18S.30.100 Water Quality, Stormwater, and Nonpoint Pollution.
The intent of the Water Quality, Stormwater, and Nonpoint Pollution policies and regulations is to protect against adverse impacts to water quality and quantity.
A. Applicability. The policies and regulations of this Section shall apply to all uses and development, within all shoreline environment designations.
B. Policies.
1. Locate, construct, and operate development in a manner that maintains or enhances the quantity and quality of surface and ground water over the long term.
2. Prevent impacts to water quality and stormwater quantity that would result in a net loss of shoreline ecological functions.
3. Prevent contamination of surface and ground water and soils.
4. Minimize the need for chemical fertilizers, pesticides, or other similar chemical treatments.
5. Encourage the use of low impact development (LID) techniques.
6. Minimize the use of impervious surfaces.
7. Protect commercial shellfish areas and legally established aquaculture enterprises from damaging sources of pollution.
C. Regulations.
1. See Title 17A PCC, Construction and Infrastructure Regulations – Site Development and Stormwater Drainage. Pierce County Stormwater Management and Site Development Manual regulations are applicable and binding.
2. In addition to water quality regulations found in Title 17A PCC, water quality impacts shall be avoided as follows:
a. Operations involving substances harmful to water quality and aquatic life shall demonstrate how spills and leaks will be prevented, and how they will be responded to in the event there is a spill or leak.
b. Erosion, turbidity, stormwater and pollution control measures shall be provided both during and after construction, where appropriate.
c. After construction, the work site shall be restored to pre-project conditions to the maximum extent feasible. Any mitigation required within shorelines shall be maintained for the life of the project.
d. Development and structures shall be constructed with materials that do not leach toxic substances.
