I agree with Loire and Taylor. This going to cause even worse traffic issues on 40th Place and the historic streets of Hamilton, Gallatin and Farragut. My family also does not like the high density in this tract and demolition of a very historic property.
Furthermore, individual homeowners in Hyattsville have to jump through hoops in order to get permission for additional lot coverage for home additions on 7500 square foot lots, but a developer can almost entirely cover these lots with townhomes and other homes that all look similar? It doesn't make sense and does not promote smart growth.
If such high density is what the community wants (though I don't), then infrastructure needs to be in place to support it, such as increased bus service to the metro station, making 40th Place a one way street and more police enforcing stop sign running and other traffic issues, a bigger elementary school, etc.
