Bathymetric Survey of the Quinnipiac River in Meriden and Southington2

Project Spotlight – Franklin Surveys has recently completed comprehensive topographic and bathymetric survey for 2 planned restorations along the Quinnipiac River in Meriden and Southington. The removal of ancient stone impoundments will allow diadromous fish to migrate the remaining 16.6 miles of habitat in the headwaters of the river, and will also help to restore the downstream habitat. With the initial field work complete, design is expected to occur through the fall and the physical restoration will take place next summer.

Bathymetric Survey of the Quinnipiac River in Meriden and SouthingtonTo summarize, preparations for the bathymetric survey started off with research of utility records, land ownership, and CTDOT maps and plans. We mobilized to the site for a field survey, including Army Corps and Connecticut-definition wetland delineation, cross sections of the river bottom, and detailed structural surveys of existing dam features. Several thousand individual point locations were captured for 2 sites, including various bridges, river tributaries and a distributary, in addition to depicting the relief of sediment build-up, embankments, cross sections, and long profiles. Finally, Franklin Surveys produced digital mapping in three dimensions for the entirety of the project areas.

East Hartford Flood Control System

East Hartford Flood Control System (FEMA Flood Accreditation Program)

Kevin Franklin has been the Project Manager for land surveying services over the course of 2 years for the East Hartford Flood Control System. The services for the East Hartford Flood Control System have included construction verifications, as-built mapping, as well as comprehensive ROW surveys depicting boundary, topographic, and utility information for the levees. This project spans approximately 4 miles of earthen berms, soil-bentonite walls, sheet pile cutoff walls, and encompasses a series of street and railroad closure structures. The work for the project includes historical land record research and a ROW boundary determination based upon 1950’s era Army Corps taking plans, intended to allow for an analysis of existing encroachments onto Town property.
