Mombasa Governor Abdullswamad Nassir has banned the on-site mixing of ballast, sand, and cement at construction sites, effective September 14, to combat worsening flood conditions.

• Developers with existing approvals have a 48-hour window to use or store materials.
• The ban is a measure by Mombasa County to prevent construction debris from obstructing drainage systems during heavy rainfall.
• The county plans to deploy 3,000 young people to clear drains and waterways as part of broader flood prevention efforts.
