- Drainage Improvements to Reach 1 of Sanderson Gulch along the Platte River were identified by City and County of Denver to reduce flood risk to the area.
- Improvements included the addition of a 9-foot by 7-foot cell to the existing reinforced concrete box culvert under South Lipan Street and 9-foot-high retaining walls on either side of this portion of the reach to improve the drainage Reach between the BNSF railroad bridge and South Platte River Drive.
- The culvert beneath South Platte River Drive associated with the outfall of Sanderson Gulch into the South Platte River Drive was replaced with a 70-foot span bridge along with reconstruction of approximately 400 lineal feet of roadway.
- Along with the preliminary and final geotechnical report, K+A provided geotechnical assistance during the construction phase.
