About this file
This is a Clearing and Grubbing specification document (Section 31 11 00) for the Upper Makefield Township 2026 Road Program in Pennsylvania. The specification defines work requirements for clearing, grubbing, stripping and stockpiling topsoil, and debris disposal as part of roadway construction activities. The clearing work includes removal of trees, brush, vegetation, fences, walls, signs, and other obstructions within permanent and temporary construction easements and the limit of disturbance on the Owner's property. Grubbing operations require removal of stumps, roots, brush, and organic materials to a minimum depth of eight inches below the natural ground surface. The contractor must notify the Engineer at least 48 hours prior to beginning clearing work and must coordinate tree removal with the Resident Project Representative. Topsoil stripping must be staged to limit exposure and potential erosion, with staging limited to the length of trench that can be installed and backfilled in one day for utility construction. All stockpiled topsoil must be retained on-site for use in finish grading and cannot be removed or used as backfill.
The specification establishes that trees, logs, branches, brush, stumps, and debris resulting from clearing and grubbing become the property of the contractor and must be disposed of legally at locations outside the Owner's property, easements, and public right-of-ways. The contractor must obtain written agreements with property owners where debris will be deposited and submit two copies of these agreements to release the Owner from responsibility. Open burning of debris is prohibited. The contractor must protect designated trees and landscape features with temporary fencing, repair any injuries to retained plants using approved arboricultural practices, and replace any trees designated to be saved that are permanently injured or die during construction with like species acceptable to the property owner. Related work is specified in Sections 01 57 13 (Soil Erosion and Sediment Control), 31 23 33 (Excavation, Backfill and Compaction), and 32 92 00 (Finish Grading, Seeding and Sodding), with compliance required for Pennsylvania Act 287 (1974) as amended by PA Act 121 (2008) regarding utility relocations.
