P a g e | 3 Fish Passage Barrier Inventory and Assessments Program Assumptions  The City will inform Osborn with their preferred method of data collection for barrier assessments, being either paper or digital forms of submittal.  The City will obtain Right of Entry permission from landowners for crossings that occur on private land.  High and low fish passage flows will be calculated using regional regression equations.  The barrier assessment will include up to the 78 complex culvert sites the City has previously identified. Further evaluation of these sites, based on their complexity, may be authorized by the City under Task 4.  There may be stream crossings which are unable to be accessed and/or have their barrier status properly assessed according to WDFW’s protocols due to landowner permission or geographical access.  Two Osborn staff will perform up to 8 days of field reconnaissance.  The City will allow Osborn to lift manhole lids in stormwater systems to perform measuredowns for slope or water surface drop measurements.  If stormwater infrastructure that needs to be assessed as part of the barrier assessment is located within travel lanes, Osborn will coordinate traffic control needs with the City to facilitate performance of this work. If possible, assessment of these sites will be included in the list of data needs provided to the City prior to field work.  Osborn will perform light brush removal, if needed, to access sites (e.g. brush that can be cleared with loppers). If more substantial clearing is required, Osborn understands assistance may be available from City crews. If possible, sites requiring clearing assistance will be included in the list of data needs provided to the City prior to field work.  The City will provide consolidated review comments on the Draft Assessment Protocols Memorandum.  The following “eligible expenses” are identified for this task: mileage and field equipment (to perform clearing and measurements).  The City plans to form their fish passage barrier statuses according to WDFW’s Fish Passage Inventory, Assessment, and Prioritization protocols. Barrier statuses will be categorized accordingly as; 100%, 66%, 33%, and 0% passable according to WDFW’s metrics when sites are possible to properly assess. Deliverables  Provide a list of data needs to the city prior to initiating field work. City staff may be able to gather measure-downs and other data as need.  Excel spreadsheets and field data forms with updated fish passage barrier statuses for desired crossings according to WDFW fish barrier assessment protocols.  Draft and Final Assessment Protocols Memorandum, including daily field logs, in MS Word and PDF format.  Field documentation forms needed for the City to provide WDFW for the Statewide Fish Passage Inventory Task 4 Task 4 Unauthorized Additional Services
