Here is the presentation from the County Government, talking about three phases of APFO history, how housing units have been allocated by different regions, how the general plan is playing a role in it. We are going to have a new Howard County General Plan very soon.
I hope this new Howard County General Plan will balance growth, affordable housing, school capacity, infrastructure and sustainability much better. The county has very few land left (9%) for new development. Revitalization of some old village centers are as important as developing on new land.
Here is the presentation for your reference.
