Mitigation Measure 4.9-5: Increased Wildfire Risk. An Open Space Fire Management Plan shall be prepared by developers of each lot which contains Open Space and shall be submitted to, and approved by, the Livermore-Pleasanton Fire Depa~:~ment prior to the issuance of occupancy permits for homes in the Specific Plan Area. The Plan shall propose specific measures to reduce potential fire hazards, including construction of buffers between homes and regular maintenance and disking, as appropriate. If appropriate, the Plan may also specify the planting of "wet bands" between the residential development and open space areas. All brush and other fiammable materials shall be cleared within at least 30 feet of homes. Ornamental landscaping shall emphasize the use of fire-resistant species. SIGNIFICANT EFFECT Impact 4.9-6: Hazards Posed by Steep Slopes. Steep channel banks along Arroyo del Valle and adjacent um'eclaimed aggregate mining pits filled with water may present attractive nuisances that could result in accidents and injury. This would be considered a potentially significant impact. Changes or alterations have been required in, or incorporated into, the project which mitigate or avoid the significant effects on the environment. Facts in Support of Finding The City of Pleasanton has adopted the following measures which will reduce potential public health and safety impacts to a less-than-significant level: Mitigation Measure 4.9-6: Hazards Posed by Steep Slopes. Six-foot high minimum fencing shall be installed at the border of the Plan Area along the steep banks of Arroyo del Valle and all mining pits within the Plan Area to reduce the potential for recreational use of the arroyo and water- filled mining pits. Signs shall be posted eautioning of steep, unstable slopes and potential drowning hazards. In addition to this provision, the stability of slopes along the arroyo shall be evaluated and modified, if necessary, to be made stable under short- and long-term conditions (see Impact 4.2- 2). SIGNIFICANT EFFECT Impact 4.9-7: Exposure to Disease-Bearing Organisms. The proposed project would attract additional people to residential areas near water sources (e.g., aggregate mining pits, creeks, detention basins, ditches, grassy swales) that can provide active breeding sites for disease- bearing organisms, potentially causing a disease transmission and an environmental nuisance problem. This would be considered a potentially significant impact. Changes or alterations have been required in, or incorporated into, the project which mitigate or avoid the significant effects on the environment.
