DESCRIPTION
This project is proposing to construct a water quality facility on woodland Creek to reduce the total
suspended sediment (TSS) in Woodland Creek. The facility includes constructing a hydrodynamic
separating system, and 3 cell water quality pond. The facility will be located near the intersection of
woodland Ave E and 104th Street E within Pierce County.
This project is to address the treatment of stormwater which is contributing to low dissolved oxygen
levels in Woodland Creek. The treatment of stormwater will help reduce the total suspended
sediment (TSS) in which are suspected to reduce dissolved oxygen levels.
The Woodland Creek Basin lies within Pierce County and drains approximately 1100 acres of north
central Pierce County and connects with Clarks Creek.
This project proposes to construct a water quality facility on Woodland Creek. The project basin is
approximately 446 acres of suburban basin that drains directly to Woodland Creek without
treatment. This project will intercept the flows within the roadside ditch along Woodland Ave E
Between 105th St E and 104th St E then direct the flow into a pre-treatment hydrodynamic system
prior to the water quality pond. The pre-treatment system will remove large particles, oil and floating
objects. Flow leaving the pre-treatment system will enter the pre-setting wet pond pool with
sediment collection storage then entering the second wet pool cell. After treatment the water will be
discharged back to Woodland Creek.
