The South Detention Vault is the first of three regional stormwater facilities to be constructed in Overlake Village. It will detain stormwater that has been treated locally within public rights-of-way and private development areas.
When completed the vault will have a total volume of 20 acre feet (about 6.6 million gallons). Park facilities will be constructed on top of the stormwater vault in the future. In the meantime, the property owner will use the area over the vault for parking.
Utility relocations to accommodate the new vault were completed in 2013. The vault is now under construction and will be operational by the end of 2014 with site restoration completed in 2015.
