The color-coding of the maps, we note in passing, form the basis also of the contemporary Homeland Security alert system, thus linking histories of urban segregation abstractly to more recent patterns of national restriction.

Overview of the T-RACES demo site by project author Richard J Marciano
First Grade Areas - "A" (Green)
Second Grade Areas - "B" (Blue)
Third Grade Areas - "C" (Yellow)
Fourth Grade Areas - "D" (Red)
"A" and "B" tend to be caucasian areas, while "C" and "D" tend to represent detrimental and undesirable ethnic groups.
Excerpts of each category follow (in reverse order from "bad" to "good"):
"Red areas represent those neighborhoods in which the things that are now taking place in the Yellow neighborhoods, have already happened. They are characterized by detrimental influences in a pronounced degree, undesirable population or infiltration of it. Low percentage of home ownership, very poor maintenance and often vandalism prevail. Unstable incomes of the people and difficult collections are usually prevalent. The areas are broader than the so-called slum districts. Some mortgage lenders may refuse to make loans in these neighborhoods and other will lend only on a conservative basis."
"Yellow areas are characterized by age, obsolescence, and change of style; expiring restrictions or lack of them; infiltration of a lower grade population; the presence of influences which increase sales resistance such as inadequate transportation, insufficient utilities, perhaps heavy tax burdens, poor maintenance of homes, etc. "Jerry" built areas are included, as well as neighborhoods lacking homogeneity. Generally, these areas have reached the transition period. Good mortgage lenders are more conservative in the Yellow areas and hold loan commitments under the lending ratio for the Green and Blue areas."
"Blue areas, as a rule, are completely developed. They are like a 1935 automobile still good, but not what the people are buying today who can afford a new one. They are the neighborhoods where good mortgage lenders will have a tendency to hold loan commitments 10-15% under the limit."
"Green areas are "hot spots"; they are not yet fully built up. In nearly all instances they are the new well planned sections of the city, and almost synonymous with the areas where good mortgage lenders with available funds are willing to make their maximum loans to be amortized over a 10-15-year period -- perhaps up to 75-80% of the appraisal. They are homogeneous; in demand as residential locations in "good time" or "bad"; hence on the upgrade".
