4 foot Generator HVAC pad

[workinallthetime]

We are building a new home in a flood plane, before you say 登h gosh I have lived on or maintained this property for 40 years and I have seen the worst flooding to hit the area. With this in mind we are building a coastal style home where the ground floor is the garage and has high concrete walls way above the flood zone. However I must raise the gen and hvac pad to keep them out of a possible flood. I do not want the pad physically attached to the house because of vibrations when it does need to run. I am thinking a dirt pad with timber walls possibly out of 6x6 pt lumber.
Any thoughts?

Yeah, no! Wood floats remember. (Assuming you are setting the wood on grade) you need to build every thing as if it's going to reach the 100yr flood elevation. If I needed to rely on a generator (why else would you install it?) I'd be taking every precaution to make sure it was safe and secure when I needed it. If I missed something please correct me.

Agree wood wood floats and wood in contact with earth will eventually rot out. My contractor suggested just a earth pad, that’s a lot of earth and I can’t imagine it will look that good. I would need to create a 4 foot pad for the units and slope it to shed water and mow the area. This is why I am toying with some sort of enclosure, perhaps concrete walls?

Clearly this is much lower to the ground than you are probably thinking, but the idea seems to be on the path of what you could do. Elevate it higher with bracing for the legs and solid posts in the ground.

Generator Elevated platform

I like it, might use piers with the post on top to eliminate ground contact. I have several large power poles and bridge beams that may serve as supports once cut to size.

I would set posts and built it on a platform. Then place wood fence panels around it for looks and to help a little with noise. Make it large enough you can walk all the way around it inside

How tall of a dirt pad? I was picturing water being 6 foot deep and the pad being 6 inches high. I like the elevated platform with a walkway around it.

Pad at 4 feet will be 3 feet above the 100 flood elevation, elevation of the 1st living space will be 9 to 10 feet above the elevation. Power goes down on a regular basis in the area thus the need for the gen.
Gen set / hvac deck I’m thinking is the way to go.

Don't forget, it didn't happen if there are no pictures. ..

Sonotubes (with rebar cages), and build PT deck on top.
