Document Description
The project is limited to the following activities: 1. Removal of vegetation and sediment from the larger of two existing on-site ponds within WhiteRock Creek. 2. Removal and replacement of three on-site culvert pipes. 3. Improvements to the existing earthen levee between the two on-site ponds; and 4. Native riparian tree planting. Vegetation and Sediment Removal Vegetation and sediment removal will be conducted within the larger of the two existing ponds within White Rock Creek on the property. Prior to starting excavation, flows will be diverted around the work area by building a sandbag dam at the point where White Rock Creek enters the pond from the east and directing the flows through a pipe and into an existing culvert at the southeast corner of the pond. The remaining water in the pond will be pumped out using a floating water pump and deposited into the creek channel downstream. Once the work area has been dewatered, sediment and cattails will be excavated using heavy equipment. Approximately 400 to 420 cubic yards of sediment will be removed. The sediment will be deposited within relatively flat areas of the property away from the pond. The sediment deposit areas will be seeded and covered with broadcast straw. A berm may be constructed if necessary, to prevent migration of the sediment into the creek or pond. In addition, 10 willow trees will be removed from the banks of the pond. Culvert Replacement Three on-site culvert pipes will be removed and replaced with new corrugated steel pipes of the same diameters. Culvert 1 drains the larger pond and is 36 inches in diameter and 24 feet long. Culvert 2 drains the smaller pond and is 18 inches in diameter and 18 feet long. Culvert 3 is located within White Rock Creek at the western edge of the property and is 24 inches in diameter and 20 feet long. Levee Improvements Earthen material will be used to raise/level the levee running north-south along the western perimeter of the large pond. Approximately 100 cubic yards of earthen material will be used. Native Riparian Tree Planting To replace the 10 willow trees that will be removed from around the pond, native riparian trees will be planted around the larger pond and in an area to the south of the pond. Native trees will be planted within the replanting areas such that each tree is spaced approximately 10 feet apart
