Regular City Council Meeting Monday, February 23, 2015 Page 14 Right-turn only as mitigation versus r/l Mr. Vaughn opined that his interpretation of that question was whether the study recommended restricted turn movements, which had not been reviewed as part of this study, and further opined that option would not be appropriate given the inter- sections being dealt with. If the suggestion was to not allow left turns to happen from Twin Lakes Parkway at Fairview Avenue or Terrace Drive in an effort to improve traffic, Mr. Vaughn opined that it would not be appropriate, but a use such as at a WalMart access point was a better use for that option, at a develop- ment's access point. Mr. Lux advised that he had interpreted the question yet differently, targeting only certain movements at some locations, which he thought about at Lydia Avenue and different southbound turn movements or adding lanes to target improvements without a large land impact. Mr. Lux suggested this may be a future strategy to consider. How is existing data used in regional trips and larger trips specific to this area Mr. Vaughn advised that there were few regional trips expected to use Twin Lakes Parkway, and cautioned that the system as it is today could not be com- pared to 2030 scenarios, improvements coming in, and with additional lanes add- ed. With the sub-regional or regional movements on major arteries (e.g. Highway 36, I-35W and I-694), Mr. Vaughn opined that without those regional system im- provements, then it may be possible to see future regional trips using the Park- way. Certain number of lanes east of Snelling and how that impacts analysis of this study or if it did Mr. Culver advised that significant back-ups are seen both east and west of Snel- ling Avenue, often associated with event-related times; or during snow or other incidents on the regional system. However, Mr. Culver opined that he had not observed any back-ups to or past on the east side of Snelling Avenue backing up Snelling Avenue itself, which from his perspective would be the only situation impacting demand on the west side of Snelling. Mr. Culver opined that it could be debated why the four lane County Road C had been reduced to two drive lanes with turn lanes, it did provide safety benefits in that design with a median divided roadway along with aesthetic values and traffic calming efforts versus the nar- rower medians with more turn lanes and/or drive lanes. Mr. Culver suggested there may be an opportunity to review that design in the future if significant ca- pacity issues develop on the east side. However, Mr. Culver opined that he had not observed any issues on the east side that impacted operations through the Snelling Avenue intersection, even though sometimes the back-ups are long into Hamline Avenue,but not impacting the west side of Snelling Avenue. Mr. Culver suggested traffic signal timing for more green time may help alleviate the issue.
