Hillside Surveys for Sloped & Canyon Lots

Sloped lots demand precise terrain data. We map the grade, locate boundaries, and provide the topographic detail your architect, engineer, and the city need for hillside design.

Tell us what the city, county, architect, or engineer requested — we'll help confirm the right survey for your project. Call now to discuss it.

What is Hillside Survey?

A hillside survey combines accurate topography with boundary work so you can design and permit on sloped, canyon, and foothill property. Southern California's hillside neighborhoods bring grading, drainage, retaining-wall, and setback questions that flat-lot surveys never face. We capture the terrain in detail, locate your property lines on uneven ground, and deliver mapping your design and grading teams can rely on.

Frequently asked questions

What makes a hillside survey different from a standard survey?

Hillside work focuses on terrain: dense contours, spot elevations, slope, drainage, and existing walls, plus boundary location on uneven ground. This detail drives grading plans, retaining walls, and hillside-ordinance review.

Can you combine slope-band analysis with a hillside survey?

Yes. Many hillside jurisdictions require a slope-band (slope-density) analysis to determine buildable area. We provide it alongside the topographic and boundary survey.

Do you use drones for hillside mapping?

Where access and conditions allow, drone-based aerial mapping can efficiently capture large or steep terrain, which we combine with ground survey for accuracy.

How much does a hillside survey cost?

Steepness, vegetation, lot size, and the detail your design requires all affect price. Request a free estimate and we will scope your specific lot.

Licensed Surveyor Oversight

Survey work is completed by, or under the responsible charge of, California-licensed Professional Land Surveyors. When a stamped survey is required, the final deliverable will identify the responsible licensee for that project.
