Soil Development and Revegetation on Sloped Gulf Coast Sediments

Presenters: Carolyn White, MLA CPESC CERP & John Moss

This presentation provides details regarding stockpile trials used in the design and establishment of the Memorial Park Land Bridge & Prairie Project in Houston, Texas. This project includes construction of a land bridge feature over Memorial Drive, a major thoroughfare that bisects the Park. Excavation and native grassland revegetation of an adjacent basin area provides fill material to construct the land mass over tunneled roadway segment. Other stockpiled materials, available from an on-site lake construction project will be used as fill. The stockpiled sediments from the Eastern Glades lake provided an ideal opportunity for MPC and the project design team to trial slope stabilization, soil development, and revegetation methods on the subsurface sediments typical of the area.

Learning Objectives: 
  • Understand and evaluate methods for soil development in Gulf Coast plain subsurface sediments.
  • Understand and evaluate methods for slope stabilization in Gulf Coast plain subsurface sediments.
  • Understand and evaluate methods for revegetation of Gulf Coast plain subsurface sediments.
