Offenbach am Main (Hessen): City presents new main dyke plans

Offenbach – The main dyke is being renovated and upgraded. Moments… did we not have this announcement several years ago?

Offenbach – In fact, the 18.7 million project is like one of those stories that have been forgotten over time and want to be told anew: After a violent discourse in parts of city society about the design of the dike, a (tough) Compromise enforced. The regional council overturned this – mainly because of a very long dam opening in front of Isenburg Castle. The administration will present the “overplanned plans” to the citizens on Thursday evening. The interest is negligible.

A good two dozen listeners take a seat where the Parliament normally meets. The sandwiches and pretzel sticks would have been enough for ten times the number. In the plenary there are five city councilors, seven Rumpenheimers and five citizens who live between Main and Berliner Straße. In other words, in the area where Offenbach’s lowest point is most and most affected by floods and heavy rain. A “uniform level of protection” is now to be achieved between the Carl Ulrich Bridge and the Allessa site, which protects the inner city from a flood that arises every 200 years. Or – given the global climate change – possibly more often.

Offenbach: Main dyke renovation costs millions

To make a long story short: All discussions as to whether renovation and upgrading of the dike are necessary (a listener calls it “overingenieurt”) are no longer relevant. The country has ordered it, if necessary the regional council will take over the project. A scenario that the city of Offenbach wants to prevent at all costs in order to be able to influence the design at all. It is also good that there were significant time shifts in the end. According to the head of planning, Paul-Gerhard Weiß (FDP), the city is expecting costs of almost 19 million euros, around 6.7 million more than when it was presented in 2012. “However, at least 80 percent can be funded. As a result, the urban share increases only slightly from 8.6 to 8.7 million euros. ”

Over and over? This cannot be said uniformly for the tree population; in some places the double row remains, in others the main or street side is felled, or there is a clear cut with the following new planting. Photo: Kuhn

The new plans are now available to the RP in Darmstadt, and the city is expecting a decision by the end of the year. The officials are sure to take a closer look at two points: the crossings on Schlossstrasse and Herrnstrasse, which are supposed to bring a (gentle) opening of the city to the river – Offenbach am Main, not just as a place name.

Offenbach: Main dike should become significantly wider

This is planned: The Deichtor on Schlossstraße is to be rebuilt, the passage widened from the current 5.50 to 15 meters and increased from the current 2.20 to 2.50 meters. In addition, access to the dike promenade, which is currently only possible via two stairs, should in future also be possible on one side (towards the Mainpark) via a barrier-free ramp. A public toilet facility is to be built under the stairs. In the event of flooding, a mobile dam is planned in front of the Deichtore entrance on the side of the Mainstrasse. The new planning also provides for a new solution for access to the Main at Herrnstrasse. There, the steep stairs are to be replaced by a seven-meter-wide, barrier-free combination solution consisting of stairs and ramp.

Rethought: The transition from Herrnstrasse should be about 7.50 meters wide and barrier-free.

According to Manfred Reißmann, the organizer of the weekly flea market, this is not well thought out. “The toilet is badly placed, it has to go to Speyerstrasse,” he thinks of his feeders and buyers. It does not work! For reasons of cost, the city uses an “existing building” for the public locomotive, one would have to talk about a second system later. Only this much is certain: quiet locations are not permitted on the mains side.

And the sticking point trees? Of 250, 141 have to fall, 135 are replanted from tree species “that are suitable for the location and, according to current knowledge, are best adapted to the changed climate conditions”. Landscape architect Ulrike Stockert promises: “The new trees have better conditions than the old ones because they are filled with substrate.”

This message doesn’t reach everyone. The first of the few listeners have already left.

The city of Offenbach receives funding from the State of Hesse for urban planning projects. However, not everything can be implemented because there is a shortage of personnel.
