12 <br /> <br />Traffic Capacity <br /> <br />A ratio of volume to capacity is used to analyze traffic congestion. A road with a volume to <br />capacity ratio of 1.0 means the traffic volume is nearly equal to the traffic capacity and will feel <br />congested to motorists. Per the traffic study, three (3) sections of roadways (20th Ave north of <br />Birch St, 20th Ave south of Birch St and Birch St) were analyzed under Existing, 2024 No- <br />Build and 2024 Build scenarios. No volume to capacity ratio exceeded 0.45. None of study <br />roadways are expected to exceed their daily capacities. <br /> <br />Level of Service <br /> <br />Level of Service (LOS) is used to describe the operating conditions of an intersection. Facilities <br />are given letter designations from “A” (best operating conditions) to “F” (worst conditions). <br /> <br />Section 1001.013(2)(c), Premature Subdivision of the City’s Subdivision Ordinance establishes <br />minimum Level Of Service (LOS) requirements. The ordinance states that if the LOS is A or <br />B, the proposed subdivision shall not the degrade the LOS more than one grade. If the LOS is <br />C or D, it shall not degrade the LOS. Intersections with a LOS of E or F must be improved to <br />ensure a LOS of D or better. <br /> <br /> Existing Peak Hour LOS Proposed Peak Hour LOS <br />Intersection A.M. Peak P.M. Peak A.M.

They have identified <br />the need for right and left turn lanes on CSAH 54 (20th Avenue). These details shall be <br />provided by the developer. <br /> <br />CSAH 34 (Birch Street) Corridor Study <br /> <br />In April 2011, Anoka County and the City of Lino Lakes hired SRF Consulting Group to <br />develop a corridor study along CSAH 34 (Birch Street). Per the recommended corridor plan, <br />future full-access intersections near Nadeau Acres are every ¼ mile. No access (full or partial) <br />is proposed onto CSAH 34 (Birch Street) from Nadeau Acres. A pedestrian (trail or sidewalk) <br />corridor will connect Nadeau Acres to Birch Street. <br /> <br />I-35E/CR J/Centerville Road <br /> <br />Staff is aware of current traffic concerns at I-35E/CR J/Centerville Road but these are outside <br />the scope of Nadeau Acres. These interchanges are currently under evaluation by other <br />government agencies. Ramsey County is working on a federal transportation funding <br />application to reconstruct bridge and ramp terminals and CR J/Centerville Road intersection.
