Stormwater Management is often an area of engineering that must be designed for various phases of construction. During construction, we often must look at stormwater management as it relates to erosion and sediment. This area is addressed by Storm Water Pollution Prevention Plans (SWPPP) which are large documents that explain how stormwater is to be handled during construction in order to protect downstream receiving waters. However, after construction has completed it is important that sites are designed to satisfy post-development water quality device requirements. When designing post construction devices, we first take into consideration soil constraints relating to percolation rates, liquefaction and groundwater pollution. After those considerations are taken, we propose infiltration systems, capture/reuse devices or biofiltration devices.
