ARDEN HILLS CITY COUNCIL WORK SESSION — DECEMBER 20, 2021 2 Councilmember Scott asked if all three solutions would impact moving Lindey's entrance. Mr. Corkle responded that the all -way stop wouldn't change it, but a signal or roundabout would. He also noted that it doesn't take much increase in volume to cause issues at an all -way. The roundabout is able to handle the adjustments. Councilmember Holden felt a traffic signal would be safer for pedestrians than a roundabout. Mr. Corkle said a nice thing about a roundabout is that you are only looking one direction to cross, you get to the median and look the other direction to cross; you only cross half the roadway at a time and traffic is moving in only one direction. Councilmember Holmes asked what the City Engineer thought was the best option. Public Works Director/City Engineer Swearingen replied that the warrants are met for a signal or roundabout, and so it becomes engineer preference. He likes roundabouts and sees the benefits of having one, but public participation and education is necessary. Ramsey County will have an online survey and open house. They are not far enough into the design process to discuss cost. When designing a roundabout they will need to look at what materials will be used, which will affect cost. The city will pay 1/4 and the county will pay 1/4. Mr. Corkle added that it is a single lane roundabout and they are trying to size it appropriately for the intersection. Mayor Grant noted that Xcel Energy has a large switch station and there were also other utilities in the area. Councilmember Holden felt when people go through roundabout they go fast and continue to accelerate once they leave the roundabout. Mr. Corkle said typically you are yielding for other cars in the roundabout. Speeds within roundabouts are generally 15-18 mph. Ms. Lundquist noted that the type of accident in a roundabout is different from accidents at a signal light. Generally, accidents are fender benders and much less severe in a roundabout. Ms. Lundquist said next steps would be a survey on the County website, and an open house will be scheduled for January. There would be social media blasts, and postcards sent within a half mile, along with flyers for the schools to post. Public Works Director/City Engineer Swearingen stated that Ramsey County did a postcard mailing for the Lake Johanna Boulevard project open house and he reviewed the list, which should be similar to this project. Councilmember Scott said according to the study, overall projected costs would favor the roundabout due to traffic signal maintenance. He wondered how it leveled out and favored the roundabout.
