THE PROPOSED PAN ISLAND LINK 1 HIGHWAY PROJECT, PENANG CHAPTER 6 EXISTING ENVIRONMENT 6.0 INTRODUCTION This section describes the condition of the existing environment in the study area which includes the physical, biological and socio-economic environment. The description of the existing environment is based on field surveys and review of existing literature related to the study area sourced from published reports. 6.1 PHYSICAL ENVIRONMENT 6.1.1 Topography The topography of the study area is illustrated in Figure 6.1.1. The highest contour in the project site is 440 m and the lowest is 1 m above the Mean Sea Level (MSL). The height of the proposed new highway alignment will gradually increase as it approaches the island center. Figure 6.1.2 (a) and (b) shows the elevation. The description of the road alignment is divided into 3 sections (Table 6.1.1). Section 1 starts from the low area at Gurney Drive (1-2 m above MSL) and gradually increase as it traverses towards Youth Park (50 m above MSL). Section 2 which starts from Youth Park to Sg. Ara traverses over the hilly areas, valleys, and foothills. There are four (4) hilly areas where tunnels will be constructed. Tunnel 1 and Tunnel 3 will pass through highland areas where the maximum elevation is 290m and 440m above the MSL respectively. There are two (2) viaducts sections at Air Itam and Paya Terubong. The Air Itam area (between Tunnel 1 and Tunnel 2) has elevations ranging from 60-137m above the MSL. For Paya Terubong area, the elevation is about 43-78m. The embankments section near Relau area is at an elevation of 83-139m. The elevation in Section 3 is about 72m after the exit of Tunnel 4 and gradually reduces as the alignment goes along the river reserve (Sg. Ara and Sg. Kluang) to the Tun Dr. LCE Expressway (1 m above the MSL). 6 - 1 THE PROPOSED PAN ISLAND LINK 1 HIGHWAY PROJECT, PENANG Table 6.1.1.

Based on slope analysis (Table 6.1.2), 61.7% of the area is classified as Class 1 which is predominant in Section 1 and Section 3. For Section 2, there is a mix of Class category since the area consists of a mixed elevation hilly area. Most of the slopes fall under Class 2 (20.9%) and Class 3 (14.3%). No surface construction works will be carried out on slopes of more than 35° (Class 4). Table 6.1.2.

The proposed Highway alignment is designed to avoid sensitive areas as much as possible (with respect to potential social and environmental issues); it traverses mostly through hilly forest areas, river reserves and lastly on Highway medians. The highly densely developed areas can be divided into 3 sections viz. Gurney to Gottlieb area, Air Itam to Relau Area and Sg. Ara to Bayan Lepas area. Section 1 is dominated by mixed developments along Jalan Bagan Jermal to Jalan Gottlieb. In Section 2, most of the land use is forest at 78.5%. For Section 3, the land use comprise rivers, and residential and industrial premises. Table 6.1.3.

The granite rock occupies the high terrain area in the centre of the island and sealine. Granitic rocks are classified into two major plutons i.e the North Penang pluton and South Penang pluton (Ong Wee Seck, 1993), as published by the Minerals and Geoscience Department of Malaysia (JMG, Formerly known as the Geological Department of Malaysia). Tan Bong Kong (1994) divided granitic rocks in Penang into Type 1-Sungai Ara Type and Type II- Bukit Bendera Type. However, for the purpose of this report, the classification by JMG is used. This classification is based on differences in age, mineralogy and texture of the granites. The North Penang pluton is of Triassic age, does not contain primary muscovite and is coarse grain. The South Penang pluton is of late Carboniferus to early Permian age, contains primary muscovite and medium grain matrix size.
