Alternative 6: Roundabout Entry Intersection
The Roundabout Entry Intersection Alternative (Alternative 6) is an alternative roundabout design for the intersection on Avenue 40 at the main entrance of the project site. All other characteristics of the project would remain the same with this alternative; the project would include 1,500 residential units, a Community Clubhouse, and recreation/open space areas.
The roundabout design would include accommodations for pedestrians, bicyclists, golf carts, vehicles, and emergency vehicles. Vehicles would en ter the roundabout by yielding to traffic approaching from the left; only right turns are permitted. Bicyclists and golf carts would have the option to travel within the roundabout or use the sidewalks and crosswalks surrounding the roundabout. Bicycle exit and entrance ramps are included to allow bicyclists to shift between the bicycle lane and sidewalk prior to and after departing the roundabout. Pedestrians would use the existing sidewalks and new sidewalks on Avenue 40 and around the roundabout. Crosswa lks are proposed on all four legs of the roundabout. Safety features including vehicle deflection angles, yield signs/markers, and raised reflective pavement markers would be provided at the pedestrian crossings.
Finding and Facts in Support of Finding
Impacts related to the Roundabout Entry Intersection Alternative would be similar to agriculture, air quality, biological resources, cultural resources, energy, geology and soils, greenhouse gas emission, hydrology and water quality, land use and planning, noise, fire services, law enforcement, library facilities, and dry utilities. The roundabout would have sufficient capacity to accommodate projected traffic volumes at the intersection of Avenue 40 with the primary entrance to the project and Camino San Gr egorio. N either a standard intersection nor a roundabout intersection would result in any significant traffic safety hazard impacts.
The City Council of the City of La Quinta rejects the Roundabout Entry Intersection Alternative for the following reasons:
1. Impacts related to the Roundabout Entry Intersection Alternative would be similar to agriculture, air quality, biological resources, cultural resources, energy, geology and soils, greenhouse gas emission, hydrology and water quality, land use and planning, noise, fire services, law enforcement, library facilities, and dry utilities, and no significant impacts of the project would be substantially lessened or avoided.
2. While neither a standard intersection nor a roundabout intersection would result in any significant traffic safety hazard impacts, after considering the comments of the surrounding communities and the City’s traffic engineer, the City Council finds the standard intersection to be more desirable that the roundabout.
The City Council therefore finds the Roundabout Entry Intersection Alternative is unacceptable and rejects it.

Additional Findings Regarding the Environmentally Superior Alternative
A summary comparison of impacts associated with the project Alternatives is provided in the Draft EIR in Table 6.0-14, Comparison of Alternatives to project. Of the Alternatives considered in this Draft EIR section, the No project/No Development Alternative is environmentally superior to the other Alternatives because this Alternative would avoid any impacts identified for the project or any other alternative.
Although Alternative 1 is environmentally superior, it does not meet any of the objectives of the proposed project because it would not involve any development of the site.
The CEQA Guidelines require that the EIR identify an environmentally superior alternative to the project and “if the environmentally superior alternative is the ‘no project’ alternative, the EIR shall also identify an environmentally superior alternative among the other alternatives.” CEQA Guidelines Section 15126[e][2]. In general, the environmentally superior alternative minimizes adverse impacts to the environment, while still achieving the basic project objectives.
Of the remaining alternatives, Alternative 5, the Reduced Intensity Alternative, would be the environmentally superior alternative because it would result in the greatest incremental reduction of the overall level of impacts when compared to the project. Alternative 5 would reduce, but not avoid or reduce to a level of less than significant, any of the potentially significant impacts of the project.
As the Reduced Density Alternative would develop all of the components proposed by the project, this Alternative would be consistent with the objective to establish a high-quality, master-planned age restricted community. However, Alternative 5 would not meet the objective to reflect consistency with the goals and polic ies of the City’s current General Plan for the project site, which the City Council finds to be inconsistent with the General Plan and unacceptable for that reason; furthermore, it would not comply with applicable state housing laws. Lastly, Alternative 5 is unlikely to be financially feasible as its reduced densities would generate substantially less revenue, which may be insufficient to meet the cost of the development.
Overall, the Reduced Intensity Alternative would not meet the project objectives to the same extent as the project and because the proposed project will not result in any significant impacts with mitigation, this alternative would not avoid or substantially lessen any significant impacts that would result from the proposed project.
While Alternative 5 is considered to be the environmentally superior alternative, the City Council rejects it as infeasible because it is inconsistent with the City’s General Plan and California’s current housing policies. As a result, Alternative 5 is rejected.
VII. FINDINGS REGARDING GROWTH INDUCING IMPACTS
Section 15126.2(d) of the California Environmental Quality Act (CEQA) Guidelines, as amended, requires an EIR to include a discussion of if and how a project could directly or indirectly foster
AGENDA ITEM #10.2
Resolution No. 10386 approving the Specific Plan, Resolution No. 10387 a... Page 933 of 959
economic growth, population growth, or the construction of additional housing in the surrounding environment and any resulting impacts on the environment. CEQA requires the discussion to address projects that would remove obstacles to population growth and consider any characteristics of a project which may encourage or facilitate other activities that could significantly affect the environment, either individually or cumulatively, and that growth in an area should not be considered beneficial, detrimental, or of little significance.
In general terms, a project may foster spatial, economic, or population growth in a geographic area if it:
• Removes an impediment to growth (e.g., the establishment of an essential public service or the provision of new access to an area).
• Creates economic expansion or growth (e.g., construction of additional housing, changes in revenue
base, employment expansion, etc.).
• Involves a precedent-setting action (e.g., an innovation, a change in zoning or general plan designation).
• Develops or encroaches into an isolated or adjacent undeveloped or open space area.
Findings and Facts in Support of Findings:
The City Council finds that the project would not result in the removal of an impediment to growth or involve the approval of a precedent setting actions that could result in additional growth in the area the project site is located in beyond what is already contemplated in the General Plan. In addition, the proposed project would neither cause growth (i.e., new employment) nor accelerate development in an undeveloped area that exceeds projected/planned levels for the year of project buildout as the proposed project would be consistent with the adopted employment, housing, and population policies of SCAG’s 2020- 2045 RTP/SCS and the City’s General Plan. The project would develop an existing undeveloped property with uses consistent with the City’s plans and would not involve the development of open space areas. While the project will include construction of a new IID substation that will serve the project and enhance the resilie ncy and reliability of the IID system, including help serve the growing electricity demand for existing customers in the project vicinity, the substation will not facilitate growth in excess of what is planned in the General Plan. For these reasons, the potential for the project to induce additional growth is considered low and the potential for additional environmental impacts to result from additional growth that could be induced by the project is considered less than significant.
VIII. FINDINGS REGARDING SIGNIFICANT IRREVERSIBLE
ENVIRONMENTAL CHANGES
The CEQA Guidelines state that “[u]ses of nonrenewable resources during the initial and continued phases of the project may be irreversible since a large commitment of such resources makes removal o r nonuse thereafter unlikely.” Primary impacts and, particularly, secondary impacts (such as highway improvement that provides access to a previously inaccessible area) generally commit future generations to similar uses. Also, irreversible damage can result from environmental
AGENDA ITEM #10.2
Resolution No. 10386 approving the Specific Plan, Resolution No. 10387 a... Page 934 of 959
accidents associated with a project. Irretrievable commitments of resources should be evaluated to ensure that such current consumption is justified.
Findings and Facts in Support of Findings:
The City Council finds that implementation of the project would irreversibly commit approximately 378 acres of the vacant and undeveloped site for residential and open space/recreational uses. However, no significant unavoidable adverse environmental effects would result from development. Implementation of all feasible mitigation measures, conditions of approval, project design guidelines, and local, state, and federal regulations would reduce all potential impacts to less than significant.
The irreversible environmental changes of this urba nization include incremental degradation of the regional air quality, additional noise created by traffic generated by future inhabitants of the project site, incremental demands for public services and utilities, and changes to the visual environment that will not likely be reversed. Primary impacts would result from the consumption of nonrenewable resources during construction and operation of the project. Nonrenewable resources such as sand, gravel, and steel, and renewable resources such as lumber, woul d be consumed during project construction. Energy, fossil fuels, oils, and natural gas would be irreversibly committed during construction. These same resources are used for vehicles and heating/cooling equipment during operations. The continued use of these resources associated with project operations represents a long- term obligation. The energy consumed in developing and maintaining the site for urban use may be considered a permanent investment. Construction of the project would consume limited amounts of certain types of lumber; other raw materials in steel; metals such as copper and lead; aggregate materials used in concrete and asphalt such as sand and stone; water, petrochemical construction materials such as plastic; petroleum- based construction materials; and other similar slowly renewable or nonrenewable resources. Additionally, fossil fuels for construction vehicles and equipment would be consumed.
In terms of project operations, the following slowly renewable and nonrenewable resources would be required: natural gas and electricity, petroleum -based fuels, fossil fuels, and water. The California Administrative Code regulates the amount of energy consumed by new development for heating, cooling, ventilation, and lighting purposes. Nevertheless, the consumption of such resources would represent a long- term commitment of those resources. The commitment of resources required for the construction and operation of the project would limit the availability of such resources for future generations or for other uses during the life of the project. However, continued use of such resources is consistent with the anticipated growth and planned changes on the project site and within the general vicinity.
The project would also result in an increased commitment of certain public services to the proposed land uses, including the provision of police, fire, and emergency medical services, water supply services, wastewater treatment services, dry utilities, and solid waste disposal. However, as indicated in the respective sections of the Final EIR, impacts associated with these public services would be less than significant. In addition, the project would result in a long- term, irreversible change to the nature of the project site. The vacant and undeveloped character of the site would be transformed into a residential community. However, as discussed in Section 5.3: Biological
AGENDA ITEM #10.2
Resolution No. 10386 approving the Specific Plan, Resolution No. 10387 a... Page 935 of 959
Resources, the project site does not contain habitat suitable for protected species and would not impact a Habitat Conservation Area.
Project implementation will cause the average daily trips (ADT) to increase substantially when combined with ambient growth in the vicinity. The increased number of vehicles will contribute to the degradation of air quality. However, the project air quality analysis indicates that impacts to air quality would be less than significant with mitigation. A secondary impact that results from increased traffic is an increase in ambient noise levels. Currently, the area surrounding the project is developed with re latively medium to high ambient noise levels. Once the project conducts roadway improvements and introduces project traffic on those roads, the noise levels will increase, including along roadway segments next to existing sensitive receptors. However, this increase would not significantly impact sensitive receptors and would be similar to existing development.
The project’s contribution to state, national, and global greenhouse gases (GHG) emission inventories and the resultant effect on global climate ch ange is evaluated on a cumulative basis.
Secondary impacts result from fuel consumption in the form of air pollution, which both degrades air quality in general and contributes to the formation of GHGs that cumulatively affect global warming. Human activit ies associated with industrial/manufacturing, utilities, transportation, residential, and agricultural sectors contribute to GHG emissions. While the project would generate GHG emissions, its contribution was found not to be cumulatively considerable.

MITIGATION MONITORING PROGRAM
1.0 INTRODUCTION
As the Lead Agency under the California Environmental Quality Act (CEQA; Public Resources Code Section 21000 et seq.), the City of Indio (City) prepared an Environmental Impact Report (EIR) for the Desert Retreat Specific Plan (Project) in accordance with CEQA. This Mitigation Monitoring and Reporting Program (MMRP) has been prepared to provide a program for reporting, enforcing, and monitoring the implementation of mitigation measures adopted for the Project. The Lead Agency responsibility originates in Public Resources Code § 21081.6(a) (Findings), and the State CEQA Guidelines Section 15091(d) (Findings) and 15097 (Mitigation Monitoring or Reporting).
As required by Section 15097 of the CEQA Guidelines, this MMRP has been prepared for monitoring or reporting on the measures adopted to mitigate or avoid significant environmental effects of the Project.
2.0 MONITORING AUTHORITY
The purpose of an MMRP is to ensure that measures adopted to mitigate or avoid significant impacts are implemented. A MMRP can be a working guide to facilitate not only the implementation of mitigation measures by individual project proponents, but also the monitoring, compliance/enforcement, and reporting activities of the appropriate jurisdiction.
The City may delegate duties and responsibilities for monitoring to other environmental monitors or consultants as deemed necessary, and some monitoring responsibilities may be assumed by responsible agencies, such as affected jurisdictions and cities, and state agencies. The number of construction monitors assigned to the Project will depend on the number of concurrent construction activities and their locations.
The City ’s Community Development Director (or equivalen t position or appropriate agency representative) or his/her designee(s) will ensure that personal parties delegated duties or responsibilities are qualified to monitor compliance and enforcement. It is the responsibility of the environmental monitor assign ed to each measure to ensure that appropriate agency reviews and approvals are obtained.
The City’s Community Development Director or his/her designee will also ensure that any deviation from the procedures identified under the monitoring program is approved by the City. Any deviation and its correction shall be reported immediately to the City or its designee by the environmental monitor assigned to the construction spread.

City of Indio 2 Desert Retreat Specific Plan Project MMRP Meridian Consultants May 2023
3.0 ENFORCEMENT RESPONSI BILITY
The City is responsible for enforcing the procedures adopted for monitoring through the environmental monitor assigned to each construction activity. The MMRP guides implementation of mitigation measures and specifies the type of compliance, monitoring, and reporting required with regard to those measures.
Any assigned environmental monitor shall note problems with monitoring, notify appropriate agencies or individuals about any problems, and report the problems to the City’s Community Development Director (or equivalent position for the applicable agency representative) or his/her designee. The City ’s Community Development Director (or equivalent position for the applicable agency representative) or his/her designee will also ensure that any deviation from the procedures identified under the monitoring program is approved by the City ’s Community Development Director (or equivalent position for the applicable agency representative).
4.0 MITIGATION COMPLIANC E RESPONSIBILITY
The City is responsible for successfully implementing all the mitigation measures in the MMRP and is responsible for ensuring that these requirements are met by all of its construction contractors and field personnel. Standards for successful mitigation are included in some of the adopted mitigation measures.
Additional mitigation success thresholds may be established by applicable agencies with jurisdiction through the permit process and through the review and approval of specific plans for the implementation of mitigation measures.
5.0 GENERAL MONITORING P ROCEDURES
Environmental Monitors. Many of the monitoring procedures will be conducted during the construction phase of the Project. The City is responsible for integrating the mitigation monitoring procedures into the construction process. To oversee the monitoring procedures and to ensure success, the City ’s Community Development Director may assign an environmental monitor assigned to each const ruction activity who must be on site during that portion of construction that has the potential to create a significant environmental impact or other impact for which mitigation is required, and that the monitoring program is followed.
Construction Personnel. A key feature contributing to the success of mitigation monitoring will be obtaining the full cooperation of construction personnel and supervisors. Many of the mitigation measures require action on the part of the construction supervisors or crews for successful implementation. To ensure success, the following actions, detailed in specific mitigation measures, will be taken:
• Procedures to be followed by construction contractors hired to do the work will be written into contracts between the City and an y construction contractors. Procedures to be followed by construction crews will be written into a separate document that all construction personnel will be asked to sign, denoting agreement.
• One or more pre -construction meetings will be held to inform all and train construction personnel about the requirements of the monitoring program.

Resolution No. 10386 approving the Specific Plan, Resolution No. 10387 a... Page 940 of 959 Mitigation Monitoring and Reporting Program
City of Indio 3 Desert Retreat Specific Plan Project MMRP Meridian Consultants May 2023
• A written summary of mitigation monitoring procedures will be provided to construction supervisors for all mitigation measures requiring their attention.
General Reporting Procedures. Site visits and specified monitoring procedures performed by other individuals will be reported to the City ’s Community Development Director , his/her designee(s) and/or environmental monitor assigned to the relevant construction spread. A monit oring record form will be submitted to the environmental monitor by the individual conducting the visit or procedure so that details of the visit can be recorded, and progress tracked by the environmental monitor. A checklist will be developed and maintain ed by the City ’s Community Development Director , his/her designee(s) and/or environmental monitor to track all procedures required for each mitigation measure and to ensure that the timing specified for the procedures is properly completed. The environmental monitor will note any problems that may occur and take appropriate action to rectify the problems.
Public Access to Records . The public is allowed access to records and reports used to track the monitoring program. Monitoring records and reports will be made available for public inspection by the City’s Community Development Director or his/her designee on request.
6.0 CHANGES TO MITIGATIO N MEASURES
Any substantive change in the monitoring and reporting plan made by the applicable jurisdiction shall be reported in writing to the City ’s Community Development Director (or equivalent position for the applicable agency representative) or his/her designee(s). Reference to such changes shall be made in the monthly/yearly Environmental Mitigation Monitoring and Reporting Report prepared by the appropriate jurisdiction. Modifications to the mitigation measures may be made by the appropriate jurisdiction subject to one of the following findings, documented by evidence included in the record:
(a) The mitigation measure included in the Final EIR and the MMRP is no longer required because the significant environmental impact identified in the Final EIR has been found not to exist, or to occur at a level which makes the impact less than significant as a result of changes in the Project, changes in conditions of the environment, or other factors.
OR
(b) The modified or substitute mitigation measure to be included in the MMRP provides a level of environmental protection equal to or greater than that afforded by the mitigation measure included in the Final EIR and the MMRP.
The modified or substitute mitigation measure does not have significant adverse effects on the environment in addition to or greater than that which was considered by the responsible hearing bodies in their decisions on the Final EIR and the Project.
The modified or substitute mitigation measure is feasible, and the appropriate jurisdiction, through measures included in the MMRP or other agency procedures, can ensure its implementation.

MM AQ-1: Construction Emissions.
Construction contractors shall, at a minimum, use equipment that meets the USEPA’s Final Tier 4 emissions standards for off-road diesel- powered construction equipment with 50 horsepower (hp) or greater, for all phases of construction activity, unless it can be demonstrated to the City with substantial evidence that such equipment is not available. To ensure that Final Tier 4 construction equipment or better shall be used during the proposed Project’s construction, the City shall include this requirement in applicable bid documents, purchase orders, and contracts. The City shall also require periodic r eporting and provision of written construction documents by construction contractor(s) and conduct regular inspections to the maximum extent feasible to ensure and enforce compliance.
Where Final Tier 4 equipment is not available, the Project shall use Tier 3 equipment outfitted with Best Available Control Technology devices including a CARB certified Level 3 Diesel Particulate Filter (DPF). Level 3 DPF ’s are capable of achieving at least 85 percent reduction in particulate matter emissions. Any emissions c ontrol device used by the contractor shall achieve emissions reductions that are no less than what could be achieved by Final Tier 4 emissions standards for a similarly sized engine, as defined by the CARB ’s regulations. Successful contractors must demonst rate the ability to supply the compliant construction equipment for use prior to any ground disturbing and construction activities. The Project representative will make available to the lead agency and SCAQMD a comprehensive inventory of all off -road const ruction equipment, equal to or greater than 50 horsepower, which will be used during construction. The inventory will include the horsepower rating, engine production year, and certification of the specified Tier standard. A copy of each unit’s certified tier specification, BACT documentation, and CARB or SCAQMD operating permit shall be maintained on site at the time of mobilization for each applicable piece of construction equipment.

MM BIO-2: Nesting Birds.
Regardless of the time of year, nesting bird surveys shall be performed by a qualified avian biologist no more than 3 days prior to vegetation removal or ground-disturbing activities associated with each phase of the Project. Pre- construction surveys shall focus on both direct and indirect evidence of nesting, including nest locations and nesting behavior. The qualified avian biologist will make every effort to avoid potential nest predation as a result of survey and monitoring efforts.
If active nests are found during the pre -construction nesting bird surveys, a qualified biologist shall establish an appropriate nest buffer to be marked on the ground. Nest buffers are species specific and shall be at least 300 feet for passerines and 500 feet for raptors. A smaller or larger buffer may be determined by a qualified biologist familiar with the nesting phenology of the nesting s pecies and based on nest and buffer monitoring results. Established buffers shall remain on-site until a qualified biologist determines if the young have fledged or the nest is no longer active. Active nests and adequacy of the established buffer distance shall be monitored by the qualified biologist until the qualified biologist has determined the young have fledged or the Project has been completed. The qualified biologist has the authority to stop work if nesting pairs exhibit signs of disturbance.

MM CUL-1: SRI 15 Data Recovery.
Prior to the implementation of mass grading, clearing, or grubbing, given the subsurface component of SRI 15 and the potential for human remains, consultation with Tribal entities concerning the Site should occur s o that appropriate measures are taken to adequately and respectfully mitigate any adverse effects that the development may have on the Site.
Because implementation of the Project as proposed would significantly impact the site, including the planned development of the SRI-15 area, avoidance of the SRI 15 site is not feasible. Therefore, an archaeological data recovery plan shall be drafted and implemented for the site in a manner consistent with established professional archaeological standards and in cons ultation with the Agua Caliente, Morongo, and Cabazon Tribes. Data recovery efforts will be led by a qualified principal archaeologist meeting the Secretary of the Interior’s Professional Qualifications Standards for Archeology and monitored by tribal representatives. This archaeological data recovery plan will include the professional qualifications required of key staff and detail excavation methods as well as methods used to analyze recovered artifacts and samples. Implementation of the data recovery plan will reduce to an insignificant level potential Project effects on SRI 15.
MM CUL-2: Archaeological Monitoring.
Prior to the start of Project ground disturbance, including demolition and vegetation removal, a qualified principal archaeologist meeting the Secretary of the Interior’s Professional Qualifications Standards for Archeology, shall be retained to prepare and implement a written Cultural Resource Monitoring and Treatment Plan (CRMTP) that is consistent with established professional archaeological standards and subject to the approval of the City.

MM GEO-1: Site Preparation and Remedial Grading.
Prior to grading, the proposed structural improvement areas (i.e., all structural fill areas, pavement areas, buildings, etc.) of the site should be cleared of surface and subsurface obstructions, heavy vegetation and boulders. Roots and debris should be d isposed of off site. Septic Tanks or seepage pits, if encountered, should be abandoned in accordance with the County of Riverside Department of Health Services guidelines.
The near surface soils/alluvium (including artificial fill/stockpiles) are potentially compressible in their present state and may settle under the surcharge of fills or foundation loading. As such, these materials should be removed (over -excavated) and re -compacted in all settlement-sensitive areas. We recommend that the upper 5 feet of alluvium or 3 feet below bottom of footings, whichever deeper, should be removed/over -excavated and recompacted prior to foundation construction or placement of any additional fill. The removal limit should be established by a 1:1 (horizontal: vertical) pr ojection from the edge of fill soils supporting settlement -sensitive structures downward and outward to competent material identified by the geotechnical consultant. Removal will also include benching into competent material as the fills rise. Areas adjace nt to existing structures or property limits may require special considerations and monitoring. Steeper temporary slopes in these areas may be considered.
MM GEO-2: Structural Fills.
The on-site soils are generally suitable for re -use as compacted fill , provided they are free of debris and organic matter. Areas to receive structural fill and/or other surface improvements should be scarified to a minimum depth of 8 inches, conditioned to at least optimum City of Indio

moisture content, and recompacted. Fill soils should be placed at a minimum of 90 percent relative compaction ( based on ASTM D1557) and near or above optimum moisture content. Placement and compaction of fill should be performed in accordance with local grading ordinances under the observation and testing of the geotechnical consultant. The optimum lift thickness to produce a uniformly compacted fill will depend on the type and size of compaction equipment used. In general, fill should be placed in uniform lifts not exceeding 8 inches in thickness.
Fill slope keyways will be necessary at the toe of all fill slopes and cut slope replacement fills. Keyway schematics, including dimensions and subdrain recommendations, are provided in Appendix D. All keyways should be excavated into dense bedrock or dens e alluvium as determined by the geotechnical engineer. The cut portions of all slope and keyway excavations should be geologically mapped and approved by a geologist prior to fill placement.
Fills placed on slopes steeper than 5:1 (horizontal: vertical) should be benched into dense soils (see Appendix D for benching detail).
Benching should be of sufficient depth to remove all loose material. A minimum bench height of 2 feet into approved material should be maintained at all times.
MM GEO-3: Shrinkage and Subsidence.
The volume change of excavated on-site materials upon compaction is expected to vary with materials, volume of roots and deleterious materials, density, in situ moisture content, location, and compaction effort. The in place and compacted densities of soil materials vary and accurate overall determination of shrinkage and bulking cannot be made. Therefore, we recommend site grading include, if possible, a balance area or ability to adjust import quantities to accommodate some variation. Based on our experience with similar materials, we anticipate 10 to 15 percent shrinkage in the upper 5 feet of dune sand/alluvium.
Subsidence due solely to scarification, moisture conditioning , and recompaction of the exposed bottom of over excavation is expected

to be on the order of 0.15 foot. This should be added to the above shrinkage value for the recompacted fill zone, to calculate overall subsidence.
MM GEO-4: Import Soils.
Import soils and/or borrow sites, if needed, should be evaluated by the geotechnical consultant prior to import. Import soils should be uncontaminated, granular in nature, free of organic material (loss on ignition less -than 2 percent), have a very low expansion potential (with an Expansion Index less than 21) and have a low corrosion impact to the proposed improvements.
MM GEO-5: Utility Trenches.
Utility trenches should be backfilled with compacted fill in accordance with Sections 306 -1.2 and 306 -1.3 of the Standard Specifications for Public Works Construction, (“Greenbook”), 2018 Edition (or most recent). Fill material above the pipe zone should be placed in lifts not exceeding 8 inches in uncompacted thickness and should be compacted to at least 90 percent relative compaction (ASTM D 1557) by mechanical means only. Site s oils may generally be suitable as trench backfill provided these soils are screened of rocks over 1½ inches in diameter and organic matter. If imported sand is used as backfill, the upper 3 feet in building and pavement areas should be compacted to 95 perc ent. The upper 6 inches of backfill in all pavement areas should be compacted to at least 95 percent relative compaction.
Where granular backfill is used in utility trenches adjacent moisture sensitive subgrades and foundation soils, we recommend that a cu t- off “plug” of impermeable material be placed in these trenches at the perimeter of buildings, and at pavement edges adjacent to irrigated landscaped areas. A “plug” can consist of a 5 -foot-long section of clayey soils with more than 35-percent passing the No. 200 sieve, or a Controlled Low Strength Material (CLSM) consisting of one sack of Portland-cement plus one sack of bentonite per cubic -yard of sand.
CLSM should generally conform to Section 201 -6 of the Standard Specifications for Public Works Constr uction, (“Greenbook”), 2018

Edition. This is intended to reduce the likelihood of water permeating trenches from landscaped areas, then seeping along permeable trench backfill into the building and pavement subgrades, resulting in wetting of moisture sensi tive subgrade earth materials under buildings and pavements.
Excavation of utility trenches should be performed in accordance with the Project plans, specifications, and the California Construction Safety Orders (current Edition). The contractor should be responsible for providing a "competent person" as defined in Article 6 of the California Construction Safety Orders. Contractors should be advised that sandy soils (such as fills generated from the on-site alluvium) could make excavations particularly unsa fe if all safety precautions are not properly implemented. In addition, excavations at or near the toe of slopes and/or parallel to slopes may be highly unstable due to the increased driving force and load on the trench wall. Spoil piles from the excavatio n(s) and construction equipment should be kept away from the sides of the trenches. Leighton does not consult in the area of safety engineering.
MM GEO-6: Drainage.
All drainage should be directed away from structures, slopes, and pavements by means of ap proved permanent/ temporary drainage devices. Adequate storm drainage of any proposed pad should be provided to avoid wetting of foundation soils. Irrigation adjacent to buildings should be avoided when possible. As an option, sealed - bottom planter boxes an d/or drought resistant vegetation should be used within 5-feet of buildings.
MM GEO-7: Slope Design and Construction.
Based on our understanding and planning purposes, all fill and cut slopes will be designed and constructed at 2:1 (horizontal: vertical) with benches at maximum 30 -foot intervals. These slopes are considered grossly stable for static and pseudo static conditions. For planning purposes, cut slopes exceeding 5 feet in height should be constructed as replacement fill slopes due to the highly erosive nature

of site soils. Future grading plans should be subject to further review and evaluation.
The outer portion of fill slopes should be either overbuilt by 2 feet (minimum) and trimmed back to the finished slope configuration or compacted in vertical increments of 5 feet (maximum) by a weighted sheepsfoot roller as the fill is placed. The slope face should then be track-walked by dozers of appropriate weight to achieve the final slope configuration and compaction to the slope face.
Slope faces are inherently subject to erosion, particularly if exposed to wind, rainfall, and irrigation. Landscaping and slope maintenance should be conducted as soon as possible in order to increase long-term surficial stability. Berms should be provided at the top of f ill slopes.
Drainage should be directed such that surface runoff on the slope face is minimized.
MM GEO-10: Vapor Retarder.
It has been a standard of care to install a moisture retarder underneath all slabs where moisture condensation is undesirable. Mois ture vapor retarders may retard but not totally eliminate moisture vapor movement from the underlying soils up through the slabs. Moisture vapor transmission may be additionally reduced by use of concrete additives. A qualified person/firm shall be engaged and consulted with to evaluate the general and specific moisture vapor transmission paths and any impact on the proposed construction and make to avoid moisture vapor transmission on various components of the structure as deemed appropriate. The slab subgrade soils should be well wetted prior to placing concrete.
MM GEO-12: Geochemical Characteristics.
Additional corrosion testing should be performed on representative finish grade soils at the completion of rough grading. Concrete foundations in contact with site soils should be designed in accordance with 2019 CBC. A qualified corrosion engineer should be consulted to

review the results of laboratory tests and coordinate additional testing if corrosion sensitive materials are to be used.
MM GEO-13: Preliminary Pavement Design.
The subgrade soils in the upper 6 inches should be properly compacted to at least 95 percent relative compaction (ASTM D1557) and should be moisture conditioned to near optimum and kept in this condition until the pavement section is constructed. Proof -rolling subgrade to identify localized areas of yielding subgrade (if any) should be performed prior to placement of aggregate base and under the observation of the geotechnical consultant.
Minimum relative compaction requirements for aggregate base should be 95 percent of the maximum laboratory den sity as determined by ASTM D1557. Base rock should conform to the “Standard Specifications for Public Works Construction” (green book) current edition or Caltrans Class 2 aggregate base having a minimum R -value of 78. Asphaltic concrete should be placed on compacted aggregate base and compacted to a minimum 95 percent relative compaction.
iii. Seismic-related ground
failure, including
liquefaction?
MM GEO-8: Bearing and Lateral Pressures.
Based on our analysis, the proposed residential/ and
retail/commercial structures may be founded on conventional foundation systems based on the design parameters provided below.
The proposed foundations and slabs should be designed in accordance with the structural consultants ’ design, the minimum geotechnical recommendations presented herein, and the 2019 CBC. In utilizing the minimum geotechnical foundation recommendations, the structural consultant should design the foundation system to acceptable deflection criteria as determined by the architect. Foundation footings may be designed with the following geotechnical design parameters:
• Bearing Capacity: A net allowable bearing capacity of 2,000 pounds per square foot (psf), or a modulus of subgrade re action of 150 pounds per cubic inch (pci) may be used for design of footings founded entirely into compacted fill. The footings should Refer above. Refer above.

extend a minimum of 12 inches below lowest adjacent grade. A minimum base width of 18 inches for continuous footings and a minimum bearing area of 3 square feet (1.75 ft by 1.75 ft) for pad foundations should be used. Additionally, an increase of one-third may be applied when considering short -term live loads (e.g., seismic and wind).
• Passive Pressures: The passive earth pressure may be computed as an equivalent fluid having a density of 300 psf per foot of depth, to a maximum earth pressure of 3,000 pounds per square foot. A coefficient of friction between soil and concrete of 0.35 may be used with dead load forces. When combining passive pressure and frictional resistance, the passive pressure component should be reduced by one-third.
MM GEO-9: Settlement.
The Project civil engineer, structural engineer, and architect should consider the potential effects of both static set tlement and dynamic settlement presented below.
• Static Settlement: Most of the static settlement of on-site soils is expected to be immediate or within 30 days following fill placement. A differential static settlement of 0.5 inch over a 30- foot span may b e considered for design purposes. Additional settlement will also occur in the future if sites grades are raised or due to specific or large footing/foundation loads.
• Dynamic Settlement : Based on our analysis, we estimate that total dynamic settlement is expected to be less than 5.0 inch. Due to relatively uniform alluvium, this settlement is expected to be global and differential settlement is expected to be minimal or less than 0.25 inches over a 40foot horizontal span.

low expansive soils that are free draining. In the design of walls restrained from movement at the top (non-yielding) such as basement or elevator pit/utility vaults, the at-rest equivalent fluid weight value should be used. Total depth of retained earth for design of cantilever walls should be measured as the vertical distance below the ground surface measured at the wall face for stem design, or measured at the heel of the footing for overturning and sliding calculations. Should a sloping backfill other than a 2:1 (horizontal:vertical) be constructed above the wall (or a backfill is loaded by an adjacent surcharge load), the equivalent fluid weight values provided above should be re - evaluated on an individual case basis by us. Non-standard wall designs should also be reviewed by us prior to construction to check that the proper soil parameters have been incorporated into the wall design.
