Staff ReportPREPARED BY : MATT MORLEY DIRECTOR OF PARKS AND PUBLIC WORKS Reviewed by: Assistant Town Manager Town Attorney Finance MEETING DATE: 09/0 6/16 ITEM NO : 4 COUNCIL AGENDA REPORT DATE: AUGUST 23, 2016 TO: MAYOR AND TOWN COUNCIL FROM: LAUREL PREVETTI, TOWN MANAGER SUBJECT: APPROVE THE BAS IS OF DESIGN REPORT FROM WILSEY HAM ON THE ALMOND GROVE STREET REHABILITATION PHASE II PROJECT 411 -811 -0003 AND PROVIDE DIRECTION ON THE PROJECT BIDDING RECOMMENDATION : Approve B a sis of D esign report from Wilsey Ham on the Almond Grove Street Rehabilitation Phase II project 411 -811 -0003 and provide direction on the project bidding . BACKGROUND : The Almond Grove Street Rehabilitation project is intended to renew the streets and rehabilitate curb, gutter, and sidewalks consistent with Council direction in the Almond Grove and Broadway h istoric d istricts. The Council has discussed t he project over the course of nine meetings , beginning in 2012. Most recently, o n April 19, 2016, the Town Council authorized the Town Manager to negotiate and execute an agreement with Wilsey Ham for the design of the remaining eight Almond Grove streets . The design was to follow guidelines provided by Coun cil during the October 20, 2015 Council meeting. During the October meet ing, Council approved the plans and specifications for bidding Broadway and Bachman and provided the f ollowing design direction for all of the Almond Grove Streets:  Keep the existing curb line in the same location.  Include Americans with Disabilities Act (ADA) improvements where needed for compliance with ADA while saving as much sidewalk as possible.  Han dle trees per the Town’s tree ordinance, with an emphasis on trying to save trees.  Institute a five -year no -cut rule on the streets after re constructed including a specified replacement practice if streets are cut. PAGE 2 MAYOR AND TOWN COUNCIL SUBJECT: BASIS OF DESIGN REPORT FROM WILSEY HAM ON THE ALMOND GROVE STREET REHABILITATION PHASE II PROJECT 411 -811 -0003 AUGUST 23 , 2016 DISCUSSION : Basis of Design Report Wilsey Hamm has completed the design through the 35 percent design phase. This includes su rveying, soil investigation, utility locations , preliminary design , and design layouts. As part of this phase, Wilsey Hamm has provided a Basis of Design report tha t will be used to determine details of the next more in - depth design phase of the project by defining the scope, approach , and proposed design criteria . This report is included as Attachment 1 . The appendix, due to its size, is available for viewing on t he Town’s website at http://www.losgatosca.gov/2310/Almond -Grove -Phase -II . The Basis of Design report makes a number of recommendations regarding the design which includes the following:  Pavement S ection – T he pavement section design is approximately five to five and a half inches of concrete on top of cement treated subgrade and base rock . On Broadway and Bachman , the Town used five inches of concrete on top of base rock. Wilsey Ham is recommending the use of cement treated subgrade and base rock to minimize the off haul of subgrade and the import of base rock and to provide for greater efficien cy in construction while minimizing cost s . Cement treated subgrade is an estab lished process to mix cement with the existing soil (subgrade). The cement serves to harden the subgrade so that the appropriate compaction level can be obtained. Soil tests conducted by Wilsey Ham provided the basis for the engineering to validate this option.  Utilities – Wilsey Ham has collected record data and completed field investigations on the locations of existing utilities. These investigations have shown numerous shallow utilities. Design strategies will be incorporated into the project to wo rk around shallow utilities where feasible. The c onsultant will coordinate with the utility companies to identify utilities that may need to be relocated because of their depth or that need to be replaced due to age. The schedule for utility comp anies co mpleting this work may a ffect the order that the streets can be constructed .  Curb and Gutter and Driveway Approach – Similar to Broadway and Bachman, t o minimize roadway excavation, minimize conflicts with existing utilities , and conform to the new street pavement appropriately, the roadway elevation will be raised and new curb and gutter will be installed along with replacement of drivewa y approaches to match the new flow line elevation s .  Cost Estimate – Previously, only conceptual design work had been completed on the remainin g eight streets in the Almond Grove neighborhood. C osts extrapolated from the low bids on Broadway and Bachman were used to estimate the cost for the remaining streets. This cost was estimated to be approxim ately $12.6 million (construction cost only). Based on the design data collected to date o n the remaining streets, Wilsey Ham’s current preliminary construction cost PAGE 3 MAYOR AND TOWN COUNCIL SUBJECT: BASIS OF DESIGN REPORT FROM WILSEY HAM ON THE ALMOND GROVE STREET REHABILITATION PHASE II PROJECT 411 -811 -0003 AUGUST 23 , 2016 DISCUSSION (cont’d): estimate for the streets is $12.3 million. This is an estimate b ased on current pricing based on this phase of design. The estimate will continue to fluctuate through the design process. The actual project cost can be determined only through the competitive bidding process. Next Steps Staff is continuing to move forward with the design elements on the Almond Grove Phase II project. Addressed below are recommendations on various key design points for Council’s reference: Asphalt Areas within Phase II P roject L imits Council previously approved full length concrete reconstruction of eight Almond Grove s treets in the Phase II project, including Nicholson, Bean , and Bayview Avenues. Small sections of roadway on Nicholson, Bean , and Bayview are currently asphalt. These sections are as fol lows:  Bayview Avenue: from W. Main Street to Pennsylvania Avenue  Bean Avenue: from Massol Avenue to the west end  Nicholson Avenue: from Massol Avenue to Glen Ridge Avenue Staff is moving forward with Council direction to replace the entire street length s with concrete , including the above referenced asphalt sections . The cost to replace these sections of asphalt roadway within the concrete streets is approximately $450,000. These costs have been included in project budgeting and estimates , and funding h as already been identified in the Capital Improvement Program budget . Project Bidding Past discussion s with Council ha ve included alternative methods for bidding the Phase II project. Under consideration are two alternatives . The first alternative is to bid all eight streets at the same time and the second alternative is to bid two streets per year. There a re pros and cons for each alternative which are listed below. Pros of bidding all streets at one ti me :  Larger quantity may result in lower unit co sts . Cons of bidding all streets at one time:  Contractors have limited capacity to obtain bonds for projects. Larger companies will have a higher bonding capacity and thus will be able to bid on a combined project . Mid -size companies may not have that capacity and therefore would be unable to bid, thereby limiting competition. Small companies will likely not participate in either bidding method due to the size and complexity of the work. PAGE 4 MAYOR AND TOWN COUNCIL SUBJECT: BASIS OF DESIGN REPORT FROM WILSEY HAM ON THE ALMOND GROVE STREET REHABILITATION PHASE II PROJECT 411 -811 -0003 AUGUST 23 , 2016 DISCUSSION (cont’d):  The bidding c ontractor s will need to factor in labor and material increases for future years, and may do so at a level to minimize their risk in escalation of these prices over time . Pros of bidding 2 streets per year:  More c ontractors will be able to meet the bonding requirements, allowing more to bid the project and possibly allowing for lower bids.  Contractor will have actual costs for labor and material when bidding the project. Cons of bidding 2 streets per year:  Lower quantities may cause higher unit costs A lth ough the large r quantity from bidding all eight streets at one time has the potential of result ing in lower unit bid prices, staff believes that the higher bonding requirements and the uncertainty associated with future labor and material costs make biddin g two streets at a time the best option . Based on the current progression of the roadway reconstruction for Broadway and Bachman, it is unlikely a c ontractor could complete more than two streets a year before the winter storm season begins. If a c ontract or did propose providing additional crews to construct more than two streets per construction season , the disruption to t he Almond Grove residents could quickly increase to an unacceptable level and staff would be unable to continue to provide effective co mmunity outreach for all impacted residents. For these reasons, staff is recommending bidding the project two streets at a time. Staff will provide Council with the proposed schedule for construction once discussions regarding possible utility relocati ons and/or replacements have been concluded with the utility companies , as these may impact the schedule . Fiber Optic Cable Staff previously provided conduit for future use of pass -through fiber optic cable on both Broadway and Bachman, providi ng a n east -west connection for any future pass -through fiber optic cable lines and helping to prevent possible cuts to the new concrete streets. Staff additionally noted the necessity to install a north -south connection through the Almond Grove neighborhood fo r future pass -though fiber optic cable to prevent street cuts from occurring . Recently , the Zayo Group, a telecommunications company, requested an encroachment permit to underground fiber optic conduit and cable from Highway 9 down Massol, Bean , and Bay v iew to Main Street. Staff recognized this as an opportunity to work with Zayo Group to secure an additional empty conduit in the Almond Grove neighborhood and obtain the needed north -south connection for future pass -through conduit in the Almond Grove, th ereby saving the Town the expense for this conduit. Fiber PAGE 5 MAYOR AND TOWN COUNCIL SUBJECT: BASIS OF DESIGN REPORT FROM WILSEY HAM ON THE ALMOND GROVE STREET REHABILITATION PHASE II PROJECT 411 -811 -0003 AUGUST 23 , 2016 DISCUSSION (cont’d): optic companies are not required to provide empty conduits for jurisdictional use ; however, staff was able to work with the Zayo Group to obtain an empty conduit for futur e Town use. As the Town now has both east -west and north -south conduits in the Almond Grove for future pass - though fiber optic cable, no further placement of empty conduit is recommended for the Almond Grove streets. Schedule The following schedule is anticipated for the Almond Grove Phase II project: Design Completion January 2017 Council Approval of Plans, Specifications, and Engineering and Authorize TM Award to Low Bidder February 2017 Award of Bid April 2017 Construction Start (2 Streets) May 2017 Construction End December 2017 CONCLUSION : The Council’s approval of the Basis of Design r eport would provide documented direction to the consultant at a relatively early stage on the impo rtant elements of the design so that they can move forward with a clear understanding of the project objectives and design elements through project delivery. Staff recommends that the Council a pprove the basis of design report from Wilsey Ham on the Almond Grove Street Rehabilitation Phase II project 411 -811 -0003. ALTERNATIVES: Alternatively, t he Council could modify the B asis of D esign report to incorporate other elements or direction . COORDINATION: This report has been coordinated with the Finance Department.

Basis of Design Report 3130 La Selva Street, Suite 100  San Mateo, CA 94403  650/349-2151  Fax 650/345-4921 MEMORANDUM Date:August 19, 2016 From:Amy Dunning, P.E. To:Ryan Do Town of Los Gatos Parks & Public Works Department 41 Miles Avenue Los Gatos, CA 95030 Job No.:1012-001 Re:Almond Grove Street Reconstruction Phase 2 Project – Basis of Design Report Copies to: Wilsey Ham has prepared this Basis of Design Report that includes pavement design and cost estimates for the Almond Grove Street Reconstruction Phase 2 Project (AGP2). The Phase 2 Project includes the following street segments: Almendra Avenue from N. Santa Cruz Avenue to Massol Avenue, Bayview Avenue from W. Main Street to Bean Avenue, Bean Avenue from N. Santa Cruz Avenue to the north end, Glen Ridge Avenue from Hernandez Avenue to Bachman Avenue, Massol Avenue from Bean Avenue to Los Gatos-Saratoga Road, Nicholson Avenue from N. Santa Cruz Avenue to Glen Ridge Avenue Tait Avenue from W. Main Street to Los Gatos-Saratoga Road, Wilder Avenue from Bean Avenue to Bachman Avenue. The goals of the BOD report are to define the scope of the project, explain the approach used in our design, identify the proposed design criteria and get concurrence from the Town on our design approach. At this time, it is imperative that we reach a consensus with the Town on the scope and approach so that we can progress the design in the right direction and meet the project schedule. Geotechnical Investigation & Pavement Design One of the first tasks for the project was to perform a geotechnical field investigation. Thirteen locations throughout the 7 streets were selected for core sampling. Each core sample was used to determine the existing pavement section and the characteristics of the subsurface materials. All streets are paved with Portland Cement Concrete (PCC) ranging in thickness from 5 inches to 6.5 inches. Base material was not encountered in any of the PCC core samples. Laboratory testing of the subgrade materials was performed in order to determine the engineering properties of the subgrade material. This information was then used to design the Jointed Plain Concrete Pavement (JPCP) pavement section. The JPCP section has been designed for a 40 to 50-year design life utilizing the traffic data and TI (6.5) provided by the Town. The pavement section consists of 5 to 5.5-inches of JPCP and a 6-inch cement treated subgrade section. The cement treated subgrade requires a period of approximately 2-4 days for curing, prior to installation of the concrete slab. However, the cement treated subgrade can withstand the loading of residential traffic by the end of cement treatment each work day. Due to variations in subgrade material, each street has a site specific JPCP thickness for each alternative. Street specific sections are provided in Table 6 of the geotechnical report. A copy of the geotechnical report is provided in A ttachment 1 and includes a thorough summary of the field investigation and pavement design. Additional Field Investigation Wilsey Ham has performed an investigation into existing utilities that includes collection of record utility maps, utility location and marking of all existing utilities using Ground Penetrating Radar (GPR) and a potholing program. Underground utilities include gas, water, sanitary and storm. For the most part, electric and communications facilities are overhead. GPR was used to identify the horizontal locations of all underground utilities including mains and services. The GPR data also included approximate depths. Existing utility depths were then spot-checked through the potholing program. The information obtained indicates that there are a significant amount of shallow utility services and some shallow utility mains within the project area. Design strategies to minimize the impact on these utilities will be incorporated into the project, to the extent feasible. However, early coordination with utility companies will be essential to establish a strategy for lowering existing utilities, as needed. Wilsey Ham has also performed a topographic survey, collecting field information such as utility paint marks, street cross sections, surface utilities, existing trees and detail of existing curb ramps. Lastly, Wilsey Ham design engineers conducted a detailed site walk to observe site conditions, verify project base mapping, identify any additional site constraints and determine locations of sidewalk replacement. Proposed Improvement Design The primary goal of this basis of design report is to define the scope of improvements, prior to moving into detailed design and grading. Our proposed approach to the design is summarized below: 1.Remove and replace existing concrete pavement within the streets. 2.Remove and replace existing curbs on each side of the street. a.In order to reduce roadway excavation depths and minimize potential for conflicts with existing shallow utilities, roadway elevations will be raised and new 6-inch curbs will be installed. Existing curb heights vary from 6 to 8-inches in height. Top of curb elevations will generally be maintained and flowlines will be adjusted along the streets and at conforms. All through curb drains will be reconstructed to new flow line elevations. b.Due to the Town’s desire to maintain existing roadway widths, curb alignments have been drawn to match existing curb alignments. This may result in non- parallel curb alignment with angle points in certain locations. 3.Replace all driveways between the curb and back of walk. Driveway elevations will be adjusted to new flowline elevations and they will provide an accessible path of travel at the sidewalk crossing. Existing driveway widths will be maintained. Driveway conforms will be designed with the grading design. 4.Replace existing sidewalks that are in poor condition or sidewalks that are not ADA compliant. These areas were determined in the field by performing a visual inspection and smart level survey for the entire project. Proposed sidewalk widths will match the existing sidewalk widths, all of which are 5 feet or wider. 5.Replace non-compliant curb ramps. The curb ramp configuration will be designed with the grading. Proposed curb ramp configurations will be consistent throughout the project to the greatest extent possible. 6.Remove existing hardscape improvements between the back of curb and edge of sidewalk, as needed. Establish continuous planter strips in these areas, interrupted only by driveways. 7.Remove existing trees identified by the arborist for removal in compliance with the Town’s tree removal policy. New tree installations will be proposed upon verification by the Town of proposed planter strips. 8.Replace existing water meter boxes and water and gas valve boxes within the project, as needed. 9.If sidewalk repairs are required in areas identified by the Town Master Plan for the installation of Villa Hermosa sidewalks, the sidewalk in between the repair areas will also be replaced in order to avoid dissimilar types of sidewalks. The project will not install Villa Hermosa sidewalk if repairs are not required in those areas. Cost Estimates Cost estimates have been prepared for each of the streets and are provided in Appendix G . These estimates are based on the recent bid results from the Almond Grove Phase 1 project. Estimates include quantities for demolition, import, and new improvements. It has been assumed that utility owner’s will be responsible for utility relocations, so the engineer’s estimates do not include costs for those. Wilsey Ham has witnessed rising construction costs in recent times. It is anticipated that they will continue to rise through bidding of the Phase 2 project in January, 2017. Our Engineer’s Estimates will update unit prices if more recent bid results become available. A summary of the cost estimates is provided below in Table 1. Cost Estimate Almendra Avenue $1,097,700 Bayview Avenue $736,800 Bean Avenue $1,038,300 Glen Ridge Avenue $1,266,900 Massol Avenue $2,619,000 Nicholson Avenue $1,010,000 Wilder Avenue $1,178,400 Tait Avenue $3,325,000 TOTAL $12,272,100 Table 1 – Cost Estimates A TTACHMENT 1 – GEOTECH REPORT i | Page August 10, 2016 Project No.: 160397.5 Wilsey Ham 3130 La Selva Street, Suite 100 San Mateo, CA 94403 Attn: Ms. Amy Dunning, P.E.

PROJECT DESCRIPTION The town of Los Gatos (the Town) intends to reconstruct several residential streets located within the historic Almond Grove District. Twining was been authorized by Wilsey Ham to perform an engineering evaluation of the existing pavement within the project limits to develop geotechnical pavement design recommendation. We understand the Town is interested in obtaining recommendation for Jointed Plain Concrete Pavement (JPCP) with a 40 year design life. The streets evaluat ed by Twining included the following:  Bayview Avenue, from West Main St reet to Los Gatos-Saratoga Road;  Glen Ridge Avenue, from Hernandez Avenue to Bachman Avenue;  Massol Avenue, from Bean Avenue to Los Gatos-Saratoga Road;  Wilder Avenue, from Bean Avenue to Bachman Avenue;  Bean Avenue, from North Santa Cruz Avenue to north end of Bean Avenue;  Almendra Avenue, from Massol Avenue to North Santa Cruz Avenue; and  Nicholson Avenue, from North S anta Cruz Avenue to Glen Ridge Avenue. A site plan showing the project limits is provided in Appendix A. It is our understanding that Tait Avenue was already designed to the 70 percent level of comple teness, and therefore was no t evaluated as part of our scope of work. 2. PREVIOUS INVESTIGATION A previous investigation and pavement design was conducted by NCE in Marc h 5, 2015 for the Phase 1 portion of the reconstruction. The Phase 1 scope, however, was limited to Broadway, Tait Avenue and Bachman Avenue. NCE’s investigation included P CC pavement coring, Falling Weight Deflectometer (FWD) Testing, Dynamic Cone Penetro meter (DCP) testing, and laborator y R-Value testing of subgrade samples. Subgrade samples were obtained from thei r field exploration, whic h consisted of sands and clayey sands. The moisture contents of the subgrade varied from 8 to 13 percent. The results were analyzed and data were inputted in to StreetPave to provide structural pavement sections. Based on their investigation, the followi ng structural pavements sect ions were recommended:  Minimum slab thickness of 5.0 inches; over  5.0 inches of crushed stone base, and tied gutters. 3. SCOPE OF SERVICES The purpose of our investigation was to document th e existing pavement surfac e condition and structural sections and provide recommendations for reconstructi on. In order to accomplish the objectives of this investigation, the following tasks were completed:  Conducted a visual assessment of the ex isting condition of the pavement surface;  Performed coring and logging of the pavement struct ural sections at selected locations within the project limits;  Obtained subsurface soil sampling for further laboratory testing;  Conducted engineering analyses to provide pavement design recommendations; and  Prepared the report presenting a summary of our findings, conclusions, and recommendations. 2 | Page 4. FIELD INVESTIGATION 4.1. Pavement Surface Condition Assessment A visual pavement surface condition assessment was performed on May 26, 2016 in order to observe and document the existing pavement su rface distresses. Based on our visual assessment, the following distresses were observed with in the project limits. Divided Slab  Low to high severity depending on location.  Slabs are divided by cracks (longitudinal, transve rse, and diagonal) into four or more pieces due to overloading, or inadequate support, or both.  Cracks vary in widths from 1/8 inch to as much as 3 inches. Large Patching (more than 5.5 ft 2 ) and Utility Cuts  Low to medium severity.  The majority of the patches in the area are functi oning well, with little or no deterioration. Some utility patches, however, are moderately deteriorated, or modera te spalling can be seen around the edges. Corner Spalling  Medium to high severity.  Depth of spalls varied from 1 inch to greater than 2 inches. Joint Spalling  Medium to high severity.  Width of spall varies from 4 inches to as much as 9 inches.  Joint spalling due to excessive stre sses at the joints caused by tra ffic loading or by infiltration of incompressible materials.  Other causes include weak concrete at the join t caused by overworking, and water accumulation in the joint. Selected photos of the distresses are provided in Appendix B. 4.2. Field Exploration The field exploration was conducted on June 10, 2016 and consisted of pavement coring and sampling of the underlying soil materials. The existing pavement sections were evaluated by coring using a Transwest Asphalt CoreRig (Model: T-1000 coring system) with a 6-inch diameter coring bit. A total of thirteen pavement cores were obtained at pre-selected locations within the project limits. The underlying pavement materials were explored by soil boring using a hand-auger to the maximum exploratory depth of three feet below the existing pavement surface. A site plan showing the locations of the cores is provided in Appendix A. A summary of information obtained from the field exploration, such as pavement type, thickn ess and the type of subsurface materials encountered at each coring location are presented in Table 1. All streets within the project limit s are paved with Portland Cement Co ncrete (PCC). Based on the coring results at selected locations, the thickness of the PCC varies between from 5 to 6.5 inches within the 3 | Page project limits. The exception is at coring location C-12 where a 2 inch thick layer of asphalt concrete was encountered on the west end of Bean Avenue. It is noted that C-12 wa s cored on an asphalt driveway that leads to residences on the north-west end of Bean Avenue. The subgrade soils beneath the pav ement generally consisted of clay ey sands or clayey sands with gravel; with the exception of coring location C-12. The clayey sands were described as brown in color, well graded, moist and containing occasional rock fr agments with angular particle sizes ranging from 1 to 3 inches in the largest dimension. At coring lo cation C-12, however, the underlying pavement soils consisted of a 5.5 inch thick layer of aggregate ba se (poorly graded sandy grav el) over brown, clayey sand. The subgrade soils were found to be relatively consis tent in composition at all coring locations.

Laboratory Testing Results Geotechnical laboratory tests were performed on selected soil samples obtained from the field investigation in order to aid in the soil classifica tion and to evaluate the engineering properties of the subgrade soils. The selection of soil samples for te sting highly depends on the variability of the so ils that is encountered during the subsurface evaluation. To obtain the most representative samples, at each core location, the subgrade soil is visually investigated and classified by the onsite Engineer. If t he soil type is significantly 4 | Page different from the other samples collected, a new soil sample will be collected and potentially selected for further laboratory testing and analysis. If the subgrade soil is recognized as the similar in composition as previously collected sample, no sampling or mini mum soil sampling will be obtained. The type and quantity of soil samples selected for testing were based on judgment and are typical for a project of this scope and magnitude. If the subgrade soils exposed during construction are significantly different t hat those encountered during the field investigation, additional samples should be collected for further testing and analysis. The laboratory testing progra m consisted of the following:  Water (moisture) content;  Liquid limit, plastic limit and plasticity index of soils;  Particle-size analyses of soils by washing;  Maximum dry density and optimum moisture content;  Corrosivity series tests (soluble sulfates, soluble chlorides, pH and electrical resistivity) on soils;  Resistance R-Value and expansion pressure of compacted soils;  Expansive Index of soils; and,  Analytical testing.

Particle Size Distribution  Particle size analysis indicate the subgrade soil s are coarse-grained, with the following particle size distribution: o 12 to 23% gravel. o 40 to 54% sand. o 25 to 43% fines. Liquid Limit, Plastic Limit and Plasticity Index  Atterberg Limit testing on the materials passing t he No. 40 sieve indicates that the material is a low plastic clay. Expansion Index  Four selected samples were analyzed by Wallace Kuhl and Associates for the expansion index of soils.  The Expansion Index varied from 4 to 38, indicating a very low to low potential for expansion. Soil Corrosivity  Five soils samples were analyzed by BSK Associates for the following: o soluble chlorides (California Test Method 422) o soluble sulfates (California Test Method 417) o pH (California Test Method 643) o electrical resistivity (California Test Method 643)  Soluble chlorides varied from not detectable (ND) to 32 ppm, which indicates a low potential for corrosion  Soluble sulfates varied from not detectable (ND) to 120 ppm (0.012%), which indicates a low degree of exposure to sulfate attack on concrete structures  pH varied from 7.4 to 8.3  Minimum electrical resistivity varied from 2,490 to 9,710 ohm-cm, which indicates a low to moderate potential for corrosion. Resistance Value (R-Value) Bulk samples were selected for R-Value testing and the results ranged in value from 6 to 34, which indicates typical values for soils ranging fr om clays, sandy clay s and clayey silts. Analytical Testing Nine soil samples from various depths were analyzed by SunStar Laboratories, Inc., a California State certified laboratory located in Lake Forest, Califor nia. All of the soil samples were analyzed for the following potential contaminants: 6 | Page  Extractable petroleum hydrocarbons in the gaso line range organics (GRO), diesel range organics (DRO) and motor oil range organics (EPA Method 8015C)  California Code of Regulations (CCR) Title 22/California Assessment Manual (CAM) Metals (EPA Method 6010 and 7010 Series)  Organochlorine Pestic ides (EPA Method 8081)  Polychlorinated Bipheny ls (EPA Method 8082)  Volatile organic compounds (VOCs) (EPA Method 8260)  Polycyclic Aromatic Hydrocarbon (PAH). The results of analytical testing of the contaminants that were detectable or present in the subgrade soils are summarized in Table 3. The details of the results are provided in Appendix D.

The California Code of Regulations (CCR), Title 22, Section 66261.24 establishes Total Threshold Limit Concentration (TTLC) values. These values when exceeded would pose a hazard and affect the water quality of the State if not properly managed. The analytical testing results in Table 3 were compared to the CCR regulatory limits, and the following were noted:  Barium varied from 110 to 170 mg/kg, which is less than the 10,000 mg/Kg TTLC value;  Chromium varied from 44 to 70 mg/kg, which is less than the 500 mg/Kg TTLC value;  Cobalt varied from 13 to 19 mg/kg, whic h is less than the 8,000 mg/Kg TTLC value;  Copper varied from 10 to 23 mg/kg, whic h is less than the 2,500 mg/Kg TTLC value;  Lead varied from not-detectable to 73 mg/kg, which is less than the 350 mg/Kg TTLC value;  Nickel varied from 33 to 68 mg/kg, which is less than the 2,000 mg/Kg TTLC value;  Vanadium varied from 42 to 59 mg/kg, which is less than the 2,400 mg/Kg TTLC value;  Zinc varied from 54 to 78 mg/kg, which is less than the 5,000 mg/Kg TTLC value; and,  Mercury varied from not-detectable to 0.69 mg/kg, wh ich is less than the 20 mg/Kg TTLC value. The remaining contaminants analyzed were not-detected. In summary, the soils sampled from the site are considered non-hazardous based on limited analytical testing, and may be suitable for disposal at a Class II or Class III land fill. Howeve r, the results of analytic al testing should be provided to the land fill operators for review and acceptance prior to hauling offsite. 7 | Page 5. ENGINEERING ANALYSES In accordance with the City’s request, we have performed engineering analyses for JCPC pavement design. The computer program "StreetPave 12", designed and developed by American Concrete Pavement Association (ACPA), was used as the bas is for design of the RC C pavement section in addition to the latest version of Caltr ans Highway Design Manual (HDM). 5.1. Design Parameters Our analysis was perf ormed for each street section separatel y. The R-value of the subgrade, obtained from laboratory tests, and the traffic information, provided by the Town, are used in the design of pavement structural sections. The R-value and traffic information used for each section are presented in Table 4. Table 4 – Design Parameters for Each Section Section R-Value Design AADT (Total of Both Direction) Truck Percentage *** Traffic Growth Factor *** Glen Ridge Avenue 24 1,500 2% 2% Massol Avenue 6 2,300 2% 2% Bayview Avenue 6 * 1,500 ** 2% 2% Wilder Avenue 14 1,500 ** 2% 2% Nicholson Avenue 9 1,500 ** 2% 2% Almendra Avenue 13 1,500 ** 2% 2% Bean Avenue 6* 1,500 ** 2% 2% * R-Value obtained from Core# 4 which is the closet core to this section ** AADT was not provided for these sections by the Town and therefore the AADT for Glen Ridge Avenue was used. ** For the “Truck Percentage” and the “Traffic Growth Factor” the values recommended by Streetpave was used in our design For all sections, the “Residential” traffic spectrum wa s selected in Streetpave software. This spectrum has a good estimation of the typical traffic counts of each axle load in residential areas. Upon request of the Town, Twining can provide designs wi th different traffic information for each section. 6. CONCLUSIONS AND RECOMMENDATIONS Two different design options were considered for th is project; JPCP over aggr egate base and JPCP over cement stabilized subgrade soil. 6.1. JPCP over Aggregate Base In this option we have considered constructing JP CP over 6 inches of cr ushed aggregate base. The summary of the recommended design for each road se ction is presented in Table 5. Appendix E, presents the detail of the recommended designs of JPCP over aggregate base for each section. 8 | Page Table 5 – Summary of Pavement Design (JPCP over Aggregate Base) Section JPCP Thickness (in) Aggregate Base Thickness (in) Maximum Joint Spacing (ft) Glen Ridge Avenue 5.5 6.0 10.5 Massol Avenue 6.0 6.0 12.0 Bayview Avenue 6.0 6.0 12.0 Wilder Avenue 6.0 6.0 12.0 Nicholson Avenue 6.0 6.0 12.0 Almendra Avenue 6.0 6.0 12.0 Bean Avenue 6.0 6.0 12.0 Tait Avenue 1 5.0 5.0 10.0 Note: 1 Pavement structural sections for Ta it Avenue was provided by NCE, 2015 For construction of this option we recommend to follow the steps below:  Remove the existing pavement and excavate the subgrade soil to the bottom of the new aggregate base layer;  Scarify the exposed bottom of the excavation to a depth of at least 8 inches; moisture conditioned to approximately 2 percent above the optimum mo isture content, and compact to at least 90 percent of the maximum dry density as determ ined from the latest version of ASTM D 1557;  The aggregate base course layer should then be placed and compacted to a minimum of 95 percent of the maximum dry density as evaluat ed by the latest version of ASTM D 1557;  Construct the required thickness of JPCP over the compacted base, according to 2015 Standard Specification for Public Work s Construction (Greenbook); The maximum size of the joint spacing depends on the thickness of the JPCP and varies for each road section. The ratio of longer side slab length to the shorter side slab length should be kept less than about 1.2. 6.2. JPCP over Cement Stabilized Subgrade Soil In this option we have considered constructing JPCP over 6 inches of ce ment stabilize su bgrade soil. The summary of the recommended designs for each secti on is presented in Table 6. Appendix F, presents the details of the design of JPCP over cement stabilized subgrade soil for each section.

The recommended maximum joint spacing fo r each road section is presented in Appendix F. The ratio of longer side slab length to the shorter side slab length should be kept less than about 1.2 6.3. Recommended Remedial Measures for Soft Subgrade For the option 5.1, if soft subgrade soils are encoun tered during construction, remedial measures would be required to stabilize the subgrade prior to placement of base surface layer of the pavement. The intent of these remediation methods is to achieve a non-yielding subgrade when subjected to relatively heavy, rubber-tired construction equipment loading such as a loaded water truck or loader with full bucket. The remediated areas should be proof-rolled with this type of equipment after remediation to confirm that the subgrade is unyielding. The measures to stabilize the subgrade can consist of either of the following methods:  Remove unstable soils to a depth of approximate ly 1 to 2 feet below the bottom of the new aggregate base course, placement of geogrid materi al (Tensar TX 130 or equivalent) at the bottom of the excavation, and place of aggregat e base to replace the unstable soil. Shallow utilities at this depth of excavation may be en countered and must be ca refully identified and marked if this option is selected.  Cement treatment of the upper approximately 10 inches of soil can be performed in unstable areas to create a firm, unyielding working platform for aggregate base placement and compaction. Based on the subgrade soil types encountered in our exploration, we recommend using appropriate cement content to obtain cement treated mix with minimum of 400 psi unconfined compressive strength. The recommended depths of remediation (i.e., approximatel y 10 inches for cement treatment or up to 1 to 2 feet for the geogrid/aggregate base replacement) could be greater, or less, depending on the conditions encountered. Any areas that require remediation should be observed by the geotechnical engineer to confirm the effectiveness of the re commendations provided herein. 10 | Page 7.

If Field Reagent Blanks were not submitted with the samples, this method requirement has not been performed. •Samples collected by BSK Analytical Laboratories were collected in accordance with the BSK Sampling and Collection Standard Operating Procedures. •J-value is equivalent to DNQ (Detected, not quantified) which is a trace value. A trace value is an analyte detected between the MD L and the laboratory reporting limit. This result is of an unknown data quality and is only qualitative (estimated). Baseline noise, calibration curve extrapolation below the lowest calibrator, method blank detections, and integration artifacts can all produce apparent DNQ values, which contribute to the un-reliability of these values. •(1) - Residual chlorine and pH analysis have a 15 minute holding time for both drinking and waste water samples as defined by the E PA and 40 CFR 136. W aste water and ground water (monitoring well) samples must be field filtered to meet the 15 minute holding time for dissolved metals. •Summations of analytes (i.e. T otal T rihalomethanes ) may appear to add individual amounts incorrectly, due to rounding of analyte values occurring before or after the total value is calculated, as well as rounding of the total value. •R L Multiplier is the factor used to adjust the reporting limit (RL) due to variations in sample preparation procedures and dilutions required for matrix interferences. •Due to the subjective nature of the Threshold Odor Method , all characterizations of the detected odor are the opinion of the panel of analysts. The characterizations can be found in Standard Methods 2170B Figure 2170:1. •The MCLs provided in this report (if applicable) represent the primary MCLs for that analyte.
