Answer: Depending upon the grass type you're growing, it may come back with a little encouragement in the form of water and a springtime feeding. If not, rake the area to remove the dead grass and roots, then sow grass seed over the bare soil. Grass seed germinates in 7-10 days if you keep the area moist (but not soggy wet). To help keep the seeds and seedlings moist, you can cover the freshly sown grass seed with a thin layer of compost or peat moss.
If you can determine what kind of turfgrass you're growing (take a sample to your Cooperative Extension or local nursery) you can purchase seed of that variety and by summer's end you won't be able to tell which was original grass and which was newly seeded.
Hope your sprinkler system remains healthy this summer!
