PROPERTY WHERE WORK IS OCCURRING ADDRESS: 4410 San Juan Ave, Anacortes WA 98221 PARCEL NUMBER(S) P81763 2. GENERAL INFORMATION Most development within the City of Anacortes that involves disruption of soils, or construction of buildings, streets, parking lots, etc. requires a Stormwater review. Stormwater review requirements are based on either the amount of soil to be disturbed (grading, vegetation removal), or the amount of hard surface that is created or replaced on a site (building footprint, concrete, asphalt or gravel parking, sidewalk, etc.) This form is largely targeted for small projects and single family residences. For larger projects and more information please refer to the Anacortes Municipal Code (Chapter 19.76 Stormwater Management) and the latest Washington State Department of Ecology Stormwater Management Manual for Western Washington (Ecology Manual). 3. HARD SURFACE AREA CALCULATION Please calculate your project's hard surface amount; guidance is provided on the next page of this document. Use your project's total hard surface calculation to follow the flow chart(s) in this packet and determine the level of stormwater management required for you project. When determining your permit level or if stormwater thresholds are met or exceeded the entire project must be considered. A project is that portion of a property, properties, or right of way subject to land disturbing activities, new hard surfaces and replaced hard surfaces. The hard surface on your property will determine the storm water utility fees and the stormwater general facility charge. All new or replaced hard surfaces should be accounted for. Below are excerpts from the Anacortes Municipal Code and Ecology Manual that may assist you in preparing this information. "Hard surface area" means an impervious surface, a permeable pavement, or a vegetated roof. "Impervious surface" means a non -vegetated surface area which either prevents or retards the entry of water into the soil mantle asunder natural conditions prior to development. A non -vegetated surface area which causes water to runoff the surface in greater quantities or at an increased rate of flow from the flow present under natural conditions prior to development. "Replaced impervious surface" means, for structures, the removal and replacement of impervious surfaces down to the foundation. for other impervious surfaces, the removal down to bare soil or base course and replacement.
