Gibbs & Olson has hired T.J. Griggs as a project engineer. Griggs graduated from Washington State University’s civil engineering program and holds an engineer-in-training certification. He is currently working on road, site, sanitary sewer, and water design project elements, as well as the analysis and design of stormwater detention and treatment systems.
Gibbs & Olson is excited to welcome Samuel Barham, PE to our team as a project engineer. Mr. Barham has over thirteen years of civil engineering experience with a strong knowledge of water, wastewater and transportation infrastructure for the public sector. His experience includes working on projects for the cities of Longview and Spokane as well as the Washington State Department of Transportation. He earned his bachelor of science degree at the Oregon Institute of Technology and is a licensed engineer in the state of Washington.
The City of Longview is replacing an aging 8 foot by 5 foot box culvert located in the center of a 60-foot wide median. Gibbs & Olson was recently hired to provide the planning, permitting, land surveying, design and construction phase services to replace the box culvert system. The project is approximately 2,600 linear feet and the total drainage basin collected by the existing box culvert is approximately 220 acres. Stormwater enters the box culvert from the contributing drainage area at numerous locations. The stormwater is collected at each intersection along Beech Street and is also collected in small branches consisting of 1 to 3 inlets that are directly connected through the side wall of the culvert with 8 inch concrete pipe. In addition, there are six larger collection system at various locations.
The current box culvert discharges to an existing 42 inch aluminum stormwater trunk line and outfalls into CDID Ditch 1. There is an overflow from one of box culvert which outfalls to CDID Ditch 3. Discharge to this overflow occurs when the water level in the box culvert is greater than one foot in depth.
Station 25 Lexington
Station 22 Bakers Corner
Stations 22 and 25 move into the permitting phase. Working closely with Cowlitz 2 and Rice Fergus Miller Architects, Gibbs & Olson is providing survey, design, permit assistance, bid and construction phase engineering for the two stations.
