The Cypress Street area of Tampa consists of one residential street, two mixed-use streets, and one commercial street in a low-lying area of the city close to the central business district and Tampa Bay. Our Oldcastle Infrastructure business worked to develop a drainage solution for the area that was effective, efficient, and economical while increasing its safety and sustainability.

The challenge

Frequent and excessive stormwater runoff was overwhelming the heart of downtown Tampa due to its antiquated storm drainage system. As a result, the city was having ongoing business and residential flooding, coupled with significant traffic delays and disruptions.

The solution

To address these issues, the Oldcastle Infrastructure team completed an extensive range of works to augment the existing drainage system on Cypress Street. This included installing nearly 7,300 linear feet of Box Culverts, 18 Storm Manholes, three Nutrient Separating Baffle Boxes® (NSBB) Units and 73 Curb Inlets with integrated Flogard® filters.

The Box Culverts and Manholes significantly expanded the drainage capacity, replacing an outdated low-capacity patchwork drainage system with a contiguous, integrated high-capacity system. The NSBB units have a patented screen system designed to capture and store trash and debris in a dry state, while the Flogard® Curb Inlets provided the necessary filtration to remove contaminates from the stormwater runoff before they even enter the drainage system.

Oldcastle Infrastructure used a novel systems approach to design the right combination of filtration and drainage capacity for this project. These innovative solutions have significantly reduced the amount of polluted stormwater runoff to otherwise clean water sources, greatly improving Tampa’s overall water quality.

This project showcased Oldcastle Infrastructure’s ability to provide comprehensive, turnkey support and solutions that modernise communities and transform the lives of their residents. As a full solutions provider, Oldcastle Infrastructure’s systems offered an increased level of drainage in a residential area that is historically prone to flooding. By eliminating business and residential flooding due to previous poor stormwater drainage, Tampa traffic safety has also vastly improved.
