Key Credit Considerations

The ratings actions reflect the following key credit considerations:

Credit Positives

• Sizable and diversifying economy, centered around the Nation’s fourth largest city, which has benefited from above average property tax base growth.
• Historically stable property tax collections through a variety of economic cycles, which KBRA believes demonstrates the area’s economic and tax base resilience.
• The County electorate in November 2024 approved a permanent increase in the O&M property tax levy for the Harris County Flood Control District that will provide an additional $100 million each year toward activities mitigating future flood risks and protecting the property tax base.
• Ample headroom between levied District Tax rate and the statutory maximum rate.

Credit Challenges

• Susceptibility to significant storm activity given its domicile on Texas’s Gulf Coast, as evidenced by Hurricane Harvey and other tropical systems, which have necessitated borrowing to bolster infrastructure resiliency.

Rating Sensitivities

For Upgrade

• Not applicable at AAA rating level.

For Downgrade

• A sizable and sustained economic contraction for the County / Houston-The Woodlands-Sugarland MSA, resulting in a material reduction in the tax base.
