Since Ta An is some distance from the Tamsui river, it was not until the Yung Cheng era (the third emperor of the Ching dynasty) that a start was made on development of the area.
但有史可考者，則是在清康熙四十八年（西元一七○九年）時，當時有個福建泉州人，叫做陳賴章的，向清廷申請到了正式的開墾執照。大安區當時大約也是由福建人開拓的，因為它離淡水河比較遠，所以開發得比較遲。開拓之始大概在康熙末年，到了雍正時代，才大致有了規模。
