The proposed project deals with flood protection of the village’s Intravalan by adjusting the Ondavka flow. The Ondavka flow adjustment will ensure the flow of Q100 and thus increase the flood protection of the municipality and enable its territorial and economic development. The project will protect 14 people at immediate risk from flooding and prevent flood damage in excess of EUR 3.77 million. The implementation of the project will ensure anti-flood treatment of the Ondavka stream with a total length of 705 m. The bottom niveleta is connected at the beginning and end of the adjustment to existing bridge structures with the fact that there will be purification of the trough in these sections. By increasing the flow profile and building a continuous fortification of the rectangular and trapezoidal cross profile, the risk of flooding during the spring melting and intensive rainfall will be limited, ensure anti-erosion protection of slopes and improve the aesthetic function of the flow as part of the village’s intravalve. One-stage project documentation solves the realisation of construction without building objects as one functional unit, which does not require further breakdown into building buildings.
