Specifications include, but are not limited to: Phase 1: 30% Design - The goal of this phase is to collect the field data, analyze the data through appropriate models and produce a 30% design for the selected option. The consultant will collaborate throughout this step with the Project Team as needed to ensure an acceptable product. Data Collection: • Perform the surveying and probing necessary to determine if removing the dam structure will likely improve passage for brook trout (i.e. presence of natural bedrock barrier), and prepare a memorandum briefly summarizing results and conclusions regarding the potential of removal to improve aquatic organism passage • Identify potential infrastructure and natural resource conflicts • Conduct topographic survey to record existing site conditions, including the channel’s natural bankfull width at the site, channel cross sections upstream and downstream of the structure, channel profile, road elevations, infrastructure that may be affected by the change, and other site features relevant to the design • Topographical survey limits shall extend a sufficient distance to define existing features related to the project site and provide sufficient information to complete a hydraulic analysis; CCNRCD will facilitate landowner communication as needed • Document the extent and approximate dimensions of the wedges of deposited sediment upstream of the weir; include an estimate of sediment volume for the weir, and outline sediment management alternatives for the weir removal; implement a sediment sampling protocol to characterize sediment quality and identify potential contaminants...
