Description
Subtract adjacentSurfaceLevel from curbTopLevel for signed reveal.
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 adjacentSurfaceLevel from curbTopLevel for signed reveal.
When to use this tool
Use Curb Reveal Level Pair when you need one explicit landscape clearance margin.

}Limitations and assumptions
- Levels need a shared datum and unit; this does not establish drainage, trip safety, accessibility, or construction compliance.
- 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.
