Stream Mapping Advisory Committee Update

Transcription

1 Stream Mapping Advisory Committee Update The North Carolina Streambed Mapping Advisory Committee (StreamMAC) is a standing committee of the Statewide Mapping Advisory Committee, which operates under the authority of the North Carolina Geographic Information Coordinating Council.

2 StreamMAC Role The North Carolina Streambed Mapping Advisory Committee is organized to establish policy and guide development of surface water mapping through the National Hydrography Dataset (NHD) and identification and delineation of watersheds and catchments through the Watershed Boundary Dataset (WBD) in North Carolina. The StreamMAC will generate recommendations based on the documented requirements of federal, state, and local government and tribal bodies.

3 StreamMAC Goals Establish designated representation with stakeholder organizations, and appoint representation with GICC committees, working groups, and related bodies. Maintain foundational materials and develop strategies to complete local resolution NHD production in North Carolina. Establish a governance framework for the technical and programmatic issues to enable technical maintenance. Establish a stewardship agreement that meets the needs of the StreamMAC membership and larger stakeholder community.

4 StreamMAC Participation NC Department of Transportation NC Department of Environment and Natural Resources NC Department of Agriculture NC Forest Service GICC Local Government Committee NC Department of Emergency Management NC Secretary of State NC Ecosystem Enhancement Program US Geological Survey US Natural Resources Conservation Service US Environmental Protection Agency US Park Service US Forest Service US Army Corps of Engineers Eastern Band of Cherokee

5 StreamMAC Workplan Develop consensus on workgroup goals and workplan for remainder of FY Designate StreamMAC representation for GICC entities and StreamMAC representation to stewardship workgroups for NHD and WBD. Develop and implement plan to document current user requirements and reassess 2004 Implementation Plan to Improve the Mapping and Digital Representation of Surface Waters in North Carolina. (ncstreams.org) Develop and implement a plan to develop a business case and updated cost model for completing local resolution NHD across North Carolina. Develop and implement a plan to establish a governance model and stewardship guidelines for NHD and WDB maintenance in North Carolina.

6 2005 Requirements Increase the quality and content of mapping, especially in upper reaches of the watersheds so that all regulated streams and water bodies are mapped and available on the Internet (through NC OneMap) Provide uniform mapping across all jurisdictions in the state resulting in an extraordinary opportunity for better decision making, closer collaborations on crossjurisdictional initiatives and better use of resources. Develop a resource that reflects current streams and lake locations in the landscape to enhance efforts to avoid wetlands in the planning of public-private facilities. Implement a plan to maintain and update the content as conditions change in the landscape thereby preserving North Carolina s investment Utilize larger, more detailed mapping scale to complement the mapping systems managed by local governments (mapping scales of 1:1,200) for local planning efforts. Improve accuracy and uniformity of stream mapping by utilizing (leveraging) the State s recent investment in statewide elevation data (using LIDAR technology), and the aerial image resources of counties and the state.
