Green Alley Reconstruction
To date, over 80 alleys have been completed. All remaining alleys in the Bee Branch
Watershed are scheduled to be reconstructed between 2029 and 2040. The specific construction
year for each alley has not yet been determined.
Estimated Completion: 2040
Green alley reconstruction focuses on reducing the volume of stormwater in the watershed. Traditional concrete, asphalt and packed gravel surfaces used to construct driveways, alleys and sidewalks are impervious. An impervious surface does not allow stormwater to soak into the ground. Instead, these types of surfaces create run-off that can exceed the capacity of the storm sewer system contributing to flooding during major rain events. To reduce the amount of impervious surfaces, approximately 240 alleys in the watershed will be converted to green alleys. Twenty-three alleys were completed in 2014, 28 alleys were completed in 2015, 21 alleys were completed in 2016, and one alley was completed in 2017. The remaining alleys in the Bee Branch Watershed are scheduled to be reconstructed between 2029 and 2040. The specific construction year for each alley has not yet been determined. This conversion is expected to reduce stormwater runoff from alleys within the Bee Branch Watershed by up to 80 percent.
