What is a Development Plan?

A Development Plan Application or Development Plan Amendment Application is required for all new development and additions to existing structures. A development plan identifies the location and architectural style of a building, the type and location of landscaping and the number of parking spaces. Review of a development plan ensures that a project is architecturally compatible with other nearby developments.


An example is developing a shopping center. It is important that center be architecturally compatible with surrounding residential and/or commercial development to enhance the community image. Negative impacts can occur when located next to residential development. Common restrictions include limited hours of operation, soundproofing and noise limits, security guards and parking requirements

Key Questions

  • Does the project achieve the general purposes of this Zoning Ordinance or the specific purposes of the subject zone, or to make it consistent with the General Plan or any applicable specific plan;

  • Does the project protect the public health, safety, and general welfare; or

  • Is the project designed to ensure operation and maintenance of the use in a manner compatible with existing and potential uses on adjoining properties or in the surrounding area?

  • Will the project have any environmental effects? What will those effects be? What level of environmental review must occur?

  • Can the proposed use adequately be served by existing public facilities and services (for example, police and fire protection, parking and roads)?
