NPDES Oak Ridge Park East Stream Restoration

Solicitation 27-009 is a request for sealed bids from the Charles County Government for the NPDES Oak Ridge Park East Stream Restoration project in Hughesville, Maryland. The project is designed to meet Maryland Department of the Environment and National Pollution Discharge Elimination System permit requirements by obtaining impervious area and nutrient reduction credits. The scope of work includes installing a stormwater detention facility, restoring approximately 1,400 linear feet of an eroding unnamed tributary to Gilbert Run using in-stream and bank stabilization structures, and stabilizing 120 linear feet of an eroding outfall channel. The contract will be awarded to the lowest responsive and responsible bidder who has been a legal entity in the field for at least five years. The project requires strict adherence to technical specifications, including a mandatory Critical Path Method schedule and compliance with Maryland State Highway Administration and Charles County construction standards. Key contractual obligations include a five percent bid bond, the use of Maryland prevailing wage rates, and the provision of performance and labor bonds. Upon completion, the contractor must provide a one-year warranty and ensure an 85 percent survivability rate for planted trees and shrubs over three years. Final payment is subject to a five percent retainage, which may be replaced by a maintenance bond, and is contingent upon the submission of as-built drawings and geotechnical inspection reports. Bids must be submitted electronically by October 13, 2026.
