Melvin Wharf Road Stormwater Management and Control Designs

April 4, 2025

Introduction and Background

This project builds on more than ten years of effort by the Lake Winnipesaukee Alliance to improve, protect and restore the water resources within Lake Winnipesaukee's watershed. Nutrient loading to Lake Winnipesaukee is over 300% natural background levels, which has led to the lake being listed on the NHDES 303(d) list as impaired for aquatic life use. A direct relationship exists between increased levels of nutrients in the lake and aquatic plant and algal growth, and cyanobacteria abundance. Only through continued implementation of watershed management practices to reduce sediment and nutrient loading to the lake, will we succeed in the long-term protection of Winnipesaukee.

Sources of pollution in the watershed impacting the lake’s water quality include stormwater runoff from developed areas, shoreline erosion, gravel roads, improperly functioning septic systems, and more. The 2020 Moultonborough Bay and Winter Harbor Watershed Management Plan identified 107 sites contributing excess nutrient loading to Lake Winnipesaukee. This project will implement stormwater control measures at one of the sites identified in the plan, resulting in a reduction of sediment and nutrient loading to Moultonborough Bay, Lake Winnipesaukee.

SCOPE OF SERVICES

The anticipated scope of work will include development of designs and final bid package for stormwater control measures on Melvin Wharf Road, Tuftonboro. Conceptual designs are reviewed with the Town of Tuftonboro and LWA before final designs and bid packages are developed. Final bid documents will include plans, specifications, and construction cost estimates needed in order for the Town to bid the projects.

Description:

Site MoB 1-06A: Melvin Wharf Road, Tuftonboro, NH

There is beach erosion from Melvin Wharf Road drainage, that flows over the beach and erodes the sand into the lake.

The intent is to install a trench drain to collect runoff from the road terminus and roadside ditch with conveyance to a new best management practice, i.e. bioretention area. The bioretention area will have a raised outlet to retain and infiltrate stormwater while providing overflow to pipe for erosion resistant conveyance of larger storms.

The project also involves replacing an existing old buried culvert for conveyance of larger storms not infiltrated in the bioretention area.

Mitigation of this site is estimated to reduce sediment and nutrient loading to Melvin Bay by 154 lbs./yr. of total suspended solids and 0.3 lbs./yr. of total phosphorus.

Tasks

Task 1: A licensed land surveyor will perform a topographic survey and furnish a base plan of existing conditions for Melvin Wharf Road, Tuftonboro.

Task 2: The engineering firm will analyze the overall drainage system along Melvin Wharf Road and provide a report to LWA.

Task 3: The engineering firm will prepare documentation required for Shoreland Permitting and Wetlands Permitting with NHDES as part of any set of bid documents.

Task 4: The engineering firm will draft conceptual designs for stormwater control measures on Melvin Wharf Road incorporating information gathered from the survey, site walk, and abutter information.

Conceptual designs are reviewed by LWA and the Town of Tuftonboro.

Task 5: The engineering firm will develop final designs based on input and feedback from the LWA and Town of Tuftonboro. Final designs will include a basic set of bid documents (plans, specifications, and construction cost estimates). Final design bid packages are submitted to NHDES for approval.
