The GPS road mapping of Valencia started on April 10, 2014. Due to it being a holiday, the mapping team was welcomed by Engr. Nino Salvacion alone and had to map roads on foot using printed maps. On April 11, the team met with the Mayor and mapped roads in several barangays using a multicab. They observed various road conditions. On the last day, April 12, the team finished mapping remaining roads including the provincial road, presenting their work to Engr. in the afternoon before receiving honorariums and leaving satisfied.
