Norris Canyon Estates, located between San Ramon Valley Boulevard and Crow Canyon Road, is a gated and hillside Norris Canyon neighborhood with winding private drives and canyon-view homes. The streets trace the folds of Norris Canyon, with Mediterranean-inspired facades and large lots set against oak-dotted slopes. The neighborhood’s character concentrates at the Norris Canyon Road gatehouse, where quiet lanes meet trailhead energy and weekend cyclists pass in small clusters. A short drive away, Canyon Lakes Golf Course & Brewery sets a clubhouse-and-patio rhythm for afternoons. Bishop Ranch’s City Center adds a polished mix of dining and retail in a modern plaza setting. Las Trampas Regional Wilderness frames the backdrop with ridgelines and long, open-sky hikes.

Planned Unit District
A large-scale integrated development or a general plan special area of concern provides an opportunity for, and requires cohesive design when flexible regulations are applied; whereas the application of conventional regulation, designed primarily for individual lot development, to a large-scale development or special area may create a monotonous and inappropriate neighborhood. The planned unit district is intended to allow diversification in the relationship of various uses, buildings, structures, lot sizes and open space while insuring substantial compliance with the general plan and the intent of the county code in requiring adequate standards necessary to satisfy the requirements of the public health, safety and general welfare. These standards shall be observed without unduly inhibiting the advantages of large-scale site or special area planning.
Construct retaining walls according to the provided plans.
