Arboretum Specific Plan

Project Location

The Arboretum Specific Plan (PDF) area is located on the northern portion of the City of Fontana in west San Bernardino County, approximately 50 miles east of the City of Los Angeles and 16 miles north of the City of Riverside. Interstates 10 and 15 and Highway 210 provide regional access to The Arboretum and to the City of Fontana.

Additionally, The Arboretum Specific Plan area is located adjacent to established residential neighborhoods in northern Fontana, eastern Rancho Cucamonga, and western Rialto. Undeveloped hills and single-family residential properties characterize the majority of surrounding land uses.

Northwest of the specific plan area are the foothills of the San Gabriel Mountains and to the northeast lie the foothills of the San Bernardino Mountains. Both are major landforms in northern Fontana as well as Southern California. The Lytle Creek Wash is another major geographical feature northeast of the project area.

Project Description

The Arboretum will be developed to accommodate residents of varying lifestyles and will accommodate a broad range of residential housing types and amenities. The Arboretum is envisioned as master-planned community on 531.3 gross acres and will contain the following:

  • Maximum of 3,526 residential units
  • Two school district sites
  • Private and public recreational facilities
  • Activity center

The development of the Arboretum will enhance the image of the area with the provision of new roads and signature landmark landscaping, landscaped parkways, and entry monuments. The Arboretum will have parks, gardens, and trails which will tie the community together.

Levels of Community Design

The Arboretum is comprised of three levels of community design:

  • Community
  • Village
  • Neighborhood

The Arboretum’s major thoroughfares (Citrus Avenue, Sierra Avenue, Grapeland Street, Duncan Canyon Road, Casa Grande Avenue, and Cypress Avenue) will contain landmark landscaping that will clearly define the community edges and establish a visual impression of the significance of this project in relation to other developments nearby.
