Glonn is looking for solutions so that it does not lead to a flood disaster like back then.

It's been 20 years since severe flooding hit the municipality of Glonn.
Nothing has happened since then - neither a new catastrophe, nor a major breakthrough in flood protection.
Glonn - The Bavarian spoonwort is a dainty and rare beauty.
Highly endangered, it shows its shy, white flowers only in a few locations in the Bavarian Alpine foothills.
A model stock, carefully guarded by nature conservationists, grows in the Kupferbachtal near Glonn.
And with that, the spoonwort joins the many factors for which almost nothing has happened in Glonn in terms of flood protection since the catastrophic flood of 2002.
According to estimates by Mayor Josef Oswald (CSU), the municipality has so far invested 250,000 to 300,000 euros in corresponding plans.
Worried about detention basins, flood channels and bridge freeboards.
The Aquasoli planning office has been working on the big hit since 2007.
In the most recent municipal council meeting on Tuesday, its engineer Bernhard Unterreitmeier admitted: "We are actually back where we were in 2019." To correct himself a quarter of an hour later in the face of the debate: "Where we were in 2012."
Possible flood protection measures under discussion: Difficulties on all sides

Ten years ago, the office classified “planning variant 1” (there are six in total, plus two sub-variants) as the most sensible. Three retention basins are planned for any masses of rain: at the Augraben and for the Kupferbach near Reisenthal and a little further in the direction of the town. But there are difficulties with the residents, the farmers and the spoonwort. Numerous authorities have a say – their mills grind slowly.
Recent volte: The eight to ten meter high dam that may have to be built near Reisenthal could have an impact on the flow of cold air towards Glonn.
In addition, it was unclear whether such a major intervention in the FFH protection area and the forest would even require approval - and if so, would it be eligible for funding.
The protective measures are likely to cost around ten million euros.
Without 65 percent assumption of costs by the Free State for the municipality hardly to be lifted.
The result: a one-year planning freeze from the end of 2020 to the end of 2021 with a cautiously optimistic outcome.
Again and again new delays: back and forth with proposed solutions
The Flood Plan: The preferred solution is three retention basins (HRB) south of Glonn.

For SPD/KommA councilor Johannes Reiser, this was a reason to wring his hands at the meeting: "How should Glonn get on there?" he asked in view of the ever-new problems and delays. Mayor Oswald signaled that he wanted to continue along the long path of small steps. And raised the prospect of another hurdle: "Somebody will complain in the end anyway." Conservationists in favor of the spoonwort, which could harm the waterlogging, against the community. The community against the district office if they don't get a permit. These and other types of games are conceivable.
Speaking of varieties: Several local councils were able to gain new charm from a solution debated years ago: an underground drainage tunnel from the Kupferbachtal eastwards into the Glonn.
The planner has concerns because retention basins are also required for this and the costs could be enormous.
At around 6000 euros for a rough estimate, it is no longer important, according to the consensus in the municipal council.
In addition to variant 1, the tunnel is now being checked.
Nobody mentioned a time horizon until construction at the meeting.
