I climbed there yesterday. They already started clearing space for the new development around the current "parking lot." Not much has changed as of yet, and it's still free.
If you're going to be in the area Sand Rock is a great place to climb. Has pretty decent routes (for this far South!) and something for everybody. It's still no backcountry experience, but I don't think it's as dirty as it used to be.
There's nothing on SP (that I'm aware of) but mountainproject.com has a decent list of routes so you can find a few climbs without a guidebook.
