Summary
Once a Santee property carries a required fuel modification zone under WUI Code Section 603.5.2, Section 603.5.6 makes the owner or occupant responsible for maintaining that defensible space year-round, including removing dead vegetation and keeping tree canopies clear, and lets the code official inspect and order corrective work.
603.5.6 Maintenance of Fuel Modification. Any person owning, leasing, controlling, operating or maintaining a building or structure required to establish a fuel modification zone pursuant to Section 603.5.2, shall maintain the defensible space. The code official may enter the property to determine if the person responsible is complying with this Section. The code official may issue an order to the person responsible for maintaining the defensible space directing the person to modify or remove nonfire-smart vegetation from fuel management zones, remove leaves, needles and other dead vegetative material from the roof of a building, maintain trees as required by Section 603.5.7, or to take other action the code official determines is necessary to comply with the intent of Sections 603.5 et seq.
Full Breakdown
Section 603.5.6 of Santee's Wildland-Urban Interface Code amendments puts a continuing maintenance duty on anyone owning, leasing, controlling, operating or maintaining a building that is required to carry a fuel modification zone under Section 603.5.2. The code official can enter the property to check compliance and can order the responsible person to remove nonfire-smart vegetation from the fuel management zones, clear leaves, needles and other dead vegetative material off the roof, keep trees pruned to the standard in Section 603.5.7, or take whatever other action the intent of the fuel modification sections requires.
Section 603.5.6.1 sets the tree standard the maintenance duty must meet: mature tree crowns inside a fuel modification zone need at least 10 feet of horizontal clearance if the species is fire-smart, or 30 feet if it is not, and limbs must be pruned to a vertical clearance of three times the height of the lower vegetation or six feet, whichever is greater. Table 603.5.6.1 sets the required distance between mature tree canopies by slope: 10 feet on ground of 20 percent slope or less, 20 feet on 21 to 40 percent slope, and 30 feet on slopes over 40 percent.
Dead wood and litter must be regularly removed from trees, and ornamental trees are limited to groupings of two or three with the canopies of each grouping kept separated by that same slope-based table.
Violations & Fines
An owner who ignores a code official's order to restore brush clearance or defensible space can be charged with a misdemeanor under Section 109.3.7, carrying a fine of up to $1,000, up to ten days in county jail, or both, with each ten-day period the violation continues after notice counting as a separate offense.
