Council approves $144,660 design contract for 17th Street drainage improvements
Summary
Council authorized design and permitting work to replace an open ditch east of Q Avenue with a piped storm system and to extend the outfall into Fidalgo Bay; the design contract was awarded to Osborne Construction Inc. for $144,660.
The Anacortes City Council approved a contract June 9 to design and permit the Seventeenth Street drainage improvement project, a city-led effort to replace a chronically clogged open ditch with a piped storm system and extend the outfall farther into Fidalgo Bay.
City staff said the open ditch east of Q Avenue carries stormwater from a large upstream basin that repeatedly fills with sediment and reed canary grass; vegetation and sediment restrict flow and cause surcharge at Q Avenue during heavy rains. Staff recommended installing a buried storm pipe, relocating and extending the outfall to avoid future conflicts with the planned shoreline trail and to preserve system access once nearby development (MJB) restricts maintenance access across Port and School District easements.
Kermit Esterholt (project presenter) said the design phase will produce bid-ready documents and permitting. The council approved a contract for design and permitting with Osborne Construction Inc. in the amount of $144,660. Councilmembers discussed outfall location, pipe sizing and routine maintenance; staff said the existing downstream pipe appears adequate and the work will focus on replacing the open ditch segment and extending the outfall.
Council and staff also noted water-quality considerations; staff said the scope will examine whether a treatment system is feasible at the outfall and will report findings during design. The contract covers design and permitting only; construction would require a later authorization.
