Policv I Solid Waste Promote safe environmentally sound means of solid waste disposal for the community 1 Proceeds of recycling are a resource and should be used to benefit the community to the extent feasible 2 Investigate means to create a market for recycled goods PUBLIC SAFETY 54 INCLUDES AMENDMENTS THROUGH GPA 9401 POWA Y COMPREHENSIVE PLAN GENERAL PLAN 3 Implement a curbside recycling program in all residential neighborhoods 4 Promote the use of all plant material waste for compost or mulch 5 Promote the recycling of construction refuse and white waste water heaters washing machines etcl 6 Investigate ways to encourage businesses to recycle their waste GOAL VIII IT IS THE GOAL OF THE CITY OF POWAY TO MINIMIZE INJURIES LOSS OF LIFE AND PROPERTY DAMAGE RESULTING FROM NATURAL AND MAN MADE HAZARDS Policv A Information and Services The City should encourage the development and implementation of hazard prevention programs designed to provide adequate information and services to the community Strateoies 1 Increase public awareness of dangers associated with natural hazards and of strategies that can be adopted to deal with them 2 Assure that all development applications are reviewed by persons qualified to identify potential natural hazard problems and that appropriate conditions be attached to allowed developments so as to mitigate potential damage 3 Actively encourage the generation of ideas plans and programs to achieve a state of community self reliance Policv B Geoloaic Hazards The community should be protected against the hazards associated with geologic formations particularly landslides through proper land use policies and mitigation StrateQies 1 Compare all development applications with the GIMS Mapping System to determine if significant geologic hazards exist 2 Investigations performed by a qualified engineering geologist and soil engineer shall be required for all development review applications For land development in the Friars Formation areas a detailed slope stability analysis is also required INCLUDES AMENDMENTS THROUGH GPA 9401 PUBLIC SAFETY 55 POWA Y COMPREHENSIVE PLAN GENERAL PLAN 3 Include as conditions of approval the recommendations of the engineering geologist for geologic hazard mitigation and the soils engineer for soil related issues 4 Development within unstable slope and landslide areas will be prohibited unless adequate measures are taken to protect against slippage 5 Establish and maintain proper soil management techniques to reduce the adverse effects of soil related problems such as shrink swell behavior erosion run off potential and septic tank failure Policy C Seismic Safety Seismic hazards should be controlled to a level of acceptable risk through the identification and recognition of potentially hazardous conditions and areas Strateaies 1 Take all appropriate actions to identify and mitigate seismic hazards such as groundshaking ground rupture landslides liquefaction and structural hazards 2 The GIMS Mapping System and the Seismic Matrix shall be used to determine if the probability of a seismic hazard exists 3 Where it has been determined that there is the probability of a seismic hazard an investigation by a qualified engineering geologist shall be required 4 Regularly inform community residents of the potential seismic hazards that can exist and the best methods of reducing injury property damage or loss of life in the home or business establishment Policy D Flood Hazards The public should be protected against potential loss of life and property through regular dam and creek maintenance proper flood hazard management policies and future capital improvements Strateaies Lake poway Dam 1 Lake Poway Dam shall receive regular inspections of the embankment spillway and inleUoutlet facilities to ensure safe operation 2 Lake poway shall be kept at or below the designed high water level to reduce the risk of spilling PUBLIC SAFETY 56 INCLUDES AMENDMENTS THROUGH GPA 9401 POWA Y COMPREHENSIVE PLAN GENERAL PLAN Natural Watercourses 3 Natural watercourses shall be maintained as the primary flood control channels Where feasible the natural creekside environment shall be preserved 4 Maintain a program to ensure that the floodways are kept free and clear at all times Costs associated with creek maintenance shall be borne by the property owner or the holder of open space easement rights 5 Upstream detention basins shall be constructed on Rattlesnake Creek and the north and south branches of poway Creek as outlined in the Floodwater Detention Basin Survey published in August 1981 in order to mitigate flood hazards while retaining the natural character of the major creeks and channels Watershed Areas 6 Watershed areas in the eastern poway mountains should be preserved to maintain the health safety and welfare of residents living adjacent to the City s major creeks in the poway Valley Financing 7 The City shall explore and adopt appropriate legislation to finance the acquisition and construction of the detention basins including but not limited to developer financing bonds and assessment areas drawn upon drainage area boundaries 8 The cost of improvements to the City flood and drainage control system made necessary by new development shall be borne by the developer INCLUDES AMENDMENTS THROUGH GPA 9401 PUBLIC SAFETY
