The Vermont Association of Conservation Districts (VACD) seeks proposals from engineering consultants regarding existing conditions analysis, conceptual design plans, and 30% preliminary design as part of the Preliminary Design phase of a proposed floodplain and stream restoration project with two subprojects. This project is on property bordering Potash Bay in the town of Addison, and includes culvert, tributary floodplain restoration, and shoreline restoration, and tributary wood additions. The selected consultant will be responsible for tasks including project initiation, site visit and data collection, preliminary design, refining cost estimates, and preparing a technical memorandum. • The project includes removal of culverts and roadway fill to recreate natural shoreline and floodplain confluence areas. • The project involves installation of in-stream wood structures to promote floodplain reconnection. • The project requires a topographic survey, stream bathymetric survey, and wetland delineation. • The project involves refining estimates of phosphorus reduction and opinion of probable costs. • The project requires preparation of a Preliminary Design Technical Memorandum.
