Construction of a site of any magnitude is a process that requires a certain amount of staging. When dealing with a mega-site, staging is an even more delicate process that requires some temporary site infrastructure.
In today's episode, Mike touches on grading, water drainage, and storm water management ponds or SWM (swim) ponds. These are temporary SWM ponds. They act in conjunction with other erosion and Sediment Control features like silt fences and straw bales to lower the velocity and suspend solids from rain events. These temporary SWM ponds are located around the site at the low points in drainage areas. Once the new road network is built, they will be replaced with larger permanent ponds and storm sewers in 2025.
The permanent SWM pond locations are shown in blue on the site plan.
