CITY OF MILPITAS

AGENDA REPORT
(AR)

Item Title: Approve and Authorize the City Manager to Execute a Stormwater Management Facilities Operation & Maintenance Agreement for BP Products North America Inc. at 1575 Landess Avenue (Staff Contact: Steve Erickson, Engineering Director/City Engineer 408-586-3301)
Category: Consent Calendar-Community Development
Meeting Date: 4/19/2022
Recommendation: Approve and authorize the City Manager to execute a Stormwater Management Facilities Operation and Maintenance Agreement for BP Products North America Inc. for the Gas Station and Convenience Store Project at 1575 Landess Avenue.

Background:

On June 27, 2018, the Property Owner received entitlements from the City allowing for the development of the Property, including the construction of a 3,180 sq. ft. gasoline service station and convenience store, a new canopy structure over existing fuel dispensers, a new trash enclosure, offsite and onsite improvements , landscaping, irrigation, and stormwater treatment measures on a 0.56-acre site located at 1575 Landess Avenue.

In accordance with State Law and the City’s Municipal Regional Stormwater NPDES Permit (“MRP”) issued by the Regional Water Quality Control Board (“RWQCB”), new development and redevelopment projects that create and/or replace 10,000 square feet or more of impervious surface are required to incorporate Low Impact Development (“LID”) post construction stormwater control measures into the project. LID control measures include, for example, bioretention areas, flow-through planters, permeable pavement, infiltration trenches, and tree well filters.

Analysis:

MRP section C.3.h.ii.(1)(a) and Milpitas Municipal Code Title XI Chapter 16 require development project property owners meeting the 10,000 square foot threshold to execute and record a Stormwater Management Facilities Operation and Maintenance Agreement (“Agreement”) with the City for the perpetual operation, maintenance, and annual inspection of LID stormwater treatment facilities installed (Attachment 1).

The BP Arco project constructed stormwater Bio-treatment devices and BP Products North America Inc. will be responsible for the perpetual maintenance and operation of the bio-treatment areas specified in Agreement.

BP Products North America Inc has complied with the LID requirements and has executed the required Agreement, which has been reviewed by the City Attorney as to form and by the City Engineer as to content.

Policy Alternatives:

Alternative 1:

Not approve the Agreement with the City for operation, maintenance and annual inspection of stormwater treatment facilities.

Pros: None

Cons: Not approving the Agreement would cause the project to be not in compliance with the conditions of development and the City’s Municipal Code and would be prohibitive by Federal and State law. 31 Item # C5.

Reason not recommended: To comply with Federal and State law and to allow for the required City annual inspection of installed stormwater Bio-treatment devices, staff recommends approval of the Operations and Maintenance Agreement.

Fiscal Impact:

As required by the Stormwater Management Facilities Operation and Maintenance Agreement, the project developer/owner will pay the City for the required annual inspections of the installed stormwater Bio-treatment facilities.

California Environmental Quality Act:

Recommendation:

Approve and authorize the City Manager to execute a Stormwater Management Facilities Operation and Maintenance Agreement for BP Products North America Inc. Gas Station and Convenience Store project at 1575 Landess Avenue.

I. PROJECT SETTING

I.A. Project Description
The ARCO remodel project proposes to redevelop an existing fueling station on a 0.56-acre site located in a C2 general commercial section at 1575 Landess Avenue in Milpitas, California (APN # 088-36-002). The project will consist of the demolition of an existing convenience store building located on the northwest corner of Landess Avenue and South Park Victoria Drive. The new improvements consist of the construction of a new 3,180 square foot convenience store, new pavement and a new parking lot.

The proposed surface drainage for the site will generally follow the existing runoff pattern.

Drainage is directed away from the new buildings and existing fuel canopy to bio-retention areas for stormwater treatment. The runoff of the replaced impervious surface, including the building rooftops and parking area, will be treated by the bio-retention system. Any overflow from the bio-retention areas will be piped directly to the existing storm drain manhole on South Park Victoria Drive.

Project information and sizing is in the C.3. Data Form included in Appendix A. Harvesting and Use is not considered feasible according to the Screening Worksheet included in Appendix B.

There is a significant low point in the northeast corner that combined with the elevation drop and the location will preclude the use of LID treatment in the surrounding area. The use of a trench drain will minimize the area to 187 square feet. However, this minimal, untreated area represents the necessary grade breaks in front of the existing driveway, which will remain untouched. However, this untreatable impervious area will be covered by an interceptor tree credit for a planted Evergreen tree near the trash enclosure.

Although there are only minimal natural resources associated with this site every effort has been made to maximize storm water BMPs and preserve existing landscaping and trees. Please see Appendix A for further description of project impact.

I.B. Existing Site Condition
The site is currently fully developed (Vicinity Map - Appendix C). It is relatively flat with majority of the site covered by paved area. The existing landscaping areas are extremely limited and the storm runoff is untreated and sheet flows to the streets and landscape areas. 45 Item # C5.

Stormwater Management Plan ARCO Milpitas
I.C. Opportunities and Constraints for Stormwater Control Opportunities:
 Capture onsite stormwater which currently runs to the street untreated and direct it through bio-retention area.
 Landscaping available for planting Interceptor Trees
 Label all drain inlets (in pavement area) with No Dumping - Flows to the Bay stencils.  Cover the new trash enclosure.
 Direct drainage from within the trash enclosure to the sanitary sewer.

Constraints:
 The existing site and proposed site designs are constrained by the size of the lot as requirements for parking and vehicle and fuel truck circulation. In order to meet the require parking and circulation design requirements most of the site must be paved.  The existing site soil is clay to sandy clay loam, a type D soil, as per the Geotechnical Engineering Services Report (Appendix H). This low-permeable soil will limit infiltration.

I.D. Hydromodification Applicability
A review of the HMP Applicability Map for the City of Milpitas indicates that the project sites subwatersheds and catchments are greater than or equal to 65% impervious therefore hydromodification is not applicable for this site.
46 Item # C5.

Stormwater Management Plan ARCO Milpitas
II. SELECTION AND DESIGN OF STORMWATER TREATMENT
BMPs
We have selected a Bio-Retention as the BMP of choice to treat the proposed new impervious areas (building roof, new pavement and new parking lot).  Runoff from each of these areas will pass through bio-retention.  Overflow from both bioretention areas will be directed to new storm drain piping connecting to the existing storm drain line on South Park Victoria Drive.

We have selected an Interceptor Tree for a stormwater treatment credit for the driveway on S.

Park Victoria Avenue that will account for runoff unable to be captured.

II.A. General Characteristics of the Treatment Facilities  The selected treatment facility consists of bio-retention, which is selected to treat the anticipated pollutants of concern for this project.
 Two treatment facilities will be used one southeast and one southwest.  Site drainage and division, utility lines, bio-retention facilities, and details are shown in the Design Drawings included in Appendix E.
 The Operations and Maintenance Plan for the treatment facilities is attached as Appendix G.

II.B. General Characteristics of On-Site Soils
 Infiltration rates of existing onsite soil is 0.02 inches per hour according to the Geotechnical Report included as Appendix H.

IMP Descriptions
DMA 1 and DMA 2 will be treated by bioretention facilities, labeled as IMP 1 and IMP 2, respectively.

IMPs were sized using the Worksheets - Sizing for Flow- and Volume- Based Treatment Measures (Combination Flow and Volume Approach) included in Appendix D. IMP 1 was sized based on DMA 1 specifications and for a ponding depth of 0.5 ft, the surface area will need to be 396 square feet. This surface area will meet the treatment capacity required. IMP 2 was sized based on DMA 2 specifications and showed a surface area of 302.28 square feet and ponding depth of 0.417 ft. The bioretention facility ponding depth was sized at 5 inches and the surface area at 311 square feet, which meets the treatment capacity required. These results are presented on the Water Quality Management Plan in the Design Drawings in Appendix E.

O-1 will be reduced by stormwater credit via an interceptor tree. The 15 gallon Evergreen Sweet Bay tree is located adjacent to the existing driveway in the landscape planter beside the trash enclosure.

The tree is shown on the Water Quality Management Plan and on the Planting Plan (L1), both included in the Design Drawings in Appendix E.

Storm Drain Calculations
Rainfall patterns used for the 10-year storm were based on the Rainfall Intensity Charts for the City of Milpitas. Hydraflow Hydrographs Extension for AutoCAD Civil 3D was used for steady-state storm simulation of the 10-year storm and are included in Appendix F. The flow rate for DMA 1 during a 10- year storm is 0.657 cfs. The flow rate for DMA 2 during a 10-year storm is 0.632 cfs.

Stormwater runoff for DMA 1 and 2 will be treated through the bioretention facilities (IMP 1 and IMP 2, respectively) and then routed through the proposed storm drain pipes. The overflow structure for IMP 2 connects to IMP 1 with the proposed 10 storm drain pipe. The pipe bends once after the fueling canopy before final connection to IMP 1 overflow device. IMP 1 overflow device then connects to the public storm drain line on the other side of South Park Victoria Drive. The connection is made with a 15 RCP Class III at a newly proposed manhole.

For DMA 1, stormwater runoff collection is divided into two segments. The first segment represents 3,180 sqft of roof surface area and 1,120 sqft of the landscaping behind the building. This runoff would amount to 0.2 cfs, which will be contained in the 6 slotted pipe will handle this flow even if half full, equation below:

Mannings Equation: Q=(1.49/n)*A[R^(2/3)]*√ܵ
Where n= 0.010, A= 0.10 ft2, D= 0.5 ft, P = 0.8 Rh = 0.13 (Rh =A/P), S=0.005 Q=0.21 cfs.
50 Item # C5.

Stormwater Management Plan ARCO Milpitas
The second segment represents 7,919 sqft of pavement and sidewalk runoff. When runoff leaves the landscaping from the first segment, it will capture the second segment. Therefore the slotted pipe expands to 8 to accommodate the entire DMA 1 surface runoff of 0.657 cfs. After all is captured it enters IMP 1. Assuming the pipe is flowing more than half full, the 8 storm drain line could handle up to 0.9 cfs at a 6 inch depth of flow as shown in Mannings equation below:
n= 0.010, A= 0.28 ft2, D= 0.66 ft, P = 1.4 Rh = 0.2 (Rh =A/P), S=0.005 Q=0.9 cfs.

For DMA 2, stormwater runoff from pavement flows into IMP 2 via curb cuts, while stormwater runoff from the canopy roof (1,966 sq ft; 0.126 cfs) drains flows through two 4-inch pipes prior to discharging into IMP 2. These pipes connect before discharging into IMP 1. Therefore, a 4 storm drain line flowing full would handle this flow, see equation below: n= 0.010, A= 0.09 ft2, Rh = 0.33 ft/4 =0.08, S=0.005 Q=0.18 cfs.

If stormwater is not infiltrated, runoff will exit IMP 2 though a 10 pipe that travels to IMP 1. Assuming the pipe is flowing full, the 10 storm drain line could handle up to 2.02 cfs as shown in the equation below: n= 0.010, A= 0.55 ft2, Rh = 0.83 ft/4 =0.21, S=0.005 Q=2.02 cfs.

The volume and flow for IMP 2 then combines with the non-infiltrated volume for IMP1; however, after this combination, the storm drain pipe size increases to a 15 storm drain pipe. Assuming the pipe is flowing full, the 15 storm drain line could handle up to 4.3 cfs as shown in the equation below:
n= 0.013, A= 1.23 ft2, Rh = 1.25 ft/4 = 0.31, S=0.0044
Q=4.3 cfs.

Therefore, both the 10 pipe and the 15 pipe size will be sufficiently sized for the 10-year storm event.

The discharge piping containing the treated stormwater runoff was then modeled to determine the hydraulic grade line (HGL). HGL calculations were run in Storm Sewers Extension for AutoCAD Civil 3D and are included in Appendix F. The results indicate the stormwater runoff in a 10-year storm will be contained below ground surface as shown in the table below.

Section IV. Sizing for Flow- and Volume- Based Treatment Measures (Combination Flow and Volume Approach)
For bioretention areas and flow-through planters, the following approach may be used to take into consideration both the flow of stormwater through the planting media and the volume of stormwater in the surface ponding area. Note that the approach assumes that all of the design rainfall becomes runoff, and thus it is appropriate for use where the drainage area to the treatment measure is mostly impervious. Contributing pervious surfaces can be converted to equivalent impervious surface using the procedure outlined in Step 1.

Step 1. Contributing drainage area to the treatment measure: _______ sq. ft.

Is the contributing drainage area 100% impervious? ____ Yes ____ No If yes, skip to Step 2c and fill in the drainage area as the effective impervious area.

Step 2. Determine the effective impervious surface area draining to the treatment measure:
a. Impervious surface area draining to the treatment measure: _______ sq. ft. b. Pervious surface areadraining to the treatment measure: _______ sq. ft.

Effective impervious area = (pervious area × 0.10) + impervious area Effective impervious area = (Step 2.b x 0.10) + Step 2.a Effective impervious area = _______ sq. ft.

Step 3. Determine the required treatment volume using Adapted CASQA Stormwater BMP Handbook Approach (Worksheet Section II.B, Steps 9 and 10). Copy the results here:

Adjusted Unit Basin Storage (UBS) Volume: _______ in.

Water Quality Design (WQD) Volume: _______ cu. ft.

Step 4. Determine the design rainfall intensity (Uniform Intensity Approach, Section III.C, Step 3):

Design Rainfall Intensity: __0.2__ in/hr
Step 5. Assume that the rain event that generates the Unit Basin Storage Volume of runoff occurs at the design rainfall intensity for the entire length of the storm. Calculate the duration of the storm by dividing the adjusted Unit Basin Storage Volume by the design rainfall intensity. In other words, determine the amount of time required for the Unit Basin Storage Volume to be achieved at the design intensity rate.

Duration = UBS Volume (inches) ÷ Rainfall Intensity (inches/hour) Duration = (Step 3) ÷ 0.2 in/hr = _________ hrs.

Step 10. Check to see if the average ponding depth is between 0.5 and 1.0 feet (6 and 12 inches), which is the range of allowable ponding depths in a bioretention facility or flow-through planter (0.5 feet is recommended). If the ponding depth is less than 0.5 feet, the bioretention design can be optimized with a smaller surface area (i.e., repeat Steps 6 through 9 with a smaller surface area). If the ponding depth is greater than 1 foot, a larger surface area will be required (i.e., repeat Steps 6 through 9 with a larger surface area).

Stormwater Management Plan ARCO Milpitas
Means to Finance and Implement BMP Maintenance
Proper operation and maintenance of Stormwater Management Facilities will be the responsibility of the property owner in perpetuity.

The applicant will prepare and submit, for review and approval by Santa Clara County, a Stormwater Control Operation and Maintenance Agreement before sale, transfer, or permanent occupancy of the site. The applicant accepts responsibility for maintenance of stormwater management facilities until such responsibility is transferred to another entity.

It is the responsibility of Owner and the facility management to provide for the regular maintenance of both structural and non-structural BMPs. Owner shall pass on this responsibility to successive owners/restaurant managers to insure that the intent of the Water Quality Management Plan is carried out for the entire life of the site. Non-structural BMPs shall be implemented per the Water Quality Management Plan. Structural BMPs shall be inspected at a minimum of every six months or less as required by Santa Clara County to ensure that the BMPs are in compliance with the regulations set forth in the Water Quality Management Plan.

Structural BMPs shall be cleaned and operational no later than October 1st of each year before the start of the rainy season. Records shall be kept on site indicating when maintenance has been performed on each structural or non-structural BMP. BMP maintenance records shall be made available to County officials upon request.

Owner agrees to annex into a Community Facilities District to be established and to execute and record a covenant running with the land, Stormwater Management Facilities Operation and Maintenance Agreement, and right-of-entry with Santa Clara County.

Summary of Maintenance Requirements
Bio-retentions remove pollutants as the runoff passes through sandy loam and open- graded gravel layers. A perforated pipe under drain conveys treated stormwater to the site storm drain system. Routine maintenance is needed to ensure that flow is unobstructed, that erosion is prevented, and that soils are held together by plant roots and are plants are biologically active. Typical routine maintenance consists of the following:
 Inspect bio-retention for evidence of instability or erosion and correct as necessary. Clear any obstructions and remove any accumulation of sediment.

Examine rock or other material used as a splash pad and replenish if necessary.  Inspect overflow inlets for signs of sediment build up or plugging.  Inspect bioretention area for ponded water. If ponded water does not drain within 2-3 days, till and replace the surface soil and replant.  Observe performance of engineering soil layers in the Bio-retention areas for uniform percolation throughout. If portions of the Bio-retention do not drain at the required 5/hour, the soil layers should be removed and replaced. Remove any debris or accumulations of sediment.
 Examine the vegetation to ensure that it is healthy and dense enough to provide filtering and to protect soils from erosion. Replenish mulch as necessary, remove fallen leaves and debris, prune large shrubs or trees and mow turf areas. Confirm that irrigation is adequate and not excessive. Replace dead plants and remove invasive vegetation.

Stormwater Management Plan ARCO Milpitas
Use of Pesticides
The use of pesticides and quick release fertilizers shall be minimized, and the principles of integrated pest management (IMP) followed:

1. Employ non-chemical controls (biological, physical, and cultural controls) before using chemicals to treat a pest problem.

2. Prune plants properly and at the appropriate time of year.

3. Provided adequate irrigation for landscape plants. Do not over water.

4. Limit fertilizer use unless soil testing indicates a deficiency. Slow-release or organic fertilizer is preferable. Check with municipality for specific requirements.

5. Pest control should avoid harming non-target organisms, or negatively affecting air and water quality and public health. Apply chemical controls only when monitoring indicates that preventative and non-chemical methods are not keeping pests below acceptable levels. When pesticides are required, apply the least toxic and the least persistent pesticide that will provide adequate pest control. Do not apply pesticides on a preschedule basis.

6. Sweep up spilled fertilizer and pesticides. Do not wash away or bury such spills.

7. Do not over apply pesticide. Spray only where the infestation exists. Follow the manufacturers instructions for mixing and applying materials.

8. Only licensed, trained pesticide applicators shall apply pesticides.

9. Apply pesticides at the appropriate time to maximize their effectiveness and minimize the likelihood of discharging pesticides into runoff. With the exception of pre-emergent pesticides, avoid application if rain is expected.

10. Unwanted/unused pesticides shall be disposed as hazardous waste.

Vector Control
Standing water shall not remain in the treatment measures for more than five days, to prevent mosquito generation. Should any mosquito issues arise, contact the Santa Clara Valley Vector Control District (District). Mosquito larvicides shall be applied only when absolutely necessary, as indicated by the District, and then only by a licensed professional or contractor. Contact information for the District is provided below.

1.0 PROJECT INFORMATION

1.1 Project Authorization
Professional Service Industries, Inc. (PSI) is pleased to submit our Geotechnical Engineering Services Report for the proposed AM/PM Fueling Station remodel in Milpitas, California. Our work was performed in general accordance with the BP Geotech Services Scope of Work dated March 1, 2017. Our work was authorized by Ms. Michelle Knapp of BP by issuing a Purchase Order (PO#4532530202, dated October 24, 2017) in response to our geotechnical pricing proposal.

1.2 Site Location and Description
The subject site is a trapezoidal-shaped property measuring about ½ acre in plan area. The site is located at the northwest corner of the intersection of South Park Victoria Drive and Landess Avenue, with a street address of 1575 Landess Avenue in Milpitas, California (see Figure 1 - Site Location Map).

The property is bounded to the north and west by commercial properties, to the south by Landess Avenue followed by commercial properties and to the east by South Park Victoria Drive followed by a commercial property. At the time of our fieldwork, the site was developed with an existing ARCO filling station and AM/PM mini-mart, fuel pumps, a fueling canopy, and paved parking and drive areas (see Figure 2). Based on topographic information obtained from Google Earth, the site is relatively level with elevations ranging from approximately 101 to 106 feet above mean sea level.

1.3 Project Understanding
Based on the scaled Site Plan provided by your office (PM Design, 2017), PSI understands that the existing gas station/mini-mart building is to be demolished and it is proposed to construct a new ARCO station/AM/PM mini-mart as a replacement. We understand from information provided that the new building will consist of a 1-story, 3,180 square foot building, to be located to the northwest of the existing structure. We have assumed that the existing underground storage tanks and canopy will be re-used and that new canopies or USTs will not be needed.

Expected structural loading was not made available at the time this report was prepared, but based on the type of development planned and on our previous experience with similar projects PSI anticipates strip and column footing loads on the order of 3 kips and 30 kips respectively.

Other improvements are likely to include pavements and utilities. Also, for the purposes of this report, we have assumed finish exterior grades to be near (+/- two feet) existing grades. A site plan with the locations of the proposed structures is presented as Figure 2.

Should any of the above information or assumptions made by PSI be inconsistent with the planned construction, we request that you contact us immediately to allow us to make any necessary modifications to our recommendations.

1.4 Purpose and Scope of Services
The purpose of our geotechnical evaluation was to assess the subsurface soil conditions at the site in order to provide appropriate recommendations for site preparation and foundation design.

Our evaluation was in general accordance with the scope of work outlined in the BP Geotech Services Scope of Work dated March 1, 2017.

Our scope of services included 2 Standard Penetration Test (SPT) borings, drilled to depths of up to approximately 21½ to 51½ feet below the existing surface grade (bgs) in the area of the proposed new structure. This report briefly outlines the testing procedures, presents available project information, describes the site and subsurface conditions, and presents geotechnical recommendations regarding the following:

 Site topographic information and surface conditions;
 Review of subsurface conditions including groundwater;  Review of field and laboratory test procedures and test data;  Information on potentially expansive, deleterious, chemically active or corrosive materials;  Figures including a site plan with boring locations and boring logs;  California Building Code (CBC) site class and seismic site coefficients for use in seismic design (CBSC, 2016);
 An assessment of the potential for soil liquefaction during a seismic event;  Site preparation and grading considerations, including recommended fill material characteristics and compaction requirements for general site fill and slab/pavement subgrades, including an assessment as to the suitability of on-site soils for use as fill;  Recommendations pertaining to design and construction of foundations, floor slabs and pavements, including allowable soil bearing pressures, anticipated bearing depths and estimated settlements; and,
 Comments regarding factors that may impact construction and performance of the proposed construction.

The scope of services did not include an environmental assessment for determining the presence or absence of wetlands or hazardous or toxic materials in the soil, bedrock, surface water, groundwater, or air on or below, or around this site. Any statements in this report or on the boring logs regarding odors, colors, and unusual or suspicious items or conditions are strictly for information purposes only.

2.0 SUBSURFACE EXPLORATION

2.1 Site Geology
The subject site is located within a large region known as the Coast Ranges geomorphic province. This province is characterized by extensively folded, faulted, and fractured earth materials. These structural features trend in a northwesterly direction and make up the prominent system of northwest-trending mountain ranges separated by straight-sided sediment filled valleys (CGS, 2002).

The subject site is situated on the alluvial plains near the northern end of the Santa Clara Valley, approximately 4½ miles southeast of the San Francisco Bay. Our review of readily available, pertinent geologic literature (Dibblee, 1973) indicates that the subject site is underlain by late Quaternary aged alluvium (Qa), described as gravel sand and clay.

2.2 Pre-Field Activities
Prior to initiation of field drilling activities, PSI outlined the site and marked the proposed boring locations in white paint, and contacted Underground Service Alert (USA) a minimum of 48 hours prior to beginning work to locate any potential buried utilities. The USA inquiry identification number (or Ticket Number) for the utility locate request was #W729901352-00W. Additionally, PSI hired Subdynamic Locating Services, a subcontract private utility location service, to check the proposed boring locations for underground utilities.

2.3 Subsurface Exploration and Conditions
In order to evaluate soil conditions at the site, PSI advanced 2 Standard Penetration Test (SPT) soil borings within the new building area to depths of about 21½ to 51½ feet below existing grade bgs. Locations of the soil borings, as well as the existing and proposed improvements, are shown on Figure 2.

2.3.1 Standard Penetration Test (SPT) Borings
The SPT borings were drilled by HEW Drilling of East Palo Alto, California with a CME 75 drill rig using hollow-stem auger drilling methods. Boring B-1 and B-2 were advanced in the proposed new building area to depths of approximately 21½ to 51½ feet below the existing ground surface (bgs). At the completion of drilling, the borings were backfilled with soil cuttings and topped with concrete to match the existing surface grades.

During the sampling procedure, Standard Penetration Tests (SPT) were performed in accordance with ASTM D1586 and relatively undisturbed samples were obtained in general accordance with ASTM D3550. The SPT for soil borings were performed by driving a 2-inch diameter split-spoon sampler into the undisturbed subsurface materials located at the bottom of the advanced borehole with repeated blows of a 140-pound hammer falling a vertical distance of 30 inches. The number of blows required to drive the sampler the last 12 inches of an 18-inch penetration depth is a measure of the soil consistency. For ASTM D3550 (California Modified Sampler) the split barrel sampler possesses a 3-inch outside diameter and is driven in the same 106

manner as the SPT. The field blow counts obtained from the California Modified sampler, as indicated in the boring logs, are multiplied by a factor of 0.65 to obtain an approximate correlation to SPT blow counts (SPT-N value). Samples were identified in the field, placed in sealed containers, and transported to the laboratory for further classification and testing.

2.3.2 Soil Description
In the new building area (borings B-1 and B-2), the site was surfaced with about 2 to 3 inches of asphalt underlain by about 3 to 4 inches of aggregate base. Beneath the pavement, the subsurface soil encountered at the boring locations generally consisted of stiff to hard consistency sandy lean clay that extended to a depth of about 40 feet below grade. The sandy lean clay soil was underlain by medium dense clayey sand and very dense poorly graded sand with gravel that extended to the maximum depth explored.

2.3.3 General Boring Notes
The above subsurface information is of a generalized nature to highlight the major subsurface stratification features and material characteristics. The boring logs, included in Appendix A, should be reviewed for specific information at the boring locations. These records include soil descriptions, stratification, penetration resistance, locations of the samples and laboratory test data. The stratification shown on the logs represent the conditions only at the actual location at the time of our exploration. Variations may occur and should be expected between boring locations. The stratification that represents the approximate boundary between subsurface materials and the actual transition may be gradual. It should be noted that, although the test borings are drilled and sampled by experienced professionals, it is sometimes difficult to record changes in stratification within narrow limits, especially at great depths. In the absence of foreign substances, it is also sometimes difficult to distinguish between discolored soils and clean fill soil.

The pavement thicknesses shown on the boring logs are approximate measurements and represent the conditions only at the actual boring locations at the time of our exploration.

Variations may occur and should be expected between boring locations. Additionally, Petromat- type fabric in the pavement section is difficult to discern during drilling and may or may not be present in the existing pavements. As such, the pavement description given in this report is not intended to be used to evaluate the suitability or estimate the quantity for disposal.

2.4 Groundwater
Groundwater was encountered at a depth of approximately 45 feet below grade in boring B-1 at the time of drilling. Groundwater was not encountered within the other exploration either during or upon completion of drilling. Based on a review of the Seismic Hazard Zone Report for the Calaveras Reservoir Quadrangle (CDMG, 2001) we estimate that the historic high groundwater at the site is about 33 feet below grade. As such, groundwater is not expected to impact the proposed construction. It is possible, however, that transient, saturated ground conditions at shallower depths could develop at a later time during periods of heavy precipitation, landscape watering, leaking water lines, or other unforeseen causes. Variations in groundwater levels should be expected seasonally, annually, and from location to location. 107

2.5 Infiltration Rate Evaluation
One infiltration test boring (I-1) was advanced to a depth of about 5 feet bgs in the approximate location indicated on the provided boring location plan (PM Design, 2017). The infiltration boring was advanced to evaluate the feasibility of a proposed bioretention feature. The test depth was selected based on the expected depth of the bioretention feature. The approximate location of the infiltration test boring is indicated on Figure 2.

Once advanced to the test depth, the bottom of the boring was filled with approximately 6 inches of Cemex Lapis Lustre #3 sand. A 5-foot section of perforated PVC piping (slotted well casing) with an inside diameter of approximately 4 inches was installed inside the boring on top of the gravel, with solid piping above, extending upward to the ground surface. Approximately 5 feet of the #3 sand was placed within the annular space around the pipe. The pipe was then filled with a minimum of 5 feet of clean water above the soil to be tested (bottom of the hole) and maintained at a minimum depth of 5 feet for 4 hours to presoak the native soil material.

Following the presoak of the test hole, an infiltration test was performed by filling the pipe with about 3 feet of water and recording the drop in the water level within the pipe at approximate 15- minute intervals for 1 hour. The water level was measured to the nearest 0.01 foot (approximately ⅛ inch) with a flat tape water level meter using the top of the pipe as a reference point. After 1 hour, the process was repeated 2 additional times. The total running time for all three trials was approximately 3 hours. The results of our tests are as follows:

I-1 (5 feet bgs) Test Results –
 An un-factored end of test percolation rate of approximately 0.3 gallons per square foot per day, which is approximately equivalent to 0.02 inches per hour, was obtained.

PSI recommends that a factor of safety of at least 2 be utilized in the design of the any infiltration facility. Local regulatory agencies may also require additional safety factors be applied to the measured infiltration rate and PSI recommends that design rates be determine in general accordance with local requirements.

2.6 Laboratory Evaluation
Selected samples of the subsurface soils encountered were returned to our laboratory for further evaluation to aid in classification of the materials, and to help assess their strength and expansive nature. The laboratory evaluation consisted of visual and textural examinations, moisture and density tests, Atterberg Limit tests, expansion index testing and sieve analysis (percent passing the No. 200 sieve). Sulfate, chloride, pH and resistivity testing were also performed to evaluate the corrosive potential of the site soils. A brief discussion of the laboratory tests performed and a portion of the test results are presented in Appendix B. The remaining test results are shown on the boring logs in Appendix A. Samples that were not altered by laboratory testing will be retained for 30 days from the date of this report and will then be discarded.

3.0 SEISMIC CONSIDERATIONS

3.1 Regional Seismicity
Generally, seismicity within California can be attributed to faulting due to regional tectonic movement. This includes the Hayward Fault, the Calaveras Fault, and most parallel and subparallel faulting within the State. The portion of California which includes the subject site is considered seismically active. Seismic hazards within the site can be attributed to potential groundshaking resulting from earthquake events along nearby or more distant faulting.

According to regional geologic literature (Blake, 2000; USGS, 2016), the closest known late Quaternary fault is the Hayward Fault, located approximately 1 mile northeast of the site. The CDMG Special Studies Zones map (CDMG, 1982) indicates that a mapped trace of the Hayward Fault lies about 0.9 miles northeast of the site. Several potentially active and pre- Quaternary faults also occur within the regional vicinity. The site is subject to a Maximum Magnitude Event of 7.3 Magnitude along the Hayward Fault. The Maximum Magnitude Event is defined as the maximum earthquake that appears capable of occurring under the presently known tectonic framework.

3.2 Seismic Analysis
According to the Alquist-Priolo Special Studies Zones Act of 1972 (revised 1994), active faults are those that have been shown to display surface rupture during the last 11,000 years (i.e., Holocene time). PSI did not observe any mapped faults crossing the site on readily available resources (Dibblee, 1973; USGS, 2016).

The site will be affected by seismic shaking as a result of earthquakes on major active faults located throughout the northern California area. As part of the current, 2016 California Building Code (CBC), the design of structures must consider dynamic forces resulting from seismic events. These forces are dependent upon the magnitude of the earthquake event as well as the properties of the soils that underlie the site. As part of the procedure to evaluate seismic forces, the code requires the evaluation of the Seismic Site Class, which categorizes the site based upon the characteristics of the subsurface profile within the upper 100 feet of the ground surface.

To define the Site Class for this project, we interpreted the results of our soil test borings drilled within the project site and estimated appropriate soil properties below the base of the borings to a depth of 100 feet. The estimated soil properties were based upon data available in published geologic reports as well as our experience with subsurface conditions in the general site area.

Based upon this, the subsurface conditions within the site are consistent within the characteristics of Site Class D (stiff soil profile).

The Site Coefficients, Fa and Fv presented in the above table were also obtained from the noted USGS webpage, as a function of the site classification and mapped spectral response acceleration at the short (Ss) and 1-second (S1) periods, but can also be interpolated from CBC Tables 1613.3.3(1) and 1613.3.3(2). Based on the above values, a Seismic Design Category D is considered appropriate for the site.

3.3 Hazard Assessment
Lurching and Shallow Ground Rupture Evidence of active fault rupture was not observed within the explored areas of the site at the time of our subsurface exploration and as noted above, PSI did not observe any mapped faults crossing the site in readily available resources. As such, the potential for ground rupture from faulting at the site is considered to be low.

Liquefaction Soil liquefaction and seismically-induced settlement typically occur in saturated cohesionless soils; and in clays and plastic silts with low plasticity indexes with moisture contents near their liquid limits, due to cyclic softening where the groundwater is relatively shallow (within 50 feet of the ground surface). During an earthquake, ground shaking causes a rapid increase in the porewater pressure within the soil mass under undrained conditions. The generation of excess porewater pressures causes a corresponding decrease in the soils effective stress, which can result in a sudden loss of soil bearing strength and ground surface settlement within the liquefied (and softened) soil layers. Soil liquefaction potential is generally affected by soil types, mineral contents, ground acceleration, duration of shaking, and frequency content of the earthquake ground motion, among other factors.

The Seismic Hazard Zones map for the Calaveras Reservoir Quadrangle (CDMG, 2001) indicates that the site is not located within a designated liquefaction hazard zone. However, a designated liquefaction hazard zone is located in close proximity to the site. Based on this setting, a detailed liquefaction analysis was performed to assess the liquefaction potential of the site soils. To evaluate the liquefaction potential, the computer software program, LiquefyPro (CivilTech, 2007) was utilized. A ground acceleration (PGAM) of 0.697g and an earthquake 110

magnitude (Mw) of 6.63, both obtained from the USGS website, were incorporated into the analysis. The soil profile identified within Boring B-1 and a groundwater depth of 33 feet (historic high) were also used.

As noted in SP 117A, low plastic silts and clays are potentially susceptible to soil liquefaction only if their plasticity indices are less than 12 and the ratio of their in-situ moisture contents relative to the soils liquid limit is greater than 85%. To assess the liquefaction susceptibility of the site clay soils, laboratory testing was performed and is summarized in the table below.

Sample Moisture
Content (w)
Liquid Limit
(LL)
Plasticity
Index (PI)
w/LL Potentially
Susceptible
B-1 @ 25 feet 9% 32 16 28% No
B-1 @ 35 feet 8% 33 17 24% No

The results of this analysis indicate that the clayey sand soil layer between about 40 to 45 feet below grade is potentially susceptible to soil liquefaction upon application of the design earthquake. The analysis also indicates that a total seismic-induced settlement of about 0.6 inches is possible with an estimated differential settlement of about 0.4 inch over a 40-foot horizontal span. It is our opinion that the magnitudes of estimated total and differential seismic settlement are within tolerable limits and ground modification or other remedial measures are not needed. A copy of the liquefaction analysis is included within Appendix C.

Secondary Liquefaction Effects Based on the relative thickness of the overlaying non- liquefiable soils relative to the thickness of the potentially liquefiable soil, it is our opinion that the potential for surface manifestations (sand boils, loss of bearing, etc.) are very low (Ichihara, 1985). Due to the absence of any nearby channels/free-faces, the limited thickness of the liquefiable soils and the lack of soil with N-values less than 15, the potential for lateral spreading is considered to be nil.

Landsliding and Slope Stability Seismically induced landsliding is not considered a hazard on, or adjacent to the project site due to the absence of significant steep slopes in or around the project area.

4.0 GEOTECHNICAL RECOMMENDATIONS

4.1 General
Soil deposits, generally consisting of very stiff to hard lean clay underlain by medium dense clayey sand and very dense gravelly sands were encountered at the site. Based on the results of our field exploration, the near surface soils appear to be suitable for foundation support provided the recommendations in this report are followed. PSI recommends that the proposed structure be supported by conventional continuous strip footings or isolated spread footings bearing on existing soils compacted to a firm and unyielding state and/or properly compacted Engineered Fill, as recommended in the Site Preparation section of this report.

The proposed construction at the site should be performed in accordance with the following recommendations, the current edition of the California Building Code, and local governmental standards which have jurisdiction over this project. Our recommendations have been developed on the basis of the described project characteristics and subsurface conditions encountered. If there are any changes in these project criteria, including project location on the site, a review should be made by PSI to determine if modifications to the recommendations are warranted.

Once final design plans and specifications are available, a general review by PSI is recommended to check that the evaluations made in preparation of this report are correct and that earthwork and foundation recommendations are properly interpreted and implemented.

4.2 Site Preparation
Initial site preparation should include demolition of the existing building and any other improvement which is not to remain. Removal of the existing structure should include removal of the foundations, floor slab and any other below-grade component. Pavements which are not planned for re-use should also be removed. Existing utilities that are in conflict with the new construction should be removed or re-routed as needed. All debris resulting from the stripping and demolition operations should be legally disposed off-site. Soils disturbed by the demolition of the existing improvements should be removed to undisturbed soil and be stockpiled for future use.

All grading operations should be performed in accordance with our recommendations, the requirements of the current edition of the CBC, and local governmental standards which have jurisdiction over this project.

Following demolition, removal of soils disturbed by the demolition and clearing operations and lowering of grades as needed, we recommend that the building and areas to support new improvements should be proof rolled with a heavy rubber tired piece of construction equipment approved by and in the presence of the Geotechnical Engineer. Any soil that is observed to excessively yield or deflect during the proof rolling operation should be removed to a suitable subgrade as determined by the Geotechnical Engineer.

It is recommended that the exposed subgrade soil, within all areas to receive Engineered Fill or to support surface improvements (new foundation members, slabs and pavements) be scarified to a depth of about 12 inches, be moisture conditioned to about 2 percent above or below the soils optimum moisture content and compacted to a minimum of 90 percent relative compaction (based on ASTM D1557). This earthwork should extend a minimum 5 feet beyond the proposed improvement areas, where feasible.

4.3 Engineered Fill
Engineered Fill material required at this site should not contain rocks greater than 3-inches in diameter or greater than 30 percent retained on the ¾-inch sieve, and should not contain more than 3 percent (by weight) of organic matter or other unsuitable material. The Expansion Index (EI) for the material should not exceed 50. Based on our subsurface investigation, existing on- site soils are generally suitable for use as Engineered Fill, however, this should be confirmed by a PSI representative during grading. Import materials meeting the above requirements should be approved by the Geotechnical Engineer prior to use as Engineered Fill.

Engineered Fill should be compacted to at least 90 percent of the maximum dry density as determined by the modified Proctor (ASTM D1557). The moisture content of Engineered Fill should be maintained at approximately 2 percent above or below the materials optimum moisture content as determined by the same index during compaction. If the Engineered Fill is too dry, water should be uniformly applied across the affected fill area. If the Engineered Fill is too wet, it must be dried. In either event, the Engineered Fill should be thoroughly mixed by disking to obtain relatively uniform moisture content throughout the lift immediately prior to compaction. The upper 12 inches of the pavement subgrade should be compacted to at least 95% of the soils maximum dry density.

Engineered Fill should be placed in maximum lifts of 8-inches of loose material. Each lift of Engineered Fill should be tested by a PSI soils technician, working under the direction of our Project Geotechnical Engineer, prior to placement of subsequent lifts.

Compaction of the backfill should be checked with a sufficient number of density tests by a representative of the Geotechnical Engineer to determine if adequate compaction is being achieved by the contractor. The properly compacted Engineered Fill should extend horizontally outward beyond the exterior perimeter of the foundations a distance equal to the height of fill or 5 feet, whichever is greater, prior to significant sloping. In addition, Engineered Fill should extend horizontally outward beyond the exterior perimeter of the pavements or footings a distance equal to the height of fill, at a minimum, prior to significant sloping. 113

4.4 Excavations
Excavation and construction operations for the foundations may expose the on-site soils to inclement weather conditions. The stability of exposed soils will rapidly deteriorate due to precipitation or the action of heavy or repeated construction traffic. Accordingly, foundation area excavations and pavement subgrade areas should be adequately protected from the elements, and from the action of repetitive or heavy construction loading.

4.4.1 Excavations/Slopes
Any permanent cut or fill slopes should not exceed 2 Horizontal to 1 Vertical (2H:1V).

Excavations extending below a 1H:1V plane extending down from any adjacent footings should be shored for safety. All excavations should be inspected by a representative of the geotechnical engineer during construction to allow any modifications to be made due to variation in the soil types. All work should be performed in accordance with Department of Labor Occupational Safety and Health Administration (OSHA) guidelines. Job site safety is the responsibility of the project contractor.

In Federal Register, Volume 54, No. 209 (October 1989), the United States Department of Labor, Occupational Safety and Health Administration (OSHA) amended its Construction Standards for Excavations, 29 CFR, part 1926, subpart P. This document was issued to better insure the safety of personnel entering trenches or excavations. It is mandated by this federal regulation that excavations, whether they be utility trenches, basement excavations, or footing excavations, be constructed in accordance with the new OSHA guidelines.

The contractor is solely responsible for designing and constructing stable, temporary excavations and should shore, slope, or bench the sides of the excavations as required to maintain stability of both the excavation sides and bottom. The contractors responsible person, as defined in 29 CFR Part 1926, should evaluate the soil exposed in the excavations as part of the contractors safety procedures. In no case should slope height, slope inclination, or excavation depth, including utility trench excavation depth, exceed those specified in local, state, and federal state regulations.

We are providing this information solely as a service to our client. PSI does not assume responsibility for construction site safety or the contractors or other parties compliance with local, state, and federal safety or other regulations.

4.4.2 Utility Trench Excavation and Backfill
Excavation excavations should be made in accordance with applicable Federal and State Occupational Safety and Health Administration regulations. Utility trenches at the site may need to be sloped or shored from the ground surface due to the potential for caving, dependent upon the depth of new utilities. Actual inclinations will ultimately depend on the soil conditions encountered during earthwork. While we may provide certain approaches for trench excavations, the contractor should be responsible for selecting the excavation technique, monitoring the trench excavations for safety, and providing shoring, as required, to protect personnel and adjacent improvements. The information provided below is for use by the owner 114

and engineer and should not be interpreted to mean that PSI is assuming responsibility for the contractors actions or site safety. The soils encountered in our subsurface explorations may be classified as Type B soil according to the most recent OSHA regulations and may be sloped, without shoring at no steeper than 1H:1V for temporary excavations. In our opinion, excavations should be safely sloped or shored. The contractor should be aware that excavation and shoring should conform to the requirements specified in the applicable local, state, and federal safety regulations, such as OSHA Health and Safety Standards for Excavations, 29 CFR Part 1926, or successor regulations. We understand that such regulations are being strictly enforced, and if not followed, the contractor may be liable for substantial penalties.

Excavation and construction operations may expose the on-site soils to inclement weather conditions. The stability of exposed soils may deteriorate due to a change in moisture content or the action of heavy or repeated construction traffic. Accordingly, foundation and pavement area excavations should be protected from the elements and from the action of repetitive or heavy construction loadings.

Utility trenches below the slab, footings and pavement areas should be backfilled with engineered fill.

4.5 Foundations

4.5.1 Shallow Building Foundations
Following demolition and site preparation, as recommended in Section 4.2, it is our opinion that conventional continuous and isolated spread footings are suitable for the support of the proposed structure. All footings should be supported by suitable bearing existing soils and/or by properly compacted Engineered Fill. Continuous footings should be founded at least 18 inches below lowest adjacent finished grade and have a minimum width of 18 inches. Isolated spread footings should be at least 24 inches wide and supported at a depth of 18 inches below the lowest adjacent grade. Footings with the above recommended minimum dimensions and with subgrade prepared in accordance with section 4.2 of this report may be designed for an allowable bearing pressure of 3,000 pounds per square foot (psf). The allowable soil bearing pressure may be increased by one-third for loads of short duration, including wind and seismic forces. Appropriate foundation reinforcement should be provided in accordance with the Structural Engineers design.

Horizontal loads acting on shallow foundations are resisted by friction along the foundation base and by passive pressure against the footing face, which is perpendicular to the line of applied force. The coefficient of friction between the base of the footing and the subgrade soils may be assumed to be 0.30. A passive soil resistance equal to a uniform pressure of 250 psf may be used for compacted soil or firm native soil against the face of the footing (assuming a level ground surface).

The foundation excavations should be observed by a representative of PSI prior to steel or concrete placement to assess that the foundation materials are capable of supporting the design loads and are consistent with the materials discussed in this report. Soft or loose soil 115
Item # C5.

PSI Project No. 575-1284
December 13, 2017

Page 13 ends

zones encountered at the bottom of the foundation excavations should be removed and replaced with Engineered Fill or recompacted in-place, as recommended by the geotechnical engineer.

After opening, foundation excavations should be observed and concrete placed as quickly as possible to avoid exposure of the foundation bottoms to wetting and drying. Surface run-off water should be drained away from the excavations and not be allowed to pond. If possible, the foundation concrete should be placed during the same day the excavation is made. If it is required that foundation excavations be left open for more than one day, they should be protected to reduce evaporation or entry of moisture.

We estimate that foundations designed constructed in accordance with the above recommendations will experience a total static settlement of less than 1-inch with a differential settlement of less than ½-inch over a 40-foot span within the building area. While settlement of this magnitude is generally considered tolerable for structures of the type proposed, the design of masonry walls should include provisions for liberally spaced, vertical control joints to minimize the effects of cosmetic cracking.

4.5.2 Canopy Foundations
It is PSIs opinion that any new canopy may be supported by shallow foundations or drilled piers.

Shallow canopy foundation elements should be founded on suitable in-situ soils, compacted to a firm and unyielding state (as determined by PSI) or Engineered Fill and may also be dimensioned based on an allowable soil bearing pressure of 3,000 psf, provided they are embedded at least 2 feet below existing and finish site grades. This recommended allowable soil bearing pressure may be increased by ⅓ for temporary seismic or wind loading.

If drilled piers are to be utilized for canopy foundation elements they should consist of an augured shaft having typical diameters of approximately 12 to 60 inches in diameter. They are drilled to a design depth and filled with reinforced concrete. Design parameters related to drilled pier foundations have been prepared based on the field explorations, further observation of the selected bulk samples in the laboratory, published references, and engineering judgment. In general, the design parameters were developed from the observed material type and the SPT data collected.

Piers installed in accordance with the recommendations stated above are calculated to provide an allowable capacity are shown in the table below. Piers should be a minimum of 5 feet deep and skin friction within the upper 2 feet should be neglected. PSI will need observe the subgrade conditions prior to rebar and concrete placement for the piers. Pier calculations were made using Terzaghi and Peck (1967) for cohesive soils, incorporating a factor of safety of 3.0 for end bearing capacity and 2.5 for skin friction.

PSI recommends that the drilling contractor review the field exploration logs of this report before starting excavations for the drilled piers. Though not anticipated, if groundwater or sloughing soils are encountered, it should be expected that the advancement of casing and placement of concrete will be more difficult and special measures will be required to prevent caving. A representative of the Geotechnical Engineer should be on site to observe and document the installation of the deep foundation system.

When the drilling processes are completed for the pier, the reinforcing steel and the concrete should be placed immediately after the final cleanout pass is conducted on the base. The tremie method of concrete placement should be adopted when placing concrete below the groundwater table to prevent segregation of the concrete materials. If concrete is placed by the free-fall method into a dry excavation, it should be placed to avoid contact with the excavation sidewalls to prevent segregation. During simultaneous concrete placement and casing removal operations, sufficient concrete should be maintained inside the casing to offset the hydrostatic head of the ground water outside the casing and minimize the intrusion of soil into the concrete.

Concrete placed in the pier excavations should have a slump in the range of 7 to 9 inches to reduce the potential for the formation of voids as the temporary pier casing is extracted. The concrete mix should be designed to attain the required 28-day design strength when placed at this slump. PSI should be retained to observe and document the drilled pier construction and to evaluate whether the subsurface and pier bearing conditions are as anticipated in this report.

The contractor should submit their procedures for drilled pier installation to the Geotechnical Engineer for approval prior to the start of the drilled pier construction.

We estimate that the shallow foundations or piers will experience less than 1 inch of immediate, post-construction settlement within the area of the structures supported on pipe piers, with less than ½ inch of differential settlement between piers with a lateral surface distance of 40 feet apart from each other.

4.6 Concrete Floor Slab
Concrete slab-on-grade floors can be supported on properly compacted existing soil and/or Engineered Fill after site preparation and fill placement procedures, as described in previous sections of this report, are complete.

The slab section may be designed by the structural engineer using a modulus of subgrade reaction of 125 pounds per square inch per inch and assuming a low expansion potential, based on values typically obtained from 1-foot by 1-foot plate load tests. However, depending on how the slab load is applied, the value may need to be geometrically modified. The value should be adjusted for larger areas using the following expression for cohesive and cohesionless soil:

Modulus of Subgrade Reaction, ks = for cohesive soil; and, ks = k *( )2 for cohesionless soil
where: ks = coefficient of vertical subgrade reaction for loaded area; k = coefficient of vertical subgrade reaction for a 1 by 1 square foot area; and, B = width of area loaded, in feet.

Based on geotechnical considerations, it is recommended that the interior slabs be at least 4 inches in thickness, and reinforced in accordance with the Structural Engineers requirements. Care should be taken by the contractor to ensure that the reinforcement is placed and maintained at slab mid-height. Floor slabs should be suitably reinforced and jointed so that a small amount of independent movement can occur without causing damage.

Slabs should be underlain by capillary break material that is at least 4 inches thick, consisting of clean sand or gravel. In moisture-sensitive flooring areas or areas used to store moisture-sensitive materials, such as carpeted or linoleum covered areas, a 10-mil visqueen moisture retarder should be placed beneath the slab at mid-height within the capillary break material. The visqueen sheet should be sealed along the edges to prevent lateral migration of soil moisture from adjacent non- visqueen areas. Prior to placement of clean sand and slab-on-grade, the visqueen sheet should be thoroughly inspected for cracks, punctures, tears, and holes. If necessary, the visqueen should be replaced or patched to assure a fully functional entity.

Some minor cracking of slabs can be expected due to shrinkage. The potential for this slab cracking can be reduced by careful control of water/cement ratios in the concrete. The contractor should take appropriate curing precautions during the pouring of concrete in hot weather to reduce cracking of slabs. We recommend that a slipsheet (or equivalent) be utilized if grouted fill, tile, or other moisture-sensitive floor covering is planned directly on concrete slabs. All slabs should be designed in accordance with structural considerations. The floor slab should be liberally jointed in accordance with ACI guidelines to help control cracking, resulting from differential movement and concrete shrinkage.

Care should be taken that the grades slope away from the building and landscaping with irrigation is not placed adjacent to the building. Surface water should not be allowed to migrate under the building.

4.7 Drainage Considerations
Surface water must not be allowed to pond adjacent to the foundations. To preclude drainage problems, we recommend continuous roof gutters for the proposed structures. We recommend that roof drains be connected to a tight-line pipe leading to storm drain facilities. Pavement surfaces and open space areas should be sloped such that surface water runoff is collected and routed to suitable discharge points. We also recommend that ground surfaces adjacent to buildings be sloped to facilitate positive drainage away from the buildings. It should be noted that the subsurface (retaining wall) drainage and surface drainage systems must be kept separate.

A positive slope gradient of 2 percent down and away from the building perimeter should be applied to the finished subgrade (inclusive of topsoil). This slope should extend no less than 5 feet away from the outside building perimeter, with drainage swales provided to remove runoff from around the structure. Any utility trench that enters the perimeter of a structures should be excavated with a slight slope down and away from the perimeter of the structure.

Landscaped or planted areas should not be placed within 10 feet of the footings of the proposed structures. Where concrete flat work such as sidewalks are placed next to the structure, concrete should be placed adjacent to the foundation to prevent a planter strip that would trap surface water between the foundation and the sidewalk. For vegetation planted near the buildings, plants that require very little moisture should be used. Irrigation systems (drip and/or sprinkler heads) should not direct water where it could saturate foundation soil.

4.8 Pavement Recommendations
Preparation of the subgrade soils for new pavements should be prepared in general accordance with the site preparation recommendations (Section 4.2) including scarification and recompaction. While specific traffic loads and volumes for the project have not been provided, we are providing recommended light-duty and medium to heavy-duty pavement sections, which have been successfully utilized for this type of development in the project area with similar traffic loading.

For these preliminary pavement sections, we have assumed an R-value of 15 for the site subgrade soils and a Traffic Index of 4.5 and 6.5 for the light duty and heavy-duty sections, respectively. R-value testing should be performed on the actual pavement subgrade material at the time of site grading.

Light Duty (Automobile Parking; TI=4.5)
3 inches Asphalt Concrete (Caltrans Standard Specs. Section 39) over 7 inches Class II Aggregate Base (Caltrans Standard Specs. Section 26)

Heavy Duty (Entrance and Drive Lanes; TI=6.5)
3½ inches Asphalt Concrete (Caltrans Standard Specs. Section 39) 12½ inches Class II Aggregate Base (Caltrans Standard Specs. Section 26)

A rigid pavement section merits consideration for areas to receive relatively high concentrated sustained loads such as trash dumpster enclosures. For these areas, we recommend a minimum concrete thickness of 6 inches over 4 inches of compacted aggregate base. The concrete used for rigid pavement should have a minimum 28-day flexural strength of 600 psi and a maximum slump of 4 inches. The subgrade should be prepared as described in the Site Preparation section above. Pavement joints, reinforcing, and details should be designed in accordance with applicable American Concrete Institute (ACI) standards.

All aggregate base and the upper 12 inches of subgrade should be compacted to at least 95 percent of the maximum dry density as determined by ASTM Designation D1557 or to a firm and unyielding state as determined by PSI. All materials and methods of construction should conform to good engineering practices and be in conformance with the requirements of the local jurisdiction.

4.8.1 General Pavement Notes
The above recommended pavement sections represent minimum design thicknesses and, as such, periodic maintenance should be anticipated. Also, these recommended pavement sections should be confirmed or modified by your Civil Engineer, based on actual traffic and the owners requirements. The pavement section materials and construction should comply with the Caltrans Standard Specifications and local municipality requirements.

Where pavement areas are adjacent to heavily watered landscaping areas, we recommend some measure of moisture control be taken to prevent the subgrade soils from becoming saturated. It is recommended that the concrete curbing adjacent to the landscape areas extend into the prepared subgrade to reduce the potential for irrigation water to saturate subgrade soils.

Note that the pavement thicknesses shown on the boring logs are approximate measurements and represent the conditions only at the actual boring locations at the time of our exploration.

Variations may occur and should be expected between boring locations. Additionally, Petromat- type fabric in the pavement section is difficult to discern during drilling and may or may not be present in the existing pavements. As such, the pavement description given in this report is not intended to be used to estimate the quantity for disposal, if necessary. 120

4.9 Corrosivity
Testing was performed to evaluate the corrosivity of the on-site soils and the potential for attack on concrete and subsurface utility pipes, specifically cast iron and ductile iron. The testing included pH, sulfate, chloride and electrical resistivity. The results of the chemical analysis are as follows:

Boring
Number
Sample Depth
(feet)
pH Resistivity
(ohm-cm)
Water Soluble
Sulfates (ppm)
Water Soluble
Chlorides (ppm)
B-1 1 to 4 7.9 1,000 130 35.2
ppm = parts per million
Concrete mix designs should follow the minimum requirements of the California Building Code.

Laboratory testing of selected soil samples indicates that the on-site soils possess a negligible sulfate exposure, indicating a low degree of corrosivity with respect to concrete. Based on this result, it is our opinion that special sulfate-resistant concrete mix designs are not warranted and that the use of Type I or II cement is suitable for concrete in contact with on-site soils. Final concrete mix designs should be evaluated after sulfate tests have been performed on the actual subgrade material.

Corrosivity testing was also performed to determine whether the on-site soils have the potential to attack subsurface utility pipes, specifically cast iron and ductile iron. Based on the resistivity test results, the soils are characterized as being highly corrosive to cast iron or ductile iron piping (Roberge, 2000). PSI does not practice in the field of corrosion engineering. We recommend that a qualified corrosion engineer be consulted to determine if special corrosion protection is warranted for this site. Testing for corrosivity of any fill soils should be conducted during site grading to verify our recommendations.

4.10 Construction Monitoring
It is recommended that PSI be retained to examine and identify soil exposures created during project construction to document that soil conditions are as anticipated. We further recommend that any Engineered Fills be continuously observed and tested by our representative to evaluate the thoroughness and uniformity of their compaction. If possible, samples of fill materials should be submitted to our laboratory for evaluation prior to placement of fills on site. Costs for the recommended observations during construction are beyond the scope of this current consultation.

After the plans and specifications are more complete, the geotechnical engineer should be retained and provided the opportunity to review the final design plans and specifications to check that our engineering recommendations have been properly incorporated into the design documents.

5.2 Limitations
The recommendations contained in this report are based on the available subsurface information obtained by PSI, and design details furnished for the proposed project. If there are any revisions to the plans for this project, or if deviations from the subsurface conditions noted in this report are encountered during construction, PSI should be notified immediately to determine if changes in the foundation recommendations are required. If PSI is not retained to perform these functions, PSI will not be responsible for the impact of those conditions on the project.

PSI did not provide any service to investigate or detect the presence of moisture, mold or other biological contaminants in or around any structure, or any service that was designed or intended to prevent or lower the risk of the occurrence of the amplification of the same. Client acknowledges that mold is ubiquitous to the environment with mold amplification occurring when building materials are impacted by moisture. Client further acknowledges that site conditions are outside of PSIs control, and that mold amplification will likely occur, or continue to occur, in the presence of moisture. As such, PSI cannot and shall not be held responsible for the occurrence or recurrence of mold amplification.

Services performed by PSI for this project have been conducted with that level of care and skill ordinarily exercised by members of the profession currently practicing in this area. No warranty, expressed or implied, is made.

GENERAL NOTES

SAMPLE IDENTIFICATION

Page 1 of 2 ends

The Unified Soil Classification System (USCS), AASHTO 1988 and ASTM designations D2487 and D-2488 are used to identify the encountered materials unless otherwise noted. Coarse-grained soils are defined as having more than 50% of their dry weight retained on a #200 sieve (0.075mm); they are described as: boulders, cobbles, gravel or sand. Fine-grained soils have less than 50% of their dry weight retained on a #200 sieve; they are defined as silts or clay depending on their Atterberg Limit attributes. Major constituents may be added as modifiers and minor constituents may be added according to the relative proportions based on grain size.

LABORATORY TEST RESULTS
Laboratory Testing Program

Laboratory tests were performed on representative soil samples to determine their relative engineering properties. Tests were performed in general accordance with test methods of the American Society for Testing Materials or other accepted standards. The following presents a brief description of the various test methods used.

Classification - Soils were classified visually according to the Unified Soil Classification System. Visual classifications were supplemented by laboratory testing of selected samples in general accordance with ASTM D2487. The soil classifications are shown on the boring logs in Appendix A.

In-Situ Moisture / Density - The in-place moisture content and dry unit weight of selected samples were determined using relatively undisturbed samples from the linear rings of a 2.38- inch I.D. modified California Sampler. The moisture content of representative SPT samples was also determined. The dry unit weight and moisture contents are shown on the boring logs.

Expansion Index - Expansion Index testing was performed on a representative sample of the on-site soils, remolded and surcharged to 144 pounds per square foot in general accordance with the Uniform Building Code Standard No. 18-2. The result of this test is provided in the text of this report and below.

Atterberg Limits – The liquid limit, plastic limit, and plasticity index of selected representative samples were determined in accordance with ASTM D4318. The liquid limit and plastic indices are shown on the Boring Logs and below.

Material Finer than #200 – Select samples from the borings were analyzed for grain size in general conformance with ASTM C 117. In general, oven dried samples are passed through a

0.75 µm (#200) sieve by adding water and washing fine grained material through the screen then drying back the retained material and comparing it to the total sample mass to find the percent retain and passing the #200 sieve. The percent passing the #200 sieve is shown on the Boring Logs.

Soil Sulfate / Chloride Test – In order to estimate the concrete degradation potential of soils, the soluble sulfate and chloride content of a representative sample of the on-site soil, provided in the text of this report, was determined in accordance with EPA Test Method 300.0.

pH (Potential of Hydrogen) – The measure of acidity or alkalinity of a material is referred to as the pH factor, which increases with alkalinity and decreases with acidity. The corrosivity potential of iron increases with low pH (4-5) while the corrosivity potential of copper increases with high pH (10-11). The pH value of a representative sample of the on-site soil, provided in the text of this report, was determined in accordance with EPA Test Method 9045B.

Resistivity – The electrical resistivity of a soil is a measure of its resistance to electrical current flow. Corrosion of buried ferrous metals is an electrochemical process which is related to the flow of electrical current from the metal to the soil. Lower electrical resistivity (higher currents) result from higher moisture and chemical contents in the soil. Resistivity is minimal when the soil is saturated. The resistivity of a representative sample of the on-site soil, provided in the text of this report, was determined in accordance with AASHTO Test Method T 288-91.

AGENDA REPORT
(AR)

Item Title: Approve and Authorize the City Manager to Execute a Stormwater Management Facilities Operation & Maintenance Agreement for Robinson Oil Corporation at 1787 South Main Street (Staff Contact: Steve Erickson, Engineering Director/City Engineer 408-586-3301)
Category: Consent Calendar-Community Development
Meeting
Date:
4/19/2022
Recommendation: Approve and authorize the City Manager to execute a Stormwater Management Facilities Operation and Maintenance Agreement for Robinson Oil Corporation for the Gas Station and Convenience Store Project at 1787 South Main Street.

Background:

On October 25, 2017, the Planning Commission approved Site Development Permit No. SD16-0007, Conditional Use Permit No. UP17-0026, and Variance No. VA17-0002 allowing the development of the Property, including the construction of a 3,780 square foot canopy structure over the fuel dispensers, a new trash enclosure, offsite and onsite improvements , landscaping, irrigation , and stormwater treatment measures on a 0.68-acre site located at 1787 South Main Street.

Analysis:

MRP section C.3.h.ii.(1)(a) and Milpitas Municipal Code Title XI Chapter 16 require development project property owners meeting the 10,000 square foot threshold to execute and record a Stormwater Management Facilities Operation and Maintenance Agreement (“Agreement”) with the City for the perpetual operation, maintenance, and annual inspection of the LID stormwater treatment facilities (Attachment 1).

The Robben Robbie Gas Station #66 project constructed stormwater Bio-treatment devices and Robinson Oil Corporation will be responsible for the perpetual maintenance and operation of the bio-treatment areas specified in Agreement. Robinson Oil Corporation has executed the required Agreement which has been reviewed by the City Attorney as to form and by the City Engineer as to content.

Policy Alternatives:

Alternative 1:

Not approve the Operations and Maintenance Agreement with the City for operation, maintenance and annual inspection of stormwater treatment facilities.

Pros: None

Cons: Not approving the Agreement would cause the project to be not in compliance with the conditions of development and the City’s Municipal Code and would be prohibitive by federal and state law. 161 Item # C6.

Reason not recommended: To comply with Federal and State law and to allow for the on-going maintenance and City annual inspection of installed stormwater Bio-treatment devices, staff recommends approval of the Agreement.

Fiscal Impact:

California Environmental Quality Act:

The City Council’s approval of the agreement was already reviewed under the California Environmental Quality Act (CEQA) at the time the City Council approved the entitlements for the project thru an initial environmental assessment. The Planning Division completed an environmental assessment for the project in accordance with the California Environmental Quality Act (CEQA), which assessment determined that the proposed project is exempt from further CEQA review, pursuant to State CEQA Guidelines Section 153 02 for “Replacement and Reconstruction,” as project consists of a service station, fuel dispensers, canopy structure, parking lot, trash enclosure and landscape, similar to the property’s previous use as a service station and auto repair establishment. The project is also exempt under State CEQA Guidelines Section 15303 for “New Construction or Conversion of Small Structures,” as the project is construction of a commercial use not exceeding 10,000 square feet in floor area in an urbanized area and does not involve the use of significant amounts of hazardous substances. Furthermore, none of the exceptions to the categorical exemptions stated in State CEQA Guidelines section 15300.2 apply. On this basis, the City Council relies on the previous CEQA review conducted in approving this agreement.

Recommendation:

Approve and authorize the City Manager to execute a Stormwater Management Facilities Operation and Maintenance Agreement for Robinson Oil Corporation Gas Station and Convenience Store Project at 1787 S Main St.

Figure 1

II.B. Existing Site Features and Conditions
The existing site is formerly a 76 Gas Station that consisted of a service building, fuel pumps, and underground storage tanks. The site has been since completely demolished and is currently barren.

The site is relatively flat with a 2% slope. The existing stormwater currently infiltrates or surface flows to the street. There is a street frontage drain inlet located on South Main Street to collect stormwater surface flow.

There are no wetlands or watercourses nearby. The closest watercourse is Coyote Creek, which is located approximately 3,900 feet to the west.

Project site is surrounded by paved street frontage at the south and east, commercial at the north and west.
178
Item # C6.

ROTTEN ROBBIE #66 PAGE 3 OF 7 SEPTEMBER 11, 2018
II.C. Opportunities and Constraints for Stormwater Control The project site historically drains to South Main Street; the proposed design will maintain the same overland flow. As such, bio retention systems will be installed at the low points of the project site to receive the stormwater before releasing to existing storm drain system.

Landscape buffers are along the entire perimeter of the site which will allow for self-treating and infiltration.

Proposed use for this site is a gas station that will be 25% pervious and 75% impervious. Stormwater generated from pollutants from vehicular circulation will be captured in bio-retention areas to be treated prior to release into the storm drain system.

The soil conditions of the site are not ideal for infiltration. A soils report prepared by Korbmacher Engineering, dated February 15, 2018, indicated site soils as clay with a low infiltration rate. Available groundwater was encountered at approximately 20 feet below ground surface.

III. Low Impact Development Design Strategies
III.A. Optimization of Site Layout
III.A.1. Limitation of development envelope
Site limitations include proximity of building structure foundations, and underground storage tanks near bio-retention areas. Additionally, the proposed use of the project site is as a gas station. Fueling areas require that stormwater be diverted away via grade breaks, interception swale, or other means.

III.A.2. Preservation of natural drainage features
Drainage pattern shall maintain existing overflow route. Replacement of pervious surface with impervious will be addressed via bio-retention areas to be used for infiltration.

III.A.3. Setbacks from creeks, wetlands, and riparian habitats There are no creeks, wetlands, or riparian habitats near the project site.

III.A.4. Minimization of imperviousness
Parking areas have been minimized as much as feasible to minimize imperviousness.

III.A.5. Use of drainage as a design element
Landscape areas will assist in stormwater infiltration. Additionally, grading is proposed to be diverted from fueling area via grade breaks.

III.B. Use of Permeable Pavements
No permeable pavements are proposed.

III.C. Dispersal of Runoff to Pervious Areas
All stormwater runoff will be diverted to bio-retention areas. 179
Item # C6.

ROTTEN ROBBIE #66 PAGE 4 OF 7 SEPTEMBER 11, 2018
III.D. Stormwater Control Measures
Control measures include bio-retention areas that will infiltrate and have a bypass overflow system. The convenience store and fuel canopy will drain to the bio-retention areas via overland flow and bubble-up riser’s.

VI. Stormwater Facility Maintenance
VI.A. Ownership and Responsibility for Maintenance in Perpetuity Owner shall execute any necessary agreements, and accept responsibility for operation and maintenance of facilities until that responsibility is formally transferred.

VI.B. Summary of Maintenance Requirements for Each Stormwater Facility The following activities should be scheduled at least annually. The frequency should be adjusted in response to the needs of each particular facility.

Clean up. Remove any soil or debris blocking planter inlets or overflows. Remove trash that typically collects near inlets or gets caught in vegetation.

Prune or cut back plants for health and to ensure flow into inlets and across the surface of the facility. Remove and replant as necessary. When replanting, maintain the design surface elevation and minimize the introduction of soil.

Control weeds by manual methods and soil amendment. In response to problem areas or threatening invasions, corn gluten, white vinegar, vinegar-based products such as Burnout, or non-selective natural herbicides such as Safer’s Sharpshooter may be used.

Add mulch. Aged mulch, also called compost mulch, reduces the ability of weeds to establish, keeps soil moist, and replenishes soil nutrients. Mulch may be added from time to time to maintain a mulch layer thickness of 1" to 2", but only if the underlying soil surface beneath the mulch layer is a minimum 6" below the overflow elevation, consistently throughout the surface area of the facility.

Check signage. Remove graffiti and replace if necessary.

Check irrigation, if any, to confirm it is adequate but not excessive.

Landscape maintenance personnel should be aware of the following:

Do not add fertilizer to bioretention facilities. Compost tea, available from various nurseries and garden supply retailers, may be applied at a recommended rate of 5 gallons mixed with 15 gallons of water per acre, up to two weeks prior to planting and once per year between March and June. Do not apply when temperatures are below 50°F or above 90°F or when rain is forecast in the next 48 hours.

What is an Impervious Surface?
An impervious surface is a surface covering or pavement that prevents the land’s natural ability to absorb and infiltrate rainfall/stormwater. Impervious surfaces include, but are not limited to rooftops, walkways, paved patios, driveways, parking lots, storage areas, impervious concrete and asphalt, and any other continuous watertight pavement or covering. Pervious pavement, underlain with pervious soil or pervious storage material (e.g., drain rock), that infiltrates rainfall at a rate equal to or greater than surrounding unpaved areas OR that stores and infiltrates the water quality design volume specified in Provision C.3.d of the Municipal Regional Stormwater Permit (MRP) is not considered an impervious surface.
