Document Description
CDFG is intending to execute a Lake and Streambed Alteration Agreement pursuant to Section 1602 of the Fish and Game Code (SAA # 1600-2008-0318-R5) to the project applicant, JRH Real Estate. The Applicant proposes to remove accumulated silts and vegetation from the basin of an existing temporary desiltation feature. The feature has an inlet channel and total basin area of 13,000 square feet (0.3 acre). The bottom of the feature in intended to retain storm flows, but for exceptionally high rainfall, an outlet was created. Normally, the flows are retained and percolate through the basin bottom or are lost through evapo-transpiration of the associated freshwater marsh vegetation, i.e, cattails (Typha domingensis) and scattered willows (Salix lasiolepis). No sensitive plants or animals occur within the feature. Since its creation, the basin has been invaded by several non-native plants including cardoon (Cynara cardunculatus) and salt-cedar (Tamarix parviflora). The removal of vegetation from the desiltation feature will include the removal of these invasive non-natives. A peripheral ring of cattails and willows will be retained on the edge of the basin to allow recolonization by these plants between clearing events.
