Site

Trenching: If trenching is required then confirm that property does not sit in a flood zone, always use the FEMA's National Flood Hazard Layer (NFHL) Viewer to confirm.

1) If not in a flood zone, then nothing else is required.

2) If it does fall within a flood zone, then our trench needs to be outside of that flood zone, and we need to show the flood zone on the site plan.

Existing Generator(s): If existing generator is present, AHJ will request additional details that need to be provided.

1) Size in kW

2) Manufacturer

3) Location of Generator on Site Plan & Placard
