1. Remove only those plants which will be planted the same day. Place such plants in the proposed locations for review and accepted by the City prior to actual planting. Notify the Inspector a minimum of 48 hours prior to day of planting.

2. Dig planting pits as shown on the Plans and as shown in the Parks Construction Standards. Scarify the sides and bottom of pit to prevent glazing. Fill pit completely with water and allow the water to completely drain from the pit prior to actual planting.

3. Relocate any plantings taller than 6” in height that fall in front of any irrigation head in order to ensure proper coverage of the irrigation system.

4. For pits that retain water, completely penetrate the hardpan layer at the bottom of the pit and backfill with topsoil. Fill pit with water to test and ensure proper drainage.

5. Prior to tree planting a central leader needs to be established by structural pruning, as necessary. Codominant leaders need to be removed or suppressed by structural pruning. Refer to the CALFIRE "Tree Training", "Tree Planting", and "Tree Quality" cue cards and "Tree and Plant Root Management Standard and Quality Expectations" contained in Section 5 of these Standards.

6. Plants shall be removed from their containers only at the time of placement within the plant pit. Perform root pruning on all four sides of the root ball by shaving and cutting away the root ball periphery to reduce the amount of circling roots. Starting from the top and then cutting/slicing down to the bottom of the root ball. On a 15 gal container at least 1-1.5 inches of the root ball periphery needs to be removed by slicing or shaving. On a 24” and 36”box tree at least 2 inches of the root ball periphery needs to be removed by slicing or shaving. A sharp hand pruning saw needs to be used for the slicing or shaving of the root ball. Refer to the CALFIRE "Root Management" cue card contained in Section 5 of these Standards. This process will remove many girdling and circling roots deflected by the container wall and allows for root penetration within the planting basin. Spread all roots to the side to allow proper root development. Add native backfill and amendments as shown in the Parks Construction Standards and as recommended by the soils testing laboratory.

7. Plant tree at least three inches (2”) above grade on mount to prevent bowl effect. The tree’s beginning root flare must be located at top of grade with installed sod.

8. Carefully place plant into the plant pit without damaging the root ball. Water the backfill until saturated. For trees, water in by hand after planting using at least ten (10) gallons of water, minimum.

Assembly Bill No. 626
CHAPTER 810
An act to add and repeal Section 9204 of the Public Contract Code, relating to public contracts.
[Approved by Governor September 29, 2016. Filed with Secretary of State September 29, 2016.]
LEGISLATIVE COUNSEL’S DIGEST
AB 626, Chiu. Public contracts: claim resolution.

Existing law prescribes various requirements regarding the formation, content, and enforcement of state and local public contracts. Existing law applicable to state public contracts generally requires that the resolution of claims related to those contracts be subject to arbitration.

Existing law applicable to local agency contracts prescribes a process for the resolution of claims related to those contracts of $375,000 or less.

This bill would establish, for contracts entered into on or after January 1, 2017, a claim resolution process applicable to any claim by a contractor in connection with a public works project. The bill would define a claim as a separate demand by the contractor for one or more of the following: a time extension for relief from damages or penalties for delay, payment of money or damages arising from work done pursuant to the contract for a public work, or payment of an amount disputed by the public entity, as specified.

This bill would require a public entity, defined to exclude certain state entities, upon receipt of a claim sent by registered or certified mail, to review it and, within 45 days, provide a written statement identifying the disputed and undisputed portions of the claim. The bill would authorize the 45-day period to be extended by mutual agreement. The bill would require any payment due on an undisputed portion of the claim to be processed within 60 days, as specified. The bill would require that the claim be deemed rejected in its entirety if the public entity fails to issue the written statement.

This bill would authorize, if the claimant disputes the public entity’s written response or if the public entity fails to respond to a claim within the time prescribed, the claimant to demand to meet and confer for settlement of the issues in dispute. The bill would require any disputed portion of the claim that remains in dispute after the meet and confer conference to be subject to nonbinding mediation, as specified. The bill would provide that unpaid claim amounts accrue interest at 7% per annum. The bill would prescribe a procedure by which a subcontractor or lower tier contractor may make a claim through the contractor.

This bill would require the text of these provisions, or a summary, to be set forth in the plans or specifications for any public work which may give rise to a claim. The bill would specify that a waiver of these rights is void and contrary to public policy, except as specified. The bill would also specify that it does not impose liability on a public entity that makes loans or grants available through a competitive application process, for the failure of an awardee to meet its contractual obligations.

FOR COUNCIL APPROVAL ONLY

AB 626 - 2
[B:\City Attorney\agreement\form agreements\Project Manuals\buildings & grounds.docx; 1/4/2024] By increasing the duties of local agencies and officials, this bill would impose a statemandated local program.

This bill would, on January 1, 2020, repeal the provision establishing the claim resolution process.

This bill would specify that these provisions constitute a matter of statewide concern.

The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.

This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to these statutory provisions.

The people of the State of California do enact as follows:

GEOTECHNICAL INVESTIGATION

1.0 PURPOSE AND SCOPE
This report presents the results of our geotechnical investigation for the proposed CO-61 Park project located at 6200 Campus Parkway in Roseville, California. The approximate site location is depicted on the Vicinity Map, Figure 1.

The purpose of our investigation was to evaluate subsurface soil and geologic conditions at the site and provide conclusions and recommendations relative to the geotechnical aspects of designing and constructing the project as presently proposed.

To prepare this report, we performed the following scope of services:
• Performed a limited geologic literature review to aid in evaluating the geologic conditions present at the site. A list of referenced material is included in Section 9.0 of this report. • Performed a site reconnaissance to review project limits, determine exploration equipment access, and mark out exploratory excavation locations.
• Notified subscribing utility companies via Underground Service Alert (USA) a minimum of two business days (as required by law) prior to performing test pits at the site. • Excavated four (4) test pits (TP1 through TP4) at the site with a rubber-tire backhoe equipped with an 18-inch-wide bucket to depths of approximately 10½ and 11½ feet, each. • Obtained representative disturbed samples from the test pits. Additionally, we used a hand-driven core sampler with a 10-pound slide hammer to obtain relatively undisturbed soil samples from Test Pit TP4.
• Logged the test pits in accordance with the Unified Soil Classification System (USCS). • Upon completion, backfilled the test pits with the excavated soil. • Performed laboratory tests to evaluate pertinent geotechnical parameters. • Prepared this report to summarize our findings, conclusions, and recommendations with respect to design and construction of the project.

Approximate locations of the test pits are shown on the Site Plan, Figure 2 and Proposed Development Plan, Figure 3. Details of our field exploration program including exploratory logs are presented in Appendix A.

Details of our laboratory testing program and test results are summarized in Appendix B. Landscape soil suitability test results performed by Sunland Analytical Laboratory are presented in Appendix C.

2.0 SITE AND PROJECT DESCRIPTION
The irregular-shaped site encompasses a total area of approximately 5.75 acres. The site consists of one parcel identified as Placer County Assessor Parcel Number 481-270-079-000. The site is bounded by Ashbrook Street on the north, Knightsbridge Lane on the east, and undeveloped land on the south and west. Review of historical aerial photographs indicates that the site has been undeveloped since at least 1985. In the aerial photographs, a drainage swale is visible meandering across the site to at least April of 2023. Aerial photographs suggest that the drainage swale drains from near the northeast corner of the site towards the southwest corner and into an adjacent pond. Review of an aerial photograph taken in November of 2023 indicates that the drainage swale is no longer present which may suggest that the swale was backfilled. The site configuration and approximate former drainage swale boundaries are shown on the Site Plan, Figure 2.

The project consists of constructing a new park at the site which will include a half basketball court, a picnic area with a shade structure, a play structure with a shade canopy, landscaping, turf grass areas, underground utilities, a bike trail, and flatwork throughout the park. The new play structure and shade canopy/structures will likely be supported on spread footings or cast-in-drilled-hole (CIDH) concrete piers. New pavements will likely consist of hot-mix-asphalt (HMA) and/or rigid Portland cement concrete (PCC). Based on the master grading plans (Morton & Pitalo, Inc., 2023), the site will include maximum excavations and fills on the order of one to three feet. The proposed site configuration is shown on the Proposed Development Plan, Figure 3.

3.0 SOIL AND GEOLOGIC CONDITIONS
We identified geologic and soil conditions by observing and sampling test pits and reviewing the referenced geotechnical and geologic literature (Section 9.0). Soil descriptions below include the USCS symbol where applicable. Site geology is mapped as Alluvium, Turlock Lake Formation (map symbol Qtl) based on the Preliminary Geologic Map of the Sacramento 30’x60’ Quadrangle, California, (California Geological Survey, 2011).

3.1 Fill
We encountered undocumented fill in Test Pit TP4 from the ground surface to a depth of approximately 3 feet. The fill generally consists of medium dense clayey sand (SC). Based on in-place dry density test results of representative samples of the fill, the relative compaction is greater than 90%. Therefore, over-excavation and re-compaction of the fill is not necessary. Recommendations for scarification, moisture-conditioning, and re-compaction of the top 12 inches of soil are provided in this report.

3.2 Alluvium (Turlock Lake Formation)
Below 3 feet in Test Pit TP4 and below the ground surface in Test Pits TP1 through TP3, we encountered alluvium to the maximum explored depth of approximately 11½ feet. The alluvium generally consists of interbedded layers of very stiff to hard lean clay with sand (CL) and sandy lean clay (CL), and medium to very dense clayey sand (SC) and poorly graded sand (SP).

Soil conditions described in the previous paragraph are generalized. The boring logs included in Appendix A detail soil type, color, moisture, consistency, and USCS classification of the soils encountered at specific locations and elevations.

3.3 Landscape Soil Suitability
We submitted a near-surface bulk soil sample (TP3-Bulk) to Sunland Analytical of Rancho Cordova, California to be tested for landscape soil suitability analyses. The sample was placed in re-sealable plastic bag, labeled, and transported to Sunland Analytical Laboratory in Rancho Cordova, California.

The laboratory analytical report, prepared by Sunland Analytical, is attached as Appendix C.

4.0 GROUNDWATER
We did not encounter groundwater in our test pits excavated to depths of approximately 10½ to 11½ feet on September 9, 2025.

We reviewed available depth-to-groundwater data on the California Department of Water Resources (DWR) Sustainable Groundwater Management Act (SGMA) Data Viewer (https://sgma.water.ca.gov/webgis/?appid=SGMADataViewer#gwlevels). The SGMA Data Viewer website indicates that depth to groundwater at the site ranges from approximately 90 to 100 feet (Spring 2024).

It should be noted that fluctuations in the level of groundwater may occur due to variations in rainfall, temperature, and other factors. Depth to groundwater can also vary significantly due to localized pumping, irrigation practices, and seasonal fluctuations. Therefore, it is possible that groundwater may be higher or lower than the levels observed during our investigation.

5.0 SEISMICITY AND GEOLOGIC HAZARDS

5.1 Regional Active Faults
The site is not located within an Alquist-Priolo Earthquake Fault Zone as established by the State Geologist around known active faults. Local field reconnaissance did not reveal overt indications of an active fault trace at the site. Review of available literature indicates there are no active fault traces within 1,000 feet of the project location. The USGS Quaternary Fault and Fold Database maps the nearest active (“Historical” and “Latest Quaternary”) fault as the Foothills Fault System located approximately 14 miles to the northeast of the project location. Therefore, we consider the potential for ground rupture due to onsite active faulting to be low.

5.2 Historical Earthquakes and Ground Shaking
We used the United States Geological Survey (USGS) Unified Hazard Tool (https://earthquake.usgs.gov/hazards/interactive/) to determine the deaggregated seismic source parameters including controlling magnitude and fault distance. The USGS estimated modal magnitude is 6.5 and the estimated Peak Ground Acceleration (PGA) for the Maximum Considered Earthquake (MCE) with a 2,475-year return period is 0.25g.

While listing PGA is useful for comparison of potential effects of fault activity in a region, other considerations are important in seismic design, including frequency and duration of motion and soil conditions underlying the site.

5.3 Liquefaction
Liquefaction is a phenomenon in which loose, saturated, cohesionless soil deposits located beneath the groundwater table lose strength when subjected to intense and prolonged ground shaking. The seismic excitation increases pore water pressure creating a buoyant effect of the loose soil. When liquefaction occurs, building foundations may sink or tilt and differential ground settlement may occur. Other effects include sand boils (ground loss) and lateral spreading if the liquefiable soil is located adjacent to a steep free face. The areas that have the greatest potential for liquefaction are those in which the water table is less than 50 feet below ground surface and the soils are predominately clean, poorly graded sand deposits of loose to medium-dense relative density.

Geocon Project No. S3134-05-01 - 5 - December 3, 2025
The site is not located in a currently established State of California Seismic Hazard Zone for liquefaction.

Based on the subsurface conditions encountered at the site, including predominantly clayey soils and lack of groundwater within the top 50 feet, liquefaction potential is expected to be low during seismic events.

Mitigation and specific design measures with respect to liquefaction is not necessary for the project.

5.4 Expansive Soil
Laboratory Plasticity Index and Expansion Index tests on selected near-surface soil samples indicate low to medium plasticity and corresponding low expansion potential. Mitigation and/or special design considerations with respect to expansive soil is not necessary for the project.

5.5 Soil Corrosion Screening
We submitted a soil sample to Sunland Analytical of Rancho Cordova, California to be tested for pH, resistivity, chloride, and sulfate to generally evaluate the corrosion potential of the soil with respect to proposed subsurface structures. These tests were performed in accordance with California Test Method (CTM) Nos. 643, 422, and 417. The results are presented in Table 5.5A and should be considered for design of underground structures.

Soil with a low pH (higher acidity) is considered corrosive as it can react with lime in cement to leach out soluble reaction products and result in a more porous and weaker concrete. Per Caltrans Corrosion Guidelines (Caltrans, 2021), soil with a pH of 5.5 or lower may be corrosive to concrete or steel in contact with the ground.

Soil resistivity is the measure of the soil’s ability to transmit electric current. Corrosion of buried ferrous metal is proportional to the resistivity of the soil. A lower resistivity indicates a higher propensity for transmitting electric currents that can cause corrosion of buried ferrous metal items. In general, the higher the resistivity, the lower the rate for corrosion. Per Caltrans Corrosion Guidelines (Caltrans, 2021), resistivity serves as an indicator parameter for the possible presence of soluble salts and it is not

included as a parameter to define a corrosive area for structures. A minimum resistivity value for soil less than 1,100 ohm-cm may indicate the presence of high quantities of soluble salts and a higher propensity for corrosion. Based on the laboratory minimum resistivity test results and Caltrans criteria, soil at the location tested does not have a higher propensity for corrosion.

Table 5.5B presents a summary of concrete requirements set forth by the California Building Code (CBC) Section 1904 and American Concrete Institute (ACI) 318 for possible chloride exposure. Chlorides can break down the protective oxide layer on steel surfaces resulting in corrosion. Sources of chloride include, but are not limited to, deicing chemicals, salt, brackish water, seawater, or spray from these sources.

The appropriate Chloride Severity/Exposure Class should be determined by the project designer based on the specific conditions at the location of the proposed structure. Further guidance is provided in ACI 318. Per Caltrans Corrosion Guidelines, soil with a chloride concentration of 500 ppm or higher may be corrosive to steel structures or steel reinforcement in concrete. Based on Caltrans criteria, soil at the location tested is not corrosive with respect to chloride content.

Table 5.5C presents a summary of concrete requirements set forth by CBC Section 1904 and ACI 318 for sulfate exposure. Similar to chlorides, sulfates can break down the protective oxide layer on steel leading to corrosion. Sulfates can also react with lime in cement to soften and crack concrete.

Notes: 1. Maximum water to cement ratio limits are different for lightweight concrete, see ACI 318 for details.

Based on the laboratory test results, the Sulfate Severity is classified as “Not Applicable” and the Exposure Class is S0. The concrete mix design(s) should be developed accordingly. The presence of water-soluble sulfates is not a visually discernible characteristic; therefore, other soil samples from the site could yield different concentrations. Additionally, over time landscaping activities (i.e., addition of fertilizers and other soil nutrients) may affect the concentration.

Geocon does not practice in the field of corrosion engineering and the above information is provided as screening criteria only. If corrosion sensitive improvements are planned, we recommend that further evaluations by a corrosion engineer be performed to incorporate the necessary precautions to avoid premature corrosion on buried metal pipes and metal or concrete structures in direct contact with the soils.

6.0 CONCLUSIONS AND RECOMMENDATIONS

6.1 General

6.1.1 No soil or geologic conditions were encountered during our investigation that would preclude the proposed renovations at the sites as planned, provided the recommendations contained in this report are incorporated into the design and construction of the projects.

6.1.2 Conclusions and recommendations provided in this report are based on our review of referenced literature, analysis of data obtained from our field exploration, laboratory testing program, and our understanding of the proposed development at this time. We should review the project plans as they develop further, provide engineering consultation as needed during final design, and perform geotechnical observation and testing services during construction.

6.2 Seismic Design Criteria

6.2.1 Seismic design of structures should be performed in accordance with the provisions of the 2022 CBC which is based on the American Society of Civil Engineers (ASCE)/Structural Engineering Institute (SEI) publication: ASCE/SEI 7-16, Minimum Design Loads and Associated Criteria for Buildings and Other Structures (ASCE/SEI, 2017). We used the Structural Engineers Association of California (SEAOC) and Office of Statewide Health Planning and Development (OSHPD) web application Seismic Design Maps (https://seismicmaps.org/) to evaluate site-specific seismic design parameters in accordance with ASCE 7-16.

For seismic design purposes, sites are classified as Site Class “A” through “F” as follows:
• Site Class A – Hard Rock;
• Site Class B – Rock;
• Site Class C – Very Dense Soil and Soft Rock;
• Site Class D – Stiff Soil;
• Site Class E – Soft Clay Soil; and
• Site Class F – Soils Requiring Site Response Analysis.

Based on the subsurface conditions at the site, the Site Classification is Site Class “D – Stiff Soil” per Table 20.3-1 of ASCE/SEI 7-16. For the purpose of evaluating code-based seismic parameters for design, we assumed a seismic Risk Category I, II, or III (per the CBC) for the project. Results are summarized in Table 6.2.1.

6.2.3 Conformance to the criteria presented in Tables 6.2.1 and 6.2.2 for seismic design does not constitute any kind of guarantee or assurance that significant structural damage or ground failure will not occur if a maximum level earthquake occurs. The primary goal of seismic design is to protect life and not to avoid structural damage, since such design may be economically prohibitive.

6.3 Soil and Excavation Characteristics

6.3.1 In our opinion, grading and excavations at the site may be accomplished with standard to moderate effort using heavy-duty grading/excavation equipment. We do not anticipate project excavations to generate oversized rock material (greater than 6 inches in dimension).

6.3.2 We anticipate that temporary excavations such as footings and utility trenches may experience sloughing/caving at variable depths. Temporary excavations must meet Cal-OSHA requirements as appropriate. Excavation sloping, benching, the use of trench shields, and the placement of trench spoils should conform to the latest applicable Cal-OSHA standards. The contractor should have a Cal-OSHA-approved “competent person” onsite during excavation to evaluate trench conditions and to make appropriate recommendations where necessary. It is the contractor’s responsibility to provide sufficient and safe excavation support as well as protecting nearby utilities, structures, and other improvements which may be damaged by earth movements.

6.3.3 The excavation support recommendations provided by Cal-OSHA are generally geared towards protecting human life and not necessarily towards preventing damage to nearby structures or surface improvements. The contractor should be responsible for using the proper active shoring systems or sloping to prevent damage to any structure or improvements near underground excavations.

6.3.4 If grading occurs during or after the wet season (typically winter and spring), or in periods of precipitation, in-place and excavated soils will likely be wet. In addition, soil below existing pavements are often wet, regardless of the time of year. Earthwork contractors should be aware of moisture sensitivity of site soils and potential compaction/workability difficulties.

6.3.5 Earthwork and pad preparation operations in these conditions will likely be difficult with low productivity. Often, a period of at least one month of warm and dry weather is necessary to allow the site to dry sufficiently so that heavy grading equipment can operate effectively.

Conversely, during dry summer and fall months, dry clay soils may require additional grading effort (discing, mixing, or other means) to attain proper moisture conditioning.

6.3.6 Based on laboratory testing, in-situ moisture content of site soils ranges from about 8% to 15%, which on average is higher than optimum moisture content, which is approximately 10%. Due to the fine-grained nature of the soils and measured in-situ moisture contents above optimum, additional drying effort to attain moisture contents suitable for compaction should be anticipated regardless of the time of year. Mitigation alternatives may include aerating/drying the exposed soils (assuming favorable weather conditions), or chemical treatment (e.g. lime treatment). Unstable excavation bottoms may require overexcavating 12 to 18 inches and placing geotextile fabric/geogrid covered with aggregate, for stabilization. We can provide specific recommendations during construction based on conditions encountered.

6.4 Materials for Fill

6.4.1 Excavated soils generated from cut operations at the site are suitable for use as fill in structural areas provided they do not contain deleterious matter, organic material, or cementations larger than six inches in maximum dimension.

6.4.2 Import fill material should be primarily granular with a “very low” expansion potential (Expansion Index less than 20), a Liquid Limit less than 50, Plasticity Index less than 15, be free of organic material and construction debris, and not contain rock/cementations larger than six inches in greatest dimension. Import material should also contain sufficient fines to act as a binder (generally 15 percent fines or higher).

6.4.3 Environmental characteristics and corrosion potential of import soil materials should also be considered. Proposed import materials should be sampled, tested, and approved by Geocon prior to its transportation to the site.

6.5 Grading

6.5.1 All earthwork operations should be observed and all fills tested for recommended compaction and moisture content by a representative of Geocon.

6.5.2 References to relative compaction and optimum moisture content in this report are based on the latest American Society for Testing and Materials (ASTM) D1557 Test Procedure.

Structural building pad areas should extend a minimum of five feet horizontally beyond the outside dimensions of structures, including footings and overhangs carrying structural loads.

6.5.3 Prior to commencing grading, a pre-construction conference with representatives of the client, grading contractor, and Geocon should be held at the site. Site preparation, soil handling and/or the grading plans should be discussed at the pre-construction conference.

6.5.4 Site preparation within proposed improvement areas should begin with removal of grass and organic-rich topsoil. Excavations or depressions resulting from site clearing operations, or other existing excavations or depressions, should be restored with engineered fill in accordance with the recommendations of this report.

6.5.5 Proposed improvement areas, cut bottoms, areas to receive fill, or areas left at-grade should be thoroughly scarified at least 10 to 12 inches, moisture conditioned at or near the optimum moisture content, and uniformly compacted to at least 90% relative compaction at or above optimum moisture content. Our representative should observe site clearing, scarification, watering, and re-compaction operations to evaluate performance of the subgrade under compaction equipment loading and to identify any areas that may require additional removals.

6.5.6 Engineered fill should be compacted in horizontal lifts not exceeding eight inches (loose thickness) and brought to final design elevations. Each lift should be thoroughly moisture conditioned at or near optimum moisture content and uniformly compacted to at least 90% relative compaction.

6.5.7 The upper 12 inches of soil subgrade in flatwork / hardscape areas, whether completed at-grade, by excavation, or by filling, should be uniformly moisture-conditioned at or above optimum moisture content and compacted to at least 90% relative compaction.

6.5.8 Final pavement subgrade, whether completed at-grade, by excavation, or by filling, should be uniformly moisture conditioned at or near optimum moisture content, uniformly compacted to at least 95% relative compaction, and be stable. The 95% relative compaction requirement applies to the top six inches of pavement area subgrade; however, underlying materials must be sufficiently compacted and stable. We recommend proof-rolling the subgrade with a loaded water truck (or similar equipment with high contact pressure) to verify the stability of the subgrade prior to placing aggregate base (AB). We note that deeper scarification, moisture-conditioning, and compaction efforts may be required in order to achieve overall stability and compaction.

6.5.9 Underground utility trenches within structural areas should be backfilled with properly compacted material. Pipe bedding, shading, and backfill should conform to the requirements of the appropriate utility authority. Material excavated from trenches should be adequate for

Geocon Project No. S3134-05-01 - 13 - December 3, 2025
use as general backfill above shading provided it does not contain deleterious matter, vegetation or cementations larger than six inches in maximum dimension. Trench backfill should be placed in loose lifts not exceeding eight inches. Lifts should be compacted to a minimum of 90% relative compaction at or above optimum moisture content. Compaction should be performed by mechanical means only; jetting of trench backfill is not recommended.

6.6 Foundations – Spread Footings / CIDH Concrete Piers

6.6.1 The proposed play equipment and shade structures/canopies may be supported on conventional spread footings or CIDH concrete piers. Given the variably granular (sandy) soil conditions in the top 5 feet, spread footings may be preferable since sloughing and caving may occur in CIDH pier excavations.

6.6.2 Spread footings should be at least 18 inches square and be embedded at least 18 inches below lowest adjacent pad grade. Underground utilities running parallel to footings should not be constructed in the zone of influence of footings. The zone of influence may be taken to be the area within 18 inches laterally of the footing, beneath the footings, and within a 1H:1V plane extending out and down from the bottom corner of the footing.

6.6.3 Spread footings may be designed using an allowable “net” soil bearing capacity of 2,000 pounds per square foot (psf) for combined dead plus live loads. This value may be increased by one-third to evaluate all loads, including wind or seismic forces.

6.6.4 Allowable passive pressure used to resist lateral movement of footings may be assumed to be equal to a fluid weighing 300 pounds per cubic foot (pcf). The allowable coefficient of friction to resist sliding of footings is 0.30 for concrete against soil. Combined passive resistance and friction may be utilized for footing design provided that the frictional resistance is reduced by 50%.

6.6.5 A Geocon representative should observe foundation excavations prior to placing reinforcing steel or concrete to observe that the exposed soil conditions are consistent with those anticipated. If unanticipated soil conditions are encountered, foundation modifications may be required.

6.6.6 CIDH concrete piers should have a minimum diameter of 18 inches, a minimum embedment depth of 6 feet, and be designed using an allowable unit skin friction of 400 psf to resist vertical downward loads. An allowable unit skin friction of 275 psf plus the

FOR COUNCIL APPROVAL ONLY

City of Roseville CO-61 Park
Geotechnical Investigation
Geocon Project No. S3134-05-01 - 14 - December 3, 2025
weight of the pier may be used to resist uplift loads. The allowable downward capacity and allowable uplift capacity may be increased by one-third when considering transient wind or seismic loads. Piers should have a minimum center-to-center spacing of at least three pier diameters. The top 12 inches of embedment should be neglected when calculating axial compression and tension capacities.

6.6.7 Allowable passive pressure used to resist lateral movement of the piers may be assumed to be equal to a fluid weighing 300 pcf with a maximum earth pressure of 3,000 psf. The allowable passive pressure may be applied over two pier diameters for isolated piers with a minimum center-to-center spacing of at least three pier diameters. The allowable passive pressure assumes a horizontal surface extending at least 5 feet or three times the surface generating the passive pressure, whichever is greater. The upper 12 inches of embedment should not be included in the design for lateral resistance.

6.6.8 The bottom of pier excavations should be cleaned of loose cuttings prior to the placement of steel and concrete. Experience indicates that backspinning the auger does not remove loose material, and a flat cleanout plate is necessary. Concrete should be placed within the excavation as soon as possible after the auger/cleanout plate is withdrawn to reduce the potential for caving.

6.6.9 A Geocon representative should be present during pier drilling to confirm that subsurface conditions encountered are consistent with those expected. If unexpected conditions are encountered, foundation modifications may be required.

6.7 Concrete Sidewalks and Flatwork

6.7.1 Sidewalk, curb, and gutter within County right-of-way should be designed and constructed in accordance with the latest City of Roseville standards and details as applicable.

6.7.2 On-site exterior concrete flatwork will likely experience seasonal movement. Therefore, some cracking and/or vertical offset should be anticipated. We are providing the following recommendations to reduce distress to concrete flatwork. Recommendations include moisture conditioning subgrade soils and providing adequate construction and control joints.

It should be noted that even with implementation of these measures, slab movement or cracking could still occur.

• Concrete flatwork and sidewalks should be at least six inches thick and may be placed directly on subgrade soil compacted to at least 90 percent relative compaction. If desired, a 4-inch layer of Class 2 AB compacted to 95 percent relative compaction may be placed below the concrete flatwork in order to provide a firm base. In addition, doweling could be provided at joints to reduce the potential for vertical offset. • The upper six inches of subgrade soil for exterior flatwork and sidewalks should be uniformly moisture-conditioned at or above optimum moisture content and compacted to at least 90 percent relative compaction prior to placing AB (if used). • We recommend using construction and control joints in accordance with ACI and/or PCA guidelines. Construction joints that abut building foundations should include a felt strip, or approved equivalent, that extends the full depth of the exterior slab. Exterior slabs should be structurally independent of building foundations except at doorways, where vertical movement could impact doorway operation.

6.8 Pavement - Hot Mix Asphalt

6.8.1 We performed Resistance-Value (R-Value) testing on representative bulk soil sample at the site in accordance with California Test Method (CTM) 301. Our testing resulted in an R-Value of 39. To account for subgrade soil variability resulting from site grading, we recommend using a maximum R-Value of 30 for pavement design.

6.8.2 The project civil engineer should determine the appropriate Traffic Index (TI) for pavement design. Table 6.8.2 provides alternative pavement sections based on the design methods of Caltrans’ Highway Design Manual for various TIs. We can provide additional section designs upon request.

6.8.3 The recommended alternative pavement sections are based on the following assumptions:

1. Subgrade soil has an R-Value of at least 30.

2. Class 2 AB has a minimum R-Value of 78 and meets the requirements of Section 26 of Caltrans’ latest Standard Specifications.

3. Class 2 AB is compacted to 95 percent or higher relative compaction at or near optimum moisture content. Prior to placing HMA, the AB should be proof rolled with a loaded water truck to verify stability.

4. Pavement subgrade should be compacted in accordance with the recommendations presented in this report.

5. HMA should conform to Section 39 of Caltrans’ latest Standard Specifications.

6. Periodic maintenance of HMA pavements is performed.

6.8.4 To reduce the potential for water from landscaped areas migrating under pavement into the AB, consideration should be given to using full-depth curbs in areas where pavement abuts irrigated landscaping. The full-depth curbs should extend at least six inches or more into the soil subgrade beneath the AB. Alternatively, modified drop-inlets that contain weepholes may be used to encourage accumulated water to drain from beneath the pavement.

6.9 Pavement - Rigid Concrete

6.9.1 If rigid Portland Concrete Cement (PCC) pavement is used in automobile and light-truck traffic areas, we recommend that the concrete be at least 6 inches thick. PCC pavement should be underlain by at least 6 inches of Class 2 AB meeting the requirements of Section 26 of Caltrans’ Standard Specifications and compacted to at least 95% relative compaction.

Subgrade soils should be prepared and compacted in accordance with the recommendations of this report.

6.9.2 Steel reinforcement, if used, should be detailed in accordance with PCA, ACI, or similar guidelines.

Alternatively, macro synthetic fibers (Euclid Chemical Tuf-Strand SF or equivalent) mixed into the concrete mix may be considered in lieu of conventional steel reinforcement provided it meets the requirements of ASTM C1116 and ASTM D7508 for Type III Synthetic Fibers.

6.9.3 Adequate dowels should also be used at joints to facilitate load transfer and reduce vertical offset. In addition, the recommendations in Section 6.10 pertaining to adequate drainage apply to concrete pavements, sidewalks, and flatwork, as well as asphalt pavements.

6.9.4 In general, we recommend that concrete pavements be detailed, designed, constructed, and maintained in accordance with industry standards such as those provided by the ACI and PCA.

6.10 Site Drainage and Moisture Protection

6.10.1 Adequate site drainage is critical to reduce the potential for differential soil movement, soil expansion, erosion and subsurface seepage. Under no circumstances should water be allowed to pond adjacent to building foundations. The site should be graded and maintained such that surface drainage is directed away from structures in accordance with the 2022 CBC or other applicable standards. In addition, surface drainage should be directed away from the top of slopes into swales or other controlled drainage devices.

6.10.2 Underground utilities should be leak free. Utility and irrigation lines should be checked periodically for leaks, and detected leaks should be repaired promptly. Detrimental soil movement could occur if water is allowed to infiltrate the soil for prolonged periods of time.

6.10.3 We recommend use of area drains to collect excess irrigation water and transmit it to drainage structures or impervious above-grade planter boxes. In addition, where landscaping is planned adjacent to the pavement or flatwork, we recommend construction of a cutoff wall (deepened curb) along the edge of the pavement/flatwork that extends at least four inches into the soil subgrade below the bottom of the base material.

6.10.4 Experience has shown that even with these provisions, subsurface seepage may develop in areas where no such water conditions existed prior to site development. This is particularly true where a substantial increase in surface water infiltration has resulted from an increase in landscape irrigation.

FIELD EXPLORATION
We performed our geotechnical field exploration on September 9, 2025. Our field exploration program consisted of performing four test pits (TP1 through TP4) at the approximate locations depicted on the Site Plan, Figure 2 and Proposed Development Plan, Figure 3.

The test pits were excavated using a rubber-tire John Deere 310G backhoe equipped with an 18-inch-wide bucket. Upon completion, the test pits were backfilled with the excavated soil.

We visually examined, classified, and logged the subsurface conditions in the test pits in general accordance with the American Society for Testing and Materials (ASTM) Practice for Description and Identification of Soils (Visual-Manual Procedure D2488-17). This system uses the Unified Soil Classification System (USCS) for soil designations. The logs depict soil and geologic conditions encountered and depths at which we obtained samples. The logs also include our interpretation of the conditions between sampling intervals. Therefore, the logs contain both observed and interpreted data. We determined the lines designating the interface between soil materials on the logs using visual observations, drill rig penetration rates, excavation characteristics, and other factors. The transition between materials may be abrupt or gradual. Where applicable, we revised the field logs based on subsequent laboratory testing. Logs of test pits are presented herein.
