TABLE 14: MAXIMUM DENSITY SCENARIO (2040) BUILD DELAY AND LOS SUMMARY <br />INTERSECTION <br />TRAFFIC CONTROL <br />AM PEAK HOUR 1W <br />PM PEAK HOUR <br />DELAY <br />(Sec/Veh) <br />LOS <br />DELAY <br />(Sec/veh) <br />LOS <br />Mounds View Boulevard & County Road H <br />Signal <br />41.2 <br />D <br />67.3 <br />E <br />CSAH 96 & US Highway 10 SB Ramp <br />Signal <br />35.2 <br />D <br />21.7 <br />C <br />CSAH 96 & Northern Heights <br />Signal <br />27.7 <br />C <br />23.2 <br />C <br />County Road H & 1-35W SB Ramp <br />Roundabout <br />6.1 <br />A <br />5.9 <br />A <br />County Road H & 1-35W NB Ramp <br />Roundabout <br />4.8 <br />A <br />14.8 <br />B <br />Note 1: Overall intersection delay and LOS reported for signal control. For side -street stop control, delay and LOS are reported for the worst <br />movement followed by the overall intersection delay and LOS. <br />Similar to the zoning density scenario, NB, EB, and WB left turning movements at Mounds View Boulevard <br />& County Road H are anticipated to have 95th percentile queues that are approaching their storage <br />capacity or have through movement queues that extend beyond the turn lanes which prevents vehicles <br />from getting into the turn lane until through queues dissipate. It is not anticipated that queuing at the <br />intersection would impact adject intersections. <br />At the CSAH 96 & US Highway 10 SB Ramps, the southbound left is anticipated to see 951h percentile <br />queues exceed their storage length, but the queues are not anticipated to impact traffic along the <br />freeway. The westbound left turn lane is nearing its capacity during the AM peak hour. <br />At the south TCAAP access (CSAH 96 & Northern Heights), queueing of the added southbound approach <br />is anticipated to be sufficient with the proposed layout if the southbound through lane is striped as a <br />shared through/right turn lane. The southbound left turn storage lanes may need to be extended to 400' <br />in length, to accommodate anticipated queues. <br />5.7 MAXIMUM DENSITY SCENARIO WITH DISCOUNT RETAIL (2040) LEVEL OF <br />SERVICE ANALYSIS <br />A capacity analysis was performed for Maximum Density Scenario Build (2040) traffic conditions at the <br />study intersections to determine the traffic impacts of the highest intensity scenario of the proposed <br />alternatives. The roadways were modeled with future baseline geometry and signal, as shown in Exhibit <br />4. The analysis was performed for weekday AM and PM peak hours and is based on the traffic volumes <br />provided in Exhibit 12. These volumes were calculated by adding together the following: <br />• Design Year (2040) No -Build Traffic Volumes (Exhibit 5) <br />• Maximum Density Scenario Total Site Trips (Exhibit 9) <br />Table 15 provides a summary of the capacity analysis at the study intersections. Based on the analysis, <br />the roadway network is anticipated to see a significant decline in operations compared to the 2040 No - <br />Build scenario, with some intersections being at or near capacity. The intersection of Mounds View <br />Boulevard & County Road H is anticipated to operate at LOS E during the PM peak hour with over 70 <br />TCAAP AUAR Update I Traffic Analysis <br />April 2024 <br />
