Chapter 15.04 — WATER CONNECTIONS AND FEES

Fees for water service installations shall be those provided from time to time by resolution of the city council. The council shall also establish by resolution such other fees, charges and procedures as may be necessary for the administration of water service.

Whenever water services are to be laid and connected to the water mains of the city, or whenever a property is converted to a more intensive use, the person, firm, or corporation desiring to lay and connect the same or change the use shall apply in writing to the city engineer, through the building permit and development review process, stating the location of the premises effected. Upon receipt of the application, the city engineer shall approve the necessary permits and collect such capacity charges and inspection fees as may be established by the council from time to time. (Ord. 917 § 2, (1970); Ord. 1026 § 1, (1974); Ord. 1996 § 2, (2021))

(a) Any person requesting a connection to water shall, as a condition of such connection pay, the following charges:

Residential

Type Capacity Charges

Single-Family $6,446.00 per dwelling unit

Multifamily

Two or More Bedrooms $4,007.00 per dwelling unit

Studio and One Bedroom $2,613.00 per dwelling unit

Detached Accessory Dwelling Unit (ADU), > $2.69 per square foot
150 square feet

Nonresidential

AWWA Meter Capacity Capacity Charge Per
Water Meter Size Ratio Connection

¾-inch 1.00 $9,756.00

1-inch 1.67 $16,272.00

1½-inch 3.33 $32,510.00

2-inch 5.33 $52,023.00

3-inch 10.00 $97,564.00

4-inch 16.67 $162,619.00

(b) Capacity charges for residential connections are applied per subsection (a) of this section.
For existing singlefamily residential connections, no additional capacity charges would apply to a home remodeling or expansion project, even if the project results in the need
to increase the water meter size whether for fire flow or other purposes. For existing
multifamily connections, capacity charges will apply for new units per subsection (a) based
on number and type and will be credited for existing units, if any, per subsection (a) based
on number and type.

(c) Capacity charges for Accessory Dwelling Units (ADUs) are applied based on square
footage in compliance with the requirements of Government Code Section 65852.2 with
the exception that no capacity charges may be levied on ADUs built within the existing
living area of a primary residence and the total expansion itself is less than 150 square feet.
Capacity charges for detached ADUs and ADUs that are an expansion of more than 150
square feet to the primary residence shall be as per the fees presented under subsection (a)
of this section and these charges will be applied to the entire square footage of the
expansion.

(d) Capacity charges for nonresidential water connections are applied based on the water meter
size of each new connection. Any land use category that does not fall into residential will
be considered nonresidential. For existing nonresidential connections, whenever an upsize
of water meter is required, the property owner is required to pay capacity charges for the
incremental increase in water demand because of the upsize. Water demands are
determined utilizing meter capacity ratios based on American Water Works Association
(AWWA) standard meter capacities. Water capacity charges should not be levied on
irrigation meters or on new private fire service connections.

(e) For a meter size that is not presented in the above table, the costs will be calculated utilizing
the AWWA standard meter capacity of proposed water meter size, using the costs set forth
in subsection (a) of this section for scheduled fees.

(f) These capacity charges do not exempt a developer from having to fund the upsizing of
infrastructure in cases where the existing infrastructure is inadequate to meet the water
demands of the project.

(g) Capacity charges for standard connections are shown above. Connections with higher
levels of estimated water demand than assumed for each customer class maybe assessed
higher charges than shown based on the water capacity charge per gallons per day
multiplied by the estimated volume of water demand of the new or expanded connection as
determined by the city.

(h) The schedule listed in subsection (a) of this section shall be adjusted to conform to the latest
Engineering News Record Construction Cost Index for the city of San Francisco using
13,762 as the base index as of July 2021. The capacity charges listed in subsection (a) of
this section shall therefore be multiplied by the Engineering News Record Construction
Cost Index for the city of San Francisco in effect on January 1, and the result divided by
13,762 to obtain the capacity charge to be implemented.

All moneys received from the collection of the water capacity charges as authorized shall
be deposited with the city treasurer who shall keep a separate and distinct fund and account
to be known as "The Water Enterprise Fund." This fund shall be used, when appropriated
by the council, for the management, maintenance, operation and repair of the water system,
water storage and pumping, for the planning, extension and enlargement of the works.
(Ord. 1996 § 3, (2021))

(a) All fire protection services are to be installed by the owner at his or her expense with the required encroachment permit and inspection by the city public works department.

(b) A double check detector valve of a type approved by the city public works department is required on all fire services and is to be furnished by the owner. Each building with a fire protection service shall have its own separate fire connection with the city water main.

(c) A backflow prevention device, which shall be of a type approved by the director of public works and the health officer, is required on buildings three stories or more in height. (Ord. 917 § 2, (1970); Ord. 1035 § 1, (1975); Ord. 1679 § 4, (2002))

The ownership of this water service installation including the meter, and complete service from main through the meter box shall be vested in the city of Burlingame.

A credit for the cost of the meter on an existing service being abandoned may be claimed when a new larger service replaces an existing service. (Ord. 917 § 2, (1970))

(2) Existing Service Connection. When it is determined in a survey by a city or
environmental health crossconnection control program specialist that an actual or
potential cross connection or backflow condition is present on an existing facility, the
installation of an appropriate backflow preventer shall be required. Should an existing
backflow prevention assembly be in place that does not meet the city's installation
requirements, does not comply with this section, or does not provide adequate
protection with the degree of hazard found on-site, the assembly shall be replaced or
upgraded as required by the city, at the expense of the customer or responsible party.

(f) Surveys.

(1) Identification of Survey Candidates. The city may identify specific industries that might pose an actual or potential backflow hazard to the public water supply. Some of these industries are identified from common lists of industries where cross- connections are likely to be found, as provided by the state of California, the USC Foundation, and other recognized organizations. From these lists, specific facilities in the city's service area may be identified by directories, mailing lists, associations, and business licenses.

(2) Survey. Surveys may take the form of office surveys or field surveys. Office surveys may include determination of facility hazards based on business type or known water use on the facility. Office surveys could also include evaluation of responses to mailed or on-line surveys.

Field surveys may include evaluation of water use by observations made from public or private areas not on the subject facility, or physical inspection on all or a portion of the facility. When possible, a request to survey the facility shall be made at least

24 hours in advance, and a date and time agreed upon with a responsible party. Should the request to survey be denied by a responsible party, notice shall be sent to the customer or responsible party directing installation of the appropriate backflow assembly, at the water meter, based on best available knowledge of the water use and potential hazards at the facility.

During the survey many factors are considered to determine if activities or water use

on facility are or could be a potential hazard to the public water supply. Factors that may be considered include:

(A) Alternative sources of water on site (auxiliary water supplies).

(B) Piping configurations on-site.

(C) Uses of water on-site.

(D) Types of water using equipment.

(E) Condition of water using equipment.

(F) Complexity and elevations of plumbing on-site, and the potential for alterations of that system.

(G) Storage and use of hazardous materials on-site.
