Abstract
Nowadays, the quality of green open space in urban settlements is gradually decreasing because of land use changes as well as new building construction. Moreover, urban community is often facing risk of river flooding and rainwater puddles during the rainy season. The purpose of this research is developing an urban open space network with function to managing rain water in settlement areas in Manado city. The WSUD planning principles is analysis as research variable and open space areas are defined into four type’s namely public zone, semipublic zone, semi private zone and private zone. This open space zones is considering into two main aspect, first the user of space (private or public) and next the decision maker (individual, groups, local government). The planning concept for urban settlement areas sensitive to water can be achieved by approaching three development types: open space network, buildings layout and streetscape.
Highlights
As a result of the impact of global climate change, Manado is facing increasing risks of flooding during the rainy season
While the aim in the adaptation strategy is the provision of urban drainage systems that is environmentally friendly and implementation of technology of drainage system to anticipate the impact of changes in extreme rainfall such as absorption wells, perforated drain, retention ponds and rainwater harvesting under a green open space
To support the local and central government, this study aims to integrate sustainable drainage systems on the means of green open space in city’s living environment
Summary
As a result of the impact of global climate change, Manado is facing increasing risks of flooding during the rainy season. The mitigation policies implemented into several development program and activities, namely: infiltration wells and biopori, rehabilitation of drainage system, controlling rainwater puddle (basin retention, polder, pump), arrangement of buildings and healthy living environments (flats, green open spaces, garbage disposal system) and more. While the aim in the adaptation strategy is the provision of urban drainage systems that is environmentally friendly (eco-drain and independent drainage) and implementation of technology of drainage system to anticipate the impact of changes in extreme rainfall such as absorption wells, perforated drain, retention ponds and rainwater harvesting under a green open space. This paper will discuss the strategy for the development facilities of settlement’s green open space in Manado as part of the management system of rainwater.
