Discussion was held on staff's biggest concern involving the $15,000 portion of the contract for Native Seeding and Weed Free Mulching that was completed outside the seeding timeframe. Bill Bartodziej stated that seed germination is viable in the spring, and staff is relying on the disked-in mulch to hold the site until then. John stated that their subcontractor provides athree-year guarantee on their seeding work. Although John plans to complete the project on November 22, he is prepared to do spot repairs and seeding/mulching repairs next spring. Cliff felt that any extra costs incurred by the District are more than made up by Rehbein's additional costs to complete the job properly and to guarantee the seeding. He is satisfied that the District will receive added value as a result. The Board agreed to the contract extension, but Tracey asked to review the seeding contractor's written guarantee first. If not satisfactory, she will recommend that the District's retainage reflect an amount equal to the seeding cost in order to minimize the risk to the District. Proposed CIP 1`~~Iaintenance/Repairs 2003 Project Brad handed out the list of nine proposed sites and cost estimate dated 11/05/02: Site 1: Owasso Basin Overflow Structure Channel Protection - $4,650 Stabilize the pipe, constructed in 1990, through Country Drive near I-35E and I-694. Site 2: Kohlman Basin Berm and Weir Maintenance $52,200 Additional fill needs added to the berm and other areas. A third section of the weir needs to be redone to control duckweed. The second section of the same weir was scheduled as part of the CIP Maintenance/Repairs 2002 Project but was delayed until January 2003. Staff plans to drop that item from the 2002 Maintenance/Repairs contract and add it to the 2003 project instead. Site 3: Sod Fann Channel Cleanout - $3,250 Site 4: Lake Phalen/Keller Dam/Footbridge $39,500 The shoreline of the channel is eroding due to its use by shore fishers and as a canoe portage. The rip rap that used to exist is gone. Brad showed a photo as an example of a site that uses larger limestone blocks that are shaped for sitting or standing on. Since this site is Ramsey County Open Space, staff proposes to present project design and cost information to Ramsey County in the hopes that they will agree to cost-share with the District on this project. Site 5: Lake Phalen Control Structures - $450 Handrail spot welding. Site 6: Tanner Alum Facility - $3,500 Annual cleanout of sump manhole and alum injection manhole. Site 7: Tartan High School - $3,500 Manhole maintenance. The first connection below the top of the control structure needs to be sealed to maintain the proper pond level. Site 8: Lower Afton Road Drainageway $15,750 Channel slope erosion repair at Winthrop. Staff suspects this site may be generating a lot of the sediment load in the Battle Creek channel downstream. Site 9: Fish Creek Annual Sediment Excavation - $6,450 Near I-494 and Henry Place. Construction costs for Sites 1 - 9 are estimated at $129,250. After adding 10% mobilization, 30% contingency, and 25% engineering, the total estimated cost for project completion is $213,350. Page 3 November 6, 2002 RWMWD Minutes
