The District owns just one small property in Port Costa that is used by the Port Costa Sanitary Department. This property
is on the shoreline at the end of Canyon Lake Drive, where the wastewater
treatment plant is located. An underground wastewater holding tank
('septic tank') nearby has been leased in perpetuity from the Union Pacific
Railroad at no cost.
The Port Costa Sanitary Commission enjoys the use of rent-free space at
the Port Costa School to hold its monthly public meetings, which are typically
held at 7:00 PM on the first Wednesday of each month.
