San Dimas Municipal Code Art. II Land Uses

In Planning Area Two areas identified for potential development consistent with the goals and objectives of Specific Plan No. 25 are depicted on Exhibit B attached to and located at the end of this chapter.

(Ord. 1106 § 1, 1999; Ord. 1201 § 1, 2011)

A. The incorporation of the planning area concept into this specific plan creates the opportunity to apply the maximum allowable density and some development standards differently to unique parts of this specific plan. This is beneficial due to varying opportunities for clustered development, access and utilities. The two planning areas are depicted as set forth on Exhibit A located in Section 18.542.630.

B. Planning Area One (PA1) consists of three hundred ten plus or minus acres at the southwesterly portion of the specific plan.

C. Planning Area Two (PA2) consists of nearly seven hundred acres comprising the remainder of the specific plan.

(Ord. 1201 § 1, 2011; Ord. 1236 § 1, 2016)

A. The maximum allowable density for Planning Area One shall be 0.225 dwelling units per acre, not to exceed sixty-five dwelling units.

B. The maximum allowable density for Planning Area Two shall be as shown in the following table:

Table 18.542.110 Maximum Allowable Density

C. Achievement of the maximum development intensity cited above is not guaranteed; the actual yield of any development is to be determined based upon:

1. Site-specific physical characteristics;

2. The need for mitigation or avoidance of impacts to biological habitats;

3. The environmental sensitivity of proposed site design, grading and type of construction;

4. Available on-site and off-site access and circulation; and

5. The ability of the proposed project to avoid impacts on other properties.

D. Individual developments within Specific Plan No. 25 must be consistent with the general policies and actions contained in the General Plan. It is specifically acknowledged that a project that meets applicable development policies might not achieve the maximum development intensity for the site.

E. Within the Specific Plan No. 25 area, there are existing lots of record that exceed the maximum development densities cited above. For these parcels, one single-family dwelling unit may be permitted without compliance with maximum allowable density and minimum lot size but subject to all other regulations and requirements of this specific plan.
