Comment(by mikepease):

 Hi, Regina.
 Long time no talk-
 I had a couple thoughts on this "squishing" recently.

 1) Parcel data is becoming more available.  Minnesota now offers free
 access to the Twin Cities metro parcel data with geometry for all
 properties.  The tiger geocoder potentially could look for parcel data
 when available for a given area.

 Or another approach is to clean up the Tiger address ranges.

 2) Cross-reference the to/from address ranges for each street with the US
 Postal Office database.  There is a service I've experimented with that
 provides a web-based interface to the USPS address database.  It is:
 http://smartystreets.com

 It's fast and cheap.  For non-profits, I think there is a free option.
 You send it a list of addresses and it sends back the list with post
 office codes appended that signify things like if it's a real address.

 I could imagine writing some code to automate this cross referencing the
 millions of street segments in the Tiger database.  The result could be to
 find out the REAL min and max address ranges for every block.

 Also, I've spoken to the management of this small business about a month
 ago.  They were in the process of enchancing their limited geocoding
 capability.  They geocoded down to a zip+4 level, not to the street.
 Perhaps there is a potential for a partnership between you and them?
