<br />Elk River Planning Commission <br />October 23, 1998 <br />Page 3 <br /> <br />Additional right-of-way will likely be needed from the plat to accomplish <br />these proposed roadway improvements <br /> <br />c) <br /> <br />The site plan shows a right-inlright-out along CSAH 12, between the main <br />entrance and the intersection of Tyler Street and CSAH 12, at the east <br />edge of the development. The Traffic Impact Analysis report indicates <br />that this access point will operate at a level of service B. It does not <br />indicate whether a right turn lane and/or short acceleration lane will be <br />needed for its efficient operation. It should be pointed out that this access <br />point does not meet Sherburne County's adopted guidelines for access <br />onto County State Aid Highways. This access is also of concern to City <br />staff. <br /> <br />d) <br /> <br />CSAH 12/Tyler Street <br /> <br />. <br /> <br />This is the main intersection with the City's new north-south transportation <br />corridor along the east side of this development. The design of this <br />intersection meets or exceeds the recommendation contained within the <br />Traffic Impact Analysis. The Traffic Impact Analysis indicates that a <br />signal control will need to be installed once Elk Park Crossing begins to <br />near full development. We have anticipated this in the design of Tyler <br />Street and CSAH 12, and conduits are being placed for the future <br />signalization of this intersection. <br /> <br />e) <br /> <br />Tyler Street/South Development Access <br /> <br />The design of Tyler Street at this location meets or exceeds the Traffic <br />Impact Analysis recommendation for lane configuration. Specifically, <br />there will be a dedicated left turn lane into the site, which exceeds the <br />Traffic Impact Analysis recommendation. One thing that Elk River <br />Crossing should consider is future residential development east of this <br />location. We would anticipate that there would be a four-legged <br />intersection at some point in the future. <br /> <br />f) Service Entrance/Tyler Street <br /> <br />The Traffic Impact Analysis is silent on this intersection, but the site plan <br />does show a full access to the rear of the large commercial sites off of <br />Tyler Street. Staff would recommend that a right-in/right-out be allowed <br />at this point for service vehicles, but that the median remain intact to <br />preclude left turns at this point. <br /> <br />. <br /> <br />Howard R.
