Municipal Code Text Amendment 20-0005; Specific Plan No. 11

Project Description:

Consideration of a Municipal Code Text Amendment of Title 18-Zoning, Chapter 18.518 Specific Plan 11 of the San Dimas Municipal Code, to amend grading limits within Planning Area I and make various clean-up text amendments.

The proposed Municipal Code Text Amendment (MCTA) would allow for up to one thousand (1,000) cubic yards of grading, cut and fill, beyond that grading necessary for the primary residence, driveway and garage for properties located within SP-11 Planning Area 1 (36 residential lots, up to 36,000 CY grading). Per the previous Development Plan Review Board policy, a swimming pool and five (5) feet of decking surrounding the pool were exempted from the additional grading calculations, and will be codified as part of the proposed MCTA. The proposed MCTA would also include development standards for the grading, landscaping and any retaining walls that the additional grading would require. Additional clean-up items are proposed by removing sections which dealt with the initial development of the area and codifying previous policies regarding Conditional Uses within the specific plan.

Project Location:
The Project Site is located within the southwestern portion of the City and is located within Specific Plan-11. Specific Plan-11, Area I is bordered by Puente Street to the north, Via Verde to the southeast, East Covina Hills Road to the southwest and the City of Covina to the west. The majority of the Specific Plan has been developed with single-family residences within hillside areas and is surrounded by existing hillside single-family residences. Local access to the Project Site is provided by Via Verde and regional access is provided by the San Bernardino Interstate-10 (I-10) Freeway, approximately 1-mile to the south.
