This hilly subarea contains 198 acres or 52 percent of the Plan Area. It is characterized by individual homes located on hillside lots . Lots in this area generally average 20 acres in size and contain a single home. Most of the homes are accessed by long private driveways originating at Vineyard A venue. D. SITE CONSTRAINTS AND OPPORTUNITIES A fundamental element of the Specific Plan preparation process was an analysis of the developmental constraints and opportunities created by the physical characteristics of the site. The Plan has evolved substantially in response to these . The following text summarizes the site characteristics that present constraints to the location and type of development that might occur in the Plan Area, as well as the opportunities for potential future development. 1. Constraints The Plan Area is subject to a series of physical constraints which impact its developmental potential. These include the following : • Property lines. The Plan Area is divided into 33 lots which may present difficulty for some owners wishing to develop independently and in a timely manner. • Landfill. The old Pleasanton landfill is located on Lot 14. This facility was closed in 1976 , but it still presents potentially major constraints to development relative to land settling and the removal of methane gas . These constraints limit the location, type , and density of potential land uses that might otherwise be developed on the site. • Quarry noise, vibrations, and dust. The RMC Lonestar quarry operation is situated immediately north of the Plan Area. Noise, vibrations, and dust from this facility currently impact some properties within the Plan Area. • Mining. Lots 21, 32, and 33 contain aggregate resources which are entitled to be mined pursuant to an Alameda County Mining Permit and an approved reclamation plan. This could negatively impact proposed on-and off-site land uses. • Topography. South of Vineyard Avenue, the terrain varies from moderate to steep slopes which limit potential development. • Wildlife habitat. Three partially vegetated stream channels extend in a northerly direction to the Arroyo del Valle which provide corridors for the movement of wildlife. Significant areas of oak woodland provide additional valuable wildlife habitat. Disruption of these areas by development could adversely impact wildlife. 13
