ARRA 15 Village of Sussex Spring Creek Grant 2P-00E73201

Purpose

Spring Creek planning and study of culvert removals and stream restoration of Spring Creek, an impaired waterbody.

Objective

Develop a strategy to remove man-made barriers to this waterway and restore a natural stream flow pattern. Collect data to be used in a study on the water quality benefits and treatment of urban pollutants through restoration of natural stream segments in suburban areas, including the capacity for mitigating urban runoff impacts, through: • more evenly-dispersed flow through natural meanders and in-stream vegetation during storm events as compared to piped systems; • nutrient uptake by in-stream and nearby vegetation; • incorporation of sediment into restored streambed; • transport of “normal” amounts of sediment downstream, as compared to excessive scouring of streambed due to current “flashy” type of system • evaporation and infiltration of runoff throughout the drainage area, rather than depositing excess water in the downstream reaches of the basin • temperature stabilization

Outcome

A detailed plan describing the strategy for removing artificial barriers to the stream system which could be adopted by local units of government, to be used for development of infrastructure and downtown re-development planning. Recommendations from this plan could be adopted by other communities with similar stream obstacles. The study would determine if there is a water quality benefit to daylighting and restoring other stream segments in semi-urban communities by allowing runoff to be treated by the natural ecosystem, as opposed to directing water away to the nearest downstream surface water. Other previous studies around the country have primarily focused on the habitat values of daylighting projects, as opposed to water quality improvements. Results of this study could be considered in deciding other water quality projects to implement in the region.
