~i ®uucll Study Sessi®n 11~~nday, July 16, 2Q07 Page 15 be made at tonight's meeting, simply a presentation by staff and dis- cussion for possible future action. Public Works Director Duane Schwartz and City Engineer Debra Bloom provided their detailed recommendation, as outlined in the staff report dated July 16, 2007, for stormwater improvements in this area. Staff's noted that the vacant lot was owned by the George Reding es- tate; and their recommendation was to proceed with their alternatives 2 and 4 to consider negotiating purchasing the vacant lot identified as 806 Brenner; regarding the lot to connect the vacant lot to manhole #105; disconnection of catch basins # 1, 2 and 3 from Charlie Pond piping and connect it to Lake Owasso piping; reconnecting the catch basin/manhole north for high overflow; and making improvements to the Avon low point. Staff advised that this project could be incorpo- rated with several other small projects to obtain better bids, with a feasibility report brought back to the City Council for approval and authorization prior to going to bid. Staff noted that the construction was not dependent on purchase of the lot, but would be an integral part of the solution; and proposed to work with property owners on potential purchase; however, staff noted that they were unaware of the interest or willingness by the owners to sell the parcel. Discussion included timing of property purchase negotiations and construction timetables; impacts of water flow into Lake Owasso rather than Charlie Pond and water quality goals; soil type considera- tions (clay versus sand); sizing of pipes and incremental cost impacts; Current pipe locations and sizes; industry-wide determinations for stormwater event calculations and probabilities; cost benefits; and es- timated costs. Ms. Bloom advised that, with Council direction, it was staff's intent to put a prof ect together for Council approval at an estimated cost of $..102,000 yet this fall.
