Hello,
The Los Angeles Regional Board has reviewed its files and has concluded that it does not have any records that are responsive to your request.

The Groundwater Permitting & Land Disposal Unit did note, however, that the properties located at 723, 731, 755, 715, 740, and 726 East Route 66, Glendora, CA 91740, 531 and 540 S Glenwood Ave, Glendora, CA 91740 are in the vicinity of the “Walnut Street - Glendora (508 East Walnut Street, Glendora, CA 91741; 34.131540, -117.853367)” legacy disposal site. The Regional Board has never had an active file and/or records for this legacy site. We suggest contacting the County of Los Angeles Department of Public Health at (626) 430-5540 for any information they may have regarding the legacy land treatment unit(s).

(APN:8646-029-009, 8646- 029-014). The site is bounded by E. Route 66 to the south, A.T. & S.F. Railroad to the north, commercial buildings to the east and west.

According to the federal Emergency Management Agency (FEMA) FIRM rate map number 06037C1440F, effective date September 26, 2008, the site is located within flood Zone X, area of minimal flood hazard.

Refer to Appendix A for additional information.

III. Existing Conditions
The site is currently a vacant auto center building structure with a paved covered lot area. The perimeter of the site is bounded by block walls and chain linked fencing. Vegetation within the site is minimal per geographic observation matching its commercial land use.

The existing drainage condition of the site generally surface sheet flows south-westerly towards E. Route 66 with elevations ranging between approximately 785.5 and 777.6 feet above mean sea level. There is no offsite stormwater run-on due to perimeter control with existing walls along the boundary of the site. Adjacent properties’ drainage slopes away from the proposed site. The outflow of the proposed site continues westerly downstream along E. Route 66 eventually enters existing Los Angeles County Flood Control District’s (LACFCD) catch basin inlets at S. Pasadena Avenue. The runoff continues through LACFCD’s 54-inch reinforced concrete pipe to Big Dalton Wash. All flow ultimately discharges to the San Gabriel River which drains to the Pacific Ocean at San Pedro Bay.

Refer Appendix A.1 for the Preliminary Existing Conditions Hydrology Map.

IV. Proposed Conditions
The project proposes the construction of six (6) residential buildings consisting of thirty-nine (39) dwelling units with private garages, private drive aisles, sidewalks, and common landscaped areas.

The project site will be accessible with an entrance/ exit along E. Route 66. Drive aisles and parking areas will be composed of asphalt concrete pavement. Proposed development imperviousness is assumed to be 86% per Los Angeles County Hydrology Manual’s Appendix D Proportion Impervious Data value based on the development type “Medium-Rise Apartments and condominiums”.

The onsite residential development drainage management area is analyzed as a single subarea as design stormwater mitigation intends to be routed to a single outlet at the south-west corner of the site. There are three (3) onsite inlets that collect and direct runoffs into the proposed interconnected underground infiltration / detention system for water quality treatment sized for the 85th percentile rain event in conformance with water quality treatment standards.

During the design storm event when the infiltration/ detention system reaches full capacity, excess runoff is routed to the parkway drain connection to the public right of way. In cases of a larger storm event beyond the design storm, runoff will pond at the localized inlets and the grading design ensures runoff overflow towards E. Route 66 following historical drainage pattern.

Refer to Appendix A.2 for the Preliminary Post-Development Hydrology Map.

A separate Preliminary LID plan is prepared to address the Los Angeles County storm water quality requirements.

V. Methodology
The project site’s drainage was analyzed per the Los Angeles County Hydrology Manual dated January 2006. The existing and proposed conditions of the site were analyzed for peak flow rate and time of concentration for the 25- and 100- storm events based on acreage, flow path and land cover per La County Department of Public Works (LACDPW) HydroCalc Calculator, Version

1.0.3, released 2/21/2018.

VI. Design Assumption

1. The LACDPW HydroCalc Calculator Program was used to determine Tc, Peak run-off flow rate, and run-off volume for subarea based on the longest flow path and elevation difference.

2. The project site is located in the “Glendora” rainfall region per Los Angeles County Hydrology Map. A depth of 7.45 inches of rainfall was determined from the 50-year storm 24-hour isohyet map, 1-H1.32 in Appendix A.3.

3. The site is in the soil classification of “007” per Los Angeles County Hydrology Map.

4. Existing conditions are assumed to be approximately 99% impervious based on geographic observation which also matches the commercial land use recommended values for existing development type per Hydrology Manual.

5. Proposed conditions are assumed to be approximately 86% impervious based on the recommended values for proposed development type per Hydrology Manual. Additional impervious analysis based on final landscape plan may be re-evaluated during final engineering.

6. Proposed conditions will be directed to public right of way via parkway drain following historical drainage pattern. Therefore, proposed peak flow mitigation will be governed by the existing conditions peak flow.

7. Proposed storm drains will be sized to convey the 100-year storm per urban flood requirement.

VII. Hydrology Analysis
Hydrology Summary
Proposed storm drainage is designed to maintain the single drainage areas prior to the parkway drain outlet connection at the public right of way. A summary of the project site proposed conditions peak runoff values for the drainage management area (DMA) of the project site is provided below:

Existing Conditions
Drainage Area Area (ac) Q25 (cfs) Q100 (cfs)
DMA-XA-1 1.845 6.49 8.29
Proposed Conditions
Drainage Area Area (ac) Q25 (cfs) Q100 (cfs)
DMA-A-1 1.845 5.79 8.18
Refer to Appendix B of this report for additional information and LACDPW HydroCalc output data.

Drainage area may further be delineated into additional subareas per inlets as it drains toward the interconnected detention/infiltration system prior to be routed downstream towards the parkway outlet during final engineering.

Detention Sizing/ Routing Analysis
As the proposed conditions of the site generate a lower runoff peak flowrate compared to the existing peak flow, it was determined that detention will not be necessary for hydrologic mitigation. However, an infiltration/ detention system is provided per water quality treatment requirement. The infiltration rate will further benefit in reducing peak runoff as the site generated runoff peak flow is detained and routes through the onsite storm drainage system. Refer to summary of detention sizing below:

VIII. Hydraulics Analysis
Pipe Sizing/ Parkway Outlet
Preliminary onsite storm drain piping is sized for the 25-year storm event based on open channel flow with assumption of 1% slope; therefore, WSPG hydraulic pressure analysis is not warranted. Pipe Analysis will be re-evaluated during final engineering in coordination with final engineering plan.

Preliminary pipe sizing was done using Hydraflow Express Tool shown within Appendix D.

Preliminary parkway outflow capacity sizing for 100-year storm event to ensure proper outflow is provided within Appendix D.
*A Manning’s Roughness Coefficient of 0.013 has been utilized to represent the roughness coefficient of PVC and/or HDPE piping.

Catch Basin Inlet Sizing
Catch Basin inlet will be sized with a capacity based on the 25-year storm event to conform with LACDPW Hydrology urban flood street capacity.

Analysis is to be provided during final engineering per final grading plan. 100-Year Water Surface Elevation (WSE)
The elevations of the 100-year storm event water surface are analyzed at local collection points to determine the proper flood protection of the buildings. Building finished floors are to be set above the 100-year storm event water surface elevation or proper overflow mitigation is provided where storm runoff continues downstream contained within the street capacity to ensure buildings are not susceptible to flooding.

Analysis is to be provided during final engineering per final grading plan.

IX. Conclusion
The results from the hydrologic analysis demonstrate that the overall proposed development conditions will generate a lower peak runoff flowrate than existing conditions outflow for the project site; therefore, a detention system is not required to detain the generated runoff. However, an infiltration/ detention system is proposed per water quality treatment requirement which will further improve downstream runoff capacity. The impervious area will be verified with the final site plan during final engineering to validate the water quality treatment detention volume.

During the design storm event when the infiltration/ detention system reaches full capacity, excess runoff is routed to the proposed parkway connection to the public right of way. In cases of a larger storm event beyond the design storm, runoff will pond at the localized inlets and the site is graded to overflow towards E. Route 66 following historical drainage pattern.

1.3 Report Limitations
The conclusions and recommendations presented in this report are based on the field and laboratory information generated during this investigation, and a review of the referenced reports. The information contained in this report is intended to be used for development of grading plans and preliminary construction cost estimates.

2.0 PROJECT DESCRIPTION

2.1 Site Location and Existing Conditions
The rectangular shaped approximately ±1.8‐acre, site is relatively flat and consists of a paved parking lot, a dirt field, and a single commercial structure with associated concrete flatwork. The dirt field has remnants of previously placed asphaltic concrete, however, much has been eroded away. The site is bounded to the north by a railroad easement, to the east and west by commercial properties, and to the south by Route 66.

Historic aerial images are available as far back as 1948 and indicate that the site was originally utilized for agricultural purposes. By 1964, the site was cleared and three structures were constructed, one in the southwest corner of the property and two in the southeast corner of the property. The southwestern structure was expanded to its current configuration and the two southeastern structures were demolished by 1974. The dirt field was paved with asphaltic concrete by 1980 and the site has remained largely unchanged since. (Historic Aerials, 2023).

2.2 Proposed Development
It is our understanding that the site is to be developed to support multifamily residential structures and associated improvements. It is Alta’s understanding that conventional cut‐and‐fill grading techniques will be used to develop the site for the support of wood‐frame and stucco construction with shallow foundations and reinforced concrete slabs‐on‐grade, and associated improvements.

3.0 SITE INVESTIGATION

3.1 Subsurface Investigation and Laboratory Testing
Alta conducted a subsurface investigation on May 24th, 2023, consisting of the excavation, logging, and select sampling of four (4) hollow‐stem auger borings to a maximum depth of 26‐feet below the existing ground surface. The locations of the borings are shown on Plate 1 and the boring logs are presented in Appendix B.

Laboratory testing was performed on bulk and ring 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 site may utilize infiltration systems for storm water disposal. Details of the systems are not known at this time.

Infiltration testing was undertaken using two ten (10) foot‐deep borings (P‐1 and P‐2) as shown on Plate 1. The testing was performed on May 25, 2023 in general conformance with the County of Los Angeles Technical Guidance Document Standards. The test wells were presoaked for 24 hours, and then water level readings were recorded every 10 minutes until the readings stabilized.

The data was then adjusted to provide an infiltration rate utilizing the Porchet Method. The resulting infiltration rate is presented in Table 3‐1. The results do not include a Factor of Safety. Recommendations for infiltration BMP design are presented in Section 6.3.

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 major right lateral 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.

4.2 Stratigraphy
Based on our literature review and subsurface investigation the site is underlain by undocumented artificial fill and young alluvial fan deposits. These geologic units are briefly described below.

4.2.1 Undocumented Artificial Fill (Map symbol afu)
The undocumented artificial fill encountered at the site consists primarily of tannish brown and brown silty sand and gravelly sand in a slightly moist and medium dense condition. The unit was logged to depths ranging from two and a half (2.5) to five (5) feet below the ground surface.

Project Number 1‐0486 Page 5
June 22, 2023
ALTA CALIFORNIA GEOTECHNICAL, INC.

4.2.2 Young Alluvial Fan Deposits (Map symbol Qyf)
The artificial fill is underlain by young alluvial fan deposits consisting of brown and dark brown to reddish brown and orange brown gravelly sand and silty sand/clayey sand in a dry to slightly moist, medium dense to very dense condition. Gravel/cobble lenses are common. The unit was logged to a depth of 26.0 feet below the ground surface.

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 sub‐ blocks exhibit similar structural features. Within this framework, the site is located within Structural Province I, which is controlled by the dominant northwest trend of the San Andreas Fault and is divided into two blocks, the Coast Range Block, and the Peninsular Range 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 dip‐ slip movement. These faults are terminated by the Transverse Range block to the north and extend southward to the Baja Peninsula. These northwest trending faults divide the Peninsular Range block into eight sub‐blocks. The site is located on the extreme northern portion of the Riverside Sub‐block, one of the eight sub‐blocks, which is bound on the west by the Elsinore fault zone and on the east by the San Jacinto fault zone.

ALTA CALIFORNIA GEOTECHNICAL, INC.

4.3.2 Regionally Mapped Active Faults
Several large, active fault systems including the Sierra Madre, Elsinore‐ Whittier, San Jacinto, and the San Andreas 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 site investigation and literature review, the onsite alluvial sediments are of Holocene age, and are not folded or faulted.

4.4 Groundwater
Our subsurface investigation did not encounter groundwater to the depth of twenty (26) feet below the ground surface. The historic high groundwater depth approximately 100‐feet below the ground surface (CDMG, 1998).

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 nearest known active faults (movement occurring ≤ 11,700 years ago) are the: Sierra Madre fault, San Jose fault, Clamshell‐Sawpit fault, Cucamonga fault, Raymond fault, Chino fault, and Elsinore fault located

1.4, 4.8, 6.6, 7.1, 8.2, 9.1, and 13.0 miles from the site (USGS, 2008).

Project Number 1‐0486 Page 7
June 22, 2023
ALTA CALIFORNIA GEOTECHNICAL, INC.

4.5.2 Seismicity
Ground shaking hazards caused by earthquakes along other active regional faults exist. The 2022 California Building Code requires use‐ modified 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.

4.5.3 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 Rupture Hazard Zone (CGS, 2018).

Accordingly, the potential for fault surface rupture on the subject site is very low.

4.5.4 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.

The site is not within a State‐identified zone of required investigation for liquefaction (CGS, 1999). Groundwater was not encountered during the Item #6. Page 1298

subsurface investigation which extended to a depth of 26 feet. The nearest groundwater well indicates that groundwater is 519‐ft. below the ground surface.

Based on the depth of groundwater, it is our opinion that the potential for liquefaction is minimal at the site.

4.5.5 Dry Sand Settlement
Dry sand settlement is the process of non‐uniform settlement of the ground surface during a seismic event. Based on our subsurface investigation and our removal/recompaction recommendations, the potential for dry sand settlement is anticipated to be low and within foundation design tolerances.

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 boring logs in Appendix B.

5.1.1 Excavation Characteristics
Based on the data provided from the subsurface investigation, it is our opinion that the onsite materials possess favorable excavation characteristics such that conventional earth moving equipment can be utilized. Gravel and cobbles will be encountered during the excavations in the young alluvial fan deposits.

Project Number 1‐0486 Page 9
June 22, 2023
ALTA CALIFORNIA GEOTECHNICAL, INC.

5.1.2 Compressibility
The undocumented artificial fill and upper portions of young alluvial fan deposits onsite are considered compressible and unsuitable to support the proposed improvements. Recommended removal depths are presented in Section 6.1.2.

5.1.3 Moisture
The moisture content of the undocumented artificial fill and young alluvial fan deposits that will require removal and recompaction as discussed in Section 6.1.2 are typically under‐optimum and will require moisture conditioning for compaction.

5.1.4 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.

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 soil type and gravel content of the soils encountered, the potential for hydro‐collapse in the underlying young alluvial fan deposits is minimal and should be within foundation tolerances upon the completion of the recommended unsuitable soil removals.

5.1.5 Expansion Potential
Expansion index testing was performed on samples taken during our subsurface investigation. Based on the results, it is anticipated that the majority of materials onsite are “very low” to “low” in expansion potential (0≤EI≤50, Appendix C) when tested per ASTM D: 4829.

5.1.6 Earthwork Adjustments
The values presented in Table 5‐1 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.

TABLE 5‐1
Earthwork Adjustment Factors
Geologic Unit Adjustment Factor Range Average
Undocumented Artificial Fill/
Young Alluvial Fan Deposits Shrink 6% to 10% 8%

5.1.7 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 (Class S0) per ACI 318‐14.

Negligible chloride levels were detected in the onsite soils. Resistivity testing conducted as part of this investigation, indicates that the soils are “slightly corrosive” to buried metals (per Romanoff, 1989). Additional discussions on corrosion are presented in Section 7.10. 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 Alta’s recommendations that should be incorporated into site development and construction plans.

6.1 General Earthwork 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 Glendora 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 Item #6. Page 1302

or wells should be abandoned as per the County of Los Angeles 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 crushed to a maximum size of six (6) inches. The crushed asphalt should not be placed under residential structures, but rather, it can be placed in approved non‐ residential areas, such as streets, parking areas or open space. These recommendations should be verified by the environmental consultant.

6.1.2 Unsuitable Soil Removals
The artificial fill and the upper portions of the young alluvial fan deposits near the surface are compressible and as such, are not suitable to support the proposed structures. Accordingly, it is recommended to completely remove the undocumented artificial fills and highly weathered portions of the underlying young alluvial fan deposits across the site and as close to the property boundaries as possible.

As such, it is anticipated that, on average, the upper three (3) to five (5) feet of existing soils will require removal and recompaction, extending at a minimum 1:1 projection horizontally outside the structures. This recommended removal combined with the foundation recommendations Item #6. Page 1303

presented in Section 7.1 should provide suitable support for the proposed structures.

The Project Geotechnical Consultant should observe the removal bottom prior to placing fill. If unsuitable soils such as undocumented artificial fill are exposed upon the completion of the removals recommended above, additional removals will be required.

For streets, in general, a minimum removal and recompaction of the upper two (2) feet of soil is recommended, although deeper removals may be required if undocumented fill is exposed at that depth. Removal bottoms in parking lot areas should be tested to determine that the exposed soils have a minimum relative compaction of 85% of the laboratory maximum density (per ASTM test method D‐1557).

Material removed as part of the unsuitable soil removals can be used as artificial fill, provided it is free of deleterious materials.

6.1.3 Over‐excavation of Building Pads
Footings for structures should be underlain by a minimum of two (2) 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 to provide the required depth of fill below the footings.

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 sheepsfoot rollers or similar kneading type equipment.

6.2.2 Groundwater/Seepage
It is anticipated that groundwater will not be encountered during construction. It is possible that perched water 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 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.

Meeting Date: 9/24/2024 / Packet Page #: 1441
Project Number 1‐0486 Page 15
June 22, 2023
ALTA CALIFORNIA GEOTECHNICAL, INC.

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 eight‐ inch bulk maximum lifts, moisture conditioned to optimum moisture content or above, compacted and tested as grading/construction progresses until final grades are attained.

6.2.6 Moisture Content
The moisture content of the upper in‐situ soils is primarily below optimum, as shown on the boring logs in Appendix B. These soils will require moisture conditioning prior to placement as engineered fill.

6.2.7 Mixing
Mixing of materials may be necessary to prevent layering of different soil types and/or different moisture contents. Mixing should be accomplished prior to and as part of the compaction of each fill lift.

6.2.8 Import Soils
Import soils, if necessary, should consist of clean, low expansive, 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.

6.2.9 Utility Trenches

6.2.9.1 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 Types "B" and “C” per OSHA standards. Upon completion of the recommended removals and re‐compaction, 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.

6.2.9.2 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. 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.

Under‐slab trenches should also be compacted to project specifications. If select granular backfill (SE > 30) is used, compaction by flooding will be acceptable.

ALTA CALIFORNIA GEOTECHNICAL, INC.

6.2.10 Backcut Stability
Temporary backcuts, if required during unsuitable soil removals, should be made no steeper than 1:1 without review and approval of the geotechnical consultant. Flatter backcuts may be necessary where geologic conditions dictate and where minimum width dimensions are to be maintained.

Care should be taken during remedial grading operations in order to minimize the risk of failure. Should failure occur, complete removal of the disturbed material will be required.

In consideration of the inherent instability created by temporary construction backcuts for removals, it is imperative that grading schedules are coordinated to minimize the unsupported exposure time of these excavations. Once started, these excavations and subsequent fill operations should be maintained to completion without intervening delays imposed by avoidable circumstances. In cases where five‐day workweeks comprise a normal schedule, grading should be planned to avoid exposing at‐grade or near‐grade excavations through a non‐work weekend. Where improvements may be affected by temporary instability, either on or offsite, further restrictions such as slot cutting, extending workdays, implementing weekend schedules, and/or other requirements considered critical to serving specific circumstances may be imposed.

6.3 Storm Water Infiltration Systems
From a geotechnical perspective, allowing storm water to infiltrate the onsite soil in concentrated areas increases the potential for settlement, liquefaction, and water‐related damage to structures/improvements, such as wet slabs or pumping subgrade, and should be avoided where possible. If infiltration systems are Item #6. Page 1308
Meeting Date: 9/24/2024 / Packet Page #: 1444
Project Number 1‐0486 Page 18
June 22, 2023
ALTA CALIFORNIA GEOTECHNICAL, INC.
required on this site, care should be taken in designing systems that control the storm water as much as possible.

Preliminary infiltration testing was conducted at the site as part of this investigation, and the methodology is discussed in 3.2. The resulting infiltration rates for P‐1 and P‐2 was calculated to be 13.4 and 10.8‐inches per hour, respectively. The results do not include a factor of safety.

Groundwater was not encountered during our investigation to a maximum depth of 26.0 feet below the ground surface. The historic high groundwater depth approximately 100‐feet below the ground surface (CDMG, 1998).

The Project Geotechnical Consultant should review the final WQMP design prior to construction.

6.4 Boundary Conditions
The site is bounded to the north by a railroad easement, to the east and west by commercial properties, and to the south by Route 66. Construction of retaining/screen walls along these boundaries will require additional geotechnical recommendations concerning unsuitable soil removals and foundation design parameters. Boundary conditions for the project should be reviewed by the Project Geotechnical Consultant as the design progresses.

7.0 DESIGN CONSIDERATIONS

7.1 Structural Design
It is anticipated that multi‐story, wood‐frame 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 results and corresponding design recommendations should be presented in a final rough grading report. Final slab and foundation design recommendations Item #6. Page 1309
Meeting Date: 9/24/2024 / Packet Page #: 1445

should be made based upon specific structure sitings, loading conditions, and as‐ graded soil conditions.

It is anticipated that the majority of onsite soils will possess “very low” to “low” expansion potential when tested in general accordance with ASTM Test Method D: 4829. For budgeting purposes, the following foundation design requirements for a range of potential expansion characteristics are presented.

7.1.1 Foundations
Foundations may be preliminary designed based on the values presented in Table 7‐1 below.

Table 7‐1
Foundation Design Parameters*
Allowable Bearing 2000 lbs/ft2 assuming a minimum footing width and embedment of 12 inches.

*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 Conventional Slab/Foundation Systems
Based on the onsite soils conditions and information supplied by the 2022 CBC, conventional slab/foundation systems may be designed in accordance with Tables 7‐1 and 7‐2.

If exterior footings adjacent to drainage swales are to exist within five (5) feet horizontally of the swale, the footing should be embedded sufficiently to assure embedment below the swale bottom is maintained. Footings adjacent to slopes should be embedded such that at least five‐ (5) feet is provided horizontally from edge of the footing to the face of the slope.

7.1.3 Post‐Tensioned Slabs/Foundation Design Recommendations Post‐tensioned slabs for the project may be preliminarily designed utilizing the parameters presented in Tables 7‐1 and 7‐3. The parameters presented herein are based on methodology provided in the Design of Post‐Tensioned Slabs‐On‐Ground, Third Edition, by the Post‐Tensioning Institute, in accordance with the 2022 CBC.

The minimum outer footing embedment presented herein are based on expansion indexes. The structural engineer should verify the minimum embedment based on the number of floors supported by the footings, the structural loading, and the requirements of the latest California Building Code. If mat slabs are utilized, alternate embedment depths can be provided.

Moisture Barrier
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‐On‐ Ground, 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‐on‐ grade 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 one 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. It is our understanding that based on the proposed structures, code allows or the use of an alternate method to calculate SD1, assuming the structure has a fundamental period that does not exceed 0.5s. The resulting values are presented in Table 7‐4.

If the structures have fundamental periods exceeding 0.5s, then a site‐specific strong motion analysis shall be performed.

7.4 Block 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 7‐5 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

15.5H2 lb/lineal ft (H=height of the wall). This force acts at approximately 0.6H above the base of the wall (inverted triangle). 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.

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 of optimum moisture (low expansion) 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 (non‐ square/rectangular) shapes.

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. 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 preliminary testing, the onsite soils are mildly corrosive to buried metal objects. Consideration should be given to protecting buried metals from corrosion. Typical measures may include using non‐corrosive 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 Site Drainage
Positive drainage away from the proposed structures should be provided and maintained. Roof, pad, and lot drainage should be collected and directed away from the structures toward approved disposal areas through drainage terraces, gutters, down drains, and other devices. Design fine grade elevations should be maintained through 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. Residents or Homeowner Associations should be made aware that they are responsible for maintenance and cleaning of Item #6. Page 1318

all drainage terraces, down drains, and other devices that have been installed to promote site and structure drainage.

7.11 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 7‐6. These sections should be verified upon the completion of grading, based on R‐Value testing.

AB‐Caltrans Class II Base
The underlying subgrade soil should be suitably moisture conditioned, processed and compacted to a minimum of 90 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 should consist of Class 2 (Caltrans) aggregate base and should be compacted to at least 95 percent of the maximum laboratory dry density as determined in accordance with ASTM Test Method: D 1557.

Preparation for compaction operations and pavement construction operations should be accomplished in accordance with the current requirements of the City of Glendora and under the observation and testing of the project geotechnical consultant.

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, backyard 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 through 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
Residents or 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.

10.0 CLOSURE

10.1 Geotechnical Review
For the purposes of this report, multiple working hypotheses were established for the project, utilizing the available data and the most probable model is used for the analysis. Future information collected during the proposed grading operations is intended to evaluate the hypothesis and as such, some of the assumptions summarized in this report may need to be changed. Some modifications of the grading recommendations may become necessary, should the conditions encountered in the field differ from the conditions hypothesized in this report.

Plans and sections of the project specifications should be reviewed by Alta to evaluate conformance with the intent of the recommendations contained in this report. If the project description or final design varies from that described in herein, Alta must be consulted regarding the applicability of the recommendations contained herein and whether any changes are required. Alta accepts no liability for any use of its recommendations if the project description or final design varies and Alta is not consulted regarding the alterations.

10.2 Limitations
This report is based on the following: 1) the project as presented on the attached plan; 2) the information obtained from Alta's laboratory testing included herein; and 3) from the information presented in the referenced reports. The findings and recommendations are based on the results of the subsurface investigation, laboratory testing, and office analysis combined with an interpolation and extrapolation of conditions between and beyond the subsurface excavation locations. However, the materials adjacent to or beneath those observed may have different characteristics than those observed, and no precise Item #6. Page 1321

representations are made as to the quality or extent of the materials not observed. The results reflect an interpretation of the direct evidence obtained.

Work performed by Alta has been conducted in a manner consistent with the level of care and skill ordinarily exercised by members of the geotechnical profession currently practicing in the same locality under similar conditions. The methods used to develop the recommendations do not comprise an exact science and are not a guarantee that the interaction between the soils and proposed structures shall perform as planned. No other representation, either expressed or implied, and no warranty or guarantee is included or intended.

The recommendations presented in this report are based on the assumption that an appropriate level of field review will be provided by a geotechnical consultant who is familiar with the design and site geologic conditions. That field review shall be sufficient to confirm that geotechnical and geologic conditions exposed during grading are consistent with the geologic representations and corresponding recommendations presented in this report.

The conclusions and recommendations included in this report are applicable to the specific design of this project as discussed in this report. They have no applicability to any other project or to any other location and any and all subsequent users accept any and all liability resulting from any use or reuse of the data, opinions, and recommendations without the prior written consent of Alta.

Alta has no responsibility for construction means, methods, techniques, sequences, procedures, safety precautions, programs in connection with the construction, acts or omissions of the CONTRACTOR or any other person performing any of the construction, or for the failure of any of them to carry out the construction in accordance with the final design drawings and specifications.

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 one representative bulk sample was evaluated in accordance with ASTM D‐1557. The results are summarized in Table C.

Expansion Index Tests
One (1) expansion index test were performed to evaluate the expansion potential of typical on‐ site soil. Testing was carried out in general conformance with ASTM Test Method D‐4829. The results are presented in Table C.

Consolidation Tests
Consolidation testing was performed on two (2) 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 consolidate under each load increment until the slope of the characteristic linear secondary compression portion of the thickness versus log of time plot was apparent.  The percent Item #6. Page 1335

consolidation for each load cycle was recorded as the ratio of the amount of vertical compression to the original 1‐inch height.  The consolidation test results are shown on Plates C‐ 1 and C‐2.

Chemical Analyses
Chemical testing was performed on one select sample by Alta. The results of these tests (sulfate content, resistivity, chloride content and pH) are presented on Table C.

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.

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.

 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 may be 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 constructed within the setback zone unless properly engineered. It is suggested that plans for Item #6. Page 1343

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.
