One option that is being considered <br />is a culvert and fill crossing of the ditch. This crossing may impact wetland located in the ditch <br />and upstream of the proposed crossing. ; <br />BACKGROUND <br />An existing path has been created from Silver View Park to Silver View Road without benefit <br />of a designed trail system. The pathway crosses a ditch which drains several acres of area north <br />of the crossing. The ditch continues from the crossing south into Silver View Pond. <br />The City has pursued a bridge crossing of the ditch. However. funding for the bridge was not <br />obtained. A culvert crossing appears to be a cost effective alternative to the bridge. Stricter <br />wetland Tea lation by the State make projects near or in wetlands more difficult to build. A <br />preliminary investigation of the wetlands is required before a culvert crossing is engineered. <br />Beside providing a crossing of the ditch, the cidvert and berm znay be used to create a water <br />quality pond. A water quality pond in this Location is consistent with the Local Water <br />Management Plan's capital improvement program. A sediment pond in this location would help <br />Protect Silver View Pond. <br />SCOPE OF WORK <br />The following tasks will be performed to provide the City necessary information to determine <br />if a culvert crossing is feasible: <br />I. Site Visit: A visit to the site will give a preliminary investigation on the extent of wetland <br />that would be impacted by the project_ Both the impacts of the culvert crossinz <br />and resulting pondirng and the ability to use the area as a sediment pond Y,nd <br />be explored. <br />SHORT al LICTr <br />
