- 2 - <br />2. Work Request No. 2 (Attachment No. 2) - Joseph P. Weaver <br />requests that the City improve t -e rainage ditch in the <br />hack of their yard because ponninq water almost flowed <br />into th#•ir basement through their back door this <br />Apr 1na. Mr. Weaver also indicrted that other neighbors <br />in the area are willing to sign this petition also. <br />Staff ir presently detPrmin(nq if the City has an <br />easement over Mr. Harstad's property. An easement over <br />Mr. Harstad's property is necessary in order to <br />constnurt a drainage ditch which f!ows to the east. <br />Iiavinq storm water flow to the east is the only way that <br />water can flow without installing storm sewer pipe. <br />J. Work Request No. 3 (Attachment No. 3) - Doug and Kay <br />WPaeman request that they solve the pondiiq water <br />problem that is by the nutlet to the storm sewer that <br />runs between 7551 and 7807 Bona Road. The ditch problem <br />next to their house is a symptom of a larger ditch <br />problem. The larger problem is that the bottom of the <br />ditch through the wetland to the east of their house has <br />silted in such that it is higher than the elevation of <br />the invert (bottom inside) of the storm sewer pipe. The l , <br />City is in the process of securing grant funds from the <br />Rice Creek Watershed District to clean the ditch to the <br />wetland. The estimated construction cost of this <br />project is $60,000. <br />The other area of concern is the erosion on the ditch <br />banks in the ditch between the two houses. My opinion <br />is that the storm sewer should be extended to the east <br />because the banks of the ditch are ton steep to handle <br />the large flow of storm water. Another way to handle <br />the steep bank problem is to install retaining walls. <br />The entire project depends of receiving adequate funding <br />from Rice Creek Watershed District. <br />4. Work Re uest No. ! (Attachment No. 4) - Four property <br />owners located near 3 Kno wood Drive have requested <br />that the City solve the water ponding problem.

However, the water table is high and <br />continues to <br />
