City of Maryland Heights Stormwater

Location: St. Louis County, Mo.

Client: City of St. Louis, Board of Public Service

Burns & McDonnell recently assisted the City of Maryland Heights, Mo., in implementing the recommendations of a previous stormwater management study. Burns & McDonnell's assignment was to develop construction documents for correcting drainage and bank stabilization problems at 13 locations.

Additional information about three of the 13 Maryland Height’s projects:

Daley

This tributary to Midland Creek was actively incising and eroding the stream’s bank. Burns & McDonnell designed six grade control structures to inhibit additional incision. Coir rolls were placed at the toe of the eroded bank along with erosion control blankets to reinforce this bank. Plants were used at each grade control structure, coir roll and in the erosion blanket. Burns & McDonnell also prepared permanent, temporary and access easement.

Adie West of Schuetz

Fee Fee Creek was eroding the west bank and threatening a commercial parking lot and utility poles. Burns & McDonnell designed a reinforced bank slope to protect the channel banks. This reinforced slope was designed around the existing parking lot and utilities. Burns & McDonnell performed hydraulic analysis of the channel to obtain flood plain permits and MSD approval. Burns & McDonnell was also responsible for easements and 404 permit.

Wes Glen

This tributary to Fee Fee Creek was actively incising. Burns & McDonnell designed four grade control structures to prevent additional incision. Eroded banks were laid back on a 1.5 horizontal to 1.0 vertical slope and planted.

  • Field inspections and surveys
  • Geotechnical investigations
  • Alternatives analysis to evaluate a number of possible solutions
  • Presentation of selected alternative to city staff and affected property owners
  • Preparation of construction documents and right-of-way and easement plats
  • Coordination with government agencies and utility companies and acquisition of necessary permits
  • Construction services

The investigations and alternatives analyses evaluate hydraulic impacts, construction and maintenance costs, and impacts on adjacent properties. Bioengineering solutions were given preference in developing the alternatives for correcting the bank stabilization problems.
