Update: Work continues at the pump station on South Loop Road at Hartsfield-Jackson Atlanta International Airport. Contractors will be preparing slab area for geopier installation and clearing of detention pond. Once geopier installation is completed, contractors will start form work, rebar and concrete placement at the slab. Contractors will also install a storm pipe at the detention pond.   This project reinforces the integrity of services for which the Hartsfield-Jackson Water Distribution Facility was constructed. This will ensure availability of uninterrupted quantity and quality of water distribution to the airport. Expected Completion: June 2019 Project Location: South Loop Road, Hartsfield-Jackson Atlanta International Airport Council Districts: 11, 12 Neighborhood Planning Units: P, Q, R, Z

Clear Creek West Sewer Improvements Project Civic Center Vault

Update: Crews continue to pour the walls and foundation of the vault. In addition, crews will tie- in rebar and pour columns and slabs.   The City of Atlanta Department of Watershed Management has identified the need for an underground storage vault to be installed to increase the storage capacity of the existing combined sewer system in the Clear Creek West basin. The vault associated with this project is located in the southeastern corner of the existing Civic Center parking lot adjacent to Ralph McGill Boulevard. The Butler Street trunk and relief combined sewers drain the upper section of the west Clear Creek basin. During certain rainfall events this system can become surcharged, which may result in flooding. The storage vault will store excess combined sewer flows from the Butler Street Relief Combined Sewer, which intercepts at the I-75/85 entrance ramp from Freedom Parkway and Highland Avenue. Stored combined sewer flow in the vault will reduce the peak flow in the downstream combined sewer helping to reduce flooding.   This stormwater vault will help manage rainfall runoff from the adjacent federal highways and downtown portions of the basin. Additionally, implementation of green infrastructure projects is proposed to further manage combined sewer peak flows to the combined sewer system and to reduce the required capacities of the vaults.   Expected Completion:  March 2019   Project Location: Northeast Atlanta   Council District(s): 2   Neighborhood Planning Unit(s): M, E

Upper Proctor Creek Capacity Relief Project Rodney Cook Sr. Park In Historic Vine City

Update: The Upper Proctor Creek Capacity Relief project: Rodney Cook, Sr. Park in Historic Vine City is a multi-phase effort to reduce flooding and combined sewer flows in the Vine City neighborhood.    This project consists of a collection of innovative stormwater practices designed to redirect surface runoff away from the Beckwith Trunk and Mineral Springs combined sewer systems.   The capacity relief facility is currently under construction led by the Astra/Rohadfox, Joint Venture.    The components of this project include a 2-acre pond (9+ MG capacity), green infrastructure (bioretention, stormwater planters, rainwater harvesting cisterns, and soil restoration), aerating water features, separated storm drain pipelines, new sidewalks and roadway improvements.    The Department of Watershed Management is working concurrently with The Trust for Public Land who is responsible for the build out of the adjacent park. In addition, The National Monuments Foundation will be constructing statues of historic figures throughout the finished park.   Expected Completion: April 2019 Project Location: Vine Street NW Council District(s): 3 Neighborhood Planning Unit(s): L

Upper Proctor Creek - Boone Boulevard Green Infrastructure & Capacity Relief Project

Update :  Due to the moratorium imposed on the City Of Atlanta for Super Bowl LIII , work on Boone Boulevard will be temporarily suspended from January 21, 2019 until February 11, 2019. In preparation for Super Bowl LIII, contractors will be installing pedestrian fencing alongside parts of Joseph E. Boone Boulevard NW, between Elm Street NW and Maple Street NW. Contractor will monitor traffic control and pedestrian fencing on Joseph E. Boone Boulevard NW during moratorium. After February 11, 2019, contractors will continue work on installation of planter boxes and replacing of water main on Joseph E. Boone Boulevard NW. This project will provide capacity relief to the North Avenue Combined Sewer Area and water quality improvements using the green infrastructure practice called bioretention, which is a specially landscaped area that captures runoff from an impervious surface and allows water to enter the soil. Proposed bioretention areas will span approximately 1.2 miles along Boone Blvd from Mayson Turner Road to Northside Drive that will collect stormwater runoff from along the sides of the road. Expected Completion: June 2019 Project Location: Northwest Atlanta Council District(s): 3 Neighborhood Planning Unit(s): L
