Data layer displays a boundary map generated from completed habitat designs, which were developed by RestorCap and Grette Associates LLC in 2018 in conjunction with the Portland Harbor Natural Resource Trustee Council. This layer roughly represents the boundary of Linnton Mill restoration project in Portland Harbor.

Data Description:
This dataset displays the rough boundaries of habitat types which are based off of a Habitat Equivalency Analysis (HEA) conducted by NOAA and the Portland Harbor Natural Resource Trustee Council as part of a Natural Resource Damage Assessment (NRDA). The boundaries created in these layers are estimates and the polygons vary off of the NAD 1983 projection surface on which they were drawn. The habitat designs for construction were created by RestorCap and Grette Associates LLC in 2018 with oversight from the Portland Harbor Natural Resource Council.
