• • Memo to Jim Studenski Page 3 June 4, 2002 Review of Access Options for Behm's Century Farm, 6th and 7th Additions Project • Providing for a more balanced distribution of the projected 1630 daily vehicle trips to be generated by the planned 170 new homes over Sunset and Fourth Avenues, rather than solely impacting Sunset Avenue under Options 3, 4, and 5. • Providing access to the west for 16 existing Carl Street homes, including more convenient access to the I -35W interchange at Lexington Avenue. 2) "The design of minor collectors should discourage excessive speeds." Narrower streets with a meandering alignment are best for discouraging vehicle speeds in excess of designated limits. Option 1 provides a straight alignment and would be the least effective in meeting this principle. The other options have similar degrees of curvature in their designs and would all be more effective in discouraging excessive speeds than Option 1. For all access options, a previously discussed pavement width of 44 feet could encourage excessive speeds through the planned residential neighborhood. The 36 -foot pavement width recommended in Appendix B of the Transportation Plan for minor collectors in low density residential districts would be more effective in meeting this planning principle. 3) "Minor collectors should permit the efficient use of land for laying out plats." Based on the previous analysis of access options conducted by Metro Land Surveying and Engineering for Century Farm Development, Inc., Option 4 would accommodate 38 new residential parcels, compared to 36 new parcels for Option 2, and 29 new parcels under Option 3. Option 4 would be slightly better than Option 2 with regard to meeting this planning principle. 4) "Minor collectors should be designed to minimize through traffic. The layout of minor collectors should not promote diversion of traffic from arterials and major collectors." Options 1, 2, and 4 provide a relatively horizontal east -west alignment that would not create a time advantage for those traveling on the surrounding arterial and collector streets (i.e., Main Street, Sunset Avenue, Fourth Avenue, and Lilac Street). Option 3 provides a diagonal alignment from southwest to northeast and could arguably promote cut - through trips for travel in either of these directions with diversions from Sunset Road and Main Street. Similarly, Option 5 could promote diversions from Main Street and 4th Avenue for trips moving southeast or northwest.
