Rusty in Minnesota says he builds streetside raingardens with replaced soils and an underdrain for $7 - $8lsquare foot. The qualifiers: • Most of the plants that go in them are plugs • the edging is the black plastic stuff • No walls around the gardens • The underdrain is a pipe wrapped in a filter fabric sock. He does not use a gravel layer For KC, I estimated that same price ($7/SF) for gardens that use native soils and no underdrains. A garden with replaced soils and underdrains might run $15 - 25 /square foot. I don't have a high degree of confidence in the latter number because we just have not built that many here yet. My calculations are attached. If you need to put together a pretty good cost estimate for your project, could help you come up with the line items to be included. But the unit costs would have to come from your area. nlj Raingarden construction cost est, 09.21.07.xls Best wishes, David This e -mail and any attachments are confidential.

Do you have any kind of table or anything already prepared that would show the range in rain garden costs in terms of construction and then also maintenance? Thanks, Krista
