Replace Restroom and Shower Building and Relocate Campsite

Replace Restroom and Shower Building and Relocate Campsite

Provide a restroom and shower building that meets ADA standards to replace previously demolished non-ADA-compliant building at Hidden Springs Campground in Humboldt Redwood State Park. The new building will be placed on the footprint of an existing campsite, which will be relocated to the footprint of the demolished building. The new building will be approx. 290 sf and employ flow fixtures and other water conservation measures to reduce water flow to less than existing. The project will also require the following associated site work: 1. Construct new ADA-compliant parking site and path of travel to new building and new ADA-compliant campsite, including the construction of a wooden pedestrian overcrossing (+/- 10'). 2. Provide new ADA-compliant sidewalk. 3. Removal of asphalt from old ADA-compliant parking spur. 4. Removal of several timber curbs. 5. Removal of three trees less than 12" dbh. 6. Some minor grading (fill) around the building and in the path of travel will be required. Existing utilities will be extended to new building. These utilities will include approximately 80' of new sewer line to existing septic tank, 120' of underground electrical line from existing electrical service, and 140' of waterline (overground) from existing waterline. Work will comply with the following conditions: 1. Construction activities that result in the generation of noise above the ambient levels will occur outside of the northern spotted owl and marbled murrelet breeding seasons (Feb. 1 through Sept. 15). 2. Contractors or individuals involved in the construction of the facility will be instructed by the project manager on proper disposal and policing of trash and food within the project area. The contract will stipulate that contractors will be responsible for keeping the work area free of trash (especially food or other items that may attract corvids). 3. Roots greater or equal to 1 inch in diameter will not be impacted by any excavations. If necessary to excavate in areas with tree roots greater or equal to 1 inch in diameter then it will be done by hand so as not to damage the roots. 4. A qualified engineer will develop plans that address the potential for chronic slope movement on the integrity, safety and maintenance of the project infrastructure. Drainage controls will be developed as part of this planning effort. 5. Septic system design will consider the potential for slope movement and related impacts on water quality and will also consider the potential for the effluent to caused localized saturation that may impact the stability of the proposed construction site or other sites within the campground. 6. Guidelines in the Erosion and Sediment Control Field Manual for Construction will be used as Best Management Practices for controlling off-site sedimentation and incorporated into any contract for work. 7. Emergency response will consider the needs of less mobile individuals at this location.
