The intent of the shape is to follow the FR notice language as well as the depicted boundaries in Fact Sheet for the California No Discharge Zone Prohibiting Vessel Sewage in all California Marine Waters (https://www.epa.gov/sites/production/files/2015-10/documents/california_ndz_final_rule_factsheet.pdf) URL of Source Data: http://prd-tnm.s3-website-us-west-2.amazonaws.com/?prefix=StagedProducts/Hydrography/NHD/National/HighResolution/GDB/ Fill in gaps in bays that were not filled by the feature as constructed at this point. Inclusion of '[all enclosed bays and estuaries subject to tidal influences', as required by the FR notice. Clip off any parts of the feature, as constructed at this point, that can be represented by the following NDZ features, which are sourced from NOAA Electronic Navigational Charts. -Avalon Bay Harbor (California) sewage no-discharge zone, 1979, EPA HQ OWOW -Channel Islands Harbor (California) sewage no-discharge zone, 1979, EPA HQ OWOW -Dana Point Harbor (California) sewage no-discharge zone, 1976, EPA HQ OWOW -Mission Bay (California) sewage no-discharge zone, 1976, EPA HQ OWOW -Newport Bays (California) sewage no-discharge zone, 1976, EPA HQ OWOW -Oceanside Harbor (California) sewage no-discharge zone, 1976, EPA HQ OWOW -Richardson Bay (California) sewage no-discharge zone, 1987, EPA HQ OWOW -San Diego Bay (California) sewage no-discharge zone, 1976, EPA HQ OWOW Office request for any areas covered by more than one FR notice to be comprised of matching features. Select/add additional Hi Resolution NHDArea features to based on the extent of the original NDZ feature Match up extents between old and new feature 2019-10-28T00:00:00 Merge the feature as constructed at this point with the following existing features: -Avalon Bay Harbor (California) sewage no-discharge zone, 1979, EPA HQ OWOW -Channel Islands Harbor (California) sewage no-discharge zone, 1979, EPA HQ OWOW -Dana Point Harbor (California) sewage no-discharge zone, 1976, EPA HQ OWOW -Mission Bay (California) sewage no-discharge zone, 1976, EPA HQ OWOW -Newport Bays (California) sewage no-discharge zone, 1976, EPA HQ OWOW -Oceanside Harbor (California) sewage no-discharge zone, 1976, EPA HQ OWOW -Richardson Bay (California) sewage no-discharge zone, 1987, EPA HQ OWOW -San Diego Bay (California) sewage no-discharge zone, 1976, EPA HQ OWOW This step ensures that the areas common to multiple NDZs are identical. 2019-10-28T00:00:00 Clip feature at inland locations based on source materials. Match up extents between old and new feature 2019-10-28T00:00:00 Split the feature at the northern and souther n CA state borders. Use Editing tools to Split Polygons using state borders from the Feature Catalog for the TIGER/Line Shapefile, 2019, nation, U.S., Current State and Equivalent National dataset. Zone only covers CA state waters 2019-10-28T00:00:00 Clip the feature created in the first process using the 3nm coastline buffer. Merging the NHDArea feature and custom coastal buffer created a feature that extends more than 3nm seaward. This step limits the seaward extent to 3nm. 2019-10-28T00:00:00 Create 3 nautical mile buffer of coastline: 1. Select NHDFlowline features = 'coastline' Note - The coastline features used in creating the 3nm buffer include all coastline features in the network as well as any that compose the shoreline of any islands used in the creation of the buffer that represents the previous .version of the NDZ . 2. Add vertices to the coastline linear feature class in order to create a closed shape that can be converted to a polygonal feature class, which is more suitable for buffering. 3. Convert the resulting feature to a polygon feature class 4. Convert the linear coastline features making up the islands to a polygon feature class 5. Merge results of steps 3 and 4 6. Perform an outer buffer of 3nm on the feature resulting from step 5 7. Merge results of step 6 with the NHDArea feature that represent the Sea/Ocean The ‘NHDArea’ polygon representing the ocean water on the coast needs to extend 3 nautical miles seaward. There are numerous locations where the ‘NHDArea’ feature class does not extend far enough. Merging this feature with a 3nm coastline buffer sufficiently extends the zone. 2019-10-28T00:00:00 Seth Mann Woolpert Inc. GIS Specialist processor Features representing this No-Discharge Zone (NDZ) were extracted from the High Resolution National Hydrography Dataset (Download Date 4/29/2019). The USGS National Hydrography Dataset (NHD) Downloadable Data Collection from The National Map (TNM) is a comprehensive set of digital spatial data that encodes information about naturally occurring and constructed bodies of surface water (lakes, ponds, and reservoirs), paths through which water flows (canals, ditches, streams, and rivers), and related entities such as point features (springs, wells, stream gages, and dams). The information encoded about these features includes classification and other characteristics, delineation, geographic name, position and related measures, a "reach code" through which other information can be related to the NHD, and the direction of water flow. The network of reach codes delineating water and transported material flow allows users to trace movement in upstream and downstream directions. In addition to this geographic information, the dataset contains metadata that supports the exchange of future updates and improvements to the data. The NHD supports many applications, such as making maps, geocoding observations, flow modeling, data maintenance, and stewardship. For additional information on NHD, go to https://nhd.usgs.gov/.
