nhc <br />2 SITE RECONNAISANCE <br />NHC visited the project site on March 29, 2018 with Jacobs and Kittitas County personnel to discuss <br />potential alternatives and gather pertinent information to support the basis of design. An additional site <br />visit was conducted on April 12, 2019 with Kittitas County personnel to assess additional survey needs <br />and meet with property owners to gain insight to their experiences with flooding along Lick Creek. <br />The existing crossing consists of two culverts, a 54 -inch diameter reinforced concrete pipe culvert and a <br />corrugated metal pipe culvert with a 36 -inch diameter inlet and a 48 -inch diameter outlet. Some woody <br />material was observed racked near the inlets of the culverts (Figure 2-1). Streambed material in the <br />vicinity of the culverts, as well as in the adjacent upstream reach, was primarily sand. <br />Figure 2-1 Inlets of Culverts at Lick Creek Crossing (Left) and View of Upstream Reach from Roadway (Right) <br />Immediately downstream of the NF Teanaway Road crossing, the channel is wider (Figure 2-2, left) than <br />the typical downstream channel section (Figure 2-2, right). This change in width is likely due to the <br />velocities exiting the existing culverts. Downstream from this location, the creek has been channelized <br />and is significantly less sinuous than the observed sinuosity upstream of the crossing. Through this <br />straightened portion of the downstream reach of Lick Creek, there are several private properties with <br />driveway culverts and structures within the floodplain of Lick Creek. <br />North Fork Teanaway Road - Lick Creek Fish Passage Enhancement Project <br />Flood Rise Analysis — Maintaining Creek Flows Along Teanaway Road <br />4 <br />
