HR Green has been selected by the St. George Place Redevelopment Authority (TIRZ 1) and Harris County Precinct 4 to advance the Chimney Rock Road and Anderson Park Drainage Improvements project, supported by $29.25 million in Community Development Block Grant–Mitigation (CDBG-MIT) funding administered by the Texas General Land Office. CDBG-MIT resources are intended to help communities reduce long-term disaster risk by strengthening resilience and lessening the impacts of future storms.
The project will deliver critical flood mitigation in and around the TIRZ 1 area by rebuilding Chimney Rock Road from Westheimer Road south to Interstate 69. Large reinforced concrete box storm sewers beneath the roadway will substantially increase the area’s ability to move stormwater efficiently to Buffalo Bayou, reducing the prolonged pooling and damaging overland sheet flow that can lead to structural flooding in surrounding neighborhoods. Because the new drainage system requires significant excavation across the corridor, the roadway will be fully reconstructed as part of the work, resulting in a safer, more resilient transportation route for residents and visitors.
Anderson Park will also be reconstructed to work in tandem with the drainage upgrades, adding stormwater detention through strategically graded, above-ground storage areas within the park. Natural detention and water-quality features such as bioswales will help capture and treat runoff, while the overall park redesign will support both stormwater management and everyday community use.
Beyond drainage performance, the park enhancements will help turn an underutilized space into a true destination, with new infrastructure (water, sewer, drainage, electrical power), improved parking and pedestrian paving, and new amenities such as a playground, multi-purpose lawn, trails, landscaped green space, sports and recreation features, and art elements. Together, these upgrades are designed to create a more inviting, active community hub while also playing a meaningful role in reducing flood risk.
This win reflects a long-standing partnership—HR Green has been working alongside TIRZ 1 and Harris County Precinct 4 for several years to support their vision for resilient infrastructure and community-focused improvements. With this project serving as an early step in a broader, phased regional flood mitigation strategy, the corridor and park improvements will deliver near-term protection for nearby neighborhoods while laying the groundwork for lasting, measurable resilience.
