The follow-up audit found the department still has not fully implemented recommendations to:
❌ Create guidance for handling sensitive data
❌ Establish quality assurance processes
⚠️ Fully manage file access permissions. #CitySheltersFollowup

[Auditor Tim O'Brien @DenverAuditor]

The follow-up found Denver still lacks effective oversight of shelter provider spending.
❌ No full tracking of shelter-related expenses
❌ Weak invoicing controls
❌ Staffing shortages
❌ Limited accountability for taxpayer dollars. #CitySheltersFollowup

[Auditor Tim O'Brien @DenverAuditor]

Auditors found incomplete action on:
❌ Security assessments
⚠️ Grievance procedures
⚠️ Nondiscrimination monitoring

These gaps may leave shelter guests without clear protections or reporting processes. #CitySheltersFollowup

[Auditor Tim O'Brien @DenverAuditor]

Our follow-up found Denver’s Department of Housing Stability still has gaps in shelter safety and nondiscrimination oversight.

[Auditor Tim O'Brien @DenverAuditor]

This concludes the Fleet Management follow-up report. You can find the audit report at https://t.co/wxbHNqW2bR

[Auditor Tim O'Brien @DenverAuditor]

Our #FleetManagementFollowup found former city employees had not been removed from the city’s authorized fuel user list.

DOTI staff says they addressed this after the audit team had completed its follow up review period.

[Auditor Tim O'Brien @DenverAuditor]

DOTI staff claim by today they have since implemented Recommendation 3.2 -Remove unauthorized users from the driver database.
#FleetManagementFollowup.

[Auditor Tim O'Brien @DenverAuditor]

Transportation & Infrastructure is still covering fuel and maintenance costs for other agencies due to outdated fleet funding regulations. #FleetManagementFollowup.

[Auditor Tim O'Brien @DenverAuditor]

Key risks still exist:
Fleet funding structure outdated
Staffing and vehicle plans are incomplete
Fuel monitoring partially implemented
Unauthorized users still in the driver database
Physical security assessments are unfinished
