Clinton Street area CSO abatement

Quick reference
— Phase II Conveyance-related work (June 2008)
— RTF bids rejected
— Public meeting and hearing

Onondaga County is working to abate combined sewer overflows (CSOs).

CSOs create human health risks because they add bacteria, floating trash, organic material, heavy solids, and grit to city streams and Onondaga Lake. Material from CSOs collects on vegetation along and in streams. It looks bad and smells bad, and it can also transmit disease to humans who may come in contract with the water. Material from CSOs also depletes the dissolved oxygen in the water that is necessary for aquatic life.

By implementing this project, Onondaga County will meet or exceed federal and state water quality requirements, reduce human health risks associated with the discharge of untreated sewage to Onondaga Creek and Onondaga Lake, and eliminate odors caused by discharging overflows. The County will also make improvements to the area affected by construction of the abatement work. The following documents describe this project in detail:

Public hearing transcript — Responses

The goal of the Clinton project is to abate eleven CSOs between Fayette and Oneida streets near downtown Syracuse.

Transportation engineers will develop ways to maintain, as much as possible, the flow of traffic and the supply of parking spaces both during and after construction of the facilities. The Environmental Information Document examines this and other potential environmental effects of the project.

Construction continues to progress

Phase II Conveyance-related work (June 2008)

Mobilization continues on project the site. Exploratory borings were completed to help develop the dewatering plan.

Contract 2A covers pipe installation under the railroad near RTF to the rear of the MOST and will take in one CSO (030).

Upcoming work:

Finish exploratory borings
Install two dewatering test wells
Begin installation of geotechnical monitoring instruments
Install construction fencing, and place signage for road detours.

RTF bids rejected

The County notified bidders on April 25, 2008 that all bids on the Clinton RTF project were rejected. Working with the ACJ parties and others, the County will pursue implementation of alternatives technologies to address the Clinton CSOs. These technologies will include green infrastructure projects.
