SEIA for Conversion of Light Industry to Medium Industry, Kulai, Johor 5.0 EXISTING ENVIRONMENT 5.1 Introduction This section describes the physical, chemical, biological and social condition of the existing environment in the vicinity of the project site and its surrounding areas. Official published secondary literatures were referred in addition to fulfil the gaps of the primary information and baseline data collected during site visit and field investigation. 5.2 Topography, Soil and Geology The project site is currently a vacant industrial land. Site clearance of site has been previously completed for light industrial purposes. Geologically, the project site is underlain by intrusive rocks ( Figure 5.2.1 ). According to Generalized Soil Map of Peninsular Malaysia ( Figure 5.2.2) , the soil of the Project Site consists of Red Yellow Podzolic soil with Reddish-Brown Lateritic soils.

Skudai before entering Straits of Johor. Drainage pattern adjacent to the project site is shown in Figure 5.3.1. There is a water intake point at Sg. Skudai (N 1 o33’30”, E 103 o39’40”), about 10km downstream of the project site. Sg. Skudai can be considered to be a partial urban river, which receives a myriad of point and non-point source pollution from various contributors including kampung areas in both Senai and Skudai. Industrial effluent also enters Sg. Skudai directly, such as from the Senai Industrial Area.
