This addition of the development is being served by 8- inch diameter poly-vinyl chloride (PVC) pipe along with 4-inch diameter Schedule 40 PVC service pipe to each lot. •Transportation The proposed roadways are consistent with the preliminary plat. The work in this addition includes constructing Rainy Lane, Victoria Circle, Norway Lane (from 5th Addition limits to Rainy Lane), and Osakis Street. Rainy Lane is proposed to be 36’ wide from back-of-curb to back-of-curb (this will need to be increased to 38’ wide back-of-curb to back-of-curb), Norway Lane and Osakis Street are proposed to be 32’ wide from back-of-curb to back-of- curb, and Victoria Circle is proposed to be 30’ wide from back-of-curb to back-of-curb. The applicant is proposing to add a designated right turn lane to Rainy Lane from northbound 20th Avenue (CSAH 54). The applicant is also proposing to add a designated right turn lane to Rehbein Street for southbound traffic on 20th Avenue (CSAH 54). The applicant will coordinate with Anoka County as to whether left turn lanes are warranted from 20th Avenue (CSAH 54) onto either Rainy Lane and/or Rehbein Street.
