This course looks at the evolution of stormwater management and how it has shaped site development decision-making. The course discusses the emerging concept of veneer hydrology, a shallow horizontal waterflow management system that uses evapotranspiration instead of infiltration. Veneer hydrology entails placing thin layers of soil and vegetation in areas of the urban environment that don’t lend themselves to landscaping such as over utilities, buried structures, and subways. Key design parameters are outlined to bridge challenging landscapes with unstable soils and limited depth settings.

Learning Objectives

  • Examine the hydrological variability and distinctive conditions that are common to urban sites and be able to describe a new urban hydrological system
  • Provide a perspective on the evolution of stormwater management philosophy and how it shapes site-development decision-making and be able to describe the limitations of infiltration-based strategies
  • Consider an alternative complimentary, horizontal model: how it works, its benefits, and where it applies
  • Describe how veneer landscapes may be used in conjunction with other stormwater management practices and discuss larger community benefits when these practices are applied widely
