(a) Purpose. The general purpose of this Chapter is to establish long-term, post-construction runoff management requirements that will diminish the threats to public health, safety, welfare and the aquatic environment. Specific purposes are to:
(1) Further the maintenance of safe and healthful conditions.
(2) Prevent and control the adverse effects of stormwater; prevent and control soil erosion; prevent and control water pollution; protect spawning grounds, fish and aquatic life; control building sites, placement of structures and land uses; preserve ground cover and scenic beauty; and promote sound economic growth.
(3) Control exceedance of the safe capacity of existing drainage facilities and receiving water bodies; prevent undue channel erosion; control increases in the scouring and transportation of particulate matter; and prevent conditions that endanger downstream property.
(b) Intent. It is the intent of the Village of Edgar that this Chapter regulates post-construction stormwater discharges to waters of the state. This Chapter may be applied on a site-by-site basis. The Village of Edgar recognizes, however, that the preferred method of achieving the stormwater performance standards set forth in this Chapter is through the preparation and implementation of comprehensive, systems-level stormwater management plans that cover hydrologic units, such as watersheds, on a municipal and regional scale. Such plans may prescribe regional stormwater devices, practices or systems, any of which may be designed to treat runoff from more than one (1) site prior to discharge to waters of the state. Where such plans are in conformance with the performance standards developed under Sec. 281.16, Wis. Stats., for regional stormwater management measures and have been approved by the Village of Edgar, it is the intent of this Chapter that the approved plan be used to identify post-construction management measures acceptable for the community.
