carry trips generated by the AUAR development. Major characteristics of these roadways are summarized <br />in Table 2. <br />1-35W is a north -south Interstate Highway that runs along the western boundary of the AUAR study area. <br />Since the 2014 AUAR, there have been multiple changes to 1-35W's ramps near the site. Among the <br />changes, roundabouts were constructed at the ramps to County Road H, a roundabout was constructed <br />at the northbound 1-35W ramp to CSAH 3, and the interchange with CSAH 96 was converted to a Diverging <br />Diamond Interchange (DDI). <br />US Highway 10 is an east -west United States Highway that runs along the southwest boundary of the <br />AUAR study area. Since the previous AUAR, no major changes have taken place to the geometry of US <br />Highway 10 near the AUAR study area. <br />CSAH 96 is an east -west County roadway that runs along the southern boundary of the AUAR study area. <br />The roadway has seen no major changes since the 2014 AUAR traffic analysis besides the aforementioned <br />DDI with 1-35W. <br />CSAH 9 (County Road H) is an east -west county roadway that serves as one of two major access roadways <br />to the proposed development. As previously mentioned, two roundabouts have been constructed at the <br />1-35W ramps. The intersection of County Road H & Mounds View Boulevard was also reconstructed with <br />significant lane changes including the expansion of County Road H to a four -lane roadway from two -lanes. <br />CSAH 10 (Mounds View Boulevard) is a roadway which runs generally in a northwest/southeast direction. <br />For the purposes of this analysis, the road is considered a north -south roadway. The road ends south of <br />the County Road H intersection where it splits off to 1-35 and US Highway 10. <br />TABLE 2: SUMMARY OF EXISTING ROADWAY CONDITIONS <br />FUNCITONAL <br />NUMBER OF <br />POSTED <br />STREET NAME <br />STREET NUMBER <br />MEDIAN <br />CLASSIFICATION <br />LANES <br />SPEED <br />1-35W <br />1-35 <br />Principal <br />8-12 (2) <br />60 mph <br />Yes <br />Arterial (1) <br />"A" Minor <br />US Highway 10 <br />US 10 <br />Reliever (1) <br />4 <br />60 mph <br />Yes <br />"A" Minor <br />County Road 96 W <br />CSAH 96 <br />4 <br />50 mph <br />Yes <br />Expander(1) <br />"A" Minor <br />County Road H <br />CSAH 9 <br />Expander(1) <br />4 <br />40 mph <br />Yes <br />Mounds View <br />"A" Minor <br />Boulevard <br />CSAH 10 <br />Reliever (1) <br />4 <br />50 mph <br />Yes <br />(1) City of Arden Hills — 2040 Comprehensive Plan <br />(2) 1-35W has twelve lanes north of the US 10 interchange and eight lanes south of the interchange. <br />3.2 STUDY AREA <br />Based on discussion with City staff, the updated traffic analysis will focus on key intersections and omit <br />fringe intersections that were originally studied as part of the 2014 AUAR Traffic Study. This is because <br />many of the proposed mitigations from the 2014 AUAR have been implemented. The existing roadway <br />network geometry and intersection control is shown in Exhibit 2. Based on the changes to geometry and <br />the anticipated effects of the site generated traffic on the roadway network, it was determined that the <br />following intersections would be included in this traffic study: <br />TCAAP AUAR Update I Traffic Analysis <br />April 2024 <br />
