Now that I have a decent start on getting my house fixed, I would
like to ask advice about what to do about my garden and lawn. My main
concern is soil remediation- my property is all sand and given the
proximity to the ocean, it's usually salty but it's got to be severe
now. We've got good drainage and we've had snow and rain since then-
will that have gotten rid of the salt and any contaminants?

But of course, salt is highly water soluable... precipitation
constantly desalinates seashores. A couple of heavy downpours will
bring your soil back to its previous/normal salinity

Maybe. It depends on the soil. If the soil is very sandy then the salt
will leach out fairly quickly, this is common in beach-side suburbs and
villages. It is possible the soil contains significant clay or organic
matter in which case it will bind salts (including sea salt). In that case
the Calcium in gypsum will be beneficial as the it will displace Sodium from
binding colloids.
