MILL POND DAM REMOVAL – Information on Project Finances & FAQ Sheet
The construction bid submitted by SumCo Eco Contracting (in April 2025) included the lowest total cost to complete the project ($3,142,193) out of the four qualified contractors that submitted bids, and was therefore selected by the Town Council to complete the project in accordance with Durham’s Purchasing Policy. Other contractors that submitted bids for the project include TFord at $3,388,500, Sargent at $3,526,550, and S&R at $4,597,240.
A question has been asked regarding the difference between the project costs presented within the Feasibility Study and the present-day cost of the project. Costs included within a feasibility study for various options were planning level costs, which was clearly articulated throughout the evaluation process. The selected option, dam removal, was further refined during final design. In addition, cost increases can be directly attributed to the following, which would have impacted any option selected:
Abnormally high inflation since 2020.
Increases in unit construction costs due to high fuel prices and increased trucking costs.
The Town was verbally notified by NOAA that the remaining $1.3 million dollars of grant funds designated for the project will not be released. Notwithstanding this regrettable news, the Town has still been successful in obtaining grant funding to support the project. Of the total estimated project costs related to construction and removal of the dam of approximately $3,692,193 (including the SumCo bid, VHB construction phase engineering services and Section 106 Mitigation Efforts), the Town has received construction funding from NOAA, NFWF, and NHDES grants totaling approximately $2,174,701, or 58.9% of total construction costs. This is in line with the estimated external grant funding % offset considered at the time of the referendum vote on the project.
The construction contract for this project was approved at the Town Council in October 2025. The contract was approved subject to either receiving the remaining funding allotment from NOAA, or the approval of a FY26 Capital Improvement Program Item in the amount of $900,000, which was included/approved by the Council as part of the approved FY 2026 budget. The current available funds are sufficient to complete the project, and not receiving the $1.3M as described above will have no impact on the scope or quality of the project, meaning the Town is not cutting out parts of the project or reducing mitigation efforts. There is not a project shortfall. Between advantageous bid numbers (described above) and the additional $900,000 allocated by the Town Council for FY 2026, sufficient funds are available for the full project and future tax impacts were integrated into the Town's current budget and future fiscal forecast as part of the FY 2026 budget approval process last fall.
THE TOWN-WIDE REFERENDUM ON THE DAM - The Town Warrant (Referendum question) from March 8, 2022, can be found below. Article 2 included the question: "Shall the Town reverse the action of the Town Council taken on November 1, 2021 to remove the Mill Pond Dam?'
Article 2 failed by a 74% vote with 1706 opposed and 596 in favor. Town officials at the time reported 2,365 people voted in the election, more than double the average turnout of a little less than 1,100 for town elections.
MILL POND DAM FAQ AVAILABLE ONLINE - (environmental implications, wildlife/habitat concerns, rationale, dredging, water quality impairments, options & preliminary engineering cost estimates, etc.) - The Town had produced an informative Frequently Asked Questions (FAQ) sheet for the community dated 1/26/22 to help answer questions concerning the Mill Pond Dam leading up to the 3/8/22 election, which is still informative today in answering recurring questions about the project. The FAQ sheet can be reviewed below.
