<br /> <br />21 <br /> <br /> <br />17A.02.155 Clearing. <br />“Clearing” means significant vegetation removal including the removal or alteration of trees, shrubs, <br />and/or ground cover by grading, cutting, burning, chemical means, or other activity that causes <br />significant ecological impacts to functions provided by such vegetation. The removal of invasive or <br />noxious weeds does not constitute significant vegetation removal. Tree pruning, not including tree <br />topping, where it does not affect ecological functions, does not constitute significant vegetation <br />removal. <br /> <br />17A.02.160 Critical Aquifer Recharge Areas. <br />“Critical aquifer recharge areas" are areas with a critical recharging effect on aquifers used for <br />potable water, including areas where an aquifer that is a source of drinking water is vulnerable to <br />contamination that would affect the potability of the water, or is susceptible to reduced recharge. <br />17A.02.170 Critical Areas. <br />“Critical areas" include the following areas and ecosystems: (a) wetlands; (b)critical aquifer recharge <br />areas; (c) fish and wildlife habitat conservation areas; (d) frequently flooded areas; and (e) geologically <br />hazardous areas. <br /> <br />17A.02.200 Cumulative Impacts <br />“Cumulative Impacts” or “cumulative effects” means the combined, incremental effects of human <br />activity on ecological or critical areas functions and values. Cumulative impacts result when the <br />effects of an action are added to or interact with other effects in a particular place and within a <br />particular time. It is the combination of these effects, and any resulting environmental degradation, <br />that should be the focus of cumulative impact analysis and changes to policies and permitting <br />decisions. <br /> <br />17A.02.210 Dam. <br />"Dam" means a barrier or controlling and appurtenant works across a stream or river that does or <br />can confine, impound or regulate flow, or raise water levels for purposes such as flood or irrigation <br />water storage, erosion control, power generation, or collection of sediment or debris. <br /> <br />17A.02.220 Development. <br />“Development” means any activity upon the land consisting of construction or alteration of structures, <br />earth movement, dredging, dumping, grading, filling, mining, removal of any sand, gravel, or <br />minerals, driving of piles, drilling operations, bulkheading, clearing of vegetation, or other land <br />disturbance. Development includes the storage or use of equipment or materials inconsistent with <br />the existing use. Development also includes approvals issued by the County that binds land to <br />specific patterns of use, including but not limited to, subdivisions, short subdivisions, zone changes, <br />conditional use permits, and binding site plans. Development activity does not include the following <br />activities: <br /> <br />1. Interior building improvements. <br />2. Exterior structure maintenance activities, including painting and <br />roofing. <br />3. Routine landscape maintenance of established, ornamental <br />landscaping, such as lawn mowing, pruning, and weeding. <br />4. Maintenance of the following legally existing facilities that does not <br />expand the affected area: septic tanks (routine cleaning); wells; <br />individual utility service connections; and individual cemetery plots in <br />established and approved cemeteries. <br />
