Abstract

 ‘Living on the water’ is an ancient urban settlement concept, generally applied in front of existing coastal urban expanses (along sea, river lake shores), which are conditioned to expand into the ‘watery environment’  because of exhaustion of buildable land resources, or because of security reasons or pursuit of environmental attractiveness, or the combination of those.

Settlement and urban expansion of coastal metropolitan regions with rising density, through ‘land reclamation’ projects and conquest of the sea, mostly because of the subsequent rising real-estate costs on land, degradation of the infrastructures and environmental collapse, are turning into a global trend, posing as a techno-economic and engineering challenge, attracting mounting social-political attention and allocation of increasing financial resources.

To achieve greater economical viability and applicability much higher densification levels of the urban fabric have to be adopted: ‘The highest attainable density levels which still could be considered as environmentally attractive’ (Burt).

The ‘Tabula-Rasa’ condition of the developed marine space, free as it is from parcellation and land ownership pattern’s, from historical memories and preservation constraints and the evolutionary transportation grids, justify and enable adoption of an alternative urban planning and design paradigm, the essence of which is a far reaching densification, an alternative conception of development of  the ‘urban biotic mass’, incorporation of a channel grid to support environmental attraction and channel transportation and subsequently reducing the tyranny of the private vehicles over the urban space.

To reduce the dependence on bathymetric constraints of the coastal marine regions (of coastal cities) techno-engineered solutions of pile supported or even floating platforms and breakwaters are incorporated. The suggested technology  (fill material free) may generate a water channel system (to function as public open spaces, transportation boulevards and integral ‘marina’s).

All the technology modular components are to be solved for intensive industrial mass-production and for floatability, to be sea-transported and installed-assembled on the site.

These concepts, when realized, are techno-economically  and environmentally advantageous not just for the Israeli development reality, but for the international coastal metropolitan realities as well.

The issue is very multidisciplinary, combining urban-architectural, environmental, engineering and techno-economical aspects. The research makes use of extensive literature review and was helped with expert opinions on various relevant topics.
