Sump Pump drainage problems outside of house

I live in Kingston Ontario Canada. We live in a neighbourhood that has poor drainage. We are the lowest point of the road. Half the road has had a separation of storm line from sanitary line. The separation stopped just before our house and is scheduled to be done next year. Last fall we had a sump pump installed due to flooding from heavy rain. We then had to have our water line and sanitary line replaced from our house to the city line, due to crumbling pipes. At that time, we were told that we should have a storm line added, capped at both ends. Then, when the City has separated the storm from the sanitary line next year, our storm lateral would connect our sump pump directly to the storm drain.
We had a problem last winter, due to the sump pump pumping out a lot of water, causing water to run down to the sidewalk, which becomes a huge liability if someone falls.

We've been told by neighbours, that by connecting our sump pump to the storm lateral, we leave ourselves open to a huge problem of flooding, should the storm back up. We figure we would have to put a backflow valve on this line to prevent a problem. We have already added a backflow valve to our sanitary line to prevent sewage backup.

My question, based on this information is, is this too big a risk doing this. Or is it better to have our sump pump connect to a big O that is run underground to the back yard, so that water goes away from the front. Again, is this going to cause another problem like the water freezing in this pipe. I've been told that if the pipe is at a downgrade, it should'nt happen.

Any ideas?
