OHSEM Stream Reno Data - Parcel Access Poly

The Stream Restoration Parcel Access Polygons layer was developed to support the suitability analysis for stream restoration projects. The polygons were derived from MCAD tax parcels and manually modified to account for: Permanent easements and rights-of-way (ROW) for electric and oil & gas pipelines Gaps filled to account for road and railroad transportation ROWs Newly created parcels to ensure complete coverage for potential project access Important Notes: These polygons are not official easements or ROWs and should not be used as legal property boundaries They are intended to model potential access points to stream restoration project areas, with a preference for existing transportation ROWs where feasible These parcels were used to create the classified parcel access polygons which then informed the final suitability analysis Intended Users: Contractors, consultants, and planning staff working on stream restoration projects GIS analysts evaluating access and planning construction logistics Access / Sharing: Publicly available for download Read-only access; editing is restricted Update Frequency: Updated as new parcels or ROW modifications are identified and incorporated into access planning Data Sources: MCAD Tax Parcels Road, rail, and utility ROW information Montgomery County IT-GIS derived modifications河流修复地块准入多边形图层（Stream Restoration Parcel Access Polygons layer）旨在支撑河流修复项目的适宜性分析工作。该多边形数据源自MCAD计税地块，并经手动修正以覆盖以下场景：电力、石油及天然气管道的永久地役权与通行权（rights-of-way，简称ROW）；填补道路、铁路运输通行权相关的空白区域；新增地块以确保潜在项目准入的完整覆盖范围。 重要说明： 本多边形数据并非官方地役权或通行权凭证，不得作为合法产权边界使用；其旨在模拟河流修复项目区域的潜在准入点位，可行情况下优先采用现有运输通行权；此类地块被用于生成分类地块准入多边形，进而为最终适宜性分析提供决策依据。 目标用户： 开展河流修复项目的承包商、顾问及规划人员；评估准入情况并规划施工物流的GIS分析师。 获取与共享： 可公开下载获取；仅支持只读访问，编辑功能受限。 更新频率： 当识别到新地块或通行权变更并纳入准入规划时，将及时更新。 数据来源： MCAD计税地块；道路、铁路及公用设施通行权信息；蒙哥马利县IT-GIS生成的修正数据。
