Dowusn39eam of 31 Undersized Culvert 3 W4 ACTIVITY FINDING YOUR OWN SOLUTIONS Issues that need to be addressed Water supplies are limited yet no local consensus exists on priorities for beneficial uses of the water supply All water dischargers need to com ly with state and federal water quality standards including regulations for point an nonpoint pollution sources The watershed contains an accumulation of toxic chemicals and the control and mitigation of pollution in the watershed needs to be effective Erosion land loss and sedimentation have been accelerated by agriculture and urbanization Potential conflicts exist between wetland conservation planned urban activities and public facilities Potential specieshabitat impacts are unquantifiable because adequate data does not eXIs Upland habitat loss may result in species endangerment thereby necessitating future regulations with potentially adverse economic consequences No coordinated strategy exists to set aside public lands and a recreational trail system for use by future generations Environmental regulations and the associated responses should be coordinated and streamlined and the WMP should take a holistic rather than a piecemeal approach All stakeholders want to maintain and if possible enhance the quality of life in the Calleguas Creek Watershed Last Notes I There are many tools and knowledge available to obtain a good solution I Successful projects is backed by political will and public support I Good solutions are those that are adaptive Easier said then done I Good solutions are those
