If our project is multi-faceted and very large with multiple beds for different populations, can we apply for Round 4 for the whole budget or part of it?

BHCIP Round 4 is only available to fund the expansion benefiting the intended target population of children/youth for behavioral health services. If the project is scalable, you may be able to apply for future BHCIP rounds for other phases of your project if it serves the intended populations.
