Subject: CPTED Inspection
John,
Today, 12/21/2011, I did the CPTED interior inspection for 15 Argonaut. The interior passes the CPTED inspection. I suggested that Ambry Genetics install a card reader for the first-floor electrical room which is adjacent to an exit door and roll-up door.
Tonight for the nighttime inspection of Ambry Genetics' exterior lighting, more than three-quarters of the wall-mounted exterior lighting and the parking lot lighting were not illuminating the building or parking lot. '
I will approve the TC of O for 15 Argonaut, but I would request that all exterior lighting and light poles be operational for another CPTED nighttime inspection either on Thursday, 12/22/2011, or next week.
Also, the exterior lighting and parking lot lighting at 31 Argonaut {S&K Towing) was not illuminating the building or parking lot this evening. I asked the employee Kevin to inform Craig about the lighting not illuminating the areas.
Thank you.

Hi Kevin,
Our standard procedure for plan check submittals is to have the customer fill out a variety of screening forms to determine what agency will need to review and approve the project.
In this case the customer answered yes to OCFA's screening from question No.l 11 Construction of a new bldg, new story, or increase the footprint .... 11 , which triggered the city to require OCFA approval. When scenarios like this happen where the answer is a yes but OCFA determines a review is not required, that's when we require something in writing waiving the review. Does that make sense?
Having said that, I can accept this email as OCFA's acknowledgment of the project and determination that an 11 architectural 11 review is not required.
Feel free to contact me if you have any questions. I'm here from 7:30 am to 12pm Monday - Friday, closed every other Friday.
Thank you,
Joanna

Hi Joanna,
If you look below to the email string, you'll see the OCFA's plan reviewers' comments on the subjedt of OCFA approval for issuance of a building permit for TI's to a B occupancy.
It looks like the plan submittal criteria form at the city would be sufficient for OCFA approval if all answers are 11 00 11 • If this won't do, can you give me a call at my office after lune~? I should be back in the office about 1:30 p.m. Thanks, Kevin I

The mezzanine is a Building call. We wouldn't h6ld up building permits. All we care about is the sprinkler T.I. plans to be submitted before they cover up the sprinkler pipe. -----Original Message-----

Ruben and Lynne,
The project is a TI for a B occupancy with no permits or hazardous materials over threshold amounts. A sprinkler plan will be required since they are constructing a mezzanine, but that should be it. What I'm confused about is the waiver for the city to allow this project to go forward. Have we (OCFA) done this in the past with a city building department to allow issuance of building permits? Any help would be appreciated.
Thanks, Kevin

Hi Mark,
I talked to Ted this morning regarding your resubmital and he had no issues with the changes you made to the plans; however, I do have to send the structural out for recheck.
It should be no more than 5 business days for review.
Regarding OCFA, you are correct in the fact that fire sprinklers are a separate submittal/permit; therefore it won't hold up your permit.
However, what we need in order to release the permit is an approval or waiver for the mezzanine and TI work. An email from Kevin waiving the review would be fine.
If you have any questions feel free to contact me.
Thank you,
Joanna

Hi JoannaOnce Ted has had an opportunity to review and approve the drawings I dropped off today please let me know.
You mentioned that one outstanding item was the OFCA approval. I spoke to Kevin at OFCA.
He wanted to make sure that the sprinklers were a deferred submittal, which we have indicated they are. He said in that case, he would defer to Ted as to issuance of a Permit and so OFCA review shouldn't hold up permit issuance.

TRANSMITTAL
Ambry Genetics is a testing lab with offices, currently residing in the City of Aliso Viejo.
As their operations have expanded, they require additional space. They have agreed to relocate to 15 Argonaut - also in the City of Aliso Viejo.
This new, larger facility, previously occupied by a memory chip company, had a similar business model which allows Arnbry a cost effective and relatively seamless expansion. It can also better accommodate their current and anticipated needs and it allows Ambry the chance to remain in the City of Aliso Viejo.
Re,·iewing City guidelines, we understand that Ambry is considered generally a dry lab with a minimal wet lab component.
Below is a description of the lab spaces of this project:
105 - R&D 2,954 s.f. (dry lab) - Use of small tubes and plates with micro-liter sized reactions. Various sequencing reactions and sample preps for next generation sequencing.
107 A,B,C- Test & Test Storage 1,092 s.f. & 491 s.f. (Future R&D dry lab)-for future expansion, no work going on in any of the 3 areas.
112-Sequence (dry lab) -1,053 s.f.- Samples are loaded onto various sequencing platforms using either sequencing plates or flow-cells (microscope slide sized chips).
Very little to no bench work required. This room will house the sequencing equipment that will run either overnight or over several days.
113- PCR (dry lab) - 434 s.f. This room will house all of our PCR machines. Samples will be placed in these machines in either plates or tubes and be left to cycle through various temperatures for a number of cycles. Again this is very little to no bench work required.
114A- Dcode (dry lab) - 451 s.f. Being left empty at the moment for future growth. 5618 E. CONANT STREET LONG BEACH, CA 90808 562.420. 1 035 1740

114B - QA (wet lab) - 449 s.f. This room is what I would consider "wet" because this is where we do all of our electrophoresis which uses buffered TAE solution mixed in with de-ionized water. Techs will load acrylamide gels with patient sample and let run for several hours as they gradually heat up and while constant voltage is being applied. 114C- Solutions (wet lab) - 329 s.f. - This is also what I would consider "wet" because this is where we use all of our chemicals in larger sized reactions. Usually in liters or in tens of liters. This is our reagent prep area.
The minimal amount of wet lab and the kinds and quantities of chemicals at this facility pose a minimal threat to public safety, yet Ambry is regulated by the following agencies:
The Federal agencies are CLIA = Clinical Laboratory Improvement Amendments and CAP = College of American Pathologists.
Federal License #

Executive Summary
Stantec Consulting Services, Inc. (Stantec) has performed a Phase II Environmental Site Assessment (ESA) of the property located at 35 15 Argonaut, Aliso Viejo, Orange County, California (the “Subject Property” Figure 1), on behalf of Brandywine Homes (the “Client”). The work was performed according to the requirements of the Master Services Agreement between Brandywine Homes and Stantec (the “MSA").
The Subject Property consists of approximately 4.35 acres of land associated with Assessor’s Parcel Numbers (APNs) 623-093-10 and 623-093-11, and the address of 15 Argonaut, Aliso Viejo, Orange County, California. According to records obtained through Environmental Data Resources (EDR), the Subject Property appears to have been vacant from at least the 1930s to 1980s and was commercially developed with one structure and asphalt parking lot by 1989 in its present-day configuration. The Subject Property building is currently vacant. The adjoining properties and vicinity are developed with commercial/light industrial businesses and residential properties. A Subject Property Location Map is provided as Figure 1. A Subject Property Vicinity Map illustrating the main features of the Subject Property and vicinity is provided as Figure 2.
The following potential vapor encroachment condition (pVEC) and recognized environmental condition (REC) were identified during the Phase I ESA completed for Subject Property dated July 14, 2025:
• A west-adjoining fuel station located at 23022 Aliso Creek Road is listed as a gasoline service station since 1996 that reportedly houses three active underground storage tanks (USTs) installed between 2004 and 2016. The USTs range from 10,000 to 20,000 gallons in size and contain diesel, regular and premium unleaded fuel. A minor spill of two gallons of fuel was reported in 2018 due to a vehicle overfill onto concrete. The spill was cleaned by onsite personnel. The site received permit-related violations between 2014 and 2016 which were returned to compliance. No releases are reported at the site. Given the proximity of the fuel station to the Subject Property, and no documented assessment of soil, soil vapor, or groundwater at the site, as well as inferred groundwater flow to the east, this site represented a potential VEC and was considered a REC for the Subject Property.
Accordingly, to evaluate the concern identified above, Stantec performed a Phase II Environmental Site Assessment to evaluate subsurface conditions at the Subject Property.
Phase II ESA Results
All work was conducted under the direct supervision of a State of California professional geologist.
Stantec provided the services of a field geologist to supervise and direct all on-site activities performed during this investigation, which included the following:
• Stantec obtained an Underground Service Alert (USA) ticket number prior to commencement of drilling activities. Additionally, Stantec subcontracted a private utility locator to clear all proposed boring locations.
1768
Phase II Environmental Site Assessment
Executive Summary
Project: 185806577 iii
• On August 26, 2025, Stantec personnel oversaw the advancement of three (3) soil vapor borings (SV-1 through SV-3) to 5-feet below ground surface (bgs) on the Subject Property. • On August 28, 2025, Stantec personnel oversaw soil vapor sampling of the newly-installed soil vapor probes at the Site. Soil vapor sampling was performed by A&R Laboratories (ARL), and analyzed on-site in a mobile laboratory. Soil boring SV-2 was submerged in water due to irrigation and no sample could be collected.
Soils encountered during this investigation generally consisted of silt and clay with sand to the maximum explored depth of 5.5 feet below ground surface (bgs). PID readings were measured at 0.0 parts per million by volume (ppmV) at all locations. No olfactory response, staining, or odors were observed in any borings advanced during this investigation.
Laboratory analytical test results from this assessment are attached as Appendix A. A summary of the analytical data from this assessment is provided below:
• Soil Vapor: There were no detections of any volatile organic compounds (VOCs) above their respective laboratory reporting limits in the two soil vapor samples collected during this assessment (i.e. “non-detect”).
Given there were no detections of VOCs above their corresponding laboratory reporting limits, the off-site west-adjoining fuel station does not present a VEC to the Subject Property. No further assessment appears to be warranted.

1 Introduction
Stantec Consulting Services, Inc. (Stantec) has performed a Phase II Environmental Site Assessment (ESA) of the property located at 35 15 Argonaut, Aliso Viejo, Orange County, California (the “Subject Property” Figure 1), on behalf of Brandywine Homes (the “Client”). The work was performed according to the requirements of the Master Services Agreement between Brandywine Homes and Stantec (the “MSA").
1.1 Property Description and Operations
The Subject Property consists of approximately 4.35 acres of land associated with Assessor’s Parcel Numbers (APNs) 623-093-10 and 623-093-11, and the address of 15 Argonaut, Aliso Viejo, Orange County, California. According to records obtained through Environmental Data Resources (EDR), the Subject Property appears to have been vacant from at least the 1930s to 1980s and was commercially developed with one structure and asphalt parking lot by 1989 in its present-day configuration. The Subject Property building is currently vacant. The adjoining properties and vicinity are developed with commercial/light industrial businesses and residential properties. A Subject Property Location Map is provided as Figure 1. A Subject Property Vicinity Map illustrating the main features of the Subject Property and vicinity is provided as Figure 2.
1.1.1 Site Geology and Hydrogeology
According to a previous environmental site assessment for the Subject Property by EMG in 2016, the general geology of the Subject Property and vicinity is comprised of sandstone, mudstone, siltstone, evaporite and conglomerate, dating from the Oligocene to the Pliocene epochs (EMG, 2016).
According to California DOC Earthquake Zone Map (Department of Conservation Map Server (ca.gov)), the Subject Property is not located within an Alquist-Priolo (AP) Earthquake Fault Zone boundary. The closest fault zone is located approximately 20 miles to the northwest of the Subject Property. The Subject Property lies within a Landslide Zone.
The Subject Property lies within the Aliso Creek Watershed located in southern Orange County. The Watershed is part of the Laguna subunit of the San Juan Hydrologic Basin. The Basin is comprised of coastal watersheds which drain to the Pacific Ocean. The Aliso Creek Watershed drains approximately 30 square miles and has limited water-bearing formations, which include two alluvial aquifers and one deeper aquifer. The alluvial aquifers are separated by a shale formation. Groundwater extraction is limited within this area due to saltwater intrusion (Orange County, 2018).
Site specific groundwater investigations were not conducted during this ESA; however, according to a 2022 Second Half Groundwater Monitoring Report for a release site located approximately one mile to the north, groundwater in the vicinity is estimated to be approximately 7.19-15.64 feet below top of well casing (btoc) with a flow direction generally to the east. 1770

1.2 Background
The following potential vapor encroachment condition (pVEC) and recognized environmental condition (REC) were identified during the Phase I ESA completed for Subject Property dated July 14, 2025:
• A west-adjoining fuel station located at 23022 Aliso Creek Road is listed as a gasoline service station since 1996 that reportedly houses three active underground storage tanks (USTs) installed between 2004 and 2016. The USTs range from 10,000 to 20,000 gallons in size and contain diesel, regular and premium unleaded fuel. A minor spill of two gallons of fuel was reported in 2018 due to a vehicle overfill onto concrete. The spill was cleaned by onsite personnel. The site received permit-related violations between 2014 and 2016 which were returned to compliance. No releases are reported at the site. Given the proximity of the fuel station to the Subject Property, and no documented assessment of soil, soil vapor, or groundwater at the site, as well as inferred groundwater flow to the east, this site represents a potential VEC and is considered a REC for the Subject Property. 1771

2 Field Investigation
All work was conducted under the direct supervision of a State of California professional geologist.
Stantec provided the services of a field geologist to supervise and direct all on-site activities performed during this investigation, which included the following:
• Stantec obtained an Underground Service Alert (USA) ticket number prior to commencement of drilling activities. Additionally, Stantec subcontracted a private utility locator to clear all proposed boring locations.
• On August 26, 2025, Stantec personnel oversaw the advancement of three (3) soil vapor borings (SV-1 through SV-3) to 5-feet below ground surface (bgs) on the Subject Property. • On August 28, 2025, Stantec personnel oversaw soil vapor sampling of the newly-installed soil vapor probes at the Site. Soil vapor sampling was performed by A&R Laboratories (ARL), and analyzed on-site in a mobile laboratory. Soil boring SV-2 was submerged in water due to irrigation and no sample could be collected.
All boring locations advanced during this investigation are depicted on Figure 2.
2.1 Pre-Field Activities
In accordance with federal Occupational Safety and Health Administration (OSHA) regulations (29 CFR, Section 1910.120), Stantec developed a site-specific Health and Safety Plan (HASP) for the Property. All Stantec personnel and subcontractors associated with the project were required to be familiar with and comply with all provisions of the HASP.
Stantec visited the Property to mark the proposed boring locations. Subsequent to the marking, underground service alert (USA) was notified at least 72-hours prior to the commencement of drilling activities.
2.2 Investigation
All soil and soil vapor borings were advanced using a hand auger to a maximum explored depth of 5.5 feet below ground surface (bgs). Soil vapor samples were collected to assess for the presence of VOCs.
Boring locations are depicted on Figure 2.
2.2.1 Soil Boring and Sampling Protocols
All locations were cleared of belowground utilities by clearing the top 5.5 feet of soil using a hand auger.
The soils from each of the direct push borings were visually examined by Stantec field personnel who classified the soils in accordance with the Unified Soil Classification System (USCS). A photo-ionization detector (PID) was used to monitor/field screen the soils collected. Field screening for VOCs was 1772

Project: 185806577 2
achieved by removing the soil from the uppermost sample sleeve and placing it in a zip-lock type baggie.
A PID probe was inserted into the baggie to monitor the headspace for VOC vapors.
Following classification and VOC vapor evaluation, the soil samples were carefully packaged for chemical analysis by sealing the ends of the acetate liner with Teflon ® sheeting, covering with plastic end caps, and sealing with non-VOC containing tape. The sample containers were labeled with the appropriate identification information (boring number, sample depth, sample collection date, and sample collection time). The samples were logged on a chain-of-custody form and delivered to a state certified laboratory for analysis. Laboratory analysis is discussed in Section 3.0.
2.2.2 Soil Vapor Probe Installation
At the completion of drilling to the target depths, select soil borings were converted to soil vapor monitoring points at the five-foot depth interval. Subsurface soil vapor probe installation was performed in accordance with the July 2015 DTSC “Advisory - Active Soil Gas Investigations” (DTSC Advisory).
Each sample probe was constructed with a 1-inch-long Airstone sampling screen set at the prescribed sampling intervals. Each of the sampling screens was constructed with a permeable Airstone vapor tip connected to ¼-inch outer diameter Nylaflow tubing that was lowered to the bottom of the borehole and backfilled with filter sand, until approximately 12-inches of filter pack was placed. A transition seal consisting of approximately 12-inches of dry bentonite was then placed above the filter pack, followed by an annular seal consisting of hydrated bentonite until the next sampling interval was reached. The sequence was then repeated to install the second monitoring point, and/ or completely backfill the borehole.
At the surface, the exposed nylon tubing was capped with tight fitting plastic endcaps and labeled to indicate sampling depth. After installation of the soil vapor sample probes, subsurface conditions were allowed to equilibrate a minimum of 48-hours prior to leak testing and sample collection on August 28, 2025.
2.2.3 Soil Vapor Sampling
Soil vapor samples were collected on August 28, 2025, in accordance with the methods and procedures outlined by the DTSC Advisory, a minimum of 48-hours after installation, in order to allow for equilibration.
Prior to sampling, a shut-in test was conducted on the sampling train to ensure all connections and fittings were airtight. The shut-in test was performed on the sampling train by applying a vacuum of 100 inches of water to the sampling train and monitoring magnehelic gauges for a pressure drop for one minute. If loss of vacuum was observed, the fittings were adjusted as needed until no vacuum loss was observed during subsequent shut-in tests.
After the sampling equipment passed the shut-in test, the probes were purged using an air pump outfitted with a low-flow module to remove internal air from the sample train (calculated from the internal volume of the tubing and probe tip); the void space of the sand pack around the probe tip; and the void space of the dry bentonite (in the annular space). Three internal volumes were purged from each sampling location at a rate less than 200 milliliters per minute (ml/min).
1773

Project: 185806577 3
Immediately following purging the internal volumes, the soil vapor samples were collected by the soil vapor sampling technician into pre-cleaned glass syringes at a rate of 200 ml/min. A tracer compound of was placed above the surface seal and along the sampling train to evaluate the integrity of the seal. No tracer compounds were detected in the soil vapor samples collected during this investigation. The soil vapor samples were transported to the on-site mobile laboratory and analyzed within 30 minutes of sample collection.
2.2.4 Field Equipment Cleaning Procedures
To maintain quality control during drilling operations, all drill rods and reusable soil sampling equipment was decontaminated using a triple bucket rinse. Prior to drilling at a given location or sampling interval, all equipment coming in direct contact with soil samples was scrubbed with an Alconox scrub solution followed by a clean tap water rinse and then a final distilled water rinse. The disposable acetate soil sample liners were used for one sampling interval and then discarded. 1774

3 Laboratory Testing Program
Soil vapor samples collected during this investigation were delivered under COC to the on-site mobile laboratory operated by A&R Laboratories (ARL), based in Ontario, California. All soil vapor samples were analyzed for VOCs USEPA test method 8260 by the on-site mobile laboratory.
ARL are certified to perform hazardous waste testing by the California State Water Resources Control Board Environmental Laboratory Accreditation Program (ELAP).
Complete laboratory analytical results are presented on the laboratory data sheets attached as Appendix A.

4 Investigation Results
4.1 Field Observations
Stantec personnel oversaw a geophysical subsurface survey to clear all locations before ground disturbance. No utility conflicts were identified at proposed boring locations.
Soils encountered during this investigation consisted of sand with silt and clay with sand to the maximum explored depth of 5.5 feet bgs. PID readings were measured at 0.0 parts per million by volume (ppmV) at all locations. No olfactory response, staining, or odors were observed in any borings advanced during this investigation. All borings locations are shown on Figure 2.
4.2 Analytical Results
The laboratory test results from this investigation are discussed below and were compared to the DTSC Human and Ecologic Risk Office (HERO), Note Number 3, Modified Indoor Air Screening Level (MIASL) using an attenuation factor (AF) of 0.03. Given the Subject Property is contemplated as a future residential community, residential-use screening criteria were used for evaluation of the analytical data collected during this investigation.
Laboratory analytical test results from this assessment are attached as Appendix A.
4.2.1 Soil Vapor Results
Soil boring SV-2 was submerged in water due to irrigation and no sample could be collected. There were no detections of any VOCs above their respective laboratory reporting limits in the two soil vapor samples collected during this assessment (i.e. “non-detect”).

5 Discussion and Recommendations
Stantec has completed an evaluation of subsurface conditions on the Subject Property.
Given there were no detections of VOCs above their corresponding laboratory reporting limits, the off-site west-adjoining fuel station does not present a VEC to the Subject Property. No further assessment appears to be warranted.

Description:
The project site is located at 15 Argonaut, Aliso Viejo, CA 92656.
The project consists of 58 townhomes with associated drive aisles, sidewalks, parking, and landscaping. The north and west boundaries feature a 2:1 slope where v-ditches intercept undeveloped run-on and divert it through the site for untreated discharge into Argonaut. Because the development creates 48,700 square feet of impervious surface— exceeding the 10,000-square-foot threshold—it is classified as a Priority Project, requiring permanent Best Management Practices (BMPs) and water quality treatment for all onsite runoff.

2.2 Post Development Drainage Characteristics
The proposed redevelopment replaces an existing commercial property that slopes from northwest to southeast. The northern and western boundaries feature a 2:1 hillside slope with v-ditches that intercept runoff; under the new design, this drainage will be conveyed through underground pipes to the front of the property, maintaining existing hydraulic patterns. Onsite stormwater will be collected via area drains and directed to a biofiltration system for treatment before being pumped for final discharge into Argonaut.
2.3 Property Ownership/Management
The property is owned by Brandywine Homes.

3.1.2 Infiltration-Related Characteristics
3.1.2.1 Hydrogeologic Conditions
Regionally, the subject site is located in the Peninsular Ranges geomorphic province, which characterizes the southwest portion of southern California where right-lateral major active fault zones predominately trend northwest-southeast. The Peninsular Ranges province is composed of plutonic and metamorphic rock, with lesser amounts of Tertiary volcanic and sedimentary rock, Quaternary drainage in-fills and sedimentary veneers.
3.1.2.2 Soil and Geologic Infiltration Characteristics
Monterey Formation: The Miocene-age Monterey Formation observed onsite primarily consists of silty sandstone, clayey sandstone, sandy claystone, sandstone, and claystone. The fine grained silty sandstone onsite is pale brown, white, dark yellowish brown, and brown in a slightly moist to moist and medium dense to very dense condition. The fine grained clayey sandstone onsite is pale brown, white, dark brown, brown, gray, light gray, dark grayish brown, and bluish gray in a slightly moist to moist and medium dense to dense condition. The sandy claystone onsite is dark 1810

brown, brown, and gray in a moist and stiff to very stiff condition. The very fine to fine grained sandstone onsite is pale brown, yellowish brown, grayish pale brow, and orange in a slightly moist and medium dense to very dense condition. The claystone onsite is dark brown to brown in a moist and very stiff condition. This unit was logged to a depth of 51.5 feet below the ground surface and is overlain by a thin layer of asphalt.
3.1.2.3 Geotechnical Conditions
Groundwater was not encountered during our subsurface investigation. Based on state-provided information, the historic-high groundwater is greater than 20.0 feet below the ground surface (CGS, 2001). The most recent groundwater data retrieved from the nearest groundwater monitoring site, site ID 336555N1176965W001, was recorded in 2024 and indicates groundwater was approximately greater than 60.0-feet at that time (CDWR, 2025).
3.1.2.4 Summary of Infiltration Opportunities and Constraints of Existing Site Infiltration will not suffice, due to the existing constraints with the existing soil conditions.
Therefore, the project will require biofiltration.
3.2 Proposed Site Development Activities
3.2.1 Overview of Site Development Activities
The proposed site development consist of 58 townhomes, drive aisles, sidewalks, and landscape amenities.
3.2.2 Project Attributes Influencing Stormwater Management Potential pollutant-generating activities include:
• Automobile repair and maintenance
• Automobile washing/ parking
• Home and garden care activities
• Pet Waste
• Green waste
• Irrigation
Plants known to have excessive root systems should also be avoided near structural improvements as they can cause heave conditions. Drought-resistant and maintenance-free plant species are recommended.

3.2.3 Effects on Infiltration and Harvest and Use Feasibility The existing soil type does not allow for adequate infiltration; however the site has been designed to try to drain hardscape areas into pervious areas to help increase the amount of natural infiltration. Harvest and use feasibility was also considered. A comparison of the Design Capture Volume (DCV) in gallons was compared to an estimated net wet season total water use (ETWU) in gallons. The results show that the DCV is greater than the ETWU, which makes harvest and use infeasible. Please see calculations in the Attachments. The proposed biofiltration system is required to treat the majority of the low flow runoff, due to the inability of adequate infiltration of the site with the existing soil type.
3.3 Receiving Waterbodies
Stormwater runoff from the project site discharges onto Argonaut, where it is conveyed via curb and gutter eastward to a catch basin. From there, flows are directed into Aliso Creek, eventually discharging into the Pacific Ocean.

3.4 Stormwater Pollutants or Conditions of Concern
Residential water quality issues and related potential pollutants include the landscape planning and site design of the project. These proposed swales can trap pollutants such as suspended solids, oil and grease, as well as trace metals and it will reduce the flow velocity of storm water runoff. 1812

The proposed project condition does not result in an increase in runoff, as demonstrated in the Drainage Report. The existing condition generates a higher runoff due to its commercial land use classification. Therefore, hydromodification requirements are satisfied, as the project does not increase runoff from existing to proposed conditions. See supporting calculations in the attachments.

Section 4 Site Plan and Drainage Plan
4.1 Drainage Management Area Delineation
The Project will be characterized with four drainage management areas, however only one area (DMA 1) will be required to treat runoff. The other three areas are from hillside runoff which will be routed through the site via underground storm drain pipes and will be discharged to Argonaut.
DMA 1 consists of all proposed impervious areas and landscaped/pervious areas (see WQMP Site Plan). More specifically, DMA 1 will include flows originating from the buildings, drive aisles, hardscape, and landscape areas. Runoff from DMA 1 will be treated by a biofilter and then pumped to Argonaut.
4.2 Overall Site Design BMPs
Minimize Impervious Area - This Project was designed as a single-family residence with appropriate hardscape areas and drive.
Preserve Existing Drainage Patterns and Time of Concentration - Existing drainage patterns were preserved by limiting the grading area and preserving slope directions.
Disconnect Impervious Areas – Disconnect impervious areas through the use of landscape planters.
Protect Existing Vegetation and Sensitive Areas - Existing vegetation will be supplemented and/or replaced with additional vegetation.
Revegetate Disturbed Areas - The portion of the disturbed area that is pervious will be revegetated or overlain with synthetic grass.
Soil Stockpiling and Site Generated Organics - There will be no soil stockpiling or site generated organics as landscaping will be maintained by the owner on a regular basis.
Water Efficient Landscaping - Water efficient landscaping will be implemented.
Slopes and Channel Buffers - Slopes will be either undisturbed or vegetated.

Section 5 Low Impact Development BMPs
5.1 LID BMPs
The project proposes to use a proprietary biotreatment system to treat stormwater runoff. A conventional biotreatment system was evaluated and sized (see the attached calculations); however, the proposed site development does not provide sufficient space to accommodate a conventional biotreatment facility. Although a proprietary biotreatment system is not the preferred option in the BMP selection process, it has been determined to be the only feasible treatment alternative for this site while meeting the project constraints.
The proposed project consists of a townhome development that has been designed to provide the minimum number of dwelling units necessary to maintain project feasibility while satisfying applicable fire access, grading, and life safety requirements. Any reduction in the proposed unit yield would result in an economically infeasible project due to fixed development costs and required infrastructure improvements.
Infiltration-based and volume retention BMPs were evaluated; however, these approaches are not feasible for the site. As documented in the project geotechnical/soils report, onsite soils are not suitable for infiltration; therefore, infiltration-based compliance is not viable.
The site is also constrained by the required infrastructure improvements necessary to support the development, including domestic water service (serving residential units and fire protection hydrants), sanitary sewer facilities, storm drain improvements for both hillside and developed area drainage, and electrical utilities. These improvements, in combination with grading constraints and fire access requirements, do not allow sufficient area for implementation of a conventional flowthrough or storage-based treatment control system.
Based on the above constraints, the project qualifies as a space-limited project under Section 4.2.4.1, Option 2 (Project-Specific Space Allocation) of the WQMP requirements. A proprietary biotreatment system is therefore proposed as the most feasible treatment control BMP due to its compact footprint and ability to provide the required water quality treatment within the constrained development envelope without modification to the approved site layout or reduction in unit count.
5.1.1 Hydrologic Source Controls
No HSC’s are applicable:
HSC-1: Not applicable due to the lack of infiltration potential at the site.
HSC-2: Not applicable due to the lack of infiltration potential at the site.
HSC-3: Not feasible because the required 20- to 30-foot tree canopy diameter cannot be achieved within the site constraints.
1820
Water Quality Management Plan (WQMP)
Presidio Section 5
HSC-4: Not feasible because overflow dispersion requires a minimum 8-foot separation from buildings, which cannot be accommodated by the proposed site layout.
HSC-5: Not feasible due to the significant cost impacts to the project.
HSC-6: Not applicable due to the lack of infiltration potential at the site.
5.1.2 Structural LID BMP for DMA 1
Proprietary biotreatment (BIO-7) BMP’s will be used to treat the stormwater runoff for DMA 1.
This BMP satisfy the LID performance standard using the Flow-Based Compact Biofiltration Sizing Method. The required design flow rate for the BIO-7 BMP was calculate as follows:
Time of concentration (Tc) = 10 minutes
The time of concentration was calculated using the Orange County Hydrology Manual (OCHM) time of concentration nomograph (see time of concentration nomograph in Attachments). The time of concentration found by using the OCHM nomograph is 10 minutes. = ×

6.1 Points of Compliance
Point of Compliance is considered to be the manhole where all storm runoff is captured and flows to a single point. The Point of Compliance was selected since runoff flows to this location.
6.2 Pre-Development (Natural) Conditions
The pre-developed site is assumed to be a straight grade from the top of the slope on the west side to the existing street on the east side with a slope of greater than 15%.
6.3 Post-Development Conditions and Hydromodification BMPs The post development site will consist of 58 townhomes, drive aisles, walkways, and landscape amenities. The project will not discharge more runoff than allowed by hydromodification requirements.
6.4 Measures for Avoidance of Critical Coarse Sediment Yield Areas
There are no potential critical coarse sediment yield areas on the site per the potential coarse sediment map in Appendix N of the technical guidance document (see the Appendix – Potential Course Sediment Areas Map).
6.5 Hydrologic Modeling and Hydromodification Compliance The project site is located within a Hydromodification control zone and is required to mitigate any increase in runoff peak flow rates between existing and proposed conditions. As documented in the attached South Orange County Hydrology Manual, storm drain chamber were sized to mitigate runoff per hydromodification requirements. Therefore, the project meets and exceeds the minimum Hydromodification requirements.

Unlike water in sanitary sewers (from sinks and
toilets), water in storm drains is not treated or
cleaned before entering our waterways and
should never contain any pollutants. Many
pools and spas are plumbed to drain directly to
the sanitary sewer. If yours is not, you must take
necessary steps before draining to landscaped
areas or into the storm drain.
While the focus of this brochure is pools and
spas, these requirements also apply to water

pH is between 6.5 and 8.5.
Residual chlorine does not exceed 0.1 mg/L
(parts per million).
Water is clean and clear, free of any unusual
coloration, dirt, or algae.
There is no discharge of fi lter media or acid
cleaning wastes.
Saltwater pools must be discharged to the sanitary
sewer, landscaped areas, or other pervious
surfaces that can accommodate the volume of
water. Alternatively, they can be discharged
directly to a naturally saline body of water.
You can fi nd out how much chlorine is in
your water by using a pool testing kit. Before
discharging, reduce chlorine to 0.1 mg/L by
discontinuing its use for a few days, or by using
dechlorinating chemicals purchased from a
local pool supply company. Always follow the
instructions that come with any products you use.
By following these requirements, you will make
a signifi cant contribution towards keeping
pollutants out of Orange County’s waterways.
You can help protect organisms that are
sensitive to pool chemicals and maintain the
health of our environment.
• When possible, discharge all water to the
sanitary sewer.
• Monitor the drain hose to prevent leakage.
• Remove trash and debris in the fl ow path
between the pool or spa and storm drain.
• Monitor the rate of fl ow to ensure that draining
the pool or spa does not cause erosion or fl ooding.
• To prevent vectors and algae do not allow
dechlorinated water to stand for more than
72 hours.
• Clean your pool regularly, maintain consistent
and adequate chlorine or sodium bromide
levels, monitor pH levels, and maintain your
fi ltration and circulation system.
• Rinse pool fi lters and diatomaceous earth fi lters
in landscaped areas where water and debris can
readily soak into the soil.
• When draining pools or rinsing fi lters to a
landscaped area, cover any landscape drains to
prevent water from reaching the storm
drain system.
• Used diatomaceous earth should be tossed
in with solid garbage. It should never be
discharged into storm drains or any place where
it may wash into streams, rivers, or the ocean.
• Store chemicals indoors.

Every property with sewer service owns
a private sewer line, also known as a
“private lateral.” The private lateral carries
wastewater from indoor plumbing fi xtures,
like toilets‚ sinks‚ and dishwashers, to the
public sewer line under the street. The sewer
system transports wastewater to treatment
plants before being released. It is important
to maintain your private laterals to prevent
sewage spills that can reach our storm drains.
Unlike water in sanitary sewers, water that
fl ows into storm drains is not treated before
entering our waterways and should never
contain sewage.
Property owners are responsible for
maintaining their private laterals from the
connection at the home or business to the
connection with the public sewer; this can
include areas under the sidewalk and the
street. Inadequate maintenance of laterals
can result in sewer backups and spills.
Operation and maintenance of the local,
public, and regional sewer lines, on the other
hand, are the responsibility of the sewer
agency.* Visit the link inside for agency

Sewage spills and backups occur when the
wastewater being transported is blocked and
overfl ows or leaks out of broken pipes inside or
outside of your building. Once out of the pipe,
the sewage can discharge to the curb, gutter,
and storm drain system, which fl ows to local
waterways. Sewage spills can cause health
hazards, beach closures, damage to homes and
businesses, and threaten the quality of our local
waterways. As a property owner, if sewage from
your property discharges to a gutter or storm
drain, you may be subject to fi nes, penalties, or
increased rates.
Common Causes
BLOCKAGES
Common causes of blockages include
• Flushing anything other than toilet paper,
including: wipes (even those advertised as
“fl ushable”), feminine products, rags, and
other items.
• Fats, oils, and grease (FOG) can get into the
private lateral from household drains, as
well as from poorly maintained commercial
grease traps and interceptors.
• Tree roots can fi nd their way into cracked
or broken sewer laterals and
cause blockages.
STRUCTURAL PROBLEMS
Common structural problems include
• Broken/cracked pipes.
• Deteriorated, missing, or broken cleanout caps.
• Aging or undersized sewers.
Keep Your Private Laterals
Functioning Properly
Prevent Blockages
Remember, the drain is not a dump!
• Only fl ush toilet paper down the toilet.
• Use a mesh sink strainer to catch food scraps
before they go down the drain.
• Scrape food scraps into a designated food
waste/organics receptacle before rinsing dishes
and utensils in the sink.
• After cooking at home, let grease cool then
pour or scrape it into a metal can. When the
can is full, dispose of grease properly.
• For businesses, grease traps or interceptors
must be serviced regularly. Have spill kits
readily available for cleaning up spills.
• Do not plant trees or large shrubs above or
within several feet of your sewer laterals.
Structural Maintenance
• Contact a licensed plumber to determine the
optimal maintenance schedule.
• Perform periodic cleaning to eliminate grease,
debris, and roots from private laterals.
• Repair or replace deteriorated or damaged
private laterals as soon as possible.
• Install a backfl ow device to prevent sewage
from ending up in your home or business.
Identify & Report Sewage
Spills or Backups
Know the Signs
Sewage spills can cause damage to your property,
the environment, and our local waterways. Look
for potential signs of a spill, which may include:
• Drains are operating slower than normal and
continuing to slow over time.
• Drains backup inside of buildings.
• Unusually wet or soggy ground in your yard
that may be accompanied by odors.
• Leakage from sewer cleanouts, outside
drains, or manhole lids.
Report Sewage Spills
Immediately
• If you suspect a sewer backup or leak, contact a
licensed plumber.
• If you observe a sewer spill from a cleanout or
manhole, contact your sewer agency.*
• Plumbers should contact the sewer agency prior
to pushing roots from private sewer laterals to
the sewer main.
Alternatively, you can contact the 24-Hour
Pollution Reporting Hotline by calling
1-877-89-SPILL (1-877-897-7455) or visiting
myOCeServices.ocgov.com.
Spill Control & Containment
• Turn off main water supply or stop all water use.
• Have a plumbing professional clear the
blockage and make necessary repairs.
• Keep people and pets away from the
affected area.
• When safe, place sandbags or other material
in the fl ow path of the spill to control, contain,
and prevent sewage from entering the storm
drain system.

Landscape
& Sustainable
Water Use Guide
Making Your
Landscape
Stormwater-Safe
Runoff is the flow of water from your property that
doesn’t get absorbed into the ground. When harmful
substances like pesticides, fertilizer, and dirt are
handled improperly, this water can pick them up
on its way to the storm drain system where it flows
untreated to our creeks, rivers, and ocean. There are
simple actions you can take to collect runoff and use
it on site to maintain your landscape and protect our
water resources.
This guide will help you use rainwater as a resource
to waste less water and keep your landscape
stormwater-safe. Planting OC Garden Friendly
plants, proper watering practices, and harvesting
and using rainwater are terrific ways to beautify your
landscape while protecting our water resources.

Watering
Proper irrigation practices are critical to protect Orange County’s water bodies.
• Utilize smart irrigation controllers and, and/or soil moisture sensors. These can help manage your garden’s
water needs to waste less water.
• Take advantage of a drip irrigation system to directly water plant roots. This reduces water loss and runoff.
• Install rotating sprinkler nozzles to spread water
more uniformly across your landscape.
Rainwater Collection and Use
In Orange County, 60%-70% of water is used for irrigation and other outdoor uses. Collecting and using rainwater are great ways to decrease water usage.
• Direct downspouts to flow towards vegetated areas to
reduce runoff and use a splash block to prevent erosion. • Install a rain barrel to collect rainwater from roofs and use for landscape irrigation. Make sure it has a screen, spigot to siphon water for use and an overflow tube.
• Build a rain garden using OC Garden Friendly plants and other landscape materials.
Rebates
Beautify your landscape in stormwater-safe ways by
utilizing rebates from your local water district or the Municipal Water District of Orange County (MWDOC).
Save money on water-efficient devices like smart irrigation controllers, high-efficiency nozzles, soil moisture sensors, and drip irrigation systems. Also, upgrade your landscape with their conversion rebates to replace turf with OC
Garden Friendly plants. These rebates can change
frequently, so check with your local water agency and
MWDOC (mwdoc.com/rebates) regularly.

Did you know that just
one quart of oil can pollute 250,000
gallons of water?
A clean ocean and healthy creeks, rivers,
bays and beaches are important to Orange
County. However, not properly disposing of
used oil can lead to water pollution. If you
pour or drain oil onto driveways, sidewalks
or streets, it can be washed into the storm
drain. Unlike water in sanitary sewers (from
sinks and toilets), water in storm drains is
not treated before entering the ocean. Help
prevent water pollution by taking your used
oil to a used oil collection center.
Included in this brochure is a list of
locations that will accept up to five gallons
of used motor oil at no cost. Many also
accept used oil filters. Please contact the
facility before delivering your used oil. This
listing of companies is for your reference
and does not constitute a recommendation
or endorsement of the company.
Please note that used oil filters may not be
disposed of with regular household trash.
They must be taken to a household
hazardous waste collection or recycling
center in Anaheim, Huntington Beach,
Irvine or San Juan Capistrano. For

REQUIREMENTS
TO PREVENT
POLLUTION WHEN
COMPLETING
HOME
IMPROVEMENT
PROJECTS
Home improvement activities such as
remodeling, stucco repair, painting,
landscape improvements, and power
washing can generate pollution that can
harm Orange County’s waterways. These
pollutants can include paint, debris,
chemicals, and more. If not properly
managed, these pollutants can flow into
Orange County’s rivers, creeks, channels,
and ocean through our storm drain
system. Unlike water in sanitary sewers
(from sinks and toilets), water that flows
into storm drains is not treated before
entering our waterways and must never
contain pollutants generated by home
improvement projects.
POLLUTION
PREVENTION
No matter how large or small your
home improvement project is, pollution
prevention must always be part of
the process. Use the required best
management practices (BMPs) listed here
to protect our waterways as you make your
improvements. Whether you do-it-yourself
or hire a contractor, you are responsible for
preventing pollution.

Update Your Irrigation
System and Landscape
Switch to Rotating Sprinkler Nozzles: Consider
replacing your sprinkler heads with rotating sprinkler
nozzles. Rotating nozzles water more uniformly and
efficiently, significantly reducing your outdoor water
use. Check with your local water agency for available
rebates on rotating nozzles, irrigation controllers,
and other water efficient devices.
Get Smart: Consider using smart irrigation controllers.
Smart irrigation controllers have internal clocks as
well as sensors that will turn off the sprinklers
in response to environmental changes. If it is raining, too windy, or too cold, the smart irrigation controller will automatically shut off the sprinklers.
Drip don’t Douse: Drip irrigation systems prevent
runoff from carrying pollutants into the storm drain
by watering only the targeted plants using low
volumes of water.
Reduce the Need: Replace water “thirsty” plants
and grass types with water efficient natives or OC
Garden Friendly plants to save water and reduce
the need for pesticides and fertilizer. Please see
the California Friendly® Landscape Maintenance
Guide produced by the Metropolitan Water District
of Southern California** and associated Southern
California Water Agencies for more information.
Group Plants: When adding to or redesigning
your landscaping, plants that require similar
watering needs can be planted together. Grouping
plants with similar watering needs helps prevent
unnecessary watering.

3 STORMWATER PROGRAM 1839
What is Irrigation Runoff
and How Does it Lead to
Pollution?
Irrigation runoff is water flowing off landscaped
areas, which can carry pollutants to our storm
drains and waterways. It is usually the result
of landscape overwatering, and mismanaged
irrigation systems. Runoff can carry pesticides,
fertilizers, pet waste, and other pollutants into
our storm drains, which flow untreated to the
ocean. Explore the tips below to find out how to
prevent irrigation runoff.
Broken or leaky
sprinklers can waste
thousands of gallons
of water per month
and significantly
increase the amount
of runoff from your
yard. Repairing
sprinklers can
prevent runoff
from entering our
waterways and save
you money.
FIX LEAKS
Adjust the direction
of your sprinkler
heads so water
does not spray
on sidewalks,
driveways or roads.
By simply adjusting
the direction of your
sprinklers, you can
save water, prevent
irrigation runoff,
and keep your
landscape healthy.
PROPER AIM
Watering early in the morning before sunrise
will reduce water loss due to evaporation. Wind
also tends to die down in the early morning, so
the water will irrigate the lawn as intended.
WATER AT SUNRISE
Use an irrigation
timer to minimize
runoff and
maximize water
absorption. Water
districts often
provide irrigation
schedules to
determine the
best water scheme
for your yard.
Contact your
water provider for
a weekly irrigation
schedule.
SET A TIMER
RUN YOUR
SYSTEM
Run and observe
your irrigation
system through
its entire cycle
seasonally
(twice a year) to
look for leaks,
misaligned
sprinkler heads,
and areas of
ponding and/or
runoff.
Garden hoses with
automatic shutoff
nozzles can use less
water than sprinkler
irrigation systems.
Hand watering also
ensures only those
areas that need water
get it and prevents
irrigation runoff. An
easy alternative
to sprinklers, hand
watering can help keep
our waterways clean!
HAND WATER
PLANTS
Prevent fertilizers
and pesticides
from entering
our waterways by
not watering your
lawn 48 hours after
application and
stopping application

Know Your Irrigation
System and Landscape:
Different types of grass and plants have differing
water needs. This also changes throughout the
year, with cooler months typically requiring less
water than warmer months. Ask your landscape
maintenance provider or contact the University
of California Cooperative Extension Master
Gardeners* for questions regarding landscape
watering needs.
WATER BY PLANT TYPE AND SEASON
Adjusting your watering schedule when it rains
prevents unnecessary watering that can lead
to runoff. Keep an eye on the weather forecast
and skip your normal watering schedule
before, during, and after a rain to help keep our
waterways clean and your landscaping looking
its best.
RAIN SKIP
Running multiple, shorter cycles with an hour
break in between allows the water to infiltrate
into the ground so it does not run off.
CYCLE AND SOAK
LEAST TOXIC FIRST
Limit pesticide use by using nonchemical
methods, integrated pest management, or leasttoxic pesticides whenever possible. Contact the University of California Cooperative Extension
Master Gardeners* for alternative suggestions
and related guidance.

To Protect our waterways
Who is H2OC?
H2OC is YOU! H2OC is also a
cooperative stormwater program
which includes all 34 cities in Orange
County, the County of Orange,
and Orange County Flood Control
District (OCFCD). Clean and healthy
beaches, creeks, rivers, bays,
wetlands, and ocean are important
to Orange County. H2OC provides
resources to residents and businesses
to encourage personal action and
prevent polluted runoff from entering
our waterways.
Join Us
Contact
Visit h2oc.org to learn more about runoff,
water pollution, and how you can be the
solution to runoff pollution and protect our
water resources.
24-hour Pollution Reporting Hotline:

For emergencies, dial 911
Unlike water in sanitary sewers (from sinks
and toilets), water in storm drains is not
treated or cleaned before entering our
waterways and should never contain any
pollutants. Landscaping and gardening can
generate a variety of waste products which
can become pollutants like dirt, fertilizers,
pesticides, green waste (grass clippings,
prunings, branches), and other harmful
substances. If not properly managed, these
pollutants can be transported to Orange
County’s creeks, rivers, and ocean through our
storm drain system.

BEST MANAGEMENT
PRACTICES
THANK YOU FOR PROTECTING OUR
WATERWAYS FROM RUNOFF POLLUTION.
Landscaping
• Regularly inspect your sprinkler system for
runoff and leaks and fix immediately. Check
backup battery and adjust system regularly.
• Use smart irrigation controllers, drip irrigation,
soaker hoses, high-efficiency sprinkler nozzles,
or micro spray systems. Check with your local
water agency or the Municipal Water District
of Orange County (MWDOC) for currently
available rebates.*
• Hand water your landscape to
reduce overwatering.
• Cover bare soil with groundcover or mulch to
prevent erosion and reduce runoff.
• Check the weather forecast and refrain from
watering or using chemicals like fertilizers
and pesticides 48 hours before or after rain
is predicted.
• Sweep hardscapes and rinse patio furniture on
permeable surfaces to prevent runoff.
Gardening
• Use integrated pest management (IPM) to
target specific pests in problem areas instead
of widespread chemical use.
Runoff of anything other than clean rainwater is
prohibited from entering the storm drain system.
Here’s what you can do while maintaining your yard
and garden to protect our creeks, rivers, and ocean.
For more on waterway-safe landscaping and gardening, please visit https://h2oc.org/resources/pollution-prevention-for-residents/lawn-and-garden-care/ or scan the QR code. • If pesticides or herbicides are necessary, follow
the manufacturer’s instructions on the label.
• Plant OC Garden Friendly plants to reduce
the amount of water, fertilizers, and
pesticides needed.
Containment
• Protect stockpiles and materials from wind and
rain by storing them under tarps or secured
plastic sheeting.
• Bulk deliveries of landscape materials such
as mulch and soil, should be delivered to
driveways and covered with a tarp.
• Store chemicals indoors or in a dry and
covered area.
Proper Disposal
• Sweep up solid waste spills immediately. If the
spill is liquid, apply an absorbent material then
sweep it and dispose of it properly.
• Take unwanted pesticides, fertilizers, and
herbicides to a Household Hazardous Waste
Collection Center.**
• Dispose of green waste by composting it or
placing in your organics waste bin.

Maintenance Procedures
Screening Device

The Isolator® Row Plus
Introduction
An important component of any Stormwater Pollution Prevention Plan is inspection and maintenance. The StormTech Isolator Row Plus is a technique to inexpensively enhance Total Suspended Solids (TSS), Total Phosphorus (TP), Total Petroluem Hydrocarbons (TPH) and Total Nitrogen (TN) removal with easy access for inspection and maintenance.
The Isolator Row Plus
The Isolator Row Plus is a row of StormTech chambers, either SC-160, SC310, DC-780, SC-800, MC-3500, MC-4500 or MC-7200 models, are lined with filter fabric and connected to a closely located manhole for easy access.
The fabric lined chambers provide for sediment settling and filtration as stormwater rises in the Isolator Row Plus and passes through the filter fabric. The open bottom chambers allow stormwater to flow vertically out of the chambers. Sediments are captured in the Isolator Row Plus protecting the adjacent stone and chambers storage areas from sediment accumulation.
ADS Isolator Row and Plus fabric are placed between the stone and the Isolator Row Plus chambers. The woven geotextile provides a media for stormwater filtration, a durable surface for maintenance, prevents scour of the underlying stone and remains intact during high pressure jetting.
The Isolator Row Plus is designed to capture the “first flush” runoff and offers the versatility to be sized on a volume basis or a flow-rate basis. An upstream manhole provides access to the Isolator Row Plus and includes a high/low concept such that stormwater flow rates or volumes that exceed the capacity of the Isolator Row Plus bypass through a manifold to the other chambers. This is achieved with an elevated bypass manifold or a high-flow weir. This creates a differential between the Isolator Row Plus row of chambers and the manifold to the rest of the system, thus allowing for settlement time in the Isolator Row Plus. After Stormwater flows through the Isolator Row Plus and into the rest of the chamber system it is either exfiltrated into the soils below or passed at a controlled rate through an outlet manifold and outlet control structure.
The Isolator Row Plus FlampTM is a flared end ramp apparatus attached to the inlet pipe on the inside of the chamber end cap. The FLAMP provides a smooth transition from pipe invert to fabric bottom. It is configured to improve chamber function performance by enhancing outflow of solid debris that would otherwise collect at the chamber's end, or more difficult to remove and require confined space entry into the chamber area. It also serves to improve the fluid and solid flow into the access pipe during maintenance and cleaning and to guide cleaning and inspection equipment back into the inlet pipe when complete.
The Isolator Row Plus may be part of a treatment train system. The treatment train design and pretreatment device selection by the design engineer is often driven by regulatory requirements. Whether pretreatment is used or not, StormTech recommend using the Isolator Row Plus to minimize maintenance requirements and maintenance costs.
Note: See the StormTech Design Manual for detailed information on designing inlets for a StormTech system, including the Isolator Row Plus.

3 Inspection
The frequency of inspection and maintenance varies
by location. A routine inspection schedule needs to
be established for each individual location based
upon site specific variables. The type of land use
(i.e. industrial, commercial, residential), anticipated pollutant load, percent imperviousness, climate,
etc. all play a critical role in determining the actual frequency of inspection and maintenance practices.
At a minimum, StormTech recommends annual
inspections. Initially, the Isolator Row Plus should
be inspected every 6 months for the first year of
operation. For subsequent years, the inspection
should be adjusted based upon previous observation
of sediment deposition.
The Isolator Row Plus incorporates a combination
of standard manhole(s) and strategically located
inspection ports (as needed). The inspection ports
allow for easy access to the system from the surface,
eliminating the need to perform a confined space
entry for inspection purposes.
If upon visual inspection it is found that sediment
has accumulated, a stadia rod should be inserted to
determine the depth of sediment. When the average
depth of sediment exceeds 3" (75 mm) throughout
the length of the Isolator Row Plus, clean-out should
be performed.
Maintenance
The Isolator Row Plus was designed to reduce the cost
of periodic maintenance. By “isolating” sediments
to just one row, costs are dramatically reduced
by eliminating the need to clean out each row of
the entire storage bed. If inspection indicates the
potential need for maintenance, access is provided
via a manhole(s) located on the end(s) of the row for
cleanout. If entry into the manhole is required, please follow local and OSHA rules for a confined space
entry.
Maintenance is accomplished with the JetVac
process. The JetVac process utilizes a high pressure
water nozzle to propel itself down the Isolator Row
Plus while scouring and suspending sediments.
As the nozzle is retrieved, the captured pollutants
are flushed back into the manhole for vacuuming.
Most sewer and pipe maintenance companies have
vacuum/JetVac combination vehicles. Selection of an
appropriate JetVac nozzle will improve maintenance
efficiency. Fixed nozzles designed for culverts or large diameter pipe cleaning are preferable. Rear facing
jets with an effective spread of at least 45” are best.
StormTech recommends a maximum nozzle pressure
of 2000 psi be utilized during cleaning. JetVac reels
can vary in length. For ease of maintenance, ADS
recommends Isolator Row Plus lengths up to 200'
(61 m). The JetVac process shall only be performed
on StormTech Isolator Row Plus that have ADS
Plus Fabric (as specified by StormTech) over their
angular base stone.

LIFT STATION REQUIRED MAINTENANCE
The lift station should be inspected twice a year for proper operation, and should be checked for overabundance of solid matter such as grease and soap buildup.
Proper operation and inspection would include the following:
1) Automatic operation of the system by float activation. One pump starting at lead on levels, second pump starting at high level conditions; manual operation by use of the selector switches.
2) Inspect floats for proper elevation and for proper movement. Correct any obstructions.
3) Check incoming power for proper voltage. Check voltage at motor connections. 4) Check amperage of each motor.
5) Hose down lift station to clean the walls of the wet well, pumps and floats.
MECHANICAL SEAL INSPECTION OF PUMPS
Inspection of the mechanical seals should be done every two years.
The inspection will include the following:
Pull pump out of wet well. Remove oil seal plug and inspect the oil for clarity. Clear oil indicates no water intrusion and chamber is to be topped off with 30 weight turbine oil.
If oil is cloudy the mechanical seal and oil needs to be replaced.
Note: Your lift station is designed to pump raw unscreened sewage. Refrain from putting the following into your sewage system: tampons, feminine napkins, condoms, handy wipes, baby wipes, paper towels, diapers, plastic bags, q-tips, etc., and food grease. Although grease will be pumped, grease will cause problems eventually and will not be covered under the manufacturer’s warranty. Dispose of the above items in a trash can.
PSI recommends that preventive maintenance and service be performed by a qualified technician.
Any question regarding your lift station should be directed to Scott Richardson at 800- 358-9095.

2.0 PROJECT DESCRIPTION
2.1 Site Location and Background
The irregular-shaped, approximately 4.6-acre site is bounded to the north by Glenwood Drive, to the west by Aliso Creek Road, and to the east and south by existing developments. The site is currently occupied by a commercial building and associated parking.
Historic aerial images are available as far back as 1938 and indicate the site was originally vacant. By 1992, the commercial building was constructed along with associated parking. The site has remained relatively unchanged since (Historic Aerials, 2025).
2.2 Proposed Development
The site will be redeveloped to support a residential development consisting of 58 single-family residential structures and associated improvements. Alta anticipates that conventional cut-and-fill grading techniques will be used to develop the site for the support of wood-frame construction with shallow foundations and reinforced concrete slabs-on-grade, and associated improvements.
3.0 SITE INVESTIGATION AND LABORATORY TESTING
3.1 Subsurface Investigation
Alta conducted a subsurface investigation on August 27th, 2025, consisting of the drilling, logging, and select sampling of four (4) hollow stem auger borings up to a maximum depth of 51.5-feet below the ground surface. The locations of the exploratory borings and excavations are shown on Plate 1 and the logs are presented in Appendix B.
Laboratory testing was performed on bulk samples obtained during the field investigation. A brief description of the laboratory test procedures and the test results are presented in Appendix C.

3.2 Infiltration Testing
It is Alta’s understanding that the project may utilize infiltration systems for storm water disposal. Details of the system are not known at this time.
Infiltration testing was conducted in two (2) boring wells at a depth of 5.0-feet below the ground surface at specified locations. The testing was performed in general conformance with the County of Orange WQMP specifications. The testing wells were presoaked for more than 24 hours prior to testing. During testing, the water level readings were recorded every 10 to 30 minutes until the readings stabilized.
The data was then adjusted to provide an infiltration rate utilizing the Porchet Method. The resulting field infiltration rates, with no factor of safety, are summarized below in Table 3-1.

4.0 GEOLOGIC CONDITIONS
4.1 Geologic and Geomorphic Setting
Regionally, the subject site is located in the Peninsular Ranges geomorphic province, which characterizes the southwest portion of southern California where right-lateral major active fault zones predominately trend northwestsoutheast. The Peninsular Ranges province is composed of plutonic and metamorphic rock, with lesser amounts of Tertiary volcanic and sedimentary rock, Quaternary drainage in-fills and sedimentary veneers. 1890
Project Number 1-0631 Page 4

ALTA CALIFORNIA GEOTECHNICAL, INC.
4.2 Stratigraphy
Based on our literature review and subsurface investigation, the subject site is underlain by the Monterey Formation (CDC, 2001, Figure 1). The geologic unit is briefly described below.
4.2.1 Monterey Formation (map symbol Tmy)
The Miocene-age Monterey Formation observed onsite primarily consists of silty sandstone, clayey sandstone, sandy claystone, sandstone, and claystone. The fine grained silty sandstone onsite is pale brown, white, dark yellowish brown, and brown in a slightly moist to moist and medium dense to very dense condition. The fine grained clayey sandstone onsite is pale brown, white, dark brown, brown, gray, light gray, dark grayish brown, and bluish gray in a slightly moist to moist and medium dense to dense condition. The sandy claystone onsite is dark brown, brown, and gray in a moist and stiff to very stiff condition. The very fine to fine grained sandstone onsite is pale brown, yellowish brown, grayish pale brow, and orange in a slightly moist and medium dense to very dense condition. The claystone onsite is dark brown to brown in a moist and very stiff condition. This unit was logged to a depth of 51.5 feet below the ground surface and is overlain by a thin layer of asphalt.
4.3 Geologic Structure
4.3.1 Tectonic Framework
Jennings (1985) defined eight structural provinces within California that have been classified by predominant regional fault trends and similar fold structure. These provinces are in turn divided into blocks and sub-blocks that are defined by “major Quaternary faults.” These blocks and subblocks exhibit similar structural features. Within this framework, the subject site is located within Structural Province I, which is controlled by 1891

the dominant northwest trend of the San Andreas Fault and is divided into two blocks, the Coast Range Block and the Peninsular Block. The Peninsular Range Block, on which this site is located, is characterized by a series of parallel, northwest trending faults that exhibit right-lateral strike-slip movement. These faults are terminated by the Transverse Range block to the north and extend southward into the Baja Peninsula.
These northwest trending faults divide the Peninsular Range block into eight sub-blocks. The site is located in the northwestern portion of the Santa Ana sub-block, one of the eight sub-blocks, which is bound on the east by the Elsinore fault zone and on the west by the NewportInglewood fault zone.
4.3.2 Regionally Mapped Active Faults
Several large, active fault systems including the Elsinore and NewportInglewood faults occur in the region surrounding the site. These fault systems have been studied extensively and in a large part control the geologic structure of southern California.
4.3.3 Geologic Structure
Based upon our literature review, the younger fan deposits are of Quaternary age and are not folded or faulted.
4.4 Groundwater
Groundwater was not encountered during our subsurface investigation. Based on state-provided information, the historic-high groundwater is greater than
20.0 feet below the ground surface (CGS, 2001). The most recent groundwater data retrieved from the nearest groundwater monitoring site, site ID 336555N1176965W001, was recorded in 2024 and indicates groundwater was approximately greater than 60.0-feet at that time (CDWR, 2025). 1893

4.5 Earthquake Hazards
The subject site is located in southern California, which is a tectonically active area. The type and magnitude of seismic hazards affecting a site are dependent on the distance to the causative fault and the intensity and magnitude of the seismic event. The seismic hazard may be primary, such as surface rupture and/or ground shaking, or secondary, such as liquefaction and/or ground lurching.
4.5.1 Local and Regional Faulting
The site is located in the northwestern portion of the Santa Ana subblock. The closest known active faults and their distances to the site are presented on Table 4-1 below.
TABLE 4-1
Local and Regional Faulting
Fault Zone Distance to Fault Zone
San Joaquin Hills 2.2 miles
Newport-Inglewood 7.1 miles
Elsinore 18.0 miles
Chino 18.4 miles
Palos Verdes 21.7 miles
Puente Hills (Coyote Hills) 22.1 miles
Coronado Bank 24.2 miles
Puente Hills (Santa Fe Springs) 28.6 miles
4.5.2 Surface Rupture
Active faults are not known to exist within the project and a review of Special Publication 42 indicates the site is not within a California State designated earthquake fault zone. Accordingly, the potential for fault surface rupture on the subject site is very low.
1894
Project Number 1-0631 Page 7
September 26, 2025
ALTA CALIFORNIA GEOTECHNICAL, INC.
4.5.3 Seismicity
Ground shaking hazards caused by earthquakes along other active regional faults do exist. The 2022 California Building Code requires usemodified spectral accelerations and velocities for most structural designs.
Seismic design parameters using soil profile types identified in the 2022 California Building Code are presented in Section 7.3.
4.5.4 Landslide Potential
Based on a review of the Seismic Hazard Zone Report for the San Juan Capistrano Quadrangle, the slope superjacent to the site is within an area with landslide potential. Further discussion into this hazard and its effects on the proposed project are presented in Section 6.3.
4.5.5 Liquefaction
Seismic agitation of relatively loose saturated sands, silty sands, and some silts can result in a buildup of pore pressure. If the pore pressure exceeds the overburden stresses, a temporary quick condition known as liquefaction can occur. Liquefaction effects can manifest in several ways including: 1) loss of bearing; 2) lateral spread; 3) dynamic settlement; and 4) flow failure. Lateral spreading has typically been the most damaging mode of failure.
In general, the more recent that a sediment has been deposited, the more likely it will be susceptible to liquefaction. Other factors that must be considered are groundwater, confining stresses, relative density, and the intensity and duration of seismically induced ground shaking.
Based on State provided information, the site is not located within a liquefaction zone. Groundwater was not encountered during our investigation to a depth of 51.5-feet bgs. Based on density of the 1895
Project Number 1-0631 Page 8

underlying formation, it is anticipated that the potential for liquefaction is nil.
5.0 ENGINEERING PROPERTIES AND ANALYSIS
5.1 Materials Properties
Presented herein is a general discussion of the engineering properties of the onsite materials that will be encountered during construction of the proposed project. Descriptions of the soil (Unified Soil Classification System) are presented on the logs in Appendices B.
5.1.1 Excavation Characteristics
Based on the data provided from the subsurface investigation, it is our opinion that the majority of the onsite materials possess favorable excavation characteristics such that conventional equipment can be utilized. Considerations should be given to the high moisture content of the diatomaceous soils encountered, as presented in the boring logs (Appendix B).
5.1.2 Compressibility
The upper portions of the Monterey Formation onsite are considered compressible and unsuitable to support the proposed improvements.
Recommended removal depths are presented in Section 6.1.2.
As noted in the boring logs (Appendix B), the onsite soils are diatomaceous. Considerations should be given to the low dry density and high moisture content.
5.1.3 Hydro-Consolidation
Hydro-consolidation is the effect of introducing water into soil that is prone to collapse. Upon loading and initial wetting, the soil structure and apparent strength are altered resulting in almost immediate settlement. 1896
Project Number 1-0631 Page 9
September 26, 2025
ALTA CALIFORNIA GEOTECHNICAL, INC.
That settlement can have adverse impacts on engineered structures, particularly in areas where it is manifested differentially. Differential settlements are typically associated with differential wetting, irregularities in the subsurface soil conditions, or irregular loading patterns.
Based on laboratory testing (Appendix C), there is minimal potential for hydro-collapse in the Monterey Formation onsite.
5.1.4 Expansion Potential
Expansion index testing was performed on samples taken during our subsurface investigation. Based on laboratory results, it is anticipated that the majority of materials onsite are “low” to “medium” in expansion potential (21≤EI≤90, Appendix C) when tested per ASTM D: 4829.
5.1.5 Earthwork Adjustments
The values presented in Table 5-2 are deemed appropriate for estimating purposes and may be used in an effort to balance earthwork quantities.
As is the case with every project, contingencies should be made to adjust the earthwork balance when grading is in-progress and actual conditions are better defined.

5.1.6 Chemical Analyses
Chemical testing was performed on samples of material underlying the proposed site. Soluble sulfate test results indicate that the soluble sulfate concentrations of the soils tested are classified as negligible (Category S0) per ACI 318-14.
Negligible chloride levels were detected in the onsite soils. Based on laboratory results of soluble sulfate, chloride, and pH testing as presented in Appendix C, the onsite soils are classified as “non-corrosive” to buried metals and concrete (Caltrans, 2022). Additional discussions on corrosion are presented in Section 7.9. Corrosion tests results are presented in Appendix C.
5.2 Engineering Analysis
Presented below is a general discussion of the engineering analysis methods that were utilized to develop the conclusions and recommendations presented in this report.
5.2.1 Bearing Capacity and Lateral Earth Pressures
Ultimate bearing capacity values were obtained using the graphs and formula presented in NAVFAC DM-7.1. Allowable bearing was determined by applying a factor of safety of at least 3 to the ultimate bearing capacity. Static lateral earth pressures were calculated using Rankine methods for active and passive cases. If it is desired to use Coulomb forces, a separate analysis specific to the application can be conducted.

6.0 CONCLUSIONS AND RECOMMENDATIONS
Based on Alta’s findings during our subsurface investigation, the laboratory test results, and our staff’s previous experience in the area, it is Alta’s opinion that the development of the site is feasible from a geotechnical perspective. Presented below are recommendations that should be incorporated into site development and construction plans.
6.1 Remedial Grading Recommendations
All grading shall be accomplished under the observation and testing of the project geotechnical consultant in accordance with the recommendations contained herein and the City of Santa Ana criteria.
6.1.1 Site Preparation
Vegetation, construction debris, and other deleterious materials are unsuitable as structural fill material and should be disposed of offsite prior to commencing grading/construction. Any septic tanks, seepage pits or wells should be abandoned as per the County of Orange Department of Health Services.
Existing concrete should be removed prior to the placement of engineered fill. The demolished concrete may be incorporated into compacted, engineered fills after it is crushed to a maximum size of six (6) inches. Prior to placement as engineered fill any protruding steel rebar should be cut from the concrete pieces and disposed of offsite.
Existing asphaltic concrete should be removed prior to the placement of engineered fill. From a geotechnical perspective, this material may be incorporated into compacted, engineered fills after it is ground down to passing the #4 sieve.
1899
Project Number 1-0631 Page 12
September 26, 2025
ALTA CALIFORNIA GEOTECHNICAL, INC.
6.1.2 Unsuitable Soil Removals
The upper portions of alluvium are compressible and as such, are not suitable to support the proposed structures. Therefore, it is anticipated that, on average, the upper five (5) feet of existing soils will require removal and recompaction, extending a minimum of five (5) feet horizontally outside of the structures. This recommended removal combined with the foundation recommendations presented in Section
7.1 should provide suitable support for the proposed structures.
Footings for structures should be underlain by a minimum of three (3) feet of compacted fill. As such, for building pads where unsuitable soil removals do not provide the minimum depth of compacted fill, or where design grades and/or remedial grading activities create cut/fill transitions, the cut and shallow fill portions of the building pads should be over-excavated during grading and replaced with compacted fill. This condition shall be reviewed as foundation plans become available. The intent of this recommendations if for foundation loads to be encompassed within the engineered fill.
The Project Geotechnical Consultant should observe the removal bottom prior to placing fill. If unsuitable soils such as undocumented artificial fill is exposed upon the completion of the removals recommended above, additional removals may be required.
For fill areas in parking lots/drive aisles, in general, a minimum removal and recompaction of the upper two (2) feet is recommended, however all undocumented artificial fill shall be removed and recompacted. For cuts greater than two (2) feet in street areas, removals are not required. For 1900
Project Number 1-0631 Page 13
September 26, 2025
ALTA CALIFORNIA GEOTECHNICAL, INC.
cuts less than two (2) feet, the two (2) foot removal and recompaction applies.
6.2 General Earthwork Recommendations
6.2.1 Compaction Standards
All fill and processed natural ground shall be compacted to a minimum relative compaction of 90 percent, as determined by ASTM Test Method:
D-1557. Fill material should be moisture conditioned to optimum moisture or above, and as generally discussed in Alta’s Earthwork Specification Section presented in Appendix E. Compaction shall be achieved with the use of heavy earthwork equipment. Mixing and moisture conditioning will be required in order to achieve the recommended moisture conditions.
As noted in the boring logs (Appendix B), the onsite soils are diatomaceous. Considerations should be given to the low dry density and high moisture content. It is recommended to utilize a contractor familiar with the difficulty of conducting grading operations within diatomaceous soil. Slower production rates should be anticipated.
6.2.2 Groundwater/Seepage
Groundwater was not encountered during the subsurface investigation. It is not anticipated that groundwater will be encountered during construction. It is possible that perched groundwater conditions could be encountered depending on the time of year construction occurs.
6.2.3 Documentation of Removals
All removal/over-excavation bottoms should be observed and approved by the project Geotechnical Consultant prior to fill placement.
Consideration should be given to surveying the removal bottoms and undercuts after approval by the geotechnical consultant and prior to the 1901
Project Number 1-0631 Page 14
September 26, 2025
ALTA CALIFORNIA GEOTECHNICAL, INC.
placement of fill. Staking should be provided in order to verify undercut locations and depths.
6.2.4 Treatment of Removal Bottoms
At the completion of removals/over-excavation, the exposed removal bottom should be ripped to a minimum depth of eight (8) inches, moisture-conditioned to above optimum moisture content and compacted in-place to the project standards.
6.2.5 Fill Placement
After removals, scarification, and compaction of in-place materials are completed, additional fill may be placed. Fill should be placed in eightinch bulk maximum lifts, moisture conditioned or dried back so as to achieve optimum moisture content or above, compacted and tested as grading progresses until final grades are attained.
6.2.6 Mixing
Mixing of materials may be necessary to prevent layering of different soil types and/or different moisture contents. The mixing should be accomplished prior to and as part of compaction of each fill lift.
6.2.7 Import Soils
Import soils, if necessary, should consist of clean, structural quality, compactable materials similar to the on-site soils and should be free of trash, debris, or other objectionable materials. The project Geotechnical Consultant should be notified not less than 72 hours in advance of the locations of any soils proposed for import. Import sources should be sampled, tested, and approved by the project Geotechnical Consultant at the source prior to the importation of the soils to the site. The project Civil Engineer should include these requirements on plans and specifications for the project.
1902
Project Number 1-0631 Page 15
September 26, 2025
ALTA CALIFORNIA GEOTECHNICAL, INC.
6.2.8 Utility Trenches
6.2.8.1 Excavation
Utility trenches should be supported, either by laying back excavations or shoring, in accordance with applicable OSHA standards. In general, existing site soils are classified as Soil Type “B” and "C" per OSHA standards. Upon completion of the recommended removals and recompaction, the artificial fill will be classified as Soil Type "B". The Project
Geotechnical Consulting should be consulted if geologic conditions vary from what is presented in this report.
6.2.8.2 Backfill
Trench backfill should be compacted to at least 90 percent of maximum dry density as determined by ASTM D-1557.
Onsite soils will not be suitable for use as bedding material but will be suitable for use in backfill provided oversized materials are removed. Although suitable for backfill,
consideration should be given to utilizing imported materials as backfill materials. If native soils are to be used, slower production rates should be anticipated. No surcharge loads should be imposed above excavations. This includes spoil piles, lumber, concrete trucks, or other construction
materials and equipment. Drainage above excavations
should be directed away from the banks. Care should be
taken to avoid saturation of the soils. Compaction should be accomplished by mechanical means. Jetting of native soils will not be acceptable.
1903
Project Number 1-0631 Page 16
September 26, 2025
ALTA CALIFORNIA GEOTECHNICAL, INC.
Under-slab trenches should also be compacted to project specifications. If select granular backfill (SE > 30) is used, compaction by flooding will be acceptable.
6.3 Slope Stability
Surrounding the western and northern boundary of the site, adjacent to Glenwood Drive and Aliso Creek Road, is an approximately 50 foot slope ascending from the site. Within this slope is a landslide hazard mapped by the California Department of Conservation (CDMG, 2001). Based on a review of available data, the construction of the slope was completed during the grading of the existing structures or adjacent streets. Reports pertaining to this grading and any geologic / geotechnical reports pertaining to the hazard are not available from the City or the County. No visible instabilities were observed during our investigation. V-ditches are currently in place, and the existing slope is planted.
In consideration of the existing slope, the proposed structures have been setback from the toe of the slope in accordance with the requirements of the CBC.
Further review should be done as the project progresses. Additional recommendations pertaining to the grading and mitigation of the mapped hazard may be required based on conditions exposed during grading.
7.0 DESIGN CONSIDERATIONS
7.1 Structural Design
It is anticipated that multi-story residential structures with slab on-grade and shallow foundations will be constructed. Upon the completion of rough grading, finish grade samples should be collected and tested in order to provide specific recommendations as they relate to the individual building pads. These test 1904
Project Number 1-0631 Page 17
September 26, 2025
ALTA CALIFORNIA GEOTECHNICAL, INC.
results and corresponding design recommendations should be presented in a final rough grading report. Final slab and foundation design recommendations should be made based upon specific structure sitings, loading conditions, and asgraded soil conditions.
It is anticipated that the majority of onsite soils will possess “low” to “medium” expansion potential when tested in general accordance with ASTM Test Method D: 4829. Due to the inherent characteristics of diatomaceous soils, it is recommended to utilize post-tensioned foundations in the design of the project.
7.1.1 Foundation Design
Foundations may be preliminary designed based on the values presented in Table 7-1 below.
Table 7-1
Foundation Design Parameters*
Allowable Bearing 1500 lbs/ft2 (assuming a minimum embedment depth and width of 12 inches)

Settlement Static Settlement – 0.5 inch in 40 feet
Dynamic Settlement – 0.5 inch in 40 feet
*These values may be increased as allowed by Code to resist transient loads such as wind or seismic. Building code and structural design considerations may govern depth and reinforcement requirements and should be evaluated.
7.1.2 Post-Tensioning Slabs/Foundation Design Recommendations Post-tensioned slabs for the project may be designed utilizing the parameters presented in Tables 7-1 and 7-2. The parameters presented herein are based on methodology provided in the Design of PostTensioned Slabs-On-Ground, Third Edition, by the Post-Tensioning Institute, in accordance with the 2022 CBC.

A moisture barrier should be provided in accordance with the recommendations presented in Section 7.2 The parameters presented herein are based on procedures presented in the Design of Post-Tensioned Slabs-OnGround, Third Edition. No corrections for vertical barriers at the edge of the slab, or for adjacent vegetation have been assumed. The design parameters are based on a Constant Suction Value of 3.9 pF.
7.2 Moisture Barrier
A moisture and vapor retarding system should be placed below the slabs-ongrade in portions of the structure considered to be moisture sensitive and should be capable of effectively preventing the migration of water and reducing the transmission of water vapor to acceptable levels. Historically, a 10-mil plastic membrane, such as Visqueen, placed between two to four inches of clean sand, has been used for this purpose. The use of this system or other systems can be considered, at the discretion of the designer, provided the system reduces the vapor transmission rates to acceptable levels.

7.3 Seismic Design
The site classes were determined based on the referenced reports and published geologic maps in the area in general conformance with Chapter 20 of ASCE 7-16.
Based on the density of the underlying soils, a Site Class of D (shear wave velocity of 259 m/s) was selected. The seismic design parameters were calculated using a program based on the USGS website and ASCE 7-16 procedures. The resulting values are presented in Table 7-3. These values are applicable providing the exceptions presented in Supplements 2 and 3 of ASCE 7- 16 are utilized in the design of the structure. If the design does not include the exception methodology, then a site-specific analysis shall be conducted.

7.4 Fence and Garden Walls
Block walls, if used, should be embedded a minimum of 2 feet below the lowest adjacent grade. Construction joints (not more than 20 feet apart) should be included in the block wall construction. Side yard walls should be structurally separated from the rear yard wall.
7.5 Footing Excavations
Soils from the footing excavations should not be placed in slab-on-grade areas unless properly compacted and tested. The excavations should be cleaned of all loose/sloughed materials and be neatly trimmed at the time of concrete placement. The Project Geotechnical Consultant should observe the footing excavations prior to the placement of concrete to determine that the excavations are founded in suitably compacted material.
7.6 Retaining Walls
Retaining walls should be founded on engineered fill and should be backfilled with granular soils that allow for drainage behind the wall. Foundations may be designed in accordance with the recommendations presented in Table 7-1, above. Unrestrained walls, free to horizontally move 0.0005H (for dense cohesionless backfill), may be designed to resist lateral pressures imposed by a fluid with a unit weight determined in accordance with the Table 7-4 below. The table also presents design parameters for restrained (at-rest) retaining walls.
These parameters may be used to design retaining walls that may be considered as restrained due to the method of construction or location (corner sections of unrestrained retaining walls).

Per the requirements of the 2022 CBC, the seismic force acting on the retaining walls with backfill exceeding 6-feet in height may be resolved utilizing the formula 12.5H2 lb/lineal ft (H=height of the wall). This force acts at approximately 0.6H above the base of the wall. The seismic value can be converted as required by the retaining wall engineer. Retaining walls should be designed in general accordance with Section 1807A.2 of the 2022 CBC. Restrained retaining walls should be designed for “at-rest” conditions. The design loads presented in the above table are to be applied on the retaining wall in a horizontal fashion and as such friction between wall and retained soils should not be allowed in the retaining wall analyses. Additional allowances should be made in the retaining wall design to account for the influence of construction loads, temporary loads, and possible nearby structural footing loads.
Select backfill should be granular, structural quality backfill with a Sand Equivalent of 20 or better and an ASCE Expansion Index of 20 or less. The backfill must encompass the full active wedge area. The upper one foot of backfill should be comprised of native on-site soils (see Plate A). The wall design should include waterproofing (where appropriate) and backdrains or weep holes for relieving possible hydrostatic pressures. The backdrain should be comprised of a 4-inch perforated PVC pipe in a 1 ft. by 1 ft., ¾-inch gravel matrix, wrapped with a geofabric. The backdrain should be installed with a minimum gradient of 2 percent and should be outletted to an appropriate location. For subterranean walls this may include drainage by sump pumps.
No backfill should be placed against concrete until minimum design strengths are achieved.
It should be noted that the allowable bearing and lateral bearing values presented in Table 7-1 are based on level conditions at the toe. Modified design parameters can be presented for retaining walls with sloping condition at the toe. Other conditions should be evaluated on a case-by-case basis. 1909

7.7 Exterior Slabs and Walkways
Exterior concrete slabs and walkways should be designed and constructed in consideration of the following recommendations.
7.7.1 Subgrade Compaction
The subgrade below exterior concrete slabs should be compacted to a minimum of 90 percent relative compaction as determined by ASTM Test Method: D 1557.
7.7.2 Subgrade Moisture
The subgrade below concrete slabs should be moisture conditioned to a minimum of 110 percent (low expansion potential) or 120 percent (medium expansion potential) of optimum moisture prior to concrete placement
7.7.3 Concrete Slab Thickness
Concrete flatwork and driveways should be designed utilizing four-inch minimum thickness.
7.7.4 Concrete Slab Reinforcement
Utilization of reinforcement for flatwork and driveways is subject to a cost/benefit analysis. Reinforcement will decrease the amount of cracking that may occur in flatwork, however, planning for occasional repairs may be more cost effective. Utilizing closely spaced control joints is likely more cost-effective than utilizing reinforcement. The majority of the soils onsite are classified as very low in expansion potential.
Consideration should be given to reinforcing flatwork with irregular (nonsquare/rectangular) shapes or flatwork underlain by medium expansive soils. Reinforcement may consist of 6x6 W.14/W1.4 welded wire mesh or an equivalent section of rebar.
1911
Project Number 1-0631 Page 23
September 26, 2025
ALTA CALIFORNIA GEOTECHNICAL, INC.
7.7.5 Control Joints
Weakened plane joints should be installed on walkways at intervals of approximately eight feet (maximum) or less. Exterior slabs should be designed to withstand shrinkage of the concrete.
7.8 Concrete Design
As stated in Section 5.1.7, negligible concentrations of sulfates were detected in the onsite soils (Class S0). Therefore, the use of sulfate resistant concrete is not required per ACI 318-14 at this time. Post-grading conditions should be evaluated, and final recommendations made at that time.
7.9 Corrosion
Based on laboratory results of soluble sulfate, chloride, and pH testing as presented in Appendix C, the onsite soils are classified as “non-corrosive” to buried metals and concrete (Caltrans, 2022). Buried ferrous metals should be protected against the effects of corrosive soils in accordance with the manufacturer’s recommendations. Typical measures may include using noncorrosive backfill, protective coatings, wrapping, plastic pipes, or a combination of these methods. A corrosion engineer should be consulted if specific design recommendations are required by the improvement designer.
Per ACI 318-14, an exposure class of C1 would be applicable to metals encased in concrete (rebar in footings) due to being exposed to moisture from surrounding soils. Per Table 19.3.2.1 of ACI 318-14, the requirements for concrete with an exposure class of C1 are a minimum compressive strength of 2500 psi and a maximum water-soluble chloride ion content in concrete of 0.30 (percent by weight of cement).

7.10 Pavement Design
Pavement sections for the proposed streets shall be designed based on laboratory testing conducted on samples taken from the soil subgrade.
Preliminarily, based on an assumed R-Value of 30, the pavement may be designed utilizing the sections presented in Table 7-5. These sections should be verified upon the completion of grading, based on R-Value testing. The ultimate pavement section design for public streets is under the City of Aliso Viejo’s purview.

5.5 3-inch AC on 7-inch AB 4-inch AC on 5-inch AB
AC-Asphalt Concrete
AB-Caltrans Class II Base
Construction of the streets should be accomplished in accordance with the current criteria of the City of Aliso Viejo. Prior to the placement of base material, the subgrade should be suitably moisture conditioned, processed and compacted to a minimum 95 percent of the laboratory maximum density (ASTM:
D 1557) to at least twelve (12) inches below subgrade. After subgrade compaction, the exposed grade should then be "proof"-rolled with heavy equipment to ensure the grade does not "pump" and is verified as non-yielding.
Aggregate base material should be placed on the compacted subgrade and compacted in-place to a minimum 95 percent of the laboratory standard obtained per ASTM: D 1557.

8.0 LOT MAINTENANCE
Ongoing maintenance of the improvements is essential to the long-term performance of structures. As such, the owners must implement certain maintenance procedures. The attached " Maintenance and Improvement Considerations" presented in the Appendix E may be included as part of the sales packet to educate the owners in issues related to drainage, maintenance, improvements, etc. The following recommendations should also be implemented.
8.1 Lot Drainage
Roof, pad, and lot drainage should be collected and directed away from structures and slopes and toward approved disposal areas. Design fine grade elevations should be maintained throughout the life of the structure or if design fine grade elevations are altered, adequate area drains should be installed in order to provide rapid discharge of water, away from structures and slopes.
Residents should be made aware that they are responsible for maintenance and cleaning of all drainage terraces, down drains, and other devices that have been installed to promote structure and slope stability.
8.2 Burrowing Animals
Owners should undertake a program for the elimination of burrowing animals.
9.0 FUTURE PLAN REVIEWS
This report represents a geotechnical review of the site. As the project design for the project progresses, site specific geologic and geotechnical issues should be considered in the design and construction of the project. Consequently, future plan reviews may be necessary. These reviews may include reviews of:
Grading Plans
Foundation Plans
Utility Plans
These plans should be forwarded to the project Geotechnical Consultant for review. 1914

ALTA CALIFORNIA GEOTECHNICAL, INC.
LABORATORY TESTING
The following laboratory tests were performed on a representative sample in accordance with the applicable latest standards or methods from the ASTM, California Building Code (CBC) and California Department of Transportation.
Classification
Soils were classified with respect to the Unified Soil Classification System (USCS) in accordance with ASTM D-2487 and D-2488.
Particle Size Analysis
Modified hydrometer testing was conducted to aid in classification of the soil. The results of the particle size analysis are presented in Table C.
Maximum Density/Optimum Moisture
The maximum dry density and optimum moisture content of two representative bulk samples were evaluated in accordance with ASTM D-1557. The results are summarized in Table C.
Expansion Index Tests
Two (2) expansion index test was performed to evaluate the expansion potential of typical onsite soil. Testing was carried out in general conformance with ASTM Test Method D-4829. The results are presented in Table C.
Chemical Analyses
Chemical testing was performed on two select samples by Alta. The results of these tests (sulfate content, resistivity, chloride content and pH) are presented on Table C.
Consolidation Tests
Consolidation testing was performed on four (4) relatively “undisturbed” soil samples at their natural moisture content in accordance with procedures outlined in ASTM D-2435. The samples were placed in a consolidometer and loads were applied incrementally in geometric progression. The samples (2.42-inches in diameter and 1-inch in height) were permitted to 1931

Maintenance and Improvement Considerations
1938
Project Number 1-0631 Page D-1
September 26, 2025
ALTA CALIFORNIA GEOTECHNICAL, INC.
MAINTENANCE AND IMPROVEMENT CONSIDERATIONS
General
Owners purchasing property must assume a certain degree of responsibility for improvements and for maintaining conditions around their home. Of primary importance from a geotechnical standpoint are maintaining drainage patterns and minimizing the soil moisture variation below all improvements. Such design, construction and owner maintenance provisions may include:
Employing contractors for improvements who design and build in recognition of local building codes and specific site soils conditions.
Establishing and maintaining positive drainage away from all foundations, walkways, driveways, patios, and other improvements.
Avoiding the construction of planters adjacent to structural improvements.
Alternatively, planter sides/bottoms can be sealed with an impermeable membrane and drained away from the improvements via subdrains into approved disposal areas. Sealing and maintaining construction/control joints within concrete slabs and walkways to reduce the potential for moisture infiltration into the subgrade soils. Utilizing landscaping schemes with vegetation that requires minimal watering. Watering should be done in a uniform manner, as equally as possible on all sides of the foundation, keeping the soil "moist" but not allowing the soil to become saturated. Maintaining positive drainage away from structures and providing roof gutters on all structures with downspouts that are designed to carry roof runoff directly into area drains or discharged well away from the foundation areas. Avoiding the placement of trees closer to the proposed structures than a distance of one-half the mature height of the tree.
Observation of the soil conditions around the perimeter of the structure during extremely hot/dry or unusually wet weather conditions so that modifications can be made in irrigation programs to maintain relatively uniform moisture conditions.
1939
Project Number 1-0631 Page D-2
September 26, 2025
ALTA CALIFORNIA GEOTECHNICAL, INC.
Sulfates
Owners should be cautioned against the import and use of certain inorganic fertilizers, soil amendments, and/or other soils from offsite sources in the absence of specific information relating to their chemical composition. Some fertilizers have been known to leach sulfate compounds into soils and increase the sulfate concentrations to potentially detrimental levels.
Site Drainage
The owners should be made aware of the potential problems that may develop when drainage is altered through construction of hardscape improvements. Ponded water, drainage over the slope face, leaking irrigation systems, overwatering, or other conditions which could lead to ground saturation must be avoided. No water should be allowed to flow over the slopes. No alteration of pad gradients should be allowed that would prevent pad and roof runoff from being directed to approved disposal areas.
Drainage patterns have been established at the time of the fine grading should be maintained throughout the life of the structure. No alterations to these drainage patterns should be made unless designed by qualified professionals in compliance with local code requirements and site-specific soils conditions.
Slope Drainage
Residents should be made aware of the importance of maintaining and cleaning all interceptor ditches, drainage terraces, down drains, and any other drainage devices, which have been installed to promote slope stability.
Subsurface drainage pipe outlets may protrude through slope surfaces and/or wall faces. These pipes, in conjunction with the graded features, are essential to slope and wall stability and must be protected in-place. They should not be altered or damaged in any way.
Planting and Irrigation of Slopes
Seeding and planting of the slopes should be planned to achieve, as rapidly as possible, a well-established and deep-rooted vegetal cover requiring minimal watering. It is the responsibility of the landscape architect to provide such plants initially and of the residents to maintain such planting. Alteration of such a planting scheme is at the resident's risk.
The resident is responsible for proper irrigation and for maintenance and repair of properly installed irrigation systems. Leaks should be fixed immediately. 1940
Project Number 1-0631 Page D-3
September 26, 2025
ALTA CALIFORNIA GEOTECHNICAL, INC.
Sprinklers should be adjusted to provide maximum uniform coverage with a minimum of water usage and overlap. Overwatering with consequent wasteful runoff and serious ground saturation must be avoided.
If automatic sprinkler systems are installed, their use must be adjusted to account for seasonal and natural rainfall conditions.
Burrowing Animals
Residents must undertake a program to eliminate burrowing animals. This must be an ongoing program in order to promote slope stability.
Owner Improvement
Owner improvements (pools, spas, patio slabs, retaining walls, planters, etc.) should be designed to account for the terrain of the project, as well as expansive soil conditions and chemical characteristics. Design considerations on any given lot may need to include provisions for differential bearing materials, ascending/descending slope conditions, bedrock structure, perched (irrigation) water, special geologic surcharge loading conditions, expansive soil stresses, and long-term creep/settlement.
All owner improvements should be designed and constructed by qualified professionals utilizing appropriate design methodologies, which account for the on-site soils and geologic conditions.
Each lot and proposed improvement should be evaluated on an individual basis.
Setback Zones
Manufactured slopes maybe subject to long-term settlement and creep that can manifest itself in the form of both horizontal and vertical movement. These movements typically are produced as a result of weathering, erosion, gravity forces, and other natural phenomenon. A setback adjacent to slopes is required by most building codes, including the California Building Code. This zone is intended to locate and support the residential structures away from these slopes and onto soils that are not subject to the potential adverse effects of these natural phenomena.
The owner may wish to construct patios, walls, walkways, planters, swimming pools, spas, etc. within this zone. Such facilities may be sensitive to settlement and creep and should not be 1941
Project Number 1-0631 Page D-4

ALTA CALIFORNIA GEOTECHNICAL, INC.
constructed within the setback zone unless properly engineered. It is suggested that plans for such improvements be designed by a professional engineer who is familiar with grading ordinances and design and construction requirements. In addition, we recommend that the designer and contractor familiarize themselves with the site specific geologic and geotechnical conditions on the specific lot.
