Wait ‘til re­hab works are done, CDRRMO told

Sun.Star Davao - - TOP STORIES -

THE Mines and Geo­sciences Bu­reau 11 (MGB 11) ad­vised the Davao City Dis­as­ter Risk Re­duc­tion Man­age­ment Of­fice (CDRRMO) to wait for the com­ple­tion of De­part­ment of Works and High­ways 11 (DPWH 11)'s re­ha­bil­i­ta­tion ac­tiv­i­ties in the af­fected area of Shrine Hills be­fore al­low­ing evac­uees to re­turn to their homes.

Dur­ing the Con­nect press con­fer­ence yes­ter­day, Oc­to­ber 13, 2017 at SM Lanang Pre­miere, MGB 11 Ge­ol­ogy Di­vi­sion chief Bev­erly Bre­bante said CDRRMO asked MGB 11 for an ap­proval if it is al­ready safe for the evac­uees to re­turn to their homes.

Al­most 40 fam­i­lies were evac­u­ated last week due to im­mi­nent dan­ger of land­slide at Shrine Hills last Oc­to­ber 5.

"DPWH 11 is con­duct­ing sev­eral re­ha­bil­i­ta­tion con­struc­tion along the af­fected area such as putting up of Gabions or wire work con­tainer filled with rocks, con­crete, and other ma­te­ri­als to help sup­port the slopes, as well as the spray­ing of shot crete or con­crete to harden the wall blocks," Bre­bante said.

Such ac­tiv­i­ties have to be fin­ished first be­fore al­low­ing the evac­uees to

re­turn to as­sure that their homes will be pro­tected from any pos­si­ble ero­sion that might hap­pen in the fu­ture.

She said the area where the land­slide oc­curred is still con­sid­ered hab­it­able if the land will be de­vel­oped with mit­i­gat­ing mea­sures to sta­bi­lize it soil com­po­nent and re­duced its vul­ner­a­bil­ity from land­slide. The ma­jor soil com­po­nent present in the hills is silt gran­u­lar sed­i­ments com­mon in bod­ies of wa­ter and sus­cep­ti­ble to soil dis­rup­tion.

With the pos­si­bil­ity that the on­go­ing re­ha­bil­i­ta­tion ac­tiv­i­ties of DPWH 11 may re­sult to another oc­cur­rence of land­slide, Bre­bante said MGB 11 does not rec­om­mend the de­part­ment to dis­con­tinue its con­struc­tion as such may re­sult to dam­ag­ing ef­fect.

"Since DPWH 11 al­ready started its ac­tiv­i­ties, the soil is not any more sta­ble so they re­ally have to fin­ish what they have started," she said.

MGB 11 is in con­stant di­a­logue with DPWH 11 re­gard­ing its re­ha­bil­i­taion ac­tiv­i­ties to as­sure that it will not worsen the sit­u­a­tion at Shrine Hills.
