John G must have been part of that "master plan". I worked for C-MED NH back in the day before my present gig. The regionalization of the Valley has been talked about for years, it was there with us dispatching Ansonia, Derby, Bethany and Seymour Fire / EMS, and Shelton EMS along with VEMS. NWPS had Oxford, Beacon Falls & Prospect (not the valley but a lot of M/A with the northern towns). NWPS pretty much is the regional area since they took on the majority of the old C-MED NH towns. One of the major hurdles was the ownership of the PSAPs, which for the most part are controlled by most of the city / town PD's, where the 911s actually go first. So the regionalization dispatch center plans were "secondary PSAPs", with the exception of a few, like CMEDNH with Bethany, TN, QV, and KX (RIP) holding the PSAPs for their respective towns. Just think if people listened how different things could have been today.
As for Birmingham, that was only a village and later a borough that comprised the downtown of the town / city of Derby. It existed as an industrial village from 1834, originally named Smithville. It was changed to Birmingham in 1836 upon the urging of Anson Phelps due to its large industrial base, named after the great British industrial center. In 1851 it was incorporated as a borough within Derby and was disincorporated in 1893 after Derby's town government was consolidated with the borough government as a city. All of Ansonia, Seymour, Oxford and parts of Beacon Falls were part of Derby, not Birmingham. Derby has existed since its settlement in 1654 (from Milford and New Haven colonies) and naming in 1675. The entire area was never named Birmingham.
The original Ansonia was just the downtown and North End areas of the present City of Ansonia, settled and named after Anson Phelps in 1844 when he built his new factory there, which was still part of Derby at the time. Ansonia was incorporated a borough in 1864, and its charter revised in 1871. in 1888, Ansonia's borough leaders circulated a petition to separate from Derby, thus in 1889 the Town of Ansonia was created including the old borough, Hilltop, Derby Hill and West Ansonia areas. Ansonia-boro maintained a separate government until early 1893 when the town and borough governments were consolidated into the present city. Ansonia was the first incorporated city between Bridgeport, Waterbury and New Haven, followed by Derby a few months later.
Unfortunately people have really messed up telling / writing the history of what "Birmingham" is / was and 99% of it is wrong. Sorry for the history lesson, but all your thesis are due by Friday 5 pm. Class dismissed!
