The heavy rain map shows where surface runoff, backflow from water bodies, or flooding from the sewer system may occur during heavy rain.
Help Needed
We are also asking for the help of residents and businesses. Anyone who has already experienced heavy rain or flooding can report their experiences via the “Heavy Rain Reporter” at www.starkregenmelder.de and, if necessary, submit photos of the damage. We are seeking information on the location, time, and nature of the flooding. A paper form to fill out is available for download at the bottom of the page. It is also available in print at City Hall. Reports from the public help refine the risk map and better identify particularly affected areas.

Identifying Risks
The heavy rain hazard map is intended to help identify risks early on and develop appropriate protective measures. The goal is to
- minimize potential damage as much as possible
- increase the safety of citizens, and
- strengthen municipal risk management.
At the same time, the map serves as a basis for planning decisions—for example, in the areas of construction, the environment, and disaster response. It is also intended to be integrated into existing plans, such as land-use or zoning plans.
Flash flood risk management is being implemented with funding from the Free State of Bavaria. Using computer simulations,
- analyze various heavy rainfall scenarios
- areas particularly at risk are identified, and
- appropriate protective measures are developed.
The city of Erlangen is being supported in this effort by SPEKTER, a consulting firm specializing in heavy rainfall. Once the heavy rainfall hazard map is completed (expected by the end of 2027), it will be presented to the public.
A paper form is available for download as a PDF at the bottom of the page.
This can be printed out, filled out by hand, and then submitted to the Office for Environmental Protection and Energy Issues at Schuhstraße 40, 4th floor.
Printed copies of the form are also available at the Citizen Information Desk on the ground floor of City Hall (Rathauspl. 1).
Since the PDF is currently not accessible, the responsible staff member from the Office for Environmental Protection and Energy Issues will be happy to assist you (Tel.: 09131/86-1864, Schuhstraße 40 / Room 411).
Feedback from the public helps to further refine the risk map and better identify particularly affected areas.
