This is a study area boundary for the SMMNRA Interagency Trail Management Plan EIS/EIR. The boundary was based on the Santa Monica Mountains National Recreation Area administrative boundary and incorporates edits by Melanie Beck in December 2017 and as of April 3, 2018. Additional edits to align boundary with tracts (around ULVCOSP) and more closely to parcels where it departs tracts and NRA boundary. These edits were completed by Denise Kamradt on April 23, 2018. The boundary is divided into four sections for mapping purposes. A box was added for a cartographic mask. The remainder of this metadata describes the SMMNRA boundary. Edited by Denise Kamradt on 10/9/18 to add private parcels between developed area in Pacific Palisades cut-out and Topanga State Park. Parcel numbers 4431023028 and 4431022003 were added based on 2016 LA County parcel data. Edited 11/6/19 to match Study Area versions from 10/11/18.

This is an interim boundary which registers to tracts as of 8/5/2014. Created using dissolve on NRA item in tracts and edited to remove internal sliver polygons and errors related to the incomplete tracts shapefile (currently being developed from assessor parcels). Edited on 5/5/2015 and 5/8/15 to remove erroneous hole in NRA polygon. No official changes have occurred since 2002. All following metadata is copied from NRA_2002: This GIS layer contains the legislated boundary of the Santa Monica Mountains National Recreation Area (SMMNRA) as of the 2002 boundary expansion. Land within this boundary is NOT all public park land and about 40% of the land within the SMMNRA is privately owned. The data were produced by dissolving the boundaries of the SMMNRA tract ownership map so that only the outer boundaries of the polygons within the SMMNRA boundary remain.
