means (pipe, open drainage system, drywell), nor do they preclude conveyance by any particular means. The water quality provisions of the ordinance include pollution reduction, flow controls for headwater sites, oil controls, and source controls (Sections 9.6792 through 9.6795). These are new requirements for development in Eugene and are being implemented in direct response to the new Basin Plans and the City’s National Pollution Discharge Elimination System (NPDES) permit that requires the establishment of “controls to reduce the discharge of pollutants to the municipal stormwater system from areas of new development and significant redevelopment.” The water quality provisions of the ordinance do not dictate the type of water quality facilities that must be used, but provides the basic design standard that must be met and references the Stormwater Management Manual for detailed design requirements. River Road - Santa Clara Basin Plan Status In April 2004, the City of Eugene and Lane County entered into an agreement for stormwater services, including collaborating to complete the draft River Road - Santa Clara Basin Plan. Work to finalize the plan is underway, involving City of Eugene and Lane County staff and consultants, and the plan is scheduled for completion by December 2006. The final plan will include a stormwater management strategy for the River Road – Santa Clara basin, including capital projects and development standards. Relationship of River Road - Santa Clara Basin Plan to Stormwater Development Standards The proposed stormwater development standards ordinance and the River Road - Santa Clara Stormwater Basin Plan are complimentary but independent of each other. Given the in-depth analysis and comparison of options for addressing runoff from new development that was done in the earlier basin planning process, the consistent outcome for all of the other six basins, and the benefits of applying consistent stormwater quality development standards city-wide, additional analysis on that point is not a part of the current work plan. The draft River Road - Santa Clara Basin Plan reflects that implementing on-site stormwater development standards city-wide is the most appropriate strategy for addressing the water quality impacts associated with future development and it is not expected that the River Road - Santa Clara Basin Plan will result in any changes to the stormwater development standards ordinance. Delaying adoption of the stormwater development standards ordinance pending completion of the River Road - Santa Clara Basin Plan is not warranted given the independence of the two efforts. Delaying ordinance adoption would also be counterproductive in that opportunities to address the water quality of runoff from sites proposed for development over the next six months would be lost, including those in the River Road - Santa Clara area. The River Road - Santa Clara Basin and the Preservation of Natural Drainage Systems Concern was expressed at the public hearing on May 8, 2006 that the more natural stormwater systems that exist in River Road and Santa Clara including roadside swales are being replaced with engineered (piped) systems for conveying stormwater upon development. Residents expressed that, given their multiple benefits, roadside ditches and open waterways should be preserved and utilized rather than replaced by piped systems. This issue will not be addressed by the stormwater development standards ordinance. As indicated above, the type of system used to convey stormwater is not dictated by the proposed ordinance, existing City Code, or
