Jakarta Should Have ( More of ) These

I think Jakarta should have these Grasscrete or similar solutions rather than too much hollow campaign about solving the flood problems… not sure how will it scale at cost ( for the budgetary inflating scumbags at construction contractor offices ), but as far as my logic can sense, it should be the same with laying out solid con blocks all over the parking fields. At least it can do good in providing more lawn mowing jobs to needy people.
