The drone video of the CRS-10 1st stage landing doesn't seem to chow any work being done for the next 2 landing pads.

I noticed that too.

So either they're:
1. starting clearing the padspace after the CRS-10 landing
2. Realizing they'll never launch FH during the nesting period
3. somehow landing the boosters on the center pad together, or,
4. (Extremely unlikely) going expendable on the boosters
5) Lease additional LC pads nearby rather than disturb virgin brush cover

6) Waiting for all necessary approvals and for Scrub Jay's to finish nesting?

This is all assuming the Scrub Jays don't suffer schedule delays of course.

Or if they work off Elon time, if so they'll stop nesting near 2030  8)

How close are the landing pads actually expected to be? You would think that >500m would be necessary to keep a safe navigation distance and prevent one RUD from taking out the second booster.

Launches attended: Worldview-4 (Atlas V 401), Iridium NEXT Flight 1 (Falcon 9 FT)

I did some rough approximation in Google Earth, the landing pads all appear to be about 1,000 feet from each other. The top yellow line matches to the top measurement box, the bottom yellow line matches the bottom measurement box. The red line is a copy of the top yellow one, rotated and aligned with the center of the south pad. As you can see, the north pad clears that red line by a little, confirming (in the loosest sense of the word) that all the pads are about 1,000 feet away from each other.

Land clearing has begun to the north, per May 16 Planet imagery update:

The consecutive successes of SpaceX recovering every booster they set out to do since they finally figured it out suggest SpaceX might not even leave enough margin for a RUD destroying other boosters. Recovery isn't a critical mission. They can always build more boosters.

If a booster thinks it has significant damage its better to abort a landing and crash into the ocean or trigger FTS instead of landing and risking damage to ASDS or another booster.

I think their sole concern is the rocket engine blast between boosters don't topple/blow landed/landing stages away in normal conditions.
So far the SpaceX way of navigating boosters for landing has achieved such uncanny precision, that they could end up just taking whatever rocket blast/exaust safe distance, increase that by 50 or 100% and be done with it.
