Assessment of Critical Slope in Selangor, N. Sembilan & Melaka
Based on the 2017 study "Penghasilan Peta Bahaya dan Risiko Cerun di Kawasan Gombak-Selayang-Rawang-Batang Kali, Selangor dan Cheras Selatan-Kajang-Bangi, Selangor," 20 locations were identified as critical slopes. Geotechnica Sdn Bhd was engaged by JMG Selangor & Negeri Sembilan and GoGEO to assess and update the current hazard and risk rating for these sites.

Project Overview
Scope, conditions & requirements
Project Scope
Update the hazard and risk rating of 20 previously identified critical slope locations across Selangor, Negeri Sembilan and Melaka.
Site Conditions
Sites span 12 local authorities — 6 in Selangor (MPKJ, MPAJ, MP Selayang, MD Hulu Langat, MP Sepang, DBKL) and 6 in Negeri Sembilan (MP Seremban, MD Jelebu, MP Port Dickson, MD Tampin, MP Alor Gajah, MB Melaka).
Investigation Requirements
Reassessment was needed to align current site conditions with the Slope Information Management System (SIMS), updating ratings from the original 2017 study.
Our Approach
How the rating was updated
Desk Review
Reviewed the 2017 "Penghasilan Peta Bahaya dan Risiko Cerun" study identifying the original 20 critical slope locations.
Field Verification
Site assessment across slopes spanning the 12 participating local authorities in Selangor and Negeri Sembilan.
SIMS Rating Update
Current hazard and risk ratings updated in line with the Slope Information Management System.
Key Findings
What the assessment showed
Finding 1
Hazard and risk ratings were reassessed across all 20 previously identified critical slope locations.
Finding 2
Updated ratings reflected current site conditions across the 12 participating local authorities in Selangor and Negeri Sembilan.
Project Outcomes
How the findings are used
Updated hazard and risk ratings were delivered to JMG Selangor & Negeri Sembilan, supporting each local authority's slope management and monitoring priorities across the three states.
