ECA - Peat Settlement Prone Area

Peat-settlement-prone areas (sites containing peat and organic soils that may settle when the area is developed or the water table is lowered). Peat settlement-prone areas. Peat settlement-prone areas consist of Category I and Category II peat settlement-prone areas that are delineated on Maps A1 through A26, Peat Settlement-prone Area Boundaries Maps, codified at the end of this Chapter 25.09. This parcel-specific delineation is based on the location of the relevant bog or bogs identified in City of Seattle Identified Bogs (Troost 2007) plus a buffer of 50 feet for Category I peat settlement-prone areas or a buffer of 25 feet for Category II peat settlement-prone areas. On parcels larger than 50,000 square feet, the Director may consider a parcel-specific delineation, provided by the applicant, of the peat settlement-prone area boundary on a parcel. Where a parcel-specific delineation conflicts with the Peat Settlement-prone Area Boundaries Maps, the parcel-specific delineation shall apply. For more information about the definition of peat settlement prone areas, see Seattle Municipal Code section 25.09.012, Environmentally Critical Areas (ECA) definitions. Updated as needed.易发生泥炭沉降区域（Peat-settlement-prone areas）指区域内含有泥炭及有机土壤，在地块开发或地下水位下降时可能发生沉降的区域。该区域分为一类和二类易发生泥炭沉降区域，其边界已在本第25.09章末尾编纂的《A1至A26号易发生泥炭沉降区域边界地图（Peat Settlement-prone Area Boundaries Maps）》中划定。本次地块专属边界划定以《西雅图市已识别沼泽名录（Troost, 2007）》中确认的一处或多处相关沼泽的位置为基础，其中一类区域需额外增设50英尺缓冲带，二类区域则增设25英尺缓冲带。对于面积超过50000平方英尺的地块，主管部门可审核申请人提交的该地块易发生泥炭沉降区域边界的专属划定方案。若地块专属划定方案与上述边界地图存在冲突，则以地块专属划定方案为准。如需了解易发生泥炭沉降区域的详细定义，请参阅《西雅图市政法典》第25.09.012节‘环境关键区域（Environmentally Critical Areas，ECA）定义’。本内容可根据需要更新。
