Citv of Minneapolis NEAR NORTHSIDE REDEVELOPMENT - e =rJ "Treauruvu Train"approach to removing stonna•mrr corunmianmc. Artist's,sketch illustrntine the aoornach inteerated into a New Noahmde park. Sronnwnter will discharge from streets acrd storm pipes through forebays.nrr ass level spreaders,and through infiltration areas. Once cleansed,water will flow iron open ponds. A"treatment train"approach will clean runoff prior to discharge into new ponds and the Mississippi River. Treatment techniques will include grit chambers,forebays, level spreaders,infiltration strips.turf infiltration.amended soil profiles•and dry meadow,wet meadow,and aquatic plant communities. A detailed management plan with treament protocols mid frequencies is being developed. Middle Mississippi River Watershed Management Organization(MMRWMO)Year 2002 allocation of$1 million will be applied to Phase 1 area construction costs for non-point source pollution water quality treatment for more than 400 acres. Other funding sources,such as state bond funds,city capital funds and sewer fund,and Metropolitan Council grant funds,will pay for other Near Northside water system components such as storm drains,culverts,headwalls,the opening of the Bassett Creek watercourse,and amenity features. This innovative project will serve as an important model for developers and municipalities--for retrofitting natural systems and integrated stonnwater management into die urban core,and for incorporating watershed protection throughout the residential deveioliniclit planning process.

The various colored areas indicate the many subwatersheds that will be tributary to the Near Northside water system. The City of Mumeapolis'Near Northside Redevelopment project will create 900 units of mixed-income.mixed-density•high-amenity housing in north Minneapolis on the site of four demolished public housing developments. The area has long suffered from wet areas and structural problems due to clay and organic deposits in this ancient river valley. The innovative water and park system will be built in areas of the most problematic soils for housing and will manage die area's rmtoff,improve water quality,create a sense of place and neighborhood pride,and bring back a watercourse and wetlands to Bassett Creek's historic floodplain area. Demolished barracks-style housing and superblocks--with frequent stonnwater infiltration problems as in photo at left--will be replaced wide single-family and multi-family]lorries whose scale and style are drawn from die city's best traditions and most beloved neighborhood features. public housing and other low-income units will be interspersed with,and indistinguishable from,market-rate housing. ;r• r f Dti'_
