Create websites from a csv file and folder permissions

Question

I have a csv file that contains 10 different website configurations.

I've created the script below to automate their creation. When I test the script, it runs succesfully, but I'm wondering if this is the best design to automate website creation. Is my use of the loop and the if/else statements correct?

I'm hoping someone can review and let me know if this script looks good.

I'd also like to know if there is a way to set different permissions on different virtual directories? For example, if I had a folder that is used for uploads and downloads, is there a way, through a powershell script, to set read/write permissions for that virtual directory?

Thanks!

$appPoolId = $obj.appPoolIdentity
$dotNetVersion = $obj.DotNetVersion
$port = $obj.Port

    New-Item -type directory -path $path
