Subject: Rexburg Denny's - Flood Plain
Tod, Justin, and Jeff,
I’m not sure who I need to talk to about this so I’ll include all of you in this email.
As you are likely aware, the proposed Denny’s is located within the flood plain.
I received a flood plain permit application, but need some clarification on the elevation of the building.
The site plan shows the floor elevation as 4866.65.
What datum is referenced for this elevation? I’m assuming it is NAVD 88 since that is what is commonly used.
The base flood elevation at this location is approximately 4865 NGVD 1929 (or 4868.57 NAVD 88).
If my assumptions are correct, then you need to raise the building up almost 3 ft to get the floor at least 1 ft above the base flood elevation.
Could you please check the elevations/datums and provide an Elevation Certificate based on the Construction Drawings to clarify this information? You’ll need to provide a final elevation
certificate after the building is constructed.
Thanks.
