Road Surveys in the Sea to Sky

Whether designing new transportation infrastructure, dedicating public access for a major municipal subdivision, or resolving historical access rights in the Sea to Sky, the establishment and surveying of roads is an intensely regulated legal process. Navigating the complex spatial and legislative requirements demands professional geomatics engineering, strategic foresight, and high statutory authority. In British Columbia, the measurement of land to determine, locate, define, establish, or re-establish boundaries is legally defined as the "practice of land surveying" under the Land Surveyors Act. Therefore, only a commissioned British Columbia Land Surveyor (BCLS) holds the exclusive statutory right to determine the legal boundaries of transportation corridors and certify the associated survey plans.

The classification and creation of road corridors are governed by overlapping provincial statutes. Under Section 1 of the Land Act, a "public road" is defined as a portion of Crown land designated or indicated as a road on a plan of survey made under the Act, including road and walkway allowances. Conversely, a "highway" is defined under Section 1 of the Transportation Act and encompasses public streets, roads, trails, lanes, and bridges. Highways can be legally established through several mechanisms: the deposit of a subdivision, reference, or explanatory plan under Section 107 of the Land Title Act; the expenditure of public money under Section 42 of the Transportation Act; a common law dedication; a historical Gazette Notice; or by being depicted in a specific colour on a Crown grant tracing.

To conduct these specialized surveys, our professionals must adhere to Part 6 of the Association of British Columbia Land Surveyors (ABCLS) Survey and Plan Rules, which governs highway, public road, and railway surveys. For highway surveys exceeding one kilometre in length, our crews must deploy highly specific monumentation frameworks, utilizing either a boundary system or a centre line system to systematically mark the corridor. Furthermore, the intersections of the new highway with existing surveyed boundaries, water bodies, and other travelled ways must be rigorously determined and documented.

To capture the complex topography and boundary evidence associated with road surveys in the Sea to Sky with high absolute and relative accuracy, our firm deploys an professional arsenal of cutting-edge geomatics equipment. During the preliminary route planning and reconnaissance phases, we utilize Aerial Drone Photogrammetry and Aerial Drone LiDAR to penetrate dense vegetation and generate accurate 3D topographic terrain models. We establish a highly robust primary survey control network by occupying points for extended durations using Static GNSS Receivers, integrating the corridor seamlessly into the provincial active control system. From this primary network, our survey crews utilize RTK GNSS measurements to rapidly navigate the site and capture boundary evidence with centimeter precision in open-sky environments. However, in dense urban corridors, deep ravines, or under heavy tree canopy where satellite signals are obstructed, we deploy high-precision Robotic Total Stations to run closed-loop traverses, ensuring absolute statutory compliance. When a road corridor involves intricate infrastructure, bridges, or complex retaining walls, Terrestrial LiDAR (3D laser scanning) is utilized to capture a high-density 3D point cloud of the as-built conditions, guaranteeing that all physical elements are accurately mapped relative to the legal boundaries.
