Newport Beach 应对海滩严重流沙：拟自 Santa Ana River 运沙约10万立方码补滩 市议会听取方案
Newport Beach——位于加州橙县的Newport Beach市，在经历风暴潮与「热带风暴 Rachel」造成的大面积海岸洪水后，Newport Beach 市议会10月13日听取了市政工作人员关于海滩严重流沙的详细简报与紧急补沙方案。公共工程主任 Dave Webb 表示，市府已就一项用卡车运沙的方案询得报价：拟从 Santa Ana River 运送约10万立方码沙料，补到海滩防波堤石区（groin fields）一带最脆弱的滩段，相关合同预计将提交市议会审议授标。
工作人员在简报中回顾了近期的历史性沙量流失与紧急筑沙堤作业，并指出更大规模的水力疏浚补沙工程可能因许可与资金问题而延后。市府同时提醒居民备好沙袋，为10月下旬至12月间的「国王潮」（king tides）高水位期作准备——此前的高潮位已多次造成 Balboa Peninsula 一带街道进水。
本月初，前飓风 Rachel 的涌浪叠加异常高潮位，冲越了 Wedge 一带约20英尺高的沙堤，Balboa Peninsula 约15至20个街区被淹，市政府一度宣布本地紧急状态并关闭部分海滩与码头。市议员 Joe Stapleton 当时表示，这是他居住半岛20年来所见最严重的一次。
市议会此次听取的运沙方案属于近程应急措施，目标是在冬季高潮位与风暴季到来之前，先为最脆弱的滩段补上沙量；更大规模的补沙工程仍有待许可与资金落实。（GSM 据 Newport Beach 市议会会议信息）
Newport Beach Weighs Trucking About 100,000 Cubic Yards of Sand From the Santa Ana River to Rebuild Eroded Beaches
NEWPORT BEACH — Newport Beach is a city in Orange County, California. After storm surf and Tropical Storm Rachel drove widespread coastal flooding, the Newport Beach City Council heard a detailed staff briefing on October 13 on severe sand loss along the oceanfront and an emergency plan to move material into the most vulnerable stretches of beach. Public Works Director Dave Webb said the city has a bid to truck about 100,000 cubic yards of sand from the Santa Ana River to the groin fields, and expected to bring the contract to the council for award.
Staff described historic sand loss and the emergency berming already carried out, and warned that a larger hydraulic dredging program could be delayed by permitting and funding. Officials urged residents to use sandbags and prepare for king tides from late October through December, after recent high water repeatedly flooded streets on the Balboa Peninsula.
Earlier this month, swell from former Hurricane Rachel combined with unusually high tides to overtop roughly 20-foot sand berms near the Wedge, flooding an estimated 15 to 20 blocks of the Balboa Peninsula. The city declared a local emergency and closed some beaches and piers. Councilman Joe Stapleton called it the worst he had seen in 20 years on the Peninsula.
The trucking plan is a near-term measure to rebuild sand on the most exposed beach segments before the winter high tides and storm season, while larger-scale replenishment awaits permits and funding. (GSM, based on Newport Beach City Council meeting information)
