Is this a type of grass or a weed
We actually think that it is a clump of turf-type tall fescue, which is the recommended type of grass for our area. It is the surrounding area that may need to be renovated or re-seeded. That area may be a mix of fine fescues and perennial rye, which don't do well over time, but are often included in less expensive seed mixes.
You may want to get a soil test done and think about overseeding or renovating this late summer into fall. Here our lawn page, which includes information you need to do this. http://extension.umd.edu/hgic/plants/lawns
