Capital Improvement Program Construction Brief May 2018

Active Construction

Water Supply Program: Quarry/Chattahoochee/Hemphill Update: Excavation continues and contractors are rebuilding the existing pump station at the R.M. Clayton Reclamation Center, which is located at 2440 Bolton Road NW. Construction of two new pump stations also continues at the Bellwood Quarry and the Hemphill Water Treatment Plant sites. The tunnel boring machine has reached the three mile mark. Two miles of tunneling remains to complete the five mile path to reach the Chattahoochee River. Controlled blasting is necessary to complete the construction shaft and a short tunnel connecting the shaft to a proposed Chattahoochee River Intake pump station. The Water Supply Program will increase Atlanta’s reserve water supply from three to five days to 30 to 90 days. The $300 million investment includes the construction of a five-mile tunnel connecting the Chattahoochee River, the Hemphill Water Treatment Plant, and the former Bellwood Quarry, which will be transformed into a 2.4 billion gallon reservoir. The Water Supply Program is scheduled for completion by September 2019. Expected Completion: 9/2019 Project Location: Northwest Atlanta Council District(s): 3, 9 Neighborhood Planning Unit(s): C, D, G, J, K

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

Update: Watershed Management contractors are continuing soil remediation work on the Cook Park site. Crews completed decommissioning the water line at Vine Street NW and Thurmond Street NW. The project is designed to help alleviate flooding while providing increased greenspace in Vine City. The project consists of installing a new capacity relief storage facility in the area, installing 2,200 linear feet of 60-inch capacity relief trunk line, re-routing 1,100 LF of 96-inch combined trunk sewer by installing pipeline in the right-of-way along street in the Vine City area and remediating and relocating sewers.  Expected Completion: 12/2018 Project Location: Northwest Atlanta Council District(s): 3 Neighborhood Planning Unit(s): L

R.M. Clayton Sand Filter Media Installation and Refurbishment Project

Update:  90 percent of media has been installed with 100 percent of media delivered. 95 percent of media has been turned over to the City and the effluent channel is100 percent complete. The air pattern test for filter 4 is complete and the project is ahead of schedule and within budget. The R.M. Clayton WRC treatment process removes biological and chemical impurities from the wastewater in three phases: primary treatment, secondary treatment and tertiary treatment. Primary sludge and biological solids that are removed during the wastewater treatment process are reduced in the digestion process before being dewatered and incinerated or hauled to a landfill. This project will restore the effectiveness of the filtration process, reduce the backwash frequency and duration, reduce the maintenance costs and improve overall plant reliability in meeting permit limits. The project is estimated to be completed in June 2018.   Expected Completion: 6/2018 Project Location: R. M. Clayton Water Reclamation Center Council District(s): 9 Neighborhood Planning Unit(s): D

Upper Proctor Creek Boone Boulevard Green Infrastructure

Update : Water mains are tentatively scheduled to be replaced in the second quarter of 2018 on Joseph E. Boone Boulevard NW between Northside Drive NW and Mayson Turner Road NW. Stormwater planter boxes, sidewalks, driveway aprons and tree installations have been completed along the southern side of Joseph E. Boone Boulevard NW between Joseph E. Lowery Boulevard NW and Sunset Avenue NW. Now under the project, DWM will replace water mains on Joseph E. Boone Boulevard NW between Northside Drive NW and Mayson Turner Road NW. Water main replacement work is currently tentatively scheduled to begin early 2018.  Expected Completion: TBD Project Location: Northwest Atlanta Council District(s): 3 Neighborhood Planning Unit(s): K, L, M

Cascade Road Water Main Installation

Update: Crews have completed connecting water service lines to the new eight-inch water main and are now performing leak repairs and concrete work. Eight-inch water main installation work is continuing on Cascade Road SW between Childress Drive SW and Beecher Street SW, resulting in a temporary westbound lane closure. Expected Completion: 5/2018 Project Location: Southwest Atlanta Council District(s): 4, 10, 11 Neighborhood Planning Unit(s): S, R, I

Clear Creek West Sewer Improvements Project

Update: Contractors are currently conducting soil and water tests and analyzing the samples. In addition, crews will continue laying foundation, building walls, decking and installing rebars.   The City of Atlanta's 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 the Butler Street Trunk Combined Sewer 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 are proposed to further manage combined sewer peak flows to the combined sewer system and to reduce the required capacities of the vaults.   Expected Completion: 7/2018 (Design Phase) Project Location: Northeast Atlanta Council District(s): 2 Neighborhood Planning Unit(s): M, E

Clear Creek Combined Sewage Control Facility Package 1, Chemical System Improvements and Flow Monitoring

Update: Refurbishment of two storage tanks at Clear Creek CSCF is complete. The remaining two tanks are scheduled to be refurbished in June. Contractors are finishing Phase 1 of installation of new chemical feed piping at the Clear Creek Combined Sewer Control Facility (CSCF). A manhole has been set to install a flow meter at the CSCF at Tanyard Creek. The drum screen at Custer Avenue CSCF has also been rebuilt. The project is approximately 35% complete.   Clear Creek Combined Sewage Control Facility (CSCF), one of the combined sewer control systems owned and operated by the City, is located in the west service area. During large storm events, when the capacity of the tunnels and the West Area WQCF is exceeded, the combined flows enter the Clear Creek CSCF and the combined wastewater is treated through coarse bar screening and fine drum screening, disinfected with sodium hypochlorite (NaOCl) and dechlorinated with sodium bisulfite. Upgrades to the NaOCI storage tanks, pump and piping system will improve system reliability. Various improvements to other water quality control facilities (WQCF) are included in the project.   Expected Completion: 3/2019 Council District(s): 2, 3, 5, 6, 7, 8, 9 Neighborhood Planning Unit(s): A, B, D, E, F, G, H, K, M, O

Neighborhood Planning Unit (NPU) The City of Atlanta is divided into 25 Neighborhood Planning Units (NPU), which serve as citizen advisory councils that make recommendations to the Mayor and City Council on zoning, land use, and other planning issues. NPUs also allow citizens to receive information about all functions of city government.
