Since its incorporation in 1960, the unprecedented growth of San Dimas has transformed the City from an essentially rural area to a well-balanced community offering industrial, commercial, and residential living. In addition to the 1,700 acre Frank G. Bonelli Recreational Area which lies within the City boundaries, there are many parks such as San Dimas Canyon Park, a city-owned golf course (San Dimas Canyon Golf Club), and over 27 miles of equestrian trails for riding. The city services include an extensive recreational program for youth and for senior citizens, and the City boasts a new modern City Hall, with excellent provisions made for County Sheriff and Fire Departments, along with a fine Los Angeles County Library and Engineering Regional Office.

Tree Preservation
In 1990, the City Council adopted Ordinance No. 913, which serves to preserve and protect any mature significant trees growing in the City. A tree may only be removed or relocated due to disease, development of the subject property, or health and safety concerns affecting the general public.
The owner of a property must first obtain a tree removal permit from the Development Services, Planning Division, before removing or relocating any significant trees(s) from their property. Failure to do so can result in fines or criminal charges being filed. Click HERE for an application form.
A mature tree is defined as “any Oak tree measuring 8 inches or more in trunk diameter, and/or any other species of tree that measures 10 inches or more in diameter, and any multi-trunk tree having a total circumference of 38 inches or more, with at least one trunk having a minimum diameter of 4 inches. The diameter must be measured at a point 36 inches above the ground at the base of the tree.”
Basic knowledge of proper tree care helps individual tree owners understand the quality of care necessary for the health of their trees. Visit www.treesaregood.org/treeowner/treeownerinformation for more information on tree care essentials.
Public/Community Trees

Any permit granted shall contain a date of expiration, and the work shall be completed in the time allowed on the permit and in the manner described in it. A permit shall be null and void if its terms are violated. There shall be no fee attached to a tree permit.
