Goldcrest Brook: A Case for Stormwater Management
Presentation by Peter Dalrymple
Dalrymple presented information learned from the City of Salem’s
study of the rapid and extensive erosion along Goldcrest Brook,
a tributary of Glenn Creek. The City became engaged in this
study in 2018, when streamside landowners along Goldcrest Brook
reported rapid bank erosion. View

The presentation included an explanation of hydromodification (a blanket term for how alterations in land use change the hydrologic characteristics of streams), the study’s look at changes in Goldcrest Brook over time including development in the watershed, impacts of the development, ongoing monitoring of the stream channel and flows, and possibilities for minimizing the impacts of development going forward.
Consultants are at work creating a model to help better understand hydromodification and how to create rigorous stormwater design standards to better protect stream channel integrity, water quality, aquatic life and streamside property. Riparian buffers, access corridors and good utility data are all part of the solution to protecting streams through the process of development in the watershed. Since restoration of these streams is difficult, protection is important.
