Title:

Green Infrastructure and Low-Impact Development Design for Roadway Environs Subject to Rainfall-Runoff Loadings

Accession Number:

Record Type:

Abstract:

Impervious surfaces alter hydrology while impacting the chemical balances of water resources. While historical issues of flooding are still a concern, chemistry, loads and aesthetics are companion concerns. Recently, Total Maximum Daily Loads have been promulgated. Additionally, Florida has promulgated no net load increases for runoff and pollutants and is facing imminent numeric criteria for nutrients. With recent trends towards low impact development (LID) and green infrastructure, hydrologic restoration, reuse and source control are part of urban retrofit design practice. This project demonstrates that hydrologic and pollutant load can be managed with roadway re-design providing no net increase for long-term loadings. Specifically, the proposed design retrofits an existing surface parking facility with a series of design elements. A biofiltration area reactor (BAR) is clay-lined for water table and denitrification management. A linear infiltration reactor (LIR) of cementitious permeable pavement provides infiltration/evaporation, filtration and adsorption. Pavement sweeping provides source control. Continuous simulations with climate and site data indicate that re-design can achieve a no load increase. Cost estimates demonstrate that re-design is comparable to conventional construction costs while incorporating Florida-friendly landscape. Additionally, design options yield a lower cost per nutrient load treated compared to conventional Best Management Practices (BMPs).
