Taipei City Government authorizes the technician to the governing slope communities for the regular investigation and inspection check every year. (The frequency of investigation will increase in case of typhoon and earthquakes.) Once there are any unusual signs discovered by the technician, Taipei City Government will notify and suggest the slope communities to improve immediately. Besides, the citizen of the slope communities which are not governed by Taipei City Government may also contact us if having any safety concerns. (Contact number: 27591228)
