Tree Table

Builds the landscape-ordinance tree preservation / mitigation table from the survey: parses species and DBH out of tree-point descriptions, marks trees inside the limits-of-disturbance polylines as removed , classifies protected vs specimen, and computes the replacement-tree count.

Builds the landscape-ordinance tree preservation / mitigation table from the survey: parses species and DBH out of tree-point descriptions, marks trees inside the limits-of-disturbance polylines as removed, classifies protected vs specimen, and computes the replacement-tree count.
Trees inside the closed LOD polyline count as removed; protected/specimen inches drive mitigation. LIMITS OF DISTURBANCE (removed) OUTSIDE LOD = preserved TR-OAK-24 → 24" OAK protected TREE 34 PINE → 34" SPECIMEN (ERROR) 18 MAPLE → below 24" 36IN LIVE OAK → preserved TR 22 GUM → preserved Mitigation count = ceil(removed protected in × ratio ÷ repl. caliper) protected ≥ 24" DBH   specimen ≥ 30" DBH exempt species dropped from the count
LOD polyline *LOD*, *DISTURB*, *LIMIT*   Specimen removed (ERROR)   Protected removed (WARNING)   Preserved (outside LOD)   Below threshold

What it does

  • Parse: trees are COGO points whose description matches the patterns and parse, first number = DBH inches, remaining words = species (24 OAK, TREE 30 PINE, 36IN LIVE OAK, TR-OAK-18 all work).
  • Removed vs preserved: trees inside any closed polyline on the LOD layers count as removed; the rest preserved.
  • Classify: protected (≥ 24" default), specimen (≥ 30"), exempt species list dropped.
  • Mitigation: ceil(removed protected inches × ratio ÷ replacement caliper).
  • Flags: specimen-in-LOD = ERROR (individual approval), protected-in-LOD = WARNING (mitigation).
  • No closed LOD polyline found → every tree reports preserved (command line says so).

Settings & outputs

  • Tree descriptions: comma wildcards (default *TREE*, TR *, TR-*); noise tokens (TREE/TR/IN/EX) configurable in settings.json.
  • LOD layers: default *LOD*, *DISTURB*, *LIMIT*.
  • Thresholds + mitigation: protected/specimen DBH, ratio, replacement caliper, verify against the governing ordinance, defaults are placeholders.
  • CSV (always): full inventory + per-species summary + mitigation totals.
  • AutoCAD table (optional): species summary + mitigation line at a picked point.
  • Palette: specimen/protected removals, double-click to zoom. Settings at %APPDATA%\VDC\TreeTable\settings.json.

When to use it

  • Producing the tree preservation / mitigation table for a landscape or land-disturbance submittal.
  • After every grading revision - the LOD moved, the counts moved.

How to run it

  1. Run VDCTREETABLE; confirm the description patterns, LOD layers, thresholds, and mitigation ratio; click OK.
  2. The tool parses every matching COGO point, classifies removed vs preserved by the closed LOD polylines, and totals mitigation.
  3. Pick a point for the species-summary table (or skip); the full inventory CSV lands in the drawing's VDC Reports folder; specimen/protected removals show in the palette.

Options

  • Tree descriptions: comma-separated wildcards (default *TREE*, TR *, TR-*); a match must also contain a DBH number.
  • LOD layers: closed polylines on these layers are the disturbed area (default *LOD*, *DISTURB*, *LIMIT*).
  • Thresholds + mitigation: protected/specimen DBH, replacement inches per removed inch, and replacement caliper - VERIFY against the governing ordinance.

Watch out for

  • The default thresholds/ratio are placeholders, not code citations - jurisdictions differ by species class; set them per the ordinance before submitting.
  • Specimen removals flag as ERRORS because they typically need individual approval, not just mitigation inches.
  • No closed LOD polylines found = every tree reports PRESERVED (the command line says so) - check the LOD layer patterns.
