In-house civil engineering means Mack Engineering LLC, a licensed Georgia engineering firm, performs the grading, stormwater, utility, and permitting work on our projects rather than subcontracting it. Plan review comments get revised and resubmitted the same week instead of sitting in an outside consultant’s queue, and design and construction decisions are made by people who talk daily — a coordinated, refined approach that keeps your project vision consistent.

Our civil engineering services

• Feasibility Reports — what a parcel will actually yield, before you buy or invest.
• Concept Site Plans — early layouts that test unit count, access, and buildable area.
• Zoning Exhibits & Reports — the graphics and analysis that carry a rezoning or variance through a hearing.
• Land Disturbance Plans (LDP) — the permit set that lets grading legally begin.
• Grading Plans — cut, fill, and finished elevations engineered to balance on site where possible.
• Sanitary Sewer & Septic Designs — gravity sewer, pump stations, and on-site systems with primary and reserve fields.
• Erosion & Sediment Control — Georgia-compliant plans and NPDES permitting support.
• Land Planning — subdivision and lot layout that maximizes yield within the code.
• Civil Engineering — sealed construction plans for site, utility, and infrastructure work.
• Stormwater & Hydrology Design — detention, water quality, and hydrologic modeling.
• ADU Designs & Engineering — accessory dwelling layouts and the site work to support them.
• Autodesk Revit Modeling — 3D coordination and clash detection on every project we design.
