Counties will have to submit projects above Sh500 million through the Public Investment Management team at the Treasury.
Most county projects have been delayed, stalled and failed due to inadequate stakeholder engagement, misalignment to national priorities.
The National Treasury will begin vetting flagship projects selected by county governments to curb wastage through stalled and incomplete works.
In a circular it said it has included county governments among ministries departments and agencies which will have to obtain clearance before undertaking Vision 2030 flagship projects.
