RFQ Engineering Services-Whitford Brook Watershed Infrastructure Improvements – 2023-07 Town of Ledyard, CT RFQ 2023-07-Whitford Brook Watershed Infrastructure Improvements 1 Public Works Department Town of Ledyard, Connecticut Request for Qualifications Engineering Services In Connection with Whitford Brook Watershed Infrastructure Improvements The Town of Ledyard is accepting qualification statements from professional engineering firms or teams licensed in the State of Connecticut to provide engineering services in connection with improvements to several infrastructure components in the Whitford Brook (Lantern Hill Valley) watershed. These services are part of the approved scope of a State of Connecticut Personal Services Agreement (PSA). The firm(s) should be able to demonstrate a successful track record in working on municipal infrastructure projects in Connecticut, particularly bridges, culverts, and dams, and knowledge and expertise in related engineering and design, watershed

hydrology, hydraulic analysis, fishway improvements, and in relevant regulatory requirements. Interested firms should submit statements of qualifications (5 copies) to the Mayor’s Office, 741 Colonel Ledyard Highway, Ledyard, CT 06339 no later than 2:00 PM on Tuesday, March 21, 2023. They should be marked “Engineering Services – Whitford Brook Watershed Infrastructure Improvements – RFQ 2023-07.” Project Background The Town of Ledyard has received approval from the State of Connecticut Personal Service Agreement (PSA) funding toward the replacement of Lantern Hill Road Bridge (CT No. 137001) and engineering design for several other infrastructure components in the Whitford Brook/Lantern Hill Valley watershed. The Town of Ledyard is assigned as the lead in project administration and will consult administrative representatives of the Towns of Stonington and North Stonington, the Mashantucket Pequot Tribal Nation (MPTN), the Lantern Hill Valley Association, aka LHVA, the McKee Farm Trust, aka MFT, the owner of the Hyde Mill Pentway, Save the Sound, CT DEEP, other state agencies as necessary, and federal partners needed to complete the work of the Project. The Town is seeking a comprehensive approach to engineering design that contemplates all infrastructure components in the hydrologic context of the Whitford Brook watershed from the existing Lantern Hill Pond dam down to the parallel crossings at Wolf Neck Road (Bridge Nos. 137002 and 137003). Consult the attached graphics for component locations within the topographic context. A key element of this project is repair design for the three dam structures (listed below) on Long Pond and Bush Pond. Save the Sound and Princeton Hydro (in cooperation with dam owners, abutters, and CT DEEP) have developed advanced design plans for the Long Pond Dam nature-like fishway that will be incorporated into the dam repairs specified in this RFQ. Save the Sound and Princeton Hydro will RFQ Engineering Services-Whitford Brook Watershed Infrastructure Improvements – 2023-07 Town of Ledyard, CT RFQ 2023-07-Whitford Brook Watershed Infrastructure Improvements 2 be available during this project for necessary coordination. Consult attached nature- like fishway design plans. Included in this design initiative (with owners indicated in italics):   Repairs at Long Pond Dam (Dam 7202) – LHVA (In coordination with Princeton Hydro and Save the Sound, incorporate the nature-like fishway as described in advanced design plans [see  below])   Repairs at Bush Pond Dam (Dam 10248) – LHVA   Repairs at Bush Pond Dike (Dam 10249) – MFT   Replacement of Whitford Brook Bridge/Culvert – Ledyard (approximately 420 feet south of the Long Pond Dam located on Lantern Hill Road)   Replacement of Hyde Mill Pentway Culvert – MFT Not included in the scope of the PSA, but to be integrated hydrologically as relevant in this project:   Lantern Hill Pond Dam (new in 2010 through MPTN initiative) – MPTN   Box Culvert (approximately 300 feet south of Homestead Rd, new in 2010 through MPTN initiative) – Ledyard/North Stonington   Lantern Hill Rd Bridge over Long Pond/Bush Pond connector (CT No. 101008) – North Stonington   Long Pond Nature-like Fishway – LHVA (a separate initiative of Princeton Hydro and Save the Sound for which design plans are at an advanced stage of development)   Lantern Hill Road Bridge (No. 137001) over Whitford Brook (plans complete, permitting in process) – Ledyard/Stonington  11 Whitford Pond Dam (Dam 7203) – privately owned, traversing Ledyard/ Stonington line  12 Wolf Neck Road Bridge (No. 137002) over Whitford Brook – Stonington  13 Wolf Neck Road Bridge (No. 137003) over Whitford Brook – Stonington RFQ Engineering Services-Whitford Brook Watershed Infrastructure Improvements – 2023-07 Town of Ledyard, CT RFQ 2023-07-Whitford Brook Watershed Infrastructure Improvements 3 Potential Engineering Services* * Specific services will be subject to negotiation, the following are exemplary and services may be added or deleted from the ultimate agreement. 1.
