Including the 5 detached garages, a studio, and the 2-acre community park that was part of the original neighborhood design, there are 26 resources: 22 contributing buildings and 1 contributing site (park), 2 non-contributing buildings and 1 non-contributing site (Lot #17). The development remains heavily wooded, and both the houses and landscape retain integrity.
