126.4 Attachments to the Location Study

The narrative portion of the study is followed by:

• Estimate sheets, if the estimate is not carried in the body of the study (estimate is as complete and accurate as possible, including right of way, utility and construction costs broken down into sections that correspond to the description of the alternates).
• General location map (copy of the county map showing the entire project limits on one sheet).
• Typical section.
• Any special drawings that might be needed.
• Location sketch (aerial mosaic, USGS quadrangle sheets, etc.) showing the various alternates considered and any constraints, labeled consecutively.
• Results of environmental scoping, including wetlands, historic sites, hazardous waste, threatened and endangered species habitat, and archaeological sites are identified on the location sketch. Archaeological sites are not located specifically since that information is sensitive and not to be publicized.
• A safety assessment.

In order to standardize color-coding of the exhibits in the study, red is used for the recommended location, green for the first alternate, and blue for the second alternate. Brown is used for any previously approved location and yellow for existing MoDOT routes. Where stage construction is contemplated, the second stage work is shown as a dashed line. Work materially beyond the limits of the program is also shown with a dashed line, using a different length dash than for stage construction. Color-coding is not required; different line symbols may be used. It should be easy to identify the various alternates either by color or by distinctive symbols.
