Lakewood Creek West Drainage Investigation
Village of Montgomery, Illinois
EEI conducted a drainage investigation and hydrologic and hydraulic modeling for an existing subdivision experiencing flooding problems. The design for the subdivision had underestimated the amount of off-site tributary area coming to the development and as a result, the detention basins were filling and staying full causing ponding water and basement flooding in the area.
Highlights
2018-2019
- Drainage Investigation
- Hydrologic and hydraulic modeling for existing subdivisions experiencing local flooding
- Creations of an EPASWMM model of the tributary watershed, the developments, and the series of detention basins and their interconnecting restrictor structures and storm sewers
- Alternatives included increased restrictor sizing, additional outfall storm sewers, bypass storm sewers, and increased storm sewer sizing between detention basins
- Cost estimates for alternatives and phasing plans
- Designed new bypass storm sewer for off-site flows
