Most grant funding is for a specific deliverable not a PDA designation. These funding requirements would included in an agreement before any funds are awarded. For example. this deliverable could be a Specific Plan or a bike lane.
For OBAG grants, funding is designated for areas with a PDA. These are the main grant funds used for a community-driven planning process for a PDA. While each new annual round of grants will have its own requirements, past cycles fund a specific deliverable in a PDA. Once the funding is awarded the same PDA boundaries or designation has not been required. In most cases, changes to a PDA boundary show a successful community-driven planning process.
