Sunnydale Auxiliary Sewer Tunnel Project (WW-487)

Phase I - $53 Million
Work includes construction of a sewer tunnel from Sunnydale Avenue and Talbert Street to send wastewater eastward to the Sunnydale Transport/Storage structure, located adjacent to the San Francisco Bay near Harney Way and Alana Way.

Micro-tunnel Extension Phase 1a

The construction of new sewer tunnels from Harney Way to Talbert Street (Phase 1) will be completed in January 2012. The SFPUC intends to partially activate the new sewer tunnel starting January 2012 to provide localized storm flooding protection to the Visitacion Valley community. Starting in February 2012, the contractor will be initiating an extension of the micro-tunnel (Phase 1a) from the existing Talbert shaft to the Rutland shaft, and then from the Rutland shaft to the Schwerin shaft. This work is identical to the completed installation of the sewer tunnel on Sunnydale Avenue from Bayshore Boulevard to Talbert Street.

Phase II - $11 Million
Work includes construction of sewer pipelines along Visitacion Avenue between Talbert and Rutland streets.

Construction Schedule:

Phase I - Fall of 2010 to Early 2012
Phase II - Summer of 2011 to Spring of 2012

During construction hours, parking will be temporarily prohibited.  “NO PARKING" signs will be posted in areas where there are construction activities.  Access to garages of residences in the construction area will be maintained at all times, though residents may experience some delays/ inconveniences.  Muni Bus Line No. 9 will be temporarily rerouted in the Talbert/Sunnydale vicinity.

Noise - Residents and businesses can expect noise from the use of construction equipment.

Dust -  Standard construction dust control measures to be implemented (i.e. – misting active construction areas, covering all trucks hauling soils/debris, routine wet sweepers).
