How to get Zhimin Road Residential District from Chengdu Shuangliu Airport by bus?

Hi! I've booked room in the H-hotel Riverside which is situated in Zhimin Road Residential District. I've read about shuttle buses but didn't quite understand their routes. So questions are: Which bus number is suitable to get Zhimin Road Residential District? On which bus stop should I get off the bus? What is approx ticket cost?
And what is the place called "Huaxi Dam"(I could not find this place on Google maps)?

Thanks!
