What's That Pounding Noise?

A few residents have expressed their concern to the City over the seemingly incessant pounding noise that's been taking place over the last week or so.  Upon further investigation, it's been determined that the noise is a result of pile-driving near Candlestick Park (Harney Way) where SFPUC is constructing a new auxiliary sewer tunnel between the Sunnydale drainage basin (Visitacion Valley District) and the Sunnydale Transport/Storage Facility located just southwest of Candlestick Park. The new sewer tunnel will increase the capacity of the sewer collection system on Kelloch Avenue, Velasco Avenue, Talbert Street and Sunnydale Avenue during heavy rain periods.

The pile-driving at Harney Way was completed yesterday, but contractors of SFPUC will be moving to a new site (Sunnydale & Bayshore) early next week to begin pile-driving that will last for another week or so.  However, the level of noise that travels to Brisbane from this work should be largely reduced, as the area they will be working in will be only 25' x 25' (as opposed to the several hundred at Candlestick).  In addition, this location is much more shielded with structures in-between that will help absorb the noise.
