Paper Title
Environmental Impact Assessment of the Developing Urban Area, Makkah, Saudi Arabia

Abstract
This paper presents an environmental impact assessment (EIA) of the urban development of Misfalah area due to its importance for its proximity to the Holy Mosque in Makkah, and its urbanizationproblems. Also, the highlighted areawill be transformed to a multi-use modernized urban site that will improve the urban fabric of Makkah. The EIA covers a definition of the general environmental frameworks and the executive environmental regulations in Saudi Arabia, a description of the current situation in Misfalah, the proposed development plan, the environmental factors surrounding the region, expected environmental impacts during construction and operation, and various alternatives to minimize the negative environmental impacts, and finally the environmental management plan. The assessment of air quality done in 2016 and can be summarized as (average Sulfur Dioxide 15.92 µg/m3, Nitrogen Dioxide 118.28 µg/m3, Carbon Monoxide 1.31 mg/m3 and inhalable dust 29.14 µg/m3), and the noise levels during the daytime (54.5-64.9 dBa) compared with night time (51.2-57.6 dBa).Climatologically, the average hourly temperature was 31.51 ° C, the hourly average of relative humidity reaches 35.86 %, wind speed average reached 5.75 m/s. Topographically, the altitudes in the studied area range between 234-386 m, and the subsurface geology can be described by the Juaranah Complex formed by highly cracked and weathered granodiorites, while the average depthto the groundwater bearing formation ranging from 10 to 30 m. Finally, the study concluded that the developing urban are of Misfalah might cause little impact on the surrounding environment, except some factors related to the inhalable dustand noise during the construction phase. The project has positive socially and economically influenceon building capacity, providing green and open areas, parking and creating new job opportunities. Environmental standard measures haveconsidered and implemented with the establishment of environmental management plan and a monitoring system to track and record any potential gaseous emissionandunusualnoise level.
