Home

The Mt. View Sanitary District is aware of the recent occurrence of strong odors in the Vine Hill neighborhood that may smell a little like rotten eggs. These odors are temporary and we apologize for this inconvenience. These odors, originating in McNabney Marsh, are the result of decaying plant material and occur when the water level in McNabney Marsh gets low enough to expose large areas of mud.

The flow of water in and out of McNabney Marsh is controlled by a tide gate that regulates flow of seawater up Peyton Slough into McNabney. Currently, due to a construction project in the Rhodia Marsh (located on the north side of Waterfront Road), the tide gate is closed, preventing flows into McNabney. Unfortunately, Mt. View Sanitary District was not provided sufficient notice of the closing of the tide gate to be able to take actions that might have prevented exposing the large areas of mud from which the odor originates. The construction project requiring the tide gate to be closed is anticipated to be complete by October 3.

In the meantime, Mt. View Sanitary District and the tide gate operator are working to try to raise the water level in McNabney March to cover the exposed muds and limit the odor problem. This requires careful manipulation of the tide gate located on Peyton Slough as well as channel gates located in McNabney Marsh. The opening and closing of these gates must coincide with the tidal cycle in Carquinez Strait to capture as much water in McNabney Marsh as possible without overtopping Peyton Slough and inundating the construction site. Please be patient as it may require a few days of high tides to be able to raise the water level in McNabney Marsh enough to cover the exposed muds.

We are working hard to eliminate these odors for you as soon as possible and we appreciate your patience and understanding in the meantime. Again, we apologize for this temporary inconvenience.

If you have questions or concerns, please contact Patti Ransdell at (510) 285-6744 or p.ransdell@circlepoint.com.
