Halfmoon Lake Watershed-Based Management Plan Implementation – Phase 1

The Halfmoon Lake Association (HMLA), in cooperation with the New Hampshire Department of Environmental Services (NHDES), is issuing a Request for Qualifications (RFQ) for stormwater control design and implementation services to support watershed-based management planning for Halfmoon Lake in Alton and Barnstead, New Hampshire. The procurement seeks qualified contractors to develop comprehensive stormwater management solutions targeting three priority sites with estimated combined phosphorus loads of 2.7 kg per year, including the Boat Ramp and Road Shoulder in Barnstead, the Public Boat Launch on Route 28 in Alton, and the Dalton Drive Beach Ramp in Barnstead. Deliverables include Site Specific Project Plans, conceptual Best Management Practice (BMP) designs with cost estimates, permit applications and supporting documentation, Operation and Maintenance plans, BMP construction supervision, pollutant reduction calculations, Non-Point Source pollution reports, and conceptual designs for additional BMP sites as directed by HMLA. The primary objective is to reduce phosphorus discharge and stormwater runoff into the 288-acre Halfmoon Lake through implementation of evidence-based stormwater control measures. Required qualifications include demonstrated experience with similar watershed improvement projects, expertise in developing SSPPs and O&M plans, proficiency in BMP load reduction modeling and Pollutant Control Reports, knowledge of stormwater BMP design and implementation, familiarity with the Halfmoon Lake Watershed, and comprehensive understanding of local, state, and federal permitting requirements in New Hampshire. Evaluation criteria emphasize project team experience, technical expertise, and demonstrated capability in watershed management. The deadline for submitting qualification packages is March 20, 2026, at 5:00 PM, with questions due by February 27, 2026; HMLA reserves the right to conduct interviews with qualified applicants and will negotiate scope, schedule, and fees with the highest-ranked firm.

The RFQ indicates that selected contractors must be eligible to receive federal funding and must certify compliance with applicable State and Federal grant rules, as the project is funded through a Clean Water Act Section 319 Grant awarded to HMLA in September 2024 by NHDES and the U.S. Environmental Protection Agency (EPA). No specific set-aside designations for disadvantaged enterprises or women/minority-owned businesses are identified in the available documentation. No incumbent vendors or current contractors are listed for this Phase 1 implementation effort. The RFQ does not specify a defined budget range or maximum award value in the available materials; however, the scope encompasses multiple technical services including design, permitting, construction administration, and reporting across multiple sites, suggesting a substantial contract value. HMLA explicitly reserves the right to reject any or all submittals and to eliminate tasks from the contract scope based on the outcomes of related activities or changes in grant funding availability, providing flexibility in the final award structure and contract terms.
