The key environmental impacts from and documents that may be required for housing, office or commercial developments

Key environmental considerations

The key environmental impacts from housing, office or commercial developments include:

Development footprint

  • habitat damage (including bogs, heathlands, woodlands and low nutrient grasslands)
  • species disturbance and/or displacement
  • modification to waterways including alterations to existing crossing structures such as culverts and bridges within the site


  • impacts on surface water drainage run-off rates and the potential risks associated with surface water flooding

Pollution of water environment

  • potential for impacts on mains foul sewage capacity
  • risk of polluting discharges from septic tanks entering surface waters or groundwater
  • run-off contaminated by chemicals or sediment from stockpiles or site clearance works resulting from the release of inorganic compounds effecting water quality, aquatic ecosystems and fisheries

Documents/information required

The following lists the documents/information that may be required to ensure that DAERA can provide a substantive response:

Development details

  • site access arrangements
  • position of all buildings and associated infrastructure.
  • details of proposed method of sewage disposal/location of septic tank or treatment plant
  • site Drainage Plan


Ecological e.g.

  • habitat
  • priority/protected species


  • Pollution Prevention Measures during construction
  • Species mitigation proposals
