1.4. Findings
• Trees A, B, and C Pinus radiata (Monterey Pines) are confirmed 100% dead and
constitute an imminent fire hazard, as defined by the Cupertino Municipal Code Section
16.54.030 (Fire Hazard Vegetation). Their removal is necessary for public safety and
code compliance. Notice has been sent by the city citing the HOA to remove immediately
due to threat to public safety. All three Pinus radiata showed signs or red turpentine
beetle at the base of the trunks. Red turpentine beetles are an invasive species that are
difficult to treat for. Once an infestation has started pines do not have natural defenses
against them and decline in the tree can happen in as little as 6 months. All three
Monterey pines were 100% dead with no vitality and were removed on 7/3/25.
1.5. Recommendations
Remove Trees A, B, and C immediately to eliminate fire hazard and comply with
Cupertino violation notices. Please see replanting plan to show mitigation effort to
replace lost canopy. All trees listed are 24 inch box size.
