The Ritz-Carlton Residences, Newport Beach 7.0 RESULTS AND CONCLUSIONS As discussed in this report, the proposed condition drainage patterns will generally mimic those of the existing condition, with the exception on sub-area E. The results show that the proposed condition flows do not exceed those of existing condition at any of the discharge locations. The existing and proposed drainage systems have capacities to provide drainage interception and conveyance for the proposed project. The hydrology maps (Appendices 4 and 5) show the Q25 and Q100 flow rates at the various discharge locations. The results are tabulated below.

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.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil 5 PA2021-296 scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil-landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and Custom Soil Resource Report 6 PA2021-296 identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately.

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. Custom Soil Resource Report 12 PA2021-296 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. 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.
