CA selects Mobile Dredging and Pumping Co. for Lake Elkhorn Dredging
The Columbia Association (CA) has awarded a contract to Mobile Dredging and Pumping Co., of Chester, PA, for the dredging of Lake Elkhorn. The proposed dredging plan follows the permitted plan and requires no amendments to the permits obtained for this project.
The Lake Elkhorn dredging project has been in the planning and development stages for several years. CA solicited the input of residents, Board members and other stakeholders to develop a plan that responds to community, environmental and traffic concerns, and presents a responsible approach to accomplishing the dredging within budget.
After canceling the first request for proposal, re-issuance of the request for proposals for Lake Elkhorn dredging was released on July 22, 2009. Proposals were due on August 18, 2009 and CA received four proposals. A five-person, multidisciplinary evaluation team was established and the proposals were evaluated. Mobile Dredging and Pumping Co. had the highest rated proposal which was satisfactory in all terms of methodology, performance time and cost, and met all of the minimum requirements of the request for proposal.
Construction of the staging area, which is located at the parking area accessed by Broken Land Parkway and adjacent grassy area, is scheduled to begin early October 2009. Active dredging and material de-watering is scheduled to occur from November 2009 and continue into the fall of 2010. This includes the hydraulic dredging of approximately 52,000 cubic yards of accumulated sediment from the forebay pond, main lake and the tail water pond. At the staging area, the hydraulically dredged material will be de-watered and hauled by truck to off-site locations for disposal.
