Charter Oak is primarily flat ground, though the South Hills of Glendora form much of the northern border, and there is a small valley in the southeast quadrant, with Walnut Creek flowing in the bottom. The other major water feature in Charter Oak is the San Dimas Wash, a concrete-lined flood control channel which was formerly the San Dimas River, a tributary of the San Gabriel River. Both Walnut Creek and San Dimas wash flow from east-northeast toward west-southwest, the wash in Glendora and the creek in Covina.

The ground is described as “dry riverbed,” with sandy soil which was suitable not only for the citrus orchards which once were the primary industry in the area, but also for several nurseries growing cactus and other small plants.
