Newburgh Town Hall Bioretention Areas

Description

people planting and creating a bioretention area

Two bioretention areas were installed as a retrofit into the existing parking lot stormwater system. This project cut out the asphalt around two existing catch basins and re-formed the new asphalt surface to re-direct runoff to adjacent lawn areas. The bioretention areas were constructed in these lawn areas. Because the native soils were highly disturbed and generally tight-textured, gravel-encased underdrains were installed in the bottom of each to provide an "overflow outlet" for collected runoff in the event that the native soils under the practices are unable to infiltrate it all. In addition, the native soils were heavily amended with a sandy loam topsoil. Appropriate plants were established, while mulch, rocks and "dry streambed" features were added for visual diversity.

  • Size of drainage area: 7,200 square feel for each bioretention area
  • Plants or materials used: Carex, Cardinal Flower, Yarrow, Euonymus, Dayliliy, Turtlehead, Asters
  • Maintenance: Weed, water, replace plants, keep inflow devices clear of debris
  • Maintained by: Orange County Soil and Water Conservation District, Town of Newburgh
