[CTPP] Effective Date of New UAs

I've got a question for FHWA folks. When do the new urban areas become effective for Federal funding purposes? The FAQ from FHWA someone referenced does not answer this question. I assume the MPO must submit its new urban area (based on the Census-defined urbanized area) to FHWA first. To give you an example, we have two suburban communities that have been added to the UA that have shared ride taxi systems funded with Federal Non-Urbanized Area Formula Program funds. Because they are now in the UA, they will not be eligible for those funds. The other example is the use of STP-Urban funding on projects located within communities that are now within UA boundary, but weren't before. When can these communities apply for such funds? Thanks in advance for your response(s). Bill Schaefer,Transportation Planner Madison (WI) Area MPO
