Full Breakdown
030 of the Municipal Code defines a protected 'native oak tree' as 'a living tree of the genus Quercus and species lobata, agrifolia, dumosa or hybrids thereof,' covering valley oak, coast live oak and scrub oak, species native to Ventura County's inland valleys. Unlike the chapter's mature-tree category, which only kicks in once a trunk reaches 72 square inches of cross-sectional area, a native oak is protected from the moment it's a living tree of one of those species, with no size threshold. 090. 070(B)(1)-(2).
080(A) gives native oaks a standard the other protected categories don't get: interference with 'an addition to an existing single-family detached home' is an explicit factor the city can weigh in deciding whether to grant the permit, on top of disease, structural collapse risk, or utility interference that apply to all protected trees. 100 separately bans injuring, defacing or scarring any native oak, historic tree or mature tree, a lower bar than full removal that catches bark-stripping, root damage from grading, or cutting into the trunk. 130, enforceable by the city in addition to any civil nuisance remedy.
Violations & Fines
Cutting down, removing or destroying a native oak without a permit under § 12.12.040, or injuring, defacing or scarring one under § 12.12.100, is a misdemeanor under § 12.12.130. Grading or construction that disrupts a native oak's structural roots or compacts soil within its dripline during a permitted project can also violate the chapter's development-proposal preservation safeguards in § 12.12.060.
