Permit Review Context
What matters when scoping Grading & Drainage Plans
Grading and drainage drawings become important when a project changes ground elevations, adds impervious area, alters runoff paths or requires erosion-control information. The required level of detail depends on the site, local stormwater rules and the amount of land disturbance.
We use these topics to frame the drawing scope, but the final submittal requirements are set by the city, county or other reviewing authority for the project address.
