Jakarta’s dense population has caused a disorder in the urban system by negatively impacting its streams. Therefore, this research aims to find out the urban district design criterias with rainwater harvesting system and how to implement them in residential areas of Kebon Melati, Tanah Abang. Data collecting techniques used in this research include literature studies, field observation, and interviews. The proposed solution to Jakarta’s rainwater problems is to design a district which incorporates the four potential urban design theory applications into it. The first theory is about land use related to storage and drainage system. The second theory is about vehicle circulation and pedestrian paths related to roadblock gaps and permeable materials. The third theory is about building mass and shape related to catchment area, conveyance, and green roof. The last theory is about open spaces related to water retention basins. The goal of this urban district design is to develop and decrease the speed of rainwater flow in Kebon Melati.

Method Of Design

On-site stormwater detention is widely used in Australia as a means of controlling the increased storm discharges from urban consolidation projects. However, unless the maximum permissible site discharge is correctly determined, the local piped drainage system may be overloaded. This paper presents a generic methodology that integrates detention storage behaviour with drainage design theory in such a manner as to protect the entire length of the downstream drainage system. Its generic nature facilitates its universal application to all systems, protecting these valuable community assets throughout their service lives.

This study was conducted to assess the building coverage and environmental quality of residential area in Nkpor Uno Idemili North L.G, Nigeria. The study employed a descriptive survey design to find out level of compliance of buildings to planning regulations. One hundred and eighty (180) were interviewed using a modified instrument (questionnaire). The data collected were coded into SPSS and analyzed with descriptive statistics. The results showed that 72(40%) reported inadequate setback as a major effect of over built buildings, 55(30.6%) reported inadequate free air space, 37(20.6%) said inadequate ventilation and lighting. Also, the nature of drainage system provided in residential areas; 76(42.2%) has no drainage system, 70(38.9%) has close drainage system. The building coverage of residential houses in the study area; 60(33.3%) has their building falls under 51-75% for over built, 48(26.7%) has their building falls under 76-100% for overbuilt. For the factors influencing the percentage of area built upon, 57(31.7%) has greed and no money to acquire a large plot of land, 47(26.0%) has no land space to built their desirable house. Then, non adherence to provision of adequate ventilation and lighting in the residential houses in the study area affects the dwellers’ health and such factors can promote communicable diseases. In conclusion, it was observed that the compliance rate was not encouraging because the planning regulations recorded very low compliance as include set–back from property boundaries; inadequate free air space; lost of aesthetic values, and inadequate ventilation and lighting. Therefore, government should embark on enforcement of land use plan, and strategic plans for various towns and villages to accommodate its utilities and facilities.

The Future

Urban open spaces (e.g. urban parks) play a pivotal role in improving the quality of life of city dwellers through accommodating various physical and social activities, while further creating social coherence for sustainable development. Due to the shortage of open green spaces in the city, caused by rapid urbanization in developing countries, some big, long-standing urban public spaces such as district parks have been retained, and improved to serve as the main public space for local people. However, such spaces commonly provide outdated, low quality facilities that discourage people from using the park. To satisfy users’ needs, local governments have launched campaigns to improve parks based on the ideas of domestic or foreign designers. The purpose of this research is to explore different behaviors of residents in an open space in Da Nang (Vietnam) which can support the future development and improvement of local open space in accordance with environmental behavior theory. User behaviors were identified and categorized based on their activities in the open space, collected using the place-centered behavior mapping method. Results of the statistical analysis revealed that this open space could be divided into three types, each of which had four dimensions: public facilities setting; openness; accessibility; and recreational facilities. The findings showed some aspects that need to be considered during the development process of open space as follows: 1) increasing the quantity and quality of public amenities; 2) separating accessible space and/or buffer space from already used space inside the park, particularly in the entrance zone; 3) providing space adjacent to the lake; and 4) removing obstacles (e.g. walls around the park) to give a clearer view from inside the park to the streets outside and vice versa. Also, the calculation model of evidence-based designs provides input data for re-planning or creating public space/parks to help designers, planners and authorities improve or design better open spaces in the future.

Rainwater harvesting from roof is considered as valuable water resources. Material Flow Analysis (MFA) of water in Mahasarakham University (Khamriang Campus) shows that rainwater harvesting from roof can reduce water supply production by 7% and save more than 200,000 Bt/year for water treatment cost. The sensitivity analysis suggests that by 5% water supply conservation and 20% additional rainwater harvesting, MSU could have enough water resources. The rainwater is suitable to be substituted water for gardening due to the convenience to assemble an above ground storage tank or a pond to store harvested rainwater from roof. The current practice of rainwater is collected and discharged into drainage system and treated in wastewater treatment plant. Utilisation of rainwater harvested could reduce wastewater amount that must be treated by 9%. Rainwater harvesting and reuse should be promoted in campus in order to encourage sustainable living and water conservation policy.

One of the innumerable ways to systemise contemporary European urban projects is to analyse the urban form originates from the master-plan concept. The duality of closed and open urban situations is an excellent conceptual tool for classification. This classification helps us to recognise, understand and represent the diversity of the city, as it is present on each level of a settlement and architecture. In the case of “Solid-oriented” projects construction and emplacement of buildings are the main goals. The principle of “Solid-oriented” projects are based on two very different, still existing traditions One is the classical European closed block structure, while the other one is the Modernist open urban system. Today we can identify two new approaches combining those two traditions in different ways. Urban transparency preserves streets, the effect of enclosure, and the dominance of buildings. At the same time density is coupled with spaciousness, blocks are fractured and the environment becomes more complex even within one block. The in-between method, based on the idea of structuralism, attempts to balance the importance of mass and space and creates permeable blocks in a new open urban structure. Besides creating urban volumes or buildings in the city, there is a new type of challenge in contemporary urban design. Since the 1990's attention has shifted to cityscape, i.e. to re-interpreting and reforming open spaces. The international literature calls this un-volumetric architecture. The duality of openness and closedness also appears here. While openness seems to dominate urban situations in contemporary cities, buildings are predominantly used in a closed manner.

The Relationship

PurposeThis study examines the relationship between quality and quantity of open space in residential areas and the sense of community of Chinese older adults in Hong Kong.Design/methodology/approachA survey was conducted with 257 adults aged 55 and over in Kwun Tong, Hong Kong. The quality of open space was assessed from four dimensions: social and recreational facilities, entrance, location and environment. Geographic information system (GIS) was used to evaluate the quantity of open space in terms of size and amount.FindingsThe result shows that the environment has a strong influence on the sense of community, while the quantity of open space does not. The results provide urban planners with evidence for open space planning in the future. Urban planners should consider building more people-oriented environment; such as green areas instead of merely increasing the size, amount and facilities of open space. The Hong Kong Government also needs to review the current standardised planning guideline in order to maximise the social connection of older adults.Originality/valueThis cross-sectional study tried to understand the relationship between the quality and quantity of open spaces and sense of community in Chinese older adults in Hong Kong. It is one of the few studies to simultaneously examine both the quality and quantity of open spaces when studying its relationship with sense of community.

In the paper were made the verification of the operation of a rainwater drainage system in the residential communities of Gaj and Tarnogaj in Wrocław, carried out in the hydrodynamic model using SWMM software. There were used two criterial precipitation: Euler’s model (with a frequency of C = 3 years) and the actual precipitation (C = 5 years). The criteria of overloading the system was the specific flood volume (SFV). For both cases of precipitation load of catchment, the simulated calculations showed the occurrence of outflows from the channels. Due to the value of SFV indicator (respectively: 19 m3/ha and 42,9 m3/ha), it was found that the tested system needs modernization, therefor acceptable instantaneous water level above the maximum water impoundment were more often than 1 per 3 years, which leads to overflows from channels for residential areas more often than allowed once every 20 years.
