| Local Grading Ordinances | County/city grading permits, erosion control & cut/fill limits |
| Stormwater (NPDES / CASQA) | Construction & post-construction stormwater BMPs per CGP |
| Caltrans Standards | Transportation, driveway connections & encroachment permits |
| California Geological Survey | Seismic hazard zones, liquefaction & landslide mapping (Alquist-Priolo) |
Civil deliverables include site plans, utility plans, drainage calcs, and erosion control per local AHJ checklists.
| Code / Standard | Application |
|---|---|
| CBC Chapter 16 | Structural design requirements — loads, materials, systems |
| ASCE 7-16 | Minimum design loads: dead, live, wind, snow, rain, seismic, flood |
