Silver Creek WQFP Pilot Study   Natural Drainage Project: Roadside Ditch Enhanced with Rain Garden   Silver Creek Pilot Projects Starting in 2009, Surface Water Management (SWM) plans to conduct a WQFP pilot study in the Silver Creek watershed. This study will involve: Collecting citizen input on the design and location of proposed pilot projects, Recommending drainage projects and maintenance actions that the County can complete to improve water quality, Implementing pilot projects as funding allows, and Using study results to guide work in other areas of the county. The Silver Creek WQFP pilot study will assess both traditional and innovative techniques to manage and treat stormwater runoff. It will include the installation of Natural Drainage features, taking advantage of natural processes wherever possible to minimize disruptions to natural water movement. Natural Drainage Features Proposed pilot projects in the Silver Creek watershed include one or more of the following Natural Drainage features: Rain gardens Rain garden terraces Soil amendments Vegetated strips Pervious pavement Reduced pavement Vegetated swales Roadside ditch amendments Please see the pilot project summaries posted on this page to see proposed projects that incorporate these features. Natural Drainage Project: Rain Garden Terraces   Silver Creek Watershed: Focus Areas The Silver Creek watershed was chosen as the location for the WQFP pilot study largely because it’s a good example of areas within the county that have several small creeks, and are developing quickly. Within the Silver Creek watershed, SWM has identified several focus areas for pilot projects. Click here to view a map showing the locations of these focus areas.    Pilot Study Goals The short-term goal of the Silver Creek WQFP pilot study is to identify and implement effective water quality improvement strategies in the watershed, including projects and maintenance actions. The long-term goal of the study is to develop a model that can be applied to other areas of the county. (back to top)
