This is a site plan drawing for infrastructure improvements at the North Rim of Grand Canyon National Park. The plan, prepared by HDR Engineering, Inc. (prime contractor located in Denver, CO) under the direction of J. Glover Gough, depicts the Roaring Springs Pumphouse facility and associated utilities serving the North Rim area. Key features shown include silt fencing (119 linear feet), sediment control logs (2 locations, 300 linear feet total), electrical enclosures, a transformer, utility alignments connecting to RSPH (Roaring Springs Pumphouse) and MANZANITA Power Distribution, and multiple control points (CP1-CP16). The plan references multiple volumes of detailed specifications and control documentation. The drawing is Sheet 11 of 113 in the full set of contract documents, with a scale of 1" = 20' and indicates this is a General Environmental Compliance (GESC) Plan dated June 2024. The project involves site preparation, erosion control measures, and utility infrastructure coordination at this remote National Park Service location.
