Crawford Park District: Heckert Nature Preserve Wetland Creation

October 24, 2017 The Crawford Park District received a grant through The Nature Conservancy to enhance a farm ditch (a recently daylighted drainage tile line), that is a tributary to the headwaters of the Olentangy River in Crawford County. MAD Scientist Associates designed a flow-through wetland system that would receive both surface runoff and farm tile drainage. In MAD’s design, surface runoff is guided through a series of wetland step-pools before reaching the lower emergent marsh pool and mixing with the tile drainage in the southern half of the original ditch. This design optimized the wetland area and water quality enhancement opportunities, while eliminating the need for costly hauling of soils for off-site disposal. The high quality vernal pools in Heckert Nature Preserve, downstream of this water quality wetland, […]

Greenacres Foundation embraces wetlands for their environmental and educational benefits

October 24, 2017 MAD has been working with the Greenacres Foundation, a non-profit environmental education and sustainable farming organization in Cincinnati, Ohio, on two exciting wetland projects. Earlier this year, MAD designed and oversaw the construction of a treatment wetland to reduce nutrients in runoff from within and around their cattle weight house. A multi-cell wetland system was created to encourage sedimentation, colloid removal, nutrient sequestration (in plants and soils), and infiltration, before this facility runoff enters a tributary feeding Sycamore Creek. We are also pleased to report that Greenacres has broken ground on another wetland project near their education building. This one, a failed farm pond, turned emergent marsh, will be restored and expanded for Greenacres to use as an outdoor education site. Our team […]

Residents of Kendal at Oberlin enjoy wetland enhancement

October 24, 2017 We were pleased to get our hands dirty during the final phase of the Kendal at Oberlin wetland enhancement. This was our first major planting event of 2017, with the installation of over 4,000 native wetland and prairie plugs (28 species)! Work on this 2-acre wetland enhancement began in late 2015 with a delineation and permit application. In 2016, the design was completed and put out to bid. Wildlife was relocated to other wetlands within the Kendal property in preparation for earthwork. That October, the wetland basin was shaped and planted with native seed, shrubs, and trees. The basin was completely filled by February of 2017.  Residents of the Kendal community have enjoyed monitoring the wetland’s development, and will soon have a beautiful view […]
