The Clarks Creek Plan represents an innovative water quality crediting and pollutant load reduction accounting system approved by the State. The Plan has created modeling tools to exact the quantitative relationship between Chinook (and other salmonids) beneficial use protection, water quality standards attainment and the amount of pollution reduction required through engineering and technology. This novel framework confirms the quantifiable link between a stormwater facility's (i.e. structural BMP) engineering and the water quality treatment (pollutant load reduction) it can reliably provide if consistently maintained.  The Plan provides a unique demonstration of how a capital project's or programmatic action's pollutant reducing performance can be quantifiably tracked and annually reported in the same metrics as the State's numerically expressed waste load allocations (clean water and vital sign targets).
