RFQ Engineering Services-Whitford Brook Watershed

Infrastructure Improvements – 2023-07

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

like fishway design plans.

Included in this design initiative (with owners indicated in italics):
