19.76.010 Policy.
A. Purpose. Washington State law mandates that stormwater discharge resulting from development activities and pollution-generating activities be controlled and treated to provide available and reasonable methods of erosion control, flood control, habitat protection, and water quality treatment. The City of Anacortes has adopted the requirements of this chapter for both temporary and long-term stormwater management. The purpose of this chapter is to set out the authority, regulatory requirements, submittal requirements, and procedures for stormwater drainage design, review, approval, construction, maintenance, and management.
B. Goals of Low Impact Development (LID). LID is the preferred and commonly used approach to site development. LID is intended to minimize impervious surfaces, native vegetation loss, and stormwater runoff in all types of development situations. (City’s NPDES Permit S5.C4.f.i) This chapter accomplishes the following goals:
1. Manage stormwater through a land development strategy that emphasizes conservation and use of on-site natural features integrated with engineered, small-scale hydrologic controls to mimic predevelopment hydrologic conditions;
2. Encourage creative and coordinated site planning, the conservation of natural conditions and features, the use of appropriate technologies and techniques, and the efficient layout of streets, utility networks and other public improvements;
3. Reduce impervious surfaces; and
4. Preserve or restore native vegetation. (Ord. 2991 § 1 (Att. A), 2016)
