Passau Island - An Introduction
Passau Island is the largest land reclamation project ever undertaken in Perseus and at 10km2 it's also one of the largest artificial islands in the world.
The location was selected due to the shallow waters and presence of an existing sandbank atop bedrock and it's proximity to Passau and the existing business district of Caledon Quay. Construction started in 2004 and was financed by primarily by the Persusian Government and Perseus Sovereign Wealth Fund. Significant investment was also leveraged from the private sector and sale of development plots.
Perseus is a seismically active region and this was factored into the design and construction of Passau Island. The existing sandbank was build up before being reinforced by means of densification, piling into the bedrock and the installation of innovative earthquake drains to combat liquefaction. The island also has a sophisticated surface drainage network to ensure surface water during wet weather is managed efficiently and effectively.
Passau Island was officially dedicated on 16th August 2014 by His Imperial Highness Prince Julius where he presided over an official ground-breaking ceremony and the dedication of a cornerstone for the Imperator Tower which is the tallest building on Passau Island.
Passau Island has also been designed with rising sea levels and an increasing number of tidal surges in mind. The entire island is ringed by a park which has been planted with trees and plants which can survive flooding events and contamination of the soil by sea water using an innovative freshwater flushing system to remove excess salt. The park also acts as sacrificial land in times of storm surge flooding and when combined with the barriers at full height affords protection of over 25 metres.
The barriers operate in conjunction with a series of sea buoys and a ring of various hydrological sensors that tell the system when to raise and lower the barriers. The barriers can operate at various heights up to a current maximum of 10 meters. When they aren't in operation the barriers are hidden within the quay embankment and don't restrict access in any form.
Passau Island is a landmark project delivering 25,000 new apartments with residential amenities, 50 million square feet of new office, retail and leisure space, landmark cultural attractions, new cruise terminal, marina facilities, expansion of Passau Metro and significant additional infrastructure investment.
