Statement of Significance (as of designation - November 24, 1968):
Erected 1867-68, Las Flores Adobe is an outstancing example of a two-story 19th-century "Monterey style" residence. This building combined the traditional Spanish-Mexican adobe with elements of New England frame architecture, including a double veranda across the facade, to create a popular building type unique to California during the mid-19th century. It is located on Camp Joseph H. Pendleton.

Condition:
MCB Camp Pendleton and Headquarters Marine Corps began planning the stabilization of the Rancho Las Flores Adobe in the late 1990's. Planning meetings included representatives from the Base representatives, the California Office of Historic Preservation and the National Park Service. Commencing in FY 2002 to the present MCB Camp Pendleton has partnered with the NPS and University of Vermont. They have studied and developed stabilization measures approved by Base engineering and the CA SHPO. The stabilization has been implemented and limited restoration has been initiated. Studies are continuing exploring possible work beyond stabilization. Invasive vegetation and invasive animal species have been removed.

The Base has expressed a commitment to the protection of the Las Flores Adobe NHL; to that end it is funding development of a long term maintenance plan and has included long term maintenance in its long term budgeting through the year 2013. It has also budgeted for completion of a historic structures report.
