Army Corps of Engineers, propose to construct the Hansen Dam Recreation Improvements Project. The project includes two components - 1) Kids Campground; and 2) Parking Lot/Restoration/BMP (AKA: Green Parking Lot) - subject to CEQA environmental review under this initial study.
The campground component includes construction of 12 temporary tent cabins with pads, as well as portable dining and kitchen facilities to accommodate up 60 campers and 10 staff members. A permanent restroom facility would also be constructed, 其中包括安装2,700英尺的新, 四英寸直径的下水道和升降站. 还包括一个圆形剧场, 篝火圆, as well as a small staff parking lot and drop-off area. For security, the perimeter would be fenced by 750-feet of concrete rail fencing. The design included a (two-inch diameter) potable water supply line, drinking fountains, and misters. Electrical lines and water services would be replaced or upgraded to meet current codes. A shade structure is a planned, but is not presently part of the current project scope of work. The campground would be operated daily during the summer months. 在今年剩下的时间里, the campground would be limited to weekend use for over-night camping with possibly some programs during the weekdays. 预计工程将于2010年冬末开始, 将于七月一日完成并投入使用, 2010.
The Parking Lot/Restoration BMP component includes construction of diversionary structures, 渗透/拘留盆地, 垃圾机架, 和vegetated-swales, 它会接收并过滤流入汉森湖的径流. Diversionary structures would be constructed in two existing arroyos, tributary to the lake. 除了, 低层停车场将被重新设计, where portions would be removed to make room for a vegetated filter strip, 植物的沼泽地, 和渗透/拘留盆地. The parallel access road, as well as the central and perimeter berms would also be removed. The remaining parking lot area would be re-stripped to accommodate existing capacity. 上层停车场将不会被修改, 但将由一个单独的, 但类似的, inlet/植物的沼泽地 和渗透/拘留盆地 system. 该项目还包括入侵性植物根除, and replacement with appropriate California native plant species. Temporary irrigation and protective anti-pest devices would be installed. 取决于可用资金, 工程范围可能包括停车场重铺路面, or barriers to deter vehicles from encroaching upon the wetland habitat. 预计9月15日开始施工, 2010, 将于3月15日完工并投入使用, 2011.
