A brief summary <br />of these three documents is provided below. <br />Preliminary Scoping Document, Old Snelling Avenue Improvements (2010) <br />The City completed a preliminary scoping document for proposed improvements to Old <br />Snelling Avenue North from County Road E to TH 51 in December 2010. This study <br />reviewed five project alternatives as described below. <br /> Alternative 1: Urban Reconstruction (with parking on both sides): Full road <br />reconstruction with one 12 foot driving lane in each direction, eight foot paved shoulders <br />for parking, and concrete curb and gutter. <br /> Alternative 2: Urban Reconstruction (with no parking): Full road reconstruction with <br />one 12 foot driving lane in each direction, a two foot curb reaction distance, and concrete <br />curb and gutter. <br /> Alternative 3: Rural Reconstruction: Full road reconstruction with one 12 foot driving <br />lane in each direction and 6 foot paved shoulders (no additional curb and gutter). <br /> Alternative 4: Rural Reconditioning (bituminous reclaim): This alternative consists of <br />reclaiming the existing 24 foot wide bituminous roadway and reclaiming the 8 foot wide <br />shoulders. The new street and shoulder widths would be replaced to match the existing <br />section (no significant subgrade correction). <br /> Alternative 5: Bituminous Reclaim (Non-State Aid standard): This alternative consists <br />of removing Old Snelling Avenue from the State Aid system and performing an <br />improvement to the roadway segment that does not meet State Aid standards, such as <br />removing the existing paved shoulders. <br />
