More than a year after Typhoon Ulysses’ landfall on the Philippines in November 2020, residents and officials of Brgy. Tumana, Marikina City are building taller houses and planning to put up flood markers. The flood markers will help warn citizens of future floods’ water levels, complementing the public address system (PAS) in the area.

With the water level at Marikina River reported to peak at 22.0 m according to Marikina’s Public Information Office (PIO), hundreds of residents in Brgy. Tumana were forced out of their homes during the onslaught of Ulysses. Tumana’s experience with the typhoon urged barangay officials to strengthen their disaster risk reduction and management (DRRM) by putting up flood markers in the area.
According to barangay secretary, Raymond Parta, Tumana’s officials plan to place flood markers around the barangay to help warn citizens of future floods’ water level or if there is a need for evacuation. The flood markers will complement the existing PAS in the area, especially in cases where the PAS cannot be heard.
Parta explains that when the water level at the Marikina River reaches a height of 16 m above sea level, Tumana’s residents are alerted of a forced evacuation through a siren in the PAS. The siren can only be heard within 1.5 km and cannot cover the entire 180 ha land area of the barangay. Hence, the flood markers will serve as a warning system if the PAS cannot be heard or is disrupted by strong winds.
After Ulysses, Parta states that many residents are also turning their bungalows into multiple-story or stilt-type houses to protect them and their belongings against floods. They do this because the barangay is susceptible to floods as the second lowest-lying barangay in Marikina with the Marikina River passing through some of its areas.
In a 2018 study by Mr. Nick Espina, urban planner and senior lecturer from the University of the Philippines, he explains that about 100 ha of the barangay is directly affected when the Marikina River overflows. Flood heights reach a maximum of 40 ft in these areas.
Parta points out that along with the building of taller houses and the plan to put up flood markers, Tumana maintains other DRRM measures like conducting seminars and providing “go bags” with equipment such as a whistle, flashlight, and first-aid kit. Tumana’s officials also continue to update a Facebook group called “Liga ng mga barangay-Marikina chapter Konsehal/Kapitan Ziffred Ancheta” where DRRM and other Brgy. Tumana-related matters are posted. The Marikina LGU continues to provide Tumana with a public address system (PAS), rescue boats, evacuation centers, and an online rescue page called Marikina Rescue 161.
