24-30671 ASH STREET TRAFFIC IMPACT STUDY - LINO LAKES, MN <br />• 0.5% along CSAH 21/Centerville Road south of Intersection 1, <br />• 1.0% along CSAH 21/Centerville Road between Intersections 1 and 2, <br />• 1.0% for CSAH J/Ash Street east of Intersection 1, <br />• 0.8% for CSAH 21/Centerville Road north of Intersection 2, and <br />• 0% for CSAH 32/Ash Stret west of Intersection 2. <br />In the design year, 2045, with construction of the proposed development, all movements are expected to operate at a level of <br />service C or better for the Weekday AM and Weekday PM peak hours. <br />From the completed study, it is found that the proposed mixed used and residential developments along Ash Street will increase <br />vehicular volumes and average delays at the studied intersections, and the planned roadway geometry is able to accommodate <br />the changes in traffic volumes and distribution patterns. Vehicle queue lengths will generally increase but are not expected to <br />impact development site circulation. <br />Conclusions + Recommendations <br />The proposed residential and mixed -use developments along Ash Street are slated to begin operations by 2025, with full <br />completion expected by 2045. Currently, traffic conditions on the southbound approach of the CSAH 21/Centerville Rd and CSAH <br />J/Ash Street intersection are poor, operating at a level of service F. However, planned improvements, including the conversion to <br />roundabouts, are anticipated to enhance traffic flow to a level of service C or better regardless of proposed development <br />construction. While no new right- or left -turn lanes are warranted due to the developments, a left -turn lane at the CSAH 32/Ash <br />Street and Holly Drive intersection is indicated, although safety data shows no significant need for its construction. Additionally, <br />higher -than -average crash rates along CSAH 32/Ash Street suggest a need for roadway geometry changes between Monarch Way <br />and CSAH 21/Centerville Rd. A proposed realignment should meet AASHTO standards and a suggested design speed of 45 MPH. <br />Recommended for the proposed developments, sidewalks and shared -use paths should be incorporated within the developments <br />to enhance pedestrian and bicyclist connectivity. Finally, while the planned intersection geometry and traffic control should <br />accommodate anticipated traffic demands, re-evaluation is recommended if growth projections change. <br />0 Architecture + Engineering + Environmental + Planning Page 2 of 2 <br />
