The riparian area is defined as the area adjacent to a stream that provides the following functions: shade, sediment, nutrient or chemical regulation, streambank stability, and input of large woody debris or organic matter.See the final rule (64 FR 24049) for descriptions of areas excluded from this critical habitat designation. Excluded Indian lands were not clipped out of the data.

United States Geological Survey (USGS) 20180208 map The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. Local resolution NHD was developed where partners and data existed. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Names were assigned to most features from the Geographic Names Information System. None National Hydrogaphy Dataset The lines in this dataset were extracted from a 2018 version of the high resolution National Hydrography Dataset (NHDFlowline feature class). The lines were split at specific locations to represent the upstream ends of critical habitat; other vertices were not altered. Data creation process 2019. COCCC_CH.shp Central California Coast (CCC) coho data were developed as part of an effort to interpret and depict several salmonid critical habitat designations completed in the 1990s that relied on text-based descriptions but lacked GIS data. Critical habitat areas were identified based on the following: - The regulatory definition of ESA critical habitat for this ESU found at 50 CFR 226.210 (a) and the supporting final rule (64 FR 24061, May 5, 1999); - U.S. Geological Survey (USGS) high resolution National Hydrography Dataset (NHD) - downloaded February 2018; - Intrinsic Potential (IP) GIS data from a juvenile coho rearing model developed by the Southwest Fisheries Science Center (SWFSC); - National Elevation Data and Digital Topographic Maps; - California Fish Passage Assessment Database [ds69, published 2019-03-05] and Coho Distribution [ds326, published 2016-06-22] from the California Department of Fish and Wildlife (CDFW); - The professional judgment of biologists from the NMFS California Coastal Office, Protected Resources Division, and SWFSC; and - Maps and documentation in these references: Spence, B.C., Harris, S.L., Jones, W.E., Goslin, M.N., Agrawal, A., and E.

Spatial analysis steps to produce data. 1) Clipped the NHD to the text description from the critical habitat designation 2) Partitioned the NHD into 100 meter segments 3) Calculated the gradient of each 100 meter segment using a 10 meter USGS digital elevation model (DEM) 4) Used the NHD's flow direction and a geometric network to analyze gradient, removed segments upstream of 7% gradients (reference: Agrawal et. al. 2005 - Figure 1 gradient suitability curve for coho) 5) Retained segments downstream of 7% gradients that were too small (<= 20 meters) to rely on the gradient value (i.e., 1 to 2 pixels in the DEM) or were artificial paths (NHD FCode 55800) to maintain network connectivity 6) Retained segments that overlapped with CDFW coho distribution data (field observations) and SWFSC intrinsic potential coho data (model) with the 21.5 deg C temperature mask applied (Agrawal et. al. 2005) 7) Removed segments upstream from total natural barriers, total anthropogenic barriers, and partial barriers that were specifically identified as blocking upstream adult coho migration 8) Removed segments identified by NMFS biologists as not being accessible to or suitable habitat for coho. The following tribal lands were excluded from the Central California Coast coho critical habitat designation, but were not clipped out of the spatial data: Cloverdale Rancheria, Coyote Valley Rancheria, Dry Creek Rancheria, Guidiville Rancheria, Hopland Rancheria, Lytton Rancheria, Manchester/Point Arena Rancheria, Pinoleville Rancheria, and Stewarts Point Rancheria. **IMPORTANT NOTE** Critical habitat was designated to include "all river reaches accessible in 1999" to CCC coho salmon from Punta Gorda in northern California south to the San Lorenzo River in central California, including Arroyo Corte Madera Del Presidio and Corte Madera Creek, tributaries to San Francisco Bay. These spatial data are NMFS' best estimate of "all river reaches accessible in 2019". We mapped 2019 accessibility because it was not feasible to retroactively map reaches that were accessible in 1999. 20191010 Protected Resources Division, West Coast Region, National Marine Fisheries Service Shanna Dunn GIS Analyst unknown
