How to deal with a drainage problem along the side of our house?
We have a 1950s house in Saskatoon, SK, Canada (climate = warm summers, very cold winters and ~ 350mm moisture/year). Our neighbours re-built their house and the landscaped surface is now ~12″ higher than ours (about level with our stucco siding). One of their downspouts also drains directly onto our property (don’t ask). There is 3 ft between our outside wall and the property line. They have a concrete sidewalk between their house and the property line.
We have had several suggestions for dealing with drainage on our side:
a) pond liner + 6″ crusher dust tamped every 2″ and sloped towards the neighbour as well as towards the front of the house (property drains to the front)
b) weeping tile with landscape fabric and gravel
c) excavate to clay (remove topsoil) and add 2″ base gravel with clay sloping towards neighbour and to front of house.
Any suggestions as to which, if any, of these makes the most sense? If not, any other suggestions are welcome.
