It is also recommended that a utility easement be provided to encompass the proposed sanitary sewer conveyance and treatment system. Traffic and Roadways Issues relating to traffic have been discussed and addressed significantly throughout the review process for this proposed development. Mitigation of traffic issues and requirements as expressed in previous memorandums, including requirements of Anoka County and the City of Lino Lakes, remain applicable. This includes the requirement to provide mitigative traffic control measures on Sunday mornings at the intersections of Main Street with 20th Avenue North (County Road 21) and the freeway ramps, and at the church entrance on 20th Avenue North. Roadway improvements to 20th Avenue North have also been proposed in consultation with Anoka County, and the plans shall be subject to approval by the County.
