The Limoneira Company, founded in 1893 and one of California’s oldest agribusinesses, has been developing neighborhoods in Santa Paula since the 1890s. The 500-acre East Area One Plan was organized as three walkable neighborhoods and a civic facilities district, while preserving agricultural land on the hills. The Plan defines a fine-grained network of pedestrian-oriented streets, parks and other public spaces, and a range of residential, live-work, mixed-use and light industrial building types in a number of regionally based architectural styles.

Special land use and planning standards encourage a mix of uses compatible with the railway and appropriate to the Santa Paula Railroad District. These standards define building types and architecture, complementing the scale and character of the adjoining new neighborhoods. Hallock Plaza is the signature public space in this district, pro­viding outdoor areas for dining and other community activities. The plaza is located at the junction of the mixed-use neighborhood center to the north, the employment-oriented Railroad District, and the Civic District, which contains schools, parks and other community facilities.
