Systems and method are provided to protect devices from damage due to floodwaters. For example, a system includes a floating platform assembly, an apparatus securely disposed on the floating platform assembly, first and second platform retaining members connected to the floating platform assembly, and first and second vertical support members disposed on opposite sides of the floating platform assembly. Upper ends of the first and second vertical support members are connected to an outer sidewall of a dwelling, and bottom ends of the first and second vertical support members are fixedly secured at ground level. The first and second platform retaining members insertably receive the first and second vertical support members, respectively. The first and second platform retaining members are configured to slide along the respective first and second vertical support members when the floating platform assembly vertically rises and lowers in response to a changing level of floodwater.
