The rafting has an immense cultural and tourist significance for the city of Wallenfels and the entire Franconian Forest. Through the rides on the Wilder Rodach, the memory of the rafting is made tangible in a unique way. However, the survival of traditional rafting on the Wilder Rodach is acutely endangered, as climate change has led to increasing periods of persistent low water and more and more rafting has been eliminated in recent years. The city of Wallenfels intends to commission the planning and production of retention basins in the inflow area of the side valleys to the Wilder Rodach above the Schnappenhammer district in order to be able to guarantee traditional rafting even at low water runoff in the Wilder Rodach. Since their production as earth basins represents watercourse expansions, planning approval procedures under water law must be applied for. The necessary applications under water law are to be submitted to the district administrative authority in 2025. Several sites for the location of retention basins were explored by the Kronach Water Management Office. Locations 1 to 4 in Lamitztal and Kleinthiemitztal, which were initially favoured for a more in-depth investigation, are shown in the site plan for the present application. In addition to their function as a water reservoir for filling the dams for rafting in the event of persistent low-water periods, the retention basins will also have an ecological function by creating a permanent reservoir. Furthermore, it must be examined whether a fundamental low-water elevation can be connected to the retention basins during longer dry periods for the lateral waters and in the further course for the Wilde Rodach. Particularly in connection with the partly complete extinction of the spruce stocks in the aquatic valleys, the buffer basins also serve to store and delay the outflow of the now faster draining water due to the large bare areas now available. In addition, the project is also of enormous importance for animals and insects that rely on water. The reservoirs also serve as flood retention in the inflow streams to the Wilder Rodach and thus as protection for the city of Wallenfels, even if only to a subordinate extent. Water management and nature conservation are very positive about the project according to previous votes. The milestones for the implementation of the project envisage (subject to a positive funding decision) : - Start of service: June 2025 - Start of construction: 1st quarter 2027 - Completion: 1st quarter 2028 The total cost of the project (KG 500) is estimated at € 0.755 million per basin - a total of €1.55 million gross. The following services are intended to be contracted for this call for tenders: Services civil engineering structures, service phases 1-9 according to §§ 41 et seq. HOAI + services of structural design according to §§ 49 et seq. HOAI LPH 1-6. The services are ordered in stages. First, in the 1. Commissioning stage commissions the service phase 1-3 in accordance with § 41 HOAI. The power phases 4-9 (4-6 TWP ) are called up in stages. There is no legal claim to a total commissioning.
