Mr. Lonnes replied that there would be a lane drop prior to entering the roundabout, which would <br />be pretty straightforward. He stated that if the lane is not dropped, there would be one lane that <br />exited onto the highway with the other lane continuing straight. <br /> <br />Mayor LeTourneau commented that his concern would be that the lane drop would create a pinch <br />point at the bridge which would cause a backup. <br /> <br />Mr. Lonnes replied that currently there is not a volume that justifies the multilane roundabout, as <br />a multilane roundabout can cause additional confusion. <br /> <br />Mr. MacPherson noted that will be part of the analysis that will still need to be completed. He <br />stated that the nice thing about the roundabout option is that the turn lanes do not need to be <br />included in the bridge, as that additional width increases cost. He stated that provisions can be <br />added in the case that an additional roundabout lane needs to be added in the future. He stated that <br />if the traffic volumes for the next ten to 15 years do not warrant an additional lane, they would <br />recommend the one lane roundabout option at this time. <br /> <br />Councilmember Riley referenced Sunfish Lake Boulevard and the tight diamond option and asked <br />for additional information on why that option was dismissed. <br /> <br />Mr. Lonnes stated that the tight diamond was not dismissed in entirety. He explained that space <br />wise it would be tight and operationally would cause stacking. He noted that off ramp would also <br />be expensive to build. He stated that half of the tight diamond is still in the mix, but it will be a <br />variation. <br /> <br />Deputy City Administrator Gladhill noted that the southern half of the leg is a City road while the <br />northern half is County. <br /> <br />Mayor LeTourneau asked if the ramp could be extended to make the slope less impactful in terms <br />of stacking. <br /> <br />Mr. Lonnes replied that could be done but they do not want that level of stacking and would like <br />to avoid that. <br /> <br />Councilmember Menth asked for input on the traffic control at the intersection. <br /> <br />Mr. Lonnes replied that currently it is shown as a stop sign but noted that additional tests would <br />be run. <br /> <br />Mr. MacPherson replied that the north/south road would be a through movement uncontrolled and <br />the ramp would be the side street stop. <br /> <br />Deputy City Administrator Gladhill asked if a traffic signal would assist in improving the <br />intersection grade of E. <br /> <br />Mr. Lonnes replied that a traffic signal would not be warranted. <br />City Council Work Session / October 27, 2020 <br />Page 3 of 7 <br /> <br />
