COYOTE CREEK ENVIRONMENTAL SERVICES Natural resource Im~entory, Assessment, Ecological Design and Permit Facilitation June 4, 2003 Mike Shields City of Eugene Public Works /Engineering 244 East Broadway Eugene, Or. 97401 Re: Revised Estimate to Conduct Rare Plant Surveys, Wetland Delineations, JPA Preparation for the 2 Owosso Culvert Projects Dear Mike, Thank you for the conversation late last week with Gale Mills regarding the scope of services for the above projects. Again, it had been my intent to submit what I anticipate represented a "worst-case scenario" in order to minimize future paperwork. However, I certainly understand the need to authorize only the work necessary and it is my pleasure to submit this revised proposal to you. The following is my recommendation for the tasks, and my best estimate of the time and costs, necessary to determine the extent of jurisdictional and protected species issues. The Tasks are described below together, but the estimates are presented separately for each culvert project. Project Understanding The City of Eugene is moving forward with plans to install culverts at two locations near the Owosso Bike Bridge: one culvert will be installed beneath the bike path at a low topographic point just south of the wastewater treatment plant, and the second culvert will be installed (as an extension of an existing culvert) on the north side of River Avenue. The culvert on the bike path is necessitated bylong-documented complaints of Sooding experienced at nearby residences. The topography at this location appears to represent a low, remnant meander scar, with slight gradient. The culvert at River Avenue is necessitated as part of the River Avenue Improvement Project, which will include widening to accommodate a center turning lane / refuge, bikepaths and sidewalks. The issues that you have requested assistance in resolving include identifying where and if protected or rare plants are likely to be present; and identifying whether wetlands are or are not present at the sites (wetland determinations). The Study Area for the Owosso Bikepath Culvert will extend approximately 15'~ up and down the Bikepath from the culvert installation area, and approximately 30' from the tce of slope of the Bikepath embankment. The Study Area for the 27661 Crow Road River Avenue Culvert Extension will consist of a corridor approximately 60' Eugene, OR 97402 wide, extending approximately 90' north from the edge of pavement of River Tel.

Office Research ~yoteCreekE~a7,peoplepc.com I will compile and analyze the existing information for the areas, including the site history, soil survey, air photo libraries (yours should prove particularly valuable), and the previous wetland delineations in the vicinity.
