Restoration Alternatives Development and Evaluation
West Branch Grand Calumet River
January 2002
Results of Phase I
• December 11, 2001 Site Visit
• Reviewed Literature and available data

Proposed Project Reaches and
Past Sample Points
Burton & Dorkin, 1994
Data Gap 1Bathymetric / Topographic Survey
• Establish Riverbed Topography & Core Sample Elevations
• Develop Remedial Alteratives & Establish Dredging / Capping Quantities
• Assess Potential Disposal Sites
• Evaluate Potential Access to River
• Aid in Preparation of Final Restoration Plans
Data Gap 2Need Engineering Base Drawings
• Historical Sampling Locations
• Proposed Sampling Locations
• Show Contaminated Sediment Sections
• Lay Out Preliminary Dredge / Capping Prisms & Materials
• Preliminary Locate & Lay Out Access Sites & Potential Disposal Areas
Data Gap 3 Transfer Sediment Core Data to Base Drawings
• Calculate (X,Y,Z) Sediment Core Data Locations Based on Bathymetric
Survey
• Place Data on Base Maps
Data Gap 4 Proposed Additional Core Boring,
Sediment Chemical / Physical Properties
• Between Indianapolis Blvd & White Oak
• Between White Oak & Columbia Ave.
• Between Columbia Ave. & Calumet Ave.
• Between Calumet Ave & Sohl Road
• Between Sohl Road & Hohman Ave.
• Between Railroad Bridge & State Line
Proposed Sampling
Data Gap 5Need Information on Access Sites
• Very Shallow Water
• Limited Access and Bank Stability for Equipment Insertion, Dewatering, Hauling
• Bridges have no Horizontal or Vertical Clearance for Equipment Movement from River Reach to River Reach
Data Gap 6Local Sources of Services & Material
• Information is needed on:– Local Labor– Dredging Equipment– Construction Equipment– Fleet Vehicles– Aggregate & Sand– Concrete– Related Services
What’s Next
• Do we Proceed with Phase 2?
• Do we do all proposed sampling or reduce number?
• Are all parameters identified?
• Should we do additional Toxicity Sampling?
• Do we obtain New Aerial Photos to develop topographic base maps or can we use some flown in 1994 or 1995?
