While the City has endeavored to accurately represent in the plans and specifications the physical conditions which may affect the cost of the proposed work, the City does not warrant the completeness or conditions affecting the cost of the work, which would have been disclosed by reasonable examination of the site.
Conclusions pertaining to any test, investigation, statement or estimate of fact incorporated in the plans and specifications shall be considered by the Contractor to be a recommendation only. The Contractor may request equal access to the underlying or background information to arrive at an independent opinion thereon, including the determination of how reliable might be any conclusion appearing r similar final or
accepted drawings or maps constructed on public or private property. Such information may be used for reference only. Actual locations and depths shall be determined by field investigations by the Contractor.

If an Excusable Delay and a Compensable Delay occur concurrently, the maximum extension of the contract time shall be the number of calendar days from the commencement of the first delay to the cessation of the delay which ends last. If an Inexcusable Delay occurs concurrently with either an Excusable Delay or a Compensable Delay, the maximum extension of the contract time shall be the number of calendar days, if any, by which the Excusable Delay or the Compensable Delay exceeds the Inexcusable Delay.

SECTION 10 - MEASUREMENT AND PAYMENT
10.01 Measurement of Quantities for Unit Price Work - Materials and items of work which are to be paid for on the basis of measurement shall be measured in accordance with the methods stipulated in the particular sections of the Contract Documents involved. Unless specifically stated otherwise in this contract, no extra measurement(s) according to local custom of any kind shall be allowed in measuring the work under this contract; only the length, area, solid contents, number, weight, or time in standard units, as the case may be, shall be considered as specified.
Unless otherwise specified, quantities of work shall be determined from measurements or dimensions in the horizontal planes. Stationing shall be along the street centerline, lengths of sanitary sewers, storm drains and water lines shall be measured as the horizontal distances from center to center of structures, rounded to the nearest foot, and lengths of all return radii and curb data shall be measured along the face of curb. Volumetric quantities shall be the product of the mean area of vertical or horizontal sections and the intervening horizontal or vertical dimensions. Measurements shall be in accordance with U.S. Standard Measures. A pound is an avoirdupois pound. A ton is two-thousand (2,000) pounds avoirdupois. The unit of liquid measure is the U.S. gallon.
When payment is to be made on the basis of weight, the weighing shall be done on certified platform scales or, when approved by the Engineer, on a completely automated weighing and recording system.
The Contractor shall submit to the
actual net weights. The City will accept the certificates as evidence of the weights delivered.

No compensation will be made to the Contractor, in any case, for loss of anticipated profits.
Increased or decreased scope involving a change order will be paid as stipulated in the change order.
The estimated value of work performed, for lump sum bids or lump sum bid items will be determined from the schedule of values, to be prepared by the Contractor and presented at the preconstruction meeting. Elements of work on the schedule of values shall be separated into groupings appropriate for the project. The Technical Specifications may be used as a guide for establishing these groupings. Move-in costs, bond and insurance costs, and submittal preparation costs can be included in the schedule of values under a separate mobilization line item. This line item shall not exceed five-percent (5%) value. Overhead and profit shall not be allowed as a line item, but shall be prorated over other items of work.
10.03 Bid Quantities - The quantities listed in the Bid Schedule for each bid item do not govern final payment. Payments to the Contractor will be made only for the actual quantities of contract items constructed in accordance with the plans and specifications. If upon completion of the construction, the actual quantities show either an increase or decrease from the quantities given in the bid schedule, the contract unit prices will still prevail.
Payment will not be made for materials wasted or disposed of in a manner not called for under the contract. This includes rejected material not unloaded from vehicles, material rejected after it has been placed and material placed outside of the plan lines. Unless otherwise provided, no payment will be made for materials delivered to the site but not incorporated in the work. Such quantities will not be included in the final pay quantities. No compensation will be allowed for the disposal of rejected or excess material.
When the estimated quantity for a specific portion of work is designated on the Bid Schedule as a specified portion of the work will be made, regardless of the actual quantity constructed, unless the dimensions of said portions of the work shown on the plans are revised by the Engineer.

No allowance will be made in the event that the quantities based upon computations do not equal the estimated quantities. Final pay quantities will be designated on the Bid Schedule with the letter (F) and shall only apply to the corresponding portions of work specifically designated on the plans. Any portion of work not designated as a final pay quantity will be measured and paid for as specified under other provisions of the Contract Documents.

GEOTECHNICAL RECOMMENDATIONS FOR LANDSLIDE REPAIR
Dear Mr. Cai:
As requested, we performed a geotechnical exploration to provide recommendations for repair of the landslide that occurred in winter 2023 adjacent to an approximately 20-foot-wide paved roadway with a 5-foot-wide sidewalk immediately south of 270 Dartmouth Avenue in San Carlos, California (Figure 1). This letter presents our findings, analysis, and recommendations for mitigation.
INTRODUCTION
The purpose of this letter, as described in our proposal dated June 27, 2023, is to provide geotechnical design recommendations in support of the landslide repair on Dartmouth Avenue.
We performed the following services.
Review of available historic aerial photographs, topographic maps, and geologic maps for the study area
Subsurface exploration consisting of three soil borings Topographic survey of the landslide area
Laboratory testing of select materials sampled during the field exploration Geotechnical data analyses
Letter preparation summarizing our conclusions and recommendations for the landslide repair During heavy rains in the past winter, we understand a slope failure occurred along the sidewalk shoulder of Dartmouth Avenue (Figure 1). Based on the condition observed during our initial visit, we recommended via email and oral communication that the area of the slope failure be backfilled with 6-inch riprap rock and covered with a tarp to temporarily stabilize the slope and minimize erosion. The riprap rock system appeared to have been performing adequately as of our latest site visit conducted on July 26, 2023.
An existing Cal Water utility line is located inside the road approximately 5 feet inward from the edge of the slope failure (parallel to the edge of slope).

GEOTECHNICAL RECOMMENDATIONS FOR LANDSLIDE REPAIR Page 2 We retained the services of a registered surveyor to complete a topographic survey of the landslide area on July 31, 2023. The survey information is included in Figure 1 (Site Plan). Based on the survey, the roadway surface and adjacent sidewalk is at approximately Elevation 425 feet (NAVD 88). The landslide was observed to be approximately 22½ feet in width at its widest point and 22½ feet in length (in the downslope direction). Topographic relief across the length of the landslide is up to 16 feet. An approximately 5- to 6-foot-high scarp is present at the head of the landslide. The scarp has partially undermined the sidewalk by approximately 2½ feet. Large cracks were observed in the undermined sidewalk.
FINDINGS
The site is located within the Coast Ranges geomorphic province, which is dominated by a series of northwest-trending, fault-bounded mountain ranges and intervening alleviated valleys.
Regional geologic mapping by Pampeyan et al (Geologic map of the Montara Mountain and San Mateo 7.5' quadrangles, 1994) indicates that the failure area is underlain at depth by Jurassic-age greywacke sandstone (fs) of the Franciscan Formation.
The site is located near active faults in the seismically active San Francisco Bay region. Numerous small earthquakes occur every year in the region, and large (greater than Moment Magnitude 7) earthquakes have been recorded and can be expected to occur in the future. The California Geologic Survey (CGS) defines an active fault as one that has had surface displacement within Holocene time (about the last 11,700 years) (CGS, 2018).
We determined the distance to faults in the area using The United States Geological Survey (USGS) Unified Hazard Tool, which uses specific fault segments for analysis. We disaggregated the hazard at the peak ground acceleration (PGA) for a 2,475-year return period. The resulting fault segments are listed in Table 1.

Notes: Based on USGS Unified Hazard Tool: Dynamic Conterminous U.S. 2014 (update) (v4.2.0). Numbers in brackets following the fault name refer to specific fault segments The fault segments listed above represent sources contributing at least 1 percent to the seismic hazard at the site at the PGA and for the given return period. Gridded or areal sources were not included. The 2015 Working Group on California Earthquake Probabilities evaluated the 30-year probability of a Moment Magnitude 6.7 or greater earthquake occurring on the known active fault systems in the Bay Area in the Third Uniform California Earthquake Rupture Forecast (UCERF3).
UCERF3 estimated an overall probability of 72 percent for the Bay Area as a whole, a probability of
14.3 percent for the Hayward fault.

GEOTECHNICAL RECOMMENDATIONS FOR LANDSLIDE REPAIR Page 3 We reviewed historic aerial photographs and topographic maps of the site dated 1896 through 2020, available on www.historicaerials.com. Review of the photographs indicates that a drainage swale was previously located at the failure area, as seen on the photographs dated back to 1930 and topographic maps dated back to 1896. Dense vegetation appears to be growing within the landslide area, with a dirt road bisecting the vegetation on either side. 270 Dartmouth Avenue and its adjacent road and sidewalk appear to have been constructed between 1960 and 1968 photograph, following the alignment of the dirt road. The site has remained relatively unchanged from the 1968 photograph and our exploration in 2023.
The field exploration for this study included advancing three exploratory borings on July 26, 2023, to a maximum depth of approximately 12½ feet below ground surface (bgs). The borings were permitted by San Mateo County Environmental Health. The borings were logged in the field and soil samples were collected using a 2-inch outside diameter (O.D.) Standard Penetration Test (SPT) split-spoon sampler. The penetration of the samplers into underlying materials was recorded as the number of blows needed to drive the SPT sampler 18 inches in 6-inch increments or the telescoping sampler 24 inches in 6-inch increments. The samplers were driven with a 140-pound hammer falling a distance of 30 inches employing a rope and cathead system.
The Site Plan shows the approximate locations of the exploratory borings. Borehole logs are attached in Appendix A. The boring logs record blow count results as the actual number of blows required for the last 1 foot of penetration; no conversion factors have been applied.
The surficial soil encountered generally consisted of hard sandy silt with gravel and medium dense silty sand with gravel extending to depths up to 5 to 8½ feet bgs. This layer appears to consist of the debris mass from the winter 2023 landslide. Below these deposits, we generally encountered highly weathered sandstone in borings 1-B1 and 1-B2. In boring 1-B3, we encountered a one-foot-thick lens of hard sandy lean clay directly underneath the sandy silt before reaching the highly weathered sandstone layer.
Groundwater was not encountered during our drilling operation.
We performed laboratory testing for moisture content and Atterberg Limits on select samples recovered from our borings. The laboratory test results are shown on the borelogs in Appendix A, with individual test results presented in Appendix B.
The 2022 California Building Code (CBC) utilizes seismic design criteria established in the -16). Based on the subsurface conditions encountered, we characterized the site as Site Class C. In Table 2, we provide the 2022 CBC seismic parameters.

We performed slope stability analysis through the landslide area considering the proposed mitigation as described in subsequent sections. The slope gradient and other topographic features used in our analyses were based on the results from the topographic survey on July 31, 2023.
Remedial measures are anticipated to include installation of the design-build Geopier Slope Reinforcement Technology (SRT ®) system with subsequent riprap slope reconstruction. Geopier SRT is a design-build system that drives plate piles through unstable soil into a competent layer using an excavator with a vibratory hammer. The piles induce soil arching effects on the landslide that provide resistance against downslope soil movement.
We performed a limit-equilibrium slope stability analysis using Method while incorporating the SRT system and riprap reconstruction in our analysis. The analysis results presented in this letter were obtained using the computer-aided program SLIDE©(Version 9.027).
The program analyzes circular slip surfaces within a defined start and end section as well as a specified search window. The start and end sections are generally identified at locations outside the top and toe of the slope of interest.
The soil parameters used in the analyses are summarized in Table 3 and are based on interpretation of the results of our laboratory tests as well as our experience with similar materials.

GEOTECHNICAL RECOMMENDATIONS FOR LANDSLIDE REPAIR Page 5 We performed the pseudo-static slope stability analyses in general accordance with guidelines 1g was
used to model slope stability under seismic shaking conditions using the simplified methods of Blake et al. (2002). This seismic coefficient was developed using a PGA of 1.00g as prescribed in the 2022 California Building Code, a mean Magnitude of 7.82, a distance of less than 10 km, and a threshold displacement of 15 centimeters.
Based on the results of the analysis, installation of the proposed SRT system and surrounding riprap will result in a static factor of safety above 1.5 and a seismic factor of safety above 1.0 against slope failure through the slide failure plane observed in our field explorations. The results are shown in Appendix C. The limit equilibrium slope stability analysis described above models the riprap as soil for strength characterization purposes, which resulted in shallow failures that propagated through the riprap surface in our model. It is our opinion that the analysis does not adequately model the frictional interactions between individual pieces of riprap that would increase the strength and stability of the riprap system; therefore, we do not consider the shallow failures indicated by the analysis to pose a risk to slope stability.
It is important to note that seismic displacement cannot be precisely predicted; however, based on the methods used for evaluating seismic stability, we anticipate seismic deformation for slopes within the subject site to be generally in the range of or less than 15 cm (6 inches). According to SP117A, slopes with a pseudo-static stability factor greater than 1.0, considering a seismic coefficient outlined above, are considered stable and correspond to limited landslide movement and damage.
CONCLUSIONS
Based on the findings of our study, it is our opinion that the landslide likely occurred within fills that were previously placed during the construction of the roadway and sidewalk along Dartmouth Avenue. Based on our borings and the geomorphology of the landslide, it is our opinion that the bottom of the landslide likely extends to an average depth of approximately 7 feet below the existing ground surface.
In our experience, landslide movement may continue for an unknown period of time until the landslide becomes dormant or repairs to mitigate the landslide are implemented. If left unmitigated, landslide areas may reactivate from seasonal weather fluctuations, seismic events, or other circumstances, and they may periodically creep over time as conditions fluctuate in and out of equilibrium. We provide our recommendations for corrective measures in the following section.
RECOMMENDATIONS
Based on the results of our slope stability analysis, it is our opinion that the slope can be stabilized with a combination of Geopier SRT installation and riprap slope reconstruction. Repair work should begin with the removal of all riprap placed in the slope failure area. We should approve the base of the excavation prior to SRT installation.
Plate piles from the SRT system should be driven to 9 feet below the existing ground surface (the 8-foot-long piles should be driven to at least 12 inches below future grade), in the configuration indicated on the plans prepared by Geopier dated September 20, 2023. The slope can then be reconstructed using light class (200 pound) angular shaped riprap that was removed prior to the SRT construction. The slope for the riprap reconstruction should closely match original grades prior to landslide (roughly a 1½:1 ratio horizontal to vertical).

GEOTECHNICAL RECOMMENDATIONS FOR LANDSLIDE REPAIR Page 6 Given the steep slope at this project site, careful placement of the riprap during construction is imperative. Riprap should be placed so that the larger angular rocks are interlocked and follow a definite pattern, with the voids between the larger stones filled with smaller stones and the surface kept relatively clean. The riprap material and placement should comply with Method A Placement of the Caltrans Standard Specification Section 72-2.

core. The geocomposite core shall be furnished with an approved method of constructing and connecting with outlet pipes. If the fabric on the geocomposite drain is torn or punctured, replace the damaged section completely. The specific drainage composite material and supplier shall be preapproved by ENGEO.
The Contractor shall submit a manufacturer's certification that the geocomposite meets the design properties and respective index criteria measured in full accordance with applicable test methods. The manufacturer's certification shall include a submittal package of documented test results that confirm the design values. In case of dispute over validity of design values, the Contractor will supply design property test data from a laboratory approved by ENGEO, to support the certified values submitted.
Geocomposite material suppliers shall provide a qualified and experienced representative onsite to assist the Contractor and ENGEO at the start of construction with directions on the use of drainage composite. If there is more than one application on a project, this criterion will apply to construction of the initial application only. The representative shall also be available on an asneeded basis, as requested by ENGEO, during construction of the remaining applications. The soil surface against which the geocomposite is to be placed shall be free of debris and inordinate irregularities that will prevent intimate contact between the soil surface and the drain.
Edge seams shall be formed by utilizing the flap of the geotextile extending from the geocomposite's edge and lapping over the top of the fabric of the adjacent course. The fabric flap shall be securely fastened to the adjacent fabric by means of plastic tape or non-water-soluble construction adhesive, as recommended by the supplier. To prevent soil intrusion, exposed edges of the geocomposite drainage core edge must be covered.
Approved backfill shall be placed immediately over the geocomposite drain. Backfill operations should be performed to not damage the geotextile surface of the drain. Also during operations, avoid excessive settlement of the backfill material. The geocomposite drain, once installed, shall not be exposed for more than 7 days prior to backfilling.

PART II - GEOGRID SOIL REINFORCEMENT
Geogrid soil reinforcement (geogrid) shall be submitted to ENGEO and should be approved before use. The geogrid shall be a regular network of integrally connected polymer tensile elements with aperture geometry sufficient to permit significant mechanical interlock with the surrounding soil or rock. The geogrid structure shall be dimensionally stable and able to retain its geometry under construction stresses and shall have high resistance to damage during construction to ultraviolet degradation and to chemical and biological degradation encountered in the soil being reinforced. The geogrids shall have an Allowable Tensile Strength (Ta) and Pullout Resistance, for the soil type(s) as specified on design plans.
The contractor shall submit a manufacturer's certification that the geogrids supplied meet plans and project specifications. The contractor shall check the geogrid upon delivery to ensure that the proper material has been received. During periods of shipment and storage, the geogrid shall be protected from temperatures greater than 140°F, mud, dirt, dust, and debris.
Manufacturer's recommendations in regard to protection from direct sunlight must also be followed. At the time of installation, the geogrid will be rejected if it has defects, tears, punctures, flaws, deterioration, or damage incurred during manufacture, transportation, or storage. If approved by ENGEO, torn or punctured sections may be repaired by placing a patch over the damaged area. Any geogrid damaged during storage or installation shall be replaced by the Contractor at no additional cost to the owner.
Geogrid material suppliers shall provide a qualified and experienced representative onsite at the initiation of the project, for a minimum of three days, to assist the Contractor and ENGEO personnel at the start of construction. If there is more than one slope on a project, this criterion will apply to construction of the initial slope only. The representative shall also be available on an as-needed basis, as requested by ENGEO, during construction of the remaining slope(s).
Geogrid reinforcement may be joined with mechanical connections or overlaps as recommended and approved by the manufacturer. Joints shall not be placed within 6 feet of the slope face, within 4 feet below top of slope, nor horizontally or vertically adjacent to another joint.
The geogrid reinforcement shall be installed in accordance with the manufacturer's recommendations. The geogrid reinforcement shall be placed within the layers of the compacted soil as shown on the plans or as directed. The geogrid reinforcement shall be placed in continuous longitudinal strips in the direction of main reinforcement.

CITY COUNCIL
STAFF REPORT
MEETING DATE: February 12, 2024
ITEM TITLE: Adopt a Resolution Authorizing the City Manager or Their Designee to Execute Agency-State Master Agreements for State and FederalAid Funded Projects.
RECOMMENDATION:
Staff recommends that the City Council adopt a Resolution authorizing the City Manager or their designee to execute future master agreements, which include agency-state agreements for federal-aid projects, program supplemental agreements, fund exchange agreements and/or fund transfer agreements for all transportation projects.
FISCAL IMPLICATIONS:
There is no fiscal impact for this item.
BACKGROUND:
The U.S. Congress and the California State Legislature may enact legislation to make federal or state funds available for local transportation projects. For example, Assembly Bill 102 was amended for the Budget Act of 2023, and included the award of Priority Legislative Budget Projects Funds, from which, $150,000 was awarded to the City of San Carlos for a Safe Routes to School Improvements and Paving Project.
Before any federal or state aid can be made available for a specific project, the administering agency (the City of San Carlos) and the California Department of Transportation (“Caltrans”) are required to enter into an agreement for all transportation projects. The agreements have no force or effect with respect to any program or project until a project-specific program supplemental agreement has been executed.
ANALYSIS:
Designating authority for certain agreements with Caltrans allows the City to accept funds to carry out state and federal-aid funded projects without delay in project schedule and allows for expedited execution.
ALTERNATIVES:
The alternatives available to the City Council include:
1. Adopt a Resolution authorizing the City Manager or their designee to execute agencystate master agreements for state and federal-aid funded projects; or

CITY COUNCIL
STAFF REPORT
MEETING DATE: February 12, 2024
ITEM TITLE: Adopt a Resolution Authorizing the City Manager to Enter Into a Power Purchase Agreement with Peninsula Clean Energy Authority to Deploy Solar Photovoltaic Systems at Designated City Facilities.
RECOMMENDATION:
Staff recommends that the City Council adopt a Resolution authorizing the City Manager enter into a power purchase agreement (PPA) with Peninsula Clean Energy Authority (“PCE”) to deploy solar photovoltaic systems (“Solar PV Systems”) at designated City facilities.
FISCAL IMPLICATIONS:
The Solar PV Systems would be financed through a PPA with PCE. Under a PPA model, PCE will arrange for the sourcing, installation, operations, and maintenance of the Solar PV Systems, and the City would pay an agreed upon price per kilowatt-hour (“kWh”) for power generated throughout the system’s life. There would be no upfront cost to the City for the Solar PV Systems.
For projects with solar power but no battery, the Solar PV Systems are expected to provide cost savings. The savings are expected to grow over time due to avoided increases in utility costs which are expected to rise as much as 5% or more per year.
If PCE is unable to offer a PPA rate for the Solar PV Systems that will provide the City with net savings or other community benefits as determined by the City, there is no obligation to move forward.
BACKGROUND:
The City of San Carlos is a joint power authority (JPA) member of PCE. As the community-led electricity provider for San Mateo County, PCE provides clean electricity at lower prices than Pacific Gas & Electric (PG&E) and offers innovative options in purchasing and generating electricity for residents and businesses.
In 2021, PCE kicked off a process with its JPA members, including the City, to identify facilities for the potential deployment of Solar PV Systems and pilot a new aggregate procurement model for its members that would help reduce the costs and complexities associated with financing, sourcing, installing, and maintaining Solar PV Systems.
On October 11, 2021, the San Carlos City Council adopted Resolution 2021-100 (see Attachment 2) authorizing the City Manager to partner with PCE to deploy a Solar PV System at the San Carlos Youth Center at 1001 Chestnut Street. As a result, a Solar PV System was successfully installed at the Youth Center in 2023 and was granted permission to operate by PG&E on January 16, 2024.
8.g
February 12, 2024 Packet Pg. 929
The Solar PV System at the San Carlos Youth Center was financed through a PPA with PCE.
There are several benefits to installing and financing Solar PV Systems on City facilities with a PPA with PCE. Some of the benefits are:
• PCE arranges for the procurement, construction, operations, and maintenance of the Solar PV System at highly competitive rates due to its aggregate procurement model for member cities;
• There is no upfront cost to the City for the Solar PV Systems. Also, if PCE is unable to offer a PPA rate for the Solar PV System that will provide the City with net savings or other community benefits as determined by the City, there is no obligation to move forward; • The City pays an agreed upon price per kWh for the power generated throughout the system’s 20-year life and is therefore able to hedge against rising utility rates which are expected to rise as much as 5% or more per year;
• The City obtains the financial and environmental benefits of a Solar PV System with no upfront costs and without incurring significant staff time and costs; and • The City creates a local, renewable energy source consistent with Strategy 6 of the City’s Climate Mitigation and Adaptation Plan which encourages the City to “continue to support and increase participation in rooftop and onsite solar energy systems in the community and at City facilities.”
ANALYSIS:
PCE has started the second phase of its local government distributed solar program, GovPV2, for JPA members. With the successful completion of the pilot project at the Youth Center, City staff is considering the potential deployment of Solar PV Systems at other City facilities, such as the Library at 610 Elm Street, the Adult Community Center at 601 Chestnut Street, and any other City facilities that may be identified.
Recently, the California Public Utilities Commission updated tariffs governing solar PV resources.
The next iteration of solar tariffs, known as the Net Billing Tariff (NBT), will be less advantageous for solar-only projects and will negatively affect project economics. In order to benefit from the current, more favorable NEM tariffs, construction for solar-only projects must completed within three years of the interconnection application, which was submitted by PCE in April 2023. For this reason, the following actions must be taken to ensure that JPA member projects are deployed as soon as possible:
1. Select Contractor – Completed. PCE has already completed the competitive selection process to identify the vendors who will be awarded contracts to install the projects.
2. JPA Member Review of New PPA Terms – Completed. The City Attorney and staff have reviewed the updated PPA and determined that it is substantially similar to the previous PPA with the City.
3. Commitment Resolution – Due February 2024. PCE requests resolutions from participating JPA members’ legislative bodies and executive teams to demonstrate their interest in the GovPV2 process. Showing commitment via a resolution helps PCE secure
8.g
February 12, 2024 Packet Pg. 930
the best available pricing from vendors by giving vendors a high level of confidence in the participating members’ intention to execute. The Resolution that the Council is being asked to adopt delegates authority to the City Manager to sign the new solar PPA if the project, with proposed final pricing, is determined by staff to be beneficial to the City.
4. Execution of New PPA – Due February 2024 prior to site visits. Upon execution of the attached Resolution, staff will execute a new PPA with PCE.
5. Site Visits – Due February 2024. The goal of site visits is to produce final system designs for proposed City facilities with cost efficiencies in mind, which may result in PPA rate reductions. Teams will consider the feasibility of battery storage during these site visits.
6. Approve PPA Rate – March 2024. Under the PPA, PCE will propose a price per kWh for power generated throughout the system’s life. If PCE is unable to offer a PPA rate for the proposed Solar PV Systems that will provide the City with net savings or other community benefits determined the City, the City has no obligation to move forward with the project(s).
7. PCE to Finalize Interconnection Application Agreement with PG&E – April 2024.
8. Projects Completed by April 2026. PCE will schedule projects with the contractors.
Construction for solar-only projects must be completed within three years of the interconnection application, which was submitted in April 2023.
ALTERNATIVES:
The alternatives available to the City Council include:
1. Adopt a Resolution authorizing the City Manager to enter into a PPA with PCE to deploy Solar PV Systems at designated City facilities; or
2. Do not adopt the Resolution; or
3. Provide staff with alternative direction.

CITY COUNCIL
STAFF REPORT
MEETING DATE: February 12, 2024
ITEM TITLE: Appoint Rosie Jimenez and Kim Norgaard as Alternate Members on the City Centennial Advisory Committee.
RECOMMENDATION:
Staff recommends that the City Council appoint Rosie Jimenez and Kim Norgaard as alternate members on the City Centennial Advisory Committee (“Advisory Committee”) representing the Kiwanis Club and the San Carlos School District (respectively).
FISCAL IMPLICATIONS:
Funding for the City’s centennial celebration (C2309) has been appropriated in the adopted fiscal year (FY) 2023-25 Capital Improvement Budget: $250,000 in FY 2023-24 and $750,000 in FY 2024-25. There are no funding implications associated with appointing members to the Advisory Committee.
BACKGROUND:
To assist with putting together the program of events to celebrate the Centennial, the City Council appointed 22 community members representing multiple interests of the community to serve as the “Primary” members of the City Centennial Advisory Committee. The Advisory Committee also consists of 17 “Alternate” members. The Advisory Committee’s role is to provide ideas and input throughout the planning process. Ideally, Advisory Committee members will also participate in the celebrations.
Advisory Committee members will serve until the conclusion of the Centennial celebrations.
Committee members will attend planning meetings throughout 2024 and continue with meetings throughout 2025, if needed. This is a volunteer appointment and committee members will not receive compensation for their service. Committee members are required to either work or reside in San Carlos.
On January 24, 2024, the first Advisory Committee meeting was held. Thirty-two committee members attended the meeting. The City Clerk provided a brief orientation before swearing in the appointed members. To conclude the meeting, members were asked to share their top idea for how the City and community can celebrate the Centennial.
ANALYSIS:
Following the City Council’s initial appointments, City staff was notified that the Kiwanis Club alternate member was no longer able to fulfill their committee role. Additionally, prior to the City
8.h
February 12, 2024 Packet Pg. 936
Council appointments, the School District was not able to appoint an alternate member to the Advisory Committee.
Following the first meeting, City staff followed up with both organizations. A new alternate member, Rosie Jimenez, was selected to represent the Kiwanis Club. Rosie is advisor of Carlmont High School Key Club, a division of the Kiwanis Club. Furthermore, the School District notified City staff that Kim Norgaard will serve as the School District alternate member. Kim has been in the San Carlos School District for 30 years. She has served as a teacher at White Oaks Elementary School and is currently the principal at Arundel Elementary School.
Should the City Council appoint Rosie Jimenez and Kim Norgaard as alternate members on the City Centennial Advisory Committee, the City Clerk and City Attorney will provide an orientation prior to the next committee meeting on Wednesday, February 21, 2024.
Going forward, any primary member vacancies on the Advisory Committee will be filled by an alternate member. In the event an alternate member seat becomes vacant, it will not be filled as the Advisory Committee consists of 17 alternate members.
ALTERNATIVES:
The alternatives available to the City Council include:
1. Appoint Rosie Jimenez and Kim Norgaard as alternate members on the City Centennial Advisory Committee representing the Kiwanis Club and the San Carlos School District (respectively); or
2. Leave the City Centennial Advisory Committee's Kiwanis Club and San Carlos School District’s alternate members seats vacant; or

1 CITY COUNCIL
STAFF REPORT
MEETING DATE: February 12, 2024
ITEM TITLE: Discuss the Northeast Area Specific Plan and Consider Endorsing the Revised Draft Land Use Option and Urban Design Framework.
RECOMMENDATION:
Staff recommends that the City Council receive a presentation and consider endorsing the Revised Draft Land Use Option and Urban Design Framework for the Northeast Area Specific Plan.
FISCAL IMPLICATIONS:
There are no fiscal implications for this item.
BACKGROUND:
The Northeast Area is defined as the area north of Holly Street, to the San Carlos City limits at Belmont Creek, and between Highway 101 and Old County Road (see Figure 1).
Over the last several years, the East Side of San Carlos, including the Northeast Area, has received significant interest from developers, mostly from the life sciences biotechnology sector.
Because the area is likely to change within the next few years, as part of the City of San Carlos Strategic Plan, the City Council directed staff to create a Specific Plan to thoughtfully plan for, manage, and direct change in the Northeast Area. The City Council further directed staff to explore the possibility of introducing housing to the Northeast Area.
The Northeast Area Specific Plan will be a comprehensive policy document which guides change and growth in the Northeast Area over the next 20 years. (See attachment 3 for an outline of the topics that will be included in the Northeast Area Specific Plan.)

February 12, 2024 Packet Pg. 938
2 Figure 1. Map of the Northeast Area Specific Plan Boundaries The Northeast Area Specific Plan includes three primary themes: Flooding and Resilience; Transportation and Parking; and Land Use and Placemaking. During the spring and summer of 2023, City staff and the consultant team developed draft “scenarios,” or options for resiliency, flooding, transportation, and parking with different approaches to land use, including housing.
Specifically, three land use options were developed: Option 1: All Employment; 2A: Employment + Housing; and 2B: Employment + More Housing (see Figure 2).
A Study Session with the Planning and Transportation Commission (PTC) was held on September 18, 2023 and a Study Session with the City Council (CC) was held on September 25, 2023. The primary focus of these study sessions was to review the three initial draft land use options. (See attachment 2 for a more detailed look at the initial draft land use options.) Figure 2. Initial Draft Land Use Options- Summer 2023
On January 16, 2024, the project team presented the Revised Draft Land Use Option and Urban Design Framework for the Northeast Area to the Planning and Transportation Commission. This
9.a
February 12, 2024 Packet Pg. 939
3 Revised Draft Land Use Option and Urban Design Framework was developed with input from the Planning and Transportation Commission, City Council, and continued discussions with stakeholders, including property and business owners and Greater East San Carlos (GESC) residents. (See attachment 4 for links to the staff reports and meeting minutes from the September 18, 2023 Planning and Transportation Commission, September 25, 2023 City Council, and January 16, 2024 Planning and Transportation Commission Study Sessions.) ANALYSIS:
The Draft Revised Land Use Option includes 5 Urban Design Frameworks that were modified based on stakeholder input including:
1. Mobility Network
2. Resilience Framework
3. Land Use Plan
4. Ground Floor Activation
5. Heights and Density
Mobility Network
Initial iterations of the Mobility Network proposed new public streets and productive alleys (publicly accessible on private property) within the district; specifically, extending Bragato Road from the current dead-end to Industrial Road and creating a new north-south street parallel to Glenn Way.
These new streets were proposed, along with other concepts, to address transportation and parking management throughout the district. The goal was to support people who walk, bicycle, take transit, and drive to the district, as well as freight and vehicle movement to support the businesses.
One major concern the project team heard from property owners was that they may be potentially impacted by the newly proposed streets or productive alleys cutting through their private properties. Another concern was that the proposed new roads did not consider parcel lines and separate ownership. To address these concerns, the project team made modifications to the proposed Mobility Network as seen in Figures 3A, 3B, and 3C.

• Trail along Belmont Creek with setback
• Pedestrian / Bicycle Connection to Belmont Creek from Quarry Road • Old County Road continues Eastside Connect Street Improvements • Pedestrian connection for District-Neighborhood Connectivity • Industrial Road redesigned as a multi-modal district boulevard Resilience Framework
Addressing environmental resilience and planning for future flood events is another primary focus of the Northeast Area specific Plan. The project team incorporated recommendations to increase environmental resiliency throughout the district. The initial concepts also proposed a community amenity in the triangular parcel next to Bragato Road. The goal was to indicate a provision to provide open space and community amenities for employees and residents within the district.
However, concerns were expressed that the proposed new community amenity in the triangular piece would limit future development possibilities for that property. Considering the feedback received about the proposed environmental resilience and open space concepts, the project team modified the initial concepts as seen in Figure 4A and 4B.

Proposed Resilience Framework
• Enhanced green stormwater infrastructure on Old County Road and Bragato Road • Regraded creek bank with landscaped setback to effectively manage flooding events and sea level rise
• Implement the storm drainpipe improvements identified in Storm Drain Master Plan (2017) in coordination with street design
• Enhanced green stormwater infrastructure on the eastern edge of Industrial Road • Enhanced greens stormwater infrastructure on the Southern edge of Taylor Way The goal of these modifications is to ensure the new proposed elements address the key concerns from stakeholders while also addressing the key project goals to:
• Improve access for all modes of transportation, and
• Champion district resiliency, and
• Address flooding issues and other environmental issues.
Revised Draft Land Use Option
Based on the input from the Planning and Transportation Commission, the City Council, and key stakeholders, the project team developed a Revised Draft Land Use Option. See figure 5 for the revised land use option for the Northeast Area.
9.a
February 12, 2024 Packet Pg. 945
9 Figure 5: Revised Draft Land Use Option
To address the concern of displacing existing light industrial businesses within the area, existing light industrial uses would continue to be allowed. In addition, the proposed ground floor uses within the light industrial area would activate the streets by allowing for traditional retail, professional services, and new light industrial/maker spaces. To address the need for open space and community amenities, the star on the map above marks the potential for a community amenity required as part of the redevelopment of the Williams Business Park. (See attachment 1 for a detailed look at the Revised Draft Land Use Option.)
Examples of allowable land uses in the Light Industrial area:
• Light Industrial, Warehousing, Service Commercial
• Research and Development, Biotechnology
• Retail and Neighborhood Services
• Small Scale Industrial, Artisan, Manufacturing
This Revised Draft Land Use Option also incorporates residential use in specific subareas. The southern portion of the district was identified as an ideal location for future housing as its within walking distance to public transit, El Camino, and Downtown. Residential would be allowed in two distinct land use classifications: “Mixed-Use (Residential, Ground Floor Commercial)” and “Residential” as shown in the orange and light-yellow areas of Figure 5.
Examples of allowable land uses in the Mixed-Use and Residential area:
• Mixed-Use (Residential, Ground Floor Commercial)
• Multifamily Family Residential
• Small Scale Industrial, Artisan, Manufacturing
• Retail and Neighborhood Services
9.a
February 12, 2024 Packet Pg. 946
10 Ground Floor Activation
The Revised Draft Land Use Option also proposes three district gateways, which would be activated by required ground floor retail to create social destinations. Retail uses are also encouraged along major corridors. This option aims to enhance small scale industrial spaces along Quarry Road and Glenn Way by requiring new development along this row to provide a percentage of ground floor space for small scale industrial, artisan, and manufacturing spaces.
The intent is for ground floor retail to be included with major redevelopments or completely new developments.
Proposed Base and Bonus Heights- Light Industrial Land Use Existing land uses within the existing Light Industrial zoning classification would continue to be allowed. However, changes to the height and floor area ratio (FAR) require modification to enable the desired built environment in the future. The project team is proposing a strategy whereby the base maximum height would be limited to 75 feet (current limit); and additional height (i.e. bonus height) would only be allowed for future developments if community benefits are provided.
At the January 16, 2024 Planning and Transportation Commission Study Session, the project team received feedback to further investigate bonus height limits in the light industrial subareas.
After reviewing the Airport Land Use Compatibility Plan (ALUCP), the project team lowered the initially proposed bonus height of 200 feet in the high intensity subarea to 155 feet to conform with the current ALUCP maximum height requirements. The long-term policy approach is to ensure that the height requirements in the Northeast Area Specific Plan remain consistent with the ALUCP height requirements as they change and update over time.
In summary, bonus heights and FARs will be tied to a community benefit system to ensure that high intensity development provides tangible community benefits. Community benefits are important to consider because with new land uses comes investment in critical social infrastructure and community amenities to support a growing City. The community benefits menu will be developed in upcoming months with City leadership input.
Examples of community benefits may include:
• Public Open Space
• Belmont Creek Restoration
• Green Infrastructure
• Community Facilities
• Industrial Business Retention
• Affordable Commercial Space
• Multi-Modal Street Improvements

*155 feet (ft.) is consistent with maximum height as set forth in the ALUCP Proposed Base and Bonus Heights- Mixed-Use and Residential Land Uses The proposed mixed-use area also has the option of bonus height. The maximum base height in the mixed-use area is proposed at 75 feet, which is the current standard; the bonus height is proposed at a maximum of 120 feet. Examples of public benefits as part of bonus height allowances would be similar to the ones listed above for light industrial. The maximum base height for the residential subarea is proposed at 75 feet with a required stepdown of 35 feet. The intent of the required stepdown is to facilitate a transition to the adjacent existing single-family neighborhood to the south. No bonus height provisions would be allowed in this residential area, except if a developer requests such to utilize the State Density Bonus Law. Additionally, if the mixed-use area is redeveloped, a public community amenity will be required as indicated by the star on the map. (See attachment 1 for a detailed look at the proposed base and bonus heights for the Light Industrial, Mixed-Use, and Residential land uses.)

RE: Northeast Area Specific Plan
My name is Carlos Hernández, General Manager of Delta Star located on the Corner of Industrial Rd. and Taylor Way Rd. As mentioned before:
We have been at the current location since the 1950s.
We are 100% Employee Owned and the largest, American-owned, medium power transformer manufacturer in the United States.
We provide work to over 260 people and expect to reach 340 by the end of 2026.
We currently utilize every inch of our property and could potentially use more in the future.
The areas of concern with the revised proposal are the following: - Safety: We are a twenty-four – seven operation, and the plan needs to consider the large safety risk not only to our employees but to potential citizens and pedestrians in the area considering the logistics of all vehicles that come in and out of our property. - Roads: The proposed Boulevard on Industrial Rd. does not consider that approximately 90% of our product shipments block all four lanes on Industrial Rd. for it to come out of our property due to the multi-axle trailers required. In fact, any extension to the existing center median that is south of us would restrict us from shipping our products. - Business continuity: How would we be protected as a business knowing that having a residential area across the street will have inevitable protests wanting us to move and close. - Growth: Our business continues to grow, and we are currently restricted in land, so if we acquire neighboring property, could we incorporate it into our land use? - Definition of “Light Industrial”: As discussed during the Property Owners Stakeholder Meeting on December 13 of 2023, the term “Light Industrial” might not be applicable to us and needs further review.
We will continue to participate in the Area Development plans and invite the members of the Planning Staff and City Council to visit our facility and see our operation firsthand to fully understand the potential impacts.

City of San Carlos, Planning and Transportation Commission, February 2, 2023 RE: Northeast Area Specific Plan
As General Manager of Delta Star, I want to share some of our comments, concerns, and suggestions regarding the new revised Area Development Plan.
As background, Delta Star is a Power Transformer and Substation Products manufacturer located on the North Corner of Industrial Rd. and Taylor Way Rd.
We have been in our current location since the 1950s.
We are a 100% Employee-Owned Company and the largest, American-owned, medium power transformer manufacturer in the United States.
We are and have been for a very long time one of the top 5 tax contributors to the City of San Carlos and previously to Belmont.
We provide work to over 260 people and expect to reach over 340 by 2026.
We currently utilize every inch of our property and are looking for more space.
To provide a better perspective of our operation, here is a short video ‘A Day at DSW” that provides insight to our day-to-day operations.

As we know, there are many challenges with a mixed industrial and residential area. Streets are one of the major concerns. The current plan proposal is for the entrance to be on Taylor Way Rd. and there were also conversations related to doing it on Industrial Rd. However, as you can see on the video titled ‘Driving Power’ we perform major operations that block Industrial Rd. for 35 to 45 minutes. These operations are performed around 14 times per month, all during daytime and some require CHP escort, which is tied to their schedule on days and times. We also perform similar operations on Taylor Way Rd. blocking the street 6 to 8 times a month. With our growth plans these maneuvers would increase ~40% to 60%.

Safety for our employees and for pedestrians is of high concern. We are a 24 X7 operation with many vehicles in multiple shifts, trucks and special maneuvers as shown in the videos are required daily on Industrial Rd and Taylor Way Rd. The new proposal needs to make sure that all these are considered without placing anybody in an unsafe situation. Will the sidewalks be wider, will there be barriers, so people don’t get onto the street, are underground passages being considered, etc.
Parking is another area of large concern. We have parking for our employees, but this is a daily issue throughout the City of San Carlos, and clear rules for multi-housing development need to be established. It would be beneficial to have a census of the amounts of vehicles owned by household in San Carlos to request the proper parking spaces per apartment.

If after all the proper studies and development, it is determined that housing will be built in that area, we recommend that the access to the housing development is from the Southwest where there is already an existing residential area, to avoid interference with our existing operations and traffic issues in the future.
There is also a proposal to convert Industrial Rd. into a ‘Boulevard’, although it is not clear and still needs to be defined, as shown on the video “Driving Power”, it needs to be very carefully studied before a Boulevard can be defined for Industrial Rd.
The term “Light Industrial’ needs to be clearly defined to include an express provision that Delta Star remains as legal conforming even if the scope of the products is adjusted since we are continuously evolving to meet market demands.

Storm drain and sewer system are areas of concern. We were substantially damaged and affected during the storms of December 31, 2022, and January 1, 2023, and know that the current rain drain system is not enough to withstand heavy storms, the addition of more houses will only increase the utilization of the current systems. Due to the City growth, the streets become creeks and rivers and the water goes down and ends in front of our property due to the way the street was built. A very detailed analysis of this situation needs to be done and new infrastructure in place to avoid the recurrence of these situations.
Industrial Rd. Dec-31-22 (W E) Industrial Rd. Dec-31-22 (S N) Taylor Way Rd. Jan-1-23 (W E) Recognizing the importance of our business being a top 5 tax contributor to San Carlos and the uniqueness of our operations and the proximity to the areas being proposed for residential, we will continue to participate with City Staff and those involved in the Area Development plans and invite interested parties to visit our facility and see firsthand the operations.
Regards,
Carlos Hernandez

PLANNING & TRANSPORTATION COMMISSION STUDY SESSION, JANUARY 16, 2024 AND CITY COUNCIL STUDY SESSION, FEBRUARY 12, 2024
The City of San Carlos, supported by the Perkins&Will consultant team, has developed a revised draft land use option for consideration by the Planning and Transportation Commission and City Council in January and February of 2024.
The purpose of the meetings is to select a preferred land use scenario to guide the preparation of the Northeast Area Specific Plan. (www.sancarlosnortheastplan.com).
REVISED DRAFT LAND USE OPTION FOR CONSIDERATION: NORTHEAST AREA, SAN CARLOS Revised Draft Land Use Option, January 2024, City of San Carlos The revised draft land use option is based on input received in the fall and winter of 2023 from the community, stakeholders, and the City of San Carlos’ Planning and Transportation Commission and City Council.
Two previous iterations were shared with the community during the fall 2023 workshops, in-person pop-up events, online survey, a study session with the Economic Development Advisory Commission, and meetings and conversations with property owners, business owners, and stakeholders. These initial iterations were subsequently presented to the Planning and Transportation Commission and City Council in September 2023 for review and guidance.
