The project is located near the corner of Lone Tree Way and Mokelumne Dr. and sits prominently above the street on a flat portion of a parcel carved out of the hillside.  The highly visible location offered marketing advantages as well as entitlement challenges since the site is right at the transition between commercial and residential land uses.

With the original zoning slated for a church, Cubix had to work closely with the developer and City Staff to obtain approvals to change the General Plan, the Specific Plan, and the Zoning to allow a spot zoning, or Planned Development, for a Self Storage facility. 

In addition to the entitlement issues, the site presented a unique challenge to fit into the hillside condition and to distribute the massing of the buildings so as to minimize the impact along the street frontage while also considering site lines from the adjacent residential neighborhood sitting above the project, all while maximizing rentable area for the developer.  This was accomplished by strategically placing a one story building along the street, a three story in the middle of the site, and then a two story cut into the hillside below the adjacent home's site lines.  All the visible portions of the buildings were softened with horizontal and vertical articulations and the use of stucco finishes, cornices, stone wainscoting, faux windows, awnings, and extensive landscaping.

In order to maximize useable area the site’s plateau needed to be expanded which was acheived by employing extensive retaining walls both above and below the building pad.  On the lower side of the site, tiered interlocking block walls totaling over 11’ high with layers of geo grid were installed at the northeast corner of the site.  On the upper side of the site steel I beams encased in concrete with concrete planks between added up to another 4’ of retainage.  Due to a proximity of just 0.1 miles from the Antioch Earthquake Fault, the foundations for some of the retaining walls had to be as deep as 38’.
