The area west of the dip is on higher ground and stable. The area after the dip on Pitkin is in the Spring Creek flood plain. Any tunnel is below the water table. It's why the streets were raised there.Water seepage,does anyone besides me realize that you FIX a leak from where its coming from?the floor of the tunnel is ballast, water would leak under it even if it was backfilled with dirt.wouldn`t it seep up into the street at a certain point,causing a collapse. A tunnel built and abandoned much past Elderts Lane would indeed risk a street collapse. The fact that that street has never had any such problems is another indicator that the tunnel could not have made it even up to the school. What was left of it beyond the walls has most likely been integrated into the sewer and drainage system. |
