Johnson: <br />This letter is in reference to your telephone request regarding <br />the wetland evaluation report delivered to the City Council of <br />Mounds View on September 26, 1983. Specifically the question was <br />whether the 1.1 acres of land referred to as 1-22 in the Miller <br />property functions as a wetland. <br />A wetlands capabilities include 1), the ability of the vegetation <br />to remove nutrients from surface water runoff which flows through <br />the area 2), the ability of the area to retain water ariai.ng from <br />surface runoff for a period of time and, 31 the ability of the <br />area to support those, types of wildlife requiring a wetland <br />habitat. <br />This area (1-22) has vegetation typical of a wetland and there- <br />fore falls within the definition used to classify wetland areas. <br />However, this area does not function as a typical wetland. Most <br />wetlands perform their functions for a larger geographic area <br />outside of their own boundaries. They retain surface water <br />runoff from the larger area. They remove nutrients from surface <br />water runoff that occurs over a large area and becomes con- <br />centrated in a wetland. They provide habitat for wildlife wnich <br />utilize the wetland as a home or base area from which thoy roam <br />and inhabit » much larger area. <br />Because of the limitations placed on 1-22 such as being <br />surrounded by roads and being landlocked, this area is not able <br />to act as a wetland for a larger geographic area, and rather only <br />serves that small portion which is in the northwest voroer of the <br />property. The small size of the area in question greatly li.mits <br />its ability to store water from surface runoff other than that <br />which falls within its own boundaries. It's small size and land <br />locked condition greatly limits it's ablility to remove nutrients <br />Envirdnmemal Tesllnp and Consulllnp Sorvicas <br />�i)` , Mal annra IN'. Okla 0 WObna. a1 De,a.
