Levee

Not an exhaustive representation of levees within the SJRWMD. UPDATE NOTES: In 2024.04, geometry and field attribute, domain schema changes and additions were completed by OIT-GIS team per Operations & Maintenance staff, who are the account content owner. The geometry request was to merge levee segments per each levee name. In 2017, this database was updated to include 3 levee segments that have been downloaded from the 2012 NLD (National Levees Database):L-212 (5.42 miles): This portion divides the Ocklawaha River from Ocklawaha Prairie Restoration Area. Has been turned over to SJRWMD for maintenance. Ocklawaha River Basin C231 (7.23 miles): This portion divides the Ocklawaha River from the Sunnyhill Restoration Area. Has been turned over to SJRWMD for maintenance. L-78: This is the tail end of a federal levee in USJRB.本数据集并非圣约翰河水资源管理区（St. Johns River Water Management District, SJRWMD）范围内堤防的完整展示。 更新说明：2024年4月，信息技术办公室地理信息系统团队（Office of Information Technology-GIS, OIT-GIS）依照作为数据内容所有者的运维人员要求，完成了几何数据、字段属性、领域模式的修改与新增工作。本次几何数据更新要求按堤防名称合并各分段堤防。 2017年，本数据库完成更新，新增3段取自2012年国家堤防数据库（National Levees Database, NLD）的堤防分段： 1. L-212（5.42英里）：该段堤防分隔奥克拉华哈河与奥克拉华哈草原修复区，已移交圣约翰河水资源管理区负责维护。 2. 奥克拉华哈河流域C231（7.23英里）：该段堤防分隔奥克拉华哈河与桑尼希尔修复区，已移交圣约翰河水资源管理区负责维护。 3. L-78：该段为美国圣约翰河盆地（U.S. St. Johns River Basin, USJRB）内联邦堤防的末端段落。
