The final design of the improvements will be coordinated with the Lake Josephine Homeowners Association and the adjacent residents. Ramline Channel Improvements: The Ramline channel generally runs from the existing wetland between Ingerson Road and Tiller Lane to the southwest along Highway 51 until it joins with the Lambros Ditch which runs between Lake Josephine and Lake Johanna. The proposed improvements include the regrading of the existing channel to provide additional runoff detention storage capacity while introducing more natural slopes and meanders as the topography and property constraints allow. It is anticipated that a series of weirs may also be introduced into the channels to provide a permanent pool volume while allowing high flows to pass without flooding. In addition the improvements may include modifications to the existing wetland between Tiller Land and Ingerson Road to reduce the "short circuiting" of runoff along the western side of the wetland which currently exists. Any modifications to the wetland will need to be closely coordinated with the Rice Creek Walershed and adjacent property owners. Proposed Water main/Sanitarv Sewer Improvements Watermain The project includes for the relocation of existing fire hydrants along the streets proposed to be reconstructed as necessary. The proposed roadways will have different curb lines and widths from Ihe existing streets and some existing hydrant locations may conflict with the new roadway locations. Hydrants will be evaluated at the time of relocation to determine whether they should be replaced due to underground corrosion or valve control problems, etc. Replacement or relocation of a small amount of walermain to allow for storm sewer construction is also anticipated. The final scope of watermain relocation will be determined as a part of the final design. The existing watermain in the neighborhood does not have a history of excessive breakslleaks and is not proposed 10 be replaced en masse. Sanitary Sewer The project area sanitary sewers have been televised as a part of the 1999 Sanitary Sewer Rehabilitation project. The results of the televising have indicated that a large segment of sanitary sewer main within the project area is in very poor condition. Based upon review of the televising reports, the proposed improvements include the reconstruclion of approximately 850 feet of sanitary sewer. By performing the repair work in conjunction wilh the street improvements. the cost to the sanitary sewer utility fund is minimized. 7
