Proposed wetland impacts as indicated in Figure 3A from application The proposed wetland impacts resulting from the roadway improvements are divided into two categories: safety -driven impacts (impacts that result from the roadway construction and creation of the stormwater ponds) (.33 acres), and non -safety related impacts (impacts resulting from trail creation and other non - safety roadway improvements including increased capacity) (1.55 acres). Safety- related wetland impacts are eligible to be replaced using credits from the Board of Water and Soil Resources (BWSR) roadway replacement bank. Because the impacts for this portion of the proposed project are eligible for BWSR replacement credits, the required replacement ratio for the roadway and stormwater pond impacts are 2:1. Thus, .66 acres will be withdrawn from the BWSR Road Replacement Bank. The additional 1.55 acres of wetland impact associated with the multi -use recreational trail and non - safety related and increased capacity impacts will be mitigated for using wetland bank credits purchased by the County from account #1392. This wetland bank is located in the same Bank Service Area (BSA 9) and Major Watershed (33- Minnesota) as the proposed project. Therefore, the impacts are required to be mitigated for at a 2:1 ratio, resulting in the purchase of 3.1 acres of wetland credit from bank #1392.

The plans call for a cut of up to eight (8) feet at a point north of the wetland boundary. This is approximately four (4) feet below the elevation of the wetland bottom (see Figure 5 below). If it cannot be shown that the remnant portion of this wetland is viable, additional mitigation will be required for the secondary impacts associated with the road. The consulting engineer for Carver County is has evaluatinged this and will has provided a follow - up addendum. This addendum has net been reeeived at the ti-°l° included in the appendices of this staff report. Figure 5. Cross Section at wetland IA BACKGROUND 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. Due to the current and expected future population growth, congestion in areas of central and eastern Carver Country is expected to rise on county facilities, occurring frequently during peak traffic hours. The Lyman Boulevard (CSAH 18) Roadway Improvements Project was deemed necessary in order to ease projected congestion, improve safety, and address future traffic growth. The need for the project is also identified in the Carver County Transportation Plan (2007). Fed, Prof. - BLYMAN 21.:2..... rtEB vywiW I :r. Existing - Grade Rrrr .

The Lyman Boulevard (CSAH 18) Roadway Improvements Project was deemed necessary in order to ease projected congestion, improve safety, and address future traffic growth. The need for the project is also identified in the Carver County Transportation Plan (2007). Lyman Boulevard (CSAH 18) Roadway Improvement Project Wetland Alteration Permit Planning Case #2014 -05 March 24, 2014 Page 9 of 19 DISCUSSION The Lyman Boulevard (CSAH 18) Roadway Improvements Project involves reconstruction of the segment of Lyman Boulevard (CSAH 18) from approximately 800 feet east of Audubon Road (CSAH 15) to approximately 700 feet east of Powers Boulevard (CSAH 17), within the City of Chanhassen. The proposed project will accommodate capacity and safety improvements by reconstructing the current roadway from a two -lane undivided highway to a four -lane divided highway with medians and designated left turn lanes. The presence of the proposed medians will reduce the potential for head -on vehicle collisions. Additional crash data and safety information can be found in Appendix E and F of the Supplemental Information for the WCA/ Corps Joint Permit Application, dated January 13, 2014. Other proposed safety improvements include improving sight lines by flattening grades and relocating dangerous approaches, as well as creating dedicated left turn lanes from eastbound Lyman Boulevard to northbound Audubon Road, an additional left turn lane from northbound Powers Boulevard to westbound Lyman Boulevard to accommodate increased traffic levels resulting from the new Chanhassen High School, and at the reconstructed intersection of Sunset Trail and Lyman Boulevard. A pork chop island is also proposed in the southwest quadrant of the intersection of Lyman Boulevard and Powers Boulevard 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 pork chop island will also serve to channelize heavy vehicular traffic turning from eastbound Lyman Boulevard to southbound Powers Boulevard. This channelization and the dedicated right turn lanes will decrease the potential for rear end crashes which result from conflicts between turning traffic and through traffic. Wetlands within the proposed project area were delineated in August of 2007 and approved by the City of Chanhassen. An e -mail chain (2010) appended to the WCA/ Corps Joint Permit Application approved the use of the Wetland Delineation Report, dated August 2007, completed by Barbara Walther of SRF Consulting Group (Appendix D of the WCA/ Corps Joint Permit Application, dated October 23, 2012), for the Lyman Boulevard reconstruction. In 2013 the wetland delineation was updated by SRF Consulting Group Inc. and Houston Engineering Inc. Both boundary and type application updates were approved. The delineation identified 18 wetland areas within the proposed project areas, as well as Bluff Creek. The original Joint Permit Application was submitted in December of 2012. The current application and supplemental information has been submitted in order to clarify and respond to ongoing discussions since the original submittal. The proposed improvements will result in permanent impacts to five wetlands including a small area peripheral to Bluff Creek, described and shown as follows: Wetlands I and 113: These wetlands were identified as wetland W -17 in the original SRF report but were re- delineated for a third time by Houston Engineering where they were identified as wetland 1A and 113. They were found to be historically one wetland basin, and are now separated by a constructed berm. Both are classified as Manage 2 wetlands under the city's wetland classification system. Wetland lA is classified as a Type 3, Shallow Marsh wetland according to Fish and Wildlife Service Circular 39. Wetland 1B is classified as a Type 2, Lyman Boulevard (CSAH 18) Roadway Improvement Project Wetland Alteration Permit Planning Case #2014 -05 March 24, 2014 Page 10 of 19 Fresh (wet) Meadow according to Fish and Wildlife Service Circular 39. Wetland lA and 1B are located immediately south of Lyman Blvd within the right -of -way at 1551 Lyman Boulevard. The proposed permanent impact to Wetland IA will be approximately .Q 0. 14 acre, and the proposed impact to Wetland 1B will be approximately .06 acre (see aerial photograph in Figure 6 below). Wetland 2: This wetland was identified as W -15 and W -16 in the original SRF report but became wetland 2 when Houston re- delineated the basin. This wetland is classified as a Manage 2 wetland under the city's wetland classification system. It is classified as wetlands Type 2, Fresh (Wet) Meadow according to Fish and Wildlife Service Circular 39. Wetland 16 is located immediately south of Lyman Boulevard (CSAH 18), and east of Bluff Creek. This wetland is a tributary wetland to Bluff Creek. The predominant vegetation species in the impacted area are Reed canary grass (Phalaris arundinacea), Cattails (Typha angustifolia), and Willow species (Salix spp.). The proposed impact area in this wetland is approximately .8 acres (see aerial photograph in Figure 7 below). Lyman Boulevard (CSAH Planning Case #2014 -05 March 24, 2014 Page 11 of 19 18) Roadway Improvement Project Wetland Alteration Permit Wetland 14: This wetland is classified as a Manage 2 wetland under the city's wetland classification system, and a Type 2, Fresh (wet) Meadow according to Fish and Wildlife Service Circular 39. It is a flow - through wetland, located north and east of the intersection of Audubon Road (CSAH 15) and Lyman Boulevard (CSAH 18), which receives water from, and outlets to, Bluff Creek. The predominant vegetation in the impacted area is Reed Canary Grass (Phalaris arundinacea), green bulrush (Scirpus atrovirens), and Sedge species (Carex spp.). The proposed permanent impact to this wetland will be approximately .94 acres (see aerial photograph in Figure 8 below). Wetland 19: This wetland is classified as a Type 1L, Seasonally Flooded Basin wetland according to Fish and Wildlife Service Circular 39. It is not classified under the city's wetland classification system. Wetland 19 is located immediately southeast of the intersection of Lyman Boulevard (CSAH 18), and Powers Boulevard (CSAH 17). The predominant vegetation species in the impacted area is Green Ash (Fraxinus pennsylvanica).The proposed impact area to this wetland is approximately .01 acres (see aerial photograph in Figure 9 below). Lyman Boulevard (CSAH 18) Roadway Improvement Project Wetland Alteration Permit Planning Case #2014 -05 March 24, 2014 Page 12 of 19 Bluff Creek: Bluff Creek is a Minnesota Department of Natural Resources Protected Watercourse. The predominant vegetative species in the impacted area is Reed Canary Grass (Phalaris arundinacea). The applicant is proposing .17 acres of permanent impact to Bluff Creek, associated with culvert replacement, grading, and rip -rap to be installed with the culvert. The applicant has obtained the necessary permits and approvals from the Minnesota Department of Natural Resources for the proposed work within Bluff Creek (Department of Natural Resources Public Waters Work Permit 2014 -0526 can be found in Appendix D of the Supplemental Information for the WCAI Corps Joint Permit Application, dated January 13, 2014). ALTERNATIVES The Wetland Conservation Act requires the applicant to list at least two alternatives to the proposed project that would avoid or minimize impacts to wetlands or waters; one of which may be "no build" or "do nothing ". The applicant then must list and explain why the option described in the application was chosen over these alternatives. The following alternatives were presented in the Joint Notification Application submitted by the applicant: A No -Build alternative would entail making no changes or improvements to the existing roadway, and would result in no impacts to wetlands. Maximum capacity, and the associated safety issues, could be reached within only a few years at the current rate of growth within the vicinity of the proposed project. The traffic forecasted for 2034 indicates 26,500 vehicles per day (vpd) in the project area. This alternative does not feasibly meet the proposed project goals of safety improvement and congestion ease within the corridor. The No -Build alternative does not address the purpose and need for the project. Lyman Boulevard (CSAH 18) Roadway Improvement Project Wetland Alteration Permit Planning Case #2014 -05 March 24, 2014 Page 13 of 19 Alternative road alignments were evaluated to determine if impacts to the wetlands and Bluff Creek could be avoided and to identify minimization opportunities. Wetlands to be impacted as a result of the proposed project are located within the right -of -way, near or at the toe -of -slope of the existing roadway. Bluff Creek also flows under the existing Lyman Boulevard (CSAH 18) corridor, thus complete avoidance is not feasible. Trail Alternative 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 influenced trail location. Impact Minimization The Wetland Conservation Act requires that if avoidance is not an option, the unavoidable impacts are minimized to the greatest extent practicable. Efforts have also been made by the applicant to minimize the proposed wetland impacts by creating steeper side slopes through the highway sections that are adjacent to wetlands, thereby minimizing the roadway footprint through these areas. The multi -use trail was designed to minimize wetland impacts to the greatest extent practicable without compromising project goals. Stormwater Management Stormwater runoff from the newly created impervious surface associated with the western portion of the project will be treated utilizing the Bluff Creek stormwater pond located immediately southeast of the intersection of Audubon Road (CSAH 15) and Lyman Boulevard (CSAH 18), which was constructed in previous phases of the Lyman Boulevard reconstruction. Runoff in the eastern portion of the project area will connect to an existing stormwater pipe that drains to an existing stone pond east of Powers Boulevard. Therefore, there will be no additional wetland impact due to creation of stormwater management facilities. Wetland Replacement Wetland replacement for this project will be accomplished via a number of methods; restoration for temporary impacts, BWSR roadway replacement bank, and wetland bank credits purchased from wetland bank #1392. The revised replacement plan proposes that .66 acres (.33 ac at a 2:1 ratio) resulting from the roadway safety improvements would be replaced with BWSR roadway replacement credits, and 3.1 acres (1.55 ac at a 2:1 ratio) resulting from non - safety - related wetland impacts be replaced by the County, using wetland bank credits purchased from wetland bank account #1392, located in the same Bank Service Area 9, and Major Watershed 33. Lyman Boulevard (CSAH 18) Roadway Improvement Project Wetland Alteration Permit Planning Case #2014 -05 March 24, 2014 Page 14 of 19 A total of. 14 acres of temporary impacts will be made in areas where wetlands are immediately adjacent to the existing roadway toe -of- slope, due to muck removal and soil stabilization. These temporary impacts will be restored to preconstruction conditions by re- grading to original contours, and stabilized with a combination of Types 1, 2, and 3 Rapid Stabilization methods. OTHER AGENCIES The applicant is responsible for obtaining any permits or approvals from the appropriate regulatory agencies and compliance with their conditions of approval. FINDINGS The Planning Commission shall recommend a wetland alteration permit and the Council shall issue such wetland alteration permit only if it finds that: a. The proposed project will not be detrimental to or endanger the public health, safety, comfort, convenience or general welfare of the neighborhood or the city. FINDING: The proposed wetland impacts that will occur with the Lyman Boulevard (CSAH 18) Roadway Improvements Project have not been found to pose danger to public health, safety, comfort, convenience or general welfare. The goal of the proposed project is to address existing safety deficiencies and to provide for the present and future traffic needs of the area, improving safety and convenience for residents and recreationalists. b. The proposed project will be consistent with the objectives of the city's Comprehensive Plan and the zoning chapter of the City Code. FINDING: The proposal is consistent with the objectives of the city's Comprehensive Plan and City Code. It complies with all city, state and federal requirements. The proposed roadway improvements and trail construction is shown in the City's Future Park & Recreation Initiatives map and are consistent with City and regional trail plans. The roadway improvements and trail construction will improve safety and ease congestion within the project area. c. The proposed project will be designed, constructed, operated and maintained so to be compatible in appearance with the existing or intended character of the general vicinity and will not change the essential character of that area. FINDING: The appearance and character of the general vicinity will not change.

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 G. 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 Imorovements 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 Wedand Icipacts 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 wedand 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 Q. 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 Lyman Blvd Corridor Segment Crash Rate Data Mn /DOT Crash Rates Metro Rural 2 -Lone* 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. tr Crash Detail Report CAB CSAH 18 8 Audubon Rd Sol 043450198 10/15/2004 1935 County:Carver City:CHANHASSEN Severity: PROPERTY DAMAGE - NO Roadway Type:2 LANES - -1 EACH WAY Type of Crash:OTHER TYPE OF COLLISION Surface Conditions: WET Light Conditions: DARK - STREET LIGHTS ON Weather Cord 1:RAIN Weather Cord 2:RAIN Number of Vehicles:02 Init Trav Dir.

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 wedand 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.

The roadway here is currently a rural, undivided two -lane section. Reconstruction will upgrade the roadway to a divided four -lane section. West of CSAH 15, CSAH 18 has already been upgraded to a divided four -lane section. There will be minor horizontal and vertical adjustments to the roadway. Work will include the widening of traffic lanes and construction of a two -way ped/bike trail along the north side of CSAH 18. Narrow strips of additional right of way will be needed for the project. The project area of potential effect (APE) for direct effects to cultural resources is defined by the project construction limits, including temporary and permanent easements. The APE for indirect effects includes the first tier of properties adjacent to the project that are not screened from the project by vegetation, topography or other features. There are no known cultural resources within the APE. The APE has low potential for containing unidentified intact archaeological resources due to disturbance caused by previous roadway and utilities construction. The architecture/history properties within the APE are less than 50 years of age and are not eligible for the National Register of Historic Places. The finding of this office is that there will be no historic properties affected by the project as currently proposed. If the project scope changes, please provide our office with the revised information and we will conduct an additional review. Sincerely, Elizabeth J.

To: Terrance Jeffery, Water Resources Coordinator City of Chanhassen From: Matthew Meyer, Senior Environmental Scientist Nathen Will, Senior Associate Date: February 26, 2014 Subject: CSAH 18 (Lyman Boulevard) Phase 3 Wetland Permitting Update for Wetland lA Introduction Memorandum SRF No. 0076098 3040 This memorandum transmits updated information and attachments to address the Technical Evaluation Panel's (I'EP) comments related to the secondary impacts associated with Wetland IA, and to provide supportive evidence for the maintenance of hydrology, including the avoidance of secondary impacts to the remaining project wedands. Wetland 1A Secondary Impacts As part of this project, the existing CSAH 18 roadway profile is being lowered approximately 6 feet to improve sightlines and safety at the intersection of Sunset Trail which includes the private driveway adjacent to Wetlands W -lA and W -113. This profile adjustment is reflected in the attached cross sections, which show the proposed grading along entire CSAH 18 project Refer to cross sections from Station 216 +50 to Station 217 +50 (Plan Sheets 204 and 205 — Appendix B) for the proposed grading impacts and driveway profile as compared to the existing ground line. The proposed grade changes associated with the driveway approach at Station 216 +70 RT (eastbound CSAH 18) has the potential to reduce hydrology to the remaining 0.12 acres of Wetland W -1A; creating a secondary impact. As a result of grade changes on the south -side of Wetland W- 1A, the basin is considered to be impacted in entirety due to hydrology alterations that will likely drain the remaining portion of Wetland W -lA. Impacts have been revised in Table 1 (below). The additional mitigation is not necessitated by safety, and will be purchased from wetland bank number 1392 by Carver County. Hydrologic Maintenance of Project Wetlands Wetland 2 — The existing hydrology will be maintained to this wetland by perpetuating flow from the existing drainage area north of CSAH 18 and west of Sunset Trail under CSAH 18 through a cross culvert pipe at Station 209 +60 constructed to match the existing culvert invert elevations. Surface flow to this wetland will continue from the adjacent farm field south of CSAH 18. Wetlands W -14, Bluff Creek and W -19 — The existing hydrology at these wetlands will be mostly unaffected by the project other than the proposed fill needed to construct the roadway which is impacting the wetlands. Refer to the attached construction plan sheets and cross sections for grading impacts. www.srfconsulting.com One Carlson Parkway North, Suite 150 1 Minneapolis, MN 554474443 1 763.475.01110 Fax; 763.475.2429 An Eguul Opportunity Engrloyer Table 1: Revised Wetland Impacts Wetland ID, 1/4 Type: Total Permanent Temporary Topographic 1/4 Sec.

The following comments should be included in a revised mitigation plan: 1) Wetland 1A should be noted as fully impacted and included in the mitigation plan since the wetland will be drained with the proposed street and storm sewer improvement project. This has been previously discussed at the Technical Evaluation Panel meeting on February 19, 2014. a. Action required: Revise the wetland permit to fully impact wetland 1A and include in the mitigation requirements. 2) The Lyman Boulevard construction documents show a 24" culvert crossing (near plan Station 209 +50) that conveys water from the north side of Lyman Boulevard to the south side where the PPB Holdings property is located. Public water that will be conveyed through the 24" culvert will discharge on private property without an easement or a defined ditch at a minimum 1% slope to convey the water toward Bluff Creek along the south side of Lyman Boulevard. The construction plans should be revised to connect this flow of water to the Lyman Boulevard storm sewer system rather than discharging the water on private property. Alternativety, the water could be conveyed in a pipe to the northwest corner of the PPB Holding property and discharged to the ditch located west of the PPB Holdings property. If the current plan were constructed with the 24" culvert in the current location, without a defined ditch, the project would have a negative impact on the PPB Holdings property and cause potential flooding on the PPB property. There will potentially be more water discharging through a 24" pipe rather than the existing 18" culvert crossing, as well the original roadway culvert was only a 15" culvert. The proposed toe of scope elevation is also 0.5 to 1.0 ft. higher than the existing road toe of scope, this will as well negatively impact the PPB Holdings property with potential flooding in the area. a. Action required: Revise the 24" culvert crossing eliminating the discharge of public water on private property. Page 2 of 2 3) The mitigation plan does not identify the complete wetland impact area in the area of Wetland n2 for the construction project. Along the north line of the PPB Holdings property, the impact area aligns with the toe of slope for the proposed roadway. The impact area needs to be expanded to account for the full area of wetland impact that results from the grading operations that will occur beyond the toe of slope where a ditch will be needed to convey the water. A ditch cross section, similar to the ditch shown from 206 +50 and 207 +00, is required to convey the flow to the west toward Bluff Creek. The current plan does not show the ditch with a minimum 1% ditch slope to convey the water from the PPB Holdings property to Bluff Creek. a. Action required: Revise the mitigation plan to show the complete wetland impact area required for grading to construct at ditch at the toe of slope with a minimum 1% slope. The easement area needs to be revised to accommodate the grading of the ditch to provide positive drainage from the PPB Holdings property. Thank you for the opportunity to comment on the impact/mitigation plan. We look forward to reviewing the revised plan that addresses our comments.

The center of the access should be approximately 50 ft. from the northwest corner of the PPB parcel. Response Upon discussion with the City of Chanhassen, the City is willing to permit the right in /right out future access and construction of the right turn lane upon completion of the City permitting /review process. The cost for the permitting /review process and turn lane construction would be borne by the property owner /developer. The County will not be generating turn lane cross section information until the application process is started and the location of the right turn lane is more defined. 2) Eliminate the 24" culvert crossing near the northwest corner of the PPB property so that additional permanent easement is not required to convey the public water across the PPB property. As we discussed, the pipe alignment draining water from the north side of Lyman Boulevard should be connected to the Lyman Boulevard storm sewer system. Response Upon further discussion with the City of Chanhassen it was determined that the centerline culvert provides runoff water to the potential wetland to the south. We cannot divert this water as part of this project. We are reviewing the need for additional permanent drainage easement as part of the County project to accommodate this culvert outlet drainage to the west. We also reviewed the storm sewer design calculations. The storm sewer pipe and the stormwater pond as designed cannot accommodate this additional drainage without a complete redesign and re- permitting of the western 700 feet of the storm sewer pipe and storm water pond. 3) The swale at the toe of slope on the south side of Lyman Boulevard on the PPB property must be at the same elevation as the existing swale so that existing drainage patterns are maintained from the PPB property. Response Positive surface water flow to the west will be maintained as part of the County Road 18 construction. 4) The wetland mitigation plan should be updated to reflect the draining and impact of wetland 1A. Response The County is submitting a revision to our wetland mitigation permit that provides for mitigation of all of wetland W -1A. 5) The plan should be revised to fully impact the residual sliver of Wetland 2 area on PPB property so the future street connection to the right in /out can be constructed without impacting wetland areas. See Exhibit A. Response The County wetland permit application does not include any additional mitigation in wetland W -2. See response No. 1. At our January 31St meeting you had a question about the run -off on the east side of the project past the Fox property. Upon review of the construction plan it was confirmed that storm water that goes east past the Fox property outlets into the storm sewer system on Lyman Blvd east of Powers Blvd. This storm sewer system outlets to a storm water pond further east that was built as part of the TH 212 DB project. The original design of this storm water pond included adequate sizing for additional future runoff considerations. The storm water pond will accommodate this additional runoff. We have taken bids on the County Road 18 project and are in the process of reviewing and awarding the project. Construction is scheduled to begin on April 15th. Work by Mr. Dorsey's property could begin in early May. If a plan for a right turn lane and right in/ right out entrance is developed, we will try to accommodate that turn lane project into our County Road 18 construction project if we are able.

The center of the access should be approximately 50 ft. from the northwest corner of the PPB parcel. 2) Eliminate the 24" culvert crossing near the northwest corner of the PPB property so that additional permanent easement is not required to convey the public water across the PPB property. As we discussed, the pipe alignment draining water from the north side of Lyman Boulevard should be connected to the Lyman Boulevard storm sewer system. 3) The Swale at the toe of slope on the south side of Lyman Boulevard on the PPB property must be at the same elevation as the existing swale so that existing drainage patterns are maintained from the PPB property. 4) The wetland mitigation plan should be updated to reflect the draining and impact of wetland 1A. 5) The plan should be revised to fully impact the residual sliver of Wetland 2 area on PPB property so the future street connection to the right in /out can be constructed without impacting wetland areas. See Exhibit A. Page 2 of 2 PPB Holding LP agrees to pay the costs associated with the right turn lane and right in /out access based on the unit bid prices for the appropriate construction items related to the access construction. We realize the project bid documents have been prepared, and so we request a separate supplemental agreement be prepared for the access construction. Please let me know if you have any questions. We would like you implement our requests in a timely manner so they can be efficiently included in the construction project. Sincerely, °'` Mark Anderson, PE MFRA, Inc.

This letter is in Phone: 952.2271120 response to those comments. Fax: 952.227.1110 1) Wetland IA should be noted as fully impacted and included in the mitigation plan Recreation Center since the wetland will be drained with the proposed street and storm sewer 2310 Coulter Boulevard improvement project. This has been previously discussed at the Technical Phone: 952.227.1400 Evaluation Panel (TEP) meeting on February 19, 2014. Fax: 952.227.1404 Planning & R: On February 26, 2014, SRF submitted a memorandum of revision to Natural Resources their January submittal. This revision included the full impact of Phone: 952.2271130 wetland 1A as identified in the Houston Engineering delineation report Fax: 952.227.1110 and commensurate mitigation. This update was emailed to your client Mr. Rick Dorsey of PPB Holdings on February 26, 2014 at 1:56 PM via Public Works email. 7901 Park Place Phone: 9522271300 2) The Lyman Boulevard construction documents show a 24" culvert crossing (near Fax: 952.227.1310 plan Station 209 +50 that conveys water from the north side of p ) y Lyman Boulevard Senior Center to the south side where the PPB Holdings property is located. Public water that Phone: 952.227.1125 will be conveyed through the 24" culvert will discharge on private property Fax: 952.227.1110 without an easement or a defined ditch at a minimum I% slope to convey the water toward Bluff Creek along the south side of Lyman Boulevard. The Web Site construction plans should be revised to connect this flow of water to the Lyman www.ci.chanhassen.mn.us Boulevard storm sewer system rather than discharging the water on private property. Alternatively, the water could be conveyed in a pipe to the northwest Chanhassen is a Community for Life . Providing forToday and Planning forTomorrow Lyman Boulevard Wetland Mitigation Plan PPB Holdings March 5, 2014 Page 2 corner of the PPB Holding property and discharged to the ditch located west of the PPB Holdings property. If the current plan were constructed with the 24" culvert in the current location, without a defined ditch, the project would have a negative impact on the PPB Holdings property and cause potential flooding on the PPB property. There will potentially be more water discharging through a 24" pipe rather than the existing 18" culvert crossing, as well the original roadway culvert was only a 15" culvert. The proposed toe of slope elevation is also 0.5 to 1.0 ft. higher than the existing road toe of slope, this will as well negatively impact the PPB Holdings property with potential flooding in the area. R: The County adequately addressed this concern in their response letter dated February 25, 2014. This is a design issue and is outside of the purview of the Wetland Conservation Act and the City administered Wetland Alteration Permit. 3) The mitigation plan does not identify the complete wetland impact area in the area of Wetland #2 for the construction project. Along the north line of the PPB Holders property, the impact area aligns with the toe of slope for the proposed roadway. The impact area needs to be expanded to account for the full area of wetland impact that results from the grading operations that will occur beyond the toe of slope where a ditch will be needed to convey the water. A ditch cross section, similar to the ditch shown from 206 +50 and 207 +00, is required to convey the flow to the west toward Bluff Creek. The current plan does not show the ditch with a minimum 1 % ditch slope to convey the water from the PPB Holdings property to Bluff Creek. R: The objective of the MN Wetland Conservation Act and Chanhassen Wetland Protection as indicated in Section 20 -403 of the Chanhassen City Code is to achieve no net loss of wetland. There is no compelling sequencing argument for additional wetland impacts that has been offered. The applicant has made efforts to minimize wetland impacts to the greatest extent practicable. If additional impacts are proposed by the County for any reason, those impacts and the subsequent replacement plan will be reviewed and judged on their own merits.
