Clearing and grubbing is estimated during the design field check and, in conjunction with aerial photographs if available, consistent with the method of measurement given in the standard specifications. The standard specifications establish the size of trees and stumps that qualify for payment as clearing and grubbing.
Roadways designed with clear zones are cleared at least to the minimum clear zone width. Use other roadway exceptions to decrease the cost of roadside maintenance and to improve the appearance of the completed facility. Clearing is excepted at the top of deep cuts, the bottom of high fills, in areas not conveniently accessible to maintenance equipment, in areas where the natural growth of trees and shrubbery will blend with adjacent areas and at all other locations where natural trees and shrubbery will improve the appearance without detracting from the service of the completed facility. Clearing exceptions can be used to control at interception and roadway ditch outlets. Areas that are not to be cleared are outlined on the plans and noted as "No Clearing" or "N. C." in accordance with Sample Plans. This area should provide sufficient clearance for equipment to construct items such as interception ditches and levees at the top of backslopes or at the bottom of fillslopes. When the entire surface of the right of way is not to be cleared, the following general note is included on the first plan-profile sheet:
- "Areas noted 'No Clearing' or 'N. C.' on the plans are not to be cleared of trees, undergrowth, brush, grass, weeds or natural rock formations."
The clearing and grubbing quantity is estimated and pay items in acres [hectares] are included. The quantity of acres [hectares] is to be placed on the Summary of Quantities 2B sheet.
