3.54.010 Purpose. The Board of Supervisors

finds:

A. As established in April 1991 by adoption of this chapter and Resolution 88-91, and reconfirmed in the 1996 study titled “County-Wide Traffic Circulation System Model, Transportation Improvement Program and Funding Strategy,” new development creates a cumulative adverse impact on traffic circulation throughout the county, in addition to the project-specific impact, causing the need for both improvement of existing transportation facilities and construction of new facilities to mitigate these new cumulative impacts;

B. Adequate funding to accommodate this need for transportation facilities is not available;

C. It would be infeasible for developers to construct the necessary improvements to mitigate these cumulative impacts caused by individual projects because each project adds a relatively small measure to the total, and the improvement reasonably related to that impact would not be a functional unit able to improve
traffic circulation;

D. A traffic impact mitigation fee is necessary to accumulate sufficient funds to finance these necessary additional public transportation facilities;

E. The fee established and imposed by this chapter partially implements Policy Statements 2.A.4 and 2.A.6. and Implementation Programs 2.A.h, 2.A.m, 2.A.n, 2.A.o,2.A.q, 2.A.t, and 2.A.u in the County General Plan, by requiring development to pay its fair share, providing a mechanism for maintaining adequate levels of service and funding development related components of the Regional Transportation Improvement Program in the County, and ensures that adequate traffic facilities are available to protect the public health, safety and
welfare. Without this fee to mitigate the cumulative adverse traffic impacts, the impacts from development would not be adequately mitigated, the development would be inconsistent with the General Plan, and the public health, safety and welfare would be unacceptably adversely affected by the effects of traffic increases;

F. The purpose of the fee established and imposed by this chapter is to allocate the costs of necessary transportation circulation improvements reasonably among those developments causing the need for the improvements;

G. The use of the fee established and imposed by this chapter is to fund the transportation circulation improvements identified in the Countywide Traffic Circulation Improvement Program;

H. There is a reasonable relationship between the fee’s use and the type of development projects on which it is imposed by this chapter because the fee will be used to improve transportation circulation facilities that have been found to be adversely impacted by increased traffic generated by or attracted to those development projects.

I. A reasonable relationship exists between the need for the transportation circulation improvements and the type of development projects on which the fee is imposed by this chapter because, using the study referred to in paragraph A, (a) trip rate projections for each type of development were calculated using studies of actual traffic patterns associated with each type, (b) these trip rates were compared with the existing road capacity to determine the future transportation circulation deficiencies that will be caused by the development, and (c) the adopted improvement program specifies those transportation facilities necessary to help ensure the additional development-caused traffic will have safe and adequate transportation facilities and the deficiencies will not reduce service levels for existing residents. (Ord. 2254 § 3 (part), 1998; Ord. 1839 §1 (part), 1991).

3.54.030 Establishment of fees.

A. There is established a fee as a condition of approval or issuance of an entitlement for every type of development project, except for a project made exempt from the fee by section 3.54.050, and a project which the community development director determines will not generate or attract vehicle trips. An additional amount of 1% for administration of the fee program is also established as part of the fee.

B. The community development director shall determine the amount of the fee in conformance with this section. For a development project described in the following fee schedule, the fee shall be imposed at the amount designated in the schedule. For a development project not specifically listed in the schedule, the fee established for the most similar listed project shall be used. For a development project which is not sufficiently similar to one listed to ensure the fee adequately mitigates its cumulative impact on traffic circulation throughout the county, the fee shall be determined by calculating the adjusted vehicle trip rate for that type of development project and multiplying the rate times the amount per trip set forth in the fee schedule. Where there are multiple uses with a development project, the fee shall be determined by adding the fee from all uses, except, when the multiple uses are shared within a building in the development project, the primary or predominant use of the building shall be used to determine the fee. For a project in operation on a seasonal basis only, the fee shall be determined by the annual percentage of operation.

C. On July 1 of each year, the fee shall be automatically increased or decreased by the percentage increase or decrease in the San Francisco Consumer Price Index, All Items, all Urban Consumers, published by the U.S. Department of Labor, for the preceding 12-month period.

D. No fee shall be imposed on a development project if (1) a traffic study, approved by the department of public works and the community development director, has been completed which identifies and addresses the project’s direct and cumulative impacts on traffic, and (2) all measures (including any improvements and monetary payments), identified in the study as necessary to mitigate traffic impacts, are implemented.

E. 1. The county department with jurisdiction over the entitlement approved or issued for a development project on which a fee is imposed shall issue or cause to be issued to the project applicant a written notice at the time of final approval which shall state the fee amount (including the automatic adjustment factor) and notification of the commencement of the protest period as required by Government Code section 66020(d)(1).

3.54.040 Fee payment and credits.

A. Except as provided herein, the fee shall be paid to the community development department prior to the issuance of a certificate of occupancy or date of final inspection, whichever occurs first, or if the project does not require a building permit, prior to commencing any activity pursuant to an entitlement granted pursuant to Title 17, or if the project does not require either a building permit or a Title 17 entitlement, prior to the issuance of an encroachment permit or any other entitlement.

B. For a residential development project, the fee shall be paid either (1) prior to the issuance of an authorization for electrical power (“blue tag”) by the community development department division of building and safety, (2) prior to the connection of electrical service to the development, or (3) at the time escrow closes if, prior to the issuance of a building permit, an escrow account has been established for the parcel on which the development is constructed. Proof that an escrow account has been established shall be submitted to the satisfaction of the chief building official. If an escrow account has been established, prior to the issuance of the building permit, the chief building official shall (1) require the property owner to execute a contract to pay the fee at close of escrow, (2) record the contract, and (3) submit a demand to the escrow holder for fee payment. The contract shall be a lien contract within the meaning of Government Code section 66007. The chief building official is authorized to enter into and record these contracts on behalf of the county, and to execute a release of the lien upon satisfaction of the fee obligation.

C. When application is made for a new building permit following the expiration of a previously issued building permit for which a fee was paid, an additional fee is required only to the extent of any increase of the fee since the original fee was paid.

D. If a subsequent development project occurs on property for which a fee has been paid, an additional fee shall be required only for additional development, subject to the fee, that was not included in calculating the prior fee.

E. When a fee is paid for a development project and that project is subsequently reduced so that it is entitled to a lower fee, the community development director shall redetermine the fee and the county auditor shall issue a warrant for a partial refund of the fee.

F. When a fee is paid for a development project and the project is subsequently abandoned without any further action beyond the obtaining of a building permit, the county auditor shall issue a warrant for a refund of the fee paid, less any administrative portion of the fee, upon written confirmation by the chief building official that the building permit has been canceled.

G. If the use of a development project, exempt from a fee at the time of approval, changes to a use that is not exempt, the applicable fee for the changed use shall be paid prior to the issuance of a building permit or Title 17 entitlement
necessary for the change, or on the date of change in use, whichever occurs first.

H. A credit against payment of the fee shall be granted based on the value of (1) transportation improvements, or (2) donation or dedication of land or facilities, which improvements, land or facilities are included in the Countywide Traffic Circulation Improvement Program, or directly reduce the costs of any improvement identified in that Program.
Transportation improvements are any improvements associated with a roadway widening, roadway extension, capacity improvement or traffic signal installation on the Countywide Traffic Circulation Improvement Program, and includes, grading, paving, curb and gutter, sidewalks, transit stops, median islands, channelization, interchanges, relocation of utilities, over crossings, sound walls, bridges, lighting, landscaping, right of way and mitigation of environmental impacts. The eligibility for and amount of any credit shall be determined by the community development director.

I. At the time of fee payment, the county department receiving the fee shall issue or cause to be issued to the project applicant a written notice identifying the Countywide Traffic Circulation Improvement Program as the public improvements the fee will be used to finance. (Ord. 2314 § 20, 1999; Ord. 2254 §3 (part), 1998; Ord 1839 § 1 (part), 1991).
