Penelope,
I would like to reiterate what others have
said regarding TAZs with less than 600 residents. Most MPOs will have
many zones below this threshold (e.g. airports, parks, shopping centers,
corporate campuses, future growth areas, etc). The software should allow
users to enter comments for TAZs that do not meet this threshold. These
comments should be included in the report that is generated for the Census
Bureau’s review. A similar feature was included in the PSAP
software.
Section II.A implies that counts of
workers at their workplace location from the 2000 Census are (or will be)
available at the Census Block level. Can you confirm this? Will ACS
data at the workplace location (also) be available by Census Block?
Section III.I states that TAZ numbers may
be 8 characters long. Is this 8 character limit in addition to a state
and county code. We intend to number our 2010 TAZ’s with a 2-digit
state code, followed by a 3-digit county code, followed by 4 digits to identify
the TAZs in each county. (We would like to use FIPS codes for state and
county). This would result in a 9-digit TAZ number. We are a
bi-state agency, but even single-state MPOs may want to include traffic zones
from outside their jurisdictions as external stations and could benefit by incorporating
state and
Thank-you

Subject: [CTPP] Memo to Census
Bureau regarding delineation business rules
Hi All,
The Census Bureau asked us to refine this document to help them
with their software development effort. There was a three step process
and this is step two. Step three will be the formal version of the
attached memo, due to Census Bureau in early 2010. At this time we are
seeking input on this memo for the formal version. Please reply directly to me with your comments.
Please reply by January 8th,
2010
Thanks!

It's just as bad to not make a plan as to blindly follow the
one you already have.
