Penang Hill Corporation (PHC), as the custodian of Penang Hill, takes responsibility for conserving and preserving our natural ecosystem with minimal environmental impact. Throughout the years, bad weather, heavy downpours, and intermittent rains have caused inevitable landslides at various spots on Penang Hill. PHC ensures regular tree trimming to protect thousands of daily visitors from fallen branches. The hill maintenance team promptly clears blockages for the safety of residents, visitors, and hikers. During adverse weather conditions, hikers are advised to avoid hiking and take precautionary measures to ensure their safety.

Since 2017, landslides have been identified, recorded, and stabilized in and around Penang Hill. PHC has taken immediate steps to carry out slope mitigation works, periodic monitoring, and evaluating the stability of soil slopes. Collapsed slopes have been repaired and reinforced through permanent slope strengthening works using soil nailing, retaining walls, and the upgrading of the drainage system. Necessary slope maintenance is carried out regularly to ensure the slopes are stable.

From 2018 until 2021, more than 20 slope stabilization projects covering over 100 landslide locations have been repaired around Penang Hill. In 2022, slope repair work included continuously upgrading the slope maintenance and monitoring system to be more systematic. Regular slope maintenance is essential for all hill slopes classified with topographic survey plans to define local features such as slips and man-made slopes or structures. Slope data is recorded in the Slope Maintenance Manual Form issued by the Jabatan Kerja Raya (JKR) “Slope Maintenance Guidelines in Malaysia, Slope Engineering Branch, JKR Malaysia, August 2006.”

One of the locations, the surrounding area of Edgecliff bungalow has been stabilized and reinforced using a soil nailing system, and the drainage system has been upgraded to enhance the safety of the vicinity around the building. This initiative aims to preserve the existing hillside area, ensuring its safety for visitors to Penang Hill. The proposed development for the Edgecliff Bungalow to be converted into a visitor gallery, was officially launched on 8 July 2022 as the Penang Hill Gallery@Edgecliff. The Edgecliff Bungalow is a state-owned category II heritage bungalow which now houses exhibits and artifacts on the biodiversity, heritage, cultural and funicular of Penang Hill.
