Questions
Lot contour map: what people ask
Is a LiDAR contour map a topographic survey?
No. In California, determining the contour of the earth's surface for others is land surveying under Business and Professions Code 8726. A LiDAR map helps you plan; a permit that asks for a topographic survey needs a licensed surveyor.
Do I need a stormwater permit for my grading?
Federal rules cover clearing, grading and excavating that disturb one acre or more, including smaller lots in a larger plan of development. Your city or county may have its own grading permit at smaller sizes.
Can I check the lot's flood zone too?
Yes. FEMA's free FIRMette tool prints a full-scale section of the official flood map on a home or office printer, and FIRMettes can be used in all aspects of the National Flood Insurance Program.
