Stormwater Management

Why is Stormwater a Concern?

Why is Stormwater a Concern?

Eutrophication  Impacts due to urbanization:  I m pact to aquatic habitat: Degradation of habitat structure, loss of pool-riffle structure, reduction in base flow, increased stream temperature, and decline in abundance and biodiversity. Fish kill at Lake Granbury.

Green Stormwater Infrastructure  Rain garden- bioretention areas  Porous pavements  Green roofs  Rainwater harvesting

What is a Rain Garden (Bioretention)? A rain garden is a beautiful landscape feature consisting of a planted shallow depression that collects rainwater runoff from roofs, parking lots and other impervious surfaces.

Volume Reduction Average Reduction: 49%

Load Reduction: Sediments Average Reduction 90%

Load Reduction: E. coli Average Reduction 64%

What is Porous Pavement?  Porous pavement is a permeable pavement surface with a gravel reservoir underneath.  it temporarily stores surface runoff before infiltrating it into the subsoil  provides water quality treatment  often appears as traditional asphalt or concrete but is without "fine" materials  could also allow for grass growth

Types of Permeable Pavement Porous concrete Paver blocks Porous asphalt Turf Paver Expanded shale mix

Impact of Climate Change on Dallas Stormwater Network

Conclusions  It is necessary to approach water the water cycle as whole in management strategies at city, watershed or country scale  Such approach requires field data, modeling and research-based answers to be implemented  Research-based strategies developed need to include stakeholder feedback to succeed  Findings need to be integrated in academic curriculums and spread through extension programming
