Verified condition
Slope and grading
Sloped parcels change how a building meets the ground. Cut and fill quantities, retaining walls, driveway gradient, drainage discharge and construction access are decided together, not one at a time.
How does a sloped lot change a project here?
On a slope, the foundation approach, retaining walls, driveway gradient, drainage path and construction access are a single connected decision. The practical first step is confirming slope percentage, mapped geologic conditions and the local grading permit threshold for the specific parcel.
How to verify it
Confirm the parcel's slope percentage, any mapped geologic condition, the grading permit threshold in the municipal code and whether a soils or geotechnical report is required before design is fixed.
