The achievement of standards, employment of methods and techniques required by this chapter shall be applicable in the following circumstances:
A. New Subdivisions: Development of every new subdivision of land within the jurisdiction of the City.
B. Commercial And Industrial Sites: All commercial and industrial site development for which grading, site development, construction or building permits may be required pursuant to the land use regulations of the City.
C. Public Projects: 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 which could or will affect stormwater drainage patterns within the jurisdiction. Except as necessary to maintain the continuity of existing stormwater handling systems, all new construction as outlined in this section, shall employ the methods for stormwater management required by this chapter and shall otherwise be designed to minimize adverse impacts upon surface and ground water quality.
D. Land Disturbing Activities: Every building or land development permit where land disturbing activity is to occur on any part of the sites with a slope greater than fifteen percent (15%) or on sites less than five hundred feet (500') from environmentally sensitive areas such as wellhead protection areas and saturated aquifer recharge areas 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 feature which can be determined from USGS 7.5 minute quadrangle topographic maps, or as recognized by any State or Federal agency. 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 for individual building sites may still be required to be submitted to the City, who may require mitigating conditions upon the approval for the related permit activity. A building permit may be issued for minor additions to existing improvements without the preparation of a stormwater management plan if the City determines that the requirements of this chapter can be met by existing site conditions.
