a

Title

Article 9, Chapter 3, of the Tustin City Code is and may be cited as the Subdivision Code of the City of Tustin, hereafter referred to as "the Subdivision Code."

b

Purpose and Intent

The purpose of the Subdivision Code is to implement the Subdivision Map Act related to the division of land within or partially within the City of Tustin by establishing regulations concerning the design, improvement, and survey data of subdivisions, the form and content of all required maps provided under the Subdivision Map Act, and the procedure to be followed in securing the official approval of the City regarding the maps. To fulfill these purposes, the intent of the Subdivision Code is to:

  1. Promote orderly growth and development to preserve the public health, safety and general welfare;

  2. Promote open space, conservation, protection, and proper use of land; and

  3. Provide for adequate traffic circulation, utilities, and other services in the City.

c

Authority and Relationship to General Plan

The Subdivision Code is enacted based upon authority vested in the City of Tustin by the State of California, including, but not limited to: the State Constitution and the Subdivision Map Act (Government Code Sections 66410 et seq.).

The Subdivision Code is a tool used by the City of Tustin to implement the goals, objectives and policies established in the Tustin General Plan.

Applicability of Subdivision Code

The type and intensity of land use as shown on the General Plan, any applicable Specific Plan, Article 9, Chapter 2, (Zoning Code), or other applicable provisions of the Tustin City Code shall determine, together with the requirements of the Subdivision Map Act and the Subdivision Code, the type of streets, roads, highways, utilities, and other public services that shall be provided by the subdivider.

9314 - MODIFICATION OF SUBDIVISION REQUIREMENTS

A subdivider may request a modification to any Subdivision Code regulation or requirement, consistent with the following application procedures and findings. This modification procedure shall not apply to modifications of Zoning Code requirements.

a

Application

An application for a modification shall be made by the subdivider on forms and with such fees or deposits as may be prescribed by the Department or by resolution adopted by the City Council. The application shall set forth the nature and extent of the requested modification, the grounds of the application and the facts relied upon by the applicant for the request for a modification and be accompanied by a written statement identifying the special grounds or circumstances that will enable the required findings to be made.

b

Required findings for approval

An application for a modification shall be considered by the City Council concurrently with the application for a tentative map, vesting tentative map, or other application, following receipt of a recommendation on the matter from the Planning Commission. To the extent that provisions of the Subdivision Code conform to the Subdivision Map Act, they may not be waived. In approving or conditionally approving a modification of the regulations or requirements included in this chapter, the City Council shall make the following findings:

  1. Because the land involved in the subdivision is of an unusual size or shape; or is subject to title limitations of record that effect or limit its development; or is affected by topographical location or condition of land involved that affects its development; or the use to which the land involved will be devoted requires the modification, it is impossible or impracticable for the subdivider to conform fully to the regulations contained in this chapter.

  2. The subdivision is in conformity with the Subdivision Map Act, the General Plan, any applicable Specific Plan, Article 9, Chapter 2 (Zoning Code), and other applicable provisions of the Code.
