Round Rock Dam Project Nears Completion to Mitigate Flood Risk for 1,000+ Homes

A significant dam project along Lake Creek in Round Rock, Texas, is nearing completion to address persistent flooding issues affecting over 1,000 homes in flood-prone neighborhoods. The dam, nearly a mile long and four stories tall, aims to contain runoff during heavy rains and reduce flood risks along more than five miles of Lake Creek.

This infrastructure initiative is part of an $85 million bond program approved by voters in 2020, funded and led by the Upper Brushy Creek Water Control and Improvement District (WCID) with support from the city of Round Rock. The city allocated $2 million toward the dam's $35 million construction and design expenses. Construction is expected to be substantially complete by the end of the current year, with final completion slated for early 2026. Post-completion, the Federal Emergency Management Agency (FEMA) will evaluate changes to the floodplain, which may influence homeowners' flood insurance rates and potentially provide financial relief to affected residents. Flood insurance premiums have been a significant expense for the community, contributing to thousands of dollars in combined insurance costs for homeowners. This project reflects a coordinated municipal and regional effort to enhance flood risk management and protect local homeowners, with implications for future insurance and compliance landscapes in flood mitigation policy.
