西萨克拉门托地区洪水控制机构正在迅速有效地应对2006年该州实施的更严格的洪水控制标准的挑战,这些标准必须在2025年之前达到. Together with our partners from the Department of Water Resources, Central Valley Flood Protection Board and U.S. Army corps of Engineers, WSAFCA迅速采取行动,设计和建造符合新州法律和墨西哥湾沿岸灾难后实施的新联邦堤坝标准所要求的200年防洪水平的工程.
纽约市和WSAFCA建立了监管和立法伙伴关系,以利用州和联邦政府的捐款来利用地方资金. The majority of flood projects are funded by partner agencies.
Current Projects
Southport Sacramento River Early Implementation Project
WSAFCA在8月的第一周完成了借款修复项目的牵引部分. To mitigate for the haul trucks using Gregory Avenue, WSAFCA包括了一项在运输后对巷道进行泥浆密封的项目. Before the contractor applied the slurry seal, WSAFCA worked with Public Works to repair damaged pavement, fill potholes, and seal some cracks. 在泥浆密封之前由公共工程进行的修复使成品更好. Now that the repairs and slurry seal are complete, new striping will be applied to the roadway next week.

Phase 2 - Southport Levee Improvement Project
Lead Agency: WSAFCA Project Stage: Construction completed.
Project Details: WSAFCA已经完成了南港大堤改善项目的建设,该项目涉及在西萨克拉门托市萨克拉门托河南大堤沿线建设减少洪水风险的措施. 堤防的改进包括就地修复和一个带有防渗墙的新挫折堤防建筑的组合, seepage berms, utility relocation, demolition, rock slope protection, and the use of borrow sites. Project transportation improvements included realigned roadways, new access ramps and roads, turnouts, cul-de-sacs, and maintenance corridors. 建造减少洪水风险的措施,解决渗水不足的问题, under-seepage, slope stability and geometry, erosion, encroachments, and noncompliant vegetation. WSAFCA的目标是为西萨克拉门托市实现200年来最低水平的堤坝性能. 该项目将使堤坝达到联邦和州堤坝设计标准的标准, 同时也为生态系统恢复和公众娱乐提供了机会.
