4.2.C. SR 07-10-2000 Howard R, Green Qompany GONSULTING ENGINEERS July 6, 2000 File: 808200-0060 Item ~ 4.2.C The Honorable Mayor and City Council City of Elk River 13065 Orono Parkway Elk River, MN 55330 RE: MAIN STREET STRIPING CITY OF ELK RIVER, MINNESOTA Dear Council Members: As the City prepares to proceed with the overlay of Main Street between Trunk Highway (TH) 169 and the railroad tracks to the west, the City Council should consider the potential restriping of Main Street after the overlay. Main Street is approximately 52 feet wide and is striped for two lanes of traffic and two parking lanes. Consideration should be given to restriping it after the overlay to eliminate the parking and provide more traffic lanes. The 1999 traffic count data provided by Mn/DOT indicates the average daily traffic is 7,700. This number can be anticipated to rise quickly when the commercial opportunities at Elk River Crossing open in the fall of the year. Generally speaking, a two-lane road can carry up to 10,000 cars a day. However, this capacity is reduced by the number of left turn opportunities along the roadway. With Main Street, there are four intersections and a significant number of commercial and residential driveways for left turn opportunities. Therefore, the total capacity of a two-lane Main Street would be considered somewhat less than 10,000 cars per day. I have visually observed the on-street parking uses along Main Street over the past several weeks. It has been my observation that there are consistently a few cars parked along Main Street. It is not clear to me whether this parking is due to convenience, being closer to the businesses than from their parking lots, or a matter of necessity caused by a businesses' lot being full. My guess is that the reason would be the former, the parking by convenience. If the City Council wants to consider restriping Main Street to eliminate parking and provide more lanes, there are two options available. They could restripe Main Street to a four-lane roadway with two lanes in each direction or to a three-lane design with one lane in each direction and a center left turn lane. Recent Mn/DOT studies have shown that the three-lane design contributes to a reduction in accidents, versus a straight four-lane roadway where there are significant left turn movements.

I can follow up with the City Council and provide sketches of what the road section would look like in both scenarios. I can also provide some of the Mn/DOT documentation relative to accident history on both types of roadway. Following is the question I would like to have answered on Monday evening: Is the City Council in favor of eliminating parking and restriping the roadway to carry the increasing traffic on Main Street? By the way, if the City Council decides to eliminate parking and restripe the roadway, it would be the staff's intent to send a memo to every property owner and business owner along Main Street informing them of this change. We would also include information relative to traffic during the construction process. If you have any questions regarding these issues, I will be in attendance at your July 10, 2000, City Council meeting. Sincerely, Howard R. Green Company Terry J. Maurer, P.E.
