Municipal Water Supply Well Site Feasibility Assessment and Preliminary Test Well Design

Hamilton Branch Community Services District requires a supplemental water source to supply customer needs. Engineers have determined that the ideal location is adjacent to the District’s fenced compound that houses water tank A-13. The proposed project consists of the following elements: contractor mobilization to project site and equipment staging; installation of estimated 12-inch conductor casing; drilling of 6-inch diameter bore hole to a depth of about 500 feet; perform geophysical surveys in bore hole; construct a temporary on-site retention basin (made by digging a depression and/or using soil to create berms); install submersible test pump and test pump well to assess aquifer yield and groundwater quality discharge water to temporary storage tanks and on-site retention basin; upon completion, abandon borehole in accordance with State and local regulatory requirements; and contractor demobilization and site restoration. Project location details: In the town of Hamilton Branch, north of Lake Almanor near the intersection of Plumas County Road A13 and Foxwood Drive. The property is a 97.9-acre parcel (APN 103-140-044) (the Property). The proposed test well is adjacent to the District’s fenced compound that houses water tank A-13 (see attached Exhibit). In total, the project area is less than a quarter of an acre.
