Cinco Ranch Custom Stormwater Management

Cinco Ranch Custom Stormwater Management

A new residential development in Richmond, Texas benefited from a custom stormwater management solution that expertly combined storage and treatment to mitigate flooding and manage water quality.

 

The challenge

During its design phase the engineers working on the Cinco Ranch residential development in Richmond, Texas faced a significant stormwater management challenge.

Nearby buildings and parking lots presented a number of impervious surfaces, meaning that the site would have to incorporate effective flood mitigation measures.

Limited space and a high local cost of land meant that a retention pond would either take over half the area of the parking lot, or be cost-prohibitive. Additionally, the geography of the local area allowed for only shallow construction. A pond could not be the solution. 

 

The solution

The specifying engineer worked with one of Oldcastle Infrastructure’s stormwater management experts to address site constraints, taking into account the impervious nature of the site and shallow outfall. The team decided on underground storage to maximize the use of land. 

Oldcastle Infrastructure worked with the engineer to design a site-specific custom stormwater detention and treatment system, combining the Nutrient Separating Baffle Box® (NSBB®) and StormCapture® technologies. The team used the Online Design Tool to collaborate and develop stormwater management designs quickly and easily. 

The NSBB was used for trash capture and pretreatment upstream of the underground detention, while StormCapture solved site constraints and prevented the need for a large, costly retention pond.

In addition to providing design support, Oldcastle Infrastructure representatives were on site during the installation. By providing  ongoing support to the contractor, installation was completed safely and efficiently.

 

About NSBB

The NSBB removes trash, sediment, Total Suspended Solids (TSS), and nutrients. The triple-chamber design removes high levels of TSS over a wide range of particle sizes. In addition, patented deflectors ensure no sediment scouring occurs during high flows, allowing for on-line installation without the need for separate diversion structures.

 

About StormCapture

The StormCapture system provides tailored, efficient storage that replenishes aquifers, manages stormwater, and ensures compliance with environmental regulations—helping projects like Cinco Ranch contribute to long-term water security and environmental stewardship. 

 

Benefits

Flexible to Design, Easy to Install

Unlike traditional stormwater treatment methods such as sedimentation ponds, the NSBB is smaller, more flexible and easier to install. Its shallow, small footprint is designed for easier and numerous placements

Designed for Easy Maintenance

The NSBB uses a patented screen system to capture and store debris in a dry state to minimize nutrient leaching and allow for efficient maintenance.

Increased Detention Capacity

StormCapture facilitated the addition of detention capacity without compromising the parking lot size, optimizing the use of available space.
