Additional public water main construction will be necessary to serve the proposed development, specifically in the zone between Ferry Lane and High Street. In general, the existing looped water main within the Riverfront property does not present major conflicts with the proposed block layout. However, there are several areas where relocation or reconstruction will be required. The proposed block layout at the east side of the intersection of Millrace Lane and Railroad Street conflicts with the existing 8 -inch main that follows the proposed Ferry Lane alignment. In addition, the water mains may require reconstruction at the proposed Millpond Swale crossing and 5th Avenue Extension Swale. It should also be noted that an existing 42 -inch EWEB transmission main enters the property at the northeast terminus of the proposed Water Lane, extends in a southwesterly direction to the intersection of Water Lane and the proposed Railroad Street, and then extends to the northwest parallel to the railroad tracks. Basin designations are taken from the 2002 City of Eugene Stormwater Basin Master Plan (SBMP). "Based on the OBEC Consulting Engineers Topographic Survey dated June 13, 2011. The existing minor sub - basins within the EWEB Riverfront Property include WS -100, MR -010, and SW -110. Reference Figure 3 -5 of the 2002 SBMP.
