Impervious Surface Buildout Analysis

in support of Salmon Recovery Planning

Hood Canal Coordinating Council, 2003–2006

Objective:

Gain an understanding of how existing zoning regulations could affect the amount of impervious surfaces (IP) in the summer chum salmon habitat of the Hood Canal area.

Result:

Estimated the expected increase in impervious surfaces (IP) in Mason, Clallam, Jefferson, and Kitsap Counties if the study areas were developed as allowed under current zoning regulations. Equated the estimated IP increase with possible effects to salmon runs by conducting a GIS analysis of quantified changes in impervious surface data, parcel data, and zone data within summer chum habitats: watersheds, riparian corridors, estuaries, and nearshore.
