This is a lie on multiple levels:

1. 40% was the percent of market-rate units, not total, which is the actual definition of affordable. It ended up around 35% of total units.
2. Many units were also available to renters making up to 150% of AMI, which isn’t considered “affordable” for rentals.
3. It wasn’t “any new development” it was two developments.
