7 r~dg engmeenng September 23, 2015 RDG Geoscience & Engineering, Inc Sapp Bros Dr. Omaha, NE T (402) F (402) Sarpy County Planning and Zoning Department 1210 Golden Gate Drive Papillion, NE RE: No-Rise Floodway Certification Ken and Sharon Meyer Residence "d St, Lot 39E Gretna, NE Dear Sarpy County Planning and Zoning, This letter contains a No-Rise Certification and supporting documentation for the residence on the above referenced property. The technical justification for the floodway no-rise certification is as follows. The residential structure on the property is aligned with the shorter width perpendicular to the direction of river flow. The width of the house (approximately 20 feet) is only a small fraction of the entire flood channel width (approximately 6500 feet). Thus, only a very small volume of the overall flow through the flood channel need to be diverted around the structure in case of a flood event, which would not impact the height of the flood waters. The residential structure is located within a very shallow area of the flood channel. Thus, only a very small volume of the overall flow through the flood channel need to be diverted around the structure in case of a flood event, which would not impact the height of the flood waters. The residential structure is located on an elevated surface with a crawl space underneath. In the case of a flood event, water would flow beneath the house. Although the current residence has occupied the residence for only a few years, he has indicated that there is no evidence of past inundation on original parts of the residential structure (such as water marks on studs, walls, or insulation). Thus, there is no historic evidence of flooding to the level of the structure that is above the elevated foundation. A FEMA Flood Insurance Rate Map and for the area and No-Rise Certificate are attached. Please do not hesitate to contact me at with any questions. Sincerely, Robert Kalinski, P.E.
