164 Unit Condominium Project located behind 464 E. Bonita Avenue

Project Description:

A Vesting Tract Map for condominium purposes was approved by the City Council on October 14, 2025, for the development of 164 Units (attached two- and three-stories), 17 of which will be affordable units (moderate-income). As part of the project an amendment to the Housing Element to reallocate 89 units across affordability levels from the subject site to seven (7) other existing housing sites (No’s 4, 5, 7, 9, 10b, 11, 12), reduce the density of the subject site from 45-55 DUA to 16-25 DUA, and create two sites from Site #13 (13a & 13b); Development Plan Review for the architectural and site layout review, and the associated removal of a total of 116 trees (80 mature and 36 non-mature trees). Construction is proposed to begin mid-2026.

This will be a for sale project, including the affordable units. The 9.19-acre, multi-family development will be a gated community access off Bonita Ave. The project has been designed in a contemporary Spanish style architecture that will include, but not limited to recessed accents, arches, boxed bay windows, metal Juliet railings, canvas window awnings and decorative corbels. Given the scale of the proposed development, there will be a mixture of unit types and also a mixture of building cluster types. The developer is proposing nine (9) different unit types ranging in size from 1,286 square feet to 2,036 square feet.

Project Location:

The Project Site is Located just East of 444 E. Bonita Ave. (APN’s: 8390-016-008 & 8390-014-025) on a portion of land that was previously owned by the U.S.D.A. Forestry Service Technology and Development Center

Environment Review:

The project is exempt under Government Code Section 65457 and CEQA Guidelines 15182 (c) as the proposed development has been previously analyzed under the Environmental Impact Report (EIR) (SCH No. 2022110018) for the DTSP. The EIR analyzed development of all parcels within the boundaries of the DTSP. The subject site, which is a portion of Housing Element Site #13, was analyzed for a maximum build out capacity at 45-55 units per acre. Applying the max density to the Applicant’s 9.19-acre site, a maximum of 505 units could be developed on the subject site. As long as the proposed development, or any other development within the DTSP, does not exceed the maximum build out analyzed in the EIR, there is no further environmental review required. In this case, the Applicant has proposed a development of 164 units with a density of 17.8 units per acre, significantly below the maximum build out analyzed in the DTSP EIR. While the proposed development is exempt from further CEQA review, focused technical studies, including but not limited to Air Quality, Traffic and Sewer studies were still required to ensure there were no impacts caused by the proposed development. These studies have been completed and reviewed by City Staff and it was determined that no impacts are anticipated from the proposed development.

In addition to the proposed development, the amendment to the Housing Element must also be considered for CEQA review. The proposed amendments consist of reducing the designated density of 45-55 units per acre to 16-25 units per acre for a portion of Site #13, creating two sites from Site #13 (Site #13a & Site 13b), and transferring unit capacities across affordability levels to address No Net Loss. The proposed amendments will not increase the number of Housing Element Housing Sites, nor will they increase the density of the existing Housing Sites; therefore, they will not impact the Housing Element’s current compliance nor are there any anticipated impacts from the proposed changes. As such, the proposed amendments are exempt pursuant to CEQA guidelines Section 15061(b)(3); CEQA does not apply to this item because there is no potential for causing a significant effect on the environment. Therefore, no additional environmental review is needed at this time for the Housing Element amendment or the development of the 164 units.

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.
