<br /> <br />Feasibility Report Page 5 <br />Snelling Avenue North and County Road E - Street and Utility Improvements <br />City Project Number PW 20-0100 DRAFT <br />A 140- foot long segment of Snelling Avenue North located approximately 400 feet north of <br />Highway 51 was reconstructed in 2018 during replacement of the bridge that conveys <br />drainage from Lake Josephine to Lake Johanna. <br />Snelling Avenue North serves as a collector roadway and is currently designated as a <br />Municipal State Aid street (MSAS 111). Average daily traffic data indicates a volume of <br />1600 vehicles per day in 2017, the most recent data available from MnDOT. The roadway <br />is posted at 40 miles per hour in both the northbound and southbound directions. <br />Cummings Lane is a rural section residential street extending approximately 575 feet east <br />from Snelling Avenue North and lies within a 60 foot wide right-of-way. The existing <br />bituminous pavement rating is below 20, with significant block cracking and segments <br />having complete pavement failure. Pavement thickness was found to be only 2 to 3 inches <br />in various locations. Routine patching and pavement resurfacing are no longer cost effective <br />due to the extent of pavement deterioration. The storm sewer catch basin located at the east <br />end of the street collects surface drainage and discharges into the right -of-way for Trunk <br />Highway 51. This catch basin structure and corrugated metal outlet pipe are deteriorated <br />based on inspections conducted in 2020. <br />Bussard Court is an urban section residential street serving 15 residential properties to the <br />west of Snelling Avenue North. This street is approaching the end of service life and should <br />be considered for reconstruction within the next five years. However, the first 100-feet <br />directly west of Snelling Avenue is highly deteriorated due to unstable subgrade conditions. <br />The Public Works department has made several attempts to complete small repairs, but the <br />pavement continues to fail and has become difficult to maintain in the winter and spring. <br />Subgrade corrections are needed to stabilize the pavement. <br /> <br />Area 2 – Intersection of Snelling Avenue North and County Road E <br />The intersection of Snelling Avenue North and County Road E is currently controlled by an <br />all-way stop condition. The east leg of the intersection consists of one eastbound and <br />westbound travel lane with a continuous left turn lane and an average daily traffic (ADT) <br />volume of 10,000 vehicles per day (2017). The north leg of the intersection consists of one <br />northbound and southbound travel lane with a dedicated southbound left turn lane and an <br />average daily traffic volume of 6,600 vehicles per day (2019). The west leg of the <br />intersection consists of one eastbound and westbound travel lane with an eastbound left turn <br />lane and an average daily traffic volume of 5,100 vehicles per day (2019). The south leg is <br />described above. <br /> <br />The intersection is contained within a large swath of right of way stemming from the previous <br />1950’s intersection configuration as a state highway. The intersection has been in its current <br />configuration since 1974. Minor improvements were completed along the north and east <br />legs of the intersection in 2018 during construction of an adjacent pedestrian trail. <br /> <br />Pavement conditions at the intersection are showing signs of distress, with generally lower <br />pavement condition ratings for the south leg of the intersection as described above. <br />Intersection functionality and crash history are described below.
