The agencies are Public Works meeting monthly to work on the bridge and road design. In addition to the Highway 7901 Park Place 101 bridge, Highway 101 /CSAH 61 (old 212) intersection, known as the "Y" Phone: 952.227.1300 intersection, will be reconstructed with a roundabout to accommodate future traffic Fax: 952.227.1310 demands. This design also accommodates a future north leg to the roundabout. Senior Center CSAH 61 will also be reconstructed to a 4 -lane design from Bluff Creek Boulevard to Phone: 952,227.1125 just east of Highway 101 /CSAH 61 roundabout. A roundabout is planned at the Fax: 952.227.1110 intersection of CSAH 61 and Bluff Creek Drive. The intersection at CSAH 61 and Highwayl01 north leg will still operate with a signal until the alignment up the bluff Web Site is improved. www.ci.chanhassen.mn.us Chanhassen is a Community for Life -Providing for Today and Planning for Tomorrow Todd Gerhardt Highway 101 MN River Crossing /CSAH 61: Update February 10, 2014 Page 2 PLAN REVIEW Plans are 95% complete and agencies are reviewing the final details of the project. Currently, Carver County is working on right -of -way negotiations. Right -of -way acquisition is expected to be completed by February of 2014. The Chanhassen entrance monument on the south side of the roundabout is included in the project. The Federal Highway Administration does not recommend placing fixed object in a roundabout, however, MnDOT does not have a policy for this. Carver County has agreed to allow the entrance monument within their right -of -way, however, they are requesting the County not be held liable for any accidents that may occur. This will be outlined in the Joint Powers Agreement. Modest landscaping in the roundabout is included in the project. The plantings chosen are relatively low maintenance which include grasses, ornamental and coniferous trees, shrubs and perennials. This area currently does not have City water service so irrigation of the landscaping is limited. An option to irrigate the roundabout is to use the stormwater ponds adjacent to the roundabouts as the water source. This irrigation design and construction would need to be bid outside of the road project contract. However, conduits should be installed with the road project to plan for the irrigation improvements. Staff is checking on the feasibility of the design and if any grant funds are available. Three stormwater treatment ponds are proposed for the project on the north side (Chanhassen side) of the river. The pond southeast of the Highway 101 roundabout is a regional pond that will treat stormwater from a portion of the Hennepin County project scheduled for construction in 2015 and the north leg of Highway 101 up the bluff. Bridge trail railing design is proposed to be the same design that is on Highway 494 Lakota Bridge in South St. Paul which crosses the Mississippi River (see photo below). The railing is proposed to be painted a dark brown. Two overlooks or rest areas are also proposed on the bridge trail. The overlooks will have interpretative panels at these locations discussing the cultural history and ecological wonders of the Minnesota River basin. The Highway 101 bridge will have some street lights on the road curves and around the roundabout. CSAH 61 will have street lights at the Bluff Creek Drive roundabout. These lights are proposed to be LED instead of the normal high pressure sodium (HPS) lights the City currently is using. The lights are expected to offer the same illumination as the HPS lights but are more energy efficient and will have a longer life expectancy. The poles are proposed to be brown anodized aluminum. g: \eng \public \_2013 projects \13 -04 th 101 river crossing - csab 61 improvements \bkgd 021014 update on 101 bridge and wye imp.doc Todd Gerhardt Highway 101 MN River Crossing/CSAH 61: Update February 10, 2014 Page 3 The project will have several detours throughout the project to maintain access to the local businesses. Estimated Project Costs The total estimated project cost is $56,232,000. The City of Chanhassen will be responsible for a portion of the project based on requested items included in the project and Carver County cost share policy. Scott County's share is their future tumback plus the LRIP funds. The two Counties are planning to pay for their Highway 101 approaches and split the bridge funding shortfall 50150. The trail costs are not turnback funding eligible. The Highway 101 trail corridor is on Carver County's master trail plan so the trails, underpass and associated retaining wall will be split 50150 between the City and County. The trail improvements along CSAH 61 are 100% City cost. The aesthetic treatment in the roundabouts and entry monument are 100% city cost. A portion of the CSAH 61 project is not tumback eligible. These costs are proposed to be charged to the City per the Carver County cost participation policy. Right -of -way is 75% tumback cost eligible along CSAH 61. The 25% of the remaining right -of -way cost is proposed to be split between the Carver County and the City per past projects. The following is a breakdown of the estimated City costs: CSAH 61 Roadway City Share Not Tumback Eligible Per Carver County Cost Participation Policy $180,088 Highway 101 Trail City Share $194,492 CSAH 61 Trail F $67,704 j Roundabout Aesthetics and Entry Monument F $100,678 City's Engineering Share of Design $54,296 Right -of -Way City Share F $234,375 Total City Costs F $831,633 The City received a Minnesota DNR trail grant for this project in 2013 in the amount of $150,000. The remaining City cost is proposed to come from the Municipal State Aid (MSA) Fund. Staff is still checking with State Aid about all items being eligible for state aid.

The Minnesota River drains a basin of 16,600 square miles in all or parts of 38 of Minnesota's 87 counties, as well as portions of North Dakota, South Dakota and Iowa. The Minnesota River flows 335 miles from its source in Big Stone Lake to its confluence with the Mississippi River at Fort Snelling, in Mendota. The Minnesota River is the largest tributary to 1 _ the Mississippi River. In fact, the flow of et from Big Ston the Mississippi River doubles at the Lake (elev. 964') to the confluence with the confluence with the Minnesota River. The Mississippi River (elev. 690'). It drops approximately basin is one of 10 major watershed basins the height of a notebook (10 inches) each mile. in Minnesota and is subdivided into 12 �Ul—a.:�,m hydrologic major watersheds and 13 U"- 0W°°I- y— `t`.Pu'brx' management watersheds. 900- l �IIOiR .h,F+O 4'. x...u�m WA. 160 100 50 The Minnesota River Valley was carved from the glacial melt water of Lake Agassiz about 12,000 years ago and continued to flow for about 2,000 years. The discharged meltwater was sometimes up to five miles wide. Once these waters subsided, the valley looked very )timilar to what you see today. 0 200 400 600 600 feet Wlooding is a natural occurrence of a river's valley that can cause damage in areas inhabited by . that also has many benefits, including recharging groundwater and supporting valuable wildlife habitat. A flood occurs when a waterbody receives a greater volume of water than it can handle in its watershed, either at spring snowmelt or during a heavy rain event. 0 —900 —600 -300 —600 —500 -400 -300 MINNESOTA RIVER VALLEY THE PEOPLE AND NATURAL WONDERS Near this location, and for at least 8,000 years, Native people hunted, gathered and camped along the shores of Rice Lake, which was much larger and has gradually filled in with wetlands. These Native people hunted bison, elk, deer and other game. They fished with spears and nets, and harvested clams for their meat and shells. They also had a gathering lifeway and cultivated crops of corn, and gathered plants such as quinoa, wild rice and berries to supplement their diet. The Minnesota River, Mni Soto Wakpa, and its tributaries served as natural highways that facilitated the movement of people, cultural and trade items, and allowed for seasonal gatherings. The most recent inhabitants of this valley, the Dakota people, consider the valley, and especially its confluence with the Mississippi River, to be Wakan, or sacred. The term Minnesota is derived from the Dakota word,mY Mni -sota, meaning cloudy or smoky water. Native American presence in the „r r= valley was greatly reduced in the mid -19th century due to a series of treaties with the U.S. government and conflicts with ^ ^° Euro- American settlers, climaxing with the U.S. and Dakota War in 1862. Subsequently, Euro - American settlers moved into the valley and have formed their \�- s. own connection with the Minnesota River.d.. *� a . .. yym .

Early settlements were established nearly simultaneously between 1850 -1855 along almost the entire length of the Minnesota River, driven by the prospect of river landings and riverboats The towns of Shakopee and Chaska were both platted and established in 1851. Forma establishment of Scott County occurred in 1853, and Carver County in 1855. Agriculture an associated industries like milling, food processing, brick- making and limestone quarryin contributed to the growth of neighboring communities like Carver (1852); Chanhasse (1852); Prior Lake (1891); Hamilton (no E _r.� `-_"`A _ �out'`1rdtob years ago, the glaciers melted back into northern Minnesota and adjacent North Dakota. Glacial meltwater was trapped behind the Big Stone Moraine, creating Glacial Lake Agassiz in today's Red River Valley. This ancient lake eventually covered an area larger than the Great Lakes combined, with a maximum area of about 123,500 square miles and a maximum depth of 400 feet, although Lake Agassiz was never this large at any one time S during its 4,000 Year history. Its different stages are marked by relic beaches, many named after northwestern b, Lake Agaesli. Minnesota towns (e.g., Herman, Tintah). on over - topped the Big Stone Moraine near 'present- ay Browns Valley and meltwater- engorged Glacial River Warren formed in what was to become the Minnesota River Valley. About 12,500 years ago, the moraine dam failed and a catastrophic flood carved much of the Minnesota River Valley as we know it today. Glacial River Warren exposed bedrock outcrops, created steep bluffs, and laid open a wide floodplain through which Mni Soto Wakpa (Minnesota River) now snakes its much slower path. mmunities —the floodplain, the wooded bluffs and till surrounding prairie — offered a wide variety of resources to sustain the occupants of the valley. The river and the floodplain provided habitat islaquatic mammals, waterfowl and fish, as well as aquatic plant life, izarl d rice, water lilies and cattails. Deer and occasionally elk occupied e timber fringing the valley full of edible berries, Morel Mushrooms innesota's State Mushroom) and Maple Trees, while bison roamed e surrounding expansive tallgrass prairie. Here, too, grew tipsinoh airie turnips), ptetawote (ground plums) and other edible prairie nts. .A Ng 6 BC �RF AN c9 O,fl CSp�GJO k Ee CgC�OUQ QR1 lF �--( tNG X 3iuWWWWWWWWJ SCALE IN FEET � 200 —PD SHORT /DRY PRAIRIE SEED MIX SEE MANUAL i WS CSAH 61 (FLYING CLOUD DR) E CC,0 G GRl G CL PLANT SCHEDULE - SMALL RAB KEY QTY COMMON NAME /BOTANICAL NAME SIZE ROOT SPACING GRASSES Ihereby certify that this clan was areaare. by me or urger PD 1 200 1 PRAIRIE DROPSEEO /SPOROBLUS HETEROLEPIS 1 N1 CONT. 1 24" OC CARVER COUNTY, YN, 1566 SF SHORT /DRY PRAIRIE SEED MIX LEGEND SHORT /DRY PRAIRIE SEED MIX PLANTING BED LAYOUT DESIGN TEAM Ihereby certify that this clan was areaare. by me or urger CARVER COUNTY, YN, FA.E N0. 1 L"T my mrect v+oervlsmn arw that I am a awy ucenm.
