Will there be development restrictions above the tunnel?

ALCOSAN does not anticipate any building restrictions above the tunnel due to its depth. Subterranean easements will be needed along the tunnel alignment, but this will have no impact on surface activities and the landowners’ ability to sell or develop their land. The only development restrictions will be above the shafts/regulators as ALCOSAN will need continued access to these structures. If repairs are needed on the tunnel, ALCOSAN would access the tunnel through these locations.
