(Ord. No. 1445, 12-23-08)
4.33.030 - Definitions.¶
When the following words or phrases are used in this chapter, they shall have the meaning ascribed to them in this section:
A. "Applicant" means the owner(s) of real property who directly, or through a developer, submits an application to the planning and building services departments for any new development of land including, but not limited to, specific plans and related tract maps, that will eventually require the issuance of building permits.

"Facilities" means any long-term capital facilities, services, equipment or improvements related to the county traffic circulation system, the costs of which may include construction, grade separation improvements, right-of-way purchases, related environmental mitigation and design and construction administration.
F. "Improvement" means any modification, alteration or addition to portions of the county traffic circulation system, the costs of which may include construction, grade separation improvements, right-of-way purchases, related environmental mitigation and design and construction administration.
G. "Multifamily dwelling" is any structure or portion thereof that contains three or more dwelling units and, for the purpose of this chapter, includes residential condominiums.
H. "New development" means all construction for which a building permit or other permit to operate is required.
I. "Single-family dwelling" is any structure or portion thereof that contains living facilities, including provisions for sleeping, eating, cooking and sanitation as required by the Uniform Building Code, for not more than one family unit.
J. "Traffic impact fees" ("fees") mean any and all fees set out in this chapter which:
(1) Help mitigate the direct and cumulative traffic-related impacts that new development has upon the roads and traffic circulation within the county; and
(2) Maintain county roads and traffic circulation at levels conducive to the public health, safety and general welfare of the citizenry.
K. "Unincorporated areas" means any and all areas not incorporated within a city and located within the County of Imperial's sphere of influence.

(Ord. No. 1445, 12-23-08)
4.33.040 - Findings.¶
The board of supervisors finds and determines that:
A. The County of Imperial seeks to protect public health, safety and general welfare by ensuring that adequate facilities and services are provided within the unincorporated areas.
B. It is county policy, by and through its general plan and the provisions of this chapter, to assure that necessary and adequate traffic-related facilities required by new development projects are either available or will be made available as a condition of approval of such projects and that the cost of providing such adequate facilities are collected on an equitable basis from the beneficiaries thereof.
C. New development will result in degradation of traffic levels of service on the regional transportation system of streets, arterials and highways throughout the county.
D. The traffic impact fees ("fees") are intended to finance traffic-related public facilities which help mitigate the direct and cumulative traffic impacts of new development in the county.
E. In order for the county to construct, acquire, expand or improve on needed facilities, it is necessary to require that all new development bear its fair share cost of providing the traffic-related facilities reasonably needed to serve that new development.
F. In order to establish the fees set forth herein, area-specific impact fees studies along with related findings have been prepared, reviewed and considered and are specifically cited and referenced relative to its respective fee schedule.
G. There is a reasonable relationship between the use of the traffic impact fees to pay for the construction of county transportation improvement projects and the type of development for which the fee is charged in that all new development in the county, both residential and nonresidential, will generate or contribute to the need for the transportation projects in different degrees as further described in their respective traffic studies.
H. As indicated in the respective impact fee study, the fees set forth herein will be used to recover the cost of traffic-related facilities, but only to the extent that the need for facilities is a consequence of new development that is subject to the fees, thereby ensuring that there is a reasonable relationship between the need for the facilities and the type of new development being assessed such impact fees.
I. The causes of impact upon county roads do not stop at jurisdictional boundaries and, particularly in the case of all new development adjacent to those boundaries, traffic impact fees need to be imposed in order to finance those impacts that can be attributed to that development by professionally prepared traffic studies.
J. Traffic impact fees are hereby created for the foregoing purpose and reasons.
(Ord. No. 1445, 12-23-08)
4.33.050 - Prior agreements and conditions of approval.¶
A. Any enacted enforceable agreement existing prior to the operative date of this chapter between an applicant for development and the county's planning and development services department, public works department or appropriate department for general government, pertaining to the dedication of land or payment of fees for traffic-related facilities, equipment or improvements to serve the property which is the subject of the application, or any portion thereof, satisfies the requirements of this ordinance. Applicant shall present such evidence to the planning and development services department prior to the issuance of any building permit.
B. If land, facilities, equipment or improvements were dedicated and accepted by the county to the planning and development services department, public works department or appropriate department for general government as a condition of approval of a discretionary permit prior to the operative date of this chapter, such dedication or donation shall be considered as satisfying the requirements of this chapter for such discretionary permit. Applicant shall present such evidence to the planning and development services department prior to issuance of any building permit.
(Ord. No. 1445, 12-23-08)
4.33.060 - Imposition of fees.¶
Except as otherwise provided by local, state or federal laws or other exemptions as set forth in Section 4.33.100, fees shall be assessed and levied upon any owner(s) of real property located in the unincorporated areas or within incorporated cities (if so specified under Section 4.33.070) in connection with: adding one or more dwelling units to such property, including the construction of a new dwelling unit or the installation of a manufactured home on the property; adding industrial (or agricultural related), commercial or office units to such property; constructing an addition of chargeable space to an existing industrial (or agricultural related), commercial or office structure on the property; or converting a land use to a more intensive use on such property thereby creating a greater need for infrastructure facilities. Said fees are to be in amounts determined necessary to fund the acquisition, development and/or improvement of facilities required to serve the cumulative needs of those persons residing, working or studying in or otherwise using such units or property as outlined in referenced traffic impact fee studies. Furthermore, the fee, as imposed herein, can serve as mitigation, along with other mitigations, for such congestion and related adverse impacts, as appropriate, and as determined by the full analysis of the impacts of each new development.
(Ord. No. 1445, 12-23-08)
4.33.070 - Amount of fees.¶
The amount of the fees assessed and levied pursuant to the provisions of this chapter shall be as set forth in the tables below, except as reduced by a credit pursuant to Section 4.33.090 or exempted by Section 4.33.100 and shall be applicable as to all projects of the types as specified in Section 4.33.060 for which application is made for a development permit on or after the effective date of this chapter.
(A) Central Imperial County Traffic Impact Fees.
Applicable Fee Area. The Central Imperial County Traffic Impact Fee area, hereinafter referred to as the "fee area," is defined as that area bounded by Aten Road to the south, Forrester Road to the west, Schartz Road to the north, and State Route 111 to the east.
Impact Fee Study Basis. The basis of the Central Imperial County Traffic Impact Fees is the "Central Imperial County Traffic Impact Fee Study" (herein after referred to as the "study") prepared by KOA Corporation and dated March 2008. Said study provides the methodology underlying the specified fee schedule based upon projected road improvements, safety infrastructure measures and associated costs available at the time of the preparation of said study.
Fee Schedule.
a. Residential (per dwelling unit):
| Land Use | Fee |
|---|---|
| Residential (single-family) | $8,250 |
| Residential (multifamily) | $6,600 |
| Residential (senior community) | $3,300 |
b. Nonresidential (per 1,000 square feet or ksf):
| Land Use | Fee |
|---|---|
| Commercial (Office) | $16,500 |
| Commercial Retail (specialty) | $33,000 |
| Commercial Retail (neighborhood) | $99,000 |
| Commercial Retail (community) | $66,000 |
| Commercial Retail (regional) | $41,250 |
| Golf Course | —— |
| Industrial Park | $6,600 |
| Warehousing | $4,125 |
| Manufacturing/ |
$3,300 |
| Heavy Industrial | $1,238 |
c. Other Undesignated Uses. Uses not otherwise designated in subsections 4.33.070.A.3.a. and 4.33.070.A.3.b. will be calculated using the Guide of Vehicular Traffic Generation Rates for the San Diego Region (April 2002) and the Trip Generation Rate charts of the Institute of Transportation Engineers as a guide, whereby the specific proposed use equates to projected Average Daily Traffic (ADT) with ten (10) ADTs equal to one EDU for determining the fee established in the study. One EDU equals $8,250.
d. Fair Share Fees for Adjacent and Incorporated Areas. Fair share fees for new development outside the fee area, either in the unincorporated area or within incorporated cities lying along city boundaries immediately adjacent to said fee area, will be subject to a traffic impact fee. This fee will be determined by the planning and development services department and the public works department on a case-by-case basis using project-specific traffic studies and analyses to determine their contribution to impacts along specific roads and intersections within the fee area. Fees will be imposed, collected and administered as established within this chapter. Under no circumstances will the fees imposed exceed those established in subsections 4.33.070.A.3.a. and 4.33.070.A.3.b.
Phase-In of Fees. The fees specified in this section shall be phased-in, upon adoption of this chapter and benchmarked upon the date of project approval by either the county planning commission or the board of supervisors, pursuant to the following schedule: three months following adoption sixty percent (60%) of fee is applicable, one year following adoption eighty percent (80%) of fee is applicable and two years following adoption the full fee is applicable.
Periodic Review, Revision and Update. Periodic review, revision and update of the assumptions underlying the March 2008 "Central Imperial County Traffic Impact Fee Study" and its associated fee structure will occur no less than every five years and related adjustments to the fee schedule within this section may be modified by appropriate amendments to this county ordinance [Ord. No. 1445]. Any adjustments or modifications made to the fee structure must be made based on documented changes to the findings arising from said review, revision and update.
(Ord. No. 1445, 12-23-08)
4.33.080 - Fee adjustment.¶
Commencing two years following the effective date of this chapter, any and all fees as established and imposed herein may be increased or reduced on October 1 of each subsequent year based upon the Engineering News Record Building Cost Index for Los Angeles Metropolitan Area (BCI) unless the fees are otherwise adjusted by the board of supervisors due to extenuating circumstances exacerbated by severe economic conditions. The county executive officer shall compute the percentage increase, if any, between the BCI on July 1 of each year and the July 1 BCI for the previous year. The county executive officer shall then adjust by such percentage the fees established and imposed by this chapter. The adjusted amounts shall be rounded to the nearest dollar. These amounts shall constitute the fees authorized pursuant to this chapter. Should the BCI be revised or discontinued, the county executive officer shall use the revised index or a comparable index, as approved by the board of supervisors, for determining fluctuations in the cost of development. Nothing herein shall prevent the board of supervisors from electing to retain existing fees or from electing to waive the inflation adjustment for any given fiscal year.
(Ord. No. 1445, 12-23-08)
4.33.090 - Credits.¶
Traffic impact fees required for any development project may be reduced by the following credits:
A. Credit for Applicant-Dedicated Land, Rights-of-Way or Construction of Prescribed Facilities/Improvements: The county may grant to project applicants or owners of real property, a credit against the specific total calculated fees, which would otherwise be charged pursuant to this chapter, for the dedication of land, rights-of-way and/or construction of prescribed facilities/improvements as determined in the study. The amount of the credit granted shall be determined on a case-by-case basis by (1) an estimate of the fair market value of the land dedicated as established by an appraiser selected by, or acceptable to, the county or (2) by an estimate of the costs of constructing facilities, including structures, equipment and improvements, as established by original receipts provided by the applicant for work performed by duly licensed contractors recognized by the county. All projected construction work, equipment purchases and related costs to be credited must be reviewed and preapproved by the county prior to commencement of any construction activity. Under no circumstances shall a credit be given for the cost of improvements not defined herein as "facilities" or otherwise inconsistent with the study.
B. Credit for Innovative Project Design That Reduces Off-Site Traffic Impacts: The county may grant to project applicants a credit against the specific total calculated Fees if it can be demonstrated/proven that innovative project design of the circulation system for their respective projects would reduce off-site traffic impacts that are used as a basis for establishing needed road improvements and related safety infrastructure measures outlined in the respective study for their underlying fee area. Said reduction to off-site traffic impacts must be supported by project-specific traffic studies/analyses prepared by consultant(s) acceptable to the county and provided either by the project applicant or as determined as part of the CEQA process. The study must demonstrate/prove why, where and by what percentage off-site impacts are reduced. The determination of any credit reduction in such cases will be made by county traffic engineer.
C. An applicant for development approval may apply for credit to reduce the amount of the fees required to be paid at the time of development approval by the county. Any credit granted and the amount of the fees to be paid shall be included as a condition of approval for development. If an applicant has received development approval from the county and has not previously applied for a credit to reduce the amount of the fees required to be paid, an applicant may apply for such credit with the county executive officer prior to the issuance of a building permit and the county executive officer shall make a recommendation thereon to the board of supervisors. The board of supervisors shall determine the amount of any credit to be allowed. The applicant shall be given notice of the county executive officer's recommendation and the time when the board of supervisors will consider the matter. The applicant may appear and present evidence with regard to the requested credit.
