The project site consists of four parcels totaling approximately 128.5 acres, located along the northwestern boundary of the City of Pleasanton. Currently, two single-family homes occupy the eastern portion of the site. Ponderosa Homes II, Inc. proposes to develop the site with 30 single-family detached residences - 28 new homes (Lots 1 through 28) and the replacement of the two existing homes (Lots 29 and 30). Additionally, approximately 70 acres, representing about 55 percent of the total site area, would be dedicated to the East Bay Regional Park District (EBRPD) for use as publicly accessible open space. Figure 1 shows the project location.
