Any trees located below the top of slope and within the upper one half of the drain bank, that are larger than 200mm in diameter shall be flagged for assessment by the Engineer prior to their removal. The Contractor shall take precautions to prevent damage to any trees, shrubs, etc. that are designated to be protected and saved. The replacement and/or repairs of damaged trees shall be undertaken by a qualified person, approved by the Engineer.
All brush and trees removed by the Contractor shall be disposed of by piling on City Owned property in proximity to the drain.
Upon completion of the work, the contractor shall trim any broken limbs or branches from standing trees. The proper disposal of all brush and trees removed during the course of construction shall be to the satisfaction of the Drainage Superintendent and Engineer.
4.0 Excavation and Trucking of Excavated Material
No excavation of the channel is recommended at this time. The following specification is provided in the event that excavation is required as part of future maintenance.
OPSS Form 206 (MUNI) and City of Windsor Standard Specification S3, shall apply and govern except as amended or extended herein. The channel shall be excavated to within 50mm of the design profile. The remainder of the channel cross-section shall be constructed to within 50mm of the design section. Over-excavation of the drain bottom will be corrected using compacted site selected material as approved by the Engineer and at no cost to the Owner. Over-excavation of the drain bank beyond the specified tolerances shall require that the bank be repaired in accordance with a repair detail prepared by a Professional Engineer (retained by the Contractor). The repair detail shall be subject to review by the Engineer. The full cost of the repair, including the fees of the aforementioned Professional Engineer, shall be borne by the Contractor.
