Roads and Streams

Roads are the initial impacts to watershed functions at the earliest phases of development. Roads enable all subsequent land cover changes. Roads are designed on contour, crossing drainage pathways, and so intercept both surface and subsurface flows, which are managed through ditches, that effectively expand the watershed drainage network. This changes watershed hydrology, and in our maritime climate effectively begins the dehydration of landscapes and the degradation of aquatic ecosystems.
