San Dimas City Zoning Code

The purpose of Specific Plan No. 12 is to provide for the classification and development of parcels of land as coordinated, comprehensive projects so as to take advantage of the superior environment which will result from large scale community planning. The regulations established by Specific Plan No. 12 are intended to allow a diversity of uses. Development standards are created specifically for the project area while ensuring substantial compliance with the intent of this code. Alternative development standards have been incorporated in this specific plan in return for development sensitivity and increased amenities to serve the inhabitants of this and surrounding community areas.

Development standards are proposed to achieve the following objectives:

Unless otherwise specified, all development within Specific Plan No. 12 shall comply with this code. Terms used in this chapter shall have the same meanings as defined elsewhere in this code.

Any details or issues not specifically covered by this specific plan shall be subject to the regulations of this code.

The approval of development within the specific plan area shall be governed by Section 65450 et seq., of the Government Code.

All construction within the boundaries of the specific plan shall comply with all provisions of the Uniform Code and the various mechanical, electrical, and plumbing codes adopted by the city.

Minor modifications to the specific plan which do not give rise to a conflict with the intent of the specific plan as approved, may be approved by the director of community development at his or her discretion.

An environmental impact report which analyses the "worst case" situation for the accumulative impacts for the physical and economic development proposed by the specific plan, has been certified by the city council and is referenced by this subsection.

The area of each planning area is calculated in gross acres exclusive of major perimeter roadways.

Any land use designation not specifically covered by Specific Plan No. 12 shall not be permitted.

If any regulation, condition, program or portion thereof of the specific plan is for any reason held invalid or unconstitutional by any court of competent jurisdiction, such portion shall be deemed a separate, distinct and independent provision and the invalidity of such provisions shall not affect the validity of the remaining provisions of this chapter.

The maximum number of allowable dwelling units and their approximate location is established for each residential planning area as specified in the land use development plan, Exhibit

The maximum number of buildable lots and residential units are established on the tentative tract map at the time of approval by the planning commission and the city council based on the topographic conditions, minimization of grading, street and lot layout, orientation of structures and the need for open space.
