ABSTRACT: Municipalities and Stormwater Authorities confront significant challenges in getting their arms around their goals and workload. They must cover the update of asset inventories, integration of business and technical information, planning and managing improvements and maintenance, and communication with multiple partners, funding sources and regulators. Key for alignment of the diverse workload is having the base information set in a framework allowing its use in all workflows. Tools drawing data from such information framework enable the alignment. Incorporation of existing and emerging Standards and Best Practices for water related data provides the framework.
Bringing experiences in stormwater system mapping projects large and small, from Washington DC to Kingston, NY, the presentation shows how standards for hydrography, stormwater, and hydrologic and hydraulic modeling are the framework that allows tying the base information to workflows, communication and funding activities. Reviewed best practices include: LiDAR based updates; road culvert and stormwater sewer system inventory and characterization; integration with surface runoff, Natural Resource Inventory and Green Infrastructure. Mapping and modeling standards covered include NAACC for culvert inventory, high resolution NHDPlus for surface and stormwater system integration, StreamStats and the National Water Model for H&H modeling, and other emerging stormwater system mapping standards.
