Description: Each harbor management area is defined in the municipal town code, and sometimes also mapped in the harbor management plan itself. The vertecies described in the town codes were located and mapped to form these areas; the specifics of each and the source document link is given below. In general, in-water verticies are located on buoys or other navigational features such as breakwaters, lighthouses, etc. These were located on NOAA RNC provided online. Town boundaries, shoreline, and shelfish jurisdiction lines are provided online by the State of Connecticut and were used in the construction of these polygons. Note that there are several assumptions and caviats with this mapping:All Federal and State-published GIS data is assumed to be best available source; e.g., town lines are accurateTown N/S jurisdictions in LIS correspond with mapped shellfish management linesOnly LIS-relevant HMAs are mapped; others exist in the Connecticut and Thames Rivers not represented hereWhere mapped jurisdiction or shellfish lines were not available HMA boarders were drawn as close to the centerline (not thalweg) of channels and rivers as possible. Where southern boundaries were not identified in the relevant Harbor Management Plan, the HMA was drawn to a simplified 30-foot contour running aproxamitely E/W (Groton City)HMA jurisdiction lines tied to features on a nautical chart were drawn using largest-scale (most zoomed in) available chart; at other scales features may be drawn differentlyDefined jurisdictions and sources:GreenwichWithin that area bounded on the east by so much of the line separating the Town of Greenwich from the Town of Stamford as lies north of the forty-first parallel of latitude; on the south by a line running from the intersection of the Town line with the forty-first parallel westerly to Flat Neck Point, thence southwesterly through lighted bell buoy No. 1 east of Little Captains Island, thence southwesterly to red nun buoy No. 2 immediately southwesterly of Great Captains Island, and thence to the State line on a line running northwesterly through black can buoy No. 1 on Manursing Reef at the entrance to Port Chester Harbor; on the west by the line between New York and Connecticut, and on the north by the shore line of the Town of Greenwich, the Selectmen of the Town shall have authority to....https://www.greenwichct.gov/DocumentCenter/View/3180/Harbor-Management-Plan---Chapters-PDFStamfordThe SHMA includes the Stamford Harbor and all of the other navigable waters and intertidal areas of the city below the mean high water line within Stamfor'ds territorial limid, bounded by the projection into Long Island Sound of the boundary lines of the neighboring municipalities of Greenwich to the west and Darien to the east.
