Project Design and Construction Standards i. Driveway Detail 1 (32-foot width, 25-foot radius) for: 1. Service Stations; 2. Commercial Sites (over 800,000 square feet); 3. Office/Institutional Complexes (over 100,000 square feet); 4. Apartment/Condominium Complexes (over 200 units); 5. Mobile Home Complexes (over 200 lots). ii. Driveway Detail 2 (28-foot width, 25-foot radius) for: 1. Commercial Sites (80,000 square feet or less); 2. Office/Institutional Complexes (100,000 square feet or less); 3. Apartment/Condominium Complexes (199 units or less) 4. Manufactured Home Developments (199 lots or less). iii. Driveway Detail 3 (32-foot width, 40-foot radius) for: 1. Industrial Sites iv.

Along any major thoroughfare, a deceleration lane or acceleration lane, larger turning radius, traffic islands, or other devices or designs may be required to avoid specific traffic hazards which would otherwise be created by the proposed driveway location. 4. Corner Sight Distance. All driveways approaching a minor collector or major thoroughfare shall provide adequate corner sight distance. The minimum corner sight distance from the driveway shall be equal to or exceed 10 times the regulated speed of the intersected street, as measured from the centerline of the driveway in both directions along the right-of-way line of the intersected street. As an alternative, the minimum corner sight distance requirement may be calculated using AASHTO Policy on Geometric Design of Highways and Streets, Chapter 9 (at-grade intersections), latest edition. The sight distance shall provide clear visibility of an object four feet above the intersected street viewed from the centerline of the driveway at the right-of-way line of the intersected street, at a height of 3.5 feet above the ground. 5. Separation and Spacing. For Separation and Spacing refer to Georgia Department of Transportation’s (GDOT) Regulations for Driveway and Encroachment Control document.
