Marianne –
In answer to the questions regarding zoning designation and residential dwelling unit yield - please see the information provided below received from the city Community Development Director.
The current zoning designations and the approximate maximum residential yield for the 700 acre portion of the Tres Hermanos Ranch property within Diamond Bar is 624.
Please contact me should you need any additional information.

The zoning designations are AG (shown in green) and RH-30 (shown in lavender). The AG designation was carried over from the County zoning map designations of Light Agriculture (A-1)
and Heavy Agriculture (A-2). The RH-30 designation was adopted in 2013 to comply with state RHNA mandates.
The RH-30 zoned property is about 30 acres. The maximum net density is 30 dwelling units per acre. The net buildable area is estimated to be about 16.3 to 17 acres, but the maximum
number of units is capped at 490, which equals our RHNA number for low/moderate income households.
The maximum density in the AG zone is one unit per 5 acres. The zoning district is about 670 acres, so under the current zoning, that would yield 134 units before considering hillside
density restrictions. Areas having slopes of 10% or steeper are subject to Hillside Management standards, and the densities would be less than one unit per 5 acres in those areas:
the steeper the slopes, the lower the densities. For example, in areas where the average slope range is between 26 and 30%, the maximum density is one unit per 5.6 acres (a 10% reduction);
in slope areas ranging between 36 and 40%, the maximum density is one unit per 8.3 acres (a 40% reduction).
I cannot confirm at the moment, but I believe that the 700-acre estimate for Diamond Bar’s portion of Tres Hermanos includes the 100-acre DRHS campus. If so, the base density yield
in the AG zone would be reduced to 114 dwelling units
In sum, the maximum allowable number of units is between 604 and 624 units prior to factoring in slope density reductions for the AG-zoned portion of Tres Hermanos.
