Item 5d. Authorization to Advertise Sierra Way Sewer Replacement Project (Spec. 2000539)
Item 5d Department: Public Works Cost Center: 6102 For Agenda of: 9/3/2024 Placement: Consent Estimated Time: N/A FROM: Matt Horn, Public Works Director Prepared By: Hai Nguyen, Senior Civil Engineer SUBJECT: AUTHORIZATION TO ADVERTISE SIERRA WAY SEWER REPLACEMENT, SPECIFICATION NO. 2000539 RECOMMENDATION 1. Approve the project plans and specifications for Sierra Way Sewer Replacement, Specification Number 2000539; and 2. Authorize staff to advertise for bids; and 3. Authorize the City Manager to award the Construction Contract pursuant to Section 3.24.190 of the Municipal Code, if the lowest responsible bid is within the publicly disclosed funding amount of $3,500,000; and 4. Authorize the City Engineer to approve Contract Change Orders up to the available project budget and any amended budget subsequently approved by the City Manager up to $200,000. POLICY CONTEXT The City Council approved the Wastewater Collection System Infrastructure Renewal Strategy in January 2016. The plan identified a strategy for prioritizing pipeline replacement in the wastewater collection system to serve existing customers and future development in the City. On May 17, 2022, Council approved a Purchasing Policy Update to the Financial Management Manual that requires Council approval for Public Projects that cost over $200,000. DISCUSSION Background Replacement and rehabilitation of wastewater collection (sewer) pipes is part of an ongoing program to maintain aging and deteriorating infrastructure. This program has several objectives: 1) ensure reliable removal of wastewater; 2) reduce the need for emergency repairs; 3) reduce the need for preventative maintenance; and 4) ensure uninterrupted wastewater flow without health or environmental hazard s from wastewater leakage. This project will accomplish these objectives for a portion of the City’s wastewater collection system. Page 37 of 229 Item 5d The Project The project plans (Attachment A) and specifications (Attachment B) propose to replace 4,252 linear feet of sewer main in the capacity constrained areas located on Sierra Way, Ella Street, Ruth Street, George Street and Henry Street. The existing sewer pipes planned for replacement work have been video inspected and confirmed to have reached the end of their useful life. This high priority project has been a coordination effort over the past three years to increase capacity reliability of sewer services to the community hospital (French Hospital). The project plans and specifications include an additive alternate bid to install 350 linear feet of sewer main by open trenching along Bishop Street (Additive Alternative A). The installation of the sewer main as part of the additive alternate along Bishop Street and east of Johnson Avenue will provide sewer services to the Welcome Home Village project that is planned to be constructed on San Luis Obispo County -owned property on the corner of Johnson Avenue and Bishop Street. This additive alternate may be eligible for future grant opportunities, which are currently being investigated by the County of San Luis Obispo, which is the lead agency for the Welcome Home Village project. The strategy is to award the Base Bid and Additive Alternative A if the lowest responsible bid is within the publicly disclosed funding amount of $3,500,000. Future cost recovery from the County will be determined once the cost of items of work for Additive Alternative A is known. Previous Council or Advisory Body Action This Project was identified in the 2021-23 Financial Plan that was approved by Council with a budget of $1,850,000. Council also adopted the FY 2024-25 Supplement Budget and approved an additional $2,200,000 for the project on June 4, 2024. Public Engagement Public engagement was conducted during the initial identification of this Project to be included in the 2021-23 Financial Plan. In addition, public comment was open at the Council Meeting when the 24-25 Supplemental Budget was approved. CONCURRENCE This project has the concurrence of the Utilities Department. ENVIRONMENTAL REVIEW The project is categorically exempt from environmental review under Section 15303 (New Construction or Conversion of Small Structures) and 15304 (Minor Alterations of Land) because the project consists of the replacement and extension of existing sewer mains, including trenching, backfilling, and restoration of the existing streets. No tree removal is proposed. A Notice of Exemption will be filed through the Community Development Department. Page 38 of 229 Item 5d FISCAL IMPACT Budgeted: Yes Budget Year: 2021-23 Funding Identified: Yes Fiscal Analysis: Funding Sources Total Budget Available Current Funding Request Remaining Balance Annual Ongoing Cost General Fund State Federal Fees Sewer Fund: $4,006,335 $4,006,335 $0 N/A Total $4,006,335 $4,006,335 $0 N/A Sierra Way Sewer Replacement (2000539) Base Bid Estimate $3,207,000 Add Alt A Estimate $293,000 Contingencies $500,000 Material Testing $6,000 Printing $335 Total Cost of Project $4,006,335 Total Available Funding $4,006,335 Remaining Balance $0 The project is structured with a Base Bid and one Additive Alternative to maximize the scope of work within available funding. The strategy is to clearly define work and cost of the City’s base project and any additional cost associated with serving the We lcome Home Village project (Additive Alternative A), which will provide necessary information for grant applications or future cost recovery from the County. Funding for this project is available in the Project Account (2000539) which has a current balanc e $4,006,335 and will provide sufficient funding to support the project costs. Page 39 of 229 Item 5d ALTERNATIVES 1. Deny or defer approval to advertise. The City Council may choose to deny or defer the approval to advertise this project. Staff does not recommend this option, as the sewer mains serve the community hospital with sewer mains reaching the end of useful life and pose a high risk of catastrophic failure, requiring expensive repairs. 2. Remove Additive Alternative A from the project. The City Council may choose to approve the base bid for advertisement and remove Additive Alternative A from the project. Staff does not recommend this option as the proposed sewer main included with Additive Alternative A is necessary to provide sewer services for the Welcome Home Village.

Based on our discussions, we understand that the installation of the new sewer line will be by open trench installation. 2.0 SCOPE OF SERVICES The authorized scope of work included a general site reconnaissance, field exploration, geotechnical analysis of the data gathered, and preparation of this report. The analysis and subsequent recommendations were based on verbal information and a general project location plan provided by the client. This report and recommendations are intended to comply with the considerations of Sections 1803.1 through 1803.6, J104.3 and J104.4, as applicable, of the 2022 California Building Code (CBC) and common geotechnical engineering practice in this area under similar conditions at this time. The test procedures were accomplished in general conformance with the standards noted, as modified by common geotechnical engineering practice in this area under similar conditions at this time. Preliminary geotechnical engineering recommendations for trench backfill and observation and testing are presented to guide the development of project plans and specifications. As there may be geotechnical issues yet to be resolved, the geotechnical engineer should be retained to provide consultation as the design progresses. It may also be advantageous to retain the geotechnical engineer to review project plans as they near completion to assist in verifying that pertinent geotechnical issues have been addressed and to aid in conformance with the intent of this report. It is our intent that this report be used exclusively by the client to form the geotechnical basis of the design of the project and in the preparation of plans and specifications. Application beyond this intent is strictly at the user’s risk. This report does not address issues in the domain of contractors such as, but not limited to, site safety, loss of volume due to stripping of the site, shrinkage of soils during compaction, excavatability, dewatering, temporary slope angles, construction means and methods, etc. Analyses of aerial or site geology, or of the soil for corrosivity, radioisotopes, asbestos (either Page 85 of 229 City of San Luis Obispo, 2024 Sewer Upgrades April 5, 2024 San Luis Obispo, California 306551-001 2 2403-051.SER naturally occurring or in man-made products), lead or mold potential, hydrocarbons, or chemical properties is beyond the scope of this report. Any ancillary features such as flag or light poles, temporary access roads, non-structural fills, pipeline design, and retaining walls are not within our scope and are also not addressed. Design and/or suitability of LID features such as retention basins, bio swales, or other improvements are also beyond our scope. In the event that there are any changes in the nature, design, or location of improvements, or if any assumptions used in the preparation of this report prove to be incorrect, the conclusions and recommendations contained in this report shall not be considered valid unless the changes are reviewed and the conclusions of this report modified or verified by the geotechnical engineer in writing. The criteria presented in this report are considered preliminary until such time as any peer review or review by any jurisdiction has been completed, conditions have been observed by the geotechnical engineer in the field during construction, and the recommendations have been verified as appropriate, or modified by the geotechnical engineer in writing. 3.0 FIELD INVESTIGATION Fourteen exploratory borings were drilled at the site on February 28, 2024 through March 1, 2024 to depths of 10.0 feet and 16.0 feet below the ground surface (bgs). The borings were drilled with a truck-mounted Gtech GT8 drill rig equipped with a 6-inch outside diameter hollow stem auger and an automatic hammer for sampling. As the borings were advanced, soil samples were obtained using a 3-inch outside diameter lined barrel sampled (ASTM D 3550-17 with shoe similar to ASTM D 2937-17) and a standard penetrometer (ASTM D 1586). Bulk samples were also obtained from the auger cuttings. The approximate locations of the borings are shown on Figure 2 – Exploration Location Map in Appendix A. Soils encountered in the borings were categorized and logged in general accordance with the Unified Soil Classification System and ASTM D 2488-17. Logs of the borings are presented in Appendix A, along with a Boring Log Legend. In reviewing the boring logs and legend, the reader should recognize that the legend is intended as a guideline only, and there are a number of conditions that may influence the characteristics observed during drilling. These include, but are not limited to, the presence of cobbles or boulders, cementation, variations in soil moisture, presence of groundwater, and other factors. Consequently, the logger must exercise judgment in interpreting soil and bedrock characteristics, possibly resulting in soil descriptions that vary from the legend. It should be noted that the descriptions of bedrock must span a much wider range of density and strength characteristics than soil and are relative to other bedrock strata. Page 86 of 229 City of San Luis Obispo, 2024 Sewer Upgrades April 5, 2024 San Luis Obispo, California 306551-001 3 2403-051.SER For example, fractured and weathered bedrock may be described as “soft”, yet will be considerably harder than almost any type of soil. Conversely, a clay soil may be described as “hard”, however it will not be nearly as hard as “soft” bedrock. Selected samples were tested in our laboratory to determine the bulk density (ASTM D 2937-17, as modified for ring liners), moisture content (ASTM D 2216-10), maximum density and optimum moisture content (ASTM D 1557-12, modified), and grain size distribution (sieve per ASTM D 422- 63/07; D1140-17). The laboratory test results are presented in Appendix B. 4.0 GENERAL SUBSURFACE Throughout the exploration, the subsurface profiles varied by location. In Borings 1, 2, 6, and 9- 14, the subsurface profile consisted of alluvium overlying bedrock of the Franciscan Mélange Formation, which was encountered at depths ranging from 2.5 feet to 5.5 feet bgs with the exception of Boring 7 in which bedrock was encountered at 10 feet bgs. In Borings 3-5, 7, and 8, the profiles consisted of alluvium to the depth explored of 10 feet bgs. Residual soils were encountered in Borings 3 and 6 at a depth of 7.5 feet bgs. Alluvial soils consisted of sandy lean clay, sandy lean clay with gravel, lean clay, clayey gravel with sand, and poorly graded sand with gravel. The clay had a medium stiff to very stiff consistency, and the sand and gravel were medium dense to very dense . Residual soils consisted of medium dense clayey sand and soft sandy lean clay. Residual and alluvial soils were logged as moist to very moist. The Franciscan Mélange Formation bedrock was predominantly sandstone , although metavolcanic rock was encountered in Boring 6. Bedrock hardness varied from very soft to moderately hard, and the rock was moderately weathered or highly weathered. Subsurface groundwater was only encountered in Boring 14 at 3 feet bgs. Pavement sections of the existing roadways varied by location. Thickness of the asphaltic concrete ranged from 2 inches to 9.5 inches, and aggregate base material ranged from 2 inches to 10 inches. Fabric was periodically encountered in the sections. On Mill Street in Boring 5, a 5- inch thick concrete section was found to underly the asphaltic concrete. Please refer to the boring logs in Appendix A for a more complete description of the subsurface conditions encountered at the site. Page 87 of 229 City of San Luis Obispo, 2024 Sewer Upgrades April 5, 2024 San Luis Obispo, California 306551-001 4 2403-051.SER 5.0 CONCLUSIONS In our opinion, the site is suitable, from a geotechnical engineering standpoint, for the proposed project, provided the recommendations contained herein are implemented in the design and construction. The new sewer line is planned to be installed using open trench methods. From a geotechnical standpoint, the primary concern at the site is the potential for variable soil and bedrock conditions to impact the excavations. Based on the subsurface data, stiff sandy lean clay will be the predominant soil type encountered during excavation to overly the bedrock, although medium dense sands or soft clays may also be encountered , such as the residual soils encountered below Santa Rosa Street and Chorro Street, respectively . Gravels and cobbles may also be encountered such as the gravel found below Santa Rosa Street, Mill Street, and Chorro Street in Borings 3, 5, and 6, respectively. Bedrock hardness will vary considerably. For example during the subsurface exploration, very soft sandstone was encountered underlying Bishop Street while moderately hard sandstone was encountered below Sierra Way . For the purposes of preliminary planning and estimating of shoring or temporary excavation slopes, the alluvial and residual soils should be considered to be Type C soil, as defined by the California Division of Occupational Safety and Health (CALOSHA). Bedrock will also be encountered during excavation. Due to the variable conditions of hardness and weathering, rock materials should be considered to be Type B or C soil, as defined by CALOSHA, depending upon the jointing, fracturing, and dip. The contractor is responsible for all aspects of construction safety. Accordingly, the contractor’s “Competent Person” will need to perform his/her own evaluation of the soil types and appropriate sloping and/or shoring measures. 6.0 GEOTECHNICAL RECOMMENDATIONS These recommendations are applicable for the improvements as described in the “Introduction and Site Setting” Section of this report. If other improvements not previously mentioned are included, the geotechnical engineer should be contacted for revised recommendations. Unless otherwise noted, the following definitions are used in the recommendations presented below. Where terms are not defined, definitions commonly used in the construction industry are intended. • Moisture Conditioned: Soil moisture content adjusted to just above optimum moisture content prior to application of compactive effort. • Compacted / Recompacted: Soils placed in level lifts not exceeding 8 inches in loose thickness and compacted to a minimum of 90 percent of maximum dry density; however, 95 percent should be achieved in the upper 12 inches of subgrade in areas to be paved, Page 88 of 229 City of San Luis Obispo, 2024 Sewer Upgrades April 5, 2024 San Luis Obispo, California 306551-001 5 2403-051.SER and in all aggregate base. The standard tests used to establish maximum dry density and filed density should be ASTM D 1557-12 and ASTM D 6938-17, respectively, or other methods acceptable to the geotechnical engineer and jurisdiction. Trench Backfill 1. Trench backfill can be performed with the excavated soils recompacted to a minimum of 90 percent of maximum dry density; however, 95 percent should be achieved in the upper 12 inches of subgrade in areas to be paved, and in all aggregate base. Backfill should be moisture conditioned to optimum moisture content, or just above, prior to application of compactive effort. The backfill should be placed in level lifts not exceeding 8 inches in loose thickness and compacted to the minimums recommended above. 2. All materials used as fill should be cleaned of all debris and any rocks larger than 3 inches in the maximum dimension. When fill material includes rock, the rocks should be placed in a sufficient soil matric to ensure that voids caused by nesting of the rock will not occur and the fill can be properly compacted. 3. The recommendations of this section are minimums only and may be superseded by the requirements of the architect/engineer, the recommendations of pipe manufacturers or utility companies, or the requirements of the governing jurisdiction based upon soil corrosivity or other factors. Observation and Testing 1. It must be recognized that the recommendations contained in this report are based on a limited number of borings and rely on continuity of the subsurface conditions encountered. Therefore, the geotechnical engineer should be retained to provide consultation during the design phase, to review plans as they near completion, to interpret this report during construction, and to provide construction monitoring in the form of testing and observation. 2. At a minimum, the geotechnical engineer should be retained to provide: • Review of final plans • Professional observation during trench backfill • Oversight of soil special inspection during trench backfill Page 89 of 229 City of San Luis Obispo, 2024 Sewer Upgrades April 5, 2024 San Luis Obispo, California 306551-001 6 2403-051.SER 3. Backfill and compaction of excavations and trench should be considered to fall under Section 1705.6 “Soils” of the 2022 CBC. Special inspection of backfill should be provided as per Section 1705.6 and Table 1705.6 of the 2022 CBC. The special inspector should be under the direction of the geotechnical engineer. 4. It is our opinion that none of the grading construction is of a nature that should warrant continuous special inspection; periodic special inspection should suffice assuming the work is monitored by a County of San Luis Obispo Public Works Inspector. Subject to approval by the Building Official, the exception to continuous special inspection is described in Section 1704.2 of the 2022 CBC and should be specified by the architect/engineer and periodic special inspection of the following items should be provided by the special inspector: • Verify use of proper materials, densities and lift thicknesses during placement and compaction of compacted fill 5. A program of quality assurance should be developed prior to beginning construction. At a minimum, the program should include all geotechnical items shown on the testing and inspection schedule of the approved plans. It should also include any additional inspection items required by the engineer and/or the governing jurisdiction. 6. Locations and frequency of compaction tests should be per the recommendation of the geotechnical engineer at the time of construction. The recommended test location and frequency may be subject to modification by the geotechnical engineer, based upon soil and moisture conditions encountered, size and type of equipment used by the contractor, the general trend of the results of compaction tests, or other factors. 7. A preconstruction conference among the owner, the geotechnical engineer, the governing agency, the special inspector, the project inspector, the architect/engineer, and contractors is recommended to discuss planned construction procedures and quality control requirements. 8. The geotechnical engineer should be notified at least 48 hours prior to beginning construction operations.
