ARC/Franklin Street Drainage Improvements
BLN led this large-scale, quick schedule project for ARC Development/Franklin Street drainage improvements, which provided a new dedicated storm sewer system for a 71-acre drainage area. BLN designed the storm sewer system to include 3,300 linear feet of large diameter concrete interceptor pipe ranging in diameter from 36 inches to 96 inches. The stormwater interceptor, which begins at the (then proposed) ARC Development, is routed northwest along High Street, Adams Street, Franklin Street, and Washington Street in downtown Muncie before discharging into the White River. The overall design allows the Muncie Sanitary District to support future phases of separate stormwater improvements.
The project, a functional canal feature and landscaped recreation area was located along the east side of Liberty Street between Washington Street and Gilbert Street. Approximately 60 inlets and an additional 2,700 linear feet of small diameter pipe were installed along the project corridor to collect stormwater and direct the runoff to the interceptor and canal. BLN engineers designed the canal and the individual inlets to function as best management practices for water pollution control measures.
McKinley Retention Pond Pumping Station
BLN was part of the design team for a 1.7-million-gallon storm sewer retention pond pumping station and subsequent improvements in Muncie’s historic McKinley neighborhood. This 40-acre neighborhood was in disrepair due to chronic stormwater overflow during rain events. These reoccurring events required the MSD to act quickly to revitalize the McKinley neighborhood completely. The design addressed three key issues affecting the area:
- Modernize the 85-year-old Elm Street Levee to meet Army Corps of Engineers and FEMA standards to withstand a 10-year storm event, even if the adjacent White River was inaccessible during a 100-year flood event. This was accomplished by pumping pressurized captured flood water from behind the outdated levee through a 16-inch diameter water force main through the new levee.
- More than 40 storm sewer inlets were disconnected from the neighborhood and rerouted into the new stormwater retention pond to meet the requirements of the Indiana Department of Environmental Management mandate.
- Due to shallow bedrock during the pond excavation, engineers shaped the pond to fit the natural topography of the rock layer and reused excavated boulders and native tree plantings around the pond perimeter. Existing trails were extended into the levee area to provide connectivity, encourage increased use of the green space, and spur neighborhood revitalization. Additional improvements in the McKinley neighborhood included curbs, sidewalks, fencing & preemptively installed signage to protect vehicles and pedestrians.
