Overlake Village South Detention Vault Project
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.
Check Redmond’s Traffic Alerts (link) page for construction impacts to local streets.
Project Update: July 2014
Phase 2 - Overlake Village South Detention Vault Construction is Underway
NE 20th Street will be open during the day with lane restrictions. Traffic levels on other arterial roads in the vicinity of the project likely will increase during the construction periods. Work will occur primarily during the day time with the possibility of some night work.
The South Detention Vault will be constructed in three stages:
March - November
(Construction begins on the vault's south cell)
November - January 2015
Stage 3 (final stage)
January 2015 - June 2015
Summer 2015: Project scheduled for completion
