1) Since there is no horizontal or vertical design, are slope stakes needed? Is it necessary to verify cross sections? 2) Is it necessary to stake clearing limits when the it is only 3 feet from edge of road. 3) Is it necessary to stake final grade, when there is no design?

Where existing alignment and grade constitute the initial field control, it is not necessary to verify cross sections, stake clearing limits or final grade. Station stationing is required.In sub excavation and culvert replacement areas addition survey and staking is required as per 152.05
