What infrastructure needs must be addressed before subdivision approval?

Before a planning authority grants subdivision approval for industrial land, developers must demonstrate that core infrastructure can support each subdivided lot. This includes road access, utility capacity, drainage systems, and public safety provisions. The infrastructure must be designed according to local zoning codes, engineering standards, and regulatory conditions.

Below are the key infrastructure components that must be addressed before obtaining subdivision approval:

1. Internal Road Network

• Requirement: Design a road grid or loop serving all plots.
  
• Standards:
  
  • Minimum road width: 12–18 meters, depending on zoning and vehicle type.
    
  • Appropriate turning radius for trucks (typically 12–15 meters).
    
• Considerations:
  
  • Entry and exit points for traffic flow
    
  • Connectivity to a public road or highway
    
  • Pavement design for heavy loads

2. Stormwater Drainage and Flood Management

• Requirement: On-site stormwater collection and discharge planning.
  
• Elements:
  
  • Open or closed drain networks along roads
    
  • Retention/detention ponds or recharge pits
    
  • Proper outfall connected to public storm drains
    
• Compliance: Must handle peak rainfall events (1-in-25 to 1-in-50 year storms).

3. Water Supply and Sewerage Planning

• Requirement: Water line layout to serve each lot with adequate pressure and volume.
  
• Infrastructure:
  
  • Overhead tank or connection to municipal/industrial water supply
    
  • Internal water distribution pipes with isolation valves
    
  • Sewer lines or provision for/Sewage Treatment Plant (STP)
    
• Regulatory: Conforms to Pollution Control Board and municipal water board norms.

4. Electrical and Communication Utilities

• Requirement: Distribution infrastructure for high-tension and low-tension electricity.
  
• Elements:
  
  • Power line trenches, feeder points, and transformer locations
    
  • Street lighting layout
    
  • Space for future 5G/fiber optic cabling
    
• Provisioning: Redundant capacity planning is encouraged for industrial usage.

5. Fire and Emergency Access

• Requirement: Adequate road width and layout for fire truck movement.
  
• Design Features:
  
  • 6–9 meter clear emergency lanes where applicable
    
  • Turning radius and fire access around larger plots
    
  • Dedicated fire water storage (if required by zoning)
