ZAGREB, July 26, 2020 — Did an outdated stormwater drainage system cause even more damage during the Zagreb flood on Friday? Recently-elected Croatia MP Tomislav Tomašević of Možemo! (We can!) is seeking answers.
Tomašević announced on Saturday that he would request a report on cleaning the drains and maintaining the urban stormwater drainage network. He would like to know if the blockages in the system caused even more damage during Friday’s storm in Zagreb. The MP added that Zagreb must plan for future extreme weather events due to climate change.
“We will ask Mayor Milan Bandić to submit this report at the next session of the Zagreb City Assembly,” Tomašević told Hina on July 25, 2020.
Varaždin: More Rainfall, Less Flooding and Damage
“There was a very high concentration of precipitation in a very short time. But if we compare the rainfall in Zagreb with Varaždin, then it is obvious that something is wrong. Specifically, there was significantly more flood damage in Zagreb compared to Varaždin,” he added.
Tomašević adds that the stormwater drainage system in Zagreb cannot withstand this level of strain because it is too old. On the other hand, we have more asphalt and new buildings which connect to the system. We also have fewer green areas which can absorb rainfall, he points out.
Zagreb Must Plan for Extreme Weather, Climate Change
“From this perspective, we need to think about how to modify the system for the challenges of climate change. Unfortunately, there will be even more such extreme weather conditions,” Tomašević explained.
He added that the deforestation of Medvednica does not help, where catchment waters and erosion continue down toward the city. This creates even greater pressure on the stormwater system.
