Description of Urban Land Use as a Human Activity Affecting Fish Habitat in Pacific Coast States

from the National Fish Habitat Partnership's 2015 Through a Fish's Eye Report

Summary

There are three designated megaregions in the Pacific Coast States: Southern California, with a population of 22.4 million; Northern California, with a population of 14.6 million; and Cascadia (from Vancouver, British Columbia to Eugene, Oregon), with a population of 8.4 million. These areas have enormous effects on both the inland and coastal aquatic habitats. Continual development increases areas of impervious surfaces (completely altering natural water flows and hydrology) and the amount of sewage discharge, sediments, and other pollutants associated with urbanization. Ever increasing urban water needs can be far reaching and affect systems and fish habitat far away from the urban areas. Los Angeles, which is located in a semi-arid [...]
