Just read through the 16 pages here (don't tell my boss!) and a few things to add (still!)
Real Estate. Touched on in page 12, but 20015 is the second most expensive zip code in the whole DMV now (
https://www.washingtonian.com/2019/04/15/great-places-live-100-priciest-zip-codes-washington/) If you don't think that's directly because of the Lafayette renovation, you're not paying attention to local estate trends.
DMV Demographics. MoCo schools are having their own capacity crisis, and in Virginia, #Amazon. Who knows what that will do to the wider area!
Free pre-k. Free Pre-K keeps affluent families in DC. Echoing what folks have started posting - even for 'affluent' families, it's huge! Without free pre-k, we likely would have bought in the 'burbs instead of the city, since we have more than one kid, and we were already lotteried into a HRC.
I'd like to see DCPS + the charter board merged so there's central (and new, smart) leadership. The savings on redundant admin staff along should make it worth it.
