SECTION 1 Introduction vertical separation to seasonal high groundwater and thus pose the highest relative risk to groundwater quality. As with all capital projects when they are selected for implementation, the planning -level concepts were viewed from a more detailed perspective taking into account neighborhood input, stormwater characteristics (e.g. soil types, slopes, catchment area), system design opportunities and constraints, and cost effectiveness. Final design for both projects includes constructing a piped conveyance system which will collect the stormwater runoff from these two areas and, in each case, direct it to a neighborhood vegetated infiltration facility. In the case of the Shirley project, the infiltration facility will be located in Ferndale Park and has been designed to meet multiple objectives including consistency with park planning objectives. Designs for these two initial projects have been finalized and construction is scheduled for summer /fall 2012.

Street Design Standards Low impact development ( "green streets "), the Pedestrian & Bicycle Master Plan "tool box" the update of the Transportation System Plan and the Envision Eugene strategies are driving the need to review and update the City's street standards. The green street concepts developed as part of the River Road — Santa Clara Basin Plan (Figures 4 -5 through 4 -10) will be utilized inasmuch as they illustrate potential configurations for incorporating vegetated stormwater facilities that infiltrate runoff from the adjacent right of way. The Basin Plan concepts are simply meant to help inform the street design standards update, and do not, in and of themselves, translate directly to new standards. Updating the street design standards is included in the Engineering Division's FY13 work plan.
