About Sand

Hill

Sand Hill, located between Main Street and the Delta waterways, is a residential and semi-rural Oakley neighborhood with wide-lot streetscapes and open-sky views. The neighborhood’s character concentrates around the Main Street corridor near Vintage Parkway, where coffee counters, local eateries, and small storefronts set a steady, day-to-day rhythm. Housing reads as newer suburban builds mixed with pockets of older ranch-style homes, with driveways, garages, and backyard space shaping the streets. The flat terrain and levee edges give walks and bike rides a long, linear feel. Nearby parks and sports fields add a structured, after-work cadence. The setting stays closely tied to the Delta’s canals, marinas, and seasonal light.

P-1

Planned Unit Development District

A large-scale integrated development, infill 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, infill development, or special area may create a monotonous and inappropriate neighborhood or development. The purpose of the P-1 District is to allow diversification in the relationship of various uses, buildings, structures, lot sizes and open spaces, ensure compatibility with surrounding land uses, and to ensure substantial compliance with the General Plan and the intent of the Municipal 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 a large-scale site or special area planning. The P-1 district may also be used to provide additional zoning control by establishing site-specific conditions of approval and standards for a specific P-1 district.
