These include: x The State Aid Office will allow for a half rural / half urban typical section. However, the office does not allow for a half reconditioning / half reconstruction typical section. This implies that any roadway which is half ‘reconstructed’, such as where curb is added for more than 20 percent of the length, must meet reconstruction standards. x There are a number of factors that the State Aid Office uses in determining the classification of various pedestrian facilities as either a ‘walk’ or a ‘trail’. The factors include material (concrete vs bituminous), width, other adjacent facilities such as bike lanes or shoulders, and resulting anticipated types of users of the facility. If bicyclists are anticipated to be used on the facility as a result of the section design, the State Aid office indicated they would consider the facility a trail. However, if the users are primarily going to be pedestrians and other features are provided for bicycle users in each direction (such as wide shoulders or bicycle lanes), the classification would likely be a walk, regardless of width or material. Without additional features provided for bicycle users, it would likely be classified as a trail. Additionally, facility widths equal to or greater than 8 feet are typically considered a trail and less than 8 feet are typically considered a walk. Variances from State Aid Rules are determined on a quarterly basis by the Variance Advisory Committee to allow for deviation from the minimum design standards. State Aid Staff would not immediately indicate support for a variance for this corridor without vetting of available alternatives and defined physical constraints which could not be overcome. The attached alternatives were developed to see whether state aid rules could in fact be met and if so, the state aid office would not be supportive of a variance. Last, State Aid representatives were clear that project costs are not a sufficient reason for a variance.
