Civil Engineering Services in Atlanta, Georgia

Full-Service Site Development Engineering for Residential, Commercial, and Mixed-Use Projects in Atlanta

Atlanta is one of the fastest-growing metropolitan areas in the Southeast, with 19,000+ new residential construction permits issued across Metro Atlanta in 2025 alone. Rapid growth in mixed-use corridors like the BeltLine, Centennial Yards, and Midtown continues to drive demand for experienced civil engineering firms that understand the City of Atlanta’s unique regulatory landscape. Mack Engineering provides full-service civil engineering and site development services for developers, investors, and property owners building in Atlanta and across Fulton County.

What Civil Engineers Need to Know About Atlanta

• Atlanta’s Post-Development Stormwater Management Ordinance (Chapter 74, Article X) requires all new development and redevelopment to manage the first inch of rainfall through green infrastructure — a requirement that goes beyond state minimums and directly impacts site design.
• The city enforces a 75-foot riparian buffer along streams (Chapter 74, Article VII), significantly exceeding the state minimum of 25 feet. Revegetation standards require 198 to 348 trees per acre with native species, making buffer compliance a critical element of every site plan.
• Atlanta’s tree protection ordinance (Chapter 158) applies to all trees 6 inches DBH or greater. Specimen and heritage tree removal requires mitigation that can substantially affect site layout and grading design.

Land disturbance permits for projects exceeding 5,000 square feet of ground disturbance require Georgia-registered PE-sealed erosion and sediment control plans following Green Book BMPs. Submittals are processed through the city’s Accela online system.

Development Activity in Atlanta

Atlanta’s development market spans high-density mixed-use projects along the BeltLine, infill residential in established neighborhoods, medical office and commercial development, institutional campus expansion, and industrial warehouse projects near the airport and interstate corridors.
