This chapter shall be applicable in the following circumstances:
A. Development of every new subdivision of land within the jurisdiction of the city.
B. All public projects within the jurisdiction of the city including, but not limited to, street construction or reconstruction (modification of the cross section, not to include resurfacing), park development, building development or other public works construction or development. Except as necessary to maintain the continuity of existing stormwater handling systems, all new construction as outlined in this subsection, shall employ the methods for stormwater management required by this chapter and shall otherwise be designed to minimize adverse impacts upon surface and groundwater quality; or
C. Every lot or every building permit or land development permit where land disturbing activity is to occur on any part of the site with a slope greater than fifteen percent (15%) or on sites less than five hundred feet (500') distant horizontally from, and located vertically above, any surface water in the form of a perennial or intermittent stream, river, pond, lake, wetland or similar surface water feature which can be determined from USGS seven and one-half (7.5) minute quadrangle topographic maps. Stormwater management plans may not be necessary for individual building sites if runoff from the site has been accommodated by an approved stormwater management plan for the subdivision in which the site is located. However, detailed erosion control plans may still be required. The city engineer may allow a building permit to be issued for minor additions to existing improvements without the preparation of a stormwater management plan if, in using his professional judgment, the requirements of this chapter can be met by existing site conditions.
