The one exception is the I-90 <br />eastbound ramps/Railroad Street intersection, which degrades to LOS D. Although other Alternatives 1 <br />and 2 tenure options may reduce weekday trips due to seasonal residences, this scenario is considered <br />relevant to potential impacts of end-of-weekend trip generation exiting the project vicinity. <br />The cumulative effects of buildout of the proposed PUD with PUD density development of other land in <br />the vicinity results in delay increases of up to 144.2 seconds/vehicle and four intersections would operate <br />worse than the LOS C standard: <br /> I-90 eastbound ramps/Railroad Street – LOS F; <br /> I-90 westbound ramps/Railroad Street – LOS D; <br /> Sparks Road/Railroad Street – LOS F; and <br /> Spark Road/Pit Way – LOS E. <br />The I-90 eastbound ramps/Railroad Street intersection is currently stop-controlled for the eastbound off- <br />ramp only and a high eastbound left-turn volume (275 vph) is the primary contributor to high delays.
