Upper Grape Creek Flow Restoration and Offstream Storage Project
MND - Mitigated Negative Declaration
Present Land Use
Land intensive agriculture, biotic resource zone
The purpose of this project is to increase the amount of instream flow during critical dry periods, while providing a reliable water source to meet existing vineyard water needs. This project consists of an off-stream water storage pond that will be used as a non-potable water supply for vineyard irrigation and frost protection. This does not represent any new or increased use of water on the property, but rather an alternative source of water to replace a flashboard dam and direct diversion that are currently being used. The pond will be constructed using soil from on-site, and will be lined using a polyethylene liner. The pond embankments will be stabilized using engineered geotechnical methods, as well as native plants that will enhance the riparian corridor. The pond will be filled with water from a new groundwater well that is not hydrologically connected to the stream, and that will be drilled as part of this project. In order to comply with required setbacks, this project will also include the relocation of the septic system.
