ARDEN HILLS CITY COUNCIL WORK SESSION — MARCH 21, 2022 5 Councilmember Holden reported a roundabout cost $1.2 to $1.4 million while a signalized intersection cost $300,000 to $400,000. She asked what share of this project the City would be responsible for. Mr. Johnson anticipated the City would be responsible for one leg or 25% of the project. Councilmember Holden questioned what other expenses would be included in this project. Public Works Director/City Engineer Swearingen explained the City would be completing sanitary sewer and watermain improvements and these costs were included within the CIP. Councilmember Holden inquired how Ramsey County advertised the open house. SRF Senior Project Manager Stephanie Falkers discussed the social media posts and postcards that were sent to the surrounding area. Councilmember Holden asked if Councilmember Holmes received a postcard from the County, noting she did not. Councilmember Holmes stated she received a postcard from the County. Councilmember Radziej discussed how it would take 41 years to break even between the cost for a traffic signal and a roundabout. Ramsey County Project Manager Joey Lundquist spoke to the benefits of having a roundabout in place versus a traffic signal which included lower emissions and time delays for users. Mr. Johnson commented further on the difference between the upfront costs and overall costs for a project. Mayor Grant stated the transportation issues at this intersection have to be addressed and noted the roundabout was the most efficient manner in which to address these concerns. Councilmember Holden reported the County park near this intersection was heavily utilized. She expressed concern with the fact this project did not include budget from Ramsey County to provide a trail to this park or to slow traffic down in order to allow easier pedestrian access to this park. She feared that it would be more difficult for pedestrians to get to the park with a roundabout than if a traffic signal were installed. Mr. Johnson indicated this was a difficult question to respond to. He explained an all way stop has traffic increasing their speed quickly after stopping, where roundabouts have a more calming effect on traffic. Councilmember Scott stated he believed the roundabout was the best alternative at this intersection. Councilmember Holmes commented she did not support any change at this intersection. She noted she spoke with the City Engineer and was made aware that MSA funds would be used for this project, which would help with the impact this project would have on the City's budget. She
