INTRODUCTION 1.1 General KANE GeoTech, Inc. (KANE GeoTech) was retained by Newbridge Homes, LLC (Newbridge Homes) to investigate potential rockfall hazards that might affect residential development on the undeveloped lot south of the intersection of Live Oak Avenue and Village Drive in Fontana, San Bernardino California. This report was prepared by KANE GeoTech to provide information on the assessment of potential rockfall hazards at the Project site. The Project location is shown in Figure 1 with an aerial overview of the site in Figure 2. 1.2 Purpose The purpose of this report is to present the results of rockfall analyses performed to assess the potential rockfall hazards at the Project site. This report also provides probable rockfall source areas and trajectories and general options for mitigation. 2. SCOPE OF WORK 2.1 Scope The scope of services provided by KANE GeoTech included the following: 1.Literature Review. KANE GeoTech reviewed available geotechnical information, reports, and maps provided by Newbridge Homes and others which were pertinent to the Project. This included, but was not limited to, soil (geotechnical) reports, surveys, geological and engineering studies. 2.Rockfall Analyses.

The purpose of modeling the rockfall was to determine the required height and energy of any proposed mitigation measures. 3.Report of Findings. KANE GeoTech prepared this Report of Findings containing the results of our analyses and an engineering assessment of the rockfall hazards at the Project site. The Report provides recommendations to mitigate, treat, and/or remove any potential hazards. These recommendations include all areas within the project limits. This Report also includes a list of qualified rockfall mitigation system installers. 3.SITE DESCRIPTION 3.1 Overview The project site is located south of Interstate 10, Fontana, San Bernardino County, California at approximately 34°02'23.6"N 117°28'49.7"W. South of the intersection of Live Oak Avenue and Village Drive. The rockfall area is roughly 2,000-ft long with terrain rising about 400-ft above the site to the east. Petra Geosciences, Inc. (Petra) (2021) developed a geotechnical due-diligence review for the subject tract. Based on their assessment, Petra identified the areas most susceptible to rockfall. 3.2 Geology The site lies in the Peninsular Ranges Geomorphic Province of California. Local geology includes topsoil and Quaternary alluvium consisting coarse-grained silty sand and gravel (Petra, 2021). The ridges of the project site are composed of Cretaceous granitic rocks, primarily consist of tonalite (Morton, 1973). Although landslides are unlikely, tonalite boulders present a rockfall hazard. Our field visit and review of aerial images suggest rock blocks as large as 10-ft in diameter have to the potential to topple and roll down the mountain. The area is seismically active and ground shaking due to seismic activity can easily cause rockfall from the outcrops above the project area. The larger outcrops are predominately near the proposed construction limits, whereas, the 2-ft to 6-ft boulders are on the highest elevation of the ridge. KANE GeoTech, Inc. DRAFT Live Oak Project Rockfall Investigation Fontana, California Page 3 Figure 3. Large blocks of loose rockfall at base of slope. Figure 4. Fractured and broken bedrock and boulders. Figure 5. Old quarry face revealing steeply overhanging large blocks with tension cracks. 3.3 Site Characteristics Dudek (2019) produced a Phase 1 environmental report in which it described the history of the site.. Originally the site was a granite stone and aggregate quarry where quarry operations were begun as early as pre- 1900. By the 1980s, quarrying was abandoned. The science of blasting was not developed during most of the years of quarrying and the results are visible today, Figure 4. The random and large unstable blocks of rock remaining fro uncontrolled blasting are responsible for current rockfall issues. KANE GeoTech personnel visited the site on June 11, 2012. The site was vacant and unused. It was heavily vegetated with low grasses and chaparral. Large boulders were scattered throughout the site and no grading had been done. We traversed the site and noted typical boulder sizes as well as locations for rockfall modeling profiles. The most notable feature of the quarry face was a large overhanging knob, Figure 5. This block exhibits a significant tension crack on the uphill side. KANE GeoTech, Inc. DRAFT Live Oak Project Rockfall Investigation Fontana, California Page 4 Figure 6. Topographic map showing rockfall profile paths analyzed 4.ROCKFALL ANALYSES 4.1 Rockfall Analyses The aerial imagery was used to develop rockfall source sites and likely rockfall trajectories. Fourteen rockfall trajectories were selected for analyses, Figure 3 and Appendix A. The sites included a rockfall source area as well as rockfall chutes and associated run-out areas. Two thousand to 3,000 rockfall simulations were conducted for each potential rockfall chute. To simulate site conditions as closely as possible, large, 10-ft diameter octagons to smaller 6-ft, 4-ft, 2-ft and 1-ft diameter octagonally-shaped boulders were modeled. The large boulders generally provide the maximum energy required to be mitigated while the small boulders tend to bounce higher and give better results as to required barrier heights. Collectors, analyses points where predicted bounce heights and energies are calculated, were located on the upslope side of the proposed trail. At least (3) collectors were used for each profile based on the project limits acquired from the Client. 4.2 Rocscience RocFall 2021 Rockfall analyses were performed using Rocscience RocFall 2021 (RocFall) software program. RocFall is a 2-dimensional rockfall simulation program that predicts statistical rockfall behavior on slopes to assist in the design of rockfall mitigation. RocFall has become the standard-of- practice rockfall modeling software in the geohazard industry. By modeling a slope using RocFall, it is possible to make reasoned judgments on the need for, or the design of, a rockfall barrier or KANE GeoTech, Inc. DRAFT Live Oak Project Rockfall Investigation Fontana, California Page 5 earthen berm. It is routinely used as a design tool by the government and private practice. RocFall uses a statistical computer algorithm based on actual rockfall tests to predict the rockfall kinetic energy, velocity, and bounce height distribution along the entire slope profile. The program also predicts the rockfall traveling and stop distances along the slope profile surface. Analysis points, called collectors, are placed at locations along the slope profile surface to determine the probable rockfall behavior statistical data at that point. This information is used to assist in determining the capacity, size, and location of the rockfall mitigation. The RocFall program contains two types of analyses methods that can be used for rockfall modeling. The Rigid Body model considers the impulse reaction of the rock during the instantaneous contact period with the slope to determine the critical events of the rock (slip, sticking, reversal) behavior during restitution. The normal coefficient of restitution is used during the two phases of the contact period to calculate the terminal impulse. With the terminal impulse, the outgoing velocities at the contact point can be calculated. The Lump Mass Model uses a particle analysis with three sections: the particle algorithm, the projectile algorithm, and the sliding algorithm. The particle algorithm ensures that the simulation parameters are valid, sets up the initial conditions, and starts the projectile algorithm. The Rigid Body Models were used for the analyses for this Project. The RocFall program includes two types of probability sampling methods used for statistical data distributions. The Monte Carlo Method uses random numbers to sample from the input data probability distributions. The Monte Carlo Method is commonly applied to a variety of sampling involving random behavior in geotechnical engineering. The Latin Hypercube Method provides similar results as the Monte Carlo Method, but with fewer samples. The method is based upon "stratified" sampling with random selection within each stratum. This results in a smoother sampling of the probability distributions. RocFall requires a 2-dimensional slope profile and the geotechnical material parameters such as rock unit weight, size, and slope roughness. In addition, coefficients of restitution are also determined to depict the behavior of rocks rebounding from the slope. Numerical representations of these properties are termed the normal coefficient of restitution (Rn) and the tangential coefficient of frictional resistance (Rt), where the normal direction is perpendicular to the slope surface, and the tangential direction is parallel to the slope surface. In determining velocity components for a rock following impact, separate normal and tangential coefficients are necessary due to the different mechanisms involved in resisting motion normal and tangent to the slope. When a rock bounces on a slope, kinetic energy is lost due to inelastic components of the collision and friction. While the primary mechanism in resisting motion parallel to the slope is sliding or rolling friction, the elasticity of the slope determines the motion normal to the slope. Rn is a measure of the degree of elasticity in a collision normal to the slope, and Rt is a measure of frictional resistance to movement parallel to the slope. The friction angle used in the analyses is calculated when using the Lump Mass Model while using the selected Rt values. KANE GeoTech, Inc. DRAFT Live Oak Project Rockfall Investigation Fontana, California Page 6 5. RESULTS 5.1 Results Table 1 is a summary of the rockfall analyses that are presented in Appendix B. Bounce heights ranged from 2-ft to 15-ft and energies varied between less than 18-kJ for the 1-ft boulders to approximately 4400-kJ for the 10-ft boulders. Table 2 presents the probability of rockfall for all boulder sizes. Majority of the simulated boulder sizes had a relatively high probability of reaching the Collector (Analyses Points) alongside the trail. Sixty-six percent of the 10-ft boulders and 61% of boulders less than 10-ft reached the Collectors (Analyses Points). 6. CONCLUSIONS AND RECOMMENDATIONS 6.1 Conclusions Based on the modeled probabilities, it is our conclusion that rockfall is a hazard that has a high potential to impact the proposed residential area. We also conclude that the rockfall hazards can be mitigated with conventionally available methodologies and materials. 6.2 Recommendations In general, rockfall mitigation can be provided with the strategies given in Table 3. Prior to the construction of any barriers a detailed rockfall study should be performed to determine the exact type, parameters, and locations of the barriers. For this project we recommend the installation of approximately 2,100 linear feet of flexible rockfall barriers along the base of the slope. The energy rating of the barriers will vary between 100-kJ and 5,000-KJ. It should be noted that the barriers will deflect as much as 20-ft when impacted by a boulder at the maximum design energy. The barriers should be located so that they are adjacent to an open space or road so that def lection will not affect any structures. We estimate the total cost of protection to be $1.74M. It is strongly emphasized that this is only an estimate based on past experience. The costs can vary significantly based on the price of steel, the availability of contractors, and other market forces. Our estimate is preliminary and conservative. Once the project goes to design, more accurate costs can be determined. At that time, we urge that at least three contractors be contacted to determine current market pricing. A list of specialized installation contractors is given in Appendix C. It is also noted that other options to decrease costs are available. such as rock removal by blasting or scaling with bars and/or air bags. Such methods can result in dramatic decreases in rockfall protection structural requirements and costs. In addition, compacted fill or mechanically stabilized earth (MSE) berms, depending on available space can be constructed to further reduce costs. KANE GeoTech, Inc.

Causes range from human construction to environmental (e.g., weather, wildfire, groundwater fluctuations) effects. Because the multiplicity of factors affecting it, it is not, and cannot be, an exact science. Therefore, the safety of individuals and property cannot be guaranteed. However, when sound engineering principles are applied to a predictable range of geodynamics, the risk of injury and property loss can be substantially reduced by the use of properly designed mitigation in identified risk areas. The analyses, conclusions and recommendations contained in this report are based on the site conditions observed by us and derived from the information provided to us. If there is a substantial lapse of time between the submission of our report and the start of any work at the site, or if conditions have changed due to natural causes, or construction operations at or adjacent to the site, we urge that our report be reviewed to determine the applicability of the conclusions and recommendations considering the changed conditions and time lapse. This report is applicable only for the project and sites studied. This report should not be used after three years.
