A substantive proffer

According to the Washington Business Journal story "JBG to donate $4 million toward developing D.C. parks," this is a required proffer--not a donation--as part of a Planned Unit Development zoning matter in SE DC.

PUDs are the only zoning matter that tend to require "community amenities," based on the value of additional square footage received by the developer over "matter of right" square footage that could have been built through the normal process.

We need to find out what the value calculation was. Not that anyone keeps track, but this appears to be one of the highest community amenity awards I've run across over the past few years. Most are so paltry as to be laughable.
