Community Activity Priority Estimated Cost Comments RW-W2 Treat stormwater High $800.00 Currently street drainage flows adjacent to each directly into the wetland basins on side of Victoria either side of the road. Due to the RW-W4 Street Low $500.00 sediment, road salts and other street to restore wet chemical the runoff from the road meadow should be treated prior to discharge to the basin. Grants from the Soil and Water Conservation District are potentially available for this work.

Hydrology primarily comes from a series of culverts that drain into a ravine further upslope. National Wetlands Inventory lists this basin as a PEM/S S I C. but currently it is more characteristic of a PEMA. The wetland is usually dry except during snow melt in the spring and after heavy rain events. Because of the slope in the wetland, hydrology is not sustained for a sufficient period of time for the wetland to be dominated by plant species typical of wetlands. It was observed that upland species are colonizing this basin due to the lack of hydrology. Dominant vegetation is mostly aggressive species such as reed canary grass, nettle, thistle, burdock, boxelder, elm, and cottonwood. The southern portion of the basin is off of park property, so building a berm to restore hydrology may be difficult.
