3 Memo Date: Project: To: From: 20July2017 Nebraska Game and Parks Commission Schramm State recreation Area River Access Sarpy County, Nebraska Floodplain Administrator John Cambridge. HOR Subject: Flood Plain Development Permit Application The Nebraska Game and Parks Commission (NGPC) wants to improve recreational boating access along the Platte River and is proposing to construct a river access point for canoes and kayaks at the Schramm Aquarium State Recreation Area near Gretna, Nebraska, see Figure 1 - Vicinity Map. The proposed project would be located on the Platte River, near the east entrance to the park on Highway NE-31. The proposed project is located in Special Flood Hazard Zone AE; a portion of the Platte River where Base Flood Elevations have been determined by the Federal Emergency Management Agency (FEMA). Based on FIRM Panel 31025C0165G, the proposed project is at the edge of the Platte River floodway, and is in the extraterritorial jurisdiction of Sarpy County, Nebraska. Development in the floodplain must obtain a Flood Plain Development Permit. The proposed project includes a slope excavated into the left (north) bank of the Platte River, constructed such that the slope does not extend above the existing ground. See Figure 2 - Site Plan and Figure 3 - Project cross-section. Since project components do not project above the existing ground line, no hydraulic modeling will be performed. It is my opinion that the proposed project would satisfy the criteria for development in the floodplain criteria. The boat ramp and parking lot are at or slightly below the existing ground line and there will be no changes to the river cross-sectional area at the proposed project site. The proposed stream crossing is in the non-conveying portion of the river cross-section, is below the overbank ground elevation,. On behalf of the NGPC, we are requesting your review and consideration for approval of the attached Sarpy County, NE Flood Plain Development Permit Application for construction of the proposed boat launch facility at the east edge of the Schramm Aquarium State Recreation Area.
