Protected trees
The ordinance applies to all property in the city except listed exemptions (single residential lots with up to two units, nurseries and tree farms, Central Business District property, recreation fields, parks and lakes, and tree loss from government or utility projects). A tree is any woody plant with a potential trunk diameter (DBH) of at least 2 inches. Specimen trees get extra consideration and must meet size and condition criteria: large hardwoods 18 inches in diameter or larger, large softwoods 24 inches or larger, understory trees 9 inches or larger. Land outside the buildable area, required buffers and landscape strips are "protected zones" under the ordinance.
