The development's drainage plan required the construction of lagoons designed to collect surface water to prevent flooding and water damage to infrastructure.
The construction of the lagoons was a risk to the airport as:
Air safety is paramount at airports and Stansted has a bird hazard management plan to safeguard air traffic. Legislation also requires risk to be assessed and monitored within a 13km radius of an airport. This applies to newly proposed and developments as well as existing infrastructure.
A solution was required to mitigate the risk of increased bird activity due to a development in the 13km safeguarding zone around Stansted Airport.
Safeguarding the lagoons from birds
Having identified the risk at the planning stage our specialist birdstrike management team recommended and installed a bird proofing system to prevent bird species accessing the lagoon. Bird species we frequently deal with at this type of location include gulls, crows, jackdaws, pigeons, waterfowl and other ground nesting birds. Although an urban environment, the nature of the environment provides natural habitat and opportunity which attracts birds for breeding, feeding and roosting.
The bird proofing system involved netting off the 50m x 35m lagoons. The posts were installed at a low level to minimized their visual impact and the net was secured to tensioned cables to ensure the netting system remains effective.
The installed bird proofing solution will:
A net maintenance plan protects the investment and ensures the system remains effective year on year.
