BACKGROUND On September26, 2005, the City Council study for this project. of a feasibility On January 9,2006, the City public hearing. the On January 23, 2006 the specifications for the project. On April 10, 2006 the City reconstruction in the PROJECT INFORMATION Susan Court, Hills The Lyman Drive South. The proposed milling and overlaying the using the pavement pavement distress will will be replaced. pavement areas and for rehabilitation segments that exhibit severe curb in various locations The City ot Chanhassen . A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play. Paul Oehme June 12, 2006 Page 2 An alternate bid for drain tile improvements was included in the bid. The drain tile is proposed to be installed at various locations to capture groundwater and provide adjacent residents the opportunity to connect sump pumps and/or draintile to the City's storm sewer system. Currently, numerous sump pumps discharge on to the streets causing drainage problems and green algae buildup on the streets and curbs. These sump discharges would be hooked up to the draintile under this project. Staff recommends awarding the bid alternate for drain tile improvements. Funding for the drain tile improvements is recommended to be 50% funding from the sanitary sewer utility fund and 50% from the storm water utility fund. Street assessments are proposed for those properties that access onto the roads within the project area consistent with the City's assessment practice. The assessments are for 40% of the street improvement cost and do not include the cost of drain tile installation in the alternate bid. The proposed assessment is $1,293.67/lot. The preliminary assessment estimate was $1,698. 15/lot. Lake Ann Park The improvements to Lake Ann Park include resurfacing most of the parking lots and drives within the park and also included two alternate bids. The base bid project includes the full depth mill of the pavement surface of the western parking lots and drives and overlaying the surface with new bituminous pavement. Curb and gutter will be installed at various locations along the parking areas to help drainage and will also be used as parking bumpers. The driveway intersection in the northeastern portion of the project area will be realigned to provide a 90 degree intersection to help traffic movements. Storm sewer improvements are also proposed in the north parking lot. Additionally, 12 new parking stalls will be added. Bid Alternate #1 includes the overlaying of the eastern parking lots. These parking lots have been evaluated and are recommended for overlaying. Distressed pavement areas will be removed and repaved. This work was bid out as an addendum due to funding limits. Because of the good bids the City received, this work fits within the budgeted CIP amount. Staff recommends this work be included in the contract. Bid Alternate #2 includes preparing several areas within the project area for rain garden plantings. Rain gardens are infiltration basins and bio-retention basins and are an environmentally friendly way of managing storm water runoff, while at the same time beautifying the area. Simply speaking, a rain garden is a landscape area that is slightly sunken or depressed to help collect and soak up rainwater rather than letting it run off into the street and drainage system and eventually into our lakes and streams. Once the gardens are planted and the plants begin to mature, the slumped area will literally be disguised and will be a nice aesthetic addition to our park landscaping. The plants, however, serve a more important function than just looking nice. They facilitate the infiltration of rainwater into the deeper soils. The plantings for rain Paul Oehme June 12,2006 Page 3 gardens are tolerant for these environments. The work in this alternate includes grading, installation of pea gravel, drain tile and top soil. A separate planting contract would be issued next spring. Staff is working with the Watershed District to help fund the planting project for 2007.
