III. ENVIRONMENTAL SETTING AND IMPACTSD. HYDROLOGY AND WATER QUALITYTABLE III.D-1SUMMARY OF MANAGEMENT POLICIES RELATED TOWATER QUALITY PROTECTIONWater Quality (WQ)WQ1 Prevent the introduction of pesticides and chemicals into the water supply by minimizing andcontrolling the use of these constituents.WQ2 Restrict aerial broadcast spraying of pesticides as a means of vegetation management/pest control.WQ3 Minimize nutrient loading to the water supply.WQ4 Minimize the introduction of disinfection by-product precursors to the water supply.WQ5 Minimize the risk of metals leaching to waterbodies and prohibit dumping of metals.WQ6 Prevent the introduction of asbestos fibers into the water supply.WQ7 Prevent the potential for hazardous materials spills into the water supply by controlling their useand transport within the Watershed.WQ8 Minimize the introduction of pathogens to the water supply.WQ9 Once the Sunol Valley quarries have been reclaimed as reservoirs, maintain water quality in thereservoirs so that the water remains treatable by the Sunol Valley WTP.WQ10 Minimize, and where possible prohibit, the construction of new roads and trails.WQ11 Where new roads or trails are required, locate and design them to follow natural topography.WQ12 Minimize and where possible restrict to low vulnerability areas, construction of new roads or accesseasements through primary Watershed lands that serve new development not on SFPUC lands.WQ13 Minimize and where possible restrict new easements and rights-of-way through primary Watershedlands to areas of low vulnerability.WQ14 Optimize the existing road system such that there are no more roads than necessary for operationsand maintenance purposes.WQ15 In the primary Watershed, minimize, and where possible prohibit, land uses and activities that havethe potential to cause erosion, sediment generation, and stormwater runoff.WQ16 Where suitable, use sedimentation basins to control the effects of erosion and sediment transport.WQ17 Minimize and where possible prohibit the creation of impervious surfaces in primary Watershed.WQ18 Minimize vehicle-related contaminants in runoff from roads, parking lots, facilities, etc.WQ19 Minimize and where possible prohibit the construction of new on-site waste treatment systems toserve facilities or other new developments on Watershed lands.WQ20 Coordinate water quality concerns with fire management activities to prevent erosion.WQ21 Foster interagency agreements with adjacent jurisdictions to limit new construction on non-SFPUClands within the hydrologic Watershed to minimize adverse effects to water quality.WQ22 Actively seek acquisition or purchase conservation easements over lands within the hydrologicWatershed not in SFPUC ownership that are critical to water quality and supply.WQ23 Prohibit the sale or exchange of SFPUC lands within the primary Watershed that are critical towater quality, supply, and SFPUC operations.WQ24 Actively participate in local and regional government planning processes to keep abreast of newprojects which may affect SFPUC lands and water quality.WQ25 Wherever possible, preserve and protect stream channels and banks in the primary Watershed toprotect water quality by maintaining or improving channel stability and reducing bank erosion.WQ26 Prohibit unauthorized fill or excavation activities on wetlands, riparian zones, etc.NOP 96.223E: Alameda Watershed Management Plan III.D-10 ESA / 930385January 2001
