... I would refuse any evacuation order. I can shut off gas and power just fine myself (assuming I didn't actually smell gas at the time of course). I would camp out in the yard if I had to, ...

And once the danger of neighboring houses bursting into flames had passed
(a while after the lights went off),I'd shelter inside the house,

... and let them in with a key if they didn't believe me it was off (I am sure they would not believe me).
No reason for them to enter the premises if there's an outdoor valve.
I wouldn't out myself by being seen by the cop/gas-guy/locksmith team.
