-242-- M~VDOT AD'cement No. 89336 Exhibit A Detailed Scope of Work and Deliverables noise. State employs a guideline of 5 dBA. That is, unless the proposed wail can result in a reduction of at least $ dBA at the receptor, it is not pursued. The consultant will prepare thc no-build and final layout build Air Quality Analysis for T.I4. 47 (one hour average and eight hour average) using the Mobile 5A Emissions Model (or most current emissions model) and tbe CAL3QHC dispersion model. A prelim/nary drainage analysis will be conducted for the T.H. 47 project. Evaluations will/nclnde, but not be lhnited to: location and size of principal culverts and storm sewers; ~vater quality consideration; pending locations; flood plain impacts and wetland delineation. The wetland delineation will include estimated impacts to thc wetlands for the various roadway options and identification of the potential mitigation sites. The drainage analysis will be coordinated xvith state and local agencies having either jmisdictional or review aotl~odty over the final drainage desigq~ and will be cIosely coordinated with the State's Metro Water Resources Engine.:ring Office. Field visits with those agencies will also be conducted. Flow direction, high poim and low point locations, pond locations including which areas are treated by each pond, wedand delineation and mitigation locations, flood plain impacts and downstream water bodies receiving runoff fi'om these roadways will be shown in relation to the final proposed roadway alignments. All proposed fi~ture drainage systems (cnlverts, ponds and dowa~stream tailwaters) will be desigmcd using the con-idor cities comprehensive zoning plans and assuming 100% developed couditions. A cost benefit analysis will be included. '['he analysis will compare the no-build to the T.H. 47 preferred alternative build conditions for years 2010 and 2030. The consultant will also prepare the Minnesota Deparlment of Natural Resources (DNR) Qnestionnaim. Copies of the Draft EAW will be available for viewing at an initial Public Infonnation Meeting. The Final ]:.AW will include connnents on the Draft EAW from thc agencies involved and the public and the responses provided to those comments. Copies of the Final EAW will be available for viewing at the subsequent Public Infommtion Meeting. The EAW will be prepared in the most current version of Microsoft Word. One final elect-runic copy of the EAW will he provided to State. Final hard copies will be distributed as £olI0ws: Anoka Connty (5 copies), State (17 copies), the City of Anoka (3 copies), City of Ramsey (3 copies) and Bm-ns Township (3 copies). Approximately 25 copies of the Dra/'r EAW for prelim/nary review will be provided as requested. Thc consultant will prepare the Findings of Fact and Conclusion and the request to the Federal Highway Administration (FHWA) for thc Finding of No Significant Impacts (FONSI) leading to the Negative Deelaration. 2. Concept Layonts and Geometric Layont Preparation (Including Profiles~ Typical Seetions and Cross-Sections) An aoalysis of traffic opera/ions for three concepts within the projects limits ~vill be completed with recommendations of geomeu'ics including, but not limited to: mm lanes, channclizatiopJmedian breaks, access closures and fi'enrage roads resnltmg in a Level I geometric layout of tho preferred alternative that ca:~ be utilized tt~roughout the public involvement process. The concept analysis will include possible signal locations, stormwater pending locations, noise wall locations, frontage road locations, access modifications and, if ncecssary, wetland mitigation and Page 2 of 7
