+ Flood Preparation

Know Your Number: Marietta Flood Benchmarks, provided by the City of Marietta

Know the water level that your building floods at, and know the flood pattern of your building. Understand what water levels mean for your building and how you need to respond in each case. This is different from building to building, so please equip yourselves as individual business/property owners with this knowledge.

Know Your Plan: OSHA Flood Preparedness & Response Website

On top of knowing your number, please make yourself and your employees aware of your plan for flood response, relief, etc. Know how long it takes for you to clear out a basement, for example, or how long it takes for you to shift inventory to higher ground. Again, this is different for every single business/property downtown. For some, it may take only 2 hours, for others it make take 4 or more. Please empower yourselves as individuals with this knowledge.

Know Your Risk: Ready.gov Floods Website

This page explains what actions to take when you receive a flood watch or warning alert from the National Weather Service for your local area and what to do before, during, and after a flood.

How to Use Sand Bags: Using Sandbags for Flood Protection

There is a right way and a wrong way to use sand bags. It is recommended to use a polyethylene sheet in conjunction with your sand bags; aka, put a plastic sheet underneath the bags as a barrier and stack bags on top. Also, it is recommended to stack sand bags in a pyramid shape and not directly on top of each other, loosely, and not to fill the sand bags entirely so they are malleable and their shape can be shifted. 

Note: When sand bags and sand piles are delivered downtown in the case of a flood, they will be delivered to the Parking Partners lot on Second Street.
