Chapter 12 : Miscellaneous Planning Standards & Guidelines


The purpose of this chapter is to provide planning standards and guidelines for those land uses or facilities which do not fall within the purview of other chapters.


The standards for these miscellaneous uses/facilities are :



Rock Cavern Development


  • no set standard

  • pre-feasibility studies and planning assessments are required prior to project planning

Petrol Filling Stations (PFS)


general site dimensions of new stations

  • minimum size :

    PFS without LPG facilities - 375m2

    LPG filling station - 375m2

    PFS with LPG facilities - 750m2

  • minimum frontage : 25m

  • minimum depth : 15m (including footway)

  • minimum width of access : 6m


site dimensions of stations with container vehicles patronage

  • minimum frontage : 40m
  • minimum depth : 15m (including a 3m footway)
  • minimum width of access : 8.5m


siting on Expressways

  • at least 2 km from any intersection
  • preferably form part of a service area


siting on Trunk Roads, Primary Distributor Roads and Rural
Roads A

  • minimum sight distance of 100m
  • minimum interval of 5 km


siting on other roads lower in the hierarchy

  • minimum sight distance of 50m
  • minimum interval of 100m if located on different sides of the road
  • minimum interval of 300m if located on the same side of the road


waiting spaces

  • 1 vehicle space adjacent to each metered filling point
  • minimum 4 waiting spaces between the entrance and the filling points
  • additional 4 spaces for each service bay if general lubrication and servicing facilities are available
  • 1 additional space between each air-pumping point


environmental and fire safety considerations

  • preferably be located in relatively open areas
  • avoidance of noise and air disturbances
  • covering of facilities for carwashing, petrol filling and maintenance activities, as well as car servicing and lubrication bays
  • provision of adequate petrol-intercepting facilities
  • provision of proper drainage facilities
  • proper storage and disposal of chemical wastes
  • compliance with fire safety requirements
  • provision of fire hydrant within 100m


general separation distances of LPG filling station/facilities

  • high-rise residential/education/hospital : 55m
  • commercial/recreational/industrial : 15m
  • low density residential/incidental dwelling : 15m


PFS within buildings
PFS (without LPG filling facilities) may be accommodated on ground floors of carpark, industrial or commercial buildings subject to :

  • station completely separated from other parts of building by enclosures with fire resistance period of 4 hours

  • site open for ventilation on one of the longest sides or two adjoining sides

  • adequate headroom and ventilation

  • floor area above to be used for occupancy with low fire/life risk

  • openings and windows on three levels directly above should be bricked up

  • Quantitative Risk Assessment and necessary planning approval

Potentially Hazardous Installations (PHI)


  • no set standard
  • a consultation zone will be delineated for each PHI according to the topography, types of PHIs and their storage capacities
  • Hazard Assessment, Planning Study and Action Plan would be undertaken as the basis for land use planning and development control within each consultation zone.

Vehicle Repairing Workshops


  • in rural areas

    • low rise building of 1 to 2 storeys

    • maximum plot ratio of 0.5

    • proper water supply and sewage disposal system

    • adequate paving and drainage facilities

    • suitable fencing as visual screen
  • in purpose-designed buildings or on the lower floors of industrial buildings

    • minimum size of 90m2 (10m x 9m)

    • include a dangerous goods store

    • access ramp of gradient 1 in 5 for cars

      inner radius 3.5m

      outer radius 6.1m

    • access ramp of gradient 1 in 10 for goods vehicles

      inner radius 7.2m

      outer radius 13m

    • minimum 1 car lift (minimum 6.15m x 3.2m)

    • mnimum 2 fire stairs (minimum 5.25m x 2.1m)

    • 5.2m floor to floor heights for cars and 7.2m for lorries

    • access point at least 15m from street corner

    • 0.75 parking space per workspace(1) or minimum 2 parking spaces per workshop

      cars : 5.0m x 2.4m with minimum 2.4m headroom

      goods vehicle : 11.0m x 3.5m with minimum 4.1m headroom

Port Back-up and Open Storage Uses

minimum site requirements

  • 5 100m2 for container storage and repair

  • 4 900m2 for container yard

  • 3 000m2 for container lorry park

  • 2 000m2 for container freight station

  • 1 000m2 for other open storage uses

Use of Land beneath Flyovers and Footbridges

  • No set standards

  • Flyover/footbridges sites should only be considered as alternative solution space for uses upon exhausting all other suitable sites, provided that such uses are acceptable in terms of land use, structural, fire safety, traffic, environmental, visual and all other relevant considerations

  • Uses beneath flyovers/footbridges are classified as acceptable, conditionally acceptable and unacceptable uses 

  • Relevant works departments should include the requirements for identification of possible land uses beneath flyovers/footbridges in the Investigation Stage of new major flyover/footbridge projects after inclusion into Category B of the Public Works Programme

  • Application of the guidelines may be adjusted subject to the exact nature of use, locality of the site, design of the flyovers/footbridges and other relevant considerations

   (1) workspace refers to an area large enough to accommodate a vehicle and the person working on it.
