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 Engineer with duplicate licensed Weighmaster’s certificates showing the actual net weights. The City will accept the certificates as evidence of the weights delivered.
10.02 Bid Items - Should any bid item be eliminated in its entirety, payment will be made to the Contractor for actual costs incurred, in connection with such eliminated contract work, and for costs incurred prior to the date of the Engineer’s written notification eliminating such work. The actual costs to be paid to the Contractor shall be computed in the same manner as if the work were to be paid on a force account basis. 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%) of the contract’s 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.

3. All information relative to Contractor’s sole responsibilities and of means, methods, techniques, sequences and procedures of construction and safety precautions and programs incident thereto.
G. Contractor’s submission to City or to Engineer of a Shop Drawing or Sample submittal will constitute Contractor’s representation that it has satisfied its obligations under the Contract Documents, and as set forth immediately above, with respect to Contractor’s review and approval of that submittal.
H. Designation of work “by others”, if shown in submittals, shall mean that work will be responsibility of Contractor rather than subcontractor or supplier who has prepared submittals.
I. The Contractor shall sign a statement with each submittal, certifying that the submittal has been checked by the Contractor and is in conformance with the Specifications. Any submittal received without this certification shall be returned AMEND AND RESUBMIT and count as one submittal under R.5.a of this specification section.
J. After review by City or Engineer of each of Contractor’s submittals, two (2) sets of material will be returned to Contractor with actions defined as follows:
1. NO EXCEPTIONS TAKEN – A formal revision and resubmission of said submittal will not be required. Accepted subject to its compatibility with future submittals and additional partial submittals for portions of the work not covered in this submittal does not constitute approval or deletion of specified or required items not shown on the submittal.
2. MAKE CORRECTIONS NOTED (NO RESUBMISSIONS REQUIRED)
Same as 1 above, except that minor corrections as noted shall be made by Contractor.
3. AMEND AND RESUBMIT - Rejected because of major inconsistencies or errors that shall be resolved or corrected by Contractor prior to subsequent review by Engineer.
4. REJECTED - The submittal is illegible or the submittal is so far out of compliance with the contract documents that the Contractor needs to try again, from scratch.

CITY COUNCIL
STAFF REPORT
MEETING DATE: June 10, 2024
ITEM TITLE: Adopt a Resolution Ratifying the Proposed Budget for Fiscal Years 2024-26 for the Belmont-San Carlos Fire Department ("BSCFD").
RECOMMENDATION:
Staff recommends that the City Council adopt a Resolution ratifying the proposed Fiscal Years (“FY”) 2024-26 Budget for the Belmont-San Carlos Fire Department (“BSCFD”).
FISCAL IMPLICATIONS:
The costs associated with the ratification of this budget total $2,096,897 in Fiscal Year (FY) 2024- 25 and $2,325,734 in FY 2025-26. These costs have been incorporated into the Proposed FY 2025-26 Mid-Cycle Budget adjustments.
BACKGROUND:
On October 1, 2010, the City terminated service with the BSCFD. As a result of the termination, on September 30, 2011, the BSCFD dissolved. Although the department has been dissolved, the entity will continue to exist until the last remaining obligation has been paid. The cost allocation formula set forth in the Joint Powers Agreement (JPA) stipulates that the Belmont Fire Protection District pay 47.1%, and the City of San Carlos pay 52.9%, of the total costs.
The BSCFD prepares a two-year budget that is developed by the staff and presented to the four- member BSCFD JPA Board of Directors consisting of San Carlos City Councilmembers John Dugan and Ron Collins, and Belmont City Councilmembers Julia Mates and Tom McCune. Once the Board of Directors reviews and approves the Proposed Budget, the Proposed Budget and any Budget Amendments are forwarded to the governing bodies of the two parent agencies (Belmont Fire Protection District and City of San Carlos) as a Major Decision under the JPA terms for review and ratification. The BSCFD Board of Directors approved the Proposed FY 2024-26 Budget at its meeting held on May 14, 2024, via BSCFD Resolution 2024-01.
ANALYSIS:
The attached FY 2024-26 Budget reflects the BSCFD obligations in a post-operations era since the September 30, 2011 dissolution. As such, the budget generally includes non-discretionary expenditures. Important highlights include the following:
1. Below is a summary of the outstanding pension obligations based on CalPERS’s June 30, 2022, actuarial valuation:
8.n
June 10, 2024
Packet Pg. 398
Plan Unfunded Actuarial Liability
Safety $33,949,091
Miscellaneous $1,103,621
In furtherance of retiring these obligations, the Budget includes payments to CalPERS of $4,405,051 in FY 2024-25 and $4,420,017 in FY 2025-26. These amounts factor in a prepayment of the contribution in one annual payment at the beginning of each fiscal year, and no additional discretionary payments towards retiring the obligation. The FY 2024-25 and FY 2025-26 costs reflect CalPERS’s investment returns of -7.5% and 6.1% as of June 30, 2022, and June 30, 2023, respectively, and a discount rate of 6.8%.
2. The outstanding postretirement health benefit obligation, net of plan assets in the California Employers' Retiree Benefit Trust (CERBT) fund, is $1,059,993. The Budget includes Other Post-Employment Benefits (OPEB) benefit payments made on a pay-go basis for retirees and surviving spouses who have earned lifetime medical coverage, $178,791 in FY 2024-25 and $183,943 in FY 2025-26.

Belmont-San Carlos Fire Department
Budget Fiscal Years 2024-25 and 2025-26
Budget Summary
The proposed Fiscal Years 2024-25 and 2025-26 Budgets reflects the Belmont-San Carlos Fire Department’s (Fire Department) obligations in a post-operations era since the September 30, 2011 dissolution. The Budget funds the following wind-down activities of the Department:
▪ Below is a summary of the outstanding pension obligations based on CalPERS’s June 30, 2022 actuarial valuation:
Plan Unfunded Accrued Liability
Safety $33,949,091
Miscellaneous $1,103,621
In furtherance of retiring these obligations, the Budget includes payments to CalPERS of $4,405,051 in FY 2024 -25 and $4,420,017 in FY 2025 -26. These amounts factor in a prepayment of the contribution in one annual payment at the beginning of each fiscal year, and no additional discretionary payments towards retiring the obligation. The FY 2024-25 and FY 2025-26 costs reflect CalPERS’s investment returns of -7.5% and 6.1% as of June 30, 2022 and June 30, 2023, respectively, and a discount rate of 6.8%.
▪ Based on the June 30, 2023 actuarial valuation performed by the Fire Department’s actuary, Foster & Foster, the outstanding postretirement health benefit obligation, net of plan assets in the California Employers' Retiree Benefit Trust (CERBT) fund, is $1,059,993. The Budget includes Other Post-Employment Benefits (OPEB) benefit payments made on a pay-go basis for retirees and surviving spouse who have earned lifetime medical coverage, $178,791 in FY 2024-25 and $183,943 in FY 2025-26.
▪ The estimated liability for unpaid loss and allocated loss adjustment expenses ranges from $175,000 (70% confidence level) to $404,000 (90% confidence level) estimated as of June 30, 202 5 for o utstanding workers compensation claims from past employees . The Fire Department estimates claims payments of $18,340 in FY 2024-25 and $18,969 in FY 2025-
26. As a result of the above activity and the need to maintain the reserve requirement discussed below, contributions paid by the member agencies increase modestly in FY 2024-25 and FY 2025-26 as follows: Belmont Fire Protection District ($1,869,949 in FY 2024-25 and $2,073,797 in FY 2025- 26 - 47.1%) and the City of San Carlos ($2,0 96,897 in FY 2024-25 and $2,325,734 in FY 2025- 26 - 52.9%).
The Budget assumes a fiscal reserve of $452,428 in FY 2024-25, and then lowering the reserve to $150,000 in FY 2025-26, which is the stated minimum reserve for the entity.

APPENDIX
What is the Basis for the Belmont-San Carlos Fire Department Budget? The Belmont-San Carlos Fire Department prepares its budget using the modified accrual basis of accounting whereby revenues are recognized when they become measurable and available.
Likewise, expenditures are recognized when an event or transaction is expected to draw upon current spendable resources.
What are the Budgetary Policies of the Belmont-San Carlos Fire Department? The Belmont-San Carlos Fire Department operates under a set of budget policies which guide the development of the budget. These policies are presented below.
• Where possible, General Fund revenues, operating expenditures and transfers should balance on a "current" basis.
• Supplemental appropriations during the fiscal year require an appropriations adjustment resolution to be passed by the Fire Board.
• In cases where there is an increase in the size of the budget due to an appropriation increase, the resolution requires an offsetting change in fund balance, unless the added cost is accompanied by an unanticipated increase in revenue to the General Fund. If such an offset occurs then there is no change to the fund balance, but the increase in revenue and the source of that revenue is to be shown in the appropriations adjustment resolution.
• Where the increased appropriation is to be funded from a restricted source and no offsetting revenue is identified, the resolution must show a decrease in fund balance from the balance that was expected when the budget was adopted.
What are Funds?
Perhaps the biggest perplexities encountered by someone examining the budget or financial statements of a government agency for the first time is the existence of numerous "funds." Whereas even the largest commercial enterprise generally will report only a single amount for each item in its financial statements (e.g., "cash," "sales"), governments, both large and small, will typically report a number of separate columns or "funds."
Each of these funds is considered to function as a separate fiscal and accounting entity. Funds are normally used by governments to segregate resources related to specific activities (e.g., general operations, capital projects). For most governments, the principal operating fund is known as the "General Fund."
8.n
June 10, 2024
Packet Pg. 408
What Different Kinds of Funds do Governments Use?
Governments may use any number of individual funds in their budgeting and financial reporting (although they are encouraged to use the least number of funds practical in their specific circumstances). Regardless of the number of individual funds used, generally accepted accounting principles (GAAP) require all of these individual funds to be aggregated into no more than seven specified "fund types" on the combined balance sheet.
Four of these fund types are known as the "governmental funds." They are the General Fund, the special revenue funds, the debt service funds, and the capital project funds. These funds are typically used to account for most of a government's operations and capital expenditures.
Two other funds types are known as the "proprietary funds" because they function in a manner similar to private enterprise. These funds are the enterprise (or service) funds and the internal service funds. The last of the seven fund types that may be found on a government’s combined balance sheet or in a budget document is the trust and agency fund. The Belmont-San Carlos Fire Department only uses a General Fund.
General Fund
The General Fund is used to account for the financial resources and expenditures associated with most Department operations where revenue is not required to be recorded in a separate fund. As the name implies, revenues collected in this fund are not restricted as to which division or purpose they may be expended.
The sources of revenue for the General Fund are primarily from service charges and the use of money and property held by the Department.
Is "Unassigned Fund Balance" a Good Measure of Economic Health? "Unassigned” or “available” fund balance is not designated to reflect economic health but simply to provide a measure of the financial resources available for future spending or appropriation. While an absence of spendable resources may well be an indication of actual or potential economic problems, the presence of such resources is no guarantee of sound economic health. For example, just as an individual can increase his or her checkbook balance by taking out a loan, so too can a governmental fund increase its spendable resources (i.e., " unassigned fund balance") by issuing long-term debt.
In neither case would the economic position of the individual or government be improved because the debt must be repaid. Accordingly, a significant level of " unassigned fund balance" should not be taken alone as evidence of sound economic health. Rather, users of government financial statements should also take care to evaluate future claims on governmental fund assets when assessing the economic health of a governmental fund. In particular, users should be careful to consider a governmental fund's oblig ation to finance long-term debt (reported separately in the general long-term debt account group), as well as the potential future drain on governmental fund resources posed by deficits in other funds (e.g., enterprise funds).

How High a Level of "Unassigned” or “Available” Fund Balance Should be Maintained in the General Fund?
There is little argument that a deficit "unassigned” or “available” fund balance is normally to be avoided. Indeed, such deficits are illegal in a number of jurisdictions. The "right amount" of unassigned fund balance, however, is a question open to debate, particularly in the General Fund. Bond raters and others often use "rules of thumb" to measure the adequacy of unreserved fund balance in the General Fund. For example, 5 percent of annual operating expenditures is a commonly used amount. Others argue that unassigned fund balance should equal no les s than one month's operating expenditures (i.e., 8.3%). Care must be taken, however, to avoid applying such rules of thumb mechanically. A variety of factors must be taken into account when evaluating the adequacy of fund balance in the General Fund.
One important consideration is the reliability of a governmental agency's revenue sources.
Whereas some governmental revenues are traditionally quite stable, others often can vary significantly depending on conditions in the economy (e.g., interest income). Governments depending upon less reliable revenue sources may need to maintain significantly higher levels of unreserved fund balance than those relying upon more stable sources of revenue.
Another important factor is the timing of cash inflows and outflows. Governments whose cash flows are less predictable or uneven because of the timing of revenue collections may need relatively higher levels of unreserved fund balance to maintain liquidity than those with highly predictable continuous cash inflows and outflows.
A third important consideration involves resources available in other funds. Some governments, for example, establish separate "budget stabilization funds" to meet unexpected contingencies. When such additional resources are available in other funds, a lessor amount of unreserved fund balance may be appropriate in the General Fund.
In short, the specific financial history, prospects and circumstances of each individual government must be carefully weighed when evaluating the adequacy of "unassigned fund balance."
In Belmont-San Carlos Fire Department's case, the revenue stream is stable, predictable and known. Accordingly, the Board has not set an established policy on the balance of unassigned fund balance of the General Fund.
Why Does the Department Prepare a Budget?
Any government entity prepares a budget for more than one reason. The first is that it has a legal obligation to do so. But of equal importance, for Belmont-San Carlos Fire Department, is that the budget sets forth the basic spending policy of the Fire Board.
8.n
June 10, 2024
Packet Pg. 410
Every other year the Board adopts a bi-annual budget for the upcoming two fiscal years. The Department's fiscal year begins on July 1st. Th e budget, therefore, will remain in effect through June 30th. There are two major sections of the budget. The revenue side describes the sources and amounts of revenue the Department expects to receive over the fiscal year period. The expenditure or appropriations side describes how much money will be spent from either current revenues or from existing fund.
A final important purpose to remember about the budget document is that it is a plan. The projected revenues and the expenditures are estimates. Many incidents can happen throughout a year to change either revenue expectations or expenditure needs. The Department tries to budget as accurately as possible. Should things change, however, there is a process in place to amend the budget document. Supplemental appropriations resolutions are presented to the Board during the budget cycle to add appropriation s. Sometimes these changes will be accompanied by an offsetting additional source of revenue, neutralizing the possible impact on the expected ending fund balance of the relevant fund. Other times these changes will require fund balances be used, reducin g the amount of the fund balance from what was projected at the beginning of the year.
How Does the Department Prepare its Budget?
The Belmont-San Carlos Fire Department prepares a budget through a tra ditional budget process. The Controller prepares a rough draft of the budget with input from the City Managers of Belmont and San Carlos . Once this phase has been completed, a final draft budget document is prepared, reviewed, considered and adopted by the Fire Board at a public hearing. Finally, the Belmont Fire Protection District and City of San Carlos will ratify the budget adopted by the Board.

CITY COUNCIL
STAFF REPORT
MEETING DATE: June 10, 2024
ITEM TITLE: Adopt Ordinance 1615 Amending San Carlos Municipal Code Title 18 – Zoning, Section 18.15.120 (Underground Utilities) and Section
18.23.210 (Accessory Dwelling Units/Junior Accessory Dwelling Units) to Exempt Specific Single-Family Home Projects from the Requirement to Underground Utility Service Drops.
RECOMMENDATION:
The Planning and Transportation Commission (PTC) recommends that the City Council adopt Ordinance 1615 to exempt specific single-family home projects from the requirement to underground utility service drops.
FISCAL IMPLICATIONS:
There is no fiscal impact and no additional appropriation is needed at this time.
BACKGROUND:
During the City Council’s review of the objective design standards for single-family development at its October 2023 meeting, councilmembers expressed concern regarding the cost of undergrounding utilities for single-family home projects.
The PTC, at its April 15, 2024 meeting, reviewed the proposed amendment to the Zoning Code to exempt single-family homes, including ADU/JADUs and urban infill units (SB 9), from the requirement to underground utility service drops. Commissioners expressed concern that a property owner or developer could elect to construct a new utility pole in a neighborhood that is served by underground utilities. Staff noted that this would be a costly and unlikely scenario, however, the Commission elected to include language to clarify that the exemption would not apply to a new single-family home if the surrounding homes are served by underground utilities.
The PTC adopted a Resolution (4 in favor, 1 opposed) recommending that the City Council adopt the proposed Zoning Code amendments, with a recommended modification.
ANALYSIS:
During the May 13, 2024 meeting, the City Council introduced an alternate ordinance which would retroactively remove the requirement for specific single-family home projects, which have already been issued a building permit but have yet to receive the Certificate of Occupancy to underground the utility service drop.
Environmental Determination. This project has been determined to be exempt from the provisions of the California Environmental Quality Act (CEQA) Guidelines Section 15061(b)(3),
8.o

Packet Pg. 413
the general exemption for projects with no potential for a significant effect in the environment. As a text amendment, it can be seen with certainty that there is no possibility that the amendments will have a significant effect on the environment.
Next Steps. Should the City Council adopt Ordinance 1615 at its June 10, 2024 regular meeting, the proposed amendments would become effective on July 9, 2024.
ALTERNATIVES:
The alternatives available to the City Council include:
1. Adopt Ordinance 1615 to amend San Carlos Municipal Code Title 18 – Zoning: Section
18.15.120 (Underground Utilities) and Section 18.23.210 (Accessory dwelling units/junior accessory dwelling units); or
2. Do not adopt Ordinance 1615; or
3. Provide staff with alternative direction.

WHEREAS, the Ordinance shall apply to projects that have been submitted and to those which have been issued building permits, but have not yet received a Certificate of Occupancy; and
WHEREAS, the City Council finds the Ordinance update process evaluated the current issues with the existing ordinance and explored options for changes based on evidence and best practices in other communities and industry experts; and SECTION 2: The City Council makes the following findings:
A. The proposed ordinance amendments are consistent with the General Plan.
The recently updated 2023-2031 Housing Element includes the following goal:
•Goal HOU-4 which states: “Remove or mitigate governmental constraints inhibiting the provision of adequate, affordable housing throughout San Carlos.” Basis for Finding: The proposed ordinance amendments would remove a major financial burden and reduce overall project timelines for projects involving single family homes including ADUs and Urban Infill Units, which ultimately reduce cost and facilitate the faster generation of housing.
B. The ordinance amendment is consistent with the purpose of the zoning title to promote the growth of the City in an orderly manner and to promote and protect the public health, safety, peace, comfort and general welfare.
Basis for Finding: The proposed ordinance amendments promote further growth of single-family home projects in the city by removing a major financial burden and reduce overall project timelines for projects involving single family homes including ADUs and Urban Infill Units, which ultimately reduce cost and facilitate the faster generation of housing which is created in an orderly manner.
NOW, THEREFORE BE IT RESOLVED by the City Council of the City of San Carlos as follows:
SECTION 3: The City Council hereby approves the Municipal Code Ordinance amendment attached as Exhibit A.
SECTION 4: Replacement of Code. San Carlos Municipal Code Section 18.15.120 (Underground utilities) and 18.23.210(H) (Accessory dwelling units/junior accessory dwelling units) is hereby replaced with the language in Exhibit A.

the ordinance becomes effective.
SECTION 6: California Environmental Quality Act Determination. The City Council hereby finds that this Ordinance is exempt from the provisions of the California Environmental Quality Act (CEQA) Guidelines Section 15061(b)(3), the general exemption for projects with no potential for a significant effect in the environment.

CITY COUNCIL
STAFF REPORT
MEETING DATE: June 10, 2024
ITEM TITLE: Consideration of Adopting a Resolution Endorsing the Downtown Advisory Committee’s Recommended Street Design as part of the Downtown Specific Plan + Streetscape Master Plan Project and Direct Staff to Proceed with Technical Analysis.
RECOMMENDATION:
Adopt a Resolution endorsing the Downtown Advisory Committee’s recommended street design as part of the Downtown Specific Plan + Streetscape Master Plan Project and direct staff to proceed with technical analysis.
FISCAL IMPLICATIONS:
There are no fiscal impacts associated with receiving a presentation and adopting the Resolution endorsing a street design to allow the project to move forward with technical analysis. Funding for this project (C2105) – Downtown Planning Initiative (Specific Plan) has been previously appropriated. Although the preparation of the Downtown Specific Plan + Streetscape Master Plan is fully funded, financing for the construction of future street improvements has not been established at this time.
BACKGROUND:
Item Purpose
The goal of this item is to present the DTAC’s recommended street design to the City Council with a request that the Council adopt a Resolution endorsing the DTAC’s recommended street design and directing staff to proceed with traffic and parking analysis. This is not a final decision on the street design, but rather a firm commitment to proceed with the direction of the street design in its current configuration for further testing and modeling. Once the testing and modeling analyses are completed, staff will return to the Council to review the outcomes and tradeoffs before proceeding with further work and continued drafting of the Specific Plan + Streetscape Master Plan in preparation for adoption in 2025.
City Council Strategic Objective
“The City of San Carlos will work with residents, property owners, business owners, committees, commissions, the Chamber of Commerce, and all other interested members of the community to develop a plan to understand and ensure that the downtown meets the needs of the community and businesses now and into the future.”
Downtown Specific Plan + Streetscape Master Plan Study Area The Downtown Specific Plan + Streetscape Master Plan Study Area (Figure 1) is framed by Holly Street to the north and Greenwood Avenue to the south, with El Camino Real to the east and
9.b
June 10, 2024
Packet Pg. 424
Walnut Street to the west. The Downtown Specific Plan + Streetscape Master Plan will also address the streets around the Civic Center: San Carlos Avenue, Cherry Street, Elm Street, and Chestnut Street as indicated by the green dotted line in Figure 1 below.
Figure 1. Downtown Specific Plan + Streetscape Master Plan Study Area Milestones Since the Council’s last Study Session on the Downtown Specific Plan During a Study Session on April 24, 2023, the City Council confirmed its support to transform the 700 block of Laurel Street into a permanent public plaza. Four months later, on August 28, 2023, the City Council adopted Resolution No. 2023-108 to establish a pedestrian mall on the 700 block of Laurel Street. Shortly thereafter, staff met with downtown property and business owners, and the project team collaborated to refine ideas for a new public plaza plus additional street designs for the remainder of the downtown plan area.
A workshop with the Downtown Advisory Committee (“DTAC”) was held in November 2023 to gather their feedback on the refined ideas. This was followed by Downtown Ideation Workshops and Open House with the community, an online survey, and input from City commissions, which altogether led to a DTAC recommended street design on March 19, 2024. The Planning and Transportation Commission reviewed and provided input on the DTAC’s recommendation on May 20, 2024 (Attachment 2) and it is now ready to be presented to the City Council.
Civic Engagement and Public Comments
The civic engagement process for Downtown Specific Plan + Streetscape Master Plan executed a robust strategy to bring people together. This strategy included working closely with the City Council appointed DTAC and inviting input and feedback from the community at large. Working with the community, City staff invited participants to share their stories, concerns, ideas, and inspiration for what the future of downtown could be. Participants walked away with a better understanding that they can positively influence the quality, character, vibrancy, and health of the downtown where they live, work, and enjoy their time.
Since the beginning of this project, staff worked closely with the City’s Communications Division to carve out a process that would be inclusive and widespread. Outreach methods are listed in Table 1 below.

As part of the community engagement strategy, the planning process sought and continues to engage many key audiences through varied platforms to receive input; these are identified in Attachment 11, Civic Engagement Summary to Date.
ANALYSIS:
Vision and Guiding Principles
The evolution of the designs for streets and plazas were based on a shared Vision for Downtown and Guiding Principles. These were developed by the DTAC and refined based on communitywide feedback received during the Downtown Ideation Workshops and Open House and accompanying online survey. The Vision for Downtown San Carlos reads:
Figure
3. 1 www.sancarlosdowntownplan.com
“Downtown is the heart of San Carlos that provides a vibrant, pedestrian-friendly, safe, charming, futuristic, and accessible destination for the community. It is a place for celebration and gathering that offers diverse and authentic experiences through a draw of food, retail, services, art and music in a visually attractive environment for the growing community. Downtown is an inclusive place with easy access for all, opportunities for housing and businesses of all types, and inviting spaces for all users. Downtown San Carlos is a sustainable district, with landscape that supports ecological and community health and well-being.”

Figure 2. Concept Alternatives for the 700 Block of Laurel Street, Between Cherry and Olive Streets These ideas above were then further refined based on the communitywide feedback received during the Downtown Ideation Workshops and accompanying online survey.
Additional refinements were also developed from input from the City of San Carlos’ Economic Development Advisory Commission; Parks, Recreation and Culture Commission; and the Youth Advisory Council. For a detailed account of input and feedback received, please see:
•Attachment 4: Downtown Ideation – Community Feedback Summary Dec 6 and 9, 2023 •Attachment 5: Online Survey, December 26, 2023 through January 22, 2024 •Attachment 6: Economic Development Advisory Commission Input, January 23, 2024 •Attachment 7: Parks, Recreation & Culture Commission Input, February 13, 2024 •Attachment 8: Youth Advisory Council Input, March 13, 2024 Staff and the consultant team thoughtfully considered how to conceptualize all the input and feedback into a proposed design for the streets within the downtown core. This also included considerations from citywide staff that were gathered during an interdepartmental meeting on February 29, 2024. The street designs were then brought to the DTAC on March 19, 2024 for their consideration. The DTAC considered a comprehensive design for the 600, 700, and 800 blocks of Laurel Street as shown in Figure 4 below.

•Emergency vehicle access provisions
•Passenger pick up and drop off (PUDO) locations
•Retractable bollards for access and programmatic closures •Provisions/space for public restrooms and drinking fountains •Design that would accommodate all existing program offerings (e.g. Farmers’ Market, Art & Wine Festival, Goblin Walk, Hometown Days, Night of Holiday Lights, etc.)

The DTAC also gave clear direction to the project team to further study the following topics:
•Public Space Design: public plaza and the Harrington Park design elements •Mobility and Street Design: all the streets in the project area •Parking Strategy: on-street and off-street parking
•Alley Strategy: integration of alleys into the public space design •Programming: temporary and permanent programs to activate public spaces •Strategies for Businesses: policy changes for thriving businesses For a detailed account of the DTAC’s input from their March 19, 2024 meeting see Attachment 3.
Following the DTAC’s endorsement, the project team met with the City’s Parks, Fire, and Public Works Departments, the City Council Downtown Subcommittee, as well as members of the Silicon Valley Bicycle Coalition and staff from SamTrans. City departments were supportive of the proposed street design concepts and offered additional details and key considerations for the project team to address as the plan progresses. The Silicon Valley Bicycle Coalition and SamTrans were generally supportive of the proposed street designs.
Public Input Since DTACs Recommendation on March 19, 2024 The City received an email from the Silicon Valley Bicycle Coalition, in support of the street designs. The City also received an email from Peter Hartzel. See Attachment 10.
Next Steps
Should the City Council adopt the Resolution endorsing the DTAC’s recommended street design, the project team will proceed with technical analysis to test traffic and parking outcomes and tradeoffs. This analysis will be brought back to the full City Council for consideration to moving forward with the endorsed street design and continue drafting the Downtown Specific Plan + Streetscape Master Plan in preparation for adoption in 2025.
ALTERNATIVES:
The options available to the City Council include:
1. Adopt a Resolution endorsing the Downtown Advisory Committee’s recommended street design and direct staff to proceed with technical analysis; or
2. Do not adopt the Resolution; or
3. Provide staff with alternative direction.

Commissioner Comments
Vice Chair Clements inquired about feedback from businesses utilizing outdoor spaces.
She also asked if the City would consider charging for the use of these areas.
Commissioner Castaneda inquired about the proposed plan for El Camino Real. She observed that there are no bicyclists on El Camino and asked if there are safety concerns when cars from nearby cities encounter bicyclists. She also noted that other cities have parking along El Camino and suggested that San Carlos should implement this as well.
Commissioner Roof recommended investing in the Arroyo underpass to transform it into an inviting gateway to the biotech area. He also emphasized the importance of planning and gathering community input on the phasing of the construction to protect the businesses.
Vice Chair Clements encouraged the City to think about 10-minute parking spots as online delivery is more prevalent. She also encouraged the City to think about handicap parking spots and accessibility.
Vice Chair Clements encouraged the City Council to consider the impact of small business interruptions and transition costs, as some businesses may struggle to afford the changes required by the new design. She also emphasized the importance of supporting and fostering unique small businesses.
Commissioner Castaneda stated that she looks forward to receiving more information on traffic patterns as lane reductions continue.
Chair Iacoponi recommended developing the alleyway concepts sooner rather than later.

2 Downtown Technical Advisory Committee (DTAC) Meeting
03/19/2024 | 5:30 pm | San Carlos Adult Community Center • Trash Management: Policy and infrastructural recommendations. • Phasing and Implementation Plan
Public Space Design
o The committee favored the idea of curb-less street design for 600, 700, and 800 blocks on Laurel street. o Groves as a design element was appreciated with a suggestion to further investigate their location and placement, especially to make sure they are not affecting the visibility of businesses. o The committee recommended that the 700-Block of Laurel Street be a “wheel-free zone”, citing concerns around the safety of pedestrians especially that of seniors. o The committee emphasized considering accessibility in all public space design elements. o The committee advised that the project team also consider the reconfiguration of the side streets and intersections and not just the main streets in the specific plan area. o The committee recommended engaging with the stakeholders including Bianchini’s market for temporary use of their parking lot as a festival overflow space.
o The following design elements were suggested by the committee to include in the public space design:
• Raingardens.
• Water Fountain.
• Accessible seating/ furniture.
• Streetlights design reflecting the “San Carlos” character. • Uniform design for awnings and signage.
• Outdoor dining – while also providing enough walking spaces on the sidewalk. • Tree species responding to local ecology (trees and their surroundings need to be better maintained)
Mobility and Street Design
o The committee mentioned the following circulation challenges:
• The current configuration of San Carlos creates traffic congestion and blockage, and the road diet will intensify the traffic congestion issues.
• The turnings on Cherry Street are dangerous and need design interventions for the safety of all users.
• Walnut Street is a difficult street to maneuver and needs signals at specific intersections. • The circulation on Cherry and Walnut Street is often blocked off by delivery trucks, food delivery services, and double-parked vehicles, creating challenges for the residents. o The committee suggested calling the alleyways as “Passageways” and be made part of the circulation network.
Parking Strategy
o The committee identified parallel parking on 600 and 800 blocks of Laurel Street as a concern, as it causes traffic flow to slow down and create a traffic back-up. o Considering the reduction of on-street parking spaces on Laurel Street, the committee suggested exploring a strategy to phase out the removal and relocation of parking spaces.

3 Downtown Technical Advisory Committee (DTAC) Meeting
03/19/2024 | 5:30 pm | San Carlos Adult Community Center o The committee asked to consider access and safety in the off-street parking lots, especially for employees working late hours..
o The committee suggested studying the possibility of having a parking garage, perhaps with the acquisition of a parcel to build one, in the Specific Plan Area.
o On Laurel street at the Post Office, the committee suggested that the on -street parking adjacent to the Post Office needs sufficient, at least the same as existing, number of parking spaces. o The current configuration on San Carlos Avenue has diagonal parking. The committee suggested developing a parking layout different from a diagonal parking arrangement.
Alleys Strategy
o The committee suggested focusing on the 700-block alley, considering its complex circulation and access needs involving delivery trucks, trailers, trash, and parking. o The committee stressed the need to introduce the parking assessment district on both sides of the 700 block.
o The following considerations were recommended for design of the alleys. • Function and beautification.
• Safety.
• Indicators/ signage for parking availability.
Programming
o The committee mentioned that downtown San Carlos is overextended to the restaurants and needs to consider other active uses and programs to activate its public realm. o While the Harrington Park programming was supported, the committee was divided on the proposed level changes in the park. Some preferred it to be sunken while others preferred it to be at one grade, even with the sidewalks.
o The following programs and uses were suggested by the committee:
• Public Restrooms.
• Outdoor Dining.
• Public Art – either as soft elements as surprise features during the walk or contextual themes - based murals, etc.
• Designated pick-and-drop spaces.
• Ice skating rink during winter season and roller-skating rink during summer season.
Strategy for Businesses
o The committee advised the project team to develop strategies to retain the businesses in the downtown. o Citing the formula business ordinance of the City of San Carlos, the committee suggested that the city needs to carefully review the ordinance and seek opportunities to introduce at least one anchor business/store in the Downtown to make it a regional destination. o The committee preferred the wide sidewalks and walkable environment around the businesses but suggested that they be supported with on-street parking.

4 Downtown Technical Advisory Committee (DTAC) Meeting
03/19/2024 | 5:30 pm | San Carlos Adult Community Center Trash Management
o The committee suggested regulation of the trash pick-up and delivery times. o The committee recommended that the policy for trash consider pick -up services to access the trash in the existing enclosures. Additionally, it was advised that the proposed trash enclosures should be designed for ease in loading and unloading of trash bins.
o As per the committee, trash management is an important component that the specific plan should incorporate.
Phasing and implementation
o From the phasing point of view, the committee suggested that to take pressure off Laurel Street while it undergoes changes and to ensure access to businesses during construction, alleys should be improved first and made available for effective use.
o The committee highlighted the 700-block alley and its access ways as the first phase to prioritize improvements.
o The committee suggested that the project team develop a timeline for construction including phasing strategies.

• Concerns about traffic flow and lighting, especially for pedestrian safety. • A couple of people expressed that retail stores in downtown San Carlos are expensive and there is not enough diversity of products available. So, while they would like to support local businesses, they don’t end up shopping as much downtown. • One of the downtown business owners expressed concerns about how frequently the 600 block gets closed for events. With permanent closure of the 700 block, they expect that the city would leverage the 700 block as a venue for events and festivals and minimize closure of other blocks so that it doesn’t impact the businesses there.

‘Other’ responses:
1. Parking and service. Why is an alley, a rare commodity in the Bay Area, being used like this? Widen the sidewalks on Laurel St, remove some parking there, activate the front of businesses and major corridors.
2. I will add, what was the original plan for the stage at Harrington Park? Has that space been utilized fully to its original concept? Originally (before COVID) T own had a bump-out. It worked. Go back to that plan.
Hallmark store has no convenient shopping because people want to eat outside. People with mobility issues are being overlooked. Parking is limited and inconvenient for handicap placard users. A friend using walker can’t get to beer place next to T own. Handicap drop off isn’t as easy as people think.
3. More trees
4. Night club
5. Covered shelter space for residents to reserve for private parties, family friendly.
6. No Ugly Orange Barricades
7. I do not support the closing of streets
8. Don’t change it
9. Go back to laurel street pre-Covid
10. Open Street
11. Gathering space
12. Zero Waste collection bins
13. WIFI
14. Parking (need to be age friendly - we have a large older adult population) also fruit trees
15. Parking for older adults
16. Reopen the street. This block has the most parking spots in town including Handicapped spaces
17. Access for people with disabilities; improved and upgraded pavement/ hardscape; increased and clear signage; possibly more security measures due to less activity after business hours; consider shuttles from
locations such as senior center, train station for less mobile residents who can’t park adjacent to downtown; potential increased parking in underutilized infill areas such as Caltrain right of way, etc
18. More Adult bars/entertainment

Question 11
Responses
Recurring Themes:
• Parking availability and restrictions
• Traffic flow and road layout
• Street greening and tree planting
• Outdoor dining and seating areas
• Bike lanes and pedestrian spaces
1. 64' curb to curb
2. No!
3. Road diet. 4 Lanes of travel creates big natural barrier.
4. Any amount of increased street greening, outdoor seating/dining, more space for pedestrians and alleyway parking?), That would be ideal. Perhaps parking on the 2 blocks could be limited to 20-30 minutes only to support the businesses with a majority of spots for handicapped?
5. Parklets need to be more attractive from the street, look less like tent encamp- ment. More street trees.
6. Sidewalks with dining
7. Street greening. More trees do not use car lane for bike lane
8. Existing- no way one car lane will be adequate
9. Outdoor seating, more greenery
10. Maximize space for people. Cars should be secondary
11. Neither, get rid of the auto-oriented center turn lane/ median and give that back to pedestrians and bikes. Alternatively, use the median for parking like w.
Lancaster blvd in lancaster, ca.
12. Difficult to see on a phone. Keep it the way it is.
13. Less cars, more trees, more square-shaped space for connecting with other people. Space for
14. Looks great! I love the addition of the bike lane to this street.
15. Dedicated bike lines.
16. There’s only 1 choice here.
17. Restrooms
18. Do not change anything, it works as is.
19. Like proposed
20. The proposed changes appear to reduce san carlos ave to one lane of vehicle travel each way. This is a major artery traveling east toward el camino and should have two lanes traveling east. Since only one lane of traffic from el camino can turn onto san carlos at a time, perhaps only one travel lane is necessary
westbound on san carlos ave from el camino, but two lanes (or one lane plus a dedicated left turn lane) should be available going west whenever a left turn is possible (so left turning traffic does not impede thru-traffic.)
25. Street greening, less street parking
26. More division between car lanes and outdoor eating areas.
27. Parklets, outdoor dining and parking
28. Turn lane optiones, for sure!
29. The more trees, greenway, and parks the better.
30. I like the proposed plan, with the separate bike lane and a wider sidewalk for outdoor dining.
31. Option 2
32. Given the access to the west side of sc leave existing
33. Outdoor seating and more trees
34. Proposed scheme subject to traffic study for lane reduction Question 12
1. Proposed is better
2. 76 curb T o curb
3. No!
4. Road diet southbound. Wider sidewalks.
5. It seems ideal to shrink ecr down to 2 travel lanes for a short dis- tance around the downtown of sc. Wondering if it will just make an already crowded travel route more of a road rage? Is there a way to buffer the town from ecr by “thicker” buffering? I like the idea of no parking along ecr for a specified range and increasing the safety of the parking on the east side of ecr.
6. More street trees on both sides and in center median. Parking is needed.
7. Why are trees bigger in the proposed visions? Lol. More trees every-where, please.
8. Safer (wider?) Pedestrian walk zone from caltrain
9. More walkability would be great
11. Existing
12. Strongly prefer proposed scheme with fewer travel lanes and larger trees to better coordinate with traffic lanes in belmont and redwood city
13. No comment as i am not clear from the diagrams.
14. Medians, fewer traffic lanes. Greening
15. Way more space for trees so they can grow large and healthy to help with scale, parking buffered bike lanes, skinny median like wilshire blvd in santa monica, less travel lanes to induce congestion and slow traffic for increased pedestrian and bike safety.
16. Difficult to see on a phone. Keep it the way it is.
17. I like laurel to be hidden from el camino traffic
18. Great!
19. Sidewalk pedestrian access
20. Dedicated bike lines would be preferred.
21. There’s only one idea here.
22. Street greening
23. Available parking
24. The proposal pictured here is not detailed enough to make an educated
25. decision because el camino at san carlos ave and el camino one block away at holly are very different due to holly being the main artery in/out of downtown.

Question 13
1. 2 lane
2. Stop messing with my town!
3. Wide multi-use path looks great.
4. I would support the changes to Arroyo over the Brittan Ave changes since Britain is more of a major thoroughfare than Arroyo. For access to Britain Park, Arroyo can be used and the park accessed by better bike and pedestrian safety along Cedar Street & Elm Street.
5. More trees and consideration for bicycles
6. New
7. Seems ok
8. Left turn lanes
9. Yes
10. You’ll never get away with 22’ curb to curb because of the fire department wanting 13’ lanes for their huge trucks and outriggers. 12’ with trees, building entries and street furnishings (lights, transform-ers, utility cabinets, etc.) isn’t enough space
11. A bike boulevard is a great idea.
12. Like it!
13. No Speed deterrents on Holly
14. Make the entire downtown more pedestrian friendly. Promote walking around the downtown area. Less reliant on cars.
15. Ped and bike lanes need to be separated
16. Having bicycle boulevards would be a plus
17. I like the idea of adding bike lanes but would this mean no one can park on the street? We still need places to park.
18. Traffic mitigation, traffic lights to safeguard pedestrians
19. 22 ft curb to curb

Recurring Themes:
• Bike and Pedestrian Infrastructure and Safety
• Preservation of Vehicular Traffic Flow and Access
• Environmental Enhancements and Tree Planting
• Support for Multi-use Paths and Walkability
• Concerns Over Parking Availability and Management
20. Do not change anything, it works as is.
21. Proposed
22. Existing
23. As with El Camino near Holly/San Carlos Ave, Brittan Ave is the other major artery in/out of downtown, so I think care should be taken to allow for current or future increased vehicular traffic volume (since population/ housing is expected to increase, vehicular traffic likely to increase).
Therefore, I think it makes sense to add the pedestrian/bike/multi-use path along Arroyo, but not Brittan if the changes to Brittan would restrict vehicular traffic flow.
24. existing is fine
25. Trees dividing travel and multi-use lane is good. Bushes or large planters could also be nice. Trees in an oversized elevated planter could be nice too.
Would give more weight and substance to the division between travel lanes and multi-use lane. Separating bike lane from walking lane with bollards is also great. Would probably need some sidewalk markings to make sure which side is pedestrian vs wheeled. The bollard is especially important if allowing e-scooters or e-bikes in multi-use lane. Would need to establish guidelines as to whether motorized non-car wheeled transportation is allowed or just human powered bikes, skateboards, or push scooters
26. Wider sidewalk
27. Looks good
28. no
29. Yes
30. More walkability would be great
31. Yes
32. No, make quieter side streets into bike blvds
33. The bike lanes with physical separation are welcome. Could one bike lane with bikes in both directions work?
Question 14

1. Let’s make San Carlos a forested city! With native trees like oaks, redwoods, madrones, manzanita much nicer hanging flower baskets.
2. Please find a place for a community pool! This is what our town desperately needs.
3. Seems like the team is missing an opportunity to better link the Caltrain station to downtown.

5. Thank you for your work.
6. Thank you for all of the time spent on this project. Beautiful ideas!
7. Reduce speeds on holly.
8. Make it really pedestrian friendly. Promote walking around town.
9. Sticky saps from the trees need to be addressed. The current diseased tree makes pavement sticky.
10. Laurel Street is definitely the heart of San Carlos. Many towns do not have space like this.
11. Quit ruining everything. Keep things the same.
12. I like the idea of more European pedestrian area. Limit kid focused on laurel.
13. Besides downtown: safe walking streets on Brittan W of Alameda are needed.
14. I’m thinking you would be well to find out what other cities have done and visit them for ideas.
15. Cobblestones section with illuminated tiles with inspirational wording like Place du Molard in Geneva, CH.
16. Improve design standards and reduce the length of parklets. Outdoor eating, not covered shacks.
17. The downtown should primarily provide for the daily needs of the community.
18. Consider ample and attractive street lamps consistent from 600-800.
19. No further comments.
20. Please consider all ages/stages. Thank you!
21. All things pedestrian friendly please! No need to cater to our car culture. •

Preservation and enhancement of greenery (more trees and parks) •
Community-oriented spaces (including a community pool and places for all ages)

Traffic and parking management
•
Maintaining the small-town vibe and character Inclusive planning for all ages and abilities

Art and culture (activating alleys, avoiding big events that could be disruptive)
Enforcing existing traffic and vehicle laws
42. San Carlos is a family town, keep it welcoming for all ages! Plants, trees, and more seating.
43. If a water feature is installed make sure it uses a water pump that doesn’t drain and waste water.
44. The magic of San Carlos is the community. Optimize downtown for regular community events.
45. Let’s also make this a place where the youth feels welcome 12-18.
22. Activate the alleys so they specialize in art or antiques and change delivery to 2:00 AM.
23. More trees, the better.
24. Great vision, thank you! Arroyo Ave should connect to cedar street, which needs protected bike lanes.
25. Please no concerts or big events that trash our beautiful city.
26. Those huge orange dividers are awful.
27. It would be great to have multiple places for people of all ages/abilities could go and “hang out”.
28. Night club.
29. Lived in SC for years and miss the small town vibe. Nostalgic for independent stores, shops, and res.
30. Please consider an ordinance restricting overnight parking in San Carlos like Menlo Park.
31. I don’t care for street closures. For bike lanes, strict enforcement of vehicle laws.
32. Worldwide downtown areas are designed for people. Outside dining, young adults, people. Interfacing.
33. Thank you for asking!
34. More kid-friendly mini playgrounds.
35. All restaurant owners should pay market rate for expanded outdoor seating.
36. Close Laurel to traffic, increase service shopping for locals.
37. It’s not a shopping mall. It should look and act like a walkable treed urban space.
38. I would like to see cafe seating on the main walkway and enjoy people watching.
39. Shuttle to eliminate traffic/parking for those that do not live within walking distance, and seniors.
40. Whatever is done downtown, please enforce the traffic laws better than they are enforced at this ti.
41. I loved how the vision statement made accessibility such a prominent point.

Questions and Answers for DTSP Team:
Jule Lubetkin
1. Are we getting rid of parklets? Where will dining go? o WRT Response: Yes, parklets will be gone. Dining will have more flexibility on 700 block and on others, it will be against the buildings.
2. L along San Carlos Ave- is there any more detail on San Carlos Ave? o WRT Response: We have studied a revised cross-section for SC Ave. It eliminates one lane in each direction and additional turn lane for left turners . Multiuse curb lane will be added and will be wider - deliveries/drop off/bikeshare/ lots of different activities are competing and those uses could change as demand changes.
3. Parking lots btw ECR and Laurel are chaotic.. Are they included? o WRT Response: Yes they are included and its being studied right now. We will show these designs in future. We will look into how to better organize those parking lots, so they are legible and better accessible, greener with tree islands, have better paving and better lighting.
Cecile Lee
1. Pets are part of community - are there any ideas like water features for dogs or areas for dogs to be more social or an activity for dogs?
a. WRT Response: We did hear comments to make Downtown more dog-friendly. Please share ideas on what will make your pet happiest in downtown.
2. As we get more popular and there are more events people visit. What about a disaster plan for people to understand in case of stampede and emergency situations? a. WRT Response: Emergency evacuation and planning is something we need to think about. We have a meeting with fire department coming up where we will dive into this.
3. Hesitant to use Samtrans parking structure.
a. WRT Response: We are identifying that as a resource and working with a consultant to come up with options.
Mark Maxwell
1. Will we be rerouting parades?
o WRT Response: Annual hometown days parade (it’s a car parade) - in our mind, we will think about rerouting parade.
• Space has to accommodate fire engines
• Pavement will need to hold fire engines (in terms of weight) o Tyler's Response
• To provide more context on booths. For art and wine they were back to back and we changed them due to fire access and they were moved of curb. It did limit number of booths we could add. Businesses don’t like booths being against their store and block access to their storefront. So there's pro and cons to both. • Block on San Carlos Ave going to ECR. We don’t put booths there because you get stuck at dead end at ECR. There's a median there with a gate structure to it.

Bob
1. Will landscaping continue down to Eaton?
a. We are doing a streetscape plan and want to be comprehensive
John
1. Will we push back the storefront to make more space? o WRT Response: We will not put the existing one back but if you rebuild property, you will be subject to new setbacks.
• All parcels on ECR frontage have a lot of potential as redevelopment sites. There are some historic sites but by and large they are prime candidates for rezoning.
And new zoning allows them to be dense in terms of FAR.
2. What is the plan for Harrington Park - it already have a stage but never fully utilized. o WRT Response: Stage is used as seen in wine and art but landscaped areas get trampled.
It seems like it's a good use for the area but it needs to be setup.
3. Wheelers plaza - does it include blue line pizza?
o Plaza will be at current parking lot. We will come up with a better name as project evolves.
4. The alley behind 700. It needs help now. It's been closed for 3 yrs
5. How many parking spaces now and in future on 600 and 800? o Right now there are 20 - 22 in each block on 600 and 800 on Laurel on street. We are proposing is lesser than that but more public space with 12 - 15 in each block (it's a tradeoff to get more public space)
6. How cohesive does City want storefronts to be? Is that a goal? Does it take on a uniform look? o Lisa Response: In our ZO, the project needs to meet first floor including requirements for cohesive architecture. We are not like santa barbara to be overly prescriptive. Going back to placemaking and identity, there are some elements we want to look at as part of Specific Plan.
o WRT Response: Retail heights are important. That's design standard we want to ensure that we have nice and tall retail heights going to 15 to 20 feet, which would be consistent with what we have now.
7. How difficult would it be for properties to be redeveloped and keep it looking nice and consistent in terms of design once the new pedestrian plaza is in place? o Lisa Response: Our building division oversees redevelopment and looks at this such that if any of those plaza elements are disturbed, they can be restored.

urban design
framework to
the DTAC
GROUP 1
Facilitator: Rohit Tak
Notetaker: Akanksha Chopra
ACTIVITY 1: Review and Confirm the Draft Vision & Guiding Principles Keeping the small-town feel
Including “Pet Friendly Downtown”, in the vision statement; Downtown should be welcoming to people from all walks of life and backgrounds, for this, emphasis on inclusive and equitable strategies to revitalize downtown should be explored (since Peninsula has a reputation of being fancy and high profile); Character & identity – need to understand what we want, a local or regional destination; Plaza design – shall consider flexible programs and spaces, so it’s not specific to a purpose; Businesses – strategies for business growth with consideration of locally own businesses; El Camino Real – making it a mixed use corridor;
Mobility –
Strategies to minimize auto-trips are a must, we don’t want to drive to the downtown on daily basis;
Providing affordable EV charging.
ACTIVITY 2 - Discuss The Public Realm Concepts
o Character and identity
Need a consistent and harmonious style and feel
Something is needed that celebrates identity of everyone . Programs and spaces accommodating activities as Yoga, tai-chi, community yoga – so people from everywhere can join;

Fountain/Water feature of some kind is needed in the downtown to create some strong image;
Something unexpected/element of surprise;
Gateway elements at alley and parking entrances are encouraged. o Downtown Vibrancy
Diversity of businesses:
• We have a good mix of restaurants – how can we make them further diverse?;
• Restaurants act as a magnet for people;
• Many businesses are struggling to exist.
o Mobility & Connectivity
Public transportation “does not exist”;
There are no buses in neighborhoods anymore;
Shuttle pilot which the city implemented some years ago was a helpful to access downtown, between 4:00 – 8:00 PM, without driving cars, approaches like this are recommended;
If you are narrowing 600 block, please note that there is already a spillover in residential areas.
o Equity and Resilience
Local small shops are gone as landlords charge bay area rents; We have a regulations that have kept out big businesses, but due to that we may be missing on some good ones;
Cooling zones in summer;
Apart from climate resilience, earthquake resilient strategies should be included.

• Notetaker: Sajuti Haque
ACTIVITY 1: Review and Confirm the Draft Vision & Guiding Principles o Affordable EV charging - do we need the word affordable?; o If the City installs, do they have control over the costs?
ACTIVITY 2 - Discuss The Public Realm Concepts
o Character and identity
Preference of concept:
• Everyone prefers Concept 1 because it’s bolder and stronger because its consistent;
• Everyone really likes the water play;
• Perhaps we can add art installation like San Jose ;
How would the flow of seating work with tree lines;
• The whole thing can be curb less and there is enough space for the seating; The Union bank outlet- is that temporary or permanent?; Outdoor reading in front of the Reading Bug should keep going. o Downtown Vibrancy
Activation of uses: would that be broken down by ages?; Prior to 6:00 PM - it’s a very local space;
Not a lot of nightlife;
Question: what kind of downtown times do we want? That will dictate what kind of businesses we will attract?;

7:00 AM – 4:00 PM – errands time in the downtown;
Weekends- very different feel/ attracting folks from out of town; Questioning the need for gateways because its already so popular; Do we actually need anything in mid-Laurel?;
YAC member- consistent activities for youth is important:
• This project doesn’t cover the CalTrain Station plaza- but that’s a great place for movies or other free activities;
• EX: Hillsdale Shopping Center plaza;
List of Preferred Uses:
• Theatre;
• Non-paid seating with wi-fi;
• Skate park;
• Non-traditional benches/ sturdy;
• Bowling alley;
Indoor or Outdoor Recreational space such as Urban Putt; Concept 2 is too zig-zaggy; perhaps do that at a smaller scale in a sperate space; The current reality of Harrington park – there are a lot of homeless people currently because it’s narrow and dark; not well-lit;
If we get music at the park how will that impact the music at Faith and Spirits Piano Bar?;
Burton Park already meets the lawn need with the stage and community; Performances; in the downtown it would be better if it’s paved with seating rather than a lawn;
Does Harrington Park want to be an event space?;
Can we extend Harrington Park through the back into the alleyway towards Mama Coco?;
Have we confirmed that Wheeler Plaza is not going to be a parking lot and will be a plaza?;
Wheeler Plaza should be facing towards the alley;
For some programming- we can have cheaper food vendors/kiosks; • Urban Block- company takes shipping containers and builds them into restaurants;
• Keep things flexible to change as the needs change;
• Like a Food Hall like San Pedro Square Market;
• Have the goblin walk parade there;
• We want people to hangout without having to pay for things. o Mobility & Connectivity
Could we only keep the 700 block closed and not touch the other blocks?; • Staff heard that there is a lot of focus on the 700 block and other businesses on the adjacent blocks also want the benefits of being in the pedestrian zone; Circulation: is there a bigger plan to improve connectivity within the area?; • Response: we are looking into the circulation;
How will the businesses be impacted during all the DTSP improvement construction?;
• While closed for construction- let’s get the alleyways to be the entrances; They would like to see the street sections next to the uses to see which one works better;
Can we expand the 700 block into the 600 block without changing the current parking?;

GROUP 3
• Facilitator: James Stickley
• Notetaker: Ashwin Nambiar
ACTIVITY 1: Review and Confirm the Draft Vision & Guiding Principles o Emphasize equity and affordability within the community; o Higher rents leading to increased product prices;
o Review and potentially modify form-based codes;
o Consider seasonal variations in planning;
o Integrate events for both children and adults;
o Site next to Harrington Park as a potential housing element site;
ACTIVITY 2 - Discuss The Public Realm Concepts
o Character and identity
Consider alleys as “gateways” with better wayfinding; Assess why people may not be visiting downtown apart from specific restaurants; Should San Carlos aspire to become a dining destination;
o Downtown Vibrancy
Create a distinct identity and character for the downtown area, strong opinion on not becoming another Burlingame;
Prioritize activity-oriented spaces, such as an ice-skating rink, lasermax, a bowling alley, art- bias;
Develop a decentralized Youth Center along the 600-700-800 block or a “youth activity cluster”;
Centralize the location for the farmers' market booth to increase visibility and access to retail stores on the 600 block;
o Mobility & Connectivity
Analyze the implications of stiff parking fines, particularly in alleys, and its impact on employees;
Look into making alleys pedestrian-friendly, drawing inspiration from Burlingame; Develop Cherry Street as a pedestrian walkway from CalTrain parking lots; Focus on improving the flow of parking and overall circulation, especially in relation to the Caltrain parking lot;
Consider ease of pedestrian circulation from restaurants and beer gardens near the Caltrain station to San Carlos downtown by improved accessibility and safety for crossing El Camino Real;
Show parking and circulation in alleys in the diagrams;

Planning Commission and Staff,
Thank you very much for the open meeting on Monday, May 20th.
On reflection after the meeting I have two recommendations for the process outlined for the weeks and months ahead as the designs and implementation plan are finalized.
1. Think boldly about how to create a central feature in the 700 block of Laurel.
I am excited by the idea of permanently closing off the 700 block to traffic and using the Harrington Park axes for a central feature to the downtown. Upon reflection I encourage San Carlos to think boldly about how such a feature could add to the cohesion of downtown and become a draw in and of itself that reinforces the attractiveness of San Carlos, for residents and for visitors. Consider the great downtowns of Europe. Often they feature a fountain or statue or obelisk. In the best cases this becomes a meeting or gathering 5/30/24, 1 39 PM For CC packet public comments Linnet Kwok Outlook about blank 2/10

place. Around it often are chairs or tables or it is in itself a place to sit. Good examples are:
Piazza del Popolo in Rome
Trafalgar Square, London
The Chicago Bean

Arguably, San Carlos is not London or Rome or even Chicago.
However, no other peninsula city has such a feature in its downtown that is, in and of itself, an attraction to visitors. Stanford has the Old Union Fountain, White Fountain and clock tower which are examples of features.

In San Carlos, I suggest the designers consider:
a. Something on the scale of the Old Union Fountain, although with an oval base versus a square to correspond with the space and linear lines of the street.
b. Raising it off the grade level to provide focus and attention and allow seating at/on the base and (as mentioned in the presentation) at public cafe tables around its base.
c. It expressing and organic nature. This is to correspond with our times -- organic, natural, respect for our environment -- as well as to connect with the tree-inspired street names of our downtown.
Here are some examples to consider/inspire:
Wouldn't it be wonderful to have a tree with expressive personality and seasonal changes with bright green leaves in the spring and empty branches in the winter?

Or, given that the street is named "Laurel" a native Bay Laurel tree.
The designs shared in your meeting included ideas for new trees and lighting. Maybe it is possible to simulate the feeling of the waving trunks of a Bay Laurel forest through the design of the light fixtures and trees along the 700 block. A mature Bay Laurel could also be
the feature ... there are some wonderful inspiring examples in Pulgas Ridge and along the Sawyer Camp Trail.
Or, if the maintenance of a signature tree is deemed
challenging, a sculpture with organic properties and on the scale of a tree is an option.

2. Include in the plan improved aesthetics in alleys that run between and behind Laurel and El Camino.
The design proposal was mainly focused on Laurel St. itself with traffic routing, widening sidewalks, accommodating bicycles, new tree plantings, parallel vs. angle parking, etc.. However, the larger concept was to make a cohesive downtown area
including the alleys running parallel to Laurel and out to El Camino. It is my experience that the El Camino retail stores are isolated from downtown. It is hard to park in front of them and they have no presence facing the alley between them and Laurel Street. An exception is Mints and Honey (and to a lesser degree Plantation Coffee or Gourmet Haus Staudt/Beer Garden on Broadway in RWC) which has an entrance and
inviting signage on both its alley and El Camino sides. While ultimately, it seems it will be up to the building owners and retail stores to decide if and how to attract customers from their alley entrances, I encourage the city's design work to find ways to encourage this connectivity.
