Construction: What are the minimum changes to the current creek design needed, versus what are some options in creek modification design that can enhance natural stream flow and wildlife?
Geotechnical: The City of Sun Prairie is considering installing holding ponds on some current city-owned property, are there other options for building those ponds for the ground to hold water? Additionally, if a pond is built with a blue clay liner, how will surrounding land parcels be affected? Are there potential technological developments in the planning horizon that could radically alter how treated sewer water is ultimately handled, like recharging the groundwater?
Geospatial: This will be critical in the inventory phase, to accurately determine just what is constructed presently, and where does it make sense to make efficient changes?
Hydrologic/hydraulic: Several property owners in the area are affected by flood zone mapping requiring thousands of dollars of flood insurance annually. Is the flood zone mapping accurate? If the creek is modified, could the flood zone change, and if so, how. (The goal here is not to change the FEMA maps, but to come up with alternatives in creek design to help mitigate future flooding, we will therefore need to exhibit that reduction in flooding.)
Additionally, several farmers have had their lands noted as wetlands on zoning maps, but their land can be farmed in dry years. Thereby is the classification correct, and if the creek is modified so that floods can again become less frequent, how does the wetland delineation get corrected?
Structural: What is the preferred construction of revised channels within the creek, and what design is the easiest to maintain in the long term?
Transportation: While the creek is too small to handle commercial transportation in the long run, it certainly is open to recreation aspects and those could be studied. If the creek is to be modified, what will be the costs of bridge infrastructure modifications, and how should creek protection be considered in those improvements
Ecological: What can be done to improve the ecology of the creek and watershed, to possibly improve the scoring of the creek so it isn’t considered impaired?
