C. Achieve the proper arrangement of land uses envisioned in the Policy Plan component of The Ontario Plan, maintain the stability of existing neighborhoods, and promote the revitalization of areas that require enhancement.

and City Council Priorities components of The Ontario Plan, in a manner that will further strengthen the City’s economic base.

F. Achieve compatibility between Ontario International Airport and the land uses and new development that surround it pursuant to the Ontario International Airport Land Use Compatibility Plan.

G. Establish procedures that ensure land use, development, and subdivision decisions are made in compliance with the California Environmental Quality Act and Guidelines, and environmental impacts are mitigated to an acceptable level and appropriately monitored.

H. Establish comprehensive and thorough procedures for appropriate and effective public involvement in land use, development, subdivision, and environmental decisions, while at the same time processing land use, development, and subdivision applications in an expedient manner.

I. Establish procedures for the open and transparent processing of applications, and information sharing on the parts of administrators, board and commission members, and applicants with regard to all standards, the characterizes of development sites, and the potential impacts of development.

J. Establish reasonable standards and guidelines that promote and inspire innovative and sustainable subdivision, site, building, landscape and infrastructure design, which serves to advance the utility and splendor of the City.

K. Promote the preservation and protection of the City’s historic character and resources.

M. Ensure the provision of adequate and well-designed off-street parking and loading facilities, which are commensurate with the need.

N. Promote safe and efficient pedestrian and traffic circulation systems, and ensure that new development will not overburden the capacity of existing streets, utilities, or community facilities and services.

P. Ensure that the costs of providing land for streets, alleys, pedestrian ways, easements, and other rights-of-way, and for the improvements necessary to serve new developments, are borne by subdividers and developers rather than by the taxpayers of the City at large.

The purpose of this Division is to prescribe procedures for the interpretation and enforcement of the provisions of this Development Code.

1.02 005: Applicability to Existing City Laws

The provisions of this Development Code are not intended to repeal, abrogate, annul, impair, or otherwise interfere with any existing City law, except as specifically repealed by adoption of this Development Code. However, where the Development Code imposes a greater restriction than is imposed or required by an existing law, the provisions of this Development Code shall prevail.

A. Purpose. The purpose of this Section is to establish [i] the authority to interpret the meaning or applicability of the requirements of this Development Code, either generally, or as applied to a specific case or situation; and [ii] the authority and procedure for land use determinations, as not every conceivable land use can be identified by this Development Code or applicable specific plans of the City.

B. Applicability.

1. Whenever the Zoning Administrator determines that the meaning or applicability of any of the requirements of this Development Code require interpretation, they shall be empowered to make such interpretation. Furthermore, as every conceivable land use cannot be identified by this Development Code or applicable specific plans of the City, the Zoning Administrator may compare and measure a proposed land use against those listed in this Development Code or an applicable specific plan, which have similar impacts, functions and characteristics.

2. When a land use is not specifically listed in Table 5.02-1 (Land Use Matrix) of this Development Code, or the list of allowed land uses in a specific plan of the City, the Zoning Administrator may determine that the land use is allowed, if it is determined to be similar to other land uses in the same zoning district or applicable specific plan land use district. In determining “similarity,” the Zoning Administrator shall consider the following, as applicable:

a. Volume and type of sales (retail or wholesale), the size and type of items sold and nature of inventory on the premises;

Page 1.02-1

Ontario Development Code

(Rev. 12.01.2020)

d. Type, size and nature of buildings and structures supporting the use;

e. Number and density of employees and customers, business hours and employment shifts;

f. Transportation requirements (including modal split for people and freight) by volume, type, characteristics of traffic generation to and from the site, and trip purposes;

g. Parking characteristics, turnover and generation, and the ratio of the number of spaces required per unit area or activity;

h. Predilection for attracting or repelling criminal activity;

i. Amount and nature of nuisances generated on the premises, such as fumes, glare, noise, odor, radiation, smoke, and vibration; and

j. Special public utility and services requirements, such as communications towers/antennas, power structures, pretreatment of emissions or wastes, wastewater discharge and water supply.

C. Request for Interpretation or Land Use Determination . A request for an interpretation or land use determination shall be filed with the Planning Department, and shall identify each specific provision or land use in question, and any other information necessary to assist the Zoning Administrator in their review. Any interpretation or land use determination made pursuant to this Section may be appealed pursuant to Division 2.04 (Appeals) of this Development Code.

D. Application of Interpretations/Land Use Determinations in Similar Situations.

1. An interpretation or land use determination made pursuant to this Section shall apply in all similar situations, unless modified on appeal, or by subsequent Development Code Amendment.

2. Once an interpretation or land use determination is decided, an application for substantially the same interpretation or determination of use shall not be considered, and the filing of a Development Code Amendment pursuant to Section 4.01.020 (Development Code Amendments) of this Development Code, shall be required.

E. Promotion of the Public Health, Safety and Welfare. Land use determinations and interpretations in the application of the provisions of this Development Code shall be held to the minimum requirements necessary for the promotion of the public health, safety and welfare.

F. Clarifying and Interpretive Materials.

The Zoning Administrator shall cause the immediate removal of any interpretive materials that have been included in this Development Code pursuant to Subsection C (Incorporation of Clarifying/Interpretive Materials), above, which have been affected by a Development Code amendment or modification on appeal.

G. Establishment of Operational Performance Standards.

1. In making a land use determination, the Zoning Administrator may require certain safeguards and impose certain operational performance standards established to ensure that the purposes of this Development Code or applicable specific plan are maintained; ensure that the project will not endanger the public health, safety or general welfare; ensure that the project will not result in any significant environmental impacts; ensure that the project will be in harmony with the area in which it is located; and ensure that the project will be in conformity with The Ontario Plan and any applicable specific and/or area plan(s).

2. All operational performance standards or other requirements authorized by this Section are enforceable in the same manner and to the same extent as any other applicable requirement of this Development Code or applicable specific plan.

The analysis should consider whether the interpretation or determination will be sufficiently common or recurring in the future, to justify a text amendment, or so unusual or rare that an amendment is not necessary. The analysis shall also identify all zoning districts where the new use(s) could be listed, as well as any special operational conditions, standards or limitations that should be imposed on the use(s).
