e. Require on -site contracts and development standards, as practical, to reduce off -site impacts from stormwater runoff, f. Use natural and simple mechanical treatment systems to provide treatment for potentially contaminated runoff waters; g. Reduce street- related water quality and quantity problems; h. Regulate use and require containment and /or pretreatment of toxic substances; i. Include containment measures in site review standards to minimize the effects of chemical and petroleum spills; and j. Consider impacts to ground water quality in the deign and location of dry well. G.14 Implement changes to stormwater facilities and managementpractices to reduce the presence of pollutants regulated under the Clean Water Act and to address the requirements of the Endangered Species Act. G.15 Consider wellhead protection areas and surface water supplies when planning stormwater facilities. G.16 Manage or enhance waterways and open stormwater systems to reduce water quality impacts from runoff to improve stormwater conveyance. G.17 Include measures in local land development regulations that minimize the amount of impervious surface in new development in a manner that reduces stormwater pollution, reduces the negative affects from increases in runoff, and is compatible with Metro Plan policies. Refinement Plan Policies — The above - described stormwater development standards are consistent with following refinement plan policies: Comprehensive Stormwater Management Plan Policies: 1.1 Incorporate the beneficial functions (flood control, stormwater conveyance, water quality treatment) of natural resources into the city's storm drainage system. 1.2 Maintain flood control, drainage, and water quality treatment capacities along the city's stormwater conveyance corridors while protecting and enhancing the health, diversity and continuity for wildlife habitat, native vegetation, and endangered species. 1.6 Balance the operational needs of managing natural resource and wildlife habitat areas against any associated nuisance conditions that may result. 1.8 Evaluate the effectiveness and appropriateness of a variety of surface water management facilities for meeting the multiple objectives of this plan. 2.1 Meet or exceed federal flood hazard requirements.
