Hi Mara,
I agree with Jonathan that keeping transportation planning boundaries on
census tract or block group lines makes many things a little simpler. Note
that just following block lines can result in transportation planning
boundaries that are cross-county or cross tracts, which can really
complicate things when you're trying to calibrate or validate against
Census data. There are many MPOs who choose not to for various local
reasons though.
Regards,
Josie

Ms. Kaminowitz:
I can tell you from 22 years of professional experience with an MPO... The
Census Bureau doesn't need (or want) to know about your MPO planning area
boundary. Urbanized areas and MSAs, CMSAs, etc are geographic definitions
only. The Census Bureau puts them out for general reference purposes, and
then other agencies like FHWA and FTA use them for funding allocations
etc., or for data gathering (like the BEA and BLS). The Census Bureau stays
out of this "political football" territory.
My organization (Metroplan in Little Rock, Arkansas) has generally kept
our transportation planning boundary on census tract lines to make data
analysis, i.e. estimates and projections, a little simpler. But that is of
course your organization's option.

*Subject:* [CTPP] drawing MPO boundaries
Hello,
We are in the process of drawing a new MPO boundary to reflect changes to
the 2010 urbanized area. There are several options being looked at for
exactly how to set the new boundary but we are not currently considering
Census geography. Does an MPO boundary get submitted to the Census bureau,
and if so are there requirements to snap it to blocks?
