Water Resources Projects
Streambank Stabilization: Evaluated streambanks for erosion that compromised the capacity of the downstream water supply (Lake Perry Reservoir) and eroded farm fields. Over 40 sites have been assessed, surveyed, designed, permitted and successfully constructed. Over 15 miles of streambank and over 150 acres of riparian habitat have been restored.
Digital Flood Insurance Rate Map and Flood Insurance Study: Gredell Engineering staff successfully completed a Digital Flood Insurance Rate Map (DFIRM) and Flood Insurance Study (FIS) report for Butler County, Kansas, the largest county in Kansas. Hydrologic analyses were completed for approximately 1,065 square miles of flooding sources with greater than one square mile of drainage area. Peak flood discharges were calculated for the one-percent annual chance storm events for all streams with drainage area greater than one square mile. Hydraulic analyses were performed with modeling that includes the one-percent annual chance storm events, based on peak discharges computed in the hydrologic analyses. Cross section and field data were used to perform the hydraulic analyses.
Lake Shoreline Stabilization: Gredell Engineering staff successfully prepared engineering design, plans, and specifications for the stabilization of an approximately 900-foot section of shoreline on the edge of Thomas Hill Reservoir that was being undercut by wave action. The design also included a jetty to protect a marina cove. Prepared base mapping for the project, identified the geometry of the slope failure zone and subsurface conditions critical to design and construction, and prepared construction documents for bidding purposes in order to complete the stabilization work with limited construction oversight.
Road Failure from Streambank Erosion: Gredell Engineering staff successfully prepared engineering design, plans, and specifications for the streambank stabilization of the Lincoln Street slope failure in Jefferson City, Missouri. Secured a U.S. Army Corps of Engineers (USACE) Nationwide 404 Permit (NWP) and prepared construction documents for bidding purposes in order to complete the stabilization work with limited construction oversight. Performed a site reconnaissance, located utilities, arranged for the preparation of a project base map, performed a stream assessment, and conducted a subsurface investigation consisting of three geotechnical borings at the site of the roadway embankment failure. Services also included evaluating streambank stabilization alternatives; evaluating the geometry and soil parameters of the slope failure surface; assessing the location of groundwater and evaluating its potential impact on geotechnical related design and construction; and evaluating the suitability of on-site materials for use as controlled fill.
