Temporarily mark monument locations with stake and flagging.

Reconcile differences between legal description and survey.

Topographic Survey:

Establish minimum three permanent benchmarks plus one permanent benchmark for each 1.6 hectares (4 acres) within survey boundary.

Determine project site contours at maximum 300 mm (1 foot) interval.

Determine spot elevations at specified locations.

Utility Survey:

Locate piped utilities and utility structures. Identify service type, sizes, depths, and pressures.

Locate fire hydrants.

Locate wired utilities and utility structures. Identify service type, rated capacities, and elevations above and below grade.

Identify each utility authority including contact person and phone number.

Locate permanent structures within survey boundary by perpendicular dimension to property lines.

Determine structure plan dimensions, heights, and vertical offsets.

Determine projections and overhangs beyond structure perimeter at grade.

Determine number of stories and primary building materials.

Locate rightsofway and easements within and adjacent to survey boundary by perpendicular dimension to property line.

Locate project site access from rightsofway by dimension from survey monument. Determine site access width.
