The purpose of this chapter is to regulate land disturbance activities, including the clearing and removal of vegetation, excavation, grading, filling and other earthwork such as cuts and fills within the City of Lake Stevens to protect public health, safety and welfare by requiring the following elements:
(a) 
Encouraging holistic site planning to reduce negative impacts to the community and the environment;
(b) 
Preserving vegetation and where appropriate requiring commensurate replanting;
(c) 
Requiring the implementation of best management practices (BMPs) during land disturbing activities;
(d) 
Minimizing adverse stormwater impacts related to land disturbance per the requirements of the 2019 Department of Ecology Stormwater Manual for Western Washington or as amended;
(e) 
Assuming regulatory authority for Class IV Forest Practices as defined by Chapter 76.09 RCW;
(f) 
Establishing administrative procedures to issue permits, approve plans and inspect land disturbance activities; and
(g) 
Reducing the amount of time between land disturbance and the beginning of actual site construction.
Land disturbance activities within or near a critical area or within the shoreline jurisdiction must be consistent with the provisions of Chapter 14.88 and the Lake Stevens Shoreline Master Program, as applicable.
