Attribute Definition:
The foundation is defined as the roadbed under the surface and base. Its condition is evaluated on the basis of evidence which indicates poor support for the roadway surface structure such as the following: 1)Insufficient grade elevation to prevent groundwater from destroying surface stability or provide for adequate snow removal. 2) subsidence of a section of road below adjacent sections. 3) Sideslopes which are too steep or seriously gullied. 4) Surface and base failure with poor subgrade material evident in shoulders and sideslopes. ... The foundation condition rating should reflect the frequency and extent or poor foundation. As to: 1)Generally poor foundation for the entire road section requiring complete reconstruction or the roadbed-low rating or 2) A localized condition which can be corrected with relatively low cost outlay.

State Segment Sequence- On secondary roads this field will be the Section number plus the Road number with leading zero's if applicable. Section 01 and Road Number 02 would be coded 0102. For primary, municipal, and institutional roads, the sequence numbers are used to progressively order road segments by route within a county. The sequence numbers begin at the west or south county line or at the beginning of the route. Breaks in road sections are made on a route at the following points: Intersections with other roads, Intersections with corporation lines, a change in function code, a change in type section, a change in interstate traveled way, interchange ramps, a section line, a change in rural-urban lines, change in surface type,surface width or should width, a traffic volume change, a change in FHWA route number, a change in the maintenance contract on primary roads, a parking change, a rating change of two or more points, a change in federal functional class. On institutional roads, the sequence numbers begin at the entrance to the institution or at the junction of another road in the institution and does no follow the west and south guidelines.
