Water Sensitivity In The Context Of
                                     Climate-Friendly Urbanism

               A  great  deal  of  the  surface  areas  in  the  cities  is  public  green  areas.  For
            instance, 68% of Oslo, 45% of Vienna, 7,5% of Tokyo are composed of green
            areas. When water is taken into consideration, cities can not only bring nature
            and water and humans together, but can also direct the water in the city to parks
            in a sustainable manner, without many construction items for gray infrastructure.
            When this happens, this means not just exhibiting a more ecological approach,
            but producing more economical and efficient solutions. A case in point is a study
            implemented in New York. The study revealed that as New York maintained
            rainwater management through gray infrastructure, the upgrades that the city
            had to make in 2010 required a 6.8-billion-dollar investment. However, it has
            been observed that an improvement made through the combination of gray
            and green strategies reduces this cost by 1.5 billion dollars.
               In countries like ours suffering from water scarcity, supplying the groundwater
            is gaining importance. The retarding basins and other nature-based solutions
            (such as rainwater gardens, bio-swales, filtering lines, etc.) maximize benefits
            in the long term as they allow water to seep in the ground slowly. For instance,
            in Tujunga Wash Greenway, Los Angeles, water brought to the park forms a
            meandering corridor, pouring into this basin and throughout its journey, its
            slows down and evaporates to the sky and seeps into the ground to support
            the water layer underground.
               The maintenance of parks is always costly. For this reason, the rainwater
            management techniques that cost the highest are water storage and capture
            structures,  followed  by  retarding  basins,  biological  water  capturing  ponds
            respectively, and permeable surfaces that cost almost the same as ponds, and
            finally swales with vegetation that cost the lowest (Figure 2). It can be said that
            shallow dikes full of pebbles and grass can also be at the bottom of the list in
            terms of cost (TPL, 2016).
