Traffic Commission 6801 Delmar Boulevard, University City, Missouri 63130, Phone: (314) 862-6767, Fax: (314) 863-9146 5. Drivable Mock Roundabout on Delmar Blvd. and Trinity Avenue – Update Commissioner Wofsey presented this item: Sinan Alpaslan explained the real life measurement of the functionality of the traffic with the proposed roundabout as implemented on the street. Traffic models currently show that traffic levels of service at the intersection of Delmar Blvd. and Trinity Ave. will be at acceptable levels. However, a real life trial of the proposed design has been requested. In response to that request, the City is planning to temporarily install a drivable mock roundabout at the referenced intersection and watch it for 30 days to see how the flow is affected and how pedestrian and vehicular movements around it are affected. St. Louis County Highways and Traffic has jurisdiction on Delmar Blvd from the Lion monuments to the west. The City will comply with their requirements. Commissioner Hales proposed the question, has the county specified how they are going to quantify what their concerns are for the safety and congestion and how are they going to measure it. Major concern will be if traffic starts backing up to Big Bend or some drastic result they will ask for it to be removed immediately. Commissioner Wofsey asked how St. Louis County would be distinguishing between changes in traffic flow from west of the Lions that are precipitated by the roundabout from those that are precipitated by the narrowing of the lanes to the west. They will compare the existing data to when the mock is in place. The roundabout is narrowing lanes slightly but more importantly eliminating one lane. Ms. Peggy Mooney addressed the Commission and attended the meeting on behalf of University Heights #1 Subdivision which is North of Delmar and the entrance/exit at Trinity and Yale. Per Ms. Mooney, the roundabout at Trinity is going to encroach upon the property of that subdivision which butts up to Delmar. The residents and trustees of the subdivision are very concerned about the encroachment on their property and the effect it will have on their residents. When is the mock roundabout proposed to happen? Councilmember Carr said that the Council received the numbers for the cost of the mock roundabout. In the near future, a vote will take place as to whether or not Council will be funding it. This will be done in the next couple of months. Councilmember Carr also added that University Heights #1 Subdivision will be included in on the conversation in terms of the roundabout itself. Ms. Elise Glickert addressed the Commission and expressed her concern about the lack of hearing assistance at the meeting. She stated that Delmar is travelled by everyone in University City. It is her understanding that everything they remove to accommodate the roundabout will be restored. However, the islands that have been there for over 100 years are not to be restored. She is opposed to the idea and concerned about the integrity of the City’s historic district. Commission Wofsey asked staff to look into the hearing assistance issue.
