Restoration of the entire two mile Upper 40 tributary of the Chagrin River is currently underway in the eastern suburbs of Cleveland, Ohio. The project represents a unique collaborative partnership between the Villages of Mayfield, Gates Mills, and Cleveland Metroparks and illustrates all of the funding, design, and construction issues common to urban and suburban stream restoration.

Increased runoff from suburban development over the last 50 years had created severe flooding and erosion problems, causing a source of conflict between watershed partners for 20 years. Once the partners reached a consensus on cooperation, they commissioned a restoration masterplan for the tributary. An interdisciplinary consultant team of landscape architects, engineers, ecologists, and permitting specialists diagnosed watershed problems, identified restoration locations, and developed feasible watershed solutions. More critical however, was developing an implementation plan consisting of estimated project costs, funding sources, and a funding plan. The stream restoration masterplan featured natural channel design techniques and restoration of floodplain functions. The project will dramatically increase stormwater storage capacity, restored floodplain functions to 2000 lineal feet of stream, daylight over 2000 lineal feet of formerly culverted stream, construct 2-3 acres of wetlands, and enhance a 40 acre wetland complex.

Phase One of a four phase restoration master plan was constructed in 2004, phases two and three are currently in design. Phase two construction is anticipated in the fall of 2004. Total project costs will exceed over $2 million; the project was awarded over $1.2 million in two Clean Ohio grants.
