Silky oaks will also clog up your drains, and the leaves make a huge mess.

Leighton pines will grow real quick, not sure if native, but might grow taller than you need.
JLo already mentioned this
I wasn't aware though, wherever we've had them or are growing in the district is all rural so drains to be a problem to.

Leylandii are notorious for canker around here, but the studs like to use them as screens.
