What is an SEV?
SEV stands for Stream Ecological Valuation, and it is a method for assessing the values of a stream based on some set ecological criteria. By looking at things like what is living in the stream, what trees are growing near the stream, what the bed of the stream is made of and what stream is like upstream, we are are able to give the stream a score between 0 and 1. A stream with a score of 0 would have no ecological value, while a stream with a score of 1 would have outstanding ecological value.
Why would I need an SEV?
If you are planning a development that will require you to make a change to the stream environment such as putting in a culvert or piping a section of stream, you will need to do an SEV. The SEV score of the stream before the work is done, and the predicted score of what it will be like after the work is done will both then be used to calculate the amount of stream mitigation you will need to do to offset the negative ecological impact of the development.
How can TCEC help?
TCEC have ecologists on staff that are trained and experienced in the implementation of the SEV methodology. We would be happy to provide you with an SEV report that outlines the value of your stream. We can also develop a restoration plan for your identified mitigation site that will allow you to meet council’s mitigation requirements.[/text_output]
