 "description": "The Nearshore Geospatial Framework provides a connection between data based on the ShoreZone shoreline (including coastal data from the ESRP Beach Strategies project) and nearby inland and aquatic spatial data. The purpose of this framework is to enable Chinook salmon restoration and protection. The Nearshore Geospatial Framework consists of polygons with one edge coincident with the ShoreZone shoreline, such that GIS users can easily link coastal data with upland and aquatic data. These polygons are constructed from Beach Strategies shoretypes and net shore-drift cells. In the Nearshore Geospatial Framework, \"net shore-drift cells\u201d include each contiguous stretch of left-to-right or right-to-left net shore-drift, as well as areas of no appreciable drift.The Nearshore Geospatial Framework Basins dataset provides a set of zones representing upland areas that may be hydrologically connected to net shore-drift cells. Hydrological basins were constructed using data from the PSLC 2014 Supermosaic DEM as the input for a hydrological flow model with a spatial resolution of 12 feet. Basins with a total area less than 0.05 square miles were merged into larger single basins. The outlines of these hydrological basins were used to burn borders into a raster cost surface. Then the onshore area closest to each net shore-drift cell was identified using a cost-allocation technique. Allocation was constrained to areas within hydrological basin boundaries and no more than approximately 65,000 feet inland. Then gaps were filled, the data were vectorized, and the results were clipped to land as defined by the ShoreZone shoreline. Topological rules were used to ensure that polygons did not overlap each other and that the coastal border of all polygons coincided with the ShoreZone shoreline line feature. All work was completed in the NAD_1983_HARN_StatePlane_Washington_South_FIPS_4602_Feet projected coordinate system.Resulting polygons show approximate drainage areas corresponding to each net shore-drift cell. Note that parts of Clallam County were missing from the source DEM and not processed. Unlike other NGF products, a similar shoretype version was not constructed because minimum shoretype segment length is impractically close to DEM resolution.This project was made possible with funding and support from the Puget Sound Partnership.",
