West River Restoration Project, New Haven, CT

Pond Lily Dam Removal on the West River

The Pond Lily Dam was built on the West River to serve a 1700’s-era mill at the site.  The West River Restoration Project, administered by Connecticut Fund for the Environment, was intended to re-open channels for migratory fish by removing the dam which is no longer serving a purpose.  Please see the before and after pictures as the project moved forward.  Note the modern-era fish ladder in the foreground of the dam.

 Franklin Surveys’ Role in the West River Restoration Project, New Haven, Conn.

Pond Lily Ave Bridge

Franklin Surveys provided horizontal and vertical control points at multiple project areas to enable construction of improvements to be at designed lines and grades.  At the north end of the project along busy Whalley Avenue (Connecticut Route 69), we established semi-permanent marks in concrete sidewalks and bridge components in accordance utilizing traditional electronic distance measurement (EDM) total stations.  The south end controls required traversing through a broader reach of the pond and dam area.  During the construction process, a reinforcing cement wall was discovered after the water level had dropped four feet.  The eventual goal is for the West River to flow more naturally and to help River Herring and other Long Island Sound fish get to their freshwater spawning beds.Pond Lily Dam With Fish Ladder

Improvements to the West River WatershedNew Haven Land Trust #pondlily2

The improvements to the river included riffles with natural flat river stones and large boulders to create areas for fish to rest as they swim upstream. Franklin Surveys re-mobilized to the site to perform as-built surveys of key in-water and emergent marshland elevations as the project neared completion.  We utilized the latest in AutoCAD and Carlson Survey software and produced digital survey maps in 3-D, memorializing the constructed improvements and enabling a determination of compliance with project requirements.

During one of the final days on site, our crew happened to be on site the same day as a massive cleanup effort organized by Save the Sound Connecticut.  Some of the pictures show the emerging marsh area and the large amounts of debris that were removed from the river thanks to their volunteers.  What a rewarding sight to see and a great project to be a part of!

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.

Gas Station Geopier Layout

Gas Station Geopier Layout

Kevin Franklin was the Project Manager for construction stakeout and geopier layout at a new Stop & Shop fueling facility. The first task was the recovery and positional verification of the survey control points set by the firm which provided the existing conditions plan. A specialty drilling contractor provided layout specifications and instructions for the assembly of the geopier-specific markers. After installation, geopiers provide for increased footing stability and decreased risk of uneven soil compaction/settlement. This project employed traditional total station and differential leveling techniques to set 103 of these markers in accordance with the 1⁄2-inch positional tolerance, over the course of 2 field days. Additionally, this work called for layout of miscellaneous site features as well as setting bolt patterns to support the canopy columns.

Water Main Interconnect Project

East Lyme / New London Water Main Interconnect Project

Project Manager for ongoing work in support of the design of an interconnection water main in East Lyme/New London, Connecticut. The services have included the establishment of a linear survey control network, coordinating with an aerial photogrammetrist, and developing comprehensive base mapping. This work initiated with GPS establishment of preliminary elevation data at specified locations as directed by the design team. Subsequently, this progressed to field locations for a series of photo target points and field verifications of aerial mapping provided by the photogrammetrist. The key survey goals are to supplement the aerials with ground locations of wetland flags and utility features, to compile assessor’s parcel data, and to depict all of the above on CAD drawings that will encompass several miles of roadway and terrain.

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.

Differential Leveling in Paper Mill Basement

Paper Mill Basement Differential Leveling, Uncasville, CT

Project Surveyor in the field for differential leveling work on the basement level of a working corrugated cardboard manufacturing facility located on the banks of the Thames River. The crew established elevations within the confines of the mill utilizing a nearby CGS benchmark. This work was done in conjunction with a flood insurance plan for the mill’s valuable infrastructure, and was conducted in highly adverse conditions. Large portions of the mill floor were constantly covered in hot paper pulp and the noise from working machinery meant that hand signals were the only effective means of communication. The end result was a series of scribed and marked lines on the concrete columns in the basement.

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.
