Re: Devils Creek Capital Improvement Project (CIP)<br />
File Reference No: 2009- 026 (J) DEVIL<br />
Dear Firms/Engineer:<br />
The Stormwater Management Division of the Richland County Department of Public Works is<br />
soliciting proposals from the pre-qualified engineering firms for engineering services on Devils<br />
Creek as a measure to improve Gills Creek watershed.<br />
Project Name: Devils Creek CIP<br />
Background: This project is a result of coordinated effort among Richland County Stormwater<br />
Management, City of Columbia and Gills Creek Watershed Association in an effort to improve<br />
Gills Creek watershed. A recent field assessment was performed by both City and County<br />
representatives on the Lower Rosewood Community section of the creek located in the<br />
between Live Oak Street and South Beltline Boulevard. Stream assessment was completed on<br />
an approximate 7650 lf stretch of stream and certain deficiencies were identified. They are<br />
summarized below:<br />
The creek has been lined in the past on both sides with concrete erosion control blankets. At<br />
certain locations, there is severe undercutting on the lower portions of the ditch walls due to<br />
lack of effective blanket tuck-in. This has resulted in severe sediment deposition in the ditch.<br />
Live Oak Street and Tempo Court - Upstream, the tributary is piped but daylights at a headwall<br />
at this point. Looking downstream, undercutting has occurred, which compromises the wall’s<br />
integrity and also serves to erode beneath the blanket. The eroded soil appears to be depositing<br />
downstream.<br />
Edmond Street Bridge - Upstream of the ditch looks good. About 100 to 150 feet downstream,<br />
just beyond an existing retaining wall, the ditch walls are undercut and erosion is taking place.<br />
Kolob Street - Ditch walls upstream and downstream are undercut and erosion is evident.<br />
Nephi Street - Same failure of the blanket which results in excessive erosion.<br />

Rose Drive - Upstream and downstream ditch wall failure and ditch bottom sedimentation.<br />
Hydrangea Street- Upstream and downstream ditch wall failure and ditch bottom<br />
sedimentation.<br />
Plowden Road Bridge - Just upstream of the bridge is the worst area for sediment deposition.<br />
The tributary widens just above the Plowden Road Bridge; the water slows down and sediment<br />
drops out. Downstream of the bridge, sediment is also excessive.<br />
Railroad Access Road – The tributary is directed beneath the railroad tracks and associated<br />
access road by two seventy-two inch (72”) pipes. Upstream the tributary appears to be in a<br />
natural state with no obvious sediment or erosion issues. There is less canopy cover on the<br />
downstream side, but no excessive erosion was noted.<br />
South Beltline Blvd. Curve - The tributary is directed beneath South Beltline via large culverts<br />
placed at a sharp angle. The water backs up, erodes the bank, and deposits sediment in the<br />
ditch on both sides of South Beltline. The angle of the culverts also creates a log jam effect<br />
with debris backing up on the upstream side of the culvert.<br />
Wetland Mitigation - A parcel of R13611-02-17 (shown in attachment C) was identified as a<br />
probable site for wetland mitigation/conservation.<br />
Scope of the project: The general scope is to provide engineering services to perform<br />
maintenance and repairs to the ditch identified in Attachment A (map attached). Scope includes<br />
removal of over grown vegetation, removal of accumulated sediment, performing repairs to the<br />
creek and application of appropriate bank & bed “localized” stabilization to the mentioned<br />
section of ditch to prevent future erosion/scouring. It is to be noted that this project is not a full<br />
length stream stabilization project.<br />
Also, the project includes performing a feasibility study to involve parcel R13611-02-17,<br />
shown in Attachment C to mitigate wetlands/conserve property and buffer the airport.<br />
Scope of services: The services to be provided under this project will include:<br />
Surveying - The engineer will provide all design surveying and initial construction staking.<br />
As-built surveying will be performed upon completion and delivered in accordance with<br />
Richland County’s Digital Data Submission Requirements.<br />
Permits - The engineer will prepare and submit all applicable permit applications and followup<br />
through approval prior to advertisement of the project for construction bidding.<br />
Geotechnical Investigation - The engineer will provide all subsurface exploration and soil<br />
testing required, if any, to accomplish the design phase.<br />
Design Calculations - The engineer will perform all engineering calculations necessary to<br />
complete the plans and contract documents for the project. Neighborhood meetings may be<br />

necessary to address concerns overlooked by calculations. Engineer provides materials for<br />
neighborhood meetings as needed.<br />
Monthly Project Update Meetings – The engineer will meet with Richland County Project<br />
Manager once a month till the close out of the project to update and discuss path forward for<br />
the project. Engineer will prepare minutes for these meetings and provide to Project Manager<br />
within 3 days of the meeting.<br />
Utilities - The engineer will perform all necessary surveying and research required to<br />
determine all utilities that affect the design and construction of the project. The engineer will<br />
be responsible for de-conflicting utilities and coordinating with contractor for utility relocation.<br />
Exposed sanitary sewer lines should be addressed, as they present water quality risks.<br />
Construction Plans and Specifications - The engineer will prepare detailed plans and technical<br />
specifications for construction of the project with enough copies to complete the bidding<br />
process. The engineer will provide Richland County with three copies of the plans and<br />
specifications prior to bid. In addition, the engineer will provide the selected contractor with<br />
three copies of the plans and specifications.<br />
Drainage Easements – The engineer will determine the necessary easements/one time<br />
permissions required for construction of the project, as well as slope permissions, temporary<br />
construction easements, etc and prepare necessary language for acquiring them.<br />
Acquisitions - Richland County obtains easements/permissions as per directions from the<br />
engineer. At present, the properties affected by the project have not been determined.<br />
Cost Estimate - The engineer will provide an engineer’s cost estimate of construction costs for<br />
the project.<br />
Bid Documents - The engineer will prepare all necessary bid documents required for bidding<br />
the project. All bid documents will be reviewed by the Stormwater Management Division and<br />
the Richland County Procurement Department prior to advertisement of the project for bids.<br />
