BOLTON & MENK Real People, Real Solutions. narrow corridor; our expertise in delineating, protecting, and restoring valuable wetlands; and providing innovative solutions to water quality and flood mitigation. Best Management Practices (BMPs) will be preliminarily designed and analyzed that will: • Incorporate public comments where feasible • Conform to the overall vision of the corridor improvements • Address current drainage issues as documented in the city-wide SWMP • Reduce wetland impacts • Seamlessly integrate with landscape features Our team will prepare a preliminary drainage report that addresses the stormwater management requirements and identifies the likely features needed for compliance as well as the drainage issues or obstacles affecting roadway design. 2.2 Preliminary Noise Assessment Bolton & Menk has partnered with SBP Associates, Inc. (SBP) to complete the noise impact and mitigations assessment that will be required by MnDOT and FHWA as part of the environmental documentation process. We have teamed with SBP on numerous corridor projects to determine the impacts of expansion and develop mitigation strategies that meet the federal requirements. Our team's approach includes: • Monitoring - conduct monitoring at four locations along the project corridor in the morning and afternoon periods. Monitoring periods will be at least 30 minutes in length, and will be conducted consistent with MnDOT and MPCA requirements. • Impact Modeling - modeling the noise impacts of the proposed roadway along the corridor using peak -hour existing and design year traffic conditions. Modeling will be conducted and receptors will be chosen according to MnDOT and FHWA policy. • Mitigation Modeling - for areas exceeding State and/or Federal noise thresholds, SBP will provide an analysis of the cost reasonableness of noise barrier mitigation along the corridor. The analysis will determine whether noise barrier(s) will meet the cost reasonableness requirements and will determine the total estimated cost of the barriers. Barriers meeting the cost - reasonableness requirements must be voted on by the benefitted residents/property owners per MnDOT/FHWA policy. • Noise Assessment Report - a draft and final report will be prepared containing monitoring and modeling results and all analysis consistent with MnDOT/FHWA policy. 2.3 Corridor Beautification Our team will develop a preliminary corridor beautification plan, which will include landscaping and hardscaping for the preferred roadway geometrics incorporating the enhanced treatments chosen by the project partners. Our team will develop construction cost estimates for streetscaping elements. 2.4 Preliminary Design The preliminary design will be a significant task critical to the schedule and final deliverable. The Bolton & Menk team will lead a highly detailed preliminary design effort that will include detailed typical sections, cross sections, construction limits, horizontal and vertical alignments, refined geometric improvements, structure concept design and layout, and drainage improvements. The preliminary design process will result in the layout for the project fully defining the vision. The Trunk Highway portion of the layout will be prepared and undergo the MnDOT staff approval process. IL:
