Description
Subtract canopyRadius from centerDistance for clearance and subtract suppliedSetback for slack.
A site clearance is a signed difference between available space and an object or allowance. A supplied setback and assumed future envelope are separate from actual legal or environmental requirements.
Subtract canopyRadius from centerDistance for clearance and subtract suppliedSetback for slack.
When to use this tool
Use Tree Grid Boundary Clearance when you need one explicit landscape clearance margin.
How to use the tool and how it works
- Enter centerDistance, canopyRadius, suppliedSetback. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read clearance, slack. Use the output convention below.

| canopyRadius | Canopy Radius | Required. Finite number; minimum 0. |
| suppliedSetback | Supplied Setback | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| clearance | Clearance | Required. Finite number. |
| slack | Slack | Required. Finite number. |

}Limitations and assumptions
- The setback and canopy radius are supplied; boundaries, legal requirements, and future growth need separate verification.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Verify current measurements, future growth, survey datums, and applicable design requirements for the site.
