ISM Potential Coastal Engineering Structure Parcels Pursuant to the Wetlands Protection Act (view)

The four adjacent Outer Cape communities of Eastham, Truro, Provincetown, and Wellfleet have built an intermunicipal partnership to pursue a regional approach to shoreline management. This partnership promotes short- and long-term science-based decisions that will maximize the effectiveness and efficiency of community responses to the increased threat of coastal hazards. This layer is a product of that partnership, the Intermunicipal Shoreline Management Project, a project first initiated in 2019 with funding from CZM"s Coastal Resilience Grant Program. The Wetlands Protection Act 310 CMR 10.30 states when a coastal bank is determined to be significant to storm damage prevention or flood control because it supplies sediment to coastal beaches, dunes or barrier beaches then no new bulkhead, revetment, seawall, groin or other coastal engineering structure is permitted. An exception applies when the coastal engineering structure is required to prevent storm damage to buildings constructed before the effective date of August 10, 1978. This dataset shows the parcel location of buildings built before 1978 with no existing coastal engineering structure. Parcel features were extracted from MassGIS Data: Standardized Assessors" Parcels (2019). Digital parcel standard level 3 products were used for M086, M242, M300 and M318. Last update: 6/04/2026伊斯塔姆（Eastham）、特鲁罗（Truro）、普罗温斯敦（Provincetown）与韦尔弗利特（Wellfleet）四座毗邻的外开普社区，已组建跨市政伙伴关系，以推行海岸线管理的区域化方案。该伙伴关系致力于推动基于科学的短期与长期决策，最大化社区应对日益加剧的海岸灾害威胁时的响应效率与成效。本图层即为该伙伴关系的成果——跨市政海岸线管理项目（Intermunicipal Shoreline Management Project）的产物，该项目于2019年首次启动，资金来源于CZM海岸韧性资助计划。 《湿地保护法（Wetlands Protection Act）》310 CMR 10.30条款规定：若某海岸岸堤因向沿海海滩、沙丘或屏障海滩输送泥沙，被认定为对风暴灾害防护或防洪具有重要意义，则不得新建驳岸、护坡、海堤、丁坝或其他海岸工程结构。但若该海岸工程结构用于防护1978年8月10日生效日之前建成的建筑物免受风暴破坏，则可例外适用。本数据集标注了1978年前建成且未配备现有海岸工程结构的建筑物宗地位置。 宗地要素提取自马萨诸塞州地理信息系统（MassGIS）数据：《标准化评估宗地（2019）》（Standardized Assessors' Parcels (2019)）。M086、M242、M300及M318区域采用数字宗地标准三级产品。最后更新日期：2026年6月4日。
