Division 6 — WAREHOUSING DISTRIBUTION/LOGISTICS OVERLAY DISTRICT (SIERRA AVENUE)

Fontana Municipal Code · 2026-09 edition · updated 2026-10-02 · Fontana

Sec. 30-646. - Warehousing distribution/logistics overlay district regulations.

(a)

Applicability. The provisions of this division may be applied to any property with a general plan land use designation of regional mixed use (RMU), and a zoning designation of regional mixed use (R-MU), located on the east side of Sierra Avenue and north of Interstate 210 (I-210) as identified in Figure 1.

Figure 1

(b)

Relation to underlying zoning. The warehousing distribution/logistics overlay district is a flexible designation that is intended to apply in conjunction with, or as an alternative to the provisions in the underlying zoning. When utilized in conjunction with the underlying zone, if the provisions of this division are in conflict with the provisions of the underlying zoning district, the provisions of this division shall apply.

(c)

Intent. The intent of the warehousing distribution/logistics overlay district is to provide for the limited, well planned and orderly development of warehousing distribution/logistic uses on properties within the R-MU zone located on the east side of Sierra Avenue, north of Interstate 210 (I-210), and south of Casa Grande Drive. Additionally, the further intent of this overlay district is to eliminate or adequately mitigate adverse impacts on the community related to such developments and, therefore, projects taking advantage of the overlay development regulations shall be required to provide access to Mango Avenue, thereby limiting and/or prohibiting access onto Sierra Avenue, unless otherwise approved by the Planning Commission and/or the City Council.

(d)

Access. In line with Section 30-646(c), to further ensure the intent of the warehousing distribution/logistics overlay district, Mango Avenue, a collector street as classified in the City's general plan circulation master plan, shall be required to be constructed from Casmalia Avenue to Summit Avenue prior to the establishment of any proposed project-level development, to the satisfaction of the City Engineer. This requirement is to provide an alternate route to Sierra Avenue for properties within the overlay district as a connection to Interstate 210 (I-210). For the purpose of this section, Mango Avenue need not be developed to its ultimate right-of-way width but must otherwise be constructed to a minimum roadway width to provide for two-way truck traffic and any other circulation needs such as maintenance vehicle turn outs, emergency vehicles, etc., as determined by the City Engineer.

(i)

Parking location. Off-street parking shall be located at the rear of the building, but may be considered elsewhere if its use is to further set back buildings from adjacent and/or surrounding sensitive uses (e.g., residential uses across a public right-of-way). Furthermore, visitor and/or employee parking may be located at the front of the building adjacent to the main entry. Service and loading areas may be located at the sides and rear of the building, except where such building sides are adjacent to a public right-of-way.

(j)

Parking and loading requirements. The following are regulations for off-street parking and loading. They identify required number of parking and loading spaces for all new development projects and those proposing substantial modifications to existing buildings. For all parking and loading-related information or regulations not specifically addressed in this section, refer to Section 30-679 et seq. of this Code.

(1)

General parking and loading requirements.

a.

Methods of calculation.

Multiple uses. If more than one use is located on a site, the total number of required off-street parking and loading spaces shall be the sum of the requirements for the various uses computed separately. If individual uses on the same site have a floor area less than that for which loading spaces would be required, then the total gross floor area of all uses on the site or lot shall be used in determining the required number of loading spaces.

Fractional number. Whenever the computation of the required number of off-street parking or loading spaces results in a fractional number, one additional space shall be required for a fraction of .5 or more, but shall not be required for a fraction of .4 or less.

b.

Off-site location. Required off-street parking spaces shall be located on the same parcel as the use that they are intended to serve, unless reciprocal parking and access agreements are recorded between multiple parcels on the same site.

c.

Shared use facility. Required off-street parking and loading spaces may be considered as providing parking or loading spaces for another use where joint facilities serving more than one use contain no less than the total number of spaces deemed necessary for each individual use added together with other uses. Where adjoining uses on the same site have different hours of operation with minimal conflict, the Director of Community Development may determine that some or all of the same spaces may be counted as satisfying the requirements for both uses, provided that the number of spaces shall not be less than the number prescribed for the use requiring the greater number.

(2)

Required number of parking spaces.

a.

Each land use shall provide the number of off-street parking spaces indicated in Table 1—Parking Requirements by Land Use, except as otherwise may be determined by the Director of Community Development per Section 30-650(j)(1)(c) above.

Table 1—Parking Requirements by Land Use
Land Use Motor Vehicle Spaces (Minimum #) GFA—Gross Floor Area Bicycle Spaces (Minimum #)
Distribution, Wholesaling and Warehousing Uses
Logistics and Distribution Facilities (High Cube) Vehicle Parking: 1 space/1,000 sq. ft. GFA for the first 20,000 sq. ft.; 1 space/2,000 sq. ft. for the second 20,000 sq. ft.; 1 space/5,000 sq. ft. for that portion over 40,000 sq. ft. No add'l spaces if office area less than 10% of total building square footage. Office space rate if office area over 10% of total building square footage. None
Warehousing Facilities 1 space/1,000 sq. ft. GFA for the initial 40,000 sq. ft.; 1 space/4,000 sq. ft. of additional GFA greater than 40,000 sq. ft.; 4 spaces/1,000 sq. ft. GFA of office space. Where multiple tenants and or uses occupy the same building, the parking shall be calculated based upon the floor area used by each tenant or use Trailer Parking: 1 trailer space 12 feet x 52 feet for every four bay doors for buildings 199,999 square feet and smaller (round up to nearest whole number). 1 oversized trailer space (12 feet x 52 feet)/5,000 sq. ft. GFA* for buildings 200,000 square feet and larger for the entire building square footage; Parallel parking for trailers (12 x 80 feet) may be utilized as required trailer parking for up to 25 percent of required spaces when demonstrated as usable trailer parking. The area in front of the bay doors and knock out doors shall not be utilized as required trailer parking. *Truck docks and knock out doors shall not be included in this calculation. None

(3)

Required number of loading spaces.

a.

Each land use shall provide the number of off-street parking spaces indicated in Table 2—Loading Space Requirements by Land Use. Requirements for uses not specifically listed shall be determined by the Director of Community Development based upon the requirements for comparable uses and upon the particular characteristics of the proposed use. For other standards (e.g., size of loading spaces, location, turning radius, etc.), refer to Section 30-704 et seq. of this Code.

Table 2—Loading Space Requirements
Land Use Loading Spaces (Minimum #) Type
Distribution, Wholesaling and Warehousing Uses
