Bathymetric Survey and Topography of Portions of the Quinnipiac River

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.

Land Survey for MD Fox Elementary School

Land Survey for MD Fox Elementary School, Hartford, CT

Kevin Franklin was the Project Surveyor for a boundary, topographic, and utility survey of an existing urban school to support site improvements. The record research on this project went considerably beyond a typical review of City Clerk’s records. This effort ultimately involved coordination with multiple City agencies, the MDC, and an exhaustive search for site plans in the Board of Education’s files. The fieldwork was kicked off with a state plane coordinate tie-in, using total stations for ground control as well as GPS. The land survey encompassed approximately 1⁄2 of a city block, and included a “first survey” boundary determination, as only rough sketches were found to depict property line locations.

Boundary and Topographic Survey

Boundary and Topographic Survey for Windham Magnet School, Windham, CT

Kevin Franklin was the Project Surveyor for a Class A-2 boundary and Class T-2 and T-3 topographic survey of approximately 40 acres of undeveloped land. The project included land record research and coordination with local utility services to obtain record data. The field work consisted of re-running an established survey traverse and performing a variety of procedures to verify existing boundary plans and aerial mapping. Additionally, the project involved proposing easements across neighboring properties to provide the school with water and sanitary lines.

Railroad Survey for Metro-North

Metro-North Railroad Survey for Tie Dapping, Multiple Bridge Crossings

Kevin Franklin was the Instrument Person for detailed topographic railroad survey on approximately 25 railroad bridges between New Haven and Greenwich, Connecticut. This project was initiated with railroad safety training to obtain Metro-North safety certifications. It also involved daily coordination with railroad personnel (flagmen). The project was intended to support design work for dapping of the timbers and included precision locations on bridge features such as ties, rails, stringers, splice plates, and back/wing-walls.
