Scope of Work

Landfill and Airport Slope Mowing and Clearing

Scope: On behalf of the City of Atlanta, the Department of Aviation (DOA) and the Department of Public Works (DPW) seek a qualified contractor to provide specialized mowing, vegetation control, and clearing services at designated City-owned properties. These services must include the mowing of heavy brush and saplings on steep slopes; removal of vegetative and land debris (via mechanical clearing or herbicidal application); fence line clearing; and sediment removal from culverts and ponds, as required by the Georgia Environmental Protection Division (EPD) and the Federal Aviation Administration (FAA). All services must be performed in a manner that ensures positive drainage and allows for the free flow of water consistent with the natural topography of air and landside areas, sediment ponds, and landfill slopes.

Purpose: This scope of work outlines the complete responsibilities and performance expectations for the selected contractor. The contractor must deliver specialized services, including the mowing and clearing of heavy bush, trees, and saplings on steep slopes; removal of vegetative and land debris; treatment and clearing along fence lines and guardrails; stump grinding and removal; and the clearing of sediment from culverts and stormwater ponds. All work must comply with applicable regulations from the Georgia Environmental Protection Division (EPD) and the Federal Aviation Administration (FAA). All services must be executed in a manner that promotes positive drainage, enabling water to flow freely in accordance with the natural topography across airside and landside areas, stormwater retention systems, and landfill slopes. Mowing and clearing of steep slopes must also comply with FAA wildlife hazard control requirements under FAA Regulation Part 139.337, which mandates immediate mitigation actions upon identification of wildlife threats. Such threats include excessive vegetation near runways, taxiways, retention ponds, and other airport environments. In alignment with FAA Part 139.337 and TSA Part 1542, additional locations beyond the Security Identification Display Area (SIDA) will require slope, sediment, and vegetation clearing.

Wildlife Hazard Response Procedures:

In accordance with FAA Regulation Part 139.337, contractors must immediately halt work upon identification of any wildlife hazard that poses a potential safety or operational risk. The contractor shall promptly notify the designated Airport Operations representative and the Landfill Manager.

This restriction does not apply to Department of Public Works (DPW) right-of-way or non-landfill areas where separate approval and guidance will be provided by the respective authorities.

Vegetation Treatment Approval Process:

All chemical vegetation control applications must receive prior written approval from the Landfill Authority before use. Approvals are contingent upon analytical testing conducted under the State of Georgia’s Groundwater Protection Standards (GWPS). The standard turnaround time for analytical testing and approval is a minimum of three (3) weeks from the date of submission.

Contractors must plan and submit all required documentation in advance to prevent disruption of scheduled work and to ensure compliance with environmental and safety regulations.

•Conduct traffic control and verify underground utilities using provided site construction drawings before performing any work.

Underground Utility Location Coordination:

Contractors will be granted access to all applicable construction drawings and site plans, which clearly identify the elevations and locations of both above-ground and below-ground utilities. It is the contractor’s responsibility to review these documents prior to any excavation, mowing, or clearing activities. All utility locates must be confirmed and documented before commencing work in each area. Contractors are fully responsible for any damage resulting from failure to comply with utility location protocols.

Utility Location and Damage Liability:

Contractors will be granted access to review all landfill blueprints and site plans, which indicate both above-ground and below-ground utility elevations and infrastructure layouts.
