Hi. I have a section of lawn, about 10' x 60', near the street where the topsoil is very thin & it produces a lot of weeds. I want to spread about 3 - 4 inches of topsoil on it & seed it. What's a good way to make sure the weeds don't continue to grow?

A healthy thick lawn is the best way to keep weeds away. You can't use pre-emergent products with a newly seeded area, so it's likely the weeds will come up with the grass at first. Once the grass gets well established it should choke out most of the weeds and you can apply weed control products to take care of the rest.
Since you're going to be putting down topsoil, I would kill all the existing growth with Roundup. A week later, you can mow it short, then put down the topsoil and reseed. Don't know where you are located, but it's getting late to start this now here in the northeast. It will need a lot of frequent watering as the temps get warmer and there will be more competition from weeds.
Early fall is by far the best time to do this type of project.
I'm in Nova Scotia. We had a little snow on the weekend, which is not all that unusal, so it'll be a while before we have any hot, dry weather. I keep reading where the fall is best for this but our falls are typically much drier than April, May & June so I don't know if that applies in this region.
Thanks for the response.
