Natural System and Location:
Various Natural Systems - Range of prairie types, oak savanna, mesic forests, and various wetland types (wet prairie - emergent systems and ephemeral and perennial systems) and streams and ponds all in five SE Wisconsin locations: Germantown, Caledonia, and Oak Creek.
|
|
Hypothesis/Goal:
Test effectiveness of STT for storm water management compared to conventional storm water management. Goals involve testing the differences of STT vs. conventional methods of storm water management by quantification of biodiversity, hydraulics, hydrology, water quality and ecotoxicity, and costs of the treatment methods.
|
|
Restoration Strategy:
Design hydraulic performance to match hydrographs of hypothetical natural system(s) using STT integration with native landscaping, restoration of savannas, forests, wetlands, prairies, etc. within integrated open space systems in the 3 model conservation development projects. The process of restoration would follow the process, hypotheses and methods in Apfelbaum and Chapman 1997 (Ecosystem Management, Yale Press). Applied Ecological Services will monitor the effectiveness of stormwater treatment trains in improving water quality and flow during and after construction. AES will construct Stormwater Treatment Trains-vegetated swales that convey runoff, wetlands that remove nutrients and sediment, and sedimentation basins and stages release outlets-at three developments in southeast Wisconsin. The project will evaluate the ecological impacts of, and costs associated with, three watershed sensitive developments and compare them to pre- and post-development conditions and traditional residential developments.

|
Anticipated Outcomes/Environmental Affects:
- Technical and layperson papers documenting benefits of STT vs. conventional storm management engineering strategies.
- Proposed changes to storm water ordinances to allow for incorporation of STT in future developments.
- Technical data to use for comparison and development of standards for storm water management with respect to biodiversity, hydrology, hydraulics, water quality, and ecotoxicity.
- Establishment of regional demonstration projects for STT.

|
Progress to Date:
Completed plans for design and monitoring of 3 watershed sensitive developments and monitoring of 2 conventional developments. Storm events sampled and biodiversity measurements being taken at all sites. Received initial baseline monitoring assessments for proposed development sites in Germantown, WI and Caledonia, WI.
