Slaffwill be having Ihe City's Floodplain Manager review the proposal for general comments. Although this is a funding issue and nol necessarily a completeness review issue,statTunderstood that the bridge replacemenl project was in Ihe STlP and the MTIP bul not inthe RTP as staled on page 16, Additionally, although this is not stated in the written statemenl, staff previously understood from ODOT's anorney Ihaltheir opinion is thaI bridge replacemcnt projecls do not need to'be included in TransPlan, oregon bridge delivery partners Response' Melro Plan policies C 30 and C 3 I are addressed in an attach~ent to this letter. In response to this comment, ODOT will be providing theC"ity with an errata sheet that does two things. First,it wjll amend the section concerning consistency with the RTP, explaining the source of Ihe funding for the project and clarifying that the funds arc specially, eannarked for the purpose of this bridge replacement project (i:e., the funds can only be used for this bridge replacement purpose), With the projecl'in the MTIP; this -is sufficient to meet FHW A requirements: Second, it will remove references to projects 150 and 260 to show consistency with TransPlan (because those projects arc placeholder capacity increasing projects) and insteadrely upon TrnnsPlan itself tor consistency, . since TransPlan shows ~n .I-~ connection over the Willamette River and'failure to repair the bridge,would be inconsistent with TransPlan. The errata sheel will address cQnsistcncy'.with TransPlan policies that' address the importanccofl-5 and a connection over the Willamelle River. Date Received l' i , I , 1165 Union StreelNE Salem.

Environmental Resources Element Natural Hazards (Goal 7) Policy C.30 Except as otherwise allowed according to Federal Emergency Management Agency (FEMA) regulations, development shall be prohibited in jloodways if it could result in an increased jlood level. The floodway is the channeL of a river or other water course and the adjacent land area that must be reserved to discharge a one-percent- chance jlood in any given year, The 1-5 Willanlette River Bridge is located within a FEMA designated regulatory floodway and floodplain, Therefore, the design of the replacement bridge must satisfy the regulations set forth in the National. Flood Insurance Program (NFIP). The NFIP requires that any modifications that cause a rise in the Base Flood Elevations (BFEs, which corresponds to water surface elevations associated with the IOO-year flood event) must be approved by FEMA. The proposed structure satisfies the requirements of the NFIP, The, no-rise condition is also a requirement ofODOT for any bridge replacement project. Two pier location scenarios are currently under consideration (Proposed Option A and Proposed Option B). Based on the modeling, Option A would result in an increase of 0.02 feet over existing conditions for the lOO"year flood event. Option B would result in a decrease of 0.54 feet for the 1 OO-year flood event. For the Environmental Assessment, the hydraulic conditions of the 1-5 Willanlette River Bridge Project were analyzed using the U.S. Army Corp of Engineers' HEC-RAS model. Natural, existing and proposed conditions (with pier locations Options A- and B) were . . .' modeled. Conservative assumptions regarding pier size were used for this modeling. Refined design of the concepts and further hydraulic analysis will allow confirmation that the proposed project will result in no rise of the base flood elevation. A FEMA "no-rise" certification will be obtained from the City of Eugene for any construction or structures within flood ways/special flood hazard areas within Eugene. Policy C,31 When development is allowed to occur in the jloodway or jloodway fringe, local regulations shall control such development in order to minimize the potential, danger to Life and property, Within the UGB, development should result in in1illing of partially developed land Outside the UGB, areas affected by thejloodway andjloodway fringe shall be protected for their agricultural and sand and gravel resource values, .their open space and recreational potential, and their value to water resources, The proposed replacement bridges are located within the Eugene-Springfield UGB. Portions of the project area consist of developed urban lands and portions of the project area consist of non-urban areas. Both Eugene and Springfield have adopted ordinances oregon bridge delivery pa,rtners Date Received ' 1165 Union Street NE Salem, OR 97301 , FEB 15 2008 ,Page 1, of 2 t c:.~' ,;. " t~ I....' Planner: BJ regulating construction within floodplains and floodways. The following pennits will be obtained under these ordinances to allow development in the floodway or floodplain. . A,Site Development Permit (or similar building pennit), and a FEMA "no-rise" certification will be obtained from the City of Eugene for any construction or structures within floodways/special flood hazard areas within Eugene. . A Type 1 pennit will be obtained from the City of Springfield to allow any construction in the floodplains or floodways within Springfield. Development in relation to the project is in the nature of a replacement 1-5 bridge over the Willamette River. The project will comply with approval conditions imposed during the pennitting process.
