This list will contain landmark trees, special trees of beauty, stately trees which contribute to an entire neighborhood, dedicated trees, etc. These trees will be identified, mapped and recorded. Subsequent to this they will be given special treatment to retain them, as deemed appropriate by the General Services Director. If said special treatment is not determined to be adequate to retain the identified tree, a full report shall be made to the Commission before any other action is taken. Whenever it is necessary to prune tree roots in parkways or other public areas in order to correct or prevent damage being caused by the subject tree, every reasonable effort shall be made to save the tree. It will still be necessary to meet the City's standards relative to grades and alignments, with the exception of those special trees discussed in Paragraph 1 of this policy statement If it is necessary for a tree other than that included in Paragraph 1 to be given special treatment, each tree shall be considered individually on its own merits to determine whether the tree should be retained or replaced. all parkway trees included in this category must be subjected to and meet the following criteria: 1. Have a tree hazard evaluation performed by the City arborist Attachment 2). 2. Have sufficient life expectancy to merit special consideration. 3. Have contiguous property owners be desirous of retaining the tree if special treatment of other than the sidewalk repair is necessary to retain it 4.

Application of the criteria on parkway trees will be conducted by the General Services Department in coordination with the Parks, Beaches and Recreation Commission.

The Parks, Beaches and Recreation Commission is required to establish a standing Street Tree Committee to assist the Commission in developing a community awareness program and provide input to the total street tree program. Objectives of this Street Tree Committee will be: 1. To obtain /provide representation for each situation as it arises in a community and /or neighborhood. 2. To recommend innovative and practical techniques that will enable trees to be saved when imrovements are performed around them. is 3. To provide recommendations to the Parks, Beaches and Recreation Commission when tree removal requests are denied by the City arborist and appealed to the full Commission. 4. To inform the public and further the philosophy of the value of trees in a community. 5. To pursue procedures whereby larger replacement trees can be used when trees are removed. 6. To assure that no community has a mass removal effect as projects occur. 7. Annually review landmark tree locations for inclusion in Council Policy G -1. When a tree is removed from the parkway for the sole benefit of the adjacent property owner, the property owner will be responsible for the cost of removal. Removal must still be done in accordance with City approval. 2 is Note: (See Attached List - Preservation of Special Trees) See Attached - Tree Hazard Evaluation Form) Adopted May 9,1966 Amended August 14, 1967 Amended November 9,1976 Amended November 12,1985 Amended November 28,1988 Amended March 14,1994 Amended April 11, 1994 Formerly I -9 3 G -1 Attachment, G -1 QTY OF NEWPORT BEACH PRESERVATION OF SPECIAL TREES Location Species LANDMARK Balboa Library Eucalyptus globulus TREES Balboa Library Phoenix canariensis West Jetty (near Historical Marker) Phoenix canariensis Dover Drive at Westcliff Liquidambar styraciflua 400 block Poinsettia Eucalyptus corynocalyx Ocean Blvd. Corona del Mar Phoneix canariensis Westcliff & Dover (Groves) Eucalyptus globulus In Arches Overpass Eucalyptus lehmannii DEDICATED No. Mariners Park TREES Marcie Schrouder) Pinus radiata Mariners Park Frank Tallman) Pinus radiata No. City Hall grounds Billy Covert) Ficus benjamina City Hall grounds Walter Knott) Pinus halepensis City Hall grounds Calif.
