• Where the available area is tight on the bank, LTD would build in the floodway if there are no other alternatives. LTD understands the regulations and requirements about not constricting the floodway. Areas of concern include just west of Oak Patch and it is very restricted at the HOA near Garfield. • LTD is trying to avoid steep slope areas. • Based on data from the City and the Oregon State Historic Preservation Office (SHPO), there are National Register and SHPO sites within the corridor, however there are no sites located within the Amazon alignment currently under consideration. • Generally, structures 45 years old or older are regulated but LTD is looking at a 50 year window because it takes years to complete the environmental review and LTD wants the Section 106 analysis to be current at the time of the federal decision • Most of the parcels in this area have no construction date data. LTD is currently conducting an inventory to determine potential Section 106 resources and is coordinating with Oregon SHPO. • There is a parcel abutting the area that is owned by the Confederated Tribes of Siletz Indians. • LTD reviewed hazardous materials information from EPA's EnviroMapper web site, which may not include the full range of sites or concerns that would be identified with a hazardous materials investigation of local, state and federal databases. It gives a preliminary review of sites known to EPA and there are a number of sites along the corridor that are listed in EPA's database. Review City's Issues and Opportunities Map • Several City staff reviewed the alignment roll map and identified key issues and recommendations. However, it is important to note there was no review by other City personnel and this is not a City recommendation. • Two key elements considered are Natural Resources Values and Recreational Values. • Removing the bike path at the east end, results in a loss of the entire creek corridor recreational experience. • City would prefer expanded habitat / visual amenity experience in the EmX facility. For example, where EmX is close to the top of bank include a visually effective buffer of native plants, maybe 20- 25ft. Use native trees and shrubs for drier sites • This buffer would screen EmX from users and could also integrate shading required by the city code. Important to have both high and low canopy features along the entire creek • Along the north side of Berkeley Park there are some opportunities. • LTD could add the "missing link" to Berkeley Park or acquire "missing link" to nearby wetlands. • Past Acorn Park Street, LTD could build a pedestrian / bike bridge near the low- income housing project. • Do not know if Richardson Bridge be moved; it might be a historic bridge. • The City needs solutions where bikes and pedestrians cross the EmX line. • The EmX alignment needs to be as straight as possible, because curvier alignments slow the system. • The Rexius area provides enhancement opportunities to widen the channel, install plantings and shading, and build parklands. These improvements would need to occur with the alignment. • The wetlands area west of Rexius provides a mitigation opportunity for wetlands affected by 13th extension alignment. Parks staff prefer 13th extension alignment over alignment closer to Channel. West Eugene EmX Extension DEIS Amazon Alignment 02.20.09 Work Session Meeting Notes 3.5.09 IP 3
