<br />Quiet Zone Evaluation 17 <br />New Brighton, Minnesota <br />Table 1 – Quiet Zone Area 1 Potential Improvements Effectiveness <br />Quiet Zone Area 1 QZRI RIWH NSRT <br />Improvement Concept 1 <br />(Knollwood Channelization) 1,008.98 <br />2,419.62 14,723.00 Improvement Concept 1 <br />(No Knollwood Channelization) 1,270.69 <br /> <br />As shown the calculated QZRI is lower than both the RIWH and the NSRT under <br />each concept. If implemented, either concept would sufficiently reduce the risk and <br />allow the creation of a Quiet Zone for these crossings, though improvement concept <br />2 would require additional diagnostic team review. <br /> <br />To improve safety for pedestrians, channelizing fencing should be added to force <br />pedestrians to look both ways for trains. This is less expensive than automatic gates, <br />but still provides a measure of safety for pedestrians. <br /> <br />The following work would be necessary for this zone: <br /> Additional gates for Stinson Boulevard and Shamrock Lane. <br /> Relocation of the eastern gate on Stinson Boulevard. <br /> Channelization devices to separate traffic on each approach (6 to 8 <br />approaches depending if Knollwood delineation is used). <br /> Potential new parking lot connection to Stinson Boulevard. <br /> Full upgrade to crossing gates and flashers at Silver Lake Road. <br /> Sidewalk/trail channelization. <br /> <br />Including contingency costs for additional signing, pavement markings, engineering, <br />and other miscellaneous items, the total concept cost ranges from $504,250 to <br />$524,250 depending upon the need for channelization at the Knollwood Drive <br />crossing. <br /> <br />
