The Kincaid Ravine Bioswale Hydrological Assessment seeks to conduct a feasibility and assessment study on potential hydrologic modifications and designs for a bioswale in Kincaid Ravine will not only help address the issue of flooding on the Burke-Gilman Trail at the edge of Kincaid Ravine, but will also add to the ongoing efforts to restore the ecological functions and habitat of the previously underutilized and ecologically degraded four acre open space located in the northeast corner of campus.
This assessment will focus on characterizing the quality and quantity of the water moving through Kincaid Ravine and determine the feasibility of constructing a bioswale that will help alleviate flooding and allow for better stormwater treatment, storage and infiltration in Kincaid Ravine. This will require lab testing for water quality and soil and some hydrologic monitoring and modeling to determine the amount of water moving through the ravine during the wettest months. In congruence with the soil and water quality testing (which will be done on campus), we will use outside consulting from the group 12,000 Rain Gardens in Puget Sound to help provide assessment of current hydrology (approximate volumes and sources of water, outflow volumes, and soils assessment), bioswale feasibility assessment, summary report of hydrology and feasibility, and bioswale basic design (approximate elevations and planting plan).
Developing this assessment study instead of moving hastily into design and construction is a prudent first step in properly addressing the hydrology issues in Kincaid Ravine and making sure the numerous groups and administrative interests associated with Kincaid Ravine are all satisfied with the work going forward.
