The uniqueness of Sonoma County inspires us to seek sustainability in all aspects of land development. Sensitive and mindful design should inform all decisions concerning our impacts on the environment.

“All good things are wild and free.” ― Henry David Thoreau

The surveyor has traditionally been an agent of destruction to the natural world, his footsteps being closely followed by the bulldozer and the parking lot. Our practice seeks a new paradigm, one that treads more gently on planet earth.

Ambiguity in the position of property lines can create mistrust and friction between neighbors who, once the issues are clarified by a land survey, can co-exist without conflict. The surveyor is ethically and professionally bound to adjudicate property boundaries fairly and impartially, regardless of who pays the fee.

Any previous errors or discrepancies that are discovered by the survey must be resolved using time-tested legal principles that are fully disclosed in a map that becomes a matter of public record.
