Zálezlice town is one of the symbols of the most devastating flood from August of 2002. The flood barrier is proposed as a homogeneous earth dam dike of a maximum height of 5.35 m with clay-cement cut-off wall into the depth of 4.5 m. The total length of the dam dike is 1536 m. The dam dike also includes the design of two road cross-overs through the municipality, a gated culvert at the crossing of a nameless stream through the dam, a crossing for horses and accompanying environmental compensation measures (210 trees planed). The flood protection design in the inhabited areas included a cross-over of a set of networks including electricity cabling, gas piping and communication cables.

Responsible for the detailed design and supervision during construction period, as-built documentation, negotiation with local authorities and participation of the construction commission, project management.
