This is a community organized and conducted project that seeks to remove the materials that have settled in the channel over time from its opening at the Potomac River all the way to its opening with the main body of Cubitt Creek. The material is sand on top with soft clay underneath and is choking off the creek habitat by significantly impeding the tidal water exchanges.
The channel will be dredged using a hand held 3 inch hose utilizing a suction pump to transport the sand by 3 or 4 inch hose to reinforce the existing breakwaters of adjacent beach of White Sand Harbour. The channel will be 20 feet wide and 1500 feel long with a bottom depth MLW of 4 feet with an additional 1/2 foot undercut. It will follow the current natural channel and will not disturb any sea grasses or wetlands. Unusable material will be pumped to an adjacent farm where it will be dewatered, spread out, and plowed into the farmland soil or otherwise buried.
The primary purpose of this project is the restoration of a healthy tidal exchange between Cubitt Creek and the Potomac River to decrease the high bacterial concentrations which have been measured to be the worst of all creeks in the area. A secondary purpose is to avert any return to the creek's 2004-2007 designation by VA DEQ as Impaired for Recreation and Condemed for Shellfish Harvesting based upon its TDML fecal coliform violation rate. An ancillary result should include the protection of the White Sand Harbour Beach and restoration of a navigable channel for recreational boating with small vessels.
The Cubitt Creek Association, LLC is also applying for a long term maintenance dredging permit once the channel depth has been established. The materials removed during approved future maintenance will be distributed in the same fashion as the original dredging. Depending on the success of this project and sufficient funding, there may be a future permit requesting permission to construct jetties into the Potomac River.
There is no new development or expansion of existing land use proposed, no alteration of surface waters proposed, no surface water withdrawals involved, no public service water supply withdrawals, and no in-stream flow alterations. There are also no utility crossings affected.
