The California Main Lodge has approximately 14 acres of paved parking partially in SEZ. The existing storm drain system treated runoff with 4,000 to 20,000 gallon sedimentation vaults installed in 1989 and restoration of SEZ in the Bijou Creek watershed. Construction of Phase I has recently been completed (October 2006). Phase II construction is scheduled for Fall 2007. Features of the ongoing BMP retrofit project include:
- Rerouting the collection system to separate parking lot runoff and upgradient clear water flows.
- Parking lot runoff that receives pre-treatment in existing sediment vaults will be routed to a series of new treatment units using cartridge technology for nutrient removal.
- Enhancement of the snow storage areas to reduce sediment transport and improve snowmelt water quality.
- Installation of automated sampling for the completed system.
