Unmitigated development is detrimental to the safety, welfare, and health of the citizens residing adjacent to and downstream from said development. Unmitigated development has the potential to substantially alter the natural drainage characteristics of drainage courses such that the water is diverted and thereby affects adjacent property and property owners' rights. Substantial unmitigated development in drainage courses is also detrimental to the environment of Cowlitz County.
The purpose of this chapter is to:
A.
Ensure that property owners control the volume and rate of stormwater runoff originating from their property so that adjacent and downstream property and property owners' rights are protected, soil erosion minimized, off-site sedimentation prevented and flooding potential reduced;
B.
Prevent accelerated soil erosion and sedimentation, and control stormwater runoff resulting from earth changes proposed within Cowlitz County after construction activities occur; and
C.
Maintain and protect the county's municipal stormwater facilities and the stormwater facilities located downstream of development and construction activities.
