Kathryn Johnston Park to relieve flooding along Boone Boulevard

The newly named Kathryn Johnston Memorial Park in the English Avenue neighborhood in west Atlanta was redeveloped to help curb the persistent flooding of streets and homes that historically plagued this area. LONG designed the 3.2 acre park with Green Infrastructure to reduce the volume of stormwater that enters the 14’ diameter combined sewer that passes beneath the park property. This includes enhanced swales with weir walls to encourage ponding and promote infiltration, a stormwater planter on Oliver Street that overflows into a bio-retention area and two major water quality systems consisting of Stormtech Chambers encased in stone.

The Kathryn Johnston Memorial Park was developed by Park Pride, The Conservation Fund, and the City of Atlanta Department of Parks and Recreation and Office of Sustainability. Amenities will include a playground, fitness stations, and seating terrace.

Atlanta Memorial Park Conservancy Consulting

Long Engineering, Inc. was retained by the City of Atlanta Department of Watershed Management and the Atlanta Memorial Park Conservancy to provide technical input into the city’s approach to reducing sanitary sewer overflows, flooding and stream bank degradation within Peachtree Creek and Tanyard Creek that traverse the Atlanta Memorial Park property, including the Bobby Jones Golf Course.  The Peachtree Creek basin encompasses 94 square miles of urbanized portions of DeKalb County and the City of Atlanta.  This urbanization of time has continually taxed the aging infrastructure carrying sanitary sewer and stormwater through the basin.  LONG’s services included reviewing the city’s evaluation of alternatives to reduce wet weather sanitary sewer overflows within the Peachtree Creek basin, Capital Improvement Program priorities, combined sewer overflow treatment facility operations and basin hydraulic modeling.   The collaborative effort also included interfacing with City Council and the Mayor’s office.
