The Consultant shall prepare line and grade studies, which will include but are not limited to the following: Establishment of design criteria. Develop typical roadway sections. Develop horizontal geometry. Develop vertical geometry and set minimum roadway grade. Identify major drainage structure locations. Establish approximate required right-of-way (ROW) limits. Develop a list of impacted improvements, including potential utility conflicts. Line and Grade Report. This analysis shall encompass more detailed variables which should include but not be limited to the following categories: 2.2 Design Criteria The Consultant shall review design criteria from the previously prepared Environmental Document to determine if any modifications are necessary based upon currently established DOTD design criteria and will update the design criteria appropriately. The Consultant shall establish the design criteria which will include design class and design speed, lane widths, minimum horizontal curvature, maximum side slopes, horizontal and vertical clearances, and maximum roadway guide. The Consultant shall prepare a Table of Design Criteria to be included in the document. The design criteria will be used in developing the horizontal and vertical alignments. The design criteria will be based on latest official DOTD Design Road Design Manual and American Association of State Highway and Transportation Officials (AASHTO) for design speed and functional classification, and on recommendations from DOTD...
