New Lake Elmo Elementary School & Oak-Land Middle School August 1, 2024 Transportation Study Page 4 Table 1. Existing Roadway Characteristics (1) Functional Classification based on the City of Lake Elmo’s 2040 Comprehensive Plan. (2) Functional classification transitions from an A-Minor Reliever to a Minor Collector east of Manning Avenue. (3) Functional classification transitions from a Major Collector to an ‘Other Arterial’ north of 10th Street. (4) Keats Avenue transitions from 4-lane divided A Minor Expander with a speed limit of 55-mph to a 2-lane divided local street with a speed limit of 35-mph north of 10th Street. (5) Speed limit change occurs north of Hudson Boulevard, with a posted speed limit of 55-mph to the north, and 50-mph to the south. From a traffic control perspective, the Manning Avenue/10th Street and Manning Avenue/Oak-Land Middle School south access intersections are signalized, and the 10th Street/Keats Avenue and 10th Street/Lake Elmo Avenue intersections are unsignalized with all-way stop control. All other study intersections are unsignalized with side-street stop control. Existing geometrics, traffic controls, and traffic volumes in the study area are shown in Figure 2. Pedestrian and Bicycle Facilities A field assessment was completed to identify the current local and regional pedestrian/bicycle facilities within the study area and is illustrated in Figure 3. While Keats Avenue (CSAH 19) has an off-street trail that provides connectivity from Woodbury to the Lake Elmo Park Reserve, the rest of the study roadways generally lack off-street pedestrian/bicycle facilities. It should be noted that the high speeds (i.e. 55-mph) along these roadways likely deter most pedestrians and bicyclists from using the shoulder. In general, the nearby local neighborhood developments include internal pedestrian/bicycle facility networks. Given the close proximity of these residential neighborhoods to the two school sites, it is important to consider pedestrian/bicycle connectivity within the project area. Further discussion regarding pedestrian/bicycle considerations is provided later in this document. Safety Analysis A safety analysis was completed to understand any crash trends or geometric issues at the study intersections. The safety analysis was based on reported crashes using MnDOT’s Crash Mapping Analysis Tool (MnCMAT2) from April 1, 2019, to March 31, 2024, which represents the most recent five-year period available. Results of the safety analysis are summarized below and shown in Figure 4, while detailed crash type/rate information is included in the Appendix.
