FINDINGS
Recognized Environmental Condition (REC) is defined by the ASTM Standard Practice E1527-13 as the presence or likely presence of any hazardous substances or petroleum products in, on, or at a property: (1) due to release to the environment; (2) under conditions indicative of a release to the environment; or (3) under conditions that pose a material threat of a future release to the environment.
• AEI did not identify evidence of RECs during the course of this assessment.

Controlled Recognized Environmental Condition (CREC) is defined by the ASTM Standard Practice E1527-13 as a past release of hazardous substances or petroleum products that has been addressed to the satisfaction of the applicable regulatory authority, with hazardous substances or petroleum products allowed to remain in place subject to the implementation of required controls.
• AEI did not identify evidence of CRECs during the course of this assessment.

Historical Recognized Environmental Condition (HREC) is defined by the ASTM Standard Practice E1527-13 as a past release of any hazardous substances or petroleum products that has occurred in connection with the property and has been addressed to the satisfaction of the applicable regulatory authority or meeting unrestricted use criteria established by a regulatory authority, without subjecting the property to any required controls. • AEI did not identify evidence of HRECs during the course of this assessment.

Other Environmental Considerations (OEC) warrant discussion, but do not qualify as RECs as defined by the ASTM Standard Practice E1527-13. These include, but are not limited to, de minimis conditions and/or environmental considerations such as the presence of ACMs, LBP, radon, mold, and lead in drinking water, which can affect the liabilities and financial obligations of the client, the health and safety of site occupants, and the value and marketability of the subject property.
• AEI did not identify evidence of Other Environmental Considerations during the course of this assessment.

CONCLUSIONS, OPINIONS, AND RECOMMENDATIONS
We have performed a Phase I ESA in conformance with the scope and limitations of ASTM Standard Practice E1527-13 and the EPA Standards and Practices for All Appropriate Inquiries (40 CFR Part 312) of 26501-26505 Aliso Creek Road, Aliso Viejo, Orange County, California, the subject property. Any exceptions to, or deletions from, this practice are described in Sections 1.4,

1.5, and 1.6 of this report.

AEI did not identify evidence of RECs or CRECs in connection with the subject property during the course of this assessment. AEI recommends no further investigation for the subject property at this time.

This environmental assessment report is intended for the sole us of the California Bank and Trust to assist in its internal ‘due diligence’ process pertaining to the property which is the subject of the report. No republication, copying or distribution of any part of this report is authorized without the written consent of the California Bank and Trust and the company preparing the report. The California Bank and Trust makes no representation as to the accuracy or completeness of any information or conclusions in the report, including without limitation, whether the report complies with regulation governing All Appropriate Inquiries or the qualifications of the preparer of the report. Unless otherwise indicated by California Bank and Trust, no person or party, other than the California Bank and Trust, are entitled to rely on the report.

1.0 INTRODUCTION
This report documents the methods and findings of the Phase I ESA performed in conformance with AEI's contract and scope and limitations of ASTM Standard Practice E1527-13 and the EPA Standards and Practices for All Appropriate Inquiries (40 CFR Part 312) for the property located at 26501-26505 Aliso Creek Road, Aliso Viejo, Orange County, California (Appendix A: Figures and Appendix B: Property Photographs).

1.1 SCOPE OF WORK
The purpose of the Phase I ESA is to assist the client in identifying potential RECs, in accordance with ASTM E1527-13, associated with the presence of any hazardous substances or petroleum products, their use, storage, and disposal at and in the vicinity of the subject property. Property assessment activities focused on: 1) a review of federal, state, tribal, and local databases that identify and describe underground fuel tank sites, leaking underground fuel tank sites, hazardous waste generation sites, and hazardous waste storage and disposal facility sites within the ASTM approximate minimum search distance; 2) a property and surrounding site reconnaissance, and interviews with the past and present owners and current occupants and operators to identify potential environmental contamination; and 3) a review of historical sources to help ascertain previous land use at the site and in the surrounding area.

1.2 ADDITIONAL SERVICES
Other Environmental Considerations such as ACMs, LBP, lead in drinking water, radon, mold, and wetlands can result in business environmental risks for property owners which may disrupt current or planned operations or cash flow and are generally beyond the scope of a Phase I assessment as defined by ASTM E1527-13. Based upon the agreed-on scope of services this ESA did not include subsurface or other invasive assessments, business environmental risks, or other services not specifically identified and discussed herein.

1.3 SIGNIFICANT ASSUMPTIONS
The following assumptions are made by AEI in this report. AEI relied on information derived from secondary sources including governmental agencies, the client, designated representatives of the client, property contact, property owner, property owner representatives, computer databases, and personal interviews. AEI has reviewed and evaluated the thoroughness and reliability of the information derived from secondary sources including government agencies, the client, designated representatives of the client, property contact, property owner, property owner representatives, computer databases, or personal interviews. It appears that all information obtained from outside sources and reviewed for this assessment is thorough and reliable.

However, AEI cannot guarantee the thoroughness or reliability of this information.

Groundwater flow, unless otherwise specified by on-site well data or well data from the subject property or nearby sites, is inferred from contour information depicted on the USGS topographic maps. AEI assumes the property has been correctly and accurately identified by the client, designated representative of the client, property contact, property owner, and property owner's representatives.

1.4 LIMITATIONS
Property conditions, as well as local, state, tribal, and federal regulations can change significantly over time. Therefore, the recommendations and conclusions presented as a result of this assessment apply strictly to the environmental regulations and property conditions existing at the time the assessment was performed. Available information has been analyzed using currently accepted assessment techniques and it is believed that the inferences made are reasonably representative of the property. AEI makes no warranty, expressed or implied, except that the services have been performed in accordance with generally accepted environmental property assessment practices applicable at the time and location of the assessment.

Considerations identified by ASTM as beyond the scope of a Phase I ESA that may affect business environmental risk at a given property include the following: ACMs, radon, LBP, lead in drinking water, wetlands, regulatory compliance, cultural and historical resources, industrial hygiene, health and safety, ecological resources, endangered species, indoor air quality, mold, and high voltage lines. These environmental issues or conditions may warrant assessment based on the type of the property transaction; however, they are considered non-scope issues under ASTM Standard Practice E1527-13.

If requested by the client, these non-scope issues are discussed herein. Otherwise, the purpose of this assessment is solely to satisfy one of the requirements for qualification of the innocent landowner defense, contiguous property owner or bona fide prospective purchaser under CERCLA. ASTM Standard Practice E1527-13 and the United States EPA Standards and Practices for All Appropriate Inquiries (40 CFR Part 312) constitute the "all appropriate inquiry into the previous ownership and uses of the property consistent with good commercial or customary practice" as defined in:

1. 42 U.S.C. § 9601(35)(B), referenced in the ASTM Standard Practice E1527-13.

2. Sections 101(35)(B) (ii) and (iii) of CERCLA and referenced in the EPA Standards and Practices for All Appropriate Inquiries (40 CFR Part 312).

3. 42 U.S.C. § 9601(40) and 42 U.S.C. § 9607(q).

The Phase I ESA is not, and should not be construed as, a warranty or guarantee about the presence or absence of environmental contaminants that may affect the property. Neither is the assessment intended to assure clear title to the property in question. The sole purpose of assessment into property title records is to ascertain a historical basis of prior land use.

All findings, conclusions, and recommendations stated in this report are based upon facts, circumstances, and industry-accepted procedures for such services as they existed at the time this report was prepared (i.e., federal, state, and local laws, rules, regulations, market conditions, economic conditions, political climate, and other applicable matters). All findings, conclusions, and recommendations stated in this report are based on the data and information provided, current subject property use, and observations and conditions that existed on the date and time of the property reconnaissance.

Responses received from local, state, or federal agencies or other secondary sources of information after the issuance of this report may change certain facts, findings, conclusions, or circumstances to the report. A change in any fact, circumstance, or industry-accepted procedure upon which this report was based may adversely affect the findings, conclusions, and recommendations expressed in this report.

AEI's limited radon screening, if included, is intended to provide a preliminary screening to evaluate the potential presence of elevated radon concentrations at the site. The proposed scope is not intended to define the full extent of the presence of radon at the subject property. As such, the results should be used for lending purposes only. The recommendations and conclusions presented as a result of the limited preliminary radon screening apply strictly to the property conditions existing at the time the sampling was performed. The sample analytical results are only valid for the time, place, and condition of the site at the time of collection and AEI does not warrant that the results will be repeatable or are representative of past or future conditions.

1.5 LIMITING CONDITIONS/DEVIATIONS
The performance of this Phase I ESA was limited by the following:
• While additional assessments may have been conducted on the subject property, these documents must be provided for AEI's review in order for the information to be summarized/included in this Phase I ESA. Please refer to Section 6.3 for a summary of previous reports and other documentation provided to AEI during this assessment. • The User did not complete the ASTM User Questionnaire or provide the User information to AEI. AEI assumes that qualification for the LLPs is being established by the User in documentation outside of this assessment.

1.6 DATA FAILURE AND DATA GAPS
According to ASTM E1527-13, data gaps occur when the Environmental Professional is unable to obtain information required by the Standard, despite good faith efforts to gather such information. Pursuant to ASTM E1527-13, only significant data gaps, defined as those that affect the ability of the Environmental Professional to identify RECs, need to be documented.

Data failure is one type of data gap. According to ASTM E1527-13, data failure occurs when all of the standard historical sources that are reasonably ascertainable and likely to be useful have been reviewed and yet the objectives have not been met. Pursuant to ASTM E1527-13, historical sources are required to document property use back to the property's first developed use or back to 1940, whichever is earlier, or periods of five years or greater.

1.6.1 DATA FAILURE
AEI did not identify evidence of data failure during the course of this assessment.

1.6.2 SIGNIFICANT DATA GAPS
AEI did not identify significant data gaps which affected our ability to identify RECs.

5.0 REGULATORY DATABASE RECORDS REVIEW
AEI contracted EDR to conduct a search of publicly available information from federal, state, tribal, and local databases containing known and suspected sites of environmental contamination and sites of potential environmental significance. Data gathered during the current regulatory database search is compiled by EDR into one regulatory database report. Location information for listed sites is designated using geocoded information provided by federal, state, or local agencies and commonly used mapping databases with the exception of "Orphan" sites. Due to poor or inadequate address information, Orphan sites are identified but not geocoded/mapped by EDR, rather, information is provided based upon vicinity zip codes, city name, and state.

The number of listed sites identified within the approximate minimum search distance from the federal and state environmental records database listings specified in ASTM Standard E1527-13 is summarized in Section 5.1, along with the total number of Orphan sites. A copy of the regulatory database report, which includes detailed descriptions of the databases noted below, is included in Appendix C of this report.

In determining if a listed site is a potential environmental concern to the subject property, AEI generally applies the following criteria to classify the site as lower potential environmental concern: 1) the site only holds an operating permit (which does not imply a release), 2) the site's distance from, and/or topographic position relative to, the subject property, and/or 3) the site has recently been granted "No Further Action" by the appropriate regulatory agency.

Regulatory database listings associated with the subject property, adjoining site(s) and/or nearby sites of concern that were determined to warrant additional discussion are identified and further discussed in Section 5.1.

8.0 NON-ASTM SERVICES

8.1 ASBESTOS-CONTAINING BUILDING MATERIALS
Asbestos is the name for a group of naturally occurring silicate minerals that can be separated into fibers. The fibers are strong, durable, and resistant to heat and fire. They are also long, thin and flexible, so they can even be woven into cloth. Because of these qualities, asbestos has been used in thousands of consumer, industrial, maritime, automotive, scientific and building products. During the 20th century, some 30 million tons of asbestos have been used in industrial sites, homes, schools, shipyards and commercial buildings in the United States. Commercial use of ACM began in the early 1900s and peaked in the period between 1940 and into the 1970s.

Common ACMs include pipe-covering, insulating cement, insulating block, refractory and boiler insulation materials, transite board, fireproofing spray, joint compound, vinyl floor tile, ceiling tile, mastics, roofing products, and duct insulation for HVAC applications. Inhalation of asbestos fibers can result in deleterious health effects.

The potential for ACM was evaluated based the United States EPA Guidance Document:

Managing Asbestos in Place - A Building Owner's Guide to Operations and Maintenance Programs for Asbestos-Containing Materials (the Green Book). In 1973 the NESHAPS banned the use of most spray-applied surfacing ACM, specifically asbestos containing spray-on fireproofing and insulation. Subsequent revisions to this regulation in 1975 and 1978 effectively eliminated the use of friable pre-molded pipe, boiler, turbine, and duct insulation; and the spray application of friable asbestos-containing materials for all uses in buildings. In 1989 the EPA issued regulations to ban some asbestos-containing products and phase out most others over a multi-year period.

The "Ban and Phase-Down" rule was challenged in court and the regulation remanded to the agency. As a result, any asbestos-containing products then "in commerce" would not be banned.

Those not in commerce would be banned. Those materials "banned" could not be sold. It did not affect such materials already installed, or in use. Most US firms voluntarily ceased production of asbestos containing building materials not covered by the aforementioned Federal bans by the mid-1980s. In 1994, the OSHA determined that employers and building owners are required to treat installed thermal system installation and sprayed on and troweled-on surfacing materials, as well as vinyl or asphalt flooring material, as ACM in buildings constructed no later than 1980 until tested by laboratory analysis to prove otherwise.

The information below is for general informational purposes only and does not constitute an asbestos survey. In addition, the information is not intended to comply with federal, state or local regulations in regards to ACM.

Although the cutoff date of 1981 referenced in the OSHA regulations is generally accepted for estimating the likelihood that certain building materials may contain asbestos, building materials manufactured after 1981, while not expected to, may still contain asbestos. Typical materials that are known to still be manufactured with asbestos include but are not limited to: asphalt roofing products and building caulking materials and adhesives. A limited list of typical suspect ACMs is included in the following table:

The observed suspect ACMs were in good condition and are not expected to pose a health and safety concern to the occupants of the subject property at this time. In the event that building renovation or demolition activities are planned, a thorough asbestos survey is required in accordance with the EPA NESHAP 40 CFR Part 61 prior to demolition or renovation activities that may disturb ACMs.

8.2 LEAD-BASED PAINT
Lead-based paint (LBP) is defined as any paint, varnish, stain, or other applied coating that has ≥1 mg/cm² (5,000 μg/g or 5,000 ppm) or more of lead by federal guidelines; state and local definitions may differ from the federal definitions in amounts ranging from 0.5 mg/cm² to 2.0 mg/cm². Section 1017 of the Housing and Urban Development (HUD) Guidelines, Residential Lead-Based Paint Hazard Reduction Act of 1992, otherwise known as "Title X," defines a LBP hazard as "any condition that causes exposure to lead that would result in adverse human health effects" resulting from lead-contaminated dust, bare, lead-contaminated soil, and/or lead-contaminated paint that is deteriorated or present on accessible, friction, or impact surfaces.

Therefore, under Title X, intact LBP on most walls and ceilings would not be considered a "hazard," although the paint should be maintained and its condition monitored to ensure that it does not deteriorate and become a hazard. Additionally, Section 1018 of this law directed HUD and EPA to require the disclosure of known information on LBP and LBP hazards before the sale or lease of most housing built before 1978. Most private housing, public housing, or federally owned or subsidized housing is affected by this rule.

Under OSHA, lead-containing paint (LCP) is defined as any paint with any detectable amount of lead present in it. Therefore, all LBP is considered LCP. Conversely, LCP may not meet the criteria to be considered LBP in accordance with HUD guidelines or some states’ definition of LBP.

It is important to note that LCP may create a lead hazard when being removed. The condition of these materials must be monitored when they are being disturbed. In the event LCP is subject to abrading, sanding, torching, and/or cutting during demolition or renovation activities, there may be regulatory issues that must be addressed.

The information below is for general informational purposes only and does not constitute a lead hazard evaluation. In addition, the information is not intended to comply with federal, state, or local regulations in regards to LBP.

In buildings constructed after 1978, it is unlikely that LBP is present; however, some paints utilized after 1978 will be LCP under OSHA. Structures built prior to 1978 and especially prior to the 1960s should be expected to contain LBP.

Due to the age of the subject property building, it is unlikely that LBP is present; however, LCP may be present. Based on the good condition of the observed painted surfaces, potential LCP is not considered a significant environmental concern at this time.

8.3 RADON
Radon is a naturally-occurring, odorless, and invisible gas. Natural radon levels vary and are closely related to geologic formations. Radon may enter buildings through basement sumps or other openings.

The United States EPA has prepared a map to assist National, State, and local organizations to target their resources and to implement radon-resistant building codes. The map divides the country into three radon zones, with Zone 1 being those areas with the average predicted indoor radon concentration in residential dwellings exceeding the EPA Action Limit of 4.0 pCi/L. It is important to note that the EPA has found homes with elevated levels of radon in all three zones, and the EPA recommends site specific testing in order to determine radon levels at a specific location. However, the map does give a valuable indication of the propensity of radon gas accumulation in structures.

Radon sampling was not requested as part of this assessment. According to the US EPA, the radon zone level for the area is Zone 3, which has a predicted average indoor screening level less than 2 pCi/L, below the action level of 4 pCi/L set forth by the US EPA.

8.4 MOLD
Molds are simple microscopic organisms which can often be seen in the form of discoloration, frequently green, gray, white, brown, or black. When excessive moisture or water accumulates indoors, mold growth may occur, particularly if the moisture problem remains undiscovered or unaddressed. As such, interior areas of buildings characterized by poor ventilation and high humidity are the most common locations of mold growth. Building materials, including drywall, wallpaper, baseboards, wood framing, insulation, and carpeting, often play host to such growth.

Mold spores primarily cause health problems through the inhalation of spores or the toxins they emit when they are present in large numbers. This can occur when there is active mold growth within places where people live or work.

Mold, if present, may or may not visually manifest itself. Neither the individual completing this inspection, nor AEI has any liability for the identification of mold-related concerns except as defined in applicable industry standards. In short, this Phase I ESA should not be construed as a mold survey or inspection.

Project No. 460782
May 4, 2022

Page 31 ends

This activity was not designed to discover all areas which may be affected by mold growth on the subject property. Rather, it is intended to give the client an indication if significant (based on observed areas) mold growth is present at the subject property. Potential areas of mold growth, such as in pipe chases, HVAC systems, and behind enclosed walls and ceilings, were not observed as part of this limited assessment.

AEI observed interior areas of the subject property building to identify the potential presence of mold. AEI did not note obvious visual or olfactory indications of the presence of mold, nor did AEI observe obvious indications of significant water damage. As such, no bulk sampling of suspect surfaces was conducted as part of this assessment and no additional action with respect to suspect mold appears to be warranted at this time.

2.2 Post Development Drainage Characteristics
Proposed grading of the site will match existing grading in the parking field area. Portions of the proposed buildings extend into the existing slope adjacent to Enterprise and will require retaining walls to retain the existing grade up to Enterprise. Retaining wall heights are anticipated to range from 3 feet to 35 feet based on the current site plan.

The proposed improvements feature courtyards between the blocks of apartment buildings that face the roadside slope. The drainage conditions of these courtyards will have a high importance in establishing the grading concept for the site. Runoff within these courtyards will be designed to freely flow away from the structures toward the roadside slope and continue down and around the complex before it ultimately discharges to the center’s existing storm drain system. This path of travel for runoff will be critical to ensure the flood protection of the structures in this area of the project.

The proposed project is initially anticipated to be an export site due to the large cuts into the roadside slope, water quality detention system, site utilities, pavement section, building and parking structure footings, and topsoil and planting requirements.

The small portion of the existing parking field southeast beyond the limits of the project improvements will share a storm drain inlet and will co-mingle with project runoff in DMA-C.

This off-site run-on is captured and treated by the project BMPs, however it creates a discrepancy between the project improvement area (4.06 acres) used in the project description, and the Drainage Management Areas (4.17 acres) used for stormwater calculations.

2.3 Property Ownership/Management

Section 3 Site & Watershed Characterization

3.1 Site Conditions

3.1.1 Existing Site Conditions
The site features a large slope between Enterprise and the parking field. At the intersection of Enterprise and Town Center, the parking field is roughly 4 feet lower than the public roadway. As Enterprise travels north, the roadway has an upward slope of approximately 7%, resulting in a 50 foot difference in elevation from the roadway down to the parking field at the northerly end of the project.

Existing grades within the parking field are relatively flat with 1-2 feet of relief from one side of the site to the other.

The existing drainage pattern consists of overland flow to several drop inlets scattered across the parking field. The drop inlets connect to an onsite storm drain system that flows south and exits the property to through a 36” RCP connection to a County owned 90” RCP within Enterprise near its intersection with Aliso Creek Road.

3.1.2 Infiltration-Related Characteristics
Storm water infiltration into the subsurface soils is not considered feasible due to the presence of clayey subgrade soils and diatomaceous siltstone bedrock.

3.1.2.1 Hydrogeologic Conditions
Groundwater was encountered in the form of seepage zones at approximate elevations of 320 to 328 feet above MSL (mean sea level), which is roughly 20 feet below the existing asphalt parking lot.

Refer to the Geotechnical Report in the Appendix.

3.1.2.2 Soil and Geologic Infiltration Characteristics

3.2 Proposed Site Development Activities

3.2.1 Overview of Site Development Activities
Proposed grading of the site will match existing grading in the parking field area. Portions of the proposed buildings extend into the existing slope adjacent to Enterprise and will require retaining walls to retain the existing grade up to Enterprise. Retaining wall heights are anticipated to range from 3 feet to 35 feet based on the current site plan.

3.2.2 Project Attributes Influencing Stormwater Management As noted above in Section 3.2.1, the subject site discharges to the to the private onsite storm drain network withing the shopping center. The proposed storm drain system for the apartment complex will be designed to convey runoff, unimpeded, to the existing private storm drain network. The 85th percentile (water quality) storm events will be captured by the on-site, underground detention system (see water quality section below), while larger storm event peak flows will bypass the detention system and directly discharge to the downstream storm drain.

3.2.3 Effects on Infiltration and Harvest and Use Feasibility Storm water infiltration into the subsurface soils is not considered feasible due to the presence of clayey subgrade soils and diatomaceous siltstone bedrock. Harvest and use is also not feasible due to the lack of necessary pervious area.

3.3 Receiving Waterbodies
The project site is within the Aliso Creek watershed. The site drains into an existing 15” which discharges into Aliso Creek which ultimately discharges into the Pacific Ocean.

3.5 Hydrologic Conditions of Concern
Does a hydrologic condition of concern exist for this project? Yes, due to the drainage being received by Aliso Creek which is an earthen channel.

No – An HCOC does not exist for this receiving water because:

Project discharges directly to a protected conveyance (bed and bank are concrete lined the entire way from the point(s) of discharge to a receiving lake, reservoir, embayment, or the Ocean
Project discharges directly to storm drains which discharge directly to a reservoir, lake, embayment, ocean or protected conveyance (as described above) The project discharges to an area identified in the WMAA as exempt from hydromodification concerns
Yes – An HCOC does exist for this receiving water because none of the above are applicable.

Repeat this checklist for each different receiving water to which the project would discharge.

3.6 Critical Course Sediment Yield Areas
The potential for critical coarse sediment does not apply per map N.8 in the TGD. Sediment is not anticipated to be a contributing factor to discharge from the developed condition and storm drain network.

Section 4 Site Plan and Drainage Plan

4.1 Drainage Management Area Delineation
Proposed grading of the site will match existing grading in the parking field area. Portions of the proposed buildings extend into the existing slope adjacent to Enterprise and will require retaining walls to retain the existing grade up to Enterprise. Retaining wall heights are anticipated to range from 3 feet to 35 feet based on the current site plan.

DMA-A: This area, which is 0.96 acres, will capture drainage in an underground storm drainage system and flow into an underground detention system. The underground detention system will discharge to a Modular Wetland System (or equivalent linear treatment device) with an internal high flow bypass for flows exceeding the required treatment rate, then discharge to the downstream storm drain system.

DMA-B: This area, which is 2.89 acres, will capture drainage in an underground storm drainage system and then it will flow into an underground detention system. A weir structure will divert low flows equivalent to the required treatment volume or treatment flow rate from the underground detention system into a Modular Wetland System (or equivalent linear treatment device) and then discharge to the downstream storm drain system. Large storm events exceeding the water quality treatment requirements will overtop the weir, bypass the treatment system, and discharge to the downstream storm drain system.

Page 12 ends

DMA-C: This drainage area, which is 0.32 acres, consist of an ashpault parking area. The existing stormwater inlet and low spot of this drainage area is located where the proposed building will be.

Grades will be adjusted within the northern portion of DMA C to slope up and join the southeastern project frontage. The southern portion of DMA C will not be touched and will be considered off-site runon. A new catchbasin will be added to the new low spot of the parking field to maintain the existing drainage pattern of the parking field. DMA C will discharge to and be treated by the same undground detention system and Modular Wetland System (or equivalent linear treatment device) as DMA B.

4.2 Overall Site Design BMPs
The project site will capture drainage in an underground storm drainage system and then it will flow into an underground detention system. Low flows equivalent to the required treatment volume or treatment flow rate from the underground detention system will then be conveyed into a Modular Wetland System (or equivalent linear treatment device) which will drain down within 48 hours of the storm event and then exit into the existing storm drain system. 1106

4.3 DMA Characteristics and Site Design BMPs

4.3.1 DMA A - This area, which is 0.96 acres, will capture drainage in an underground storm drainage system and flow into an underground detention system. The underground detention system will discharge to a Modular Wetland System (or equivalent linear treatment device) with an internal high flow bypass for flows exceeding the required treatment rate, then discharge to the downstream storm drain system.

4.3.2 DMA B – This area, which is 2.89 acres, will capture drainage in an underground storm drainage system and then it will flow into an underground detention system. A weir structure will divert low flows equivalent to the required treatment volume or treatment flow rate from the underground detention system into a Modular Wetland System (or equivalent linear treatment device) and then discharge to the downstream storm drain system. Large storm events exceeding the water quality treatment requirements will overtop the weir, bypass the treatment system, and discharge to the downstream storm drain system.

4.3.3 DMA C – This drainage area, which is 0.32 acres, consist of an ashpault parking area. The existing stormwater inlet and low spot of this drainage area is located where the proposed building will be. Grades will be adjusted within the northern portion of DMA C to slope up and join the southeastern project frontage. The southern portion of DMA C will not be touched and will be considered off-site runon. A new catchbasin will be added to the new low spot of the parking field to maintain the existing drainage pattern of the parking field. DMA C will discharge to and be treated by the same undground detention system and Modular Wetland System (or equivalent linear treatment device) as DMA B.

Section 5 Low Impact Development BMPs

5.1 LID BMPs for DMA-A
DMA-A, which is 0.96 acres, will capture drainage in an underground storm drainage system and then it will flow into an underground detention system. Low flows equivalent to the required treatment volume or treatment flow rate from the underground detention system will discharge into a Modular Wetland System (or equivalent linear treatment device) and then exit into the existing storm drain system.

5.1.1 Hydrologic Source Controls for DMA-A
The full design capture volume is being treated by the LID BMP’s, no hydrologic source controls are proposed.

5.1.2 Structural LID BMP for DMA-A
The BMP used in the proposed project is a Modular Wetland System which is a linear stormwater bioretention device that treats the flow horizontally. This allows for a smaller footprint, higher treatment capacity, and design versatility.

The Modular Wetland System BMP has been designed to treat the calculated DCV of 3,073 cf for area DMA-A.

5.2 LID BMPs for DMA-B + DMA-C
Runoff from DMA-B and DMA-C will be captured in an underground storm drainage system and then will flow into an underground detention system. Low flows equivalent to the required treatment volume or treatment flow rate from the underground detention system will then be conveyed into a Modular Wetland System (or equivalent linear treatment device) and then exit into the existing storm drain system.

5.2.1 Hydrologic Source Controls for DMA-B + DMA-C
The full design capture volume is being treated by the LID BMP’s, no hydrologic source controls are proposed.

5.2.2 Structural LID BMP for DMA-B + DMA-C
The BMP used in the proposed project is a Modular Wetland System which is a linear stormwater bioretention device that treats the flow horizontally. This allows for a smaller footprint, higher treatment capacity, and design versatility.

The Modular Wetland System BMP has been designed to treat the calculated DCV of 10,382 cf for the combined area of DMA-B and DMA-C.

5.3 Summary of LID BMPs
In summary, the two Modular Wetland Systems will treat the calculated DCV for DMA-A and the combined area of DMA-B and DMA-C. The flow will then be discharged into the existing storm drain system and ultimately into the Pacific Ocean.

Section 6 Hydromodification BMPs

6.1 Points of Compliance
The point of compliance is the existing storm drain system within the existing shopping center. The project connects two existing storm drains (15” and 24”) as shown on the WQMP map which combine within the shopping center storm drain network before discharging to the public storm drain within Enterprise.

6.2 Pre-Development (Natural) Conditions
The site features a large slope between Enterprise and the parking field. At the intersection of Enterprise and Town Center, the parking field is roughly 4 feet lower than the public roadway. As Enterprise travels north, the roadway has an upward slope of approximately 7%, resulting in a 50 foot difference in elevation from the roadway down to the parking field at the northerly end of the project.

Existing grades within the parking field are relatively flat with 1-2 feet of relief from one side of the site to the other.

6.3 Post-Development Conditions and Hydromodification BMPs Proposed grading of the site will match existing grading in the parking field area. Portions of the proposed buildings extend into the existing slope adjacent to Enterprise and will require retaining walls to retain the existing grade up to Enterprise.

The project includes two underground detention systems, one within the parking field and one below an outdoor courtyard, that will mitigate peak flows to satisfy the hydromodification requirements. 1113

AvalonBay Communities Section 6

Page 20 ends

6.4 Measures for Avoidance of Critical Coarse Sediment Yield Areas
The potential for critical coarse sediment does not apply per map N.8 in the TGD. Sediment is not anticipated to be a contributing factor to discharge from the developed condition and storm drain network.

6.5 Hydrologic Modeling and Hydromodification Compliance The proposed underground detention systems have been sized for hydromodification compliance and limit the proposed 10-year site discharge rate to the existing natural condition 2-year site discharge rate. See the South Orange County Hydrology Model (SOHM) in the Appendix for calculations.

Subject: Preliminary Geotechnical Due Diligence Study, Proposed Commons Mixed-Use Apartment Development, City of Aliso Viejo, California

INTRODUCTION
At your request, NMG Geotechnical, Inc. (NMG) has prepared this preliminary geotechnical due diligence report for the proposed Commons project located northwest of the intersection of Aliso Creek Road and Enterprise in the city of Aliso Viejo. Our summary is based on review of available geotechnical reports and maps provided by you and the City of Aliso Viejo, review of historic aerial photographs and topographic maps; a site reconnaissance; our knowledge of geological conditions and constraints in the region; our experience during design, grading and construction of the Summit Business Park; and our experience with similar residential developments.

SITE LOCATION AND DESCRIPTION
The approximately 4.1-acre site is located northwest of the intersection of Aliso Creek Road and Enterprise in the city of Aliso Viejo, California. The site currently consists of an asphalt surface parking lot with planter medians and a 2H:1V slope that ascends up to 45 feet to Enterprise. The elevation across the asphalt parking lot is fairly flat, ranging from approximately 348 to 351 feet above mean sea level (msl).

The northwestern portion of the site consists of a 2H:1V buttress slope that ascends approximately 5 to 45 feet to Enterprise. We understand this compacted buttress fill slope was constructed with a subdrain system with subdrain outlets that extend to the slope face; some of these outlets were observed during our recent site reconnaissance. The fill material exposed in the slope and planters in the parking lot was observed to be white diatomaceous silt with small siltstone fragments. The asphalt surface and concrete V-ditches/curbs appear to be in moderately good condition, with some linear cracks throughout, generally consistent with aging improvements. ~ ~~~hnical, Inc.

SITE HISTORY
Based on our knowledge of the development in Aliso Viejo, the site was mass graded in the early 1990s by the Mission Viejo Company under the geotechnical observation and testing of The Earth Technology Corporation (Earth Tech), who also performed the initial investigation during the design stages of the site. We have not been able to obtain copies of these reports through requests from the City of Aliso Viejo.

Based on review of historic aerial photographs dating to 1946 and topographic maps dating to 1949, the site originally consisted of gentle hillside terrain ranging from 340 to 400 feet above msl.

The site sloped to the north to an incised channel in the location of the current State Route 73 Toll Road (SR 73). Historically, this region was used for dry farming and cattle grazing until the late 1980s when the Mission Viejo Company started development. The northeastern portion of the site was mass graded between 1988 and 1992, and included construction of Aliso Creek Road. By 1995, the entire site was graded to essentially its current condition, which included grading of the abutting slope and paving of Enterprise from Aliso Creek Road to the Town Center. Between 1996 and 1997, SR 73 was constructed and the adjacent commercial property to the northwest had been graded.

In 2006, Kleinfelder, Inc. (Kleinfelder) performed a feasibility study and provided design parameters specific to the subject site for a prior land use plan. The prior land use plan included two levels of subterranean development and retaining structures up to 55 feet high, essentially cutting out the buttress slope that ascends to Enterprise. Their study included three bucket-auger borings and slope stability analysis along the buttress slope. Their report did not include geotechnical borings logs, but provided a description of the fill and bedrock encountered and included cross-sections showing the bedrock layers dipping out of slope. They concluded that excavation into the buttress slope would render it unstable, and as such, they recommended a tieback anchor wall be designed and constructed (Kleinfelder, 2006).

PROPOSED DEVELOPMENT
Based on review of the yield study exhibits, the proposed mixed-use apartment development will be a wrap-style construction with up to six stories of retail and apartments around the perimeter, and a central eight-story parking structure. No subterranean structures are anticipated at the site.

The recreation area is anticipated to be constructed atop the parking structure. Although a grading study was not available for our review, the yield study exhibits show the buildings may encroach significantly into the adjacent buttress slope.

GEOLOGIC CONDITIONS
The subject site is located in the San Joaquin Hills within the coastal section of the Peninsular Range Province. This geomorphic province includes the Los Angeles Basin and has a long, active geologic history, including deep marine sedimentation followed by uplift and fluvial and marine erosion.

The subject site is underlain by artificial fill materials and interbedded diatomaceous siltstone/ claystone bedrock of the Monterey Formation. The bedrock was originally deposited within the Capistrano Embayment, which extended from San Clemente northward to the Santa Ana Mountains. During the Quaternary period, active faulting (associated with the San Andreas Fault system) subjected the embayment to compression and regional uplift. Also, during the Quaternary period, active streams channels cut canyons into the emergent bedrock. However, during past grading operations, the natural terrain was modified by cutting the ridges and filling canyon areas resulting in the current site configuration.

Geologic Units and Structure
We anticipate the northeast portion of the site and the buttress fill slope to consist of up to 20 to 40 feet of previously placed artificial fill primarily derived from bedrock of the Monterey Formation and placed under the observation and testing of Earth Tech (1995). Although we do not have the referenced report available, we have encountered the subject fill material during various phases of exploration for the adjacent Summit Business Park. Also, Kleinfelder encountered the fill during their site feasibility study (Kleinfelder, 2006) in two of their three borings. We anticipate the fill to consist of various mixtures of diatomaceous silt, elastic silt, clay, silty clay, and silty sand that is generally dry to moist, stiff, slightly to moderately plastic, and containing bedrock fragments.

The majority of the site may consist of sedimentary bedrock of the Monterey Formation, which also underlies the artificial fill. Within Aliso Viejo, the Monterey Formation consists predominately of light gray to light brown highly diatomaceous clayey siltstone, which is moist, stiff to hard, and locally highly fractured and jointed. The clayey siltstone is interbedded with abundant sheared clay beds and vitric tuff horizons. The material is locally highly laminated and well-bedded, and has been found to be compressible under significant loading. During their feasibility study, Kleinfelder (2006) encountered this bedrock in all three of their bucket-auger borings and described it as diatomaceous siltstone and shale deposits that are friable and relatively weak. They also encountered some very soft sheared clay beds every few feet within the siltstone and local lenses of volcanic ash, concretionary limestone, calcareous sandstone and thin sandstone beds.

The geologic structure within the area can be somewhat variable due to regional faulting and folding; however, bedding was identified and measured by Kleinfelder (2006) and found to dip 6 to 41 degrees consistently to the northeast. These dips correlate to an apparent dip of 8 to 39 degrees out of slope, for an adverse bedding condition within the slope adjacent to Enterprise.

Faulting
The site is not located within a fault-rupture hazard zone as defined by the Alquist-Priolo Special Studies Zones Act (California Geological Survey, 2018 and Hart and Bryant, 2007), and no evidence of active faulting was observed during this investigation or during rough grading operations. Also, based on mapping by the State (California Geological Survey, 2010), there are no active faults mapped at the site.

Using the USGS computer program (USGS, 2022) and the site coordinates of 33.5786 degrees north latitude and 117.7253 degrees west longitude, the controlling fault at the site is the San Joaquin Hills Blind Thrust Fault located 3.8 kilometers (≈ 2.4 miles) at depth below the site. The maximum moment magnitude for the Controlling Fault is 7.1 MW. The other faults noted that can produce strong ground shaking at the site include the Newport-Inglewood (Offshore), Elsinore Glen Ivy and Oceanside. Based on review of published maps, historic aerial photographs, and topographic maps, the potential for primary ground rupture due to an earthquake is considered very low.

Seismic Hazards
The primary seismic hazard at the subject site is ground shaking due to a future earthquake on a major regional active fault, such as the San Joaquin Hills Blind Thrust Fault mentioned above. The site is not located in a seismic hazard zone for liquefaction as mapped by the State, but the slope adjacent to the site that ascends to Enterprise is located in a seismic hazard zone for earthquake induced landslides (CDMG, 2001a), likely due to the regional geology. Figure 2 shows the subject site in relation to the seismic hazard zones mapped by the State. Development of the site by the Mission Viejo Company included slope stabilization measures to mitigate this potential hazard.

Groundwater
Groundwater was encountered in the form of seepage zones by Kleinfelder (2006) at approximate elevations of 320 to 328 feet above msl, which is roughly 20 feet below the existing asphalt parking lot. Groundwater was not encountered by NMG during our prior study for the adjacent business development (NMG, 1997). Historic high groundwater is in excess of 30 feet below ground surface (bgs) (CDMG, 2001b).

LABORATORY TESTING
The Kleinfelder feasibility study did not include tabulated laboratory test results, but it did indicate the soils are corrosive to concrete and metals, have moderate to very high expansion potential, and have low shear strengths with an average friction angle of 12 degrees and a cohesion of 100 pounds per square foot (psf) along bedding and 25 degrees and 500 psf cohesion for across bedding (Kleinfelder, 2006).

Prior laboratory testing by NMG (1997) for the adjacent business development indicated the compacted fill soils are generally comprised of silty clay with liquid limits of 66 to 81 percent and plasticity indices of 37 to 49 percent (USCS classification of CH). Sieve analysis of the same compacted fill soils shows 74 to 82 percent passing the No. 200 sieve and 37 to 47 percent passing the two-micron sieve. Expansion indices ranged from 73 to 111, falling in the medium to high expansion potential range and direct shear tests indicated ultimate friction angles of 30 to 47 degrees with 0 to 200 psf cohesion.

GEOTECHNICAL CONDITIONS/CONSTRAINTS
Based on the geotechnical data provided in the referenced reports (References) and review of published geologic maps/reports, the following conditions are anticipated. • Soil conditions across the site consist of artificial fill up to 20 to 40 feet thick within the buttress slope and the northeast portion of the site, and diatomaceous siltstone/claystone bedrock of the Monterey Formation exposed at existing grade for the southern and western portion of the existing parking lot.
• Overexcavation of both the bedrock and artificial fill materials should be anticipated, such that a minimum of 5 feet of new compacted fill underlies the building and footings. • Groundwater in the form of seepage was previously encountered at a depth of 20 feet below the existing parking lot grades. Other nuisance seepage may be encountered in heavily landscaped areas.
• Storm water infiltration into the subsurface soils is not considered feasible due to the presence of clayey subgrade soils and diatomaceous siltstone bedrock. • If grading/construction is proposed to encroach into the existing buttress slope, excavations into this slope may de-stabilize the slope and adversely impact Enterprise. Use of tie-back supported retaining structures and shoring should be anticipated during construction of the walls impacting this slope.
• The proposed parking structure and residential units may straddle a contact between siltstone bedrock and moderately deep artificial fill. Both of these earth units are considered compressible; thus, total and differential settlement under the heavy building load may be a significant constraint. Use of mat slab foundations, deep foundations and/or ground improvement (i.e., geopiers) may be required at the site. • Laboratory testing by NMG and others indicates the expansion index (EI) for soils at the site range from medium to very high.
• Based on chemical testing by Kleinfelder and on our experience at the adjacent business park, the sulfate exposure of the onsite soils is in the severe ("S4") range and may also be categorized as "severely corrosive" with respect to ferrous metals. • The site is not located in a seismic hazard zone for liquefaction, but the buttress slope along the western and northern border of the site is located in a seismic hazard zone for earthquakeinduced landslides. We anticipate that the prior grading of the buttress slope has adequately mitigated the potential for earthquake induced landslides. The most significant seismic hazard at the site is strong ground shaking due to an earthquake on a nearby active fault, such as the San Joaquin Hills Blind Thrust, Newport-Inglewood (Offshore), Elsinore Glen Ivy and Oceanside Faults.

EXPLORATION, PLANNING AND DESIGN RECOMMENDATIONS
The following presents a summary of our recommendations during the next phase of due diligence and future design stages.

1. A detailed subsurface exploration and laboratory testing program should be performed to verify the geotechnical conditions described herein in light of the proposed development.

2. Coordination with the design team, including the structural engineers for the parking structure foundation, residential building foundation, and the perimeter retaining structure will be important during analysis of the collected data.

3. Engineering analysis should be performed based on the subsurface exploration and should include settlement analysis, slope stability analysis, seismic design parameters, and foundation and wall design parameters. A geotechnical exploration and design report should be prepared documenting the geotechnical findings and site-specific conditions.

4. Future rough and precise grading plans should be reviewed and a report prepared to provide geotechnical parameters for design in accordance with the most recent requirements of the California Building Code (CBC).

5. The structural and foundation plans should be reviewed to confirm that the parameters used for design are in accordance with the recommendations of the design report.

6. The street improvement and utility plans should be reviewed and recommendations provided as needed.

If you have any questions regarding this preliminary due diligence study, please contact our office.
