	This work consists of grading work necessary to bring a roadway to required grade and cross-section, allowing reasonable tolerances for economic reasons. When performing Design field checks, consider the availability of material needed to complete the grade. The cost for the different methods for completing the grade should be reflective of the effort required.

	Linear Grading, Class 1 can be used as a unit of measurement for grading approaches on plans for all systems within the limits of Class 1 and Class 2 Linear Grading. Measurement will be made to the nearest 10 ft. for each facility and totaled to the nearest 100 ft. If grading quantities exceed Class 2 limits, Volume Grading is required and specified for approach construction. No attempt is made to adjust volume grading quantities where linear grading is used for grading approaches connecting to sections of the main roadway being graded by volume.
