Land Surveyor in Larkspur

Larkspur runs from redwoods to bay fill in about two miles, and the survey conditions change just as fast. Baltimore Canyon and Madrone Canyon are narrow, steep, and shaded, with 1900s summer-cabin lots on lanes that were never widened, retaining walls holding up the driveways, and creek setbacks in play on nearly every remodel. Downtown along Magnolia Avenue is an intact older grid where record lines and long-standing fences have had a century to part company. At the other end, Larkspur Landing was built on former quarry and bay-margin ground: the Golden Gate ferry terminal, Marin Country Mart, and the SMART station that opened in 2019 sit on low, flat land where FEMA flood zones and NAVD88 elevations govern what gets built and how it is documented. Corte Madera Creek drains the whole Ross Valley past the edge of town.

Neighboring Corte Madera repeats the pattern in miniature, with hillside lots above and the Town Center and Village shopping districts on filled ground beside Corte Madera Marsh. We handle both ends: monument recovery and boundary retracement on canyon lots, datum-referenced elevation work along the flats, and Records of Survey filed with Marin County. Our terrestrial laser scanner is the practical answer on the canyon parcels, where a conventional topo means dragging a rod up a 30 percent slope under redwood canopy; one visit captures the ground, the walls, the trees, and the house, and we filter vegetation in processing to deliver a true bare-earth model with contours and a DWG base map. Commercial and mixed-use buildings get the same instrument as scan-to-CAD as-builts and BIM-ready models.
