What Ross requires

Required. Every Tree Alteration or Removal Permit application must include 'Justification for the removal of each tree proposed to be removed including a certified arborist's report describing the tree's condition and structure, unless waived by the town' (12.24.080(1)(d)); the Town's fact sheet (rev. 10/5/22): 'Applications for tree alteration/removal permits must include a completed tree alteration/removal application and a certified arborist report.' Development: a tree protection plan with a certified arborist's report is required where Significant or Protected trees may be impacted, mandatory for Hillside Lot and Hazard Zone Use Permits and at staff/Council discretion for subdivisions, variances, demolition, design review, grading and building permits (12.24.100). The Town Arborist reviews applications and 'If there is a conflict between arborists regarding the condition or structure of a tree, the town arborist's decision shall control' (12.24.080(4)). The Public Works Director may waive the report.

Who may write it: 'Certified arborist' means a person 'currently certified as an "arborist" by the International Society of Arboriculture, or who is a currently a member or registered consulting arborist of the American Society of Consulting Arborists' (12.24.020(2)). None; the Town retains its own Town Arborist for review

The rule the report has to address

Protected treesSpecies-neutral, size and location based. IMPROVED parcels (with a habitable structure): a 'Protected tree' is any tree with a diameter greater than 8" located within 25 ft of the front or side yard property line or within 40 ft of the rear yard property line, plus any replacement tree or tree planted in a required yard setback under a Council-approved landscape plan; a 'Significant tree' is any tree with a single trunk diameter greater than 12" anywhere on the parcel, or any tree designated to be preserved on Council-approved plans or as a condition of approval (12.24.020(9), (11); 12.24.070). UNIMPROVED parcels: any tree 6" in diameter or greater (12.24.060). Public right-of-way: all trees greater than 6" (12.24.040). 'Alter' (excessive pruning over 25% of the crown, grade changes, trenching in the root zone, etc.) is regulated like removal. 'Fire hazard' trees (fire-authority designation, a listed fire-prone species such as acacia, bamboo, arborvitae, California bay, bishop/Coulter/gray/knobcone/Monterey/Scots/Torrey pine, cedars, cypress, Douglas fir, blue gum and red gum eucalyptus, false cypress, junipers, larch, spruces, yew, or any tree within 5 ft of a house or structure) still need the permit but qualify for the 'fire hazards' approval criterion and the reduced hazardous-tree fee.

EMERGENCY: 'In the event of an emergency, when such tree poses an imminent threat to life or property, a peace officer or firefighter in their official capacity may exempt a property owner from a Tree Alteration or Removal Permit requirement in the absence of the Public Works Director. The Public Works Director shall be promptly notified of the nature of the emergency and action taken.' (12.24.070(3); same for unimproved parcels 12.24.060(3) and right-of-way 12.24.040(6)).

What the report contains

A signed PDF report. It states species and measurements taken the way the city's code requires, health and structural findings, and photographs. Where it matters, it gives a risk rating. The recommendation is written as the justification the city's code names, so staff can approve it without asking for more. For Ross that means measurements taken in diameter at 54″ above grade, the species identified against the city's protected list, the condition and structural findings, and the removal justification the code names, with replacement proposed as the code requires.

Price and turnaround

$750 to $1,250 for one to three trees, including the site visit, the findings the city requires and the replacement plan. Multi-parcel and development reports from $1,650.
