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

The project is also under review by Anoka County Highway Department. They have identified the need for right and left turn lanes on CSAH 54 (20th Avenue). Per the July 8, 2020 ACHD letter, the County will allow a shortened southbound right turn lane due to existing constraints. The turn lanes were approved by the County on July 30, 2020. CSAH 34 (Birch Street) Corridor Study In April 2011, Anoka County and the City of Lino Lakes hired SRF Consulting Group to develop a corridor study along CSAH 34 (Birch Street). Per the recommended corridor plan, future full-access intersections near Nadeau Acres are every ¼ mile. No access (full or partial) is proposed onto CSAH 34 (Birch Street) from Nadeau Acres. A pedestrian (trail or sidewalk) corridor will connect Nadeau Acres to Birch Street. I-35E/CR J/Centerville Road Staff is aware of current traffic concerns at I-35E/CR J/Centerville Road, but these are outside the scope of Nadeau Acres. These interchanges are currently under evaluation by other government agencies. Ramsey County is working on a federal transportation funding application to reconstruct bridge and ramp terminals and CR J/Centerville Road intersection. Local and County staffs are also working with state representatives on possible preliminary
