Covington Woods Drainage

Covington Woods Drainage

The City of Sugar Land retained Dannenbaum to evaluate the entire drainage system of Covington Woods Subdivision and to make specific recommendations regarding frequent street ponding and sheet flow conditions. This project involves a combination of channel improvements, storm sewer and inlets that are proposed to address street flooding. Due to the construction costs, a phasing plan was recommended.

West Marys Creek

West Marys Creek

Dannenbaum investigated the feasibility of a regional detention site on Mary's Creek in the City Pearland. This project was a regional detention pond with approximately 765-acre-feet of storage. Additional work included a 20,000 GPM pump station, channel improvements, and design of a reconfigurable weir.
