Shipyard Road Bioengineering
Practice Final Design
Friends of Northern Lake Champlain
Request for Proposals
May 2023
A. Introduction
Friends of Northern Lake Champlain (FNLC) received a grant in 2021 from the Lake Champlain Basin Program to conduct a shoreline assessment of the towns of Swanton and Highgate. This assessment resulted in two 30% engineering designs for stormwater management practices, one in each town. The proposed Highgate project was designed for the boatlauch and picnic area along Shipyard Rd in Highgate Springs (Figure 1). According to the preliminary design final report, the public visibility of this location, its direct connection to the shore, known drainage issues, and a failing sea wall all contributed to this site being selected for concept design.
The site features a concrete seawall along the lakeshore, which is cracking and deteriorated. Additionally, runoff flowing down Shipyard Road from the west currently sheet flows and pools on the southern side of the road and then flows over the road surface towards the beach in larger storm events (Figure 2). This flow does not have a viable path to the small stream to the east.
The concept design proposes to replace the failing sea wall with encapsulated soil lifts. Two small rain gardens near the entrance to the boat ramp are proposed to treat stormwater runoff from the parking area as well. In addition to the structural practices, a swale and culvert on the southern side of Shipyard Road across from the beach are proposed to properly manage this runoff and direct it to the stream rather than over the road. The encapsulated soil lifts proposed in this design are a bioengineered practice which would convert the existing “grey” stabilization practice to a living shoreline.
FNLC has received a grant from the Missisquoi Basin Water Quality Council (BWQC 6) to develop a final engineering design for this project, which can be used for implementation. We hope to subcontract with an environmental consultant to develop the final design. FNLC will provide project management and outreach to municipal partners, landowners, and other stakeholders, as well as present findings to the Town of Highgate Selectboard.
B. Scope of Work and Timeline
B. Content of Proposals
Responses to this request for proposals (RFP) should consist of the following:
-
A statement identifying individuals who participated in the preparation of the proposal as well as a single point of contact.
-
A list of individuals that will be committed to this project and their professional qualifications. The names and qualifications of any sub-consultants shall be included in this list.
-
A scope of work and project budget. The budget should provide hourly rate information. The effort will be reimbursed on a time and materials basis.
C. Project Budget
Friends of Northern Lake Champlain received a grant from the Missisquoi Basin Water Quality Council with a budget of $12,000 allocated to consultant fees to develop the 60% design, 100% final design, documentation of required permits, O&M agreement, final design report, opinion of probable cost for implementation, and basic bid document for implementation.
D. Other Requirements
FNLC requires its contractors to maintain workers compensation and liability insurance. Contractors must submit proof of adequate insurance coverage on an annual basis for the duration of the project. The Contractor shall, at its sole expense, obtain and maintain in force, and shall require any subcontractor or assignee to obtain and maintain in force, both for the benefit of FNLC, the following kinds and amounts of insurance:
-
Workers’ Compensation Insurance. The policy shall cover the obligations of the Contractor in accordance with the Workers’ Compensations Law and Disability Benefits Law covering all operations under the Contract, whether performed by it, or by its subcontractor.
-
Liability and Property Damage Insurance. Unless otherwise specified, each policy shall have limits not less than: $2,000,000 combined (Bodily Injury & Property Damage); $3,000,000 aggregate, single limit per occurrence.
