(G) Ensure the safety of Index roads and rights-of-way (F) Promote sound development policies which respect and preserve Index surface water, ground water and sediment (E) Preserve and enhance the aesthetic quality of the water (D) Preserve and enhance the suitability of waters for contact recreation, fishing, and other beneficial uses (C) Protect property owners adjacent to existing and developing lands from increased runoff rates which could cause erosion of abutting property (B) Prevent erosion and sedimentation in creeks, streams, ponds, lakes and other water bodies (A) Maintain or eliminate water quality degradation The Index town council finds that this chapter is necessary in order to: (F) Best management practices can be expected to perform as intended only when properly designed, constructed and maintained. (E) Storm water quality and quantity controls can be achieved when land is developed or redeveloped by implementing appropriate best management practices (BMPs). (D) In the future such problems and dangers will be reduced or avoided if existing properties and future developers, both private and public, provide for storm water quality and quantity controls. (C) Continuation of present storm water management practices, to the extent that they exist, will lead to water quality degradation, erosion, property damage, and endanger the health and safety of the inhabitants of Index. (B) An expanding population and increased development of land may lead to: water quality degradation through discharge of nutrients, metals, oil and grease, toxic materials, and other detrimental substances drainage and storm and surface water runoff problems within Index and safety hazards to both lives and property posed by uncontrolled water runoff on streets and highways. Storm water pollution can cause or contribute to closure of swimming beaches and other restrictions on public use of the waters within Index, Washington. Sedimentation and storm water pollution cause diversity of species to decrease and allows more tolerant (and usually less desirable) species to remain. The resulting erosion, scouring, and deposition of sediment affect the ecological balance in the stream. Land utilization and development is also known to increase both the volume and duration of peak flows. (A) Storm water pollution is a problem associated with land utilization and development and the common occurrence of potential pollutants such as fertilizers, petroleum products, pet wastes and numerous others. The Index town council hereby finds that:
