How to use this result
Use measured paved area rather than the property area. Keep drainage, curbs, accessible routes and professional work visible instead of burying them in the square-foot rate.
Surface allowance
The tool applies an editable planning rate by surface and a multiplier for base conditions.
Complete-site additions
Drainage, curbs, signs, markings and professional work are added separately so omissions are easier to see.
Important: This calculator does not design pavement thickness, grades, drainage or accessibility. Obtain site-specific civil, geotechnical and local approval review.
