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 nearly complete and site restoration will be completed in 2015.

Overlake Village South Detention Vault Construction
The first stage of construction will be completed by November 19, 2014. Major construction will be suspended during the holiday season to accommodate local businesses.
During this first stage, the south cell of the vault and flow splitter were completed. The south cell will be operational by early December to begin storing stormwater runoff.
The final stage of construction will begin on January 6, 2015. The vault construction continues to be on schedule for completion in summer 2015.
The South Detention Vault will be constructed in three stages:
Stage 1 (Non-Holiday Season)
March - November
(Construction begins on the vault's south cell)
Stage 2 (Holiday Season)
November - January 2015
Stage 3 (Non-Holiday Season & Final Stage)
