The purpose of this chapter is to protect property, surface water, and groundwater against significant adverse effects from excavation, filling, clearing, unstable earthworks, soil erosion, sedimentation, and stormwater runoff and to provide reasonable safety and land protections in the development and design of building sites, roads, and other service amenities. By requiring certain surface water management techniques which rely upon natural on site treatment and recycling of stormwater in applicable areas and the collection and conveyance of untreated stormwater into groundwater sources or into surface bodies of water in applicable areas. The underlying purposes to be achieved by these regulations are the protection of groundwater quality through control of stormwater prior to infiltration and protection of surface water resources from the effects of contaminants, sedimentation, and erosion.
