One of the Canadian Coast Guard’s (CCG) mandates is to establish, maintain and operate a network of aids to navigation to allow mariners to safely navigate Canadian waters. These aids must be visible at all times.
To ensure the visibility of these aids, we did field surveys to establish a corridor within which vertical non-obstruction clearance is required. This corridor allows us to accurately identify any obstacles.
The purpose of this work is to clear the visibility corridor and improve marine safety in the Sainte-Anne-de-la-Pérade area.
The contractor must prune the trees located in the non-obstruction corridors to improve visibility of the the above-mentioned range shown in Appendix A. These trees, which are identified with paint and/or tape, are of various species and sizes. They must be pruned to the correct cutting height depending on the sector located in the visibility corridor (900 to 1100 trees to be pruned in total). The geographic coordinates, tree species and cutting heights, identified by sector, are illustrated in detail on plan No. QE6086070-A101-CL in Appendix B.
