Driveways/Walkways
When constructing a concrete driveway that extends to a public right-of-way, specific requirements must be followed
1. Permits and Approvals
Permit Application: Obtain a driveway permit from the local city or county office.
Right-of-Way Authorization: Secure approval for any work performed within the public right-of-way.
---
2. Location and Design Standards
Driveway Alignment: The driveway should be positioned to avoid interference with utilities, street intersections, and existing drainage systems.
Driveway Width:
Residential: Commonly 10-20 feet wide.
Commercial: Width may vary based on use and vehicle type, often 20-30 feet.
Driveway Slope:
Ensure the slope complies with local guidelines, often no steeper than 2% in the right-of-way area to avoid water runoff into the street.

3. Construction Material Requirements
Concrete Thickness: Typically 4-6 inches for residential driveways; 6-8 inches for areas that support heavier vehicles.
Reinforcement: Reinforced with rebar or wire mesh to increase durability.
Surface Finish: A broom or non-slip finish is often required for safety in public access areas.

4. Drainage and Grading
Proper Drainage: Ensure that the driveway does not impede the natural flow of water or cause runoff to adjacent properties.
Culverts or Drains: If the driveway crosses a ditch or drainage channel, you may need to install a culvert to maintain water flow.

5. Setbacks and Clearances
Distance from Property Lines: Maintain required setbacks from adjacent properties, usually 5-10 feet.
Utilities: Ensure clearance from underground utilities and utility poles. Call your local "Call Before You Dig" service to locate utilities.

6. Transition to the Street
Apron Design:
The transition between the driveway and the street (the apron) must comply with local standards.
Apron material is often specified (e.g., concrete, asphalt).
Curb Cut: If a curb exists, obtain approval for modifications, such as a curb cut or ramp.
---
7. Traffic and Safety Considerations
Visibility: Ensure the driveway does not obstruct visibility for drivers, pedestrians, or cyclists.
Markings: In some areas, reflective or warning markers may be required near the driveway's edge.
---
8. Inspection and Compliance
Inspections: The local building authority may require inspections at various stages of construction.
Final Approval: Ensure the finished driveway meets all local standards before it is officially approved for use.

Since requirements can vary widely based on your location, consult with your local Department of Public Works, zoning office, or a licensed contractor for specific guidelines and regulations applicable to your area.
