May 16th AWRA-WA Dinner Meeting
Ivar’s Salmon House on Lake Union
Using the SUSTAIN Model to Maximize Efficiencies in the Management of Stormwater
SPEAKER – Jeff Burkey, Project Manager, King County NPDES Phase I Municipal Stormwater Permit Watershed-Scale Stormwater Planning requirement
King County Department of Natural Resources and Parks has partnered with City of Redmond to support their development of a stormwater retrofit plan using a model ensemble of HSPF (Hydrological Simulation Program-Fortran) and SUSTAIN (System for Urban Stormwater Treatment and Analysis INntegration), both EPA model frameworks. SUSTAIN was developed by EPA as a decision-support system to facilitate the selection and placement of BMPs and Low Impact Development techniques at strategic locations. The model was utilized for a tributary in the Bear Creek watershed that predominantly lies within the City of Redmond jurisdiction. Most of the 359 acres in the drainage area is fully developed with urban level densities. The project was constructed to evaluate possible stormwater runoff control structures that included: deep well injections, bioretention, vaults, detention ponds, and Filtera). SUSTAIN scenarios were optimized using High Pulse Counts (a hydrologic flashiness metric). Effectiveness of the treatment-trains were then converted to projections of B-IBI scores (10-50 scale) as a measure of stream health if all other environmental stressors were not limiting. The project is in-progress, but the modeling results are in! Jeff will go over the model development, capabilities/limitations, and outcomes that will be used to guide development of an implementation plan.
About the Speaker - Jeff Burkey has over 25 years of experience conducting watershed assessments in the region. During the last several years, he was part of a seminal paper establishing a quantifiable relationship between stream flashiness and meaningful biological indicators of stream health (DeGasperi et al., 2009). He was part of a team commissioned by Governor Gregoire during 60th legislative session under House Bill 1303 as a team member that evaluated the effects of climate change on stormwater infrastructure (Rosenberg et al., 2010). He was technical lead on the Washington State Department of Ecology Grant (G0800618) developing watershed models and stormwater strategies needed to restore Juanita Creek to designated beneficial uses (King County 2012). He developed watershed models, projected stormwater retrofit needs based on population growth projections, and evaluated an example of climate change impacts on stormwater flow control facilities for an EPA funded Stormwater Retrofit project (PO-00J089-01) in the Green River Watershed (King County 2013, 2014, 2014), and currently is the project manager for the NPDES Phase I Municipal Stormwater Permit Watershed-Scale Stormwater Planning requirement.
