Manastash Road Creek Bank Stabilization Project

All bid proposals shall be accompanied by a bid proposal deposit in cash, certified check, cashiers check, or surety bond in an amount equal to five percent (5%) of the amount of such bid proposal. Should the successful bidder fail to enter into such contract and furnish satisfactory performance and payment bonds within the time stated in the specifications, the bid proposal deposit shall be forfeited to the Kittitas County Public Works. This project has a DBE Goal of 11%. Project End Date: September 30, 2024 Kittitas County (County) needs to repair an actively eroding bank on Manastash Creek that has caused ongoing loss of the traveled surface of Manastash Road. The original roadway embankment was composed of a rock revetment that has been impacted by stream erosion. The bank repair project is located on Manastash Road, west of Interstate 90 (I-90) and the town of Ellensburg. The project will reconstruct the eroded creek bank, prevent further erosion and roadway loss, and increase aquatic habitat complexity by the placement of rock, large woody debris (LWD), and revegetation. The project design replaces the previous rock embankment with a design that incorporates flow deflection structures combined with a woodstudded rock revetment to reconstruct the road embankment, provide long-term protection of the roadway, increase channel complexity and floodplain connectivity, and arrest further up- and downstream erosion. The revetment and suitable bank area will be planted with native riparian vegetation to replace lost riparian function and long-term roadway protection.
