Note that Bloomingdale's 25-acre McMillan Sand Filtration site in fluorescent green on the map below is marked as a Planned Unit Development (PUD).
Planned Unit Developments are a big part of building in DC. Here's an explanation of what those are.
When it comes to development, there's often tension between what's practical or ideal and what the zoning rules at a given site allow. One tool available to builders in DC is called a Planned Unit Development. PUDs allow flexibility in the rules, and since they're happening all over the city, it's worth understanding what they are and how they work.
What is a Planned Unit Development?
A .. PUD gives developers more significant zoning relief. This can come by way of allowing a building to be taller or denser than what the zoning code says is allowed, or building a residential or commercial building in space that's zoned for industrial.
