Cullen Park is uniquely located at the confluence of the Maumee River and the western basin of Lake Erie within the 100 year floodplain of the Maumee River watershed. Influenced by seasonally fluctuating water levels, off site storm water sources, and on site development, this 36-acre park is Ohio's western-most public boat access site to Lake Erie and the lower reaches of the Maumee River. It serves as a popular passive recreation site, bird watching venue, and Best Management Practices demonstration site. The Great Lakes nearshore areas are valuable ecological and economic resources that provide drinking water for municipalities and critical habitat for numerous species of birds, fish, and other aquatic life. Storm water from rain, snow, or ice melt can evaporate, soak into the soil, or run off into nearby waters; in natural landscapes, soil and plant material absorb and hold much of it, but in developed environments storm water contributes to flooding and water pollution as pollutants deposited on impervious surfaces are rapidly conveyed to waterways by traditional drainage systems. To address these problems, a Maumee River Best Management Practices project at Cullen Park was funded through a $300,000 U.S. EPA Great Lakes Initiative grant to demonstrate alternative green infrastructure storm water management techniques that manage runoff, improve biodiversity, and increase public awareness of practices that improve water quality and biological function within the watershed. Conducted in an Area of Great Lakes Water Quality Concern, the project was intended to support the goals of the Maumee Area of Concern Stage 2 Watershed Restoration Plan, the 2011-2015 EPA Strategic Plan, and the GLRI Action Plan. Best management practices installed at the site include preservation of existing vegetation, vernal pools, boardwalks, rip rap outlet protection, vegetated filter strips, rigid L.I.P. level spreaders, vegetated swales, naturalized prairie and tree plantings, wetland preservation, and gravel verge. The total project area is 9.21 acres, including 8.09 acres of existing open space, with storm water from 1.2 acres of on-site paved areas and 5.3 acres of off-site residential areas, and the retention capacity of the vernal pools and other green infrastructure elements exceeds an estimated 650,000 gallons.
