SUMMARY

Memorial Park has approximately 80 eucalyptus trees that exist along the northern property line of Memorial Park. With tree heights exceeding 100', should one or more trees fail and fall in a northerly direction across San Leandro Creek, it is very likely that Lee Avenue residences would be damaged, or worse.
