A2013-9b Staff Report July 9, 2013 Page 5 of 9 the preliminary discussion between the City and Anoka County Highway Department staff. The street east of the library will not be constructed as part of the Ruin River Shores Development. The County is completing a road reconstruction project on County Road 116 that will result in a few changes in the area. 6th Avenue/County Road 116 intersection will become a right -in, right -out intersection. 6t" Avenue south of County Road 116 will be closed. A traffic study completed by WSB analyzed the land use as it relates to the projected traffic volumes for the area. Taking into account the future land use for the area including single family and townhomes west of the library and a large commercial development to the east, the traffic volumes for the loop road west of the library had a projected volume of approximately 6,000 vehicles per day. The change in the roadway design and the land use from townhomes to single family will reduce the projected traffic volumes on the road. The intersection northeast of the library is proposed to be reconfigured to encourage drivers to take 6th Avenue when going west bound from the commercial area along 7th Avenue. The intersection of 431'd Avenue and 7th Avenue (County Road 7) in the commercial area is anticipated to be signalized in the future. Those drivers wanting to go eastbound on County Road 116 will likely use this intersection on 7th Avenue to exit the commercial development and the existing signalized intersection of 7th Avenue and County Road 116. Grading/Drainage/Storm Water Management The Lower Rum River Watershed Management Organization has reviewed the proposed grading, storm water, and drainage plans for the site. The plans show water quantity and quality management is to be provided within two ponds and five rain gardens. The following is an outline of the ownership for the stormwater ponds and rain gardens. • All rain gardens shall be owned and maintained by the Homeowners Association. The rain garden will need to be construction and installed according to current MPCA requirements. • The City is reviewing whether or not we will have to utilize the pond located within Lot 32, Block 2 for our storm water needs for the south loop road south of County Road 116 to the High School. In the event the City will need to utilize this pond, the ponds will be maintained by the City. If the City does not need to use it, the ponds shall be maintained by the Homeowners Association. In either scenario, the retaining wall around the pond shall be maintained by the Homeowners Association. Separate agreements would be drafted for easements, etc. if we do share in the maintenance responsibility. Parks, Trails and Vegetation Generally, any subdivision within the City of Anoka is required to pay park dedication fees per unit created. The Anoka Park Board recommends the City Council accept the cash in lieu of land for the park dedication. The fee as adopted in the Anoka Master Fee Schedule is $2,543 per unit.
