Narrative
The right of way appraisal process, as well as continuing developments in project design, may lead to revisions in right of way requirements. Changes may affect the right of way schedule, so the Right of Way Branch should be notified as soon as changes are identified. The Project Engineer must revise right of way requirements and send appropriate maps to Right of Way Engineering.

Narrative
Preliminary geometrics were prepared and sent to the functional units for review. Their comments were incorporated into the geometrics, as appropriate. Skeleton layouts were developed for each functional unit for use in preparing their portion of the Plans, Specifications and Estimate. The Project Engineer should add the final roadway features. These geometrics form the basis for final plan sheets.
