Careful management and distribution of runoff aids sustainable urban development. Conventional runoff management generally employs grey infrastructure and sewers to convey the stormwater quickly to safe places. Such practices often increase peak runoff, reduce infiltration and percolation to groundwater storage, and degrade the environment. As a low impact development (LID) alternative, Green Infrastructure (GI) can provide better environmental, social, and economic consequences. After validating an existing calibrated Hydrologic Simulation Program-FORTRAN (HSPF), we predict hydrologic consequences of implementing GI practices in Salt Lake County, Utah. For this intermountain valley urban watershed, we compare predicted groundwater recharge, runoff and stream flow for current and alternative GI land uses. Results will aid decision makers in policy deliberations.

Analysis of Green Infrastructure Practices on Urban Runoff and Groundwater Storage Enhancement using HSPF

The International Low Impact Development Conference highlights interdisciplinary practice, research, and implementation of Low Impact Development (LID), Green Infrastructure (GI), Sustainable Urban Drainage Systems (SUDS) and Water Sensitive Urban Designs (WSUD). The focus of this conference was on using our past and present understanding of LID to tune management programs, design practice, and operation and maintenance into the future.
