Green Open Space Design, Based on Disaster Mitigation Approach in Bulak Coastal Settlements

Abstract

Residential areas that directly border their coastline have a significant risk of natural disaster. One of them is the tidal flood disaster that threatens throughout the year, so that it greatly affects the activities of residents who mostly work as traditional fisherman. Based on the result of previous research, it was recorded that several tidal floods occurred within a period of one year which resulted in seawater inundation in residential areas, a significant decrease in the elevation of the sea wall and damage to traditional fishing boats, the impact of tidal floods was exacerbated by the phenomenon of significant increase in the number of houses that exceeded the land boundaries according to the designation of space. The Kejawen Lor area, Bulak District, is the coast of Surabaya City, which is prone to tidal floods. According to Presidential Regulation No. 51 of 2016, the safe distance between the shoreline and residents houses and also the arrangement of open spaces for evacuation and circulation are currently considered not to meet safety and feasibility standards. Through qualitative research, we want to find effort to prevent and reduce the negative impacts after the tidal disaster in the Kejawan Lor area to provide design proposals for improving the sea wall infrastructure and arranging green open spaces to beautify the area. Through field observations, general identification, sectoral area mapping and technical studies are carried out which are expected to produce a safe and habitable artificial environment.
