Proposed Timeline Bids will be received in February 2014. Construction is expected to begin in April 2014. Substantial completion and cleanup will be in late November 2014. Project closeout is summer of 2015. Item 6. Project Description The purpose of the project is to improve safety, ease projected congestion, and address necessary improvements to accommodate the future traffic growth related to the existing Chanhassen High School and other adjacent developments in the area. The need for the project is identified in the Carver County Transportation Plan (2007). Carver County is experiencing a high level of population growth, with most of the growth taking place in the central and eastern portions of the county. The cities of Chaska, Chanhassen, Victoria and Waconia are estimated to account for over half of the total County population by 2030. The 2030 County population forecast is almost triple the year 2000 population. Due to the current and expected future population growth, congestion in areas of central and eastern Carver County is expected to rise on County facilities, occurring frequently during the peak hours. Without the proposed project, the CSAH 18 corridor will continue to experience increasingly unacceptable levels of congestion and associated safety issues. Safety information, including crash data, is presented in Appendix F. The purpose of the specific impacts to the wetlands, as previously described, includes roadway fill impacts. Proposed Improvements This project involves reconstruction of the segment of CSAH 18 from approximately 800 feet east of CSAH 15 (Audubon Road) to approximately 700 feet east of CSAH 17 (Powers Boulevard), in the City of Chanhassen (see Figure 2a Appendix C). This project will accommodate safety and capacity improvements to the roadway facility, as well as drainage and stormwater management, access management and a pedestrian/bicycle facility. The construction plans have been developed to minimize impacts to wetlands, water and other natural resources. Several existing stormwater management ponds will be utilized to accommodate runoff from the additional pavement within the project area. Wetlands that are proposed to be impacted are located within the right of way and at the toe of slope of the existing roadway. Impacts are directly related to the proposed improvements. Item 8. Sequencing Considerations Wetland Impact Avoidance The No Build Alternative is the only alternative that would completely avoid wetland impacts. However, the No Build Alternative would not address current safety and capacity issues in the project area. Therefore, the No Build Alternative was considered to be not feasible. Alignments slightly to the north and to the south of the existing alignment were assessed; however, the least wetland impacts were found with the proposed alternative. Wetland Impact Minimization Remaining unavoidable impacts were minimized to the extent practicable with steeper side slopes through the highway sections that are adjacent to wetlands, thereby minimizing the roadway footprint through these areas. Side slopes for the proposed road improvement were generally 1:3 in the vicinity of wetlands and 1:4 elsewhere. Slopes steeper than 1:3 present vehicular safety issues and can require installation of guard rail. Guard rail can make snow removal more difficult. Retaining walls were considered early in the planning process; however, the costs of installing them were prohibitive. Retaining walls would have required additional excavation of unstable soils and more surcharge than with a sloped design. Appropriate silt fencing and its proper installation will be specified on plan sheets for areas of the road improvement that are within 50 feet of wetlands. Anti-erosion measures will include rapid re-vegetation of side slopes with cover crops and eventually with appropriate MnDOT seed mixes. The widths of road lanes, medians, dedicated turning lanes and clear zones were designed according to State Aid Design Standards. While design exceptions from standards and guidelines in this Manual are sometimes possible, such exceptions incrementally diminish roadway safety. The two-way bicycle/pedestrian trail was designed according to standards and guidelines listed in the Minnesota Administrative Rules 8820.9995 State Aid Minimum Bicycle Path Standards and the MnDOT Bikeway Facility Design Manual. Design exceptions from standards and guidelines are sometimes possible, but such exceptions can diminish the safety of the trail. The trail alignment is adjacent and contiguous with the road. This design minimizes wetland impacts as a portion of the trail embankment is shared with the road embankment. The boulevard width between the trail and proposed curb was reduced through the wetlands in order to further minimize wetland impacts. Mitigation for Unavoidable Wetland Impacts Onsite wetland mitigation was considered early in the planning process; however, the costs of acquiring right-of-way for a relatively small amount of required wetland mitigation was prohibitive. Purchasing existing credits from a suitable wetland mitigation bank within the same Major Watershed and Bank Service Area as the wetland impacts was cost-effective and would result in wetland mitigation that is already known to be functioning acceptably. Unavoidable permanent wetland impacts will be mitigated through the BWSR Road Replacement program (Item 17 Appendix A) and through an approved State Wetland Bank (Item 21 Appendix A). In areas where wetlands are immediately adjacent to the existing roadway toe-of-slope, temporary impacts due to muck removal to stabilize foundation soils, will be restored to preconstruction conditions by re-grading to original contours. These temporary impacts are quantified in Item 9B below. It is anticipated that temporary wetland impacts would not require mitigation other than restoration to pre-construction conditions. Temporary impacts will be stabilized with a combination of Types 1, 2, and 3 Rapid Stabilization methods. Type 1 is disk anchoring. Type 2 is application of mulch and hydraulic application of a tackifier. Type 3 is application of Seed Mix #190 in combination with fertilizer and tackifier. Item 9a. Impact Summary: Impacts to Lakes and Watercourses A Minnesota Department of Natural Resources (DNR) Public Waters Work Permit (Permit Number 2014-0526) has been issued for work within Bluff Creek (M-055-014) – Appendix D. Item 9b. Description of Wetland Impacts The proposed wetland impacts are located in Carver County, in the Minnesota River – Shakopee (33) Major Watershed and Bank Service Area 9 – Metro Area. Table 1 below lists the proposed impacts to wetlands located within the project area. The proposed wetland impacts are shown on Figures 3A through 3C (Appendix C). Refer to Item 6 for a complete description of the proposed project. A total of 1.88 acres of permanent wetland impact and 0.16 acres of temporary impact are proposed as a result of the roadway reconstruction. Of the 1.88 acres of impact, 0.33 acres are permanent and safety-related and 1.55 acres are not eligible for safety credits (See Appendix E and F for Safety information). The permanent safety-related impacts include 0.13 acres of impact to Bluff Creek, a DNR Protected Watercourse, and are associated with culvert replacement, grading, and rip-rap for culvert outfall within the channel north and south of Lyman Boulevard. As described in Item 8. Sequencing Considerations above, a total of 0.16 acres of temporary impacts will be restored to pre-construction conditions.

These crashes include 15 personal injury crashes and 40 property damage crashes. According to MnDOT’s crash data from January 1, 2007 through December 31, 2011 and locally-collected data, there have been a total of 42 crashes on CSAH 18 within the project area. These crashes include 14 personal injury crashes and 28 property damage crashes. Thus, a total of 97 crashes have occurred on the subject road improvement between January 1, 2005 and December 31, 2011. Additional crash data are appended to this supplement and demonstrate that the crash rate in the subject road improvement is considerably higher than similar roadway in the Twin Cities Metropolitan Area. See Attachment 1.In addition, unsafe conditions for pedestrians result from the lack of a pedestrian facility along CSAH which has a 50-mph speed limit and high traffic volumes along the corridor. Existing (2010) traffic volumes along CSAH 18 in the project area are approximately 8,800 vehicles per day (vpd). Future (2030) traffic volumes are forecast to be approximately 23,000 vpd (Lyman Boulevard Phase III Traffic Analysis Update, SRF Consulting, dated January 12, 2012). This includes traffic generated from the new Chanhassen High School. Traffic operations were analyzed for existing (2010) conditions and for future forecast No Build conditions (2030). Capacity analysis (level of service (LOS)) was used to examine the operational characteristics for key intersections within the project area. LOS is a relative comparison of the ability of an intersection to function and accommodate traffic flow. The LOS of an intersection is generally presented as a rating from A through F, with A having the least delays and F having substantial delays. In the metropolitan area, an intersection with an LOS of D or better is considered to be operating at an acceptable level. Congestion results in safety issues. The following text describes safety improvements along the proposed Phase 3 reconstruction Lyman Boulevard (CSAH 18). In general the roadway will be reconstructed from a 2-lane undivided highway to a 4-lane divided highway with medians. The presence of the proposed medians will reduce the potential for head-on vehicle collisions. Audubon Road (north) and Lyman Boulevard (CSAH 18) Currently, eastbound traffic on Lyman Boulevard waiting to turn left onto northbound Audubon Road stacks up, forming a queue that blocks the left turn bypass lane. Thus, motorists who wish to travel past Audubon Road are often caught in the left turn queue and tend to make abrupt turns into the through lane leading to rear-end or side swipe crashes. The proposed dedicated left turn lanes from eastbound Lyman Boulevard to northbound Audubon Road allow turning traffic to seek refuge without interfering with eastbound through traffic, thus reducing the potential for crashes. Eastbound traffic on Lyman Boulevard turning north onto Audubon Road can use the median width and the westbound dedicated left turn lanes as refuge as drivers gauge gaps in the westbound traffic before they traverse the westbound through lanes to complete their turn. Powers Boulevard (CSAH 17) and Lyman Boulevard (CSAH 18) The regional recreational trail runs alongside the west side of Powers Boulevard where it crosses Lyman Boulevard (CSAH 18). A porkchop island will be constructed in the southwest quadrant of this intersection in order to allow trail users refuge from heavy traffic as they cross Lyman Boulevard. Traffic signals will be push button actuated for the benefit of pedestrians and trail users trying to cross Lyman Boulevard. The porkchop island will also serve to channelize heavy vehicular traffic turning from eastbound Lyman Boulevard to southbound Powers Boulevard. This channelization and dedicated right turn lanes will decrease the potential for rear-end crashes which result from conflicts between turning traffic and through traffic. An additional left turn lane from north bound Powers Boulevard to westbound Lyman Boulevard is proposed because heavy left turning traffic at this intersection tends to stack an unacceptable distance south on Powers Boulevard. This long queue interferes with the north bound through lanes on Powers Boulevard and tends to increase the potential for rear-end crashes. The heavy traffic needing to turn from northbound Powers Boulevard to westbound Lyman Boulevard is partly the result of the new Chanhassen High School built in 2009. Sunset Trail and Lyman Boulevard (CSAH 18) The intersection of Sunset Trail and Lyman Boulevard (CSAH 18) is at the top of a relatively steep hill. Thus, vertical sight lines are dangerous and there is a high potential for side-impact crashes as vehicles enter CSAH 18 from a current driveway. This driveway will be relocated to a side street and the approach grades on CSAH 18 will be flattened to increase the vertical sight distance and reduce the potential for side impact crashes. The reconstruction of this intersection will have dedicated left turn lanes on CSAH 18. This will greatly reduce the potential for rear-end crashes resulting from conflicts between turning traffic and through traffic. Trail Alternatives The No Build Trail Alternative was considered and rejected because it would not serve to provide continuity in the regional trail system. The location of the trail on the north side of Lyman Boulevard (CSAH 18) was largely driven by the location of the trail segment constructed during Phase 1 of this roadway improvement – also on the north side of Lyman Boulevard. The construction of the new Chanhassen High School in 2009 on the north side of Lyman Boulevard also was a driver for trail location.

Table 2: Comparison of Lyman Blvd Segment Crash Rates with Mn/DOT Metro District Crash Rates for Rural 2-Lane Segments Segment Crash Rate = 4.36 crashes per million vehicle miles 0.80* (1.33)** Segment Severity Rate = 6.33 1.20* Segment Crash Density = 14.00 crashes per mile per year 4.40* Segment Crash Cost^ = $232,734 per mile per year * The Mn/DOT Metro District average crash and severity rates and crash density are based on the 2007-2011 Average Crash Rates for Rural 2-Lane roadways in the Metro District crash rate data. ** The Crash Rate shown in parentheses is the (Critical Crash Rate) based on and calculated using the related average crash rate. The critical crash rate provides a statistically relevant crash rate benchmark. ^ Note that crash cost is based on the following costs by crash severity: F: $560,000, A: $280,000, B: $61,000, C: $30,000, PD: $4,400 The value used for fatal crashes in the crash cost is 2 times the value of an 'A' severity crash. See HES documentation for information on when it may be appropriate to use full cost for a fatal crash of $3,600,000. Conclusions: 1. The crash rate for the Lyman Blvd Segment is above the average crash rate and above the critical crash rate based on the Mn/DOT Metro District average crash rates for similar segments. 2. Segments with crash rates above the critical crash rate are considered to be in need of further safety review since there is a high probability (95%) that roadway conditions along the segment are contributing to the crashes and the crashes are not occurring by chance circumstance. 3. The severity rate and crash density for the Lyman Blvd Segment are above the Mn/DOT Metro District average severity rate and crash density for similar segments.

Safety-Related Wetland Impacts and Non Safety-Related Trail Impacts Typically, wetland impacts resulting from safety-related roadway improvements are mitigated through the BWSR Road Replacement Program. Those wetland impacts that result from improvements to address future roadway capacity or recreational trails are not mitigated through the BWSR Road Replacement program; rather, they are often mitigated through the purchase of credits from existing suitable wetland banks or on-site mitigation. In order to separate wetland impacts into relevant categories such as safety, capacity, and, trail- related, SRF created a hypothetical depiction of the subject roadway that would be recommended to address safety related issues, based on estimated 2014 traffic volumes. Based upon previous 2010 traffic counts, historical data and a straight-line estimation method, we estimate the 2014 volumes on CSAH 18 as follows: • West Segment (CSAH 15 to Audubon Road North) – 13,000 ADT • East Segment (Audubon Road North to CSAH 17) – 10,800 ADT Refer to revised Figures 3A-3C in Appendix C. Figures 3A-3C show the revised construction limits for the proposed roadway improvements and a hypothetical minimum build road configuration within those construction limits. Based upon the estimated 2014 traffic volumes, the hypothetical minimum build roadway would consist of a 2-lane (1 lane eastbound and 1 lane westbound) rural section with no median and dedicated left and right turn lanes at the Audubon Road North / CSAH 18 intersection. Refer to Figure 4 in Appendix C for comparison of the hypothetical versus proposed typical sections. The proposed roadway is a 4-lane (2 lanes eastbound and 2 lanes westbound) urban section with a median and dedicated left and right turn lanes. The hypothetical roadway configuration does not include a recreational trail whereas the proposed roadway improvements include a recreational trail. The design of both the minimum build and proposed roadway section, as described above, follow the minimum design standards set forth by Minnesota Rules 8820.9936 URBAN, 8820.9926 RURAL, 8820.9995 BIKEWAY STANDARDS and State Aid requirements. Wetland impacts resulting from the minimum build configuration not associated with trails or capacity improvements would be considered safety impacts to be mitigated through BWSR Program. Wetland impacts outside of the minimum build estimated construction limits resulting from the proposed roadway improvements would be considered non safety-related impacts. Table 1 and 2 below summarize the wetland impacts resulting from the minimum safety-related improvements, the proposed wetland impacts beyond the minimum safety-related improvements and proposed mitigation strategies for each wetland identified along this project.
