<br />~\,\NESOt, <br /> <br />\~tJ <br /> <br />STATE AID FOR LOCAL TRANSPORTATION <br />Design Element Variance Justification Checklist <br /> <br />April 2007 <br /> <br />A request for a variance to the design elements required by State Aid Operations Rules <br />Chapter 8820 should contain the following as applicable: <br /> <br />1. As required by the Rules: a certified resolution from the responsible city council <br />or county board which identifies the project by location and termini, cites the <br />applicable Rule and chapter, cites the standard for which the variance is <br />requested, and describes what is proposed in lieu of the standard. <br /> <br />2. Location map and typical section (in-place and proposed). <br /> <br />3. Describe adjacent land uses (agricultural, residential, commercial, etc). Describe <br />effects of designing in accordance to Rule versus proposed non-standard <br />element on adjacent properties, pedestrians, bicycles, motoring public, and <br />emergency vehicles. <br /> <br />4. Define the critical design element involved (i.e. not "Design Speed"): <br />horizontal alignment (radius or degree of curvature), vertical alignment, grades, <br />lane width, shoulder width, bridge width, structural capacity, stopping sight <br />distance (horizontal and vertical), cross slope, super-elevation, clearance <br />(horizontal and vertical). <br /> <br />5. Estimate the cosUimpacts to construct to the standard, the cost to build to the <br />proposed element, and information that logically explains why the particular <br />proposed design was chosen. For instance, if the radius and sight distance for a <br />horizontal curvature is proposed at 35 mph instead of 55 mph, include <br />cosUimpacts for 50 mph and 40 mph radii and sight distance. <br /> <br />6. Include available accident data in detail that indicates the resulting damage <br />(property damage/injury/death), contributing causes, and location. <br /> <br />7. Include existing and projected traffic counts. <br /> <br />8. Include legal, posted, and/or safe speed of abutting roadway sections. <br /> <br />9. Indicate if future improvements are planned on the roadway or on adjacent <br />property. <br /> <br />10. Describe safety mitigation considered, such as signing in accordance with <br />MMUTCD, side-slope flattening, etc. <br /> <br />11. Any other pertinent factors. <br />
