circumstances.
3.5 PREPARATION OF TRENCH
A. Line and Grade for Main:
1. For pipelines intended to be straight, do not deviate more than 1/2 inch from line or 1/4 inch from grade, provided that finished pipeline will present a uniform bore, and such variation does not result in a level or reverse sloping invert, or less than minimum slope. Measure for grade at the pipe invert, not at the top of the pipe.
2. Grade the bottom of the trench by hand to the line and grade to which the pipe is to be laid, with proper allowance for pipe thickness and pipe base.
Remove hard spots that would prevent a uniform thickness of bedding.
Before laying each section of the pipe, check the grade with a straightedge and correct any irregularities found. The trench bottom shall form a continuous and uniform bearing and support for the pipe barrel between bell holes.
3. Bedding material under the pipe shall be compacted in 8-inch maximum lifts to the required minimum compacted required in Section 332315, "Excavation and Backfill." If, during pipe installation, a pipe section is found to be at an incorrect grade, the section shall be removed and the base regraded to the proper elevation.
B. Bell (Joint) Holes: At the location of each joint, dig bell (joint) holes of ample dimensions in the bottom of the trench and at the sides as required to permit the joint to be made properly, and to permit easy visual inspection of the entire joint and checking the gasket with a feeler gauge.
C. Removal of Water: The trench shall be kept dry until the pipe laying is completed and the pipe zone material is installed.
3.6 PREPARING PIPE FOR TRENCH
A. Inspect each pipe and fitting before the pipe and/or fitting is lowered into the trench.
B. Damaged portions of pipe, coating, or lining shall be cleaned and repaired by experienced personnel, so that the pipe is equal to the original. Manufacturer's recommendations for repairs shall be followed.
C. Wipe the joints of pipe, fittings, and appurtenances clean of all dirt, grease, and foreign matter before the pipe is lowered into trench.
D. Plug or close off pipes that are stubbed off for access structures (such as manholes) for connection by others with temporary, watertight plugs.

D. Prevent foreign material from entering the pipe while it is being placed in the trench. Remove all foreign material from the pipe and spigot area before the next pipe is placed. If the pipe laying crew cannot put the pipe into the trench and in place without getting earth into the pipe, the Engineer may require that snugly fitted, tightly woven, canvas bags be placed over each end before lowering the pipe. The bags shall be left in place until the connection is to be made to the adjacent pipe. During laying operations, keep debris, tools, clothing, or other materials out of the pipe.
E. Take all precautions necessary to prevent the "uplift" or floating of the line prior to completion of backfilling operations.
3.8 PERMISSIBLE DEFLECTION AT JOINTS
A. Deflection of pipe joints is not permitted without prior written approval of the Engineer. Where it is approved by the Engineer to deflect pipe from a straight line, either in the vertical or horizontal plane, do not exceed 50 percent of the amount of deflection recommended by the pipe or coupling manufacturer and as reviewed by the Engineer.
3.9 PIPE ZONE MATERIAL
A. Particular attention must be given to the area of the pipe zone from the flow line to the centerline of the pipe to ensure that firm support is obtained to prevent any lateral movement of the pipe during the final backfilling of the pipe zone.
3.10 STORM DRAIN CLEANING
A. Prior to final acceptance remove all accumulated construction debris, rocks, gravel, sand, silt, and other foreign material from the system at or near the closest downstream manhole. If necessary, use mechanical rodding or bucketing equipment. The Contractor shall provide CCTV reports and videotape depicting the condition of the newly installed pipe.

CITY COUNCIL
STAFF REPORT
MEETING DATE: August 12, 2024
ITEM TITLE: Adopt Ordinance 1618 Adopting a Zoning District Boundary Map Amendment to Allow Prezoning of the Property to RS3: Single Family, Low Density for the Property Located at 244 Club Drive (APN: 049- 050-070).
RECOMMENDATION:
Adopt Ordinance 1618 to amend the Zoning District Map to a zoning designation of RS-3: Single Family, Low Density (3 DU/Acre) to allow for the prezoning and annexation at 244 Club Drive, Assessor’s Parcel Number 049-050-070.
FISCAL IMPLICATIONS:
The costs to process the proposed annexation are paid for by the applicant. The Fiscal Impact Analysis (FIA) prepared by Economic & Planning Systems, Inc. (EPS) concludes the annual net fiscal impact of the annexation would be roughly neutral. No additional appropriation is needed at this time.
BACKGROUND:
During the June 24, 2024 City Council meeting, the Council introduced the ordinance to amend the Zoning District Map to facilitate the prezoning and annexation of one developed, single-family parcel at 244 Club Drive. The Council also adopted resolutions for a General Plan Map Amendment and to authorize a property tax exchange between the City and County of San Mateo.
The Planning and Transportation Commission previously conducted a public hearing on April 1, 2024 and adopted two resolutions recommending City Council approval of a General Plan Map Amendment and a Zoning District Boundary Map Amendment.
ANALYSIS:
The project site at 244 Club Drive contains one developed parcel that is located in the County of San Mateo adjacent to the City’s northwestern boundary. While not within the City jurisdictional boundary, the site is located within the Local Agency Formation Commission (LAFCo) adopted Sphere of Influence (SOI) of San Carlos. The City is required to process applications for annexation within its SOI. If the application meets the City’s General Plan policies and is within the City’s SOI as outlined by LAFCo for annexation, the property could be prezoned for annexation.

Zoning District Boundary Map Amendment
Chapter 18.38 “Prezoning and Annexation Procedure” of the Zoning Ordinance outlines the procedure for prezoning and criteria for annexation of unincorporated territory. Further, the Zoning Ordinance specifies that such requests shall be processed in accordance with the procedures of Chapter 18.35 “Amendments to the Zoning Ordinance and Map”. An analysis of the project’s ability to comply with both the Zoning District Boundary Map Amendment findings and criteria established in the Prezoning and Annexation Ordinance is required. The findings recommended by the Planning and Transportation Commission are embedded in the Ordinance of the City Council (Attachment 1).
Environmental Determination
This project has been determined to be exempt from the provisions of the California Environmental Quality Act (CEQA) per Section 15319 Annexation of Existing Facilities and Lots for Exempt Facilities and Section 15303 New Construction or Conversion of Small Structures.
Next Steps
Should the City Council adopt Ordinance 1615 at its August 12, 2024 regular meeting, the proposed amendment would become effective on September 11, 2024.
ALTERNATIVES:
The alternatives available to the City Council include:
1. Adopt Ordinance 1618 to amend the Zoning District Boundary Map to RS-3: Single Family, Low Density to allow for the prezoning and annexation of the property located at 244 Club Drive (APN: 049-050-070); or
2. Do not adopt Ordinance 1618; or
3. Provide staff with alternative direction.

WHEREAS, it is determined that the aforementioned property is located within the Local Agency Formation Commission (LAFCo) adopted sphere of influence (SOI) of San Carlos; and WHEREAS, in accordance with the California Environmental Quality Act (CEQA), the City Council has determined that the application for a General Plan Map Amendment and associated Zoning District Boundary (Map) Amendment for the aforementioned properties is exempt from the provisions of CEQA pursuant to Section 15319 Annexation of Existing Facilities and Lots for Exempt Facilities and Section 15303 New Construction or Conversion of Small Structures; and WHEREAS, on April 1, 2024 the San Carlos Planning and Transportation Commission (PTC) conducted a public hearing for consideration of a Zoning District Boundary Map Amendment and Prezoning and Annexation for the aforementioned property to RS-3: Single Family, Low Density in consideration of a recommendation to the City Council regarding adoption of an Ordinance; and
WHEREAS, on April 1, 2024 the San Carlos PTC adopted PTC Resolution No. 2024-11 recommending City Council approval of a Zoning District Boundary Map Amendment and Prezoning and Annexation which includes the reasons for the recommendation, findings related to the criteria for zoning amendments in Section 18.35.080 and the relationship of the proposed amendment to applicable general and specific plans; and WHEREAS, on June 24, 2024 City Council conducted a public hearing to consider the application from the property owners of the aforementioned property regarding a Zoning District Boundary Map Amendment and Prezoning of RS-3: Single Family, Low Density in conformance with Chapters 18.27 Common Procedures, 18.35 Amendments to the Zoning Ordinance and Map and 18.38 Prezoning and Annexation Procedure of the San Carlos Municipal Code and to receive PTC Resolution No. 2024-11 recommending approval of such; and WHEREAS, the City finds that a Zoning District Boundary Map Amendment and Prezoning

of RS-3: Single Family, Low Density for the aforementioned property is consistent with the City of San Carlos General Plan and Municipal Code.
SECTION 2: The City Council makes the following findings:
A. Regarding Section 18.35.080 B. Zoning District Boundary Map Amendments of the San Carlos Municipal Code:
1. The change in district boundaries is consistent with the General Plan.
Basis for Finding: The site is proposed for a General Plan land use designation of Single Family, Low Density (3 DUs/Acre) which is consistent and reflective of applicable General Plan policies.
2. The change in district boundaries is consistent with the purpose of this 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: Annexation of this parcel is occurring in an orderly and systematic matter as City jurisdiction and services are currently immediately adjacent to the subject site and would simply be extended to cover this one developed parcel. Annexation will result in clearer and more efficient emergency service to be provided to the site.
3. The change in district boundaries is necessary to achieve the balance of land uses desired by the City, consistent with the General Plan, and to increase the inventory of land within a given zoning district.
Basis for Finding: Annexation of the parcel results in the addition of one new single-family home into the City’s housing stock and a slight increase in the annual property tax revenue to be received. The use and nature of the existing single-family home is consistent and complimentary to the established surrounding land use pattern of other single-family homes in the adjacent City neighborhoods.
B. Regarding Section 18.38.040 Annexation Regulations:
1. The site is located contiguous both to the City boundary and a city maintained street. A fiscal impact analysis has been prepared by an economic development and consulting firm which concludes that the City will receive annual net revenue and that no additional recurring service costs are directly associated. Staff has determined the project to be exempt from the provisions of CEQA per Section 15319 Annexation of Existing Facilities and Lots for Exempt Facilities and Section 15303 New Construction or Conversion of Small Structures. Public services and facilities are determined to be available. The site is a developed parcel and complies with the associated requirements provided within Section 18.38.040(C).
SECTION 3: The approved Zoning District Boundary Map Amendment to prezone the property to RS-3: Single Family, Low Density is set forth in the map listed as Exhibit “A” and with conditions of approval as set forth in Exhibit “B”.
SECTION 4: That the City Council hereby declares that it would have passed this Ordinance sentence by sentence, paragraph by paragraph, and section by section, and does
8.l

hereby declare that any provisions of this Ordinance are severable and, if for any reason any sentence, paragraph or section of this Ordinance shall be held invalid, such decision shall not effect the validity of the remaining parts of this Ordinance.
SECTION 5: This Ordinance shall be published and posted according to law and shall take effect and be in force from and after 30 days after its passage and adoption. *****
I, City Clerk Crystal Mui hereby certify that the foregoing Ordinance was introduced on the 24th day of June 2024 and adopted at a regular meeting of the City Council of the City of San Carlos held on the 12th day of August 2024, by the following vote:

CITY COUNCIL
STAFF REPORT
MEETING DATE: August 12, 2024
ITEM TITLE: Consideration of Introducing an Ordinance Amending San Carlos Municipal Code Title 18 – Zoning, Section 18.04.020 (Land Use Regulations) to Allow Childcare Facilities within Certain Existing Buildings within the RS-3 (Single-family, Low Density), RS-6 (Single- family), and RM-20 (Multi-family 20 units/acre) Zoning Districts.
RECOMMENDATION:
The Planning and Transportation Commission (PTC) recommends that the City Council introduce an Ordinance to allow childcare facilities within certain existing buildings within the RS-3 (Single- family, Low Density), RS-6 (Single-family), and RM-20 (Multi-family 20 units/acre) zoning districts.
FISCAL IMPLICATIONS:
There are no fiscal impacts.
SUMMARY:
The proposed amendments would allow day care centers to be a permitted use in the RS-3 (Single-family, Low Density), RS-6 (Single-family), and RM-20 (Multi-family 20 units/acre) zoning districts if they are to be established in an existing building that was built for and/or previously operated as a legally established public or semi-public use.
BACKGROUND:
Through the strategic plan process, the San Carlos City Council identified the creation, operation and access to childcare as a top priority for the city.
On March 11, 2024, the City Council formally adopted its 2024 Strategic Plan and memorialized childcare as a top priority with the inclusion of the strategic goal that “The City of San Carlos will encourage and support the creation, operation, and access to childcare facilities and reduce barriers to creation and expansion.”
As part of this goal, the Strategic Plan incorporates an objective to consider zoning/co-location options for childcare sites which included the consideration of a zoning update to allow childcare centers in single-family residential districts on sites that were previously schools, religious facilities, or community centers.
Planning and Transportation Commission Recommendation
At the June 3, 2024 PTC meeting, staff presented the proposed Zoning Code amendments to the
9.a
August 12, 2024
Packet Pg. 398
PTC. The PTC adopted Resolution 2024-12 (3 in favor, 2 excused) recommending that the City Council adopt the proposed Zoning Code amendments.
ANALYSIS:
The Municipal Code currently does not permit day care centers in the RS-3 (Single-family, Low Density), RS-6 (Single-family), and RM-20 (Multi-family 20 units/acre) zoning districts. However, there are a number of buildings that were constructed for or previously occupied by public and semi-public uses in which a day care center would be an appropriate use of the space, should they ever become vacant. These previous public and semi-public uses include community assembly (i.e. meeting halls and religious facilities), cultural institutions, and private schools.
The RM-59 (Multi-family 59 units/acre) and RM-100 (Multi-family 100 units/acre) zoning districts already allow day care centers as a permitted use. Further, day care centers are a permitted use in all mixed-use zoning districts except for the MU-DC-100 (Mixed-Use Downtown Core).
The proposed amendments, if adopted, would allow day care centers to be a permitted use in the RS-3, RS-6, and RM-20 zoning districts if they are to be established in an existing building that was built for and/or previously operated as a legally established Public or Semi-public use. This allows for the reuse of existing buildings within these zoning districts while increasing the available locations for day care centers in San Carlos
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), 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.
ALTERNATIVES:
The alternatives available to the City Council include:
1. Introduce an Ordinance amending San Carlos Municipal Code Title 18 – Zoning: Section
18.04.020 (Land Use Regulations) to allow childcare facilities within certain existing buildings within the RS-3 (Single-family, Low Density), RS-6 (Single-family), and RM-20 (Multi-family 20 units/acre) zoning districts; or
2. Do not introduce the proposed Ordinance; or
3. Provide staff with alternative direction.

Basis for Finding: The proposed ordinance amendments would increase access to day care centers throughout the city by allowing them in additional zoning districts. This would also allow providers more options in where to locate their centers. Further, allowing day care centers by- right, when located in an existing building that was built for and/or previously operated as a legally established Public or Semi-public use, would reduce the regulatory and financial barriers to the creation and expansion of childcare facilities in San Carlos.
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 amendment would promote further growth of childcare facilities in the city and would reduce the regulatory and financial barriers to the creation and expansion of childcare facilities in San Carlos by making additional properties available for this use.
SECTION 3: The City Council hereby approves the Municipal Code Ordinance amendment attached as Exhibit A.

CITY COUNCIL
STAFF REPORT
MEETING DATE: August 12, 2024
ITEM TITLE: Consideration of Adopting a Resolution Establishing a Childcare Grant Program Utilizing Funds Collected through the Childcare Development Impact Fees to Increase Childcare Spaces within the City of San Carlos.
RECOMMENDATION:
Staff recommends that the City Council adopt a Resolution establishing a Childcare Grant Program utilizing funds collected through the Childcare Development Impact Fees to increase childcare spaces within the City of San Carlos.
FISCAL IMPLICATIONS:
Fund 26, the Childcare Development Impact Fee Fund, is the source of grant funding to local childcare centers (commercial and in-home). To date, the City has collected Childcare Development Impact fees in the amount of $1,033,530. The approved budget for grant expenditures from this fund for Fiscal Year (FY) 2024-25 is $250,000. This proposed Childcare Grant Program will function on a first-come first-served basis and applications will be accepted on a rolling basis until funding runs low. The City Council may choose to appropriate additional funds if grants exceed $250,000 in the fiscal year. Funding for future fiscal years would come from the remaining fund balance and any Childcare Development Impact Fees collected from future applicable developments.
BACKGROUND:
One of the City Council’s ongoing strategic goals is to increase access to childcare by reducing regulatory and financial barriers to the creation and expansion of childcare facilities in the city. In October 2017, the Council received an informational presentation from staff describing potential strategies to address the shortage of childcare facilities serving the San Carlos community. This presentation was a response to information provided by San Mateo County’s Early Learning Support Services which highlighted the need for additional childcare. At that time, there was a shortage of more than 650 spaces for infant and preschool-aged children in San Carlos.
At the end of 2022, the City Council adopted the Childcare Development Impact Fee (Ordinance 1585 and Resolution 2022-104), which was authorized under the Mitigation Fee Act and applies to new nonresidential development. A Nexus Study was also prepared to determine the appropriate fee levels and plans for how to use the funds. One of the proposed uses of funds was the development of a Childcare Grant Program, available to both commercial and in-home childcare centers located within the City.
