 "snippet": "This project aimed to develop a consistent and comprehensive spatial database of tidal restriction features (e.g., culverts, tide gates, levees, and dikes), and current and potential tidal wetland habitat extents for Puget Sound\u2019s major large river deltas. Although numerous spatial datasets for tidal restriction and wetland habitat currently exist, these have not been synthesized into a consistent regional dataset. In addition, many datasets are incomplete or have become outdated. Regional datasets were compiled into a consistent spatial database and remote sensing was used to update and correct regional data, digitize missing features, and classify feature types and potential connectivity impacts. The resulting spatial database was used to delineate current and potential tidal wetland habitat extents and integrate tidal restriction information. The products of this project are directly supporting salmon recovery planning and evaluation in the Puget Sound region (e.g., ESRP\u2019s River Deltas Learning Objectives, PSP\u2019s Estuaries Vital Sign and Common Chinook Indicators, NOAA\u2019s Salmon Habitat Status and Trends Monitoring Program, and WDFW\u2019s intertidal fish passage assessments) by providing spatial data that can be used to identify and evaluate restoration opportunities, inform development and evaluation of recovery targets at regional and system scales, and identify data gaps to guide future research needs.",
 "description": "The Tidal Wetland network represents the current and potential tidal wetland habitat network as polygons and their tidal connectivity determined using the Tidal Restriction network, remotely sensed aerial imagery, SHSTMP tidal wetland habitat extent and feature polygons (NOAA 2011; 2016), and Pacific Marine and Estuarine Fish Habitat Partnership (PMEP) tidal exceedance polygons (PMEP 2018). The maps of current and potential tidal wetland habitat were updated using the spatial database of the tidal restriction network developed in this project, SHSTMP tidal wetland habitat extent, feature polygons, and overwater structures (NOAA 2011; 2016; 2019), and Pacific Marine and Estuarine Fish Habitat Partnership (PMEP) tidal exceedance polygons (PMEP 2018). Tidal restrictions were buffered and used to segment PMEP wetland polygons into individual polygons, to associate tidal restriction features, feature types, and tidal connectivity ratings to polygons of tidal wetland habitat. Tidal wetland connectivity ratings were determined using the Tidal Restriction network and the SHSTMP tidal wetland habitat features to assess pathways of tidal movement and were assigned as Completely Restricted, Significantly Restricted, Partially Restricted, Unrestricted, or Unknown. Tidal wetlands were classified by both their tidal feature connectivity and landscape connectivity with certainty ratings. The feature tidal connectivity classified the tidal connectivity of the feature based on the tidal connectivity to that feature given the immediately downstream tidal restriction features. Feature tidal connectivity was determined by the downstream feature allowing tidal connectivity regardless of upstream or landward tidal restrictions connectivity restrictions. The landscape tidal connectivity classified the tidal connectivity of the wetland feature based on its connectivity to the delta as a whole. The landscape tidal connectivity of a feature was determined by the connectivity rating of the landscape wetlands and the downstream tidal restriction features.",
