The influence of the Tama River flooding More than 200 playgrounds on the riverbed It is not available now and December 11 16:44

It will be 2 months in 12 days from Typhoon No.19, which caused great damage to various places. Due to the flooding of the Tama River, more than 200 baseball stadiums and soccer fields in the riverbed are still unavailable in the basin.

In October Typhoon No. 19, many athletic facilities and parks have become unusable due to the flooding of the Tama River, with mud and sediment flowing into the ground of the riverbed and the accumulation of driftwood.

When NHK interviewed, there were 206 baseball stadiums, soccer fields, and tennis courts in 32 facilities in 16 local governments in Tokyo and Kanagawa.

By municipality,
▽ Tokyo Ota Ward is the most, including 79 baseball fields and tennis courts,
▽ Next, Kawasaki City has 41 baseball fields and athletics fields,
▽ Tokyo Akishima City, including 19 softball fields and tennis courts,
▽ Setagaya Ward has 15 baseball fields and soccer fields.

Some local governments have begun construction to remove accumulated sediment and garbage, or repair facilities, but the scope of damage is wide, so restoration is expected to be at least as early as next spring.

Furthermore, since there is a risk of repeated damage from the increase in the Tama River in the future, some local governments are considering reducing facilities based on financial costs, and the operation of sports facilities that utilize riverbeds has become an issue. .

Futakotamagawa Green Field Sports Ground in Setagaya-ku, Tokyo

Of these, Futakotamagawa Ryokuchi Stadium in Setagaya-ku, Tokyo has 15 baseball fields and soccer fields, and the annual number of users is approximately 150,000, but it is still unusable.

Among them, the baseball stadium is covered with earth and sand by about 70 centimeters, and the net struts surrounding it are also laid down and driftwood remains entangled.

Work is being done to remove soil and survey at the site, but priority is given to lightly damaged ground where work can be completed by the rainy season next year, when the river may increase again.

As for the places where the damage is large, it is necessary to consider the recovery method and equipment in the future whether the damage will be caused by the increase in water.

Takeshi Sudo, Manager of the Sports Promotion Section of Setagaya Ward, “There has been damage from typhoons and heavy rains that caused sand and soil to flow out, but there has been no damage to the accumulation of mud and driftwood. It is necessary to consider measures to prevent the same damage after recovery. "

Tokyo Fuchu General Gymnasium

In Fuchu City, Tokyo, a general gymnasium more than 300 meters away from the riverbank is closed because the underground electrical control room is flooded and lighting, air conditioning, and water supply facilities cannot be used.

According to the city, at the time of Typhoon No. 19, the area around the gymnasium was not flooded, but the electrical control room equipment on the second basement floor was broken due to water leaking from the ceiling.

The water pressure in the Tama River and the pressure drop due to the typhoon have increased the surrounding groundwater level and water leaked from cracks in the concrete.

The recovery is expected to take about a year, and the Austrian table tennis team was planning to use this gymnasium at the Tokyo Olympics camp, but it will be accepted at another gymnasium.

Mr. Keiichi Ichikawa, Director of the Fuchu City Sports Promotion Division, said, “I want to make a detailed investigation on the cause of water leakage and take measures to prevent damage recurrence, such as taking measures to prevent water damage.”

Sports organizations chased by correspondence

Sports organizations that were active on the riverbed grounds are busy responding to the scheduled tournaments.

Of these, the Setagaya Football Association canceled the league match this year with 124 teams from junior high school students to seniors, leaving more than 30% of the matches in October.

In addition, the resident convention held from August to December has changed the venue, and the period has been extended to two months until February next year.

“The next year's league game is scheduled to start in April as scheduled, but we have heard that there is no prospect for the recovery of the soccer field, so we should consider reducing it. I would like to expect early resumption in cooperation with. "
