David J. Heinze, P.E.

Principal Environmental Engineer


Mr. Heinze has significant experience in biotechnical engineering projects from study phase through design and oversight of implementation of bioengineering solutions.  Mr. Heinze brings to Terra Technologies a strong environmental engineering background having worked for nationwide and worldwide prestigious environmental consulting firms.  Mr. Heinze has managed numerous projects of varying size (over $1M) and complexity including projects where biotechnical engineering concepts were successfully implemented.  Mr. Heinze holds a B.S. and an M.S. in civil and environmental engineering.  Selected relevant project experience includes:

  • Grand Glaize Creek Streambank Stabilization - Ballwin, Missouri - Mr. Heinze and Terra Technologies prepared a detailed Restoration Plan to restore stream conditions of a 1,500-foot section of Grand Glaize Creek that had been damaged as part of sanitary sewer construction activities for the Metropolitan St. Louis Sewer District (MSD).  The objective of the plan was to restore stream conditions to pre-construction conditions with areas of deep pools, riffles, trees and a meander to the flow of the creek.  The U.S. Army Corps of Engineers commented on the “well thought out” and “comprehensive proposal to restore the stream” to its condition before the sanitary sewer construction.  Restoration efforts were completed in the fall of 2001 and have been successful in stabilizing the stream banks and initiating the restoration of the stream’s ecosystem.
  • Stormwater Improvement Study - Crestwood, Missouri - As a subcontractor to Camp Dresser & McKee, Inc., Terra Technologies supported the Watershed Study for the City of Crestwood.  Terra Technologies inspected all of the creeks identified as part of the project to characterize channel erosion and other storm water problems. A basic geomorphic assessment of the natural channels was performed as part of the field investigation.  As part of the Storm Water Improvement Study Report, Terra Technologies provided biotechnical engineering alternatives for the high-priority problem areas identified as part of the study.
  • Southern Oaks High Bank Stabilization - Saint Charles, Missouri - Mr. Heinze was the senior project manager for the largest and most difficult high bank stabilization project ever attempted in the greater Saint Louis area.  Terra Technologies was retained as the lead designer to develop geotechnically stable bioengineered improvements for a loess high-bank slope approximately 50 feet tall along Crystal Creek.  The creek channel was moved near its predevelopment (stable) location and the high bank was stabilized with a geo-cellular confinement system.  The surface cells were planted with a mixture of native grasses, vines, and wildflowers to enhance the aesthetics.  Construction of improvements was successfully completed in Fall 2003.
