“Following the Runoff” A category-conceptual project

Haifa city is famous for its mountainous topography and sharp slopes. So, retaining walls and stairs are inseparable part of urban landscape of Haifa.
Hadar neighborhood is one of the oldest parts of the city. It was built in the first part of previous century, that’s why the water removal system is quite old and is unable to cope with large amount of water in rainy winter. The neighborhood doesn’t have much infiltration area, so in heavy rain everything is flooded-streets and private house areas. The runoff is everywhere and it makes access to different places impossible.
This project uses public and semi-public places, like stairs and its adjacent area to target the flow of runoff, slow it down and enter the excess water into infiltration ponds. These infiltration ponds contain plants, which can stay more than 24 hours in stagnant water like: Agapanthus africanus, Iris pseudacorus, Acorus calamus, Cyperus papyrus, Nerium oleander and many other. These plants can filter the contaminated water. Under the plants there are different levels of sand and gravel that also filter the runoff and then, it joins the groundwater.
This infiltration system becomes a part of new public areas of Haifa, which makes its urban landscape definitely available and more useful for citizens.
