A new wooden walkway is proposed to cross the channel at the location of the boulder weir. The improvements will also maintain the path along the east side of the channel for Lake Association use, Additional water quality improvements include the removal of silt in the remainder of the channel to Lake Josephine and removal of silt deposits at the mouth of the channel in Lake Josephine (pending DNR approval), Thc Femwood Channel basin will require periodic silt removal from City Operations and Maintenance staff to remain effective over the years. The basin's proximity to Femwood Court will make it accessible for silt removal by the City's vacuum truck. Five properties along the lower portion of Carlton Drive are candidates for rain gardens and residents have been contacted with one resident expressing interest to date.
