Block Outline Surveys in City of North Vancouver
Professional Block Outline Surveys in City of North Vancouver, establishing high-precision legal control networks across entire municipal blocks to anchor reliable boundary reinstatements.
When undertaking major subdivisions, infrastructure corridors, or expansive developments in City of North Vancouver, the construction phase—involving heavy machinery, deep excavations, site grading, and utility installation—poses a massive threat to physical survey monuments. To mitigate the destruction of the legal survey fabric and avoid the costly replacement of destroyed property corners, developers can leverage a highly strategic and specialized mechanism known as a block outline survey. Governed by Section 69 of the Land Title Act, this method of deferred monumentation allows a British Columbia Land Surveyor (BCLS) to establish secure control monuments before construction begins, and officially post the final property boundaries only after the heavy construction activities are entirely completed.
A block outline survey is strictly regulated by the Association of British Columbia Land Surveyors (ABCLS) Survey and Plan Rules and requires formal, prior approval from the Surveyor General. According to Rule 4-6, the boundaries under survey must be referenced by control monuments before construction and then formally posted after the site is finished. Because these control monuments dictate the future placement of every property line in the development, they must be set in a manner that achieves high absolute and relative accuracy.
To achieve this high precision in City of North Vancouver, our firm deploys a state-of-the-art arsenal of surveying equipment. During the preliminary phases, we utilize Aerial Drone Photogrammetry and Aerial Drone LiDAR to generate high-resolution 3D topographic terrain models, empowering your engineering team to design the site while we analyze the safest locations for control monuments. We then establish a primary geodetic control network using Static GNSS and RTK GNSS Receivers to integrate your project into the provincial active control system. From this framework, our crews deploy high-precision Robotic Total Stations to set durable Type 1 or Type 2 control monuments in secure, intervisible locations that are safe from bulldozers and utility trenches. When complex existing infrastructure is present, Terrestrial LiDAR (3D laser scanning) is utilized to capture a accurate, high-density point cloud of the as-built conditions, guaranteeing our control network integrates accurately with the physical reality of your site.

Our Block Outline Surveys Process in City of North Vancouver
How do we ensure accuracy and efficiency in our land surveying projects?
Research
The foundation of a block outline survey is documentary research. The BCLS retrieves historical plans, original field notes, and active title records from the Land Title and Survey Authority of British Columbia (LTSA). During this phase, the BCLS evaluates the parent parcel boundaries and prepares a formal application to the Surveyor General. This application seeks statutory permission to utilize the block outline method and must demonstrate that the control network will survive construction activities to provide a solid foundation for the final posting.
Field Work
The field work for a block outline survey is uniquely executed in two distinct phases, which directly impacts the project's timeline and scope. Initially, our crews deploy RTK GNSS and Robotic Total Stations to establish secure Type 1 or Type 2 control monuments in locations safe from construction disturbances. Once the heavy equipment has finished site grading and utility installation, our survey crews return to the site. Relying on the mathematical relationship established by the initial control network, we physically drive standard iron posts into the earth to mark the true, final property corners.
Plan Preparation
Our drafting technicians translate the highly precise 3D field data into specialized statutory plans. First, the block outline plan (such as a subdivision or reference plan) is prepared, which explicitly shows the mathematical relationship of the lands being surveyed to the controlling monuments. This plan is deposited with a Notice of Conditions of Block Outline Survey issued by the Surveyor General. After the final field posting is complete, the BCLS electronically certifies a "Posting Plan," which must be filed before the time limit imposed by the Surveyor General expires (typically one year). As your certifying professional, the BCLS guarantees that this final posting plan conforms in all respects with the original block outline plan.
